There’s a common saying that goes, “It’s the little things that matter.” This could never be truer than with the furnace in your Pickering home. We all love the furnace that we have in our home but it is easy to forget about it. At Advantage Airtech, we respond to countless calls for heating service in the Pickering area. More often than not, there’s one small part of the furnace that many people forget about. It’s this small component, however, that causes the majority of heating problems in many homes. We thought that it would be helpful to our customers if we outlined some of the problems associated with this component and why it’s important to keep an eye on it.
The Air Filter
When you think of an air filter for your furnace, some people might think about air quality control. While those types of filters are a great way to improve the quality of air in your home, your furnace’s filter isn’t intended for that purpose. The filter in your furnace is there to keep large particles like dust and dirt from building up inside the unit. It filters the air returning from your home and the fresh outside air that both go into the furnace to get heated and circulated.
When the air filter gets clogged it can cause a number of major problems. Here are some of the most common problems.
- Low air flow – This one should be obvious. As the filter gets clogged, it restricts air going through your furnace. This will, in turn, restrict the air that is going to your home.
- Insufficient heat – Without proper air flow, your furnace won’t be able to provide the desired heat to your home. This can result in not enough heating in your home.
- No heat – In some cases, the filter can get so clogged that it won’t allow any heat or air to leave the furnace.
- Overheating – The heat exchanger inside your furnace is the piece of metal that the burners actually heat. The fan in your furnace blows air over the heat exchanger to heat it. But if there isn’t enough air flowing over the heat exchanger it can overheat and shut off.
- Heat exchanger cracks – When the heat exchanger gets overheated a lot it can actually crack.
- Reduced efficiency – As the air filter gets more clogged, it makes your furnace work harder to push air through your home. This greatly reduces the efficiency of the systems.
If you’re having any of these issues, it’s probably a good idea to check the air filter on your furnace. However, you never know what kind of damage has already been done to your system from a neglected air filter. It’s probably a good idea to have your furnace inspected by a professional to make sure that everything is okay.
