5 Common Furnace Problems and How to Fix Them
Furnace problems can be a huge inconvenience when the temperature starts to drop. Fortunately, many of the most common furnace issues can often be fixed without calling for professional repair services. Here are five common furnace problems and their solutions that homeowners should know about:
1.Dirty or clogged air filter:
The air filter in your furnace is responsible for cleaning the air as it circulates throughout your home. If the filter is dirty or clogged, then it can reduce airflow, cause a build-up of dust and dirt in the system, and increase energy costs. To fix this problem, check the filters and replace them regularly according to the manufacturer’s instructions. Doing this can help improve air flow as well as increase efficiency of the system.
2.Thermostat issues:
The thermostat controls the temperature of your home, and if it’s malfunctioning, then you won’t be able to keep your home at a comfortable temperature. If the furnace continues running after you set the thermostat or doesn’t turn on when it should, then check the battery in the thermostat and make sure it is functioning properly. If necessary, replace the battery or invest in a new programmable model.
3.Pilot light:
Your furnace requires a pilot light to ignite the gas burner. If the pilot light isn’t working, then try relighting it following your manufacturer’s instructions. If that doesn’t work, there could be an issue with the thermocouple (the safety device that shut off the gas when the flame goes out) or other components of the system. If that’s the case, then it’s best to call a professional repair service.
4.Ignition problems:
The ignition system in your furnace is responsible for starting up the burner when the thermostat senses a drop in temperature. Over time, the ignition can become worn or corroded and stop working properly. To fix this issue, you’ll need to call a professional repair service to replace the ignition system.
5.Airflow problems:
If there’s not enough air circulating through your home, then it could be due to a blocked or damaged ductwork or fan motor. Check the motor for signs of wear and tear or damage. It is best to call a professional repair service to inspect and clean your ducts or repair or replace the fan motor.
Contact a Professional
If the problem is too complicated for you, then it may be time to call in a professional. Other times that require a professional include when the furnace has been running inefficiently, or if it is more than 10 years old and needs an overhaul. Additionally, if you are having difficulty identifying the source of the issue, a professional can help diagnose it accurately.
Taking the time to address common furnace problems can save you a considerable amount of time, money, and stress in the long run. It is recommended that you have a professional inspect your furnace every year to ensure it is functioning properly and safely. Doing so can help prevent potential issues from getting worse and make sure your home stays comfortable all year round. If you ever suspect a problem with your furnace, contact an HVAC professional for assistance.
