Signs Your Furnace Needs Repair

Sometimes, your furnace will give you clues that something is about to break down, while other times, it catches you completely off-guard when you wake up to a cold house in the morning. Here are a few signs to watch for that indicate you probably have a problem with your furnace that will require repairs.

  • Unusual odors. Most of us are familiar with the dusty smell that typically accompanies the first few uses of the season. However, if you smell something like rotten eggs, it could mean there is a gas leak. It’s best to get everyone outside and call your gas provider immediately.
  • Loud noises. If you hear loud metallic banging and clanging noises, it may be alarming. Typically, the cause of these noises is a broken fan blade or another component, and if caught early, usually only amounts to a minor furnace repair.
  • Running continuously. If your furnace runs continuously but still fails to keep the house warm, there are several possible reasons. There could be a problem with the thermostat, or there could be a leak in the ductwork. A professional will be able to diagnose the problem.
  • Cycling on and off. If your furnace turns on and then goes off almost immediately (called “short cycling”), there are various problems that could be the source. The reason that your furnace turns off so quickly after turning on is thanks to the safety system working properly.
  • High energy bills. If you notice that your heating bills are significantly higher than they have been, consider getting your furnace inspected. Something could be causing your furnace to work too hard and driving up your energy use.

FAQ About Furnace Repairs

Why is my furnace making noise?

A noisy furnace can be caused by different problems. First, it depends on what kind of noise it’s making. A whistling noise may indicate a gap in the duct or a clogged filter, while rattling noises could indicate a loose screw in the ducts. If you hear banging, it could be that somewhere there is a weak spot in your duct work, or an issue with the gas ignition. An HVAC professional will be able to diagnose any unusual sounds made by your furnace and repair the source of the problem.

How often does the furnace filter need to be changed?

You should change your furnace filter every 3-6 months, depending on how thick it is. Thinner filters will get dirty faster and should be changed sooner. Regularly changing your furnace filter will not only reduce allergens in your home, but it will also help your furnace to run more efficiently.

Signs Your Furnace Needs Repair

You can’t always know ahead of time when furnace repair is necessary.  Sometimes you toss back the blankets and wake up to a frigid home.  Other times, the signs are subtle.  When you know what to look for, you may be able to avoid furnace failure, costly repairs, or possible replacement.

  • Unusual odors coming from your furnace can be frightening.  If you smell gas, check your pilot light.  If you see a flame that’s blue, there may be another issue with your lines.  Evacuate your home and contact your local gas provider immediately.
  • Loud noises and racket during operation is not a good thing.  Fortunately, it’s often indicative of a broken fan blade, or other component, which may be an easy furnace repair if caught early.  For unusual noises coming from your furnace, contact W. F. Smith, Inc, Heating & Air Conditioning.
  • If you find your furnace is continually running, yet not able to maintain a reasonable temperature, you need to call us for furnace repair.  You may need to replace your thermostat, or failure to maintain a comfortable temperature could point to a leaking duct or pilot light problem.
  • A furnace that turns on, then off, almost immediately, could indicate a problem with your motor, your thermostat, or your electrical system.  Give us a call to remedy your furnace cycling problem.
  • Higher-than-normal bills without unusually cold temperatures mean it’s time to schedule an inspection.  There could be many reasons for your less-than-efficient heating bills and putting off repairs could cost you much more in the long run.
