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:

Excellent Service

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.

I appreciate Carl's promptness, attention to detail, and explanations of service recommendations. I've never felt pressured from an "upsell" that I've encountered from some other HVAC companies.

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.

Knowledgeable service at a fair price

Carl was quick to respond to our request, he offered a fair comparable price to other companies and he was able to point out some installation issues for a new unit that other service techs had not noticed prior to beginning installation.
