Great service!!

Jackie did a great job of explaining everything that she had done to keep our furnace working well. She was very meticulous in her work and her explanations. Jackie also took the time and effort to answer all my many questions. I really appreciated her work.

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!! 💪🏾

Let’s take a look at this 2020 Goodman furnace! There was some water flooding around unit in basement. We will not leave you hanging! These are things we can assist with if it will affect our machine! Let us know and we will be glad to help! Thankfully no water reached inside! Here in Oakland ca!

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!
