ToggleCheck and replace your furnace filter.
A clogged furnace filter will no longer filter your air supply and will greatly reduce the efficiency of your furnace. Your furnace filter should be checked regularly to make sure it’s not blocked.
Inspect the heat exchanger for cracks, rust or other damage.
A crack in your heat exchanger can cause a burner or pilot light to be blown out, which will result in a no-heat situation. A larger crack could upset a steady flame in your furnace or cause the burner flames to flicker out of the burner opening and in worse-case-scenarios, it can cause death after leaking poisonous, odorless carbon monoxide gas into the house. If you suspect a crack have it replaced.
Check the venting system for leaks, holes or blockages.
Your vents could be blocked by improperly installed ductwork insulation that has gotten in, blown pieces of your old furnace filter or other debris. If it’s not cleared could impact your efficiency or cause a room to not heat up at all. Having a heating contractor conduct a full duct cleaning every fall will ensure there are no clogged vents and that you’re running at maximum efficiency.
Inspect the burners for damage or to see if they need to be cleaned.
If your burners look dirty and are not firing up in proper sequence they probably need to be cleaned out. You can clean the burners using a vacuum or toothbrush.
Make sure all your heating vents are open and unblocked.
Remove furniture or other items from around your heating vents to ensure evenly distributed airflow. Clean and remove dust from vents or along baseboard heaters.
Upgrade your heating system.
If you’re still running your 1970’s gas furnace you can be losing some serious energy. Modern high efficiency gas furnaces can achieve efficiency ratings as high as 97 percent. Replacing your old furnace could literally cut your natural gas use in half and result in great savings this winter. Besides the energy savings, a new furnace will ensure your families safety and eliminate the need for costly furnace repairs.
