— Gas Heating Warning Signs —

When Your Gas Furnace Needs Repair

Call for service when a gas furnace produces little or no heat, starts and stops repeatedly, makes new noises or leaves rooms unevenly heated. A sudden change in operation often points to a control, ignition, airflow or mechanical problem that should be diagnosed before it becomes a complete breakdown.

If you smell gas, hear a carbon-monoxide alarm or believe combustion is unsafe, leave the property and contact the gas utility or emergency services from a safe location. Do not operate the equipment until the hazard has been addressed.

— Accurate Troubleshooting —

Gas Furnace Problems We Diagnose

Gas-heating failures can involve the thermostat, igniter, flame sensor, burners, limit controls, blower assembly, venting, electrical components or airflow through the system. Similar symptoms can have different causes, so replacing a part based on guesswork can waste time and money.

Proto Home Service evaluates the system, explains the diagnosed problem and reviews pricing before approved repairs begin. The goal is to restore reliable heat while addressing the condition that caused the failure.

Urgent Gas Heating Repair

A furnace that will not start during cold weather, shuts down repeatedly or shows signs of unsafe operation deserves prompt attention. Call (617) 842-9104 for a no-heat emergency; calling is faster than submitting the online form when service is urgent.
