HVAC reviews across the US

Sean arrived on time and was very efficient! He is very knowledgeable. He is honest and straight forward. He answered all my questions for me and gave me suggestions to keep my furnace in well working order. I would like Sean to come in the future to my home for my regular maintenance to my A/C and furnace. Thanks again Sean!!! 🌟🌟🌟🌟🌟

From the Initial set up call with Nikolina to the service technician Piyush, it was an amazing experience! Great customer service, friendly, and fast. Piyush really knows his stuff! Very patient and knowledgeable. Explained the issue thoroughly. Highly recommend!

Martin was thorough, patient and kind. He told me what needed to get done and took time to explain things in a way that was clear and understandable. He took extra time to speak to my husband on the phone to explain about a gas leak he found, which was not part of the maintenance plan we have, but still very important to address. Thank you Martin!

Jose and Keo were just great. They arrived on time and were very polite. They found the problem, but were unable to fix it, as it needs to be replaced. However they set up an appt for another guy who will review our situation and options with us. So far, my overall impression is very positive.

Today we met with Sully to arrange the purchase and installation of a new HVAC unit. He also was very courteous and helpful. While it wasn't great that I need to purchase a new unit, he made the experience as painless as possible.

So far, my experience with One Hour Heating & Air Conditioning has been terrific!

Had the absolute pleasure to meet Mike Sullivan today for a furnace and a/c replacement estimate. He was informative and worked hard to get us a fair price. One Hour Heating & A/C is the only company our family uses and Mike has been great to not only my home but also took great care of my parents!! Thanks again One Hour!

Mark did a tremendous job. He was friendly, courteous and respectful every step of the way. We truly appreciated his service!

Thanks so much for the complete furnace cleaning/inspection and the replacement of warm part. I have the reassurance that I will not have any heating problems this winter!

until after midnight before any real cooling took place. The humidity levels seemed too high.

Jose immediately identified the issue and got to work rectifying the situation. He also showed us how to do some preventative maintenance that would ease the burden on our system.

From the office scheduling through Jose’s visit we were thrilled with the fast, reliable service delivered by kind employees. We highly recommend One Hour Heating.

Jeff was absolutely awesome. Everything you could ever expect in a service visit. He showed up quickly, was knowledgeable, friendly, and helpful to the customer. This service call was a pleasure.

My One hour service representative was very knowledgeable and gave me the answers I needed. He provided excellent service.

Ulises Hernandez from One Hour Heating and Air did d a wonderful job checking the AC unit. He was very professional and thorough and answered all our questions. He is a wonderful employee and we hope he is our representative for all future service calls

Really appreciated how straightforward Sully was with pricing—no upselling or surprises, just honest and clear. He was respectful of both our time and got right to the point. Super knowledgeable and took the time to explain everything in detail, answering all the questions my wife and I had. Great experience overall.

Great service! Jeff showed up on time (at the beginning of his arrival window), wore shoe coverings to protect my carpet from outside dirt (a big deal for me), checked my A/C, cleaned the outside of my unit, and let me know everything looked good. Given the recent hot weather, this was great to hear.

Excellent service as always. The technician, Keo, was courteous, professional, and efficient. I would highly recommend One Hour. I have been with them for years and service has been consistently outstanding.

Unfortunately, my technician wasn’t listed on the site. So I can’t mention him by name and I don’t believe he gave me his name. Can’t be too sure. Great service as always second time I’ve used this company hands-down the best. Technician was informative gave me every step that he was doing asked if everything was OK and to my liking. Worked with me around my animal and very clean will definitely be a repeat customer for the third time.

AC went out Wednesday night & we called them close to 10:00 PM. They offered next day to arrive between 8-10 AM. Service call that early was an extra $50, which we were glad to pay since the house was at a sweltering 82 degrees with high humidity & no air circulating. We were so glad to be able to call someone so late, speak to an actual person, and then have technicians out so soon the next day. We didn't know who to call, and were hesitant to try a company we didn't know, but couldn't be happier. Jose & Keo were great. They were very professional, made the repair, and we were back to cooling!

Jeff was great! Very knowledgeable and helpful. Also speedy installation for an ionizer.

The technician was prompt and extremely polite. Communication from the office was excellent and allowed me to best manage my time as well.

Jeff did a really great job! He was here within an hour of my call, thoroughly explained everything, and had our AC up and running quickly (thank god)! Will be calling again in the future.

Punctual, professional, efficient, and very friendly. I highly recommend One Hour Heating & Air in elk Grove Village. They’ve been wonderful since installing my new system eight years ago.

The guys were courteous, clean nest and knowledgeable. Gave us choices for location and helped us make smart decisions. They were great.
