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 !

I am in Hayward, California to look at adding a ductless mini split system to a warehouse. The building is used for metal fabrication and the client would like a system that is capable of cooling the work area.

I came out to the Cherryland neighborhood of Hayward, California to look at a central gas furnace. The homeowner was told that she needed a new furnace, but after inspecting the current unit, I found that this is not the case. Her current modulating unit does not have the proper thermostat installed, restraining it from operating at its full potential

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.
