Heating, Furnace & Boiler Repair — Frequently Asked Questions

Do you repair boilers as well as furnaces in New Canaan?

Yes. Many homes in New Canaan and lower Fairfield County still rely on hot-water or steam boilers, often with multiple zones or radiators. We service gas and oil boilers, furnaces, heat pumps, ductless systems, and the controls that tie them together.

What should I do if I have no heat during a Connecticut cold snap?

Call right away — especially if outdoor temperatures are near or below freezing. A no-heat call in winter is about comfort and preventing frozen pipes. If it is safe, check your thermostat, replace a clogged filter, and verify the emergency switch and breaker are on, then let us handle the diagnosis.

Why is my furnace blowing cold air?

The usual causes are thermostat fan settings, a dirty flame sensor, ignition failure, airflow restrictions, or a safety limit shutting the burner down. On heat pumps, cold air can also mean a defrost or auxiliary heat issue. We test the full sequence of operation so the real cause gets fixed.

How much does heating repair cost in New Canaan?

Most heating repairs in the New Canaan area fall between $185 and $850 depending on the failed part and system type. Boiler controls, circulator pumps, oil burner issues, or after-hours calls can run higher. We charge a $109 diagnostic fee that is waived when you approve the repair.
