Marin evenings start cooling in September, and the first heater test of the season is usually a surprise. A short round of practical fall prep can save money on utilities over the next months without leaving you shivering on chilly autumn nights.
Check Thermostat Settings
The biggest savings come from your thermostat schedule. Set daytime temperatures around 68 degrees when you are awake and home, and drop it 7 to 10 degrees at night and when the house is empty. That adjustment alone can cut heating costs by about 10 percent a year, and AARP has a good primer on other low-cost fall home changes.
If your thermostat is the round dial from 1985, a basic programmable model installs in twenty minutes. If new tech feels overwhelming, ask a grandkid or a neighbor. It is not complicated once someone shows you where the wires go.
Wear a sweater. Long sleeves and warm socks let you set the thermostat two degrees lower without noticing.
Seal the Small Leaks
Older homes have character, and they also have gaps. Walk around on a breezy morning with a stick of incense or a lit candle, and watch where the smoke bends. Doors, windows, outlets on exterior walls, and attic hatches are the usual suspects.
Fixes are cheap. Weather-stripping tape for the doorframe. A door sweep along the bottom. Foam gaskets behind the light switch and outlet plates on exterior walls. Use rope caulk for old single-pane windows that leak, but you don't want to replace them this year.
Close the flue when the fireplace is not in use. An open damper is a chimney-sized hole to the outside.
Heating System Fall Checkup
Change the furnace filter. Do it now, and do it again in December. A dirty filter forces the system to work harder and burn more energy for the same warmth.
If you have a forced-air system, make sure furniture and rugs aren't blocking any floor vents. If your heater is 15 years old or more, book a tune-up with a local HVAC company before the first cold snap.
If you're still using baseboard electric heaters, keep the fins clean and free of dust. That alone improves efficiency noticeably.
Water and Lighting Add Up
Set the water heater to 120 degrees. Higher settings waste energy and increase scald risk, especially for older skin. Wrap an older water heater tank in an insulation blanket if you can find one; it saves about 4 percent per year.
Swap the last incandescent bulbs for LEDs. LEDs use about 75 percent less energy and last a decade. Start with the fixtures you use daily.
Run the dishwasher and laundry with full loads, not half loads, and skip the heated dry cycle—small habit shift.
