What Are Common Reasons My Heater Is Not Working in My House?

Common heater failures usually trace to thermostat settings or batteries, a tripped breaker, a clogged air filter, ignition or pilot issues on furnaces, low boiler pressure or failed circulators, or a heat pump stuck in defrost or low on charge. We repair furnaces, boilers, heat pumps, and radiant systems in Nashua and nearby areas. Upfront pricing and a 2-year parts and labor warranty back our work.

Quick checks:

• Set thermostat to Heat and raise 3–5°F.
• Replace/clean the filter.
• Check the breaker and furnace switch.
• Verify boiler pressure and pilot status.
