Professional Air Conditioner Inspections: What Technicians Check

Let’s take a look at the “inspection” part of maintenance. It may make sense that an air conditioner requires a “tune-up” before the harsh heat of summer arrives. But what’s important about inspections? What do technicians look for, and isn’t this something you can do on your own?

To answer the second part first, inspections of any complex mechanical equipment requires skilled technician with appropriate training and tools. Air conditioners are intricate pieces of refrigeration technology, and amateurs can’t hope to be able to diagnose issues with them. It takes the eye and the knowledge of experts.

As to what a technician looks for, it’s a long list. During maintenance, technicians go through an extensive checklist to analyze all the major components. Below are a number of the specific inspections technicians do to find out if an air conditioner is in need of repair service or additional tune-up work:

  • Corroded or loose electrical connections: Many of the most common malfunctions in air conditioning systems are electrical. Moisture and chemicals in the air can cause electrical wiring and connections to corrode, which will eventually cause multiple systems to fail and the AC to shut down. Technicians look closely for this, as well as for wiring that is coming loose. Sometimes all it takes to fix problems is tightening the connections.
  • Motors in need of lubrication: Technicians pay close attention to the motors in an air conditioner that operate the fans and the compressor. Strain on motors can cause overload and burnout. If motors are dusty or losing lubrication, technicians will lubricate them—or recommend replacing them entirely.
  • Refrigerant pressure and levels: An air conditioner comes with a factory-set level of refrigerant, known as its charge. If technicians find the refrigerant charge has dropped during inspections, they’ll know there are leaks somewhere that must be fixed. This is a critical repair: without it, the compressor is in danger of an expensive failure that may even require replacing the whole AC.
  • Blower components: The blower is what moves air through the coils of the AC and into the ductwork. Dirty or failing blowers cut down on efficiency and airflow.
  • The thermostat: Yes, the thermostat is a part of your HVAC system, and it needs to be checked as well to make sure that it hasn’t become miscalibrated. Even a small miscalibration will start to drain energy needlessly.
