The quality of the air in your home is dependent on how well you keep up your HVAC system. Many people don't realize how important the furnace is when it comes to the cleanliness of the air inside their home. They think that the furnace is really only responsible for producing hot air and pumping it into their rooms. In reality, the furnace is also responsible for filtering the air and removing bad, allergen-filled air from your home. Basically, if your furnace is not properly maintained, the quality of air in your home is going to be significantly reduced.
This can lead to odors, dustiness, and (worst of all) allergens and mold buildup. Basically, it pays to have your furnace system regularly serviced. This article explains what you need to do in order to keep your furnace working as effectively as possible, particularly when it comes to their cleanliness. Some of these jobs will require some DIY maintenance, and some need to be done professionally.
Changing the Filter
First of all, you need to make sure that you change your filter in a timely manner. That is, filters have limited lifespans, ranging anywhere from 3 to 12 months. The lifespan of any filter depends on the furnace model, the size of your home, how often you run your furnace, and many other things. Basically, there are no set rules for how often you should change your filter, so it is best to actually inspect your filter and replace it if it is dirty.
Filters can get dirty, and will often only last a fraction of their lifespan, especially during times that you are running your furnace for extended hours. Most filters are very easy to find and replace. You don't need any tools for extra products to switch out a filter. But this is an easy job you can do yourself.
There are many more complicated jobs that to need to be handled by pros. Specifically, you should have your furnace cabinet professionally cleaned by HVAC technicians. They can check your furnace fuel levels, clean your air ducts, and help maintain your entire system. Calling in a pro at least once a year is necessary.
Some regular professional maintenance can go along way in preventing more long term, serious, and ultimately expensive damage to your system. But, you will obviously still need to call in pros every once in a while.
