Gerding Heating and Air Conditioning 81 Colonial Circle, Harrison, ME 04040

"Fantastic experience with Gerding Heating and Air Conditioning! Dave is very responsive, is professional and can be counted on. He expertly installed two minipumps and when there was a problem a year later, he took care of it quickly. I highly recommend."

"I highly recommend David and his team. I have no affiliation with them and did my own research of 10+ companies across South Maine and the Valley - they were my top choice and they did not disappoint. They worked professionally, quickly, were responsive to all of my questions, and clearly explained each step of the process along the way. The finished products look (and work) great: new efficient furnace and duct system for main house, and heat pump for small secondary structure. I will absolutely hire Gerding Heat & AC when needed in the future, they are fantastic."

"David did a fantastic job and was a pleasure to work with every step of the way from quoting to installing to start up. He and his team were amazing at communicating arrivals and every other aspect of this project. They were even great at putting up with my curious dog and child whenever on-site. I look forward to working with them long into the future while updating this Ol’ House! just look how clean of an install it is, such an upgrade! Couldn’t be happier!"

"David is excellent to work with. I called him about putting in heat pumps in my house and he came out 2 days later to look at the job. He went through all of the details of what I needed and made recommendations on all of the locations and equipment. I had a quote for the project and hard installation dates within a couple of days. He came on the dates he said he would and installed the system. David and his team do quality work. I would recommend him first to anybody looking for HVAC work in the Maine Lakes Region"

"David responded very quickly and even tried to troubleshoot the ductless split at my house on the phone. He eventually had to come to fix my Fujitsu unit. He explained what the problem was and clearly answered all the questions I had. I recommend Gerding Heating and Air Conditioning."
