One of the most common air conditioning problems is improper operation. If your air conditioner is on, be sure to close
your home’s windows and outside doors. For room air conditioners, isolate the room or a group of connected rooms as much as possible from the rest of your home. For a list of common air conditioner problems and what to look for, check out our Energy Saver 101 infographic on home cooling.
Faulty installation, poor service procedures, and inadequate maintenance are other common problems. Improper installation of a central air conditioner can leave you with improper or low airflow and leaky ducts. Often, the refrigerant charge (the amount of refrigerant in the system) does not comply with the manufacturer’s specifications. If proper refrigerant charging is not conducted when the unit is installed, the performance and efficiency of the unit is impacted.
Unqualified service technicians often fail to diagnose refrigerant charging problems compound existing problems by adding refrigerant additional refrigerant to a system that is already fully charged. Learn what to ask for when hiring a technician to maintain your air conditioner.
Air conditioner manufacturing companies generally make high quality products, long lasting products. If your air conditioner fails, check to insure that any fuses aren’t blow or circuit breakers tripped. Let the unit cool down for a 10 minute period before resetting any breakers. If a air conditioner’s compressor stops on a hot day, it is a possibility that the high-pressure limit switch could have tripped; reset it by pushing the button, located in the compressor’s access panel.
