4 Common Garage Heater Problems and How to Address Them

Garage heaters require maintenance and cleaning to ensure they last long and work at their best at all times. This, of course, applies to most, if not all, things in the world, and just like anything else, the lack of maintenance and cleaning quickly leads to a broken machine or equipment that is expensive to fix.

That said, it pays to know the common problems garage heaters run into to help you quickly identify the issue and get it fixed before it is too late. As such, we want to share with you the common garage heater problems you may face, along with how to address them:

Problem 1. Casing Issues

The casing of a garage heater is the outer part you see or touch. It is a very important part of the equipment because it helps in the preservation of its functionality. If the casing is damaged and not properly fixed, it can form something called “arc”.

This is actually one of the common problems garage heaters have with their casings. If you notice the casing is damaged, it is best to get it fixed quickly. It is recommended to call a professional for help with this issue because it may need a quick repair to prevent the formation of further problems.

Problem 2. Overheating

Overheating is another common problem garage heaters have. If you leave it on for too long and the temperature inside the garage gets too high, then the unit will most likely burn up.

The best thing to do is set a timer or an automatic attendant to remind you when you should turn off the heater. This will help your heater last longer.

Problem 3. Foam Formation

Foam formation is a common problem faced by most garage heater users. It is caused by clogged ducts in your heater. If it is left unattended, the foam will continue to build up and become a huge problem.

Clogged ducts generally develop easily because of the kind of environment in which the garage heater is in. That said, you can prevent it by regularly cleaning your ducts. You should also check the unit and make sure all the parts are in good condition and are not broken.

Problem 4. Different Noises

This is another problem that can be easily fixed before it becomes a huge one through regular maintenance. However, if you have noticed a strange and loud noise coming from your garage heater, then you need to do something about it. It doesn’t matter if it’s a small, unusual noise or a huge one. 

As the cause of the noise can come from anywhere, the best way to fix them is to call up the professionals at Legacy Heating to identify what is causing the weird noises. That way, the problem can quickly be identified and fixed before the damage gets worse.

While these heaters come in many forms, they all do a good job of keeping your garage warm and cozy. The best way to take care of them is to look out for them and clean them regularly.
