How to Maintain a Furnace During the Winter

A functional heating system should work efficiently, allowing you to heat your home and maintain a comfortable temperature. If your unit is not working correctly, you could call a qualified technician for a furnace repair or checkup. Here are some ways technicians help you maintain a furnace during the winter:

Change or Clean the Air Filter

A working air filter traps dust, dirt, and pollen, preventing them from entering the furnace system and changing the indoor air quality. When the filter becomes clogged, airflow becomes restricted, which might cause your heating system to strain. During a furnace repair, a technician cleans the air filter and returns it if it is still in good condition. An alternative solution for a damaged air filter is to remove it and install a new one that functions efficiently. Once the new or cleaned filter is in place, the technician should turn on your heating system to determine if airflow has improved.

Inspect and Clean Vents and Ducts

When ducts and vents get blocked, it forces your furnace to work harder, which can lead to overheating. A technician should remove each vent cover and clean it, using brushes and air pressure to get rid of dirt. They may use soap and water for additional cleaning in areas like kitchens where grease buildup might be present. To clean ducts, professionals use a vacuum or other specialized equipment to loosen up the particles and eliminate them. After cleaning, a technician reassembles the components and runs the furnace to check if there are more blockages.

Check for Carbon Monoxide Leaks

Checking for carbon monoxide leaks helps keep indoor air free from harmful gases, maintaining a healthier home environment. During an inspection, a technician checks for potential sources of leaks, such as cracks or corrosion in the furnace. This professional also inspects the heat exchanger for damage since it could become a source of carbon monoxide leaks. If the heat exchanger has minor cracks, a technician seals it to prevent further erosion. For severely damaged components, technicians might suggest replacing them to help promote safe and effective functioning.

Lubricate Moving Parts

Moving parts like the motor and blower bearings create friction and can cause wear and tear on your heating unit. Lubricating these components allows them to move more smoothly and reduces the wear when sand or dirt scratches the material. Technicians may apply lubricant to shafts and pulleys to allow them to operate quietly and efficiently. To also prevent dust and grime from settling, a thin layer of lubricant may be added between moving parts. After lubricating different parts, a technician should test the system for excess noise, vibration, or friction.

Book an Appointment for Furnace Repair

If your furnace struggles to heat your home or makes loud noises, it might be time to schedule furnace repair. During this process, a technician inspects your heating unit for broken parts, trapped debris, or pests. To keep your home warm during the colder season, call a trusted heating and cooling company for maintenance.
