A heating problem can start at the thermostat, furnace, boiler, electrical controls, airflow system, or heat-distribution equipment. Lancaster Brothers inspects how the complete system operates to find the source of the failure. Our technicians repair gas and electric furnaces experiencing ignition problems, failed blower components, restricted airflow, electrical faults, repeated shutdowns, and weak or uneven heating. We also service boilers with circulation problems, pressure changes, leaks, faulty pumps, ignition failures, or controls that aren’t responding correctly. When your existing equipment can still deliver dependable service, we repair it rather than pushing an unnecessary replacement.
