AC Parts That Require Precise Controls And Adjustments

Sensitive parts of an air conditioner (AC) can interfere with its cooling efficiency, energy efficiency, and lifespan if you don't adjust such parts properly. Below are some parts of the AC that a contractor should check and adjust if necessary during maintenance.

Refrigerant

The refrigerant is critical to your AC's operations since it absorbs heat inside the house and dumps it outside. Your AC performs best with the right refrigerant level; too much or too little is dangerous. Excess refrigerant can flood and damage the compressor pistons. Too little refrigerant overworks the AC and increases wear and tear.

You don't have to worry about excess refrigerant if a professional contractor installs your AC, and you don't tinker with the system afterward. Refrigerant loss is a common problem since wear and tear and accidental damage to the refrigerant lines can leak the refrigerant.

An AC technician should check the refrigerant level and pressure during maintenance or if you suspect a refrigerant level problem. The technician will bleed extra refrigerant if it's overcharged. The technician will plug the leak and add some refrigerant if it is undercharged.

Electrical Voltage and Current

The AC has multiple electrical and electronic parts that operate best within a certain range of electrical power. Overvoltage or under voltage can damage the system; ditto overcurrent and undercurrent. For example, the AC compressor might pull more current than it can handle if the voltage drops too low. Such a situation can damage the compressor motor.

The AC technician will measure the electrical current and voltage during maintenance and fix anomalies within the system. External anomalies, such as those on the electrical pane, require an electrician's input.

Thermostat

The thermostat detects ambient temperature and uses the signals to control the AC. For example, the thermostat calls for cooling if the ambient temperature is higher than the temperature you set. The thermostat is only efficient if you calibrate it properly. Otherwise, the AC might not cool your house despite elevated temperatures or cool it too much.

Thermostat calibration ensures that the temperature sensor reads the correct temperature in your home. Wear and tear, temperature fluctuation, power issues, and dirt can interfere with the temperature sensor's accuracy. Therefore, the AC technician will check the sensor's accuracy and calibrate the thermostat, if necessary.

Hopefully, regular maintenance will help you enjoy efficient and affordable cooling throughout the hot months. Contact an AC repair contractor for help if you need maintenance or suspect something is wrong with your cooling system.
