The Trusted St. Louis HVAC Contractor

Excellent service and thoughtfulness!

Great technicias. Wonderful work. Highly recommended.I

Everything is professionally installed . Great system

Zack was great, explained the problem and fixed my furnace to my satisfaction. Neat, courteous and very personable technician.

Really appreciated the quick response and resolution of my HVAC issue. I’ve lived in three different buildings; SmartHouse (or its predecessor) has managed the HVAC systems in all places. I feel I’m a pampered client!

A very competent and personable technician was dispatched for an A/C issue in which he quickly resolved.

Excellent service and attention to detail

Decided to be proactive and replace my 24 year old central air conditioner before it quit during a heat wave. SmartHouse sent out Specialist Tim the same day I called. He answered all my questions, took measurements, fully explained my options and gave me quotes on 2 replacement models. We accepted one bid and were able to schedule the install for the very next day. Because our appointment filled the last opening in their installation schedule, Tim gave us a sizable discount. Ryan and his install crew arrived on time the next day, explained everything, completed the install and gave me another discount for paying with a check. It was a very easy, quick, and professional experience. Thanks to SmartHouse I now have piece of mind for many cooling seasons to come.

We have used this company for years. Always so nice to deal with employees and service is exceptional.

The technician Bob was very thorough with the inspection. He was able to explain everything clearly and point out the issues.

We had Troy Wilson out to our house to check our AC and heating unit. He was knowledgeable and provided great information on what we need. He very professional in his deamnor and respectful of our home.

Marcus, went right to the source of the problem and got our humidifier running again. The staff at Smart House provides great customer care.

The technician was professional and did a great job despite a difficult access to the condenser. All of the people I have worked with are highly competent and willing to take the time to find a good solution to problems rather than the most expedient. Locally owned small business that charges a reasonable rate unlike companies that routinely price gouge. I highly recommend SmartHouse.

Nick did a great job explaining what happened to the air conditioning unit and what was needed to repair. He took the time to update me on my AC unit.

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.

Really impressed with the service we received, very friendly and quickly diagnosed the issue. Technician came out at 7pm to fix our furnace and had it up and running in no time. We will be using SmartHouse for all future HVAC needs.

Smart House was great to work with, quick and courteous communication, reliable and fair on price!

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!!

SmartHouse Heating and Cooling were on time, efficient, and delivered a solution during our service call. We have been happy with their work and professionalism. They are top of our list for our heating and cooling needs.

Great customer service. Very professional. Will recommend to anyone who needs furnace, Ac system. + we also replaced water heater with the plumbing company they referred, and they were great as well! Thanks for your great work

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 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.

Always wonderful, kind and helpful.

Jay is very friendly and worked hard on my house. I have no complaints about him. But right after I cleaned up all the mess due to the attic work (Jay offered to do but I told him I would do), the system failed again. I am certainly very frustrated. The system is only two years old. How can it have so many problems when it is supposed to last for more than l0 years.

Service was prompt and friendly.

Frank is the best technician I’ve ever had.

Nick did a great job with coming out and accessing our situation. He was knowledgeable, professional and answered all of my questions. I would use them again in the future.

Awesome job. The technician was truly a blessing

Super friendly, quick turnaround on install. Great prices and warranties:

Scott resolved the problem and informed me about what might be needed. He did a fine job.

We called Smart House for a second opinion after another HVAC company told us the circuit panel needed to be replaced for $900 or we might consider replacing the entire furnace. Smart House got to us the same day we called them, found a short in the wiring to our humidistat, rewired a few wires and got us up and running in an hour. Their technician saved us a boat load of money. Thank you Smart House for your honest and fairly priced service!

These guys are friendly, professional, and extremely knowledgeable. Strongly recommend.

"Cool Jay" showed up on time, was very polite and professional. I was referred to your company by my aunt. I am quite pleased and confident that you guys are our new service technicians. Thank you!

These guys are the best! They work and care for our house as if it was theirs.

The serviceman Scott was very knowledgeable and friendly and took care of my boiler. I will definitely use them again. Price was reasonable also for what he had to do.

Smart House arrived within 24 hours for a non-emergency call. They charged me $30 less then quoted and was professional throughout the process with update calls and a great disposition. Thank you!

My HVAC Technician Nick came earl than the scheduled appointment time. Nick was tremendously helpful at diagnosing the issue and gave me great advice on how to keep my HVAC running smoothly moving forward. I definitely recommend this company. I was satisfied with my services.

Great company and technicians! Spend the time to walk you through what they’re doing and give honest advice and recommendations!

SmartHouse beat the competition with a promt return call after a busy holiday blistering cold weekend. Nick H provided an accurate time of arrival; he consulted me and resolved my heating problem swiftly. Nick is highly professional and got the job done right. Thank you!

The technician was very polite and friendly. Explain what he was checking and told me what was the problem. Will recommend to family and friends.

Smart house heating and cooling did a great job repairing my furnace the technician was polite and professional and worked digitally to fix my problem

Our HVAC system was replaced by SmartHouse in the late-summer of 2023. They serviced the units earlier last week as part of a pre-paid semi-annual maintenance program. Yesterday, we noticed the upstairs unit wasn’t working. Even though it was a holiday weekend, they dispatched an on-call technician to diagnose and correct the problem before the upstairs got too cold. We couldn’t be happier with SmartHouse!

Marcus was very helpful and knowledgeable.

Jeremy was my technician we started off a little rocky lol but he got the job done in a professional manner. I would recommend him

Like this Company a lot. They installed my system 10 years ago and it didn’t need any major work until this year. They are responsive and efficient.

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.

On time, explained everything, found best option for our situation, installed new furnace quickly. Long relationship with Smarthouse has never disappointed.

Very professional and knowledgeable. Zack kept me informed the whole time and asked if I had any questions. I would definitely recommend them to others.

Efficient, thorough, and very helpful service. I definitely recommend working with them and will be using them again in the future.

Outstanding service, very knowledge tech, I am very impressed and pleased.

SmartHouse Heating & Cooling did an excellent job replacing our HVAC system. From the front office to the installation team, SmartHouse was professional, responsive, polite, efficient and a terrific value.

Smart house is rhythm with smart people, who know how to win and keep customers. Most of all they a very professional business. Wendell

The Installation of a new furnace and AC unit was accomplished with professionalism, competency, and the highest level of craftsmanship. They had to first take out a 25+ year old system, and obviously all of the various lines, pipings and sheet metal ductwork we’re not about to line up with the more modern, compact and advanced system. But they reconfigured everything beautifully, on budget and on time. I recommend them highly.

They're proving to be pretty good

Bryon was most helpful. He was very knowledgeable.

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!

Good company. I've been using them for over 25 years

Great job, Zach! Thank you! Mila

I have used Smarthouse for several years for my business and home. I have tried other national and local companies and this is the best. The technicians go above and beyond, the office staff is awesome, and I appreciate the thorough and practical explanations. I found them on google and tried them out because they were well rated and another local place was falling short on service and responsiveness. I am glad I did. Smarthouse has delivered time and time again with the quality of their service. As a business owner (and homeowner for that matter), having a company you trust is such a big deal. This place is a winner.

Very professional service

Professional and knowledgeable. Earned my confidence and a call back!!!

The employees of SmartHouse are prompt and courteous. A couple of years ago we purchased our heating and air conditioning units from them and have been very satisfied.

So glad this is our go to hvac co. Always pleasant experience with their reps.

It's Saturday. I'm trying to install a new smart thermostat and blew a fuse. The technician was WONDERFUL and so helpful. They were faster, more helpful, and their rates are less than the company who installed the unit for the previous owner. I'll be calling SmartHouse for my HVAC needs from now own. Highly recommend! Thank you!!!

Great guys, great service they showed fast on a Saturday. Would highly recommend

The tech fixed our capacitor issue with no problems. He was very professional and top notch. I found my HVAC company for the future!

I was really impressed with the Technician, Jay. He diagnosed the problem and got my AC up and running! He was very professional and patient with me and my many questions!! thank you, Jay.

Fast response to emergency. Work was completed in record time.

My tech Marcus was terrific, honest, educated me on my system, and worked without wasting time. I look forward to my winter maintenance with Marcus this fall.

The team at SmartHouse are very knowledgable. What's more, I'm extremely impressed with their customer service. Our new Water Furnace geothermal unit was faulty, and recently failed completely. SmartHouse really jumped right to getting a new unit installed under warranty, as well as providing mobile AC units for our house until the new Water Furnace was ready. I highly recommend SmartHouse.

My house AC had a miner problem. The company quickly solved the problem.

I’ve gone to SmartHouse for home upgrades, regular seasonal maintenance, and now a repair involved in an insurance claim. They have been extremely responsive, easy to work with, and informative to me, the homeowner. Great company

I am so pleased with the service I always receive with SmartHouse heating and cooling company. I trust them with any work if needed on my furnace/ air conditioner. I would recommend them to the whole WORLD.

Smart House is the best! Great and timely service. The staff knows their “stuff”!! Fair pricing for the excellent service they provide. We have been delighted with Smart House.

I called Smart house for a second opinion on some thing and boy am. I glad I did. They were able to save me thousands of dollars.

They were very prompt. Really appreciate Marc who clearly answered our many questions and appreciate his staff Stephanie, Liz and others who helped us with financing and scheduling. I fully recommend and trust this team.

Time for a check and clean. Gotta keep the systems going. Very efficient and timely service .

I've used SmartHouse for years and recommend them wholeheartedly. They've always resolved my issues quickly and for less money than other contractors. I plan to entrust them with a major renovation of my AC system and furnace. They strike me as honest and efficient. I've only had great experiences with this company.

Top notch company with top notch service. Highly recommend!

He was professional friendly and fast. Didn’t try to add stuff or spend money we don’t really have. Honest man . Will definitely call again for any repairs. Great company

Ryan and his crew did a great job with the installation. Duct work was top-notch. Even helped with replacing a broken gas shutoff valve on my water heater while they were there. Very impressive!

I couldn’t recommend SmartHouse more highly - they are thorough, reliable, and completely trustworthy. Special shout out to Bob Going, the best!
