With the fall season upon us, many homeowners are turning on their furnaces for the first time in a while. This can often bring a feeling of anxiety as you wonder whether or not your system will work correctly. Luckily, there are a few things you can check to make sure your unit is functioning properly.
If your system isn’t producing heat or if some rooms are colder than others, it’s likely due to uneven heating. This could be caused by a clogged filter, a broken thermostat, or a damaged heating element. To fix this, you can try turning the thermostat up or down, cleaning the filter, or using caulk to seal any drafty areas in your home.
Another common problem with furnaces is that they shut off unexpectedly. If this happens, you’ll want to make sure the thermostat is set to “Heat” and that it’s not on “Cool.” You’ll also need to make sure your gas supply is on. If it’s off, your ignitor may not be able to ignite the gas, and this will cause your system to turn off. Check your breaker to see if it’s tripped, and if it is, reset it. You may need to do this a few times before you can get your system back up and running.
A faulty flame sensor may be the culprit for an intermittent shutdown. The flame sensor is constantly exposed to hot temperatures, which can cause it to wear out over time. This can cause it to create a coating that creates an insulative barrier that reduces the signal it sends to the circuit board, making the system think there is no flame. To fix this, you’ll need to take the sensor out and clean it with an emery cloth.
Having your furnace Furnace Repair serviced regularly by an HVAC professional can help you avoid these types of problems and extend its lifespan. Keeping an eye on your utility bills can also help you determine when it’s time for an upgrade to a newer, more efficient furnace. While a new system will cost more than repairing an old one, many experts use the rule of thumb that if a repair costs 50% or more than the price of a replacement, it makes sense to replace the unit.
