Your condenser unit may appear intimidating, but keeping this component clean and running efficiently is pretty straight forward.


Power off the unit. The safest and most responsible way to perform AC maintenance on your unit is to power it off before you begin. By cutting off the power supply, you can ensure a deep clean and limit the risk of injury.


Clear debris. The less that could potentially enter and clog the unit the better. Removing the cap and taking a shop vac to the inside of the condenser is a great way to clear all the leaves, tree branches, gravel, and gunk that may be building up in your unit.


Clean the fins. The fins are the small metal prongs that protect the condenser coil. Many homeowners experience clogged fins on their air conditioners. You can use a hose (on a low setting) to remove any unwanted buildup on the outside of your fins. If possible, it’s best to remove the lid of the condenser and spray from the inside out.


Fix the fins. These delicate metal pieces are prone to being bent. To ensure they are working properly, you can use a butter knife and (carefully) straighten the fins on the condenser unit. You could also buy a fin comb, which is a small tool that will drag and straighten many fins at one time.


Check insulation on coolant pipes. The line that transfers the refrigerant through your air conditioning system should be covered by a layer of thick insulation. Sometimes sun exposure can destroy these protective linings. Check on this insulation regularly, as it keeps the refrigerant cold and protects anything from happening to the pipe.


Clear the drain. Your AC condensate drain fills with — you guessed it — condensation and water that your air conditioner releases. The plastic tube can be heaven for mold which could clog your system and really back everything up. Use special AC pan pills to keep your condensate drain from clogging or use a shop vac to remove a clog if it’s already formed.
Check your filter. A quality filter is essential for keeping dirt and grime out of your blower. Typically, we recommend that every home change their filter every three months or so. This allows your AC to work efficiently and avoid performance issues.
Check for leaks. Unfortunately, not every AC maintenance service can be performed at home. If you detect a leak in any of the refrigerant lines in your AC unit, you need to employ the help of a professional.
