There are several types of heating sources that you can choose from, such as gas or electric furnaces, fireplaces, or wood stoves. It's important to learn how to troubleshoot your heating source in case anything happens and you need to restore the heat before the home gets too cold. Many people who live in residential properties have a furnace. Typical furnaces can last over a decade when kept on a good maintenance schedule. There are some issues that can spring up over time due to simple wear and tear over the years. This article explains what problems you may see and what is causing it.

Strange Noises

All furnaces will make a noise while it is running but there are some noises that it shouldn't make.

Rattling

Rattling noises in the heating system in the property means something is not right. When it comes from the furnace itself, it might be that the motor is no longer balanced correctly. It can also be a loose screw, damaged vents, or loose metal. If it is any of the last three, you can repair the damage and it should fix the problem. The motor issue would need to be repaired by an HVAC professional.

Squealing

A squealing noise indicates a problem with the belt for the appliance. It has most likely become loose or has slipped off completely. The belts are rubber and can wear thin over time so it is a fairly common issue. Luckily, if the belt is not damaged and just loose, you can slip it back into place. A damaged belt needs to be replaced altogether.

Insufficient Heat

A home that is not heating properly can be an issue with a few things.

Damaged Vents

The vents carry hot air from the furnace to the rest of the property. Any holes in the vents will allow cold air to mingle with the hot air. The result is cool air coming out of the vents instead of heat. You should have an HVAC contractor check the ventilation system each year to make sure it is not damaged when the cold season starts.

Filter

A quick solution for insufficient heat is a dirty air filter. You need to replace the filter at least every six months. Check your user's manual to find the correct type of replacement because they are all different and not universally compatible.

Conclusion

If your furnace is acting up, schedule an appointment with a residential heating repair contractor so they can diagnose the issue. You may need a repair or even a replacement depending on how severe it is.
