Vallejo is a waterfront city in Solano County, located in the North Bay subregion of the Bay Area. It is geographically close to East Bay and sometimes associated with that area. Vallejo has a mild, coastal Mediterranean climate and can be an average of 10 °F (6 °C) cooler than nearby inland cities. Vallejo is influenced by its position on the northeastern shore of San Pablo Bay, but is less sheltered from heatwaves than areas directly on or nearer the Pacific Ocean/Golden Gate such as San Francisco and Oakland.

Tom - Vallejo, CA 94591
Let me say professional, polite, clean, no rush, exceptionally competent, scheduling to meet your needs and ready to answer any questions as well as taking the time to explain things if your so inclined to want to learn more about your HVAC system. Those are some of the thoughts that come to mind when thinking about my experience with Certified Heating and Air Conditioning. It started in the office with Kim's very pleasant and service oriented personality in setting up and scheduling my job and ended in the field with Brittany and Jill, who's experience and work ethic resulted in a job well done. I would definitely recommend this company to all. Keep up the good work and God bless America.

Ac maintenance

Furnace tune tuneup
Lucas G.
Performed AC Maintenance on 26 year old HEIL ac. Unit doesn’t come on all the time. All components are working but is pulling a lot of energy. Had to add a hard start kit to bring down starting amps in order to get the compressor to turn on reliably. Unit is now working again
Lucas G.
Performed air conditioner maintenance on 18 year old Carrier. Unit is having a few issues but are attributed to the age and wear on the unit. System is still cooling the house but not as efficiently.
Chris R.
Performed diagnostic on air conditioner found blower not coming on due to failed circuit board. Bypassed to test system and found blower at max allowed power consumption by manufacturer and blower capacitor well below spec at 1.7 and rated for 5. Heat exchanger has thermal stress. Compressor at max allowed power consumption by manufacturer and system has small leak in suction line service valve. 31 year old furnace and 27 year old air conditioner

Ac maintenance
Brittany B.
Returned to perform repairs on 2003 Goodman condenser, system runs but was not properly cooling the home. Checked evaporator coil and filter for airflow restrictions, none at this time. Balanced R-22 refrigerant and added a compressor saver kit to ensure the system will function and cool the home during the blazing hot California summer.
Brittany B.
Performing diagnostic service on 1986 Day & Night furnace that was not running on arrival. System has been overheating and short-cycling due to dirty and leaking blower motor and extensive wear inside heat exchanger.
