Frequently asked about furnace repair
Why does my furnace blow cold air after starting?
The most common cause is the thermostat fan setting being on ON instead of AUTO — the fan runs continuously even when the burner isn't firing. Other common causes: dirty flame sensor, closed gas valve, or a tripped high-limit switch from a previous overheat. A technician can confirm which.
Is it safe to keep running my furnace if it short-cycles?
Short-cycling (turning on and off repeatedly) usually means the heat exchanger is overheating, the flame sensor is dirty, or the airflow is restricted. It's not immediately dangerous but it stresses components and reduces efficiency. Call a technician promptly — running it that way can damage the heat exchanger or trip the limit switch permanently.
How often should a furnace be serviced?
Annually, ideally in late summer or early fall before the heating season. A standard service includes burner cleaning, flame sensor cleaning, gas pressure check, and limit switch test. Catching a flame sensor issue in October beats discovering it at 2 AM in January.
Do you repair gas, oil, and electric furnaces?
Yes — gas (natural and propane), oil, and electric furnaces. When you call, mention the fuel type so the dispatcher can route to a technician with the right parts on the truck.
