AC Maintenance: Air Conditioning Maintenance Tricks You Can Do Yourself

Not many chores tend to pay off as much as cleaning your air conditioning unit does. Did you know that a dirty or a clogged air filter can increase your air conditioner’s energy consumption by up to 15%, according to

Imagine how much money you might be wasting by not cleaning your AC regularly! A properly maintained AC unit will not only cost you less but operate better and be safer for both you and the environment. It will also last much longer before you need to replace it.

However, while you can do most of these tasks independently, there are still some tasks best left to a professional with proper license and training. Learn more about the importance of choosing a reputable HVAC contractor here:

In this article, we will give you a few useful maintenance tricks most homeowners can tackle on their own. However, if you feel uncomfortable or insecure in your skills at any time, don’t hesitate to reach out to a professional. Always mind the safety precautions and always cut the power supply to the unit before doing anything else.

Cleaning and Replacing Air Filters

Cleaning the air filters and replacing them when they’ve served their purpose are the two primary AC maintenance tips. You should do this every month during summer and winter when the AC is used the most and at least once every three months during spring and fall.

The filter is usually located behind the return air grille on the walls or ceilings, inside the blower, or on the unit’s side. As the filter collects dirt, dust, and allergens, the airflow to your home is cut, and your air becomes contaminated with dangerous particles.

Inspecting the Components and Wiring

As we mentioned, always cut the power to the air conditioner before you start doing anything. This is particularly the case for this part of the maintenance process. After you’ve cut the power, remove the access panel from the condenser unit, and look for signs of overheating.

This usually includes melted isolation and burnt wires. While you’re at it, make sure all the connections are tight with an electrical test meter if you have one. Look at the contactor switch and consider replacing it if necessary. If you find any of these issues but don’t feel safe replacing the wires or other components, call in a professional service that offers air conditioning repair in Oklahoma City or repair services wherever you are based.

Consider Replacing the Thermostat

One of the most important components of the air conditioning system is the thermostat. It ensures your AC works properly and keeps your home at the desired temperature. However, if your thermostat is an older, mechanical model, perhaps you should consider switching to a programmable one and replace your A/C unit.

A programmable thermostat lets you set the temperature to your liking. You can even program the AC o turn it on at a precise time, for example, just before you return home from work. A programmable thermostat can also help you save a lot of money, as the Blast Auxiliary AC unit won’t waste precious energy while no one is at home.

Check the Condenser Unit Fan

Check the fan on the outdoor condenser unit’s top to ensure nothing prevents it from operating properly. If the blades become damaged, chipped, or cracked, replace the fan with a new one. With older AC units, these fans also have to be regularly oiled.

Clean the Outdoor Unit

As time passes, dirt, grass, dust, and other debris tend to pile up on the outdoor unit. This may result in the system operating at a reduced capacity and with limited airflow. To clean the outside unit, gently wash all the debris with a garden hose.

Never use a power washer, as it can bend or damage the fragile fins on the coil. Also, make sure you trim any shrubs or plants around the unit to keep the airflow unrestricted.
