There are so many things that can go wrong with your heater. That is why it is important to understand what are some of the most common heater issues, so if they ever come up for you, you will know how to address them.
Clogged Air Filter
If filters on your furnace get dirty, your furnace is not going to be able to properly circulate air throughout the system. That is why it is so important to check the condition of your filters every few months.
Your filters may require more frequent check-ins depending on your circumstances. For example, if you have pets in your home, their fur and dander can clog your filter up faster. Or if you smoke in your home, that can also clog your filters up faster.
A clogged filter is not just a nuisance, it can have a serious impact on how your system operates, which is why you are going to want to get it fixed.
Your thermostat is what provides your furnace with the information it needs in order to operate properly and keep you warm. If your thermostat isn't working properly and the battery isn't dead, you are going to need to replace it. You are going to want to bring in a furnace repair service to change your thermostat and install a new one. When you install a new thermostat, be sure to upgrade to a smart thermostat, which will provide you with great control over how you heat your home, and should help you save some money along the way as well.
Blower Running Without Turning Off
Your blower should not be running all the time. It should turn on and off. If your blower is running all the time and it never seems to take a break, you are going to want to get a professional to inspect your unit. More than likely, you have a broken limit switch or a faulty limit switch. You want to get this issue fixed and addressed as soon as possible, as a broken limit switch can put additional stress on your unit, and lead to other related issues.
Your system should only make so much noise when it is operating. If it is making a lot of noise when it is operating, you are going to want to get it inspected. Sudden, excessive noise generally means that you have some sort of mechanical problem with your unit. Something inside the furnace is loose or broken that shouldn't be, and that is what is creating the issue. The sooner you get the issue addressed, the less serious the damage may be to repair. The longer you let the issue go on, the more serious the issue may be to address.
If you experience any of the above issues with your furnace, address them right away. If you are unsure how to address an issue, call in a professional heater repair service to work with you to ensure you have the heat you need to be comfortable.
