I used Cottam for the installation of a heat pump plus two mini-splits as auxiliary HVAC for my home as part of a larger renovation project. My general contractor referred me to Cottam, and I was very pleased with the service. Blake Cottam came to evaluate the house and to discuss the options with me: knowledgeable, personable, and reasonable with my naive questions about the systems we were considering. He and his office team provided prompt and close attention to scheduling. The installation itself was smooth. The technician who came to instruct me on the use of the new system was a bit unpolished and had some difficulties with the computerized apps (and he was much younger than I, certainly a digital native!), but his difficulties were a minor glitch, and were resolved on a follow up visit.

Subsequently, I realized there was a problem with the placement of one of the mini-splits, for which I take responsibility. Blake and his team willingly scheduled the corrective installation (for which I paid additional fees). I had more interaction with this team, the very professional and accommodating George and Tom. They were patient and competent, making sure I understood what they were doing and that I approved.

I definitely recommend Cottam for smooth, professional and attentive service.

We just had an great experience. Our AC unit stopped working and Cottam was all over it. They had us up and running with cool air in just a few hours! Thank you George and Lawrence for all your hard work!

I just had a great experience with Cottam Heating & AC installing a new HVAC system.Hector and Anthony worked really hard on a difficult job and had a great attitude the whole time. Blake went above and beyond. I also want to add that Roberr did a fantastic job in fixing an old noisy AC. He took extra effort to make sure that the new unit ran smooth and quiet. This is a very professional company, and I highly recommend them

They were highly professional working on a very old AC unit which required some nuanced skill from older days. Diligently and quickly acquired parts to repair AC quickly in just a day. Very respectful, skilled on specialized challenge, and reasonably priced. High recommend.

We had Cottam install a replacement water heater. Terrance and Isaiah installed the new system exactly as promised. They were neat, clean and kept us informed of what was being done. The job was completed on time and everything worked perfectly!

Umberto Isiah and Rob removed a boiler and hot water heater and put in a newer tankless combination system. They were great knowledgeable and friendly. Austin came prior to find out what system would be best for my house and gave me options to choose from. Set up a yearly maintenance plan with Cottam. Overall great experience.

George and Hector were great technicians that helped install a Mitsubishi hyper heat ductless HVAC system. They took time and addressed any concerns I had and overall I am more than satisfied with the installation.

Without exception, all of the COTTAM staff who handled this installation were experienced, knowledgeable, service-oriented,
& a pleasure to work with. George, Joey, Robert & PJ consistently and effectively represented your Company in all that they did. Your administrative staff is terrific. The stable execution of this complex project is a credit to the entire Cottam Family. We have known Gary & Vicki for many years & our home in Rye is all the better for our continued partnership. Kudos, one and all. Best, Julie & Jim

Cottam Heating & Air conditioning, just installed a new furnace for my home. Best experience we’ve had with HVAC folks.
Humberto led the job, he was super knowledgeable, explained everything without talking down to me, and kept things moving. Derek jumped in day one and was quick, clean, no mess left behind. George took over the second day same deal, polite, efficient, and they wrapped up right on time.
Thanks Humberto, Derek, and George, your work made winter feel way less scary. Highly recommend Cottam Heating & Air Conditioning.
