Finally, don't underestimate the thermostat as a potential reason why your furnace is not working. Everything on the heating unit itself may function perfectly, but your home still will not heat right if the console you use to set the temperature doesn't communicate your input. A faulty thermostat can either be due to the wall unit itself, or the wiring that connects it to your furnace. Average thermostat repair costs are between $108 and $282, including labor. Replacement costs, of course, depend on the thermostat you choose. Visit our thermostat repair cost guide to learn more about this type of issue.

Our new HVAC unit started to leak badly, so we set up an appointment for an on-site diagnosis. The two-man crew arrived in the agreed-upon window and was very experienced. They gave off the impression that they had seen just about everything before. They quickly found the source of the problem, fixed it, and explained in full what they were doing and why. They also offered up some helpful tips of what to look for and how to self-diagnose issues.


Walter was stupendous! He installed a new high-efficiency central air and furnace in my house. His master craftsmanship (artistry) and customer service are in a class of their own. From removing the old unit to all of the finishing touches, testing and review of operating the system, every detail was done in excess of what I could have imagine and I'm a Building Inspector. It was a very pleasant experience for me with only good surprises.

2Be sure the furnace’s circuit breaker is on or that its fuse has not blown. Check both the main electrical panel and any secondary subpanels that supply power to the unit. If the circuit has blown or tripped, reset the circuit breaker by flipping it all the way off and then on again. Or replace the fuse. If the circuit blows again, there is probably a short in the electrical system providing power to the furnace. For this, you may need to call an electrical contractor.
High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
