How to Prepare Your Heating System Before a Connecticut Winter

A heating system that fails in January is not just uncomfortable — it can freeze pipes and cause serious damage. A one-hour fall checkup prevents most of that.

Connecticut winters routinely push below zero. A heating system that is marginal in October becomes a liability in January. The fix is simple: a fall checkup before the first hard freeze.

Start with the filter. A clogged air filter on a forced-air system makes the blower work harder and cuts efficiency by 15 to 20 percent. Replace it every 90 days during heating season.

Bleed your radiators. If you have a hot-water baseboard or radiator system, trapped air creates cold spots and makes the boiler run longer to compensate. Bleeding is a five-minute job with a radiator key.

Test the thermostat. Switch it to heat and set it five degrees above room temperature. The system should kick on within a minute. If it doesn't, the thermostat or the igniter may need attention.

Check the flue and venting. Birds and small animals sometimes nest in flue pipes over the summer. A blocked flue is a carbon monoxide risk. Look for obstructions or call us to do a proper inspection.

Schedule a professional tune-up. A technician will check burner efficiency, test safety controls, inspect heat exchangers for cracks, and clean the combustion chamber. This is the step that catches problems before they become emergencies.
