Without expert knowledge, it’s difficult to tell if your heater requires repairs or is simply developing some harmless quirks. There are some signs, however, that indicate an immediate need for professional service. Below are some of those signs.
Cold spots, temperature swings, and other signs of uneven heating could indicate a need for professional heating repair. Before you make that call, however, check the vents in the room where you are experiencing uneven heating. If the vents are clear and unobstructed, make sure that warm air is flowing through them. If it isn’t, you may have a blockage in your ducts. You should call a professional to take a look at that point.
Short-cycling occurs when your heater keeps rapidly turning on and off throughout the day. There are a number of possible causes for this, but the most common is an oversized heating unit. When an oversized heating unit starts, the excessive heat output causes the system to think that the unit is overheating. Safety measures trigger as a result, shutting down the heater to prevent a fire. The unit then restarts because the thermostat is still set to “heat,” and the cycle continues indefinitely. There are other things, like a dirty air filter, that can also cause short-cycling. You’ll need an HVAC technician to diagnose the root of the problem, however.
Pilot Light Won’t Stay Lit
In gas powered systems, the pilot light is the small flame that lights the burner for the furnace or boiler. Without this pilot light, your heater will be unable to turn on. Pilot lights going out is a fairly common occurrence, and not a major concern. When the pilot light refuses to stay lit, however, it is a sign of a more serious issue. A bad thermocouple is often to blame for this kind of problem. This sensor is what is responsible for controlling the gas flow to the pilot light. When it is malfunctioning, the thermocouple can shut off the gas flow to the pilot light, suffocating it.
