2 Central AC Maintenance Tasks Only A Professional Should Perform

To keep your home's central air conditioning system running smoothly and efficiently, there are certain things that must be done to maintain it. There are a few things that you can do yourself, such as changing the filter and making sure the exterior unit is clean and free from debris.

However, there are some things that you should not attempt yourself that could damage the system. Instead, you should rely on a professional to perform certain central A/C system maintenance tasks, such as those discussed below.

1. Making Sure the Condenser Coils Are Clean and Free from Damage and Debris

One maintenance task that should be handled by a professional during a regular maintenance service call is making sure that the condenser coils are in good condition. Since the heat and cold air exchange happens through these coils, they must be kept clean from dirt and debris and need to be checked for any damage such as dents or scratches.

When the technician checks the coils, they will check for these signs of damage, and if any are found, the technician can replace the affected coils. They will also remove any dirt and grime carefully to help with air exchange without the risk of causing damage to the coils.

2. Checking and Lubricating All Moving Parts and Bearings in the System

Another task that is performed during professional maintenance on your home's A/C system is making sure that all moving parts and bearings are damage-free and well-lubricated. Within the motor and fan, the bearings keep things moving smoothly as long as their surfaces are not ground down or too dry.

When the maintenance technician performs maintenance on the air conditioner, they will first check to see if the bearings, belt, and motor spindles need to be replaced. If not, they will ensure they are well-lubricated so that friction and heat caused by constant motion does not wear them down prematurely.

While there are some things you can do yourself to maintain your home's central A/C system like change the filter and clean the outsides of the exterior unit, there are some things that are best left to a service technician. When they make a maintenance call, they will perform such tasks as cleaning and checking the condenser coils and lubricating the bearings and other moving parts of the system.
