Mitch Damian rated it 4/5: The first guy that came last Sunday (Pat) was good he thought the pipe was a city issue and didn't want to charge my aunt almost 500.00 to check, so the city was called out and they said it was a secondary line that wasn't connected to anything and they informed Pat on what needed to be done and he was able to have someone scheduled to come back on Monday morning to do the repair. That person did come out and removed some of the pipe but not far enough back to stop the leak. So when I was back at my Aunt's house I saw that it was still leaking, so I called and spoke with Heather and she was understanding with my frustration of it still leaking and set up for someone to come back out free of charge after the almost 1000.00 repair charge between 11am & 2pm, and Sean was arrived at 10am and hour early which was awesome and he was able to repair the leak with in less then a hours time by removing the cap valve and cutting the pipe where it needed to be cut in the first place and recapped and valved it off and now my aunt and I was grateful and happy with the work that was done!!!!!!! The first two photos are of the leak , third photo is what was done on Monday and last one is the completed repair.

Rae Prays rated it 5/5: Four Seasons was very professional, informative, and responsive. Within 2 days of my tune up, they were back onsite to replace my old furnace (1983) and the motor in my other unit. The servicemen who installed the new furnace were respectful of my property. They made sure to remove the old unit and everything else, so my place pretty much looked like before the installation. They answered all of my questions and even provided me with information I didn't even know to ask about. On top of all that, they linked me with seamless financing that worked perfectly within my budget. Now I have a brand-new unit, a satisfied tenet, and heat that works much better than before. Peace of mind is what they really provided. All without straining my bottom line. They have definitely moved up to be my "go to" servicer for all things heating. Keep up the good work guys.

Tom Lawler rated it 4/5: We had a NEW hot water gas BOILER installed just before the cold winter weather, so HAPPY with it. The installation took a day, two guys working taking out the old one. The guys were polite and professional. They explained what they were going to do. We did have a small dripping from one new part that was replaced a few days later. Good competitive price as we got three estimates. Best warranty of the three.
Juan Gomez rated it 3/5: So the initial contact was fine. The prices were high but I understand good work isn’t cheap. What I didn’t expect was damage done to my house and the gaps they left open for me to cover. I paid nearly 13,000$ for a new hvac and ac system to be professionally installed. Damages to my siding and holes left open where they drilled. For the amount of money I am paying I expected much better than what I received.
Brian Hambric rated it 1/5: I was going to let it go but where do you draw the line? I’m just a man trying to do the right thing until Four Seasons Heating and Cooling threw away my Hot Water Tank. I’ve got to be crazy. My igniter on my 1 year old hot water tank stopped lighting. So I called Four Seasons Heating and Cooling for maintenance. I had been a client for 6 years and trusted they would get the job done. What I didn’t expect was to be lied to and disrespected in my home trying to get me to say something that wasn’t true. And they did all of this knowing my mother was at risk for stroke. They sold me a new hot water tank for 3,800.00 dollars. But when they installed it. It didn’t work. Why? Because my hot water tank wasn’t broke. When I asked for my money back. Seeing the hot water tank didn’t work. I was told they had to speak to their supervisor. When I had to wait they said they would talk about it with their team. Then they told me they had to inspect the hot water tank to make sure it was okay. They sent a supervisor into my home and tried to get me to say something that wasn’t true. The same supervisor started pointing out problems he saw with my home to try and get me to react. All the while my mother is in the other room listening and upset he’s lying. I don’t know what I did to deserve this? I have gone 11 days waiting for there answer and Today they tell me it’s been past the 3 day limit to return hot water tank. To be continued…

Hillary Wiedemann rated it 5/5: Adrian and Kevin provided exceptional installation service. They were timely, thorough, courteous, and friendly. For my AC installation, we had to involve a crane to remove the old unit and install the new one, which I dreaded, but that part of the process was easy breezy! Michael provided exceptional sales service as well, explained the options thoroughly, and was friendly and respectful. I was dreading having to figure out a new AC and furnace, but this crew made the process actually pleasant. I appreciated also having text messages and calls to confirm everything, eased my my a great deal. The new AC is great, cools everything and is so quiet! 100% recommend anytime!

Stacey Shroyer Piotrowski rated it 5/5: We had a great experience with Deljo. Last summer, they came out and repaired our aging AC unit, and got us through the end of summer. We met with Michael C in the spring and he helped us find a new unit that fit our needs. He was very kind and answered all our questions well. When we had the new Carrier installed, David R did a great job too. He was even careful enough that my plants survived the installation too 🙂 Deljo even sent us a box of cookies as a thank you, which is a nice touch. We appreciate the solid service from everyone we've worked with from Deljo and would certainly call on them again for any future needs.
Mikey Affinito rated it 5/5: Absolutely would recommend and will always use Deljo in the future. We needed a rooftop unit removed and a new one installed. After several quotes (some flat out said no because the crane was "too tricky" for their operaters) Brandon provided the most professional and thorough experience.
Brandon was very detailed in explaining the steps the installation would require, explained the billing point by point and answered all of our questions/concerns which was very reassuring. The installation went very smoothly, the team, like Brandon, were professional, efficient and friendly. They also followed up several days later to make sure everything was running smoothly. Honestly, some of the best communication throughout the process of any home services I've experienced as a homeowner.

Big thanks to Brandon and the team, we were so glad to have an awesome HVAC system, especially in this hot summer heat!

Manuel Rocha rated it 5/5: Barton and Andy were great! They did a great job installing my new AC unit and furnace. They were friendly and professional and worked a really long day to make sure things were done right. The whole experience with Deljo was excellent. The technician, Tyler, who came out to check out my system and clearly explained what the issue was. Michael then carefully walked me through the different options and was really helpful in answering my questions. I plan to sign up for their service plan.

Leyla A rated it 5/5: Five Million Stars ! Deljo won me over from the initial estimate to after installation follow up care with Jen. Michael C and his Irish eyes could have sold me an empty Adidas box and I would have Run like DMC miles to Niles. My Installation Crew arrived early and on time! What every Chicago lady dreams of arrived at my door, Polish pride, big muscles, South Side Irish accents, trucks and cranes, and big beards all in one day. I was lucky enough to meet Wesley, an extremely polite and kind soul with a passion for integrity and all-inclusive trips to Cancun. Bearded, blue-eyed Chris (sorry ladies, he is very much engaged ) was equally engaged on the job as he paid attention to detail and welded HVAC parts together sometimes with a fire torch. Windy haired Richard stayed up on the roof most of the day. He packed his own food and drinks and all I can say is that the A/C is on right now and I'm chilling in it & feeling great with the thermostat set at 68. Today was a sunny and hot 78 degree day in November in Chicago! Deljo made spending Benjamins so much fun and made a lifelong customer out of me. Thank you Jen, Michael C., Wesley, Chris, and Richard.

Eliza Lourdes rated it 2/5: HOLY SMOKES I just called this business to ask about installation of a Nest thermostat connector. Not the thermostat as well, just the small connector pictured below.

After trying to troubleshoot why our thermostat wasn't working in our new place I found out from a friend that we need a connector added onto our Spacepak unit. According to him (he is an HVAC company owner and tech out in CA) this should take all of 15 minutes MAX and he encouraged me to do it myself. I told him i'd first call around and ask folks what they charge since I don't want to take a chance (even though I am fairly handy).

All Temp quoted me $475 haha. What?! I asked for clarification because as you can see this small object literally only needs to connect to a few wires and thats it. I thought maybe she misunderstood me, but no she said the owner confirmed the quote.

Hard pass. I don't appreciate being price jammed because it's summer and you think my a/c isn't working. It's working just fine with an old school thermostat we just wanted to use our Nest one.

Chaoju Xiao, Ph.D. rated it 5/5: This review was 5 years after our AC (Mitsubishi mini split) installation and Service with All temp. They certainly deserves 5 stars review rating with their dedication and professionalism through the years. John did an excellent job in designing the lines for the initial installation of this mini split AC system for the 60 years old house with no central AC duct in place. They took care of issues might come up in the initial tuning up of the system. They sometime had busy scheduling, but they always tried hard to help as soon as they became available and performed great service. Special thanks to their dedicated Team! The nice thing I learned about All temp. is they make great effort to retain their employees, which can certainly contribute to the great service All Temp. provides. They charge reasonable price all the way along also.
Mark Testin rated it 5/5: All Temp installed and serviced my furnace and AC. My furnace is 20 years old so they are the first ones I called for a cleaning and quote on a replacement. I had Marvin come out and clean and inspect the unit and it is working great! He knows his way around the system, was very thorough and explained everything. He wrote up a quote on a new furnace and AC and explained my options. Marvin is very nice to work with and confident and I will definitely consider All Temp for my furnace replacement.
Dave Cooper rated it 5/5: I had a great experience with this business. They came out to service my furnace and the tech Josh T. was very nice and knowledgeable, he showed up perfectly on time and was very respectful of our house. He was very personable and professional as he explained everything he was doing, how it should work, ways to maintain the furnace and even fixed a repetitive whining noise that had been a concern and a nuisance for a while. He labeled everything in the area for easy future maintenance and did a thorough job of making sure everything was in perfect working condition before he left.
TL;DR A+ would highly recommend the business and specifically tech Josh T. based on my experience.

Matthew Ardi rated it 1/5: I called for emergency service because my hvac heating system did not work and the temperature dropped below 50 degree. I called emergency service, asked for the fees and agreed to it. I was told a tech would be dispatched.
The tech gave me a heads up call that he's coming, because I was not around, I provided instruction to ring my neighbor doorbell so they can help the tech get into the unit. The tech agreed that is fine.

Then I heard no update, luckily my neighbor kept me updated. They saw the van by the front of the building but didn’t see anyone coming out of the van. So I called the tech and he was telling me he waited for 20 minutes and no one rang the bell.

When in fact, he didn’t even step out of the van and he left after 5 minutes just idling in his van. How did I know that? It’s captured by this video below and see the timestamp.

If they just be honest about it, and told me they could not fulfill the emergency request, I could have gone with someone else and avoided damages.
Very unprofessional and dishonest.

Mark Marquardt rated it 5/5: This summer we had Guardian install a Unico AC system in our almost 100-year-old bungalow. Yes, it was expensive, but not only do we believe it was a good investment, now we can’t imagine how we lived without it for so long.

The first person we met from Guardian was Jasper, who came out to give us an estimate. Another vendor rep who came out took a quick look around before giving an estimate, but Jasper took his time to get a feel for the layout of our old house and to calculate how a system might work best, while also listening to our needs and concerns. This got us off to a good start.

Once we signed the agreement, the installation process got started within a couple of weeks. While labor shortages are impacting every other business, Guardian sent a full crew out every day that included seasoned senior professionals who not only managed the crew but also did a lot of the work. We want to call out specifically Steve and Enrique.

Steve was the main supervisor throughout the installation and did a phenomenal job – from working his Paul Bunyan frame into the super tight spaces in our attic to managing team changes to talking issues through with us and coming up with brilliant solutions.

Enrique brought incredible care and attention to detail to all the work he did. Unfortunately he fell ill early on in the process but he did return at the end and continued to show the same care spending extra hours to make sure the system was ready to be turned on and functioning properly.

In terms of the results, the system is working perfectly on our first floor. Initially the upstairs attic/loft was still a little warmer than the main floor. John from Guardian came out and was prepared to add more vents and go however many extra miles it took. We are so impressed with Guardian’s commitment to quality and service. We really appreciate that this is a company that doesn’t walk away after they make the sale.

Sarah Johnson Ciarleglio rated it 5/5: We called Guardian when our AC went out. We bought our house last year and it is very old, the AC units were older than me!
Jasper came over the next day and did a thorough inspection and outlined what we would need done. He was very kind and professional. They had a cancellation and were able to come the next day. We needed 2 AC Units and a new furnace, as well as duct work and new thermostats.

Rory, Eric, and Jonathan (I may be misremembering that last name) came to complete our project. We have 3 pets and were both working from home. They were AWESOME. Very kind, respectful of our pets and our home, and respectful of the fact that we were both working. They explained everything to us, answered all of our questions, and did a great job. The GM and owner even came by at the end of the second day (it was a 2 day project) to make sure everything was completed properly.

Jasper kept in touch throughout the project and made sure we had all of our questions answered. Our house is so much more comfortable now and I’m so glad we went with Guardian! Thanks Jasper, Rory, Eric & Jonathan!
Keaton Nankivil rated it 5/5: Guardian provided exceptional service throughout our work with them. We moved into a new condo during one of hottest weeks of summer. We found out that our newly installed thermostat did not work and called Guardian to help troubleshoot. They were out the next day and immediately noticed that our entire system was obsolete. He called his team and someone was out that afternoon to assess the system for a new installation. While we waited for the installation team, Guardian even delivered a portable unit to keep us cool. It was above and beyond service.The team was out within a week to fully replace our furnace and AC. They were also dealing with a difficult closet install and were able to find a great solution while creating minimal additional damage. One of the team members was even able to recommend an outstanding contractor to help repair the walls after installation. After the install, they came out a couple of days later to redo the filter to provide optimal performance. Lastly, they helped us navigate financing in a very professional way. They paid attention to every detail and were absolutely great to work with. Our AC system has been on since and made life so much more comfortable.
We were lucky to work with Tyler, Allen, Rory, and his crew for the entire process. We highly recommend Guardian if you are in need of heating & cooling support.

Diana Villafuerte rated it 5/5: I have the protection plan for my boiler and part of that is an annual regular preventive maintenance service check. Fortunately, a staff member, Meghan, contacted me to renew my plan subscription and schedule an appointment. Service technician Nelson, along with trainee Ray, were assigned to my home. They both were professional and courteous. The PM check was thorough and efficient. They answered my questions and confirmed my system was working properly. I appreciate their professionalism and work ethic. I would request either of them for future service calls to my home. Overall, I'm pleased with Guardian Heating and would recommend their service.
Drew Malone rated it 2/5: I do not have any service experience with Guardian. However, I can tell you I am quite displeased with the mess they left on my patio after replacing my upstairs neighbors AC and Furnace. Please clean up after yourself and don’t leave your garbage for someone else to deal with. I run a business and you must button things up and clean after yourself. Leaving garbage, tools, extra supplies is not acceptable regardless of the quality of your craftsmanship. There is also damage on our metal staircase landing which I will have to repair because one of the workers dropped the old furnace while removing it.

Shan Xiang rated it 5/5: Our AC was not cooling very well and recently it started to make high pitch noise. We called Chicago HVAC Repair Doctor and Rafael responded quickly. He visited us the first day and the second day he got the parts and came to do the repair. He replaced the motor and replenished the refrigerant. The AC is running smoothly now and it cools very well! Rafael is very professional, knowledgeable and experienced. He explains things clearly and he really cares customers. I highly recommend him.
Edward Swierczek rated it 5/5: The employees at Chicago HVAC Repair Doctor went above and beyond to replace my water heater tank that had cracked. Erick, Joshua, and Felix who all arrived during their stated time window were professional, extremely courteous, and worked quickly to diagnose the issue and install the new water heater. Truly exceptional service at a fair price. Chicago HVAC Repair Doctor, you've earned a new customer. I am happy to highly recommend this company to others too.
Brian McDonnell rated it 5/5: We used Chicago HVAC Repair Doctor to replace our rooftop HVAC package unit and they made the whole process a breeze.
When our heat stopped working last spring, I knew we might be in for a large expense considering it would involve replacing our nearly 20 year-old rooftop HVAC unit. The process of collecting estimates was intimidating not only in the costs but logistics (the installer would need to hire a crane!) but we were thankful to find Chicago HVAC Repair Doctor with their competitive pricing and excellent customer service.

The install went off without a hitch, crane and all, and the whole process from start to finish took a little under 2 hours.

While I was initially very anxious at the scale of this type of rooftop install, Chicago HVAC Repair Doctor put my concerns to rest and I highly recommend them.
Tamra Baer rated it 5/5: I have only had the best experiences with this company. I’ve installed two new furnaces (different units). Each time a really good experience. Today I had a small gas leak (on existing pipe fitting) on Sunday. Joshua came and did an amazing job to fix the problem and performed regular maintenance. Each experience, the service and quality is above expectations. I highly recommend them for your HVAC needs!

Keith Forshaw rated it 5/5: I have had very good experiences with Mike and his team over the years at Oasis HVAC. A few years ago when we first moved into the house, another HVAC company provided maintenance to the system while disconnecting the overflow drain switch on the AC coil pan. Therefore the unit ran for days and flooded our downstairs DEN. Oasis saved the day, reinstalling the switch and fixing the system. Now our old system is 19 years old and makes no sense to pay $1,000 to fix it so yesterday we decided to replace it.

Mike came out to look at the old central air and heating furnace unit which is in the upstairs of our bungalow. Seated horizontally, it was going to take a lot of work to get the old unit out and the new unit in. We selected the American Standard (highest rated in the industry a.k.a. Trane) 80K BTU 2 stage furnace/central air and an American Standard 3.5 ton 13 seer A/C unit outside. The team of 5 guys came out to install it just 4 days after signing the contract promptly at 7:00am and completed the entire job at 2:30pm. They had originally thought it would take a day and a half. I also elected the annual maintenance which they come out 2 times per year and will also cover labor, along with manufacturer's hardware warranty for 10 years.

The units are EXTREMELY quiet, you cannot even hear them run. Especially being outside and entertaining the patio. My electric bills are also expected to decrease significantly. The 19 year old previous system originally purchased from Sears was costing an additional $400/month just to run in the summer to to mention the old freon was $220.00 per pound.

I am VERY satisfied with Oasis HVAC, quality product, quality service, attention to detail, professional and courteous. They also don't change extra for after hours emergency maintenance and have been easy to reach in the time of need and arrive at the house in 1-2 hours after creating an appointment.

Oasis HVAC comes highly recommended from a highly satisfied customer.

Keith Forshaw rated it 5/5: I have had very good experiences with Mike and his team over the years at Oasis HVAC. A few years ago when we first moved into the house, another HVAC company provided maintenance to the system while disconnecting the overflow drain switch on the AC coil pan. Therefore the unit ran for days and flooded our downstairs DEN. Oasis saved the day, reinstalling the switch and fixing the system. Now our old system is 19 years old and makes no sense to pay $1,000 to fix it so yesterday we decided to replace it.

Brian Nordyke rated it 5/5: The team at Oasis have been extremely helpful and I will work with them again in the future for any HVAC needs. Not only were they fair in pricing, they were always prompt, responsive via phone, and willing to come out multiple times to work with roofers as well to ensure the job got done right. Highly recommend.
Andrew Carnegie rated it 5/5: Fantastic company! AC went out on a Sunday…reached out to Oasis via their website hoping to get them scheduled for some pt during the next week. I got a call from the owner within an hr (on a Sunday!) asking if he could have someone on-site at 7am the next day. Super responsive, quick repair and good fair pricing. Can’t recommend Oasis enough.
Taylor MacPherson rated it 5/5: Professional, timely and thorough, would recommend!!
Woke up this morning with no heat. Called a couple other places that were already fully booked due to the extreme cold.

Called oasis and got an appointment within a couple of hours. The technician showed up EXACTLY on time which was an incredible bonus.

Quick diagnosis and repair (issue was on exhaust outside the wall, no parts replacement needed) stayed on site to make sure there were no other issues, friendly and willing to talk through all of our questions. A best case scenario on what could have been a very stressful day, will call oasis first for any future service needs!
Nicole Cisternino rated it 5/5: We had a great experience with Oasis. Our furnace went out on a Saturday and they installed on Monday. They were professional, on time, and responsive. I never felt like they were trying to sell us. Great service!

Carolyn Stewart rated it 5/5: With winter coming, I decided to take advantage of the coupon Chatham Comfort Control made available to get my furnace cleaned and checked. However, on the morning of my appointment, they called asking to reschedule for later that day. Apparently another customer's boiler required an emergency repair and they were readjusting that days schedule in an effort to accommodate everyone. Since the maintenance work I was having done was not urgent, I agreed to reschedule for the next day. Early the next morning, service technician Nate, arrived on time and got the job done. He was personable yet professional and I was very satisfied.

I have a lot of respect for a company that provides a great value along with excellent customer service. Particularly when they care enough to do all they can to resolve a customer's problem. It will be my pleasure to tell my family and friends about Chatham Comfort Control.

Ayodele Macarthy rated it 5/5: My first call for an estimate was great. They arrived in fast, 15 minutes! They completed the assessment and gave me an estimate. They arranged my repair appointment quickly. Jon and his crew were knowledgeable, responsive, respectful and polite. There was a supplier delay and Jon contacted us swiftly to explain this. They arrived on time, put down drop cloths and worked at a good pace. We are pleased with their services and would recommend this company.
Lynn Gills rated it 5/5: Jon and his technician came to my home on time confirming his visit prior. He first took a look at my thermostat and realized that I had it on the incorrect setting. He positioned it to the correct mode then went into the basement. He checked the furnace which he said was in good working order & resolved the matter in two minutes. I asked him if he would be my new heating guy lol. Jon and his team are awesome! I will be calling on him for any future heating needs!
Jo Duke rated it 5/5: Jon and his crew are the best. They came to take a look at my furnace which was leaking water while running the A/C. I was previously told by a different company the coils were bad and needed to be replaced and that my furnace had a little life left in it. After receiving a second opinion by Jon it was determined it was best to replace the entire furnace and AC unit. Jon made this process easy and kept it professional. His team arrived at the time they said they would and were done when they said they would be. The price was reasonable and everything is working fine! I highly recommend!
Tony Gomez rated it 5/5: Jon, and the rest of the folks at Chatham
Comfort Controls, are consummate professionals. Jon is responsive, empathetic, and incredibly knowledgeable. In my situation we had a busted boiler in the dead of Chicago winter. I called him after hours and he was there the next morning working on a solution. It took several days but Chatham did not let me down. They were acutely aware of the desperate situation i was in and worked tirelessly to resolve and they did. I would recommend Chatham Comfort Controls to any dealing with HVAC issues. You will not regret it. By the way, Jon is a super sharp guy- truly knows his stuff and he will explain all the inner workings of the system and the problem so you fully understand.

P. Gilmore rated it 5/5: Thermostat replacement led to seriously consider replacing my nearly 25 year old furnace and AC. TDH was one of several that quoted the job. They took into account I already had a brand new thermostat, and provided a very competitive price AND install in 4 days. During a heat wave, that was phenomenal. Installation and removal complete in single day. Excellent cleanup. I won't hesitate to use them for maintenance.
Financing was offered at 0% if paid within 18 months – but Wells Fargo deferred interest is 28.99% -just so ya know.

ZEROME Cage Sr rated it 5/5: Awesome service from start to finish, the sales rep Ken, was fantastic he was very professional did a thorough inspection made his recommendation and no pressure sales pitch I felt he was very open and honest, this made the experience that much better. First impression are lasting thanks Ken, I also will like to say kudos to Jim, he followed up to make sure I understood the proposal and if I had any questions he was open to answer and thank me for the opportunity try and win my business. I must admit before choosing TDH, as the company of choice l got four other estimates and it came down to the service every company has an opportunity to raise the bar of service to be compared too, and TDH, definitely did that for me. The installation by Jose, the the lead tech on this job was great, from the start he was on time as promised and they worked with precision paying attention to every detail, used protective items and cleaned up after they completed the service. I’m a very satisfied customer and I strongly recommend this company
Nadeige Uwamba rated it 5/5: TDH was absolutely fantastic! I called them on Friday afternoon and asked for a quote to replace my AC/furnace system. Within hours I received it ($4,000) cheaper than other places. They were quick to schedule my appointment and made sure that everything was seamless and clean and that it was working. I 100% recommend them! Best in the city!
Marylast Magsalin rated it 5/5: Communication- the company is very responsive in all inquiries and came the next day after we call for a free estimate. Bernie came, he is nice enough so we got convince on how he explains the pros and cons of the producr and services offered by their company.
Good Value/Budget-they can work on to your budget and offer 18mos. 0% interest, Jackie helps us to work with the bank for financing.

Professional/On-time – Jose and Andres came on time on the day of installation, they uninstall the old unit and put up the new unit,,,,,they even clean up and make sure leave everything si in place before they leave.

Lastly Thanks to their boss Tim, he communicates well to his team, and answers all our question in real time…Our transaction went smooth and everything goes well.

I highly recommend this company.
Mark Daugherty rated it 5/5: TDH installed a Trane/Mitsubishi mini split system in our home in November 2022. I received multiple quotes for the project, and TDH was the most competitive. I appreciated that Bernie provided us with a quote the same day – other contractors took weeks, or never responded at all. After working with a third party to provide a load calculation to determine exact system sizing (pretty close to what TDH initially proposed), we specified a 5 ton system with 2 outdoor condensers and 6 indoor heads.
Installing this type of system in a vintage brick structure is very labor intensive. Thankfully, George and the other installers were exceptional; they were very detail-oriented throughout the process. His experience and expertise with the system and various components was apparent. He took the time to discuss all of the equipment and line set locations with me as the project progressed, and he was very polite and considerate of keeping our interior spaces minimally disturbed. Post-installation, TDH quickly addressed the few questions I had. Overall, a great experience, and I would recommend TDH for anyone's HVAC needs, especially mini split systems.

Mark Tepper rated it 5/5: I called the day before Christmas Eve and they came the next day. They came during the window they stated and were very professional. Handled the issue quickly and professionally. I would definitely use them again.

Paul Jones rated it 5/5: Requested a service call on my father-in-law's house because of great local ratings here on Google. AC was dead and they quickly found that the system was leaking. They took the time to clearly explain how patching the leak and then putting new refrigerant in the system would create pressure and probably crack the 27 year old system again. Knowing that his furnace was also 20+ years old, I asked for a quote and timeline. The quote was outstanding and thanks to their pro partnership with Rheem, they are one of the few guys that can still get their hands on equipment quickly. From the initial call for service to final installation was only a few days and now my father-in-law's house has a completely new HVAC solution that will last for the rest of his life.
When everything was finished, they walked me through it, made sure everyone was satisfied and there were no games with the final invoice. If you're in their service area definitely give them a call. I wish there were 6 stars available for companies like this.
Teresa Lally Seymour rated it 5/5: Highly recommend Robert and his crew. When our furnace broke, we got a new one very quickly. He was very prompt to reply and addressed all our questions very thoroughly. The installation was efficient and clean. Will definitely be using Miron Heating and Cooling again!
Ethan Brady rated it 5/5: Robert and his team are very professional and organized. From booking to repair, Lucas and Matthew were timely, efficient, and provided a good service at good value. I will not use any other service besides MIRON going forward.
Mark Tepper rated it 5/5: I called the day before Christmas Eve and they came the next day. They came during the window they stated and were very professional. Handled the issue quickly and professionally. I would definitely use them again.
Thomas Podlipni rated it 5/5: My experiences with Miron have always been great. They are professional, efficient, and kind. The latest person to service our heater, wore slippers over his boots, identified the issue and covered the details with me, and resolved my problem quickly. Miron personnel record all the aspects of their work creating a though record of each visit. They also provide recommendations for best HVAC practices.
Lastly, they got our call on the coldest Chicago day this December. They were swamped and were able to provide us service same day. Would recommend them to anyone.
