An AC tune-up is a general service a professional technician provides for air conditioning systems. The tune-up entails examination, sanitization, and calibration and helps your air conditioner operate at its optimal capacity while checking for underlying problems, notes Foothills Properties Management company. Here are 5 common air conditioning repair tune-ups:
Inspection of Components
A repair technician checks the condenser and evaporator coil for dirt and damage. During air conditioning repair, they inspect the compressor to check that it is working and does not show signs of wear. Fan motors and their corresponding blades are checked for balance and lubrication requirements. Technicians check refrigerant lines for leakage or signs of wear and tear.
A technician checks the air filter and advises clients on whether it should be replaced. They test the thermostat for efficiency and functionality. Circuitry and wiring connections are checked for loose connectors or evidence of excessive heat. If the technician suspects problems with drainage, they check the drain line and condensate pan for blockages. The technician also inspects the ducts for any signs of leakage or inadequate insulation that may hinder the AC system’s performance.
Lubrication of Moving Parts
Lubrication is critical to AC equipment performance, minimizes wear and tear, and enhances the equipment’s lifespan. Air conditioners have a number of moving components that should be lubricated periodically. A compressor’s pistons or scrolls pressurize refrigerant, and the oil that lubricates these parts must be reapplied to keep the air conditioner working properly. Fan motors in both indoor and outdoor units have bearings that may require greasing. Repair technicians use oils and greases that can withstand high temperatures and last for long periods. Some modern systems have self-lubricating parts and may require less maintenance. In older models, technicians may need to apply lubricants to the damper linkages and other mechanical parts.
Refrigerant Level Check
The refrigerant level in an AC system affects the efficiency of the cooling process, the durability of the system, and its energy consumption. A technician may be concerned that refrigerant levels are low if warm air is blowing from the vents, there is ice buildup on the evaporator coil or refrigerant lines, or hissing or bubbling noises are coming from the air conditioner. If the refrigerant level is low, the air conditioner’s cooling capacity could be low, or the compressor could be damaged. When levels are low, technicians look for leaks, make any necessary repairs, and fill the system to the manufacturer’s recommended level.
Thermostat Calibration
Thermostats can lose calibration over time, causing the air conditioner’s sensor to misread the room’s temperature. To determine if the AC’s thermostat is calibrated correctly, repair technicians compare it to a calibrated thermometer and match the AC system to the accurate temperature if there is a discrepancy. Digital thermostats often require a program to be reset, while traditional mechanical models may need dial modifications. Correct calibration directs your AC system to switch on and off according to its program, leading to temperature stability and reducing the strain on the AC equipment.
Electrical Connections Tightening
When examining electrical connections, many repair technicians begin with a general assessment of the AC system to identify signs of wear, rust, or physical damage. Using multimeters, technicians can check whether connections hold continuity or sufficient resistance to allow the proper flow of electricity. A multimeter’s camera can capture hot areas where connections may be loose or poorly made. If wires or connectors are loose, technicians can adjust or replace them as needed.
For dirty connections, contact cleaners are used for efficient cleaning, or dielectric grease may be applied to avoid future corrosion. In areas that are difficult to access, technicians may utilize borescopes or flexible inspection cameras. Stress points, such as compressor terminals and fan motor connections, are often inspected thoroughly for connectivity issues. After assessing and repairing electrical connections, operational tests are conducted to check that all electrical parts are working as required.
Schedule Air Conditioning Repair
Frequent air conditioner checkups can increase the service life of your cooling system and minimize the need for replacement. Tune-ups also help increase energy efficiency, reducing electricity consumption costs and negative effects on the environment. Using professional skills to clean, repair, and manage complicated AC systems, certificated technicians help keep your AC unit running at maximum efficiency.
