HVAC Resource Guide
Heating and cooling account for nearly half of the average Western Mass home's energy costs. The good news? You don't need a full system replacement to start saving. These practical tips can lower your bills starting today.
Air leaks around windows, doors, outlets, and pipes can waste 25-30% of your heating and cooling energy. Check for drafts on windy days. Use weatherstripping on doors and caulk around window frames. Pay special attention to the attic hatch, basement rim joists, and where pipes or wires enter your home. Mass Save offers free home energy assessments that include air sealing.
Many older Western Mass homes, especially those built before 1980, are under-insulated. Attic insulation should be R-49 to R-60 for our climate zone. Upgrading attic insulation alone can reduce heating costs by 10-20%. Mass Save offers 75-100% off insulation costs for eligible homeowners.
Setting your thermostat back 7-10°F for 8 hours a day can save up to 10% on annual heating and cooling costs. Smart thermostats like the Ecobee or Google Nest learn your schedule and adjust automatically. Many utility companies offer rebates on smart thermostats.
A clogged air filter forces your HVAC system to work harder, using more energy and putting extra wear on components. Check your filter monthly and replace it every 1-3 months depending on the type. This simple step can improve efficiency by 5-15%.
Windows account for 25-30% of residential heating and cooling energy use. In winter, open south-facing curtains during the day to capture free solar heat, then close them at night for insulation. Consider storm windows or window insulation kits for older single-pane windows. These can reduce heat loss through windows by 25-50%.
A professional tune-up ensures your system runs at peak efficiency. Technicians clean components, check refrigerant levels, test safety controls, and calibrate your thermostat. Skipping maintenance is like skipping oil changes on your car. The system still runs, but not as well and not as long.
If you spend most of your time in a few rooms, zone heating with ductless mini splits or space heaters can be more efficient than heating your entire home. Close vents and doors in unused rooms (but don't close more than 20% of your vents, as this can strain your system).
