Signs You Need Furnace Repair

Most homeowners will only call for furnace repair when their furnace has completely stopped working. However, there are other signs to look for that indicate a malfunctioning furnace. In addition to mechanical failure, there can be various indications that you need furnace maintenance or possibly furnace replacement. If your furnace displays one or more of the signs below, it may need repair, so call us as soon as possible.

Furnace Repair Signs

Your furnace makes strange noises.

Most furnaces aren’t usually completely silent, but if you hear unusual banging, whining, or groaning noises from your unit, it may be a sign your furnace needs repairs. Unusual noises could mean it has difficulty igniting, has a loose belt, or has a faulty part that’s on the verge of breaking. If you hear these types of sounds, contact John Nugent & Sons for furnace repair in Northern Virginia.

Your energy bills have suddenly increased.

If you are close with your neighbor, ask them how much their electrical bill is typically. If your bill seems unusually high, it may be due to a faulty or defective air distribution fan. The high electricity bill may also be due to inefficient performance as a result of leaky ducts or a clogged air filter. Call us, we’ll come and inspect your furnace to make sure it is working properly. If it needs repairing or general maintenance, we can take care of that as well.

You keep having to turn up your thermostat.

What do you when you’re cold in your home? A common response is to set the thermostat to a higher temperature. As the situation becomes worse, even the maximum setting cannot deliver the right amount of heat. You may have a defective thermostat, a faulty pilot ignition device, or even leaking ducts. Give us a call so we can figure out what’s going on. Don’t stay in the cold this winter, contact John Nugent & Sons for furnace repair in Northern Virginia.

Your pilot light is yellow.

The color of the flame from a gas furnace can be used to diagnose problems the unit may have. If it is in proper working order, the flame should be blue–with only very little yellow at the tip of the flame’s inner core. If the flame is mostly yellow or orange, this signifies a major, and potentially dangerous, problem. If you observe this, call us immediately.

Your furnace takes too long to turn on.

Does your furnace take an unusually long time to turn on and get started? If this is the case, your unit may have a faulty thermostat, defective wiring, or an issue with the pilot light ignition. There may also be an issue with the fan motor. These problems generally become worse over time, so it is better to get them repaired now rather than wait until later.
