Walnut Creek is a city in Contra Costa County in the East Bay Region. It serves as a hub for neighboring cities because of its location at the junction of the highways from Sacramento and San Jose, and San Francisco/Oakland and its accessibility to BART. Walnut Creek’s warm summer Mediterranean climate is typical of California’s interior valleys. In summer, high pressure leads to near unbroken sunshine and virtually no precipitation, so having a reliable company for AC repair is important. Days can be cool in the winter, and furnace maintenance is important as well.

Performed tune up on 12 year old Bryant high efficiency furnace. Unit is in very good shape as she has it looked at every year. Found some loose dryer sheets in the blower motor, removed and cleaned the wheel of all debris. Adjusted gas pressure in low stage for better heating efficiency

Performed maintenance on 11 year old Trane furnace. Unit has ductwork that has been crushed flat. Gave quote for repairs. Cleaned out entire system, clients have long haired pets. Replaced a blower capacitor and all else is good.

Performed AC maintenance on 2 year old Goodman. Unit is in good shape, has had a failed dual capacitor in the past. Refrigerant levels are great and unit is working well. Client is on our maintenance program to ensure unit efficiency and reliability.
Chris R.
Installed new circuit board to prevent failure due to major burn marks on original. New board came with brand new hot surface igniter and one year warranty. Also installed hardstart kit on air conditioner to lower amperage draw on compressor, this will prolong life expectancy, lower utility cost and relieve stress on system

Ac maintenance
Lucas G.
Performed tune up on 5 year old package unit in rooftop. Unit is not cooling the house very well. Found that the unit was low on refrigerant causing it to work harder and not remove as much heat from the home. Topped off refrigerant. Coil was also very dirty as the filter was poorly installed with the unit. Cleaned unit and added a new filter and sealed it in place properly. Added a hard start kit and reduced starting amps by 46. Joined maintenance program to properly maintain unit.
Chris R.
Replaced attic fan in gable vent to help remove heat out of attic, which lowers heat load on home so that air conditioner does not have to run as much
Tyler B.
No cool in Walnut Creek. Client said it turns on but doesn’t cool. Opened the coil and saw this.
Chris R.
Performed tune up on air conditioner, replaced filter and cleaned outdoor unit. Checked capacitor, contactor, electrical connections, refrigerant levels and amperage draw on compressor, condenser fan motor and blower. Fixed incorrect wiring in furnace and thermostat, added two pounds refrigerant per tune up special.
Chris R.
Performed two system air conditioner tune up. Both systems run upon arrival, checked capacitors, contactors, electrical connections, refrigerant levels and amperage draw on compressors, condenser fan motors and blowers. Both systems are over 30 years old. Systems are worn out but still functioning, due to condition, age and efficiency I do not recommend any repairs be made and only recommend replacement.
