I needed replacement for the AC unit at my apartment. The technician came on time, gave a details description of his findings and options for me to consider. Following that, the work has been scheduled and it was completed at the set time. All the team was very professional. Customer service was very responsive and patient with all my questions. I would not hesitate to do business with them again in the future.

John came to inspect at the furnace, air conditioner, and water heaters. He was beyond knowledgable about everything. He was able to explain the problems and show us what was happening. He was honest and straightforward about everything. The price was more then fair to inspect everything. Theresa set up the appointment easily and was in communication the entire time. I would work with the company again in a second. Highly recommended.

I worked with HeatCool at my business location for the last several years. When my condo also needed AC service I asked the custodial crew and they enthusiastically recommended HeatCool. Turns out theyve been working in my building for many years and were familiar with the systems. An added bonus. They explained what was going on and the work to be done, billed promptly. There were no hidden costs. Professional and a delight to work with. We wont go anywhere else!

Had warranty issue with window A/C. Gave me complete run around. I finally solved issue myself by calling the manufacturer who sent me a replacement unit immediately. Would not recommend this company.

Every mechanic that has come out has been professional, on time, friendly, informative and wore their PPE during COVID (without being asked!). Jessica in the office has always been helpful and quick to respond as well! Highly recommend this company for any of your HVAC needs.

Heat Cool replaced not only my heating and air conditioning units, but they also installed an amazing air cleaner on my system. As an individual with allergies and asthma, this air cleaner has been amazing. I know that the air quality within my home is clean and improves my overall health.

Heat Cool saved me from an $8k bill by repairing an AC unit that other, larger outfits said couldnt be repaired and had to be replaced. The Heat Cool techs were very knowledgeable and repaired the unit within a few hours. I highly recommend.

We had our entire HVAC system replaced by HeatCool. Everything about the whole process was smooth and easy. I have already recommended them to my friends. If you need your furnace worked on quickly and without any hassle, HeatCool is who you need to have do your work!

The team at Heat-Cool Service is exceptional. They are actually located in on the North side of Chicago and have been in the same location for 50 years. They are just so easy to work with.

On time very professional. Furnace working great ready for winter.They have earned all my heating and A/C service buisness.

They are great people to work with, reliable, timely, and they do quality work. I will always use the great folks at Heatcool for all my heating and air needs.

Ive been a HeatCool customer for 18 years. Theyve installed space-saving radiators in my kitchen, heating/cooling systems in the attic, hot water heaters, a boiler and chimney liner, and central air conditioning, in addition to doing annual fall/spring servicing of the heating and cooling systems. Theres no one I trust more for fair, dependable, knowledgeable service. Thanks John!!!

John from Heatcool came out to help me fix my A/C problem. My basement is freezing and my top floor is a sauna. He quoted me a fair price and came back a few weeks later to install. Fast, professional, and courteous, John has made it so much nicer inside! These guys are pros!

Heat Cool is first class service provider, I have always been impressed with knowledge, and ability to get the job done.

So after 10 days of sweltering heat in my apartment with NO working A/C, my landlord FINALLY contacted John Freson of HeatCool Service Co. Punctual, responsive enroute and while on-site. Im a long-time renter. John treated me as if I was paying the bill! Courteous, kind, professional with an explanation of what was wrong and what he fixed. He even did some dog TLC on the way out. A/C working great -- temps dropped inside from 84 degrees to 74 throughout the rest of the day. This is what customer service is all about. Thanks John for your service. I told my landlord that he needs to keep you!

Not a professional or reliable company. Double charges for service calls for the same problem on the same appliance. Charges over 100% markup on parts. Save your money and take your business elsewhere.

John and his team are always available and do a wonderful job. I have been working with them for over 15 years.

HeatCool was great! They worked with us and our landlord to replace both of our in-wall A/C units quickly, just in time for Chicago summer. They gave us a fair quote & they were always friendly and courteous.

Great friendly service! Have been using them for years.

John was very accommodating and willing to answer all my questions and manage my specific requests.

My apartment needed some MAJOR work done and this company was outstanding in every way. John Freson, who runs his team of courteous and professional contractors, is extremely thorough. He explained every process clearly so that even a layman like myself could understand not only the work being done, but the costs attached. I was so impressed by his honesty and meticulousness that I went through him to get additional work (plumbing, wallpapering, etc.) done as he has a wide variety of contractors to do various jobs. Heat Cool gets my highest recommendation!

John and Oscar came out to our place in Rogers Park to replace our furnace. These guys are awesome! Theyre friendly, fair on price and went above and beyond in service. Our new furnace is working like a charm, and the guys went around to make sure all the vents in our condo were working properly. After they left, the furnace room was cleaner than how they found it. Great guys and great service!

I own and live in a vintage 4-flat in Humboldt Park where each unit has its own heating unit. The second floor units wall furnace stopped working and I called Heat Cool for service. The tech sent out to get it running again arrived Monday morning and after checking and testing several things soon found the problem. The unit is working like new, and my tenant is warm and happy. I will certainly recommend this company to others. Thank you!

Our family has been with Heat Cool for over 20 years. Their service is great and they always finish the job and give us a great price.

Very good service. They do window and wall units as well, a service hard to find in Chicago. Everything was easy and quickly taken care of, customer service very pleasant. A real pleasure!

I went there on 7/10/2020 around 12:30 pm, the front door was locked and they would not pick up their phone. Pretty frustrating. I eventually left around 1:05 pm after waiting for 35 minutes for anyone to come to the door or answer the phone.

The first service we called said we needed a new $7000 system.HeatCool repaired our a/c for less than $800 and we have not had one problem with their work.

Heat Cool is the BEST!Look no further. Not only did I get awesome service I got an education from a man who knows exactly what he is doing. Thanks John!

Guys came out today to replace a stacked heater/ac unit and finished the whole thing in about half the time I expected. Very professional, clean, organized, and courteous. Highly recommended.

Friendly and helpful professionals. Great prices for equipment and service. They offer wall unit air conditioners among other things.

Very friendly and great professional service at a decent price! I had two systems replaced that were over 40 years old in under two hours.

DISASTER! This company makes false promises. I got SCAMMED out of my money. Do not work with this company.For instance they promised that I could apply the fee for the initial visit to installation. They charged me $184 to tell me my A/C units were old (which I already knew) and then refused to honor the deal they promised.Their rates are too high. Their service is poor. And, they lie to their customers. AVOID this company!

Best Heating Service Company in Chicago. Thank you Heat Cool

Professionally done.

Great heating guys. Work done on time/

Detailed Review: decided to utilize their service to install a thermocoupler because I was (1) time constrained and (2) it would take a week or longer to get the part. I informed them of the website that had the part and the part I was interested in, a thermocoupler, and whether they could do it as it would save me time on the shipping and my schedule was getting hard to make time for it. I informed them of my exact model and supplied them the website as Kenmore is a Sears product and the website is the Sears Direct Catalog. Despite all of the advanced information I supplied, they sent a guy out who didnt have a compatible thermocoupler and informed me that it would take another visit [and additional cost] to do it! I sent an e-mail wanting confirmation why none of what I supplied information-wise wasnt even considered apparently and they called back informing me that they didnt have a compatible piece and that it was very hard to obtain. The problem with their response is:1- I GAVE THEM the direct website that had the EXACT Part!2- If they even bothered to spend 5 minutes looking at that info theyd have learned spot-on if they had the right part.2a- If they didnt have the right part they could have had the courtesy of saying we dont have that exact part you can either order it and we can install it so you dont have to pay an extra service call.2b- They could have said they just couldnt do it.3- They came out anyways saying they couldnt do the job because they didnt have the right part [despite my providing them all the info of my model the prior week].4- They called to inform me as a followup to my original complaint that the part was hard to obtain and that it was a different style than what they are accustomed to carrying on their vans. Well THATS WHY I SUPPLIED THE EXACT WEBSITE OF THE PARTS FOR THE EXACT MODEL I WANTED TO BE SERVICED.Conclusion: I ended up calling and leaving a voicemail with Sears Direct and informed them of what I needed and why and what would I be looking at. Called me and left an e-mail reply per my request: they cant install it any faster than they can ship out the part but they can ship out the exact part I need and if I have trouble I can get an installation performed for a bit less than the service call I placed with HeatCool.Additional Notes: Im not trying to be a pain and I do service calls as a part of my line of work but I also get as much information as possible from a client before performing a job and making them pay. I seriously warn that customers should do some research on their parts and components and contact the manufacturer first! Keep in mind I wasnt trying to save money but time; that taking the time to change my schedule and commit to this problem was creating issues with the people whom needed the service and my job commitments. In the end, it cost me both and if I ultimately chose the save money route of ordering the part from the Sears website of the actual part, having a Sears operator come out wouldve still been less money and apparently have been faster.Its also hard to have faith in a service where if you supply everything that is relevant to the job requirements and they come out and say they dont have the part its really more demonstrative that, personally I feel, (1) they didnt care to look at the info you supplied and (2) they didnt care if they solved the issue and that the customer will simply pay again to have them do the work.The part I ordered is still shipping from Sears and I may just opt to have a coworker take a current contract so I can do the job I actually asked HeatCool to do which means that I ultimately lost more money and time using them versus had I opted to do it myself or even pay Sears to do it. Im not advertising their (Sears) services but the fact is they DID at least inform me of the issues before hand: (1) they cant have someone come out with the part, (2)suggested I order the part first and then schedule the appointment and (3) verified the part I ordered was the compatible one.

I am a building Engineer and Bob is who I call when I need service on a PTAC unit.He is one of the few who will actually come out and fix your A/C while other companies just try to sell you a new one.

These guys are awesome, incredibly knowledgeable, honest, a pleasure to work with.

I have a high rise unit on Lake Shore Drive and they know my building inside & out. The work gets done right the 1st time.

Great hvac comany

Heatcool is an acceptable business ,with pre explained prices .My initial review was severe .my apology.

Very reliable, friendly, great service.

Be extremely weary of dealing with these guys. During a service call I was promised free parts under warranty and told I would only have to pay for labor. After the repair was finished I was charged about 75% of the cost of those parts and never received an explanation as to why. HeatCool wont even answer my emails now. Very shifty and dishonest company.

When I needed help these are the guys who came to my aid.
