8 Signs Your Furnace Needs Fixing
Whether they are old or new, all furnaces may require repairs at some point. After heavy use over time they can become damaged. Even something as simple as changing your air filters can make a huge difference in how well your furnace runs. The best way to avoid furnace repairs is to schedule regular maintenance.

Even with maintenance, damages occur from regular use. Take a look at our list of eight signs that your furnace needs to be repaired:
1. Strange OdorsBecause furnaces are constantly hot and emitting gases, a strange odor is an easy way to tell that something is wrong. An acrid smell as if something is burning could mean that the dust and debris that settles on top of your furnace is being burned. The easiest way to fix this problem is to turn your furnace off, wait for it to completely cool down and then give the system a good wipe down with a wet cloth. The smell of rotten eggs, however, is not as easy to fix. Gas companies often add a sulfur smell to gas so that leaks are easily identified. If you think that you have a gas leak, be sure to call your gas company or the fire department to shut off your gas immediately and evacuate your home.
2. Higher Than Normal Energy BillA large spike in your energy bill could be a sign that your furnace needs to be repaired. When HVAC systems have to work harder due to some kind of issue it is often reflected in the energy bill. The only problem with relying on your energy bill to tell you if something is wrong with your heating system is that it means weeks have gone by without the system being repaired. Over time, damage can become worse and sometimes lead to the need for replacement.
3. Discolored Pilot LightWhen you check your furnace, be sure to take a look at the pilot light. The light should be a bright blue. If it is a red, orange or yellow color then the burners may be dirty. The easiest way to take care of this problem is to clean the burners. While some may feel comfortable doing this themselves, you can also hire an HVAC technician to do it for you. The problem may not lie with dirty burners but with a fuel deficiency. It’s always a good idea to call a technician when it comes to pilot light issues.
4. Abnormal SoundsIt’s normal for your furnace to make noise when it is turned on. However, this noise should be more of a white noise sound rather than a clanging or screeching. A clanging noise may mean that a piece has come loose inside of the furnace. Screeching could mean that the system needs to be lubricated. No matter what kinds of noise your furnace is making, be sure to take note of it and call a professional for HVAC repair.
5. Inadequate HeatWhen furnaces are broken or damaged, they may stop producing adequate heat. There are a few different reasons why this could be happening:
- Air filter is clogged and needs to be replaced
- Broken heat exchanger
- Wiring issue or problem with the breaker box
- Damaged or broken blower belt and fan
- Damaged burners or pilot light
