Even though we're getting out of the warm summer months and moving into wintertime, it's still a good idea to make sure you do your regular air conditioning maintenance to ensure that your unit will work properly again when it's time to turn it back on. Though you may think that these are jobs best left to a professional, most of the items on this list can be done by the homeowner. If you're unsure about or uncomfortable with performing any of these tasks, however, be sure to contact a local technician that can take care of the issue for you.
Change Air Filters Regularly
Most experts agree that air filters inside your home should be replaced every few months, depending on usage. Though there is normally only one air filter, some homes have two or even three that need to be replaced regularly. Failure to do so can cause gunk and grime to build up on the inside your air ducts and on your air conditioning unit itself, which will make it work harder, causing premature failure and higher utility bills in the process. It's one of the easiest forms of AC maintenance you can do, but it's also one of the most important.
Clear the Debris
Walk outside and inspect your air conditioning unit. If there are grass and tree limbs up against your AC unit, be sure to clear those away as they can restrict airflow to the unit. If it's a recurring problem, make sure that you cut nearby trees or install a barrier of some kind to prevent the issue from happening in the future. Regular visual inspections while doing other activities will also help to alleviate this issue.
Clean the Guts
After you've ensured that the debris is clear from the outside of your AC unit, switch off the power to the unit temporarily and take off the metal caging. Take a broom or a can of compressed air and blow out the gunk that is inside the AC unit, comprising mostly of grass, leaves, and cobwebs. This will allow the unit to breathe more freely, which reduces wear and tear on your machine.
Empty the Drain
Your condensate drain is where all the excess water drops that comes from your AC unit. Though it should drain naturally out of a pipe that leads away from the drain, sometimes it can be clogged and cause a buildup in the pan that leads to spillage. This will eventually create water damage if left unattended, so make sure the drip pan is empty before you shut it down for the winter.
