What Would Cause A Furnace Not To Switch On?
- Thermostat Problems
As you know, the thermostat is an important component of your furnace. If your thermostat does not work efficiently, your furnace cannot warm your home comfortably. You must ensure there are no problems with your thermostat.
For this, you should ensure your thermostat’s batteries are not low and that it is installed in the right place. Moreover, your thermostat should be compatible with your furnace. If you want to avoid problems with your thermostat, ask your technician to install a smart thermostat.
- Gas Line Issues
If you own a gas furnace, you should ensure there is no restriction in the gas flow from the gas line to the furnace. You can check this by using any other appliance that uses gas. If the other appliance does not work properly, it means there are issues with the gas line.
If you smell a gas leakage, you should vacate your home immediately for safety reasons. Ask your technician to install gas detectors in your home for such situations.
- The Age Factor
All HVAC appliances have a fixed lifespan for which they can work efficiently. Any appliance that has crossed this range needs numerous repair jobs to work suitably, and the same goes for furnaces.
If your furnace is more than 15 years old, it is too old to function and needs a replacement. Investing your money into a new and energy-efficient furnace is better.
- Duct Issues
The ducts in your home are responsible for circulating hot air evenly in your home. With your ducts, your home will reach a comfortable temperature. Since ducts are so important, they cannot avoid wear and tear damage, and you need to check them frequently.
Ensure no leakages or holes in the ducts that may allow the hot air to escape through them. Also, ensure there are no restrictions in the ducts that may create hot and cold pockets throughout the house.
- Dirty Air Filters
Air filters of your furnace are extremely important for the efficient functioning of your furnace. If your air filters remain dirty for a long time, you will face problems like poor indoor air quality, allergies, and poor heating efficiency. You must frequently check your air filters for cloggings and replace them whenever necessary.
