While you will need an HVAC technician to complete HVAC maintenance tasks that include checking the system and refilling refrigerant, there are some other tasks you can DIY. These tasks are not quite as technical, nor do you need an HVAC license to complete them. They are safe enough to do that you can do them as often as you like, and they contribute to the better and more efficient operation of your air conditioning unit.
Clearing Weeds, Vines, and Overgrowth
The outdoor part of your unit needs to remain free and clear of vegetation. This means that you cannot have any vines, weeds, or other plants growing up around it or wrapping around and through it either. Spend some time every other week in the warmer months of the year clearing vegetation from around the unit to make sure the internal components are not choked off and can funnel hot air outdoors.
Washing and Dusting the Outdoor Unit
Dirt and debris gather on outside units very quickly. On the same day you clear vegetation, carefully wash the unit with a damp, soapy cloth. Let it air dry. Use a duster to clean and clear the fan openings of dust. Just make sure your unit is not running when you do any of these tasks or you could cause more problems than you need.
Changing the Fuses
Most central air conditioning units have an outdoor fuse box. Follow the directions on the box to remove the fuse holder. Take the cylindrical fuses to a hardware store and have them tested. If there are no signs of corrosion, and the fuses test positive for energy, reinstall the fuses and the fuse box. If there are signs of corrosion, or if either of the fuses are dead, replace both fuses to make sure the new fuse does not cause the old fuse to blow.
Changing Your Furnace Filter
Furnace filters play a big role in the performance of your heating and cooling units. If you buy the cheapest furnace filters, you will have to replace them more often. Usually three weeks to a month is standard for the cheapest filters. You can invest a little extra money in two, three, and four month filters, which you do not have to change quite as often. The more expensive filters also reduce significant allergen counts for both indoor and outdoor allergens, cleaning your air while your heating and cooling appliances do their thing.
