Your furnace is a critical part of your Milton, Delaware, home, and responsible for your wintertime comfort. Because you rely on your furnace during the cold winter months, reducing the risk of breakdown should be a major concern. Luckily, your furnace is likely to give you plenty of warning before a breakdown, as long as you know how to read the signs.

Loud or Unusual Noises

Your furnace should make minimal noise once it is running and should never sound disruptive. If you notice new or unusual noises coming from your furnace, it could be a sign that it is in need of repair. Squealing can mean that belts are frayed. Clanking can mean bearings or other components might have come loose. Clicking can be a signal of electrical or ignition problems. You should report any new noises to your HVAC company so they can inspect it.

Smells and Odors

Aside from a slight smell of burning dust when your system is first started up for the season, your furnace should never smell. Chemical odors can be a sign of a cracked heat exchanger. Burning smells could mean bad wiring. The smell of rotten eggs is a dangerous sign of a gas leak. Whatever the smell, it should be investigated.

Constant Running

Your furnace is designed to turn on when your thermostat senses that the temperature is lower than the desired temperature, and turn off when it reaches that level. It still should shut off from time to time, even when it is cold outside. A continually running furnace could be a sign that your furnace is too small for your home. It could also be indication of a problem that is making it work less efficiently.
