How To Test Your AC System Before Summer

How To Test Your AC System Before Summer

With temperatures on the rise, we’re getting ready to welcome summer with open arms. That is, only if our air conditioners are working properly. We all know how miserable the middle of the summer can be without having a properly functioning air conditioning system to rely on and if you don’t dedicate a few hours to testing it now, you could be in for a rude awakening.

Does the sound of testing your own central air conditioning system scare the daylights out of you? Don’t let it. We’re not talking about complex inspections or making serious repairs on your own — a brief once over while checking a few key components will likely be all you need. Ready to get started? See the instructions below!

Step 1: Turning The System On

The very first thing you’ll want to do, if you haven’t done so already, is switch the thermostat from “heat” or “off” mode to “cool.” This will put your system into air conditioning mode and then by lowering the thermostat a few degrees below the current room temperature, the system should kick on.

Locate a nearby air vent and check to make sure cool air is blowing out. If not, you may have an issue on your hands, but it’s best to find this out now, before the sweltering heat settles in, right?

Step 2: Check The Airflow

Once the system is on, you should be able to feel the breeze coming through the vents. If airflow seems to be limited or completely restricted, check on the system’s air filter. A dirty or clogged filter could lead to limited airflow.

If you have a clean filter in place and airflow seems to be quite low, perform a visual inspection on all ductwork. A disconnected, crimped or otherwise damaged air duct could be another reason for inadequate airflow.

Step 3: Clean The Outdoor Unit

This is one of the most important components of your central air conditioning system and if it’s dirty, or the area around it is dirty, it could lead to a whole bunch of problems. Remove leaves, sticks and other debris from the unit (as long as the system is off), and clear brush and dirt from around the system.

Once again, airflow is extremely important and the outside component of the system is no exception.

Step 4: Read The Temperature

Locate an air vent as well as the return vent for the system. Tape a thermometer on the return vent and leave it there for roughly five minutes. Take a temperature reading and then tape the thermometer to an air duct or vent. Let the system run for about ten minutes and take another temperature reading.

The temperature of the air coming out of the vent or duct should be roughly 15° - 20° cooler. If it’s not, you could be low on refrigerant which will need to be replaced or charged right away.

Don’t get left out in the heat this summer. The best way to ensure your system is ready to take on warmer temperatures is to perform a quick test beforehand. If you determine that your system isn’t working properly, we’re here to help!
