What Happens During an HVAC Tune-Up?

HVAC Sercice

Do you know the last time you’ve had an HVAC tune-up? Your HVAC, an acronym for Heating Ventilation and Air Conditioning, is a huge factor in keeping a clean and healthy home. You may think that your duct system in your house is sealed off and constantly blown out, so as long as you have a filter on the intake, things remain clean, right? Well, yes and no: On a daily average, hardly anything settles inside your HVAC system. However, over time, annoying allergens and possibly harmful molds can accumulate and do not get “blown out.”

Fortunately, cleaning out the systems and getting an HVAC tune-up isn’t difficult. It can take around 90 minutes to have a complete operation accomplished and leave you breathing cleaner and healthier air. Below are what actually happens during an HVAC tune-up, providing a view into what goes on “behind the scenes” of your AC.

Electrical System

  • Calibration and leveling of the thermostat
  • Monitoring of refrigerant operating pressure
  • Voltage and amperage and wiring check for fan motor and compressor
  • Inspection of condenser coil and capacitors
  • Inspection of electrical system for exposed wires, burned/pitted contacts, and tight connections
  • Ensure proper operation of all safety devices
  • Proper installation of disconnect box and rating check


  • New filters
  • Inspection and lubrication of fan blade and bearings
  • Clean and debris removal of indoor coil and condenser coil
  • Ensure proper operation of service valves
  • Inspection of duct system for cracks and leaks
  • Flush and treat the condensation drain with anti-algae solution

With an HVAC tune-up, you can rest assured that the air you breathe is clean. This keeps you and your family healthier longer. Knowing that your HVAC is running free of malfunctions and you are running it efficiently will save you money in the long run and keep your utility bill down.
