From beginning to end Yvonne Gonzales was incredible. Very professional and explained every step she was doing to I could understand. Signed up for Certified Performance Agreement, a great deal and keeps you up to date with furnace and air conditioner maintenance - Yvonne is also good sales person! I recommend them with 5 out 5 stars.......as well as 5 stars for Yvonne.

I had my heater serviced on Oct 17, 2017. I started using it in November. This heater has never worked this well since I have owned it. It has gone from noise to silence during start up! I'm so happy with the service Certified provided.
