If you live in a part of the country that gets cold in the winter, you will want to ensure your heating system is working properly before the freezing weather hits. Some tasks you can do yourself to ensure the heating system is ready for winter include cleaning or replacing your filter, checking your blower belt for damage, and making sure the blower doors are sealed.

You should also turn on your heating system to make sure it functions properly. If you notice any of these three signs, you may need to contact a professional about heating repairs.

1. The Heating System Produces Strange Smells

When you turn on your heating system for the first time, you might notice the smell of fuel or a dusty smell. These odors should eventually go away. If you suddenly smell a strange odor while your heating system is running or there is a smell that doesn't go away, the system might be in need of repairs.

Some smells to be aware of and possible causes include:

  • Musty. There could be mold on the filter.
  • Oil. The filter might be clogged or there is an oil leak.
  • Electric. There might be malfunctioning electrical components.
  • Sulfur. There is a gas leak.

If you have a smell you can't identify and it doesn't go away, you should contact someone for heating repairs.

2. The Heating System Makes Odd Noises

Your heating system should be fairly quiet. If you notice odd noises, your heating system may require heating repair. If the heating system makes a loud noise when it starts, it could be due to delayed ignition, which means there is a buildup of unburned oil in the fire box chamber.

Some noises to be aware of and possible causes include:

  • Whistling. There are gaps in the ducts or a clogged filter.
  • Rattling. The heating system has loose pieces of equipment.
  • Banging. The heating system has broken components.

If your heating system makes persistent noises, you should get it inspected.

3. The Heating System Isn't Producing Enough Heat

When your heating system fails to keep your home warm, it probably means it's not producing enough heat. Some of the most common reasons for this include:

  • Clogged filter
  • Tripped circuit breaker or blown fuse
  • Dirty furnace burners
  • Furnace blower that needs lubrication
  • Ignition system that is not functioning properly

One more obvious reason the heating system is not producing enough heat is that the thermostat either has not been turned on or is faulty.
