In the Fairfield area performing an AC maintenance! This 12 year old AC unit is working like a champ! During the inspection, I noticed the condenser is amping very high at the start, which is never good! This puts a lot of stress on all your major components and causes premature failure! After making recommendations to my customer, we came to the solution that hard start kit would be the best thing for his unit at this age! We installed the hard start kit, and it brought his amperage down alot!

Checking out of Fairfield ca. Today I changed a gas valve on a carrier furnace from 2006. There are other things going downhill with this one. The blower motor is leaking oil. Both motors in attic are over amping and the furnace is almost reaching its maximum outlet temperature meaning it’s getting too hot. I’m happy we were able to get heat today ! Thank you for choosing team CERTIFIED!
