Why Your Furnace Isn't Working As Expected
When the cold weather sets in, you want to make sure you have a functioning heater. Most people usually seek heating services for maintenance and repair to ensure the unit functions optimally throughout the season. Unfortunately, mishaps can happen unexpectedly, causing the system to break down when you need it the most.
Issues like malfunctioning pilot lights and short cycling are common, but when you face them, you shouldn't panic. Maybe you can diagnose and fix it, or you might need an HVAC technician's help. Below are some common reasons why furnaces stop working and things to do to remedy the situation.
The Filter May Be Dirty or Clogged
One of the primary reasons your heater may not be warming your home as expected is clogged or dirty filters. Clogs cause the heat exchanger to overheat and eventually shut off. Dust and dirt also promote soot accumulation on the heat exchanger, causing the heating system to run less efficiently. This increases the utility bill because the unit will overwork in an attempt to meet your needs.
Cleaning the filters can help solve this problem. However, if this is done and still no heat comes out, you may need to replace the filter or get a technician to examine the blower. Filters should be changed regularly, particularly if you have kids or pets.
You Have Thermostat Issues
If the thermostat is faulty, it will be impossible to turn on the heat. Usually, this occurs if the device isn't set correctly or when its components are broken. The thermostat's function is regulating the quantity of heat that's generated by the furnace and determining when the heat should be generated.
Most of these devices can work for years and are reliable, but eventually, they can develop issues. You'll need to get a technician to repair or replace them when this happens. Consider choosing a programmable thermostat if you need a replacement so you can pick various temperatures for the day and night.
The Blower Capacitor Isn't Functional
The blower capacitor is the component that starts the furnace once you set your thermostat. Each heating system's capacitor has a varying tolerance level, so if the level reduces past a certain level, it will become difficult for the blower to attain the proper RPM. In other cases, the capacitor might be dying or dead and cannot start the blower. The best solution to this problem is a replacement.
