Five Tips from the Pros to Maintaining Your AC Unit

Posted on AC Maintenance, AC Tips, Tips January 10, 2019

Nobody wants to deal with their AC breaking down, and you don’t need to! Follow these tips for air conditioner preventative maintenance service.

Want to make sure your AC unit is running at its optimum level? Look into air conditioner preventative maintenance service.

Why is this important? For starters, AC units tend to break down if they aren’t serviced on a regular basis. Plus, a well-maintained system will last longer before you have to replace it.

Not sure where to start? Here’s an air conditioner maintenance checklist that should help you keep your unit in tip-top shape.

  1. Replace the Air Filter

As a general rule, you should replace your air filter once per month — at least during high-use seasons. If you have a reusable filter, you can just clean it and put it back. It’s usually located in the return air duct or the blower compartment.

Why bother replacing your air filter so often? Well, a dirty filter reduces airflow in your AC unit, causing it to work harder than normal. This will also lead to the air itself becoming dusty, potentially triggering asthma and allergy symptoms.

  1. Inspect the Wiring

If your air conditioner is acting sluggish, you’ll want to peek inside it. Turn off the power to the system and remove the access panel on the condensing unit. If the wires seem burned or blackened, the system is overheating.

If the wiring appears fine, the issue may lie with the contactor switch. Take a look at it — does it display excessive pitting? If it does, you may need to replace it.

  1. Set Your Thermostat Correctly

While optimizing your thermostat’s settings, keep the outdoor temperatures in mind. If the difference between the indoor and outdoor temperature is too great, your AC unit will consume too much energy.

In most cases, you should set your thermostat to 78 degrees while you’re home. When you’re leaving, consider turning it up a few degrees.

  1. Examine the Condenser Fan

Again, you’ll want to start by turning off the power to the unit. Then, make sure that the fan at the top of your outside unit is in good condition. You may notice cracks on one or more of the blades, which is a sign you should replace them.

Of course, some older air conditioner units need extra maintenance. In this case, that includes oiling the fan motor bearings from time to time.

  1. Clean the Outside Unit

Finally, you’ll want to examine your outside unit for dirt, leaves, grass clippings, and so on. If you find some debris, wash it out with a garden hose. Don’t use a power washer, and watch out not to damage the fins on the coil.

Also, keep in mind that landscaping is a factor in your AC unit working properly. For example, you shouldn’t plant any shrubs within 3 feet of the unit. Other than impeding the airflow to the unit, they can create lots of debris on their own.
