Performing diagnostic service on a 1990 Day & Night furnace in Novato, CA. The system has a bad circuit board and due to the age and condition of the furnace the client decided to replace it with a 2 stage variable speed furnace that will make the house far more comfortable. Offered financing options to ensure client has 0% interest over 5 years for the new system. Thank you for choosing Certified Heating & Air Conditioning!
