Cox's Old Colony HVAC & Plumbing | Local HVAC Repair in Hanover, MA

Furnace ignition failure is a common issue during our South Shore winters, often caused by a dirty flame sensor, faulty igniter, or gas valve problems. First, check your thermostat settings and ensure the gas supply is on. For safety, we don't recommend DIY repairs on gas components. Our licensed technicians are experienced with these local winter emergencies. We can diagnose the issue promptly, perform the necessary repair to restore your heat, and often provide maintenance tips to help prevent future failures during the coldest months.

Our HVAC maintenance is designed to keep your system running efficiently and prevent breakdowns. The service includes a thorough inspection and cleaning of key components, checking refrigerant levels, testing system controls and safety devices, lubricating moving parts, and checking electrical connections. For furnaces, we inspect the heat exchanger and burner assembly. This proactive care can improve energy efficiency, extend the lifespan of your equipment, and help us identify small issues before they become major, costly repairs, saving you money in the long run.
