Good customer service

Heater went down during a snow storm. Carl came out next day and diagnosed the issue and was able to fix it same day. I felt the price was very fair also. Would call again.


Response from CW Mossor Heating and Cooling:

Thank you for your kind words, Travis. We appreciate your business and are glad we were able to get your heat pump fixed quickly and efficiently.

Competent and dependable

Carl was able to get to our house on short notice on a weeknight when we sprang a radiator leak just before Thanksgiving with a houseful if guests on the way! Looked like a disaster looming but he got the problem stopped quickly and gave us an accurate estimate of the time it would take to get the radiator replaced. He always showed up on the date and time he promised. He was very clear in his communications via text messaging. All in all he did a first- class job! Will definitely call on him again in the future for our furnace & radiator care.
