Updated 4/25/2025 review: would be delighted to change this back to 5 star, but no way at this time. 1 reply since 4/14. No followup; can't coordinate with roofer to actually install A/C unit to my home (each says they will, but neither does), months after it was craned to the roof. Only half the house has A/C, and the single unit working cannot cool the whole thing below 76°. Horrible in 80+° heat. Need relief, and very much not getting it here. Very unprofessional and unethical.

Marcus is great. He's serviced my house several times for both AC and furnace maintenance. He's very knowledgeable and thorough. Takes time to explain things and answer questions. Also offers suggestions, but doesn't pressure you. He's very efficient. Appears to be an honest HVAC tech and good guy.

We found SmartHouse almost by accident while looking for solutions to what turned out to be botched previous AC installation by a much bigger and more established company who we had trusted to do a decent job. Instead we ended up with a system that wouldn't cool the house. Smarthouse first correctly diagnosed the problem, then fixed it, and advised us on how best to heat and cool our 100+ old house. We now have a service contract with them for regular maintenance and they recently installed a mini-split for us. Their techs are great. Just the sort of people we would feel comfortable leaving alone in the house to finish a job if necessary.

I was very pleased with SmartHouse heating and cooling. Easy to schedule appointment for bid, energy auditor arrived on time and was very professional/courteous, bid amount was reasonable, work was done within one week of accepting bid, and the crew did a good job of ensuring the insulation was at the correct depth throughout the entire attic. At my request, they took several pictures to verify their work and I was completely satisfied. Would definitely recommend this company.

From the initial visit with Marc to the installation with Stephen, everything went smoothly. The system we purchased is a highly technologically advanced system and we are extremely happy with it. The service provided by SmartHouse was professional and courteous in every way.

Bob was scheduled to be out between noon & 2, and called just before 1:00 to let us know he was 20 minutes away. He arrived with gloves & mask, and quietly worked on our combo boiler/water heater and AC/heat pump to do the annual maintenance. He provided a useful recommendation as an alternative to a more expensive remedy for a calcification issue, and left me confident that he was technically proficient and worthy of our trust.
Response from SmartHouse Heating & Cooling
"Thank you for taking the time to post about your recent maintenance visit with Bob. We're happy to know you're pleased with the service he provided and appreciate the trust you have placed in our company. Welcome to the SmartHouse family! We look forward to continuing to serve you."

Luke had modern tool that detects gas odor. He was able to find the small leak and repair it. He was very professional and friendly.

Obviously we have taken this information back to the company that originally installed our insulation, with mixed results so far. Throughout this process, though, SmartHouse has been extremely professional. They have now done three different inspections, and we ended up having them complete the insulation work because the other company did a perfunctory job when they came back to "fix" their own problem. Tim, in particular, has been very pleasant to work with and has taken the time to answer many of my questions by phone and e-mail. Each time they inspected our attics they took multiple photos to document the state of things both before and after their work was done. We selected SmartHouse based on their positive reviews, and after working with them I can understand why they are reviewed so highly. I would not hesitate to hire them again for any future work we might need.

We hired Smarthome to insulate our attic. They were not the lowest bid, but their expertise, particularly about the various insulation options, convinced us to go with them. And I am so very glad that we did. Not only did they do everything we expected in terms of insulating our attic, they noticed that the duct work in our air conditioning system had not been properly sealed. We had been wrestling with the unit's inability to cool our house for years, and our regular HVAC provider told us that this was the best the system could do. In fairness, we have an old house and a complex air conditioning set up. Smarthouse both diagnosed the problem and undertook the necessary fixes for a very reasonable price. As a result our house is markedly cooler and our electrical bill has come down a bit. This is a great company. They know what they're doing and they genuinely seem to care.

The technicians are so nice and helpful, professional, and punctual. They've maintained my hvac for the three years I've lived in this house and all runs smoothly.

They installed a new programmable thermostat when the furnace was installed. It was difficult for me to program so when they came out for a routine inspection I asked that it be replaced. The serviceman was very patient in showing me how to program the new thermostat and gave me a discount for being a repeat (plan) customer.

Matt did a quick check of the basement unit and then went outside. He said it likely was a failed capacitor and that's what it was when he tested it. He had a compatible part in his vehicle. Once he had installed the replacement the system ran perfectly. We were so glad we were able to be serviced the same day that I called in the problem. Hello summer.

Technician Bob Going was on time, very proficient and professional. Over the years I've used several different companies for AC clean and checks. Bob did the most thorough cleaning of the outside unit ever. He shared his recommendation on how expensive of a furnace filter is really needed and gave me other tips on HVAC operations. I will definitely use SmartHouse again and request Bob. I plan to enroll in one of their maintenance agreements for easier, continuous care of my HVAC system.

Called Smarthouse on a Friday afternoon not expecting to see anyone that day. I was able to set up an appointment that was convenient. Scott came on time and was thorough in his diagnosis explaining the issue with our A/C and the action needed.

I can't edit my previous review - but wanted to give them a slightly better review. It took a month to receive my audit and there really wasn't any communication during that time. They did what they could to make it right and we may consider hiring them for some other work.

Please feel free to contact me if there is anything we can do to be of service. Stephanie Seemiller, Operations Manager [phone number removed]"

The technician Joe was very pleasant and polite, he kept me informed on everything he was doing . He was very thorough, I learned a lot from him that day.

The outcome was horrible. I kept waiting for the areas that had been done to start showing some signs of warmth but that never happened, if anything they kept getting colder and colder which was worse than they were before the work was done. With the below freezing temperatures we have been having it is really unbearable to enter those areas. After complaining about the job done it took Tim awhile to get out to check on the matter . I am too disappointed and mistrusting of the new proposal he has presented to me. All I want is a refund for a job that was poorly done.
Response from SmartHouse Heating & Cooling
"[Member Name Removed], We are sorry to hear that you were unhappy with the results of the insulation work done at your home. We are confident that the insulation added to the foyer and closet above has added thermal R-value to the spaces. However, without a heat source to those locations, the insulation itself will not add heat or warmth to the space. The barrier to the outside, or the shell of the home, works as a continuous layer of protection from the outdoor elements. While we were able to address these 2 specific areas, the follow up recommendations made by Tim were made to suggest the next steps to complete the sealing and insulation to remainder of the shell of the home. This would prevent air infiltration from the outside, and allow the conditioned air to remain in the home where you need it. We are happy to review the energy audit findings and full recommendations with you to help get closer to your goals. Thank you, Stephanie Seemiller, SmartHouse Heating and Cooling"

The analysis went very well. Tim Renz was very professional, thorough, informative and polite. While at my home he gave me suggestions, never pressuring me in any way. The next day he emailed me a complete analysis and cost information should I decide to use his company.
