Carl was here within about 20 minutes of the initial call This was 100° day and my air-conditioning was completely out Carl had everything back up and running very quickly You’re not going to find better service or technician than Carl Mosher and sons

Excellent service
Thank you.
Carl was very helpful and understanding. He was able to fix our AC problem the same day.
Very professional and thorough
HVAC replacement install. Carl was prompt, courteous and constantly kept me in the know of what was going on. Some issues arose with the install but Carl worked through them with patience. The install took longer than planned, but Carl worked diligently. I will use him in the future for servicing this unit as well as my other unit. Carl is meticulous and detailed in his work. He does not cut corners and does the job required. Pricing is very fair. His quote included a few other things other installers did not even consider and his price was even a little lower than other installers for similar equipment.
Thank you. I am very happy that you are pleased with the work and hope to continue providing excellent service in the future as well.
It’s been 3 years since I started using Carl’s service, and I’ve never been disappointed. Honest, hard working, and a true professional. You receive an arrival time, and it’s not a 4 hour window. If he says 10am, you can trust he will be there. Thank you

Mr. Mossor always informed me of what he was doing each day he came to my house to replace my upstairs furnace and AC unit. Was on time everyday and took great care while working in my home. I could not have contracted with a better person.
