Step 1
Understand your central air conditioner. Know the components of your central air and how it works. Research your unit on-line or get a book that is for do-it-yourselfers (DIY). This will help you to maintain your unit.
-
Step 2
Shut the power off. It can be very dangerous to clean your unit if you leave the power on. Safety is valued above anything else when maintaining your central air conditioner.
-
Step 3
Clean the outdoor unit. Start by cleaning the condenser coil. You may also have to clean the fins. During the spring the fins may need to be cleaned once or twice a week. If your unit has oil on it, then reapply a little oil to the parts that need it. You can find the correct oil at any hardware store.
-
Step 4
Keep the outdoor unit free of any debris. The central air conditioner sucks air into the fins. Remove any shrubs or plants that are near your unit. This will keep your outdoor unit from sucking in leaves or dirt.
-
Step 5
Clean the indoor unit. Vacuum the bottom side of the fins with a soft brush, but only if you have access to it. Clear away any debris that is on or near the fan. Carefully remove the fan and take it outside. Spray it down with the water hose to clean it off. Place the fan back in the unit when you are done. Vacuum any dust that may be in the blower compartment.

Step 6
Change the air filter regularly to ensure that it will run properly. Change the filter once a month. Don't wait more than 2 months before changing the filter.
-
Step 7
Check sealing and insulating air ducts. Air can escape from sealing and insulating ducts that aren't airtight. Hire a professional to check your air ducts. This will keep your energy cost down and keep your central air conditioner working properly.

Step 8
Clear and clean the drain line. Attached to your indoor unit is a tube that drains off any condensation. Check the drain for any algae growth or blockage. If you see anything in the drain, then clean it with a simple half bleach and half water solution.
