Keeping cool in the summer and warm in the winter isn't just about comfort — it's about maintaining a home that breathes easy year-round. Beyond merely reducing the chances of an unexpected breakdown, regular upkeep of your HVAC system significantly extends its lifespan and is easier than you might think. While experts suggest professional maintenance once or twice a year, there are some simple tasks you can perform on your own.
Monthly
Ensure outdoor components are on level ground and free of leaves, grass clippings, toys, and other debris. Maintain two feet of clearance around the unit.
Inspect refrigerant line insulation for damage and check for leaks. If repairs are needed, consult a licensed HVAC professional.
Seasonally
In warmer months, turn off the water supply to the furnace humidifier. When the weather turns cooler, replace the humidifier filter and turn the water back on.
Use high-efficiency air filters, and be sure to replace them every three months.
Yearly
Clean the AC condensation drain line with water and bleach.
Lubricate the HVAC motor and replace the fan belt if necessary.
