Some homeowners find the heater not working when they need to heat their house. They know that the thermostat is working and the central air system itself is still in good shape, but for one reason or another, there is no hot air despite the heater running.
As odd as it may sound, this is not an unusual problem. In fact, there are several reasons why you might be experiencing this in your own home.
(Side note: We normally refer to the heater as the furnace, but in this article we will use heater and furnace interchangeably.)
Furnaces built after the 1990s come with a safety switch or safety shut out. These are safety measures put in place to prevent heating and air conditioning if there is a technical issue that can cause a hazard. In these cases, no matter what you do to the thermostat, the furnace will never kick in until the problem is found and fixed.
Such problems can include:
Whatever the issue may be, when the entire system refuses to start, homeowners need the assistance of their preferred HVAC contractor for further diagnostics on a heater not working.
The central air system requires several different power resources. It uses gas, electricity and even water. Consequently, it is easy to lose track of what is on and what is off. Sometimes, homeowners call AC technicians about a problematic furnace only to discover that the power breaker was off.
In similar fashion, it is common to find that the furnace has trouble finding gas to use. This can be because the gas valve is stuck or the control board is unable to communicate. In these situations, the furnace is ready for heating, but because it is unable to build a flame, it cannot proceed with the process.
If all other gas appliances in your home still work, you may need to call an electrician to help troubleshoot.
Homeowners may encounter the peculiar problem of having heating stop after working briefly. This occurs when the furnace detects a problem mid-cycle. More often than not, it is simply matter of furnace maintenance.
Homeowners regularly underestimate how important and effective furnace maintenance can be. Just one appointment clears out residue, buildup and debris that can hamper energy efficiency and heating quality.
