Job Checkin

Performing a diagnostic service on a 1996 furnace that was not coming on or heating the home in Clayton, CA. The furnace mysteriously began working as soon as I entered the attic and began heating the home. The client joked that it was the “Brittany Effect” and that I scared the furnace into working. The client became our newest maintenance member so we can continue making sure the system is working safely and efficiently! Thank you for choosing Certified Heating & Air Conditioning!
