Keeping your HVAC system in good repair is one of the primary keys to keeping up the efficiency levels. There's little point in spending thousands of dollars on a high efficiency furnace if you don't take steps to keep it at peak performance. In this article we'll discuss one of the major components of your furnace – the furnace blower. We'll fill you in on what the blower is, what it does, how to perform a few simple maintenance tasks and what to do when things go wrong. By the end of this article you'll have a short list of things you can do to keep your furnace functioning at optimal performance.
What is a furnace blower?
In forced-air HVAC systems air is first heated then blown, or forced through the duct work to the house. The blower is the part of the furnace that forces the air through the house after its reached the desired temperature. If it's not operational, your furnace isn't worth a whole lot. Of all the parts of a furnace, the blower is usually the portion that is working the most often and the hardest. Blowers are frequently the portion of the furnace that need to be replaced the most often, so don't be surprised if at some point, you need to purchase a new one or have your blower serviced.
Routine Maintenance of A Furnace Blower
You should be changing the air filter on your furnace on a regular basis. When you do, check to be sure that the blower is free of dirt, lint and dust. You can quickly clean the blower by using a damp rag or a vacuum cleaner. By keeping the blower clean and free of debris you will add life to the blower and keep it operating at a high efficiency rate.
Repairs and Replacement
Occasionally furnace blowers go out. When this happens – if it is the only thing wrong with the furnace – it is always less expensive to replace the blower than the whole system. Changing out the blower is not a difficult task, however it's important to note that some manufacturers require work to be done by a licensed HVAC installation professional in order to maintain the warranty. Check in your owners manual for details about your particular system. If you're looking to save a few dollars, call a local HVAC professional and ask them if they'll just do the installation if you purchase the part. Then you can shop around, find the best price on the replacement blower and still maintain your warranty.
Furnace blowers are a critical part of any HVAC system. Be sure to keep yours under good repair and call in a professional if something goes wrong to maintain your warranty. By keeping an eye on the state of the blower when you change your air filters you'll add life to the blower and reduce the chance of breakdowns and unexpected repairs.
