Winter Readiness Checklist

The heating season in New England begins in November and peaks in January–February. August through October is the window to prepare. Here are eight essential steps to ensure your heating system runs reliably through winter.

1. Schedule a Seasonal Tune-up

Before October 31, call and schedule your pre-winter system inspection. A tune-up includes boiler output measurement, thermostat calibration, radiator testing, and sediment flushing if needed. This is not optional; it's the single best predictor of winter reliability.

Don't wait until November 1—contractors are overwhelmed with emergency calls once cold weather arrives.

2. Test Your Thermostat

Set your thermostat to 65°F and verify that your heating system responds within 5 minutes. Listen for boiler ignition and burner operation. If the system doesn't respond, or if it cycles on and off frequently, call for service immediately—don't wait for winter.

For older mercury thermostats, check that the tube is level (use a level tool) so the mercury contacts the contacts properly.

3. Inspect Radiators for Cold Spots

Feel each radiator with your hand, top to bottom. The entire surface should be warm (not necessarily hot). If you find a cold zone—the bottom is cold while the top is warm, for example—you have a trapped-air problem or a failing trap. Call for radiator balancing before the season starts.

4. Check Boiler Room Safety

Ensure your boiler room is free of clutter. Keep a 3-foot clearance around the boiler for air intake and service access. Check for water leaks (small drips are normal; streams are not). Verify that the flue pipe is not blocked by bird nests or debris (look outside at the roof vent).

If you smell combustion odors or see soot, call for service immediately.

5. Top Off Your Fuel Tank

If you use heating oil, schedule a delivery by October 15 so you start the season with a full tank. A full tank is insurance against unexpected price spikes and ensures you won't run out during a cold snap (running an empty tank can draw sediment into the burner).

For natural gas, ensure your account is active and your billing information is current. Request an automatic-payment arrangement if available.

6. Bleed Radiators (Steam Systems Only)

If you have steam radiators, check that the airbleed valve (a small metal screw) on each radiator is functional. A working airbleed will emit a hissing sound briefly as air escapes, then stop. If a radiator has a stuck airbleed, schedule radiator service to have it cleaned or replaced.

7. Winterize Windows and Doors

While you're preparing your heating system, take 30 minutes to inspect windows and doors. Caulk any gaps between the frame and masonry. Replace worn weatherstripping. These improvements reduce heating load and ensure your thermostat doesn't work overtime.

8. Program Your Thermostat

Set your winter heating schedule. Most homeowners find comfort with 68°F daytime and 62°F overnight. If you're away during the day, set a lower daytime temperature. A 6°F reduction overnight saves 10–15% in heating costs.

Avoid setting the thermostat above 72°F—it won't heat faster and will waste fuel.

Bonus: Create a Service Record Folder

Keep receipts and reports from all HVAC service visits in one folder (digital or paper). Include boiler pressure readings, efficiency measurements, and any work performed. This history is invaluable for future technicians and for understanding long-term system trends.

One More Thing

If you experience heating loss once winter arrives, don't delay calling for emergency service. The longer you wait, the longer your building sits unheated and the greater the risk of frozen pipes. Our emergency dispatch is 24/7 from November through March.
