Furnace Problems – Answered

Why does my furnace whistle?

Your furnace is likely whistling because air is escaping through a small opening where it should not be. This can happen anywhere in your furnace system; loose register covers, loose duct connections, and newer, stronger fans are common causes. Remember to be careful when working with your furnace (especially your fan), we recommend you rely on a professional to fix your problem.

Why does my furnace leak water?

Furnaces may leak water for a number of reasons, common causes include: damaged or missing insulation, faulty or missing pumps, clogged or frozen drains and pans, dirty or faulty coils, and damaged or badly-fitted pipes. If you cannot identify the problem you should contact a technician for a professional opinion.

Why is my furnace filter black?

A black furnace filter is a very bad sign and you should immediately check for carbon monoxide in your home because the gas is colorless, odourless, and deadly. This is not, however, the only reason for a black filter. Other common causes include dirt, debris, or soot in the air, mold in your ducts, or improper combustion in your furnace.

Why is my furnace loud?

Many problems can cause a loud furnace. For example, whistling indicates escaping air, a banging sound can indicate a weakness in the ducts or a burst of flame on ignition, and rattling indicates unsecured parts. There are many answers and you should rely on a technician’s opinion if you cannot easily identify the problem yourself.

Why does my furnace beep?

Your furnace beeps to try and tell you something. This can be part of normal operations, or to indicate a problem, and the message depends on the make and model of your machine. Check your owner’s manual or contact a technician (with your machine serial number on hand) to find out what your furnace beeps mean.
