HVAC Resource Guide
Regular maintenance is the single best thing you can do to extend your HVAC system's life, prevent breakdowns, and keep energy bills in check. Here's a practical season-by-season guide for Western Massachusetts homeowners.
Before Western Mass winters hit, schedule a professional furnace tune-up. Replace your air filter (or clean it if reusable). Test your thermostat by turning on the heat and verifying it reaches the set temperature. Check carbon monoxide detectors and replace batteries. Clear any debris from around outdoor units. Bleed radiators if you have a hot water heating system.
Check and replace your air filter monthly during heavy heating season. Keep vents and registers clear of furniture, curtains, and rugs. Monitor your energy bills for unexpected spikes that could signal a problem. Keep the area around your furnace clear for safety and airflow. If you have a heat pump, make sure snow and ice aren't blocking the outdoor unit.
Schedule a professional AC or heat pump tune-up before summer arrives. Clean or replace your air filter. Inspect your outdoor condenser unit, clearing away leaves, grass, and debris. Test your AC by running it for 15-20 minutes and checking that cool air reaches all rooms. Consider having your ductwork inspected for leaks.
Replace your air filter every 30-60 days during heavy cooling season. Keep your thermostat at 78°F when home and higher when away to balance comfort and efficiency. Make sure your outdoor unit has at least 2 feet of clearance on all sides. Use ceiling fans to supplement your AC and reduce the load on your system.
Homeowners can handle filter changes, thermostat checks, keeping units clear, and visual inspections. Leave combustion testing, refrigerant checks, electrical inspections, and ductwork repairs to licensed professionals. A professional tune-up typically costs $80-$150 and can prevent repairs that cost 10 times that.
Don't wait for your next scheduled maintenance if you notice: unusual smells (especially gas or burning), water leaks around your system, ice forming on your AC unit or heat pump, the system won't turn on or stay on, or you hear grinding, screeching, or banging sounds. These need prompt professional attention.
