Great Service




Certified Heating & Air Conditioning provides excellent service and their technicians were all very knowledgeable, polite and communicated well when trying to fix our many issues. Working with Brittany, Ray, Joey, Kim and company was a great experience and I would highly recommend their services to anyone looking for new duct work and wanting to make your AC unit more efficient.

Because of Brittany's excellent presentations, and explanations, I feel Certified Air will do a very job on our AC unit. We are scheduled to talk to one of your technicians on Monday afternoon.

Fantastic Service!!!




OMG Certified Heating and Air's service is fantastic, beyond my expectations! I left a panicked message on a Sunday about my AC being out during a recent heat wave. It was 107 at my house. I also have pets that I was very worried about. On Monday morning before 8am Kim called and said Tyler could swing by before his 9am appt. Tyler arrived and was very polite and professional. He immediately diagnosed the fan motor was out. The part was not standard so it had to be ordered, but he had the part overnighted for next day delivery! That was awesome! On Tuesday Kim called to let me know Brittany was on her way to install the fan motor. She was also very polite and professional and had the SC running in a few minutes! I'm thrilled with the people and service at Certified. I will definitely call them again! Kat

Performing diagnostic service on 2003 Carrier furnace - system not functioning on arrival. Diagnosed failed blower capacitor, dug through system to find out what caused the capacitor to fail and discovered that the system has high static pressure due to undersized ductwork. High pressure has caused several issues that could have been avoided with regular maintenance services (i.e. blower motor leaking oil, heat exchanger thermal stress, worn igniter, etc.) Made recommendations for long term fix.

Performing furnace maintenance service on 2005 Lennox furnace. Cleared out clogged drain system for high efficiency furnace and removed a lot of water and debris. Inspected and tested all electrical components and cleared dust from inside system. Very fortunate that the drain issue was caught before water was able to drain into furnace resulting in damage and potential repairs.

Performing diagnostic service on 2007 Trane furnace, system was overheating and shutting down, only the fan was running when I arrived. Discovered that insulation inside coil was hanging down and blocking the airflow, trapping the heat inside the furnace and causing it to shut down. Made repairs and recommendations, system is now up and running!
