Air Conditioner Maintenance Checklist: A HomeOwner’s Guide

Last Updated on March 14, 2022 by Kravelv

Most HVAC system issues are caused by improper maintenance. When you make sure that your air conditioner is serviced on a regular basis, the unit will stay in great condition. Air conditioner repairs can be expensive. Fortunately, there are several things you can do to prevent expensive air conditioning repairs.

Inspect the Power Cord and Connections

The cord that connects the power source to the air conditioner can deteriorate. If the cord has an electrical shortage, you should replace the cord immediately. You should also tighten all of the power connections.

Clean the Filters

Remove the air filters and wash off the dirt. Spray the filters with an antiseptic cleaner. After you spray the filters, you should wash both sides in warm water. Remove any debris that is lodged in the filters. You should replace the filters every three months. If you have dogs or cats, you should change the filters every month. You should also purchase a high-quality filter. A high-quality filter will absorb tiny particles.

A Ductless System and the Heat Exchanger Coil

If your air conditioner is a ductless system, you will have a clear view of the heat exchanger coil. The coil is behind the filters. Ensure that the coil is not covered in hair or dirt. If the coil is dirty, you can clean it with a vacuum.

Inspect the Outdoor Unit

Before you inspect and clean the outdoor unit, you should remove all obstructions from the area. When you remove all of the weeds and decomposing leaves, you can make sure that air is flowing through the system. If air is not flowing, the fan motor might be broken. A blocked coil can also limit the airflow. If your air conditioner is not pushing out a reasonable amount of air, you might need to hire a professional HVAC technician.

Check the Refrigerant and the Heating and Cooling Modes

You should make sure that the air conditioner has an adequate amount of refrigerant. If the unit does not have enough refrigerant, the air conditioner will consume more power. If your air conditioning unit does not switch between hot and cold, there could be an issue with the reversing valve.

Check for Signs of Corrosion or Rust

If your air conditioning unit is showing signs of corrosion, you should fix the problem immediately. A small amount of rust can be painted. If the unit has a large amount of rust, a professional technician will have to remove the rust.


Heating System

You should check the oil and gas connections. You will need to check the gas pressure and the heat exchanger. A cracked burner will operate less efficiently, and it is a fire hazard.

You should clean your air conditioner at least twice a year, and you should hire a professional if the air conditioner has any mechanical issues. A broken air conditioner can affect your health. If you have allergies or other respiratory problems, the problems could be caused by your air conditioning unit. You can keep your air conditioning unit at an optimal level by performing a pre-season check-up. HVAC contractors are usually busy during the winter and summer months, so you should inspect your air conditioning unit during the fall and spring.
