Air Conditioner Parts That Must Be On A Maintenance Checklist

An air conditioner is an essential accessory for a home or workplace. To prevent your AC from breaking down requires regular maintenance by a professional technician. You have to understand the important AC parts that should not miss on the maintenance checklist. Keeping these in good condition will keep your unit working effectively and efficiently.

Air Conditioner Parts That Must Be On A Maintenance Checklist

The thermostat controls the AC and tells it what to do. Have you noticed your air conditioner turning on and off? Perhaps the thermostat isn’t not going to the appropriate temperature. This is a sign that there’s a problem with the thermostat. Old dial-type thermostats are problems such as poor calibration giving the unit inappropriate instructions.
During scheduled maintenance, the technician will fix the problem on your thermostat by replacing or recalibrating it. If you have a modern thermostat that appears to be a bit tricky to program, you have to check the instructions in the user manual. Alternatively, you can call a technician to come and make sure that the thermostat settings are correct.
Condenser coils
The condenser coils are an essential part of an outdoor unit of an air conditioner. These eliminate heat from the air by expelling it outside. However, these coils don’t work effectively when covered in dirt and grime due to poor maintenance. Dirty coils can’t transfer heat effectively and your unit will have to work harder. This leads to increase wear on the various parts and eventual unit failure. Scheduled Houston air conditioner repair must involve inspecting these coils to avoid freezing because of airflow problems.

Evaporator coils

These are filled refrigerant and are absorb heat from the air by working as a sponge. The evaporator coils need warm circulating air to work properly. Ice buildup on the outside makes the coils become too cold leading to poor airflow. Afterward, you’re likely to get warm air or nothing from the air conditioning unit. To restore appropriate air quality in your environment requires the evaporator coils to be regularly during the scheduled maintenance procedure.


The ductwork runs throughout the walls and ceilings carrying cooled air from the AC to all areas of the house. Unfortunately, poor maintenance and rodents might cause holes or breaks in your ducks. This causes the expensively cooled air to end up inside the walls where‘s not required. Additionally, this situation is likely to make your unit work harder and you can’t escape a hefty energy bill. Inspection and appropriate repairs during scheduled maintenance are helpful to ensure that your ductwork is always in good shape.


This is for blowing indoor air over the evaporator coils to have it cooled. Another fan blows the air over the condenser on the outdoor unit expelling absorbed heat from your home. In case these fans aren’t working properly, you’re likely to end up with AC problems and low-quality airflow. These fans are likely to get problems from lack of lubrication, faulty motor, dirt and debris buildup, and worn belts. Failure to get immediate professional assistance puts your unit at risk of compressor failure and eventual failure. Regular maintenance is the solution to ensure that the fans are working efficiently and effectively.

Expansion valve

This lies between the hot and cold parts of the AC . The expansion valve regulates compressed liquid refrigerant that moves into the evaporator. It should be kept free from dirt and grime to ensure that it opens and closes effectively. During scheduled maintenance, the technician will inspect the expansion valve and make appropriate steps to keep it in good working condition. 


Air conditioners come with inbuilt filters that breathe clean air in your home . Additionally, the filters eliminate dust particles that you can’t see with the naked eye. With time, the particles are likely to build upon the filters making them not to work efficiently. This explains the filters should come on top of your maintenance checklist. The technician will clean or replace the filters to guarantee fresh and clean air in your space.

Bottom line

An air conditioner is handy to make your space more comfortable. However, it’s prone to dirt and grime buildup over time. Scheduled maintenance and repair are essential to ensure that all essential parts highlighted above are always in good working condition. This will keep your unit working efficiently for years.
