6 Signs Your Furnace Needs Repair

As fall and winter approaches you’ll likely be firing up your heating system for the first time in months. As you get it going it is important to pay attention to how it acts, as it may provide you with some signs that it needs repair. If you encounter any of the following issues you will want to contact a professional HVAC company as soon as possible to ensure that you don’t go without heat this fall and winter.


If the inside of your home’s windows are coated with condensation there is a good chance you’re suffering from some sort of heating system malfunction.


If you feel cool drafts in a particular area of your home it is likely because the furnace is no longer heating the whole house. This may be resolved by something as simple as cleaning vents, but it could be a sign of a larger problem. An HVAC expert will be able to perform diagnostics and repair the issue.

Furnace Takes a Long Time to Warm Up

If you’re waiting and waiting for the heat to turn on there may be an issue with the pilot light, thermostat or fan motor.

Yellow Pilot Light

A yellow colored pilot light indicates a poor gas combination in your furnace and may mean there carbon monoxide is present. A pilot light that has the correct gas mixture should be burning a blue color.

High Electric Bills

If your electric bills seem to be getting higher throughout the cooler seasons because you keep on cranking the heater up there is obviously some sort of inefficiency issue that needs to be addressed by a professional heating technician.

Unusual Sounds

If your furnace sounds like it’s crying for help, it probably is. The creaking, banging and whining noises are a sure sign of trouble ahead. The sooner you call someone to take a look the better, as these noises usually indicate a loose belt or ignition problem.
