Kierce Heat Pumps and Mechanical is a Richmond heat pump and mini-split installer with 5 stars from 54 Google ratings. A recent customer had five mini-split units installed throughout their home in one day, and says Ryan connected the system to their WiFi and explained how it runs. A recent customer says Ryan quoted Mitsubishi Hyper Heat pumps for less than other contractors and told them about a NH rebate on replacing electric resistance heating that saved them $8400. A recent customer had a 5 head mini-split system installed at their house in Nashua and says the exterior lines are neat and minimal. Ryan and his assistants replaced a 28 year old oil furnace with a new system for a recent customer, who says a bad O ring was quickly corrected. The work goes past installs. A recent customer says Ryan cleaned two mini-splits after a bug infestation and found dead insects in the condensation pan. A recent customer says Ryan replaced their hot water heater and fit a larger size into a very constrained space in a seasonal cabin. In a 2025 review, a customer said Ryan installed a whole home heat pump system within the same day and walked them through the Mass Save process. The company lists free estimates. A recent customer says Ryan stayed longer on the last day to wait for the propane company and helped figure out where to place the new propane tanks.

“We just had a new Mitsubishi heat pump installed. Installation was done on date promised. Very clean, no mess to clean up. In depth discussion on how the units work and app put on phone to be able to make changes to heat, or air remotely. Excellent job!”
I certainly would recommend Ryan as your HVAC dealer. He cleaned my 2 minisplits following a 3 month no see um bug infestation . He did a thorough deep cleaning and did find dead insects in the condensation pan and He did a thorough job which I have never received before !
Ryan and his assistants replaced our 28 year old oil based furnace with a new system. Right from the start of an elongated quote process that involved exploring different systems, Ryan patiently accommodated my questions and concerns about the pluses and minuses of all options. Once the decision was made, he followed through with his typically highly organized and Conscientious approach to the installation. There was one glitch with a bad O ring that he quickly responded to and corrected. As I have stated in past reviews of Ryan’s work, he is always as responsive as he can be in getting back to you if there are issues that need to be discussed or acted upon. I highly recommend him and his crew and continue to be confident in his expertise and willingness to provide sound advice on a wide variety of HVAC topics.
I highly recommend Kierce Heat Pumps and Mechanical! Super reasonably priced with good quality equipment, plus they were super helpful and knowledgeable throughout the whole process, which for us who didn't know a ton about what we were looking to get done was wonderful! We are very happy with our new efficient heating/cooling system, thank you so much Ryan!!
Ryan and his crew did a great job. He always kept us updated on when the job would start and what it would entail. There were no surprises and the final job was even better than expected. I highly recommend Kierce Heat Pumps and Mechanical.
Ryan was great to work with and his pricing was very competitive! We were looking at having a new whole house heat pump system and a new hot water heater installed. He was prompt in meeting with us and walking through the entire the process. He was able to help us figure out financing for the project and gave us a few options to work with. Ryan and his crew were all professional while in our home and worked with us as one of our dogs has anxiety around people and they made sure that she was as comfortable as she could be while they were here. They were on time each day and the job was finished when Ryan said it would be. Ryan stayed longer on the last day to wait for the propane company to come and was helpful in figuring out where to place the new propane tanks. I would highly recommend Kierce Heat Pumps and Mechanical for your HVAC needs!
