Air conditioning is essential for maintaining a comfortable living environment here in Alberta, especially during the sweltering summer months.

Do It Yourself vs. Calling in the Pros

Repairing an air conditioner can be a daunting task, but with the right knowledge and tools, you can tackle basic problems yourself. But it’s also important to remember that certain repairs will require the skills of an experienced AC technician.

DIY AC Repair

DIY air conditioner repair doesn’t have to be difficult. But before you start, it’s important you ensure your safety:

  • Turn off the power to the AC unit at both the thermostat and the breaker.
  • Use appropriate safety gear, like gloves and goggles.
  • Be aware of sharp edges inside the unit.
  • Handle all components (especially electrical) with care.

AC Not Turning On, or Cycles On and Off

If your air conditioner is having issues turning and staying on:

  • Check that the thermostat is properly set, and the temperature is lower than the room temperature.
  • Inspect the circuit breaker and reset if it’s tripped.
  • Examine the AC switch, some units have a switch near the furnace or air handler. Ensure it’s in the “on” position.

AC Not Blowing Cold Air

  • Replace or clean air filters – Dirty filters can obstruct airflow, so most air flow issues can be fixed by quickly replacing or cleaning them regularly.
  • Clean the coils – Dirty condenser coils can inhibit cooling. Simply turn off the power and gently clean the coils with a soft brush and coil cleaner.

AC Leaking Water

If your air conditioner is leaking water:

  • Algae and mold growth can clog the drain line, leading to leaks. Clear it using a wet/dry vacuum or a special drain line brush.
  • Inspect the drain pan and if it’s damaged, it may need replacing.

If you’ve attempted to resolve minor issues yourself without success, call Action Furnace to avoid further damage or safety risks.
