Chris and Juan are the best installers hands down!




Review of Certified Heating and Air Conditioning

Extremely professional, high quality craftmanship on a comprehensive AC install. Their custom work to make it work for my home's set up is impeccable and were extremely communicative and informing throughout the process, and were an absolute pleasure to work with.

Awesome service by Mateo




Review of Certified Heating and Air Conditioning

Mateo was fantastic. He came for my spring service and found that the capacitor in the AC unit was out of spec and the squirrel cage of the blower needed cleaning. He had the capacitor on the truck, which was awesome and was able to clean the blower making it like new again after years of build up. Glad to have my system in top shape for the hot season !

In the Hayward Highlands neighborhood of Hayward, California. Client had a company install a condenser but did not install a new evaporator coil. The old coil has R-22 refrigerant and is not compatible with the new condenser. We looked at solutions to fix the current issues and look forward to getting everything working properly.

I just preformed an AC maintenance in Fairway Park for my client, Chris, who is on the maintenance plan. I was happy to clean the furnace fan to ensure it runs efficiently and provide better air quality for home! 😀

In the Hayward area performing a furnace diagnostic! This 2 year old was said to be running a little funny. After inspecting all areas of this furnace, nothing was detected which is always good news! We recommend getting maintenance done once a year for your furnace to ensure it remains running properly!

In the Hayward area performing a furnace diagnostic! This 4 year old system was not starting properly due to a Flame sensor not being cleaned! This is why it is very important for maintenances to be done once a year!
