air conditioner repair

As we peel off our winter sweaters and begin to don tank tops and shorts in anticipation of summer, it may be time to dust off the air conditioning unit. A functioning AC is the staple of surviving California summers – how else are you supposed to endure blistering heat if not from the comfort of your 67 degree home? Inevitably, your hard-working air conditioner will need a bit of maintenance to cool your home efficiently and effectively. Below are the most common air conditioner repair issues you may encounter this summer.

No Airflow

Without regular maintenance, your air conditioner’s filter can become clogged with pet hair, dust, mold, and other contaminants. The debris restricts the air that is able to move in and out of the unit. Much more energy is required to run your air conditioner as a result of this poor airflow, and the contaminants in the filter can lead to poor air quality in your home. The solution is to remove the air filter from the unit and give it a good cleaning.

  • Use a screwdriver to open the HVAC unit and remove the air filter.
  • Use a vacuum nozzle attachment to clean the debris from the filter, paying special attention to edges where more grime may have accumulated.
  • For a deep clean, fill a sink with equal parts water and vinegar. Soak the filter, let dry, and replace within the HVAC unit.

Won’t Turn On

If your AC unit won’t activate, there could be an electrical issue, unconnected cord, or faulty thermostat. Save yourself an air conditioner repair fee by checking that a few key parts are properly functioning.

  • Make sure that the cord connected to your furnace is correctly plugged into the wall outlet.
  • Check the batteries in your thermostat. Replace with new batteries if necessary.
  • Reset the circuit breaker to make sure that power is going to your HVAC unit.
  • Ensure that all the switches on your unit are in the ‘on’ position.

It’s Not Cooling

A unit blowing warm air through the house could have a blockage somewhere in the system or low refrigerant levels. To effectively cool your home, you will need to check for the following issues.

  • Signs of low refrigerant are ice forming on the evaporator coils. Without enough refrigerant, pressure and temperature both drop, causing cool refrigerant to flow through the coils. Moisture in the air will freeze on the coils as a result. The most common cause of low refrigerant is a leak, so check the line for bubbling or dripping. If signs point to low refrigerant, you will need to call a professional.
  • If your air filter is seriously dirty, debris can get through and clog the cooling coil of your AC system. Cleaning with compressed air or a brush can often be enough to remove the blockage. If you suspect a blockage elsewhere in the system, consult with a professional.
