Gas furnaces keep homes warm and comfortable and heat water for use during winter.
- This HVAC equipment protects the home walls from molds and moisture by keeping the indoor temperature at the required level.
However, it breaks down occasionally. When it does, it puts your home’s indoor environment at risk. You have to restore it by fixing all the faults in the HVAC unit. To do this, you need to start by turning off the thermostat and your furnace switch. After that, check your gas furnace’s air filter for dirt, debris, and clogs. Furnace air filters accumulate dirt and debris over time and block. Clogging impairs airflow in your system and deteriorates indoor air quality. An excessively clogged air filter is also a potential cause of fire hazards and premature breakdowns. To test the air filter for clogs, hold it against a source of light. If the light does not pass through your air filter, you should replace it. Second, check your thermostat’s settings and batteries. Ensure it is set at heat and the batteries have power. Clean the thermostat and confirm it is receiving accurate readings. If this does not fix the problem, inspect the furnace’s switch and electrical panel. Ensure they are all turned on. Look for a discolored or melted fuse and replace it with a similar fuse to restore power to your fuse box. Finally, check all your registers and vents to make sure they are open and clear. Blocked vents and registers can result in excessive air pressure leading to duct leaks. It may also cause premature HVAC breakdowns and repairs. When you secure everything properly, fit your front panel and press it all the way into its original position.
