You are probably aware that any equipment in your home requires regular maintenance to keep running as long and as efficiently as possible. Among the long list of things you may make when it comes to maintenance, you must include your AC unit. However, you may not have too clear a picture as to what maintenance to the AC typically includes. If so, you may want to read more on the subject to understand the benefits of having an AC that is well-maintained.

AC Maintenance Checklist

Some of the tasks that an AC maintenance service may include are:

Checking the Filter

This ensures the efficiency and performance of your system. A dirty or clogged filter can reduce airflow, increase energy consumption, and damage the coils.

Cleaning the Evaporator and Condenser Coils

The coils are the parts of your system that transfer heat and cool the air. Over time, they can collect dirt, dust, and debris that can impair their function and cause overheating.

Checking the Refrigerant Level

The refrigerant is the fluid that circulates in your system and absorbs and releases heat. If your system is low on refrigerant, it can cause poor cooling, high energy bills, and damage to the compressor.

Inspecting the Electrical Components and Connections

These parts of your system control the power supply, thermostat, fan motor, compressor, and other functions. If they are loose, worn, or damaged, they can cause malfunctions, short circuits, or fire hazards.

Lubricating All Moving Parts

These parts of your system rotate or slide, such as the fan motor, blower motor, bearings, and belts. If they are not lubricated properly, they can cause friction, noise, or wear and tear. By lubricating them, you reduce friction and extend their life.

Cleaning the Drain Line and Pan

This is the part of your system that collects and drains the condensation from the evaporator coil. If it is clogged or cracked, it can cause water leaks, mold growth, or damage to your system or home.

Testing the Thermostat

The thermostat regulates the temperature settings and controls the on/off cycles of your system. If it is not working or calibrated properly, it can cause uneven cooling, frequent cycling, or high energy bills. Your technician will test your thermostat and adjust it if needed.

Testing the System Performance

A final step of an AC maintenance service ensures that it is working properly and efficiently. Your AC technician will test your system performance by measuring the airflow, temperature difference, voltage, amperage, and other parameters. They will also check for any unusual noises, vibrations, or odors.

An AC maintenance service is a worthwhile investment that can help you save money, improve your comfort, and extend the lifespan of your system. It is recommended to have an AC maintenance service at least once a year, preferably before the cooling season starts. Make a note to call an experienced AC technician once a year and keep your equipment running smoothly for years to come.
