Warning Signs You Need Furnace Repair

Updated: October 2023

Some signs of furnace repair are obvious, such as when your furnace won’t start. However, other signs that are repairs are needed aren’t always as easy to notice. Keep the following signs of furnace repair in mind, so your home will stay safely heated all winter long.

Unusual Increases in Utility Bills

Gas and electric bills normally increase a bit in winter when you run your furnace. A steep increase could be a sign of trouble, though. If you’ve been noticing any significant increases in your utility bills, have an HVAC technician check your furnace to see if it’s working properly.

Odd Noises

Some furnace sounds are normal, such as the noise it makes when it starts up and blowing noises. Other noises could indicate that there is something wrong with your furnace. If you’re hearing a squealing sound, banging noises or rattling, it’s important to schedule furnace repair. In some cases, a simple repair can stop the noise, such as tightening a loose component. In other cases, though, you might need more serious repairs done.

Weak Air Flow

If your furnace turns on but only blows a small amount of air, this is a sign that you need to have repairs done. This can happen if there is a problem with the fan, motor, belt or other parts of your furnace. Since issues that cause weak air flow can range from minor to serious, you should have a professional HVAC technician check your furnace and make the needed repairs.

Thermostat Problems

Your thermostat should be in good working condition, or your furnace won’t know how much heat your home needs. If you run into problems with your thermostat, replace the batteries first. If the problem continues, you’ll need to have repairs done to make sure that your furnace is able to properly heat your Charlotte home.

Frequent Cycling

Your furnace shouldn’t be turning on and off on a frequent basis. This problem, known as over cycling, means that there’s a problem with your heating system. HVAC technicians can identify what is causing this to happen and make repairs.
