Sometimes, during summer, the scorching heat can be unbearable. To ensure you stay cool and comfortable, you need to rely on your air conditioner to do its job, especially during these peak temperatures. But how would you know if your AC unit is operating efficiently? You should get your air conditioner checked and tuned up regularly to keep it in good condition.

This article discusses a few things that you can expect during an AC tune-up.

Testing Performance

Performance testing is an integral part of an AC tune-up. This process involves a series of systematic checks and measurements to ensure that the AC system functions at optimal levels, providing maximum efficiency and comfort. The primary goal of performance testing is to identify any potential issues that may hinder the system's functionality or lead to unnecessary energy consumption.

A key aspect of performance testing focuses on the cooling function of the AC system. This is typically measured by comparing the temperature of the air entering the AC unit with the temperature of the cooled air it produces.

If the difference between these temperatures, also known as the 'temperature differential,' is not within the standard range, it could indicate problems such as low refrigerant levels, a malfunctioning compressor, or a dirty evaporator coil. These issues can significantly reduce the system's cooling capacity, leading to inadequate cooling and increased energy use.

Another critical part of performance testing during an AC tune-up is assessing the system's airflow. Proper airflow is essential for the efficient operation of an AC system.

Technicians measure this using anemometers or similar devices, which can detect any decreases in airflow that might suggest obstructions or leaks in the ductwork. Furthermore, they inspect the air filters, as clogged or dirty filters can restrict airflow, force the system to take longer to cool the space, and use more energy.

Lubricating Moving Parts 

Another important part of an AC tune-up is lubricating the system's moving parts. This step helps prevent excessive friction and wear in the motor and its components, as well as reduce the risk of overheating. It also promotes the smoother operation of the AC unit.

Before adding lubricant to the system, technicians typically examine all of the moving parts for signs of wear or damage. They then clean and lubricate any necessary components, such as the fan blades, motor bearings, fan motor shafts, and blower wheels.

Technicians may also inspect and replace the fan belt, which can become worn over time. A damaged or loose fan belt can cause a decrease in airflow and create loud noises during operation. For more information on AC tune-ups, contact a professional near you.
