Air conditioners keep rooms cool and comfortable and make hot summers bearable. But air conditioners need regular maintenance. Air conditioning units also develop issues that mandate prompt fixes. That’s why air conditioner services have become prominent today.
The HVAC industry has always enjoyed a surging demand for retrofitting and new installations during summertime. The COVID-19 pandemic outbreak has severely affected the global supply chain and logistics, forcing the heating, ventilation, and air conditioning (HVAC) industry to face a severe shortage of components. Due to the large-scale adoption of energy-efficient air conditioners that shrink costs and power wastage, the demand for air conditioner maintenance services is evergreen.

Here’s a detailed guide on air conditioner maintenance services for field agents. Field technicians can follow these best practices to enhance air conditioner troubleshooting and make quick fixes.
Routine air conditioner maintenance service involves cleaning the air filter and tune-ups. The optimal time for these air conditioner services depends on the unit’s model and the usage pattern.
Perform the following tune-up tasks as part of a standard air-conditioner maintenance service:
The telltale sign for scheduling a tune-up is the airflow coming out of the unit becoming weak. It is a good practice to inspect and tune the air conditioner once a year, anyway.

When a client calls in and reports an issue with their air conditioning, perform these basic checks upfront as the first step of air conditioner troubleshooting:
A common complaint regarding air conditioning is indoor water leaks. Water backs up from the drainpipe and leaks through the inside because of a clogged condensate drain. Algae or fungi build-up and dust accumulation cause the blockage.
Unclog the clogged condensate pipe using a wet or dry vacuum. Pouring vinegar or recommended fungicides kill the fungi or algae build-up.
Air conditioners produce water when it cools the air. But water leakage indicates problems with the unit. A dry air filter, broken condensate pan, a bad seal, or even improper installation could cause puddles of water right under the compressor.
Make a thorough inspection and fix the broken parts. Redress the issue to pre-empt its escalation.
Wet filters, clogs in the condensate drain, or fungus build-up could cause the air conditioner to emit a foul odor. Decaying animals, such as rats, trapped inside the unit, stink. The solution is to clean the ducts at regular intervals.

If the air conditioner does not receive enough air, the evaporator coil freezes and the air conditioner stops working.
Diagnosing issues related to frozen coils requires visual inspection of the damage. Thaw the coil by not using the air conditioner for twenty-four hours. A hair dryer helps speed up the process.
Freon, the refrigerant used inside air conditioning, cools the air. This refrigerant may leak because of holes in the pipes or faulty insulation. Leaked Freon reduces the efficiency of the air conditioner. It also poisons the immediate environment.
Freon leaks may be major or minor. Minor leaks need only a simple patch up over the source of the leak and refilling the Freon. Do not overcharge or undercharge the refrigerant during recharging.
Major leaks indicate significant faults in the piping system. The fix is to change pipes.
As air conditioners run on electric control systems, a faulty thermostat or power issues can turn the unit on and off frequently. This wears off the compressor and fan system early.
The air conditioning unit starts when the compressor, condenser motor, and blower engine connects. Corrosion of wires or terminals may prevent the compressor and motor from turning on. To troubleshoot the issue, inspect the electrical connection for breaks or other faults.
The fan is a significant component of the outdoor unit of the air conditioner. If the fan does not work correctly, heat transfer does not take place properly. The compressor may overheat, and the AC unit may stop working. Left unattended, it could even damage the compressor and cause replacement of the entire unit.
The fan not working could result from a loose component or an issue with the wiring. As the first step of air conditioner troubleshooting, remove the case of the outdoor unit and make a visual inspection.
The air conditioner may emit strange noises, such as a loud banging or clanging. These are usually indicators of a severe problem, such as the fan hitting the frame or some other mechanical parts failure. Diagnose the issue through a thorough visual inspection, and make the necessary fixes.
