Check your air filter — a severely clogged filter reduces heat output dramatically. If filter is clean, call a technician to inspect burners and heat exchanger.
Every Manhasset service call is a little different because home age, insulation, equipment location, duct design, and daily usage all affect how an HVAC system behaves. Nassau County homes often have tighter mechanical spaces, older ductwork, finished basements, additions, and mixed-age HVAC equipment that need careful diagnosis.
For heating problems, we check ignition, safeties, thermostat demand, burners, blower operation, venting, fuel supply, and whether the system can run safely through a cold night.
