1. Remove the Cover and Clean Your Outside Condenser
We’ll start with the outside condenser unit. Once you make sure it’s turned off, remove the cover and pull any dead grass, leaves or branches away from it.
You can then clean it with a soft brush or water. But be careful: the condenser fins can bend easily, and won’t work properly if damaged.
Once cleaned, it’s a good idea to do a visual inspection of your outdoor unit for any damage. If you find some, don’t turn your air conditioner on until you’ve had it checked by a professional.
2. Check Your Refrigerant Line
There are 2 refrigerant lines leading from your condenser unit into your home. The larger suction line is wrapped in insulation.
This insulation helps make sure the air stays cool: without it, your air conditioner won’t work at maximum efficiency, wasting your money. So look for any cracked or worn spots. If the insulation isn’t up to snuff, have it replaced.
