Troubleshooting Tips For A Broken Furnace

All homeowners know the importance of an efficient furnace during winter. The worst scenario for a furnace owner is when their furnace unexpectedly stops working. Believe it or not, several furnace owners face this problem at least once during winter. The best approach to avoid this situation is by contacting our technician at South County Air Services, who provides heating replacement services in Mission Viejo, for the annual inspection of the system.

If Your Furnace Unexpectedly Stops Working, Here is What You Can Do to Turn it Back on:

  • Clean The Air Filters

Without your air filters, your furnace cannot perform several functions. Air filters help purify indoor air and keep dust away from the internal parts.

If the air filters remain dirty for a long time, dust will enter the system and cause damage to the parts. Damaged parts cannot work efficiently, and your furnace can temporarily stop working. The best approach to fix this issue is by replacing your air filters at least once a week.

  • Check The Thermostat

Your thermostat checks the temperature your home needs and instructs the furnace to work accordingly. If the thermostat does not execute its functions, your furnace will not know the right temperature and will stop working.

As the owner, you should ensure your thermostat is at the right settings and is not facing any technical issues. However, if you do not have the time to inspect your thermostat frequently, you can ask our technician who provides furnace installation services in Mission Viejo to install a smart thermostat in your home. A smart thermostat will adjust the settings automatically and help save money on your energy bills.

  • Check The Power Supply

Sometimes, your furnace may not turn on due to a faulty power supply. Check the main power switch of your furnace and ensure there are no cracks or faults in it. Moreover, you should check the breaker and fuse connected to your furnace to ensure they are not breaking the power supply.

If you notice any faults, you can either replace them on your own or contact a technician to replace our fuse or breaker.

  • Check The Air Ducts

As you know, the ductwork network of your home circulates warm air evenly in all areas. They help avoid hot and cold pockets in your home for a comfortable stay. However, if you do not check your ducts frequently, they may develop problems like clogs and leakages.

Clogs and leakages in ducts force the system to work harder and longer, leading to wear and tear damage. If this continues, your furnace may stop working due to overheating. Contact our technician for heating replacement services in Mission Viejo to help you.
