Many people like to spring clean their homes once the weather warms up. If you have already made out your list of things to do you may not have thought about your HVAC unit. Getting it maintained in the spring, however, will help the HVAC unit to last much longer. Below is some more information about this so you can get started.
Change the Filters
It is important that you change the filter on your HVAC unit regularly. If you do not, dust, debris, etc., will build up on the filter and restrict air flow. Your home will then not stay as warm or cool. There are many types of filters on the market. The standard fiberglass filter is commonly used but these filters do not last as long. Depending on how often you use your HVAC unit, they may only last approximately a month. Instead of this, purchase a HEPA filter, as it can last approximately six months and you can clean the filter using a vacuum nozzle.
Go outside and look around the HVAC unit. It should be clear of debris, such as leaves, sticks, and grass. If these things build up against it, the fan will be blocked, which will restrict air flow into your home. In some cases, debris can build up inside the cabinet also. Remove the cover and inspect it. If you see a lot of debris, remove it by hand or use a vacuum.
Check the Fan Blades
While you have the cover off, check the fan blades to ensure they are not damaged in any way. Hail can easily bend these blades because they are so thin. If you see that they are bent, you can purchase a fin comb at a home improvement store that is made specifically for this purpose. The fin comb will come with complete instructions on how to use it. If you cannot get the blades straightened out, contact an HVAC contractor to replace the fan for you.
Check Duct Work
The duct work in your home can develop leaks over time. If this happens, your HVAC unit will have to run longer to keep your home heated or cooled. You can check for leaks on your own. First, turn off the HVAC unit and find the air ducts, which are generally found in crawl spaces or attics. Run your hand along the ducts to see if you feel any air coming out of them. You may also see black marks on the duct work, which is a sign that you have a leak. In most cases, you will find leaks where the ducts make a connection to registers and vents. If you find leaks, you can seal them up with mastic type sealant that can be purchased at home improvement stores.
If you notice your home does not stay heated or cooled, contact a heating repair or HVAC contractor to repair it for you.
