Your heating system provides numerous warning signs when it needs furnace repair services. Timely repairs keep your home warm throughout the coldest days of the year. Below, review some of the most common signs to help you schedule repairs before the appliance breaks down or sustains more damage.

4 Issues That Indicate Immediate Furnace Repairs

1. Problems Staying On

Short cycling refers to a furnace that turns on but switches off soon after. It can indicate several issues, including an improperly sized system that heats your home quickly and then shuts down, or a cracked heat exchanger, clogged air filter, closed or blocked air registers, and faulty safety devices.

2. Higher Energy Bills

Energy bills increase during the winter; however, abnormally high costs can signal the need for furnace repairs. If your home is well-sealed from drafts and other appliances and systems are fully functional, your furnace could be wearing out from old age or expending extra energy from another issue such as a failing part.

3. Strange Odors

While a furnace typically smells when you first turn it on for the season because of dust accumulations burning off, your appliance is not supposed to emit unpleasant odors moving forward. Strange odors such as rotten eggs or burning parts could mean your furnace needs could indicate a safety issue such as a gas leak. Turn the heating system off either way until your furnace repair team arrives.

4. Odd Noises

Your heating system calls for furnace repairs when it makes banging, squealing, grinding, popping, whining, or groaning noises. There could be a loose interior component, an air leak, a loose or faulty belt, or another issue you can’t ignore.
