Warning Signs That Your Air Conditioning System Is In Trouble

Living in the San Diego area, you rely on your air conditioner to stay cool in the summer months. Keeping your HVAC equipment properly maintained can help prolong the life of the unit and ensure good performance, though minor repairs are inevitable. Here are some warning signs to watch out for, all of which can signal bigger problems with your air conditioning system.

  • Excessive energy bills: The cost of energy frequently rises, but if you notice unusually high energy bills, something is amiss. It may simply be that you need to replace your unit with a newer high efficiency model.
  • Unpleasant odors: Any sharp, pungent or burning smells coming from either your vents or around the unit itself may indicate burnt wiring, a short in the electrical system or worn out bearings.
  • The presence of ice: If the condenser or the condenser line is iced over, it can signal a shortage of refrigerant. Ice may also be a sign of a substantial blockage in the primary supply duct.
  • Excessive cycling during mild weather: If the unit is continually cycling when there is no call for cool air, your air conditioning system could be incorrectly sized. 
  • Unusual noises: While rattling may indicate a loose screw on one of the panels, a noise such as squealing, grinding, screeching or clicking could be anything from a bad fan belt to a compressor or motor issue.  
  • A lack of cool air: If both the fan and compressor are working but there’s no movement from the vents, there may be a problem with the level of refrigerant. You may have a leak or the unit may have been improperly charged during service. Another possibility is compressor failure.
