Comments Off on My Home’s AC Unit Isn’t Blowing Cold Air?

With temperatures hitting 100 degrees, the last thing you want is a blast of hot air when you return home.  When your air conditioning is working, but not running cold air, there is a good chance that your condenser is dirty.   Here is how to clean your condenser:

  • Shut down all power to the unit – your condenser should have a metal box attached that has a disconnect switch. Also turn off the circuit at your main electrical panel.
  • Unscrew and remove the top and side grilles. Make sure you don’t disturb any wires connected to the fan.
  • Brush the fins and coils – with a soft brush, clean the fins and coils of any debris or dust
  • Wash the fins and coils – cover the wiring and the motor with a garbage bag and duct tape then use a garden hose with a nozzle to clean out (don’t use high pressure or you will bend the coils)
  • Replace the panels and grilles – use a level to make sure the unit is properly balanced so you don’t have drainage problems.
  • Reconnect the unit- turn the thermostat off before reconnecting the power to the unit, and then re-engage the power to the unit at the main service panel.
