Earlier today we finished up a 3 day install of 96% high efficiency furnace and duct work replacement in Berkeley. After we finished that job we headed out to Oakland to install to install a 80% furnace. With certified solar heating and air conditioning, no matter the work load we are capable of getting the job done and providing our client homes with ac/ heat!! 💪🏾

Diagnosing 2009 Williams double sided wall furnace in Oakland, CA. The system had tripped the high limit due to dust accumulation, dusted it all out, reset the switch and the system came on and began heating the home! Client is now a Certified Performance Member so we can clean out the heater each year before the season begins to avoid premature failure. Thank you for choosing Certified Heating & Air Conditioning!
