What Does an HVAC Technician Do During a Tune-Up?

There are many mysteries in life: Why does your dentist talk to you when you can’t respond? Why do people moan when stretching? Why do people say “heads up” when you should duck? What does an HVAC technician do during a tune-up? Dixie Electric, Plumbing & Air can’t help you with the first three, but we can help you with the last one.

System Inspection

Most HVAC tune-ups will start with a visual inspection. The technician undergoes comprehensive training to identify potential problems. He or she will look for signs of wear and tear in key components that could cause a breakdown.

Cleanliness is Next to Godliness

It’s one of the great exaggerations in life, but cleaning is a huge part of an HVAC tune-up. Even when filters are changed regularly, the evaporator coil, blower wheel, condenser coil, and other components get dirty. Whether it’s heating or cooling, dirt reduces efficiency and causes the unit to work harder. If a thorough cleaning is not part of the HVAC maintenance in your Auburn or Montgomery, AL home, then the technician is not doing his or her job correctly.

Then Things Get More Technical

HVAC maintenance is far more than a quick visual inspection and cleaning. The technician also performs a series of technical tests to make sure the heating or cooling system is operating according to manufacturer specs. Here are a few examples:

  • Verify refrigerant level is correct
  • Clean condenser coil
  • Condensate drain line and pan
  • Visual inspection of exposed duct
  • Inspect heat exchangers (furnace) for dangerous cracks
  • Check carbon monoxide detectors
  • Inspect and tighten electric terminals
  • Confirm the thermostat is accurate
