The Trusted St. Louis HVAC Contractor

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

Marcus was very helpful and knowledgeable.

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.

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

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.

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

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.

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

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!

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.

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

Very professional service

Great job, Zach! Thank you! Mila

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!

Very friendly, knowledgeable and highly professional service! 👏 👏!

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

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.

Showed up on time, gathered information and started the diagnostic . Found the problem , corrected the issue. I was kept abreast of every step taken to get my unit up and running . I truely appreciate their professionalism .

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.

Always great service

If you want the very best in service, SmartHouse has the very best people that know what they are doing. No short cuts here. They are on time or a little early for appointments.

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.

Awesome company and service!! Very impressed with their willingness to listen to our needs and situation and to tune their recommendation accordingly . We replaced our A/C and furnace - no issues. 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!

Amazing company to work with. Everyone is friendly and accommodating, it shows that they care about their customers. Will recommend this company to anyone who will listen.

Great service. On time and professional. Technician was very friendly and knowledgeable

A great experience in all respects. Marc came out and did a thorough assessment of our needs. Not the typical "let's sit down at the kitchen table" sales pitch. The proposal came later that same day, and Marc responded promptly and thoroughly to my follow-up questions. The day of the installation went smoothly. Marcus, George and Bob arrived exactly on-time. All three were courteous, professional and efficient. The installed work is neat and tidy and we couldn't be more pleased with our new HVAC unit. I highly recommend SmartHouse.

Today had a non-stop screeching emanating from the furnace and Marcus was able to stop by and figure out what was happening, then fixed it!! This company and their staff are wonderful, kind, professional, and very responsive!! Best company!

Smarthouse recently replaced an HVAC unit for us. We had a fantastic experience. They were very professional and did a great job. I highly recommend Smarthouse for your HVAC needs.

Great product, great crew!

Great company, good communication, detailed quotes, and strong knowledge of modern eco-friendly heat pump systems - and did a helpful energy audit of my old brick home too. Strongly recommended!

Been working with SmartHouse on various home improvement and remediation needs and they have always been helpful, professional and met our needs.

Great company! From scheduling, estimate, to installation every individual was prompt and courteous. Very happy with our new HVAC system. We continue to use SmartHouse for maintenance and have never been disappointed. They will have our business for any future needs!

The workers did a fantastic job. Whitney also cleaned up after their work. I highly recommend SmartHouse.

Very friendly was very upfront with what we needed . Would use them again if needed to

Came out on New Year’s Day within 30 minutes of calling. Quickly identified the problem with our furnace and had it fixed in no time!

We returned to our house about 4pm yesterday (12/31/23) to find our furnance not working. SmartHouse answering service person was very polite and helpful, promising a call from a service technician within an hour. Scott called in about 30 minutes, we discussed the situation and he said he could be at the house in about 30 minutes. We both had guests due at our houses in a few hours for dinner. Scott was professional, knowledgeable, and polite as he diagnosed and resolved the issue. We could not be more pleased with the manner in which this issue was handled and resolved.

Awesome customer service from the office to the technician

I had a great experience with the technician Bob. He was courteous, knowledgeable and worked quickly. He swiftly had our boiler furnace back up and running during that horrible cold. This was my second time calling SmartHouse. My first experience with Luke, he was why we called the second time. Knowledgeable professionals with great sense of humors. Would highly recommend.

Quick response and friendly.

Great team. My house is 100 years old, and the electric system might be older. I’ve had these guys come out on Christmas to help me and my family, and they were there and fixed it, and were nice to boot. They do what they can, and they don’t invent problems for you to pay to solve. Very solid business, would use them again

Service was great! Explained everything that was going on, made suggestions that were super useful! Very happy!

Service 24/7 The technicians are personable, knowledgeable and friendly.

The. guy was very helpful acknowledgible. They're prices were extremely fair and Reasonable. I will definitely call them again if I need them.

We had Smart House Heating and Cooling visit us in early Fall due to one of our outside units had already frozen over and we had conerrns going into Winter. Techs advised older unit should be replaced but we opted to get one more winter out of the unit. The unit hard frozen over in January and we needed a replacement ASAP. Tim came out and said he could help us and get job done before the next hard freeze came through. The crew arrived and were efficient and professional. The temperature dropped all day and the crew worked all day inside and outside for us. Great job and Thank you for all the work. We would recommend the company and crew any day.

The Smarthouse folks have been nothing but splendid! Super responsive, respectful, and knowledgeable. I feel like they take my questions seriously and ensure that I understand all thats going on. They understand each rebate and tax credit and handled it for me. I have only had extremely lovely experiences and recommend them to all my friends.

The best in the biz! Called late in the evening for a broken furnace and Ryan was out in a couple hours. He diagnosed and fixed the problem in about 45 minutes and I had heat again. Highly recommend!

He was adorable and , polite and business. I'm at a loss for words. I must keep this company and tell it on Facebook

My boiler went out with the Polar Vortex on the way. They sent a service tech out within an hour. Problem fixed! Definitely recommend!

SmartHouse has been responsive, professional, knowledgeable, honest, and considerate every time we’ve worked with them on diagnosing problems and repairs. We recommend them highly, and will definitely use them when we’re ready to replace our system.

Luke was very easy to talk and walked through the systems in our new house, 🏡. He was patient and did a thorough job. SmartHouse also called and arrived the next day for a maintenance call. Amazing! Will call back anytime they are needed. Everytime.

The service man is very nice and professional!

The best! Have been using them for years.

Excellent. My furnace died on Saturday. Contacted SmartHouse on Sunday. They called Monday morning and set up appt for Monday afternoon. Great consultation; good options; very good price. New furnace and AC installed Tuesday. Had a couple of problems but they worked through them very effectively. I am a very satisfied customer and would gladly recommend them. They did good work; cleaned up afterwards; answered all my questions; very professional. I’d give them a 10 out of 10.

Knowledgeable, professional, courteous and longer warranties.

The technician was courteous and helpful thank you

Great service. Fair price. Professional and friendly technicians

Great advice and super trustworthy

Technician Scott was very thorough.

Another great visit from Smarthouse, very polite, respectful of my home, covered his shoes! Did his job, and told me everything looks good, and left!

I have been frustrated with my HVAC people for years. Finally had it and put out some bids and Smarthouse was not only the best bid but sent genuine, experienced maintenance adults to deal with us. They didn't try to oversell us on a new system but gave us good information to help us decide. Office staff has also been great. Looking forward to the regular service.

On time and professional.

Technician was knowledgeable and friendly. Explained what the problem and how he fixed. Priced seemed reasonable

SmartHouse should be at the top of everyone's list when considering anything related to HVAC in their home. Their staff are experts in advanced and traditional HVAC technology. They take a diligent approach to every project, ensuring that systems are right sized for the home, rather than mindlessly doing a one-for-one replacement like some installers. Using building science, mechanical engineering, fluid dynamics, energy engineering, and thermodynamics to guide their recommendations, you can be assured that the options presented to you are well thought out. All staff were very professional, courteous, and responsive. Our old system died during the week of August 21st, 2023, when temperatures were soaring above 120 degree heat index. They were able to replace our 23 year old system with an ultra energy efficient Daikin heat pump within 2 days! All at an exceptional value. They have my absolute highest recommendation.

Writing a thorough review because it is what helped me to pick this company, and maybe it will help reassure others they are making the best choice. Earlier this year, my parents' AC started malfunctioning in the house I grew up in. With much else on their plates, I decided this was one thing I could help them with. With a decidedly subpar experience with a company sent out by their home warranty, I did some research and made a short list of local companies that seemed to have the best reviews. Smart House was on that list, and due to their clear pricing for a diagnostic evaluation earned our initial business. Matt came out to the house and did a thorough workup, explaining in detail that our system was low on a type of coolant that was expensive because it was no longer made, and that even refilling it wouldn't guarantee that it wouldn't leak out or that our aging system wouldn't go bad from something else shortly after. He took time to answer many questions in a way that was clear and understandable. Without any pressure whatsoever, he went ahead and took measurements for a potential replacement just to make sure things could proceed as quickly as possible when we decided what we wanted to do. He further answered questions about what to expect with newer units and what it would entail to replace it. My parents then independently got a couple more quotes on their way to deciding on an AC/Furnace replacement. By all accounts, Matt was the most professional of the specialists they encountered and SmartHouse and their bid were the most clear as well as best value. Even as we proceeded, the office staff was top-notch. Jane was able to answer questions as well as help navigate that while things started under my name, it was for my parents' house and to get their sign-off as well. They were able to fit us in for the replacement faster than expected. Matt and Luke replaced the furnace and AC in a full-day job. Even things we had been worried about were already well thought out and addressed- for instance, the furnace needing a new in/out vent that we didn't previously have which they placed in a discreet area with an appropriate cover. All this was done in mid August, just in time for our brutal heatwave, and I can say confidently the new system tackled it with ease. From beginning to end, SmartHouse was an extremely professional and friendly company to work with. Every step of the way things were explained with ease and never once did they make us feel pressured. They are a company I will use on my own house when needed and gladly recommend to others.

Excellent timely service .....as always Bob and Nancy Wagoner

Smart House did an amazing job on my complete HVAC replacement. They were easy to work with and responsive to my questions. I would highly recommend for anyone looking to have their system serviced or replaced.

Luke was very professional and explained in detail what he was going to do.

SmartHouse was well-recommended and well-reviewed, so I was happy to get them out to take a look at my system. The tech was very knowledgeable and picked up on issues that another HVAC company missed. I was promised a quote in 24hrs. A few days later, I emailed to check on the status and never got a response. Two phone calls to the main office were met with "we will look into this and get back to you shorty," but they never bothered to call back. So in the end, this has just been a big waste of time.
