HVAC reviews in St. Louis, Missouri

This was my first time using SmartHouse and I chose them because the were an authorized service company for our unit and I could not be happier. He arrived at the appointed time looked at our damage and said he figured an hour or so to fix it. He went to work and completed our repair in half that time. I would recommend SmartHouse for any heating or air conditioning repairs from now on. 👍🏻

Peak emergency calls after a snow storm. We called first thing in the morning and it was fixed by 2pm. Jay was beyond great!

SmartHouse is a terrific heating & cooling company! They are locally owned, really honest, have very fair pricing and their technicians are extremely knowledgeable. This was my 2nd time calling them....and I was not disappointed! Excellent service, pricing & workmanship...just like the first time! I can't recommend them highly enough! : )

We just had our first experience with SmartHouse, and I feel so relieved! Nick H., our technician, was knowledgeable and kind and I would recommend him and the team to anyone looking for pros they can trust. It was an easy decision to become members! Thank you so much!

Shout out to Zack from Smarthouse for spending several days in unfavorable conditions of extreme heat and being in our attic to diagnose and then make a major repair. Zack is the reason we will continue to use Smarthouse for all of our HVAC needs. Appreciate his honesty, time to educate me on the issue, and expertise.

5 Stars for Zack S!!!! He solved my overwhelming dust problem. He found the source of the problem with an intake space filled with concrete chunks, dust, and debris. Thank yo so much SmartHouse for this employee!!

Great experience from start to finish. Very responsive with great communication beginning with the initial quote by Marc all the way through the install that was performed by Stephen and George. The entire team was knowledgeable, friendly and truly seemed to care about our satisfaction. Highly recommended.

No one wants to need HVAC! Especially in St Louis when it’s over 100 degrees. SmartHouse was awesome. They made it over quickly and provided a reasonable bid to do the work. They brought an individual cooling unit to use while I was being installed. They installed my new system and got everything working quickly and they clean up after themselves! The guys who did the work were thoughtful about the little things like my dogs and blocking the driveway.
It was not a situation anyone wants to be in - when you are I recommend SmartHouse

Very pleasant person who set me up with an appointment. Texted when the technician was on the way. Marcus was prompt , courteous and knowledgeable. He came to install a smart thermostat and in doing so,
identified a previously unknown issue and fixed it pronto. He also gave me information about A/ C systems that was extremely helpful as we will be needing one soon. Highly recommend SmartHouse Heating and Cooling.

Marc and his team are true professionals and Steven’s craftsmanship is incredible. We had some unique challenges in our older home and they took the time to develop a plan that made sense. We replaced two units with them and had both return and supply duct work done and our home is quieter and more comfortable than ever. Thanks guys!!

We used SmartHouse to replace our HVAC and had a great experience. They quickly scheduled a time to give us a quote, answered our questions, and did not try to upsell us. Had some good discounts we were able to take advantage of as well. The work was completed quickly and professionally. Will definitely be using again!

Thank you for the service! I called on 12/4/25 and they sent out Technician, Ryan the same day. I am giving Ryan and the company this review because Ryan went above and beyond to repair my boiler issue. He was knowledgeable, concerned and very pleasant. He answered and gave input to my questions. I highly recommend this company and Ryan the technician to handle your heating & cooling needs.

SmartHouse Heating and Cooling is amazing. Starting with Marc the owner, he came out and was extremely knowledgeable and down to earth. He went the extra mile to explain the technology and equipment. The install team was very courteous and respectful. They were able to move quickly and efficiently to install a complex system. I am excited about my new system and can’t wait to take advantage of all the efficiencies. I can’t recommend SmartHouse Heating and Cooling enough.

Had ongoing issues with the heating and air unit, partly with cheap workarounds (substandard parts), and some due to a leaking vertical flue (also a cheap workaround). Ended up getting a new system. Started with the tech who tried to resolve the issue but due to the re-occuring problems (noted earlier), we had a consultation to assess our current set up. Turns out the system was not optimized for our home (unit was trying to pull in more air than what the house could handle), so a more appropriate system was recommended. Installation was completed in a day which also included a new horizontal flue. Techs Ryan and Jay were courteous and friendly. The home was left clean with nothing left from the old system. Ryan took the time to explain the new system, helped set up the app, and addressed any questions. Very satisfied with the work and looking forward to the working air!

Recently had heating and cooling installed by Smarthouse. We had a great experience from the initial consultation to the installation. Marc came to our home and spent time reviewing our current system and explained different options. Other companies that we considered didn't come close. We felt confident in using this business.

John was excellent. John responded promptly when I stated my concerns. To summarize John provided me with exemplary service.

The crew did an awesome job. They came out with four or five guys and worked tirelessly to install our new air conditioner and furnace. They also installed two smart thermostats and program them for us. In addition, they made two separate trips to optimize the smart, thermostats, free of charge.

Great company and I would give them my highest recommendation.

Marc was very knowledgeable about the heat pump system I wanted to be installed. The team went out of their way to make sure my wife understood the app and how to control the new system. They installed a properly sized return air duct and took their time making sure everything looked good as well as performed flawlessly. I highly recommend you give them a chance you won't be disappointed.

Amos was a very thorough technician. He was very personable, and took time to explain the the results of the furnace inspection. Appreciated him very much.

Great company. Dispatch fee is $120.00 ! They wont volunteer the info when you call them so just confirm. Doesn't matter if its a minor or major issue.

Everyone that I have ever talked to at SmarHouse has been very professional and personable. The techs not only know their craft but also are curious and professional. Matt, Ryan and Bob installed a new HVAC unit in our condo. It was a full-day effort and I was working from home. I had zero inconvenience and they cleaned up before they left. Super happy with the job and the service. I'd recommend them to everyone.
