Summer heat is quickly fading, and before you know it, you will need to turn on your furnace. Since the heating system likely had not been used for a few months, it is best to get it ready for the colder months before the temperatures drop to ensure the system doesn't fail when you need it most. Before you contact a heating contractor to inspect your furnace for potential problems, here are a few steps to take to prepare it for winter. 

What Are Some Winter Preparation Tips for Furnaces?

1. Replace Filter

Your air filter should be changed often to prevent the airborne particles it traps from circulating through your home and clogging the HVAC system. Filters that are 1- to 2-inches thick can be swapped out every three months, and 4-inch filters can be changed bi-annually. Electrostatic filters, however, can be washed, dried, and reused.

2. Check Thermostat

Your thermostat controls the furnace, so you should test it to ensure it functions well. Otherwise, the heating system may not work efficiently. To test, turn the thermostat up a few degrees and monitor how the HVAC system responds. If it doesn't turn on within a minute, you may need a heating contractor to check its connections. 

3. Clean Vents

Over time, dust, dirt, and allergens like pollen and pet dander will settle inside air vents and ducts. If these components get too dirty, they can impede airflow into the home from the furnace. The debris can also reduce the air quality inside the house, which can be problematic because you may not want to open windows during the winter. You can use a vacuum or damp cloth to clean air vents and ducts.
