6 Signs Your Furnace Is Probably Dying


When a furnace dies unexpectedly, it can throw your whole world into a panic. Furnaces are expensive and the last thing you want is to be out of heat during the coldest months of the year. By planning ahead and knowing what to look for, you can often spot signs that your furnace might need repairs or be on its way to the appliance graveyard. Here are some surefire ways to know it is probably time to plan for an upgrade.

1. The Unit is Old

The average furnace has a lifespan of 16 to 20 years, according to the Department of Energy. If yours is getting close to that age, it might be time to start shopping for a new model. If you aren’t sure how old yours is, check the unit itself for a manufacturing sticker or other date. If you can’t find one, see if you can find a model number and do some research.

2. It Kicks On and Off More Frequently

If your furnace seems to be coming on more than it used to, that might be a sign that it can’t work as hard as it used to. It might not be able to distribute heat throughout the home, or the thermostat might be failing and unable to sense temperature as well. Additional resources can be found at Climate Experts.

3. It Makes Weird Noises

Every furnace has some noise, but you know what you are used to hearing. If your system has started squealing, popping, or making other unusual noises, you are probably on your way to an upgrade. You can get an inspection to be sure, but noise is usually a sure sign of age.

4. Hot and Cold Spots

If some rooms in your home are warmer than others, this might be a sign the furnace is losing its ability to distribute and force air through the home properly. If you are constantly adjusting the thermostat or dealing with random hot or cold rooms in the home, new furnace installation might be the answer.

5. Dry or Dusty Air

Stuffy or stale air in the home could be a sign of a dying furnace. The unit’s job is to help clean and moisturize the air, but as it ages it loses its ability to do this. If you notice more allergies, dust, dry skin, or static in your home, it might be the heating unit.

6. Carbon Monoxide

Cracks in the unit can allow carbon monoxide to leak into the home. Those experiencing frequent headaches, nausea, or disorientation might be suffering from exposure to this poisonous gas. Install carbon monoxide detectors and have your system inspected annually to prevent harm to your family.

Knowing what condition your furnace is in will help you prepare for what otherwise could be an impossible expense. Keep an eye on your system and if you’re not sure, feel free to call an expert for an inspection before you commit to a new furnace installation.
