Quick, Honest Diagnostic of an Old Furnace




Heard about Certified Heating & AC on the radio, decided to give them a call - we just moved into an older house with furnaces that hadn't been inspected in many years. Brittany was super-efficient and gave us the facts & options to move forward. Just what we needed. Thanks!

Diagnostic on a broken Day and Night natural draft furnace from 1990. Discovered failed control board, and due to age, efficiency, and cost of repair and future repairs client elected to replace the furnace with a more efficient and far more reliable system. Client became a maintenance member to ensure the new system runs safely and efficiently. Thank you for choosing Certified!
