Air Conditioning maintenance is a best practice.  The AC Tune-Up increases the systems efficiency, prevents breakdowns and saves money.

The main Air Conditioning components are the outdoor unit called the Condenser and the indoor unit called the Evaporator.

  1. The Outdoor Unit pressurizes the gas refrigerant into a liquid.
  2. Hot refrigerant travels through its fan blow coils to release the heat.
  3. An expansion valve decreases pressure causing the refrigerant to change back to a gas and cool down.
  4. The cool gas travels to the evaporator coils.
  5. The Indoor Unit’s blower sends the cool air into the Air Duct system.

The Condensers job is to transfer heat to the outside air and compress the refrigerant to be sent to the evaporator.

The Evaporators job is for the coils to get cold and the blower to propel the cool air throughout the Air Duct system.

Debris over time clogs the Outdoor Unit’s cooling coils causing inefficiencies.  Low refrigerant level causes compressor damage, loss of cooling and expensive operation.

The AC tune up includes:

  • Calibrating and leveling thermostat
  • Cleaning filters as needed
  • Lubricating and inspecting bearings for wear
  • Inspecting indoor coil (if accessible)
  • Inspecting condensation drain
  • Inspecting the condenser coil
  • Monitoring operating pressures of refrigerant
  • Inspecting safety devices for proper operation
  • Inspecting disconnect box for proper rating and installation
  • Tightening all electrical connections
  • Inspecting electrical for exposed wiring
  • Inspecting and testing capacitors
  • Inspecting fan blades
  • Cleaning condenser coil and removing debris
  • Inspecting service valves for proper operation
  • Measuring temperature difference between supply and return
  • Inspecting the Air Duct System for cleanliness and energy loss
