Consider installing new heating equipment early in the season: spring is often the best time to invest in a home heating system, since manufacturers usually offer great off-season incentives and convenient installation appointment times are more readily available.
Consider having your annual tune-up to avoid the late springtime rush.
If you’re using your heating system, set your thermostat at 68 degrees when people are home for the best balance of comfort and energy savings; lower the temperature when no one is home, or when people are sleeping to maximize savings. Once cooling season arrives, target a thermostat setting of 78 degrees, raising temperatures when when people are home.
When using your HVAC system, close vents in unused rooms
Clear obstructions from vents to keep air moving
Check your HVAC filter once a month, changing or cleaning it as necessary
When using your HVAC equipment, keep doors closed between conditioned and unconditioned spaces; check and replace seals around interior doors to keep conditioned air from escaping
Check door sweeps to make sure they are blocking drafts and keeping conditioned air inside your home.
Check caulking on window frames to prevent conditioned air from escaping
If you have a whole house generator, have it professionally serviced; run it at least once every three months to keep it in working order (increase that frequency to once a month during the cold winter months to keep parts lubricated)
Make sure you have enough propane to last at least one week in the event of a springtime power outage (if you don’t, schedule a propane delivery).
Consider resetting the temperature of the water heater thermostat to 120 degrees (default settings are often 140 degrees) to get the best balance of comfort and energy savings; for every 10 degrees you lower the temperature, you’ll save 3-5 percent on your bill, says the DOE. Keep the temperature at 140 degrees if someone in your home suffers from immune deficiency.
