Prompt, professional, honest, and fair. Had central air replaced in Oct 2025. Had a small problem with drain that backed up and fried the capacitor. They fixed it at no charge under warranty, admitted the mistake and fixed it. They could have easy contrived a reason it failed and charged us. This is how you make a custom for life. Thank you Trenton!

Tyler came to my condo as I have a particular small compacted hvac system. He has experience working with national comfort as many do not. The last guy who came to resolve my issue just put easy seal on it because he didn't want to do the work. Tyler diagnosed my problem then gave me a resolution. He was honest, fair, and professional. I can't say enough good things about my experience and look forward for them to help with future repairs!

Our heating system went down. Sales responded immediately. Installation staff was great! Luke and Jason removed the old unit and installed the new one. Steve worked on some duct work. Gary also contributed to the installation. Luke and Jason first thing they did was put down floor covering. Very polite and worked the entire time. Took the time to explain a new digital thermostat. Answered all our questions. Very professional! Thank you, The Ransom's

After the hottest day of the year, thus far, 6/18/21, my A/C unit decides to stop working. After a miserable night of extreme heat, I called Kirkwood Heating and Air Conditioning around 6:30am on a Saturday morning. Their technician, Kevin, arrived at my home in about 40 minutes. He was able to get us squared away in no time. Because of the circumstances, I wasn't really worried about the price, but the fact that Kevin came out so quickly, I would recommend their services to anyone. Thanks Kevin!

Collin and Jeff were assigned to install a new heater at my house. Not only did they do the job efficiently and professionally, they were also personable and cool to talk to. Care was taken on little things like using drop cloths to not get the house dirty, meticulous post-installation cleanup, and a crash course in operating the system and reading basic codes from it etc. Basically, KHAC and its people in the field rock.

Chris was great to deal with and was very informative. He walked us through multiple scenarios with advice to which units were recommended and - are you ready for this- his recommendation was NOT the most expensive way to go, and then, the other two new unit install guys were perfect! These guys are very knowledgeable, professional, and friendly people in every facet, thanks guys/gals for making this as convenient, quickly installed, and comfortable in St. Louis smack dab in the middle of June!

Great job, KHAC! Our new furnace was installed yesterday. The furnace we ordered and they brought with them was damaged. They were not able to get the same furnace quickly so they upgraded us for free and were still able to install that day. Thanks for being so accommodating!

Kirkwood Heating and Air Conditioning went out of their way to diagnose my problem and get me back up and running within a few days. They worked after hours to take care of my system and made sure I had AC before I was hosting a party. Very courteous and professional. So grateful and recommend them highly!

Huge shout out to Kirkwood Heating and Cooling. After being out of town this weekend we come home to no heat. They were here , on a Sunday within an hour and spent two hours fixing our unit. Doug with Kirkwood is the best! Huge Thank You!!

Always a quick response! Very polite and knowledgeable. Great value. Chris seems to be "our" heating and cooling guy, he's the one that always comes to our house. We do schedule maintenance spring and fall. Three (?) years ago after our check, (one of the VERY hot summers) our upstairs AC had problems, they checked it, had leak and was low on freon. It was "fixed" to work for that day/night. A new one was put in the next day, if not, the next. They don't try to push anything or sell you more than you need.

My furnace recently stopped working on of course, a Saturday. After researching HVAC company's on-line I called Kirkwood HVAC hoping I could get someone to come out on Monday. I was so happy when Tyler immediately called me back and said he could be out within the hour. He arrived in about 45 minutes and had my furnace running almost immediately. Even though my furnace was super old I told him I would probably not be ready to replace it for another year but I would be happy to receive a quote from them for a new one.

I received a quote the following Monday and went ahead and set up the installation for the new one. I was quickly sold on this company's expertise at what they do and their exceptional customer service!

Today April 26, 2016 Kirkwood Heating and Cooling's installers Mike and Jeff installed a new air conditioner and coil at my daughter and son in laws house. They did a great job. It was very neat and clean. They were both friendly and installed the equipment promptly. From the day I made the service call to the completion of the installation, everything went very well along that came with a good price. I would recommend this company to anyone in need of service and/or installation of heating and cooling equipment.

KHAC has cared for our heating and cooling since we moved to Kirkwood about ten years ago. I think Chris has been maintaining our equipment from the beginning. His service, attention to detail, neatness and personality speaks volumes as to the quality of the company he works for. His longevity with KHAC reinforces the adage that great people stay with great company's. I've trusted them to keep our equipment safe and functioning efficiently and they've never failed us.
