My HVAC system had not seen a tune up or service in over 5 years and is starting to get on the old side of operation, so called around to a few different companies. Coretemp had a rapid response and set me up for an appointment next day which was impressive.
Service tech came within the specified arrival time and was very friendly. Got to work and explained things as he went along. Checked all aspects of the furnace and than moved on to the AC unit. I had mentioned my AC unit was not cooling as well as it had in the past. Upon inspection he noted my unit was a little low on refrigerant which could explain why my cooling was not as expected.
Offered a few different solution being very honest with expected outcomes. Topped up the refrigerant for a nominal fee at my request. At the end he gave me a detailed work order of things he checked and recorded values for future reference.
Overall great service from very friendly staff member and would not hesitate to call them again if I have issues or looking to upgrade my HVAC system.
