Nearly 75% of American households have air conditioners. 

Air conditioners are a necessity during the summer, but what happens when they stop working? You don’t want to find out your air conditioner has a problem when it’s too late.

One way to save money is through preventative maintenance. By taking care of your air conditioner unit, you can keep your system running. With preventative maintenance, you’re also more likely to catch smaller problems before they become big issues.

Change the Filters

You should regularly clean or change your air conditioner’s filters. Some filters can be replaced, while others can be washed and reused. 

By regularly changing or replacing the air filters, you can reduce your AC’s energy use by 5-15%. When AC filters are dirty, the dust and dirt can obstruct airflow. This can reduce the efficiency of your air conditioner unit.

When the dirty filter blocks airflow, the air may instead bring dirt and dust into the evaporator coil. This can affect the heat-absorbing capacity of the evaporator coil.

How Often Do I Need to Change or Replace Filters?

How often do you need to clean or replace filters? During the hot summer months, you may need to replace them as often as every month or two when your air conditioner is in full use.

You may need to change them more often if there is a lot of dust in your environment, if you have pets with fur in your home, or if you use your AC unit a lot.

Adjust Your Thermostat

Another air conditioner maintenance tip is to adjust your thermostat and use a programmable thermostat. When you have the AC set all day, even when you’re not home, you’re paying to cool an empty house. 

With a programmable thermostat, you can set the times to raise the temperature of the house when you’re not home. You can also have the AC cool the house right before you get home. 

This way, you’re not wasting energy. You’re also extending the life of your air conditioner unit. 

Other Tips to Keep Home Cool

In addition to using a programmable thermostat, there are other ways you can lower cooling costs.

If you have ceiling fans, you should use them. Ceiling fans can keep you cool and allow you to raise the temperature of your air conditioner without sacrificing comfort. 

Another tip is to use curtains and drapes that are energy-efficient. They can help reduce the amount of heat that enters your home from the sun during the day. 

These are small ways you can keep your home cool and lower your energy use. 

Clear Debris from the Unit

Clear away any debris such as leaves, twigs, or weeds that are around your air conditioner unit. The debris and dirt could impede airflow and make your air conditioner work harder. 

If you have bushes, shrubs, or plants growing around your air conditioner, you can trim them to make sure they are not blocking the unit. 

Have a Professional Inspect the Unit

You should have a professional technician regularly inspect your air conditioning system. A professional can properly diagnose and repair issues with your air conditioner. 

You can schedule regular maintenance visits to make sure all parts of your air conditioner is running smoothly. A technician can also check your HVAC system and check for common problems

Signs You Need to Call an Air Conditioning Repair Service

Wondering if you need to contact an air conditioning repair service? Here are some signs that could indicate your air conditioner needs repair or servicing. 


If you notice leaking or liquid, you should call an air conditioning repair service to get that checked out right away. Leaking can lead to mold or structural damage in your home.

Weak or Warm Air

It’s in the middle of the hottest summer months, and you turn on the AC to get some relief. All you feel is weak or warm air coming out. 

If your AC is blowing warm or weak air, then this is something that needs to get checked out.

Unusual Sounds

Do you hear strange sounds coming from your AC unit when you turn it on? Unusual sounds could indicate a problem with your AC.

For example, from the outdoor AC unit, you may hear clicking or banging. This can mean something is obstructing the fan. 

If you hear any strange noises coming from your AC when you turn it on, you should have a technician inspect your system. 

Constant Repairs

Do you feel that you constantly have to repair your air conditioner unit? If your unit is older, it may be nearing the end of its life.
