  1. Replace your air filters: This is one of the most important ways to maintain your air conditioning unit, but it’s also one of the easiest and cheapest. If they’re not changed often enough, a dirty filter can place unnecessary strain on your air conditioning unit. They should be cleaned monthly and changed once every three to nine months. Check your owner’s manual for specific recommendations on your unit.
  2. Clean ducts and vents: An air duct cleaning, as well as a vent cleaning, can increase efficiency, improve the lifespan of your air conditioning unit, and give you cleaner air to breathe at home.
  3. Clean your air conditioner coils: The evaporator coil and the condenser coil will collect dirt over months and years, which can reduce airflow and insulate the coil — ultimately reducing its power to absorb heat. You’ll need to check your coils every year and clean as needed, removing dust, buildup, and particularly foliage to keep things operating smoothly.
  4. Prevent debris in your unit: Even better than cleaning debris from your unit is keeping it from ending up there in the first place. It’s a good idea to trim the foliage back two feet away from your air conditioner unit to ensure you’ll have adequate air flow.
  5. Comb coil fins: Evaporator and condenser fins are made of aluminum and can be easily bent. This can result in blocked airflow and should be fixed. It’s easy to take care of this task with a fin comb, sold by air conditioning wholesalers, which can comb the fins back into position.
  6. Inspect the condensate drain: Take a look at your condensate drain at the start of each season. You should check to make sure the drain isn’t plugged up, as this can cause water damage and increase indoor humidity levels.
  7. Inspect refrigerant lines: Ensure that refrigerant lines are intact. If there is any damage or insulation is missing, be sure to replace them immediately.
  8. Inspect the fan motor and blades: Look for wear and damage on the fan motor and blades. You should also lubricate these parts as necessary.
  9. Check the air conditioner refrigerant level: Take a look at how much refrigerant your air conditioner has. Ensure that it isn’t too high or too low, as either will make your system less efficient and can damage the equipment. This maintenance typically requires the help of a professional.
  10. Clean your air conditioner condenser unit: Each year, you should clean your air conditioner condenser unit. This can be done in about an hour and is easy for anyone to take care of.
