• I paid roughly $180 for a maintenance check-up with SmartHouse Heating & Cooling—chosen over Hoffman Brothers due to their community reputation. The initial technician, whose name was Shelby, was polite and cleared our AC unit, which has had zero prior issues in seven years. Less than 24 hours later, we woke up to a loud noise. When I called, an emergency assessment was quoted with holiday/overtime rates due to the Labor Day weekend, and the technician I spoke with, Scott, recommended waiting until Tuesday unless we wanted to pay the service charge for overtime. With no way to know if the noise was of any concern, we decided to wait. At roughly 3:00 PM i got a text from our smart thermostat stating our home had been trying to cool for five hours and was unable to; climbing from 76 to 84 degrees upstairs and 82 downstairs. When I called back, Scott was the technician who agreed to come out. He was extremely courteous, but adamant about a $391 emergency charge just to assess the unit. This lack of flexibility to evaluate circumstances when a breakdown happens less than 24 hours after a tune-up is a severe customer service oversight. Discussing the process with Scott and reviewing online Reddit blogs, it is likely the capacitor testing pushed it past its capacity given its 7 year age compelled with their cycling off, testing, and cycling on of the system. If their processes and procedures can cause such issues, it should be made known before services are rendered. Lizz, an associate, later called with a polite apology and stated she was authorized to split the service and capacitor costs and waive the overtime fee. However, upon asking about their process to asses who was at fault, she lacked understanding of how maintenance protocols or testing are performed and whether their procedure could have triggered the failure. The owner, Mark, then called to apologize, admitting the incident was handled poorly, but he neither had any insight to their engineers processes and whether they could be at fault. Mark remarked, "I prefer to hire people more intelligent than I am," implying only senior technicians would know, so I requested a senior technician reply to this Google review as a explanation on whether their process could cause the capacitor to be pushed past its limits through powering down and a restarting surge. I am sharing this because a replacement capacitor for a unit such as ours costs roughly $15 to $25, and thus the bulk of the extra $391 charge is for services they likely caused in the first place. It also took him less than 15 minutes to replace the capacitor. Had I been refunded, I could see how this extremely rare situation was owned and taken responsibility for and builds trust. My review will remain up until I am refunded, however I understand they run a business and may not see the ethical boundary crossed here worth our future business or the cost to their bottom line. I would like to update this post with the fact that I have indeed received a refund. Overall, this shows me that the company does value my business, as well as shows clear, ethical practices that I believe are exactly what university residence value about their company. Although I do not agree that this was not the result of their service, they have made things right. We are our satisfied and I have reflected this in our review score. We will be open to using their company again in the future.

• We have a maintenance contract with Smarthouse and have been extremely pleased. During a heat wave our AC died and they quickly replaced our unit. Ryan and George were here for hours working in over 100 degree temps. They were a delight to have in our home and very competent. This is a rare company. 5 Stars plus

• I honestly can’t say enough good things about SmartHouse. They are one of the most impressive companies I’ve ever worked with in terms of the quality of their work, professionalism, patience, and customer service. I purchased a new HVAC system from them a couple of years ago, and from the very beginning the experience was outstanding. My building ended up having some unexpected issues that required additional work, and the SmartHouse team was incredibly helpful, patient, and accommodating throughout the entire process. They went above and beyond to make sure everything was done properly. The owner is probably one of the most honest, customer-focused people I’ve had the pleasure of working with. It’s clear that he genuinely cares about his customers and takes great pride in the quality of the company’s work. That level of integrity and commitment is incredibly rare these days. What impressed me even more was their continued support after the installation. Even while I was overseas, they were responsive, helpful, and supportive whenever any issues related to my home’s AC came up. Knowing I could count on them, even from another country, gave me tremendous peace of mind. I’ve truly felt like more than just a customer—I was treated like family. Companies like SmartHouse are hard to find these days, and I’m incredibly grateful for everything they’ve done. I wholeheartedly recommend them to anyone looking for an HVAC company they can trust. You won’t be disappointed.

  Patty K.★★★★★

• Shelby came out to do our AC maintenance. She was on time, friendly and very efficient. She was very knowledgeable and checked our upstairs and downstairs units and then checked the condensers outside. She did a great job (on a very hot day-UGH) and everything is working great. Having AC these days is such a blessing and also to have a reliable source for maintenance and repairs. Thanks again.

• Had Smarthouse provide a quote after my friend referred me to them. Received 3 separate quotes for a replacement AC/Coil from different companies all around the same price range however Smarthouse was a 2-stage system and the others were only a 1. Marc was great to work with, helped me plan out options and also worked with me on quoting the Ameren Pays program to help subsidize/loan part of my new setup across future Ameren bills. My installers were great and efficient. They did a fantastic job of sealing everything inside and out and cleaning up after themselves. Stephanie and Kaylee in office helped with follow-ups and also did all of my backend work for warranty setup, and form prep for Ameren pays. This was probably my biggest surprise and was an unexpected relief. Everyone through out the process had excellent service, and response time was top notch! Summer Update - 7/1/26 - it’s been in the mid to high 90’s the past few days. I used to think my house just couldn’t be cooled down enough bc it’s old and all brick with no shade…but I was wrong. My new unit from Smart House consistently keeps my house at a nice 71. Thank you all again for the great service and keeping me nice and cool!

• I could not have been happier with SmartHouse. They did an incredible job relacing my furnace in my attic. From the owner, to the admin staff to the installers everyone was very professional and easy to work with. Their work is top notch and they are honest people. An overall excellent company. Shout out to Ryan and George who did the bulk of the installation work. It was not an easy job but they made it look easy. Highly recommend this company.

• Recently, the first-floor zone of my HVAC system stopped cooling properly over a weekend. I left a message with SmartHouse Heating and Cooling's answering service, and Bob Going called me back shortly afterward. I have worked with Bob for several years and have always been impressed by his knowledge and professionalism. In my opinion, he is one of the best boiler technicians in the St. Louis area. After discussing the symptoms over the phone, Bob quickly diagnosed the issue and provided clear instructions on how to address it myself. I followed his recommendations, and the problem with my air handler was resolved. The first-floor zone immediately began operating as designed. What impressed me most was Bob's integrity. He could have easily scheduled a weekend service call, but instead he took the time to help me solve the problem over the phone, saving me both time and money. That level of expertise and honesty is hard to find. Thank you, Bob, for your know-how, responsiveness, and outstanding customer service. SmartHouse Heating and Cooling continues to earn my trust and recommendation.

• My AC was not cooling properly. I able to schedule an appointment the same day. The staff was friendly and transparent when it came to costs. I called today at 8 AM, and the AC technician stopped by shortly after and got everything taken care of. My house is now cool and ready for the summer heat. Thank you!

• Tim came to gather info for a ductless mini split system for our upstairs. I already know that no matter how low the quote, we won't be going with SmartHouse... he closed the panel door on the breaker box, not ever considering that it might be open on purpose. The door is stuck when closed and the front cover of the panel has to be taken off to open it again. It created about 10 minutes of work, not too much but just enough to annoy me. Tim, that is when you blew it. When you decided that you know it all and shut that door. Don't even bother sending a quote. Edit: The response from whoever is just like Tim: verbose, condescending, and insulting. Tim is a glorified salesman with a tape measure. He lectured us at length about insulation like we had never heard of it and wasted five minutes of my life comparing an AC unit to a tire. Good god man, learn to be concise! People aren't idiots, we don't need a lengthy explanation of how using an air conditioner will wear it out.

• I've been using SmartHouse for a few years, and they're always professional and informative. This spring, I had made an appointment for a maintenance check, but when the weather station predicted 90s by the end of this week, I called the office back. Kaylee offered a 5pm appointment, and said she would let me know if an earlier time came available. It did, and (one of my favorite techs) Bob came out. It turned out to be just a thermostat gone bad. I chose to replace it with a smart one, something I'd been wanting to do for some time. He helped me set up the account and my preferred settings. Now I can fact the weekend heat with a smile!

• Marcus was great! Checked AC and furnace. Replaced part in AC. Very personable and knowledgeable.

  Kelly T.★★★★★

• I had two breakers replaced in my breaker panel. I had new fan systems installed in my upstairs and my downstairs toilets. This necessitated the installation of venting to the outside. All of this work was performed professionally, and the clean-up after the work was concluded was impeccable. A master electrician and an apprentice carried out the work and I am very pleased with the results. The work was not easy, and took 7 hrs total time.

  Mark E.★★★★★

• Zach was really great! Very happy to share his knowledge and expertise every step of the way. I also appreciated that he was equipped with those little booties to put over shoes to keep your home clean. Thank you and looking forward to using this company again!
