Step by step information
Louis - Pittsburg, CA 94565
every step that was taken and everything thing that was done was explained. Not in a way to make me feel stupid or technical info that didn't make sense. The service was great and Diego was amazing. A call before they came over, a text with a picture of the servicer. This was a great experience.

Brittany B.
Performing diagnostic service on a 1999 Carrier furnace in Pittsburg, CA in the Oak Hills neighborhood. System has a failed blower motor that is not pushing air through the system which has caused it to overheat and shut down. Went over replacement options with these awesome clients and look forward to bringing heat back into the home to make them more comfortable! Thank you for choosing Certified Heating & Air Conditioning.

In highlands ranch of Pittsburg this afternoon. Performing a furnace maintenance and a/c safety check for the Passmore residence. Their system was only 5 months old but they’re being proactive about their investment and have scheduled maintenance every season!

In willow cove of Pittsburg this afternoon performing a furnace maintenance for the Marx residence. Even if your system is only 2 years old, be proactive like the Marx residence. After their maintenance today they will be helping the longevity of there system!
