Top 5 Air Conditioner Maintenance Tips Everyone Needs to Know

Posted on HVAC careers, Tips, Uncategorized October 15, 2018

Imagine relaxing in your recliner on a hot summer day with an iced tea in your hand. All of a sudden, this dreamy day comes to an abrupt halt when your AC decides to turn off – you’re already sweating, right?

After checking out the problem, you discover it was because you didn’t clean it out or change the filter.

By doing routine maintenance on your unit, you can avoid ac troubles and repairs. If you’re not sure what this entails, no worries. Here are 5 air conditioner maintenance tips that you can incorporate in your normal cleaning routine.

1. Clean and Replace the Air Filter

Replacing your filter, or cleaning it if you have a reusable filter, is one of the most important aspects of air conditioning maintenance. It should be done once a month during high usage seasons, and once a season during the low use ones.

When the filter is filled with allergen particles, dust, and dirt the air flow will reduce and make your unit work harder.

2. Fix Leaks

Ducts can lose 30 percent of airflow through leaks, and window AC units can be really tough to seal properly. For window units, you can grab an incense and hold it where the window and frame meet. In the case of a central AC hold it near the duct connections.

If the smoke blows around then you have a leakage on your hands. For window ACs, you can stuff foam around the window frame. To fix ductwork, use foil tape to seal it.

3. Check Wiring

Before you check the wiring make sure you turn off all power to the unit. After that, remove the access panel and check for overheating, melted wires, or blackened and burned wires.

Check any electrical connections to make sure they are nice and tight and replace the contactor switch if you see excessive pitting.

4. Keep an Eye on the Thermostat

Keep an eye on the thermostat and make sure that it’s keeping your house at the right temperature. If you have an old thermostat than you’ll need to keep a better eye on your set temperature as the outside temperature fluctuates and adjust if you think it may be overworking or vis versa.

A programmable thermostat, such as the NEST thermostat, will allow you to set the temperature to a certain point while nobody is home, usually with a smartphone app. You can even work it so it will start cooling the house down again before you come home.

5. Clean the Outside Unit

Like with most things, time is a cruel mistress. Over time, leaves, dirt, and grass will build up in your outdoor unit and cause it to have to work a lot harder to cool you off. Before you even start this process, turn the power off to the unit.

Use a garden hose to clean out the debris from the unit. Do not use a power washer and take extra care not to bend or break any of the fragile bits. For a deeper clean, you can always hire a company to help you out.

Air Conditioner Maintenance Tips that will Keep it Working Longer

Performing all of these air conditioner maintenance tips will prevent your unit from turning off on you during the summer. Make sure the filter is cleaned out, keep an eye on the thermostat, check the wiring, and clean your outside unit. Keep relaxing your summer away with cool air.
