Get your AC ready for summer!

Air conditioners are the most crucial part of the home or business during the summer months. It is imperative to get ready for the coming summer temperatures. In this article I will go over a few things to look at on your Air Conditioner to get your AC ready for summer.

Capacitors are one of the most common things that go bad during the summer temperatures. You can prevent this by testing the capacitor Microfarad level by using a multimeter that is equipped with the feature. I recommend testing the indoor fan capacitor and outdoor fan capacitor. You can test the capacitor by removing one side of the circuit on the capacitor. Put the test leads of the multimeter across the top prongs of the capacitor. It should give you a microfarad reading of what the capacitor is rated for. So for example if you have a 12.5 microfarad capacitor. It would be most likely rated for plus or minus 6%.

12.5 x .06 = .75 So the capacitor shouldn’t be lower then 11.75 microfarads. Let’s say you have a capacitor that tested 11.13 microfarads. Then you would want to replace the capacitor with one that is within the range.

Most home AC’s use Dual run capacitors. These are two capacitors that are built in one. One is used to run the Compressor, and the other is used to run the outdoor fan motor. Capacitors are used in a electrical circuit to boost the amperage. So they can hold a charge when removed from the circuit. It is important to discharge the capacitor by putting a piece of metal between the sets of prongs on the top of the capacitor. I like to use a screwdriver.

Fan motors should be working without any excessive vibrations or bearing sounds. It is important to be careful of bending fan blades.  It is hard to repair a fan blade when a fan blade gets damaged. It is easier to just replace the fan blade with the exact same model of blade.

Condenser coils get dirty over the years with dust and other things. You can spray off the coils with a garden hose to help remove the dirt. I recommend using a condenser coil cleaner if the coils are really dirty. Most common spray on cleaners will require water for the condenser coils and no water required for the evaporator coils. Since there is a build of condensation on the evap coils during operation that will rinse the chemical cleaners off.

Most drains will get clogged over time with dirt, animal hair, and a sludge build up. I recommend checking the drains coming off the evap coils. You should clear the piping with water or compressed nitrogen if there is a clog. I like to use the drain dawg kit that has a long hose attached to a nitrogen regulator and tank.
