What to Do When Your Furnace Won't Heat Up

If you're like most people, you rely on your furnace to keep your home warm and toasty. Unfortunately, furnaces aren't immune to malfunctions and can shut down or stop working at any time. If you discover that your furnace isn't heating up like it should be, you must take steps quickly to identify the problem and either repair it or replace the unit altogether.

Common Issues With Furnaces

When faced with a furnace that won't heat up, it's important to understand the most common issues that can prevent a unit from correctly operating. It could be something as simple as a dirty air filter that needs to be replaced or a more complex issue such as a malfunctioning motor or broken thermostat. The best way to identify the problem is to inspect the furnace and its components.

You may find that the blower motor isn't working, in which case a professional repairman would need to be called in to replace the part. If the problem is more complex, such as a severely worn belt or an electrical connection that needs to be made, the furnace could require major repairs. In this case, it would be far more cost-effective to consider getting a new unit.

Don't Take Chances With Your Furnace

Regardless of the problem, you should always avoid taking chances with your furnace. Not only is it dangerous to try and repair the furnace on your own, but it could also result in additional damage to not only the unit, but your home as well. If you detect any strange noises or odors coming from the furnace, it's essential to shut it off and call a professional.

The best way to avoid having to deal with furnace issues in the first place is to have it inspected and serviced regularly by a qualified technician. In addition to keeping your furnace running smoothly, regular maintenance will also improve its efficiency and help you save money in the long run.
