Excellent experience!




We called certified for a heating problem. Brittany came to service our unit and not only was she very nice and professional, she was honest. She didn't try to sell us something we didn't need and she fixed our ignitor free of charge. I will definitely be using this company again! Great service!

Highly Recommend !!




Tyler performed a check and tune-up of my furnace and air conditioner, and cleaned the dryer vent. He was very nice, efficient and professional, and the price was very reasonable. I highly recommend Certified HVAC.

Very satisfied with the service




Brittany was friendly & personable, respectful of my house, informative & thorough (explained the issues with my out dated system), provided options to repair or replace with some estimates for repairs and very nice & patient with my little dog who barked at her often just because she can.
