Service, price great. Sorry I didn't do it sooner.




Review of Certified Heating and Air Conditioning

Only so much can be done with a 50 year old system but I can tell ac performance is improved. Learned a lot about how to keep system performance optimized in its twilight years.

Great job!




Review of Certified Heating and Air Conditioning

Yevonne was very personable and able to answer the questions I had. If she was not sure, she was able to check with someone who did have the answer. Would definitely recommend and would use again in the future.

Providing an estimate to replace a furnace and add a condenser and coil to a lovely home in Sunnyvale, CA. The clients would like to relocate the furnace from a closet in their hallway to the attic and add air conditioning to the home. Went over different options with the client to ensure there was a good understanding of how the systems work and which features could be beneficial to the homeowners. We look forward to working with you and thank you for choosing Certified Heating & Air!

Performed maintenance on 11 year old American Standard air conditioner. System is in good shape, we’ve been monitoring refrigerant levels for a year and it had dropped below required level, recharged unit and it is working much better now. Client is happy with her service and wants to continue her yearly maintenance program.

Performing precision tune up service on 1998 Trane system (AC and Furnace). Good thing we came out because the blower cabinet insulation came off the wall and was completely blocking the blower motor on one side, which is now fixed. System was starving for air and causing pressure to build up inside the furnace. System running much better, cleared out dirty drain line and added hard start kit to protect compressor motor. Clients are now Certified members to continue getting the best service!
