Before turning on your Lexington air conditioner for the first time each year, there are some essential steps which should be taken to improve system performance. Professional preventative maintenance should be performed by a NATE-certified technician each spring, to improve the system’s performance and efficiency, and correct defects.

Home and business owners should also perform an inspection of their own before starting up the system. Below you’ll find the quick checks you should do to ensure your air conditioner has what it needs to perform at its best this summer.

Indoor Air Conditioner Inspection

  • Air filter: Always start the season with a fresh air filter to improve airflow. Replace your disposable furnace filter or give your reusable one a good cleaning.
  • Thermostat: Switch your thermostat to cooling mode. If it’s programmable, either set new temperature schedules or review existing schedules to verify they meet your current needs. Replace batteries and/or test the thermostat’s electrical connection.
  • Vents: Go through your home or business and remove any items blocking registers and return air vents indoors. Carpets, furniture, curtains, and other items can easily get in the way, causing airflow restrictions.
  • Drain line: Condensation should exit your cooling system through the condensate drain lines. Prevent backups by treating your drain line – run a cup of chlorine bleach through, rinsing with a gallon of water.
  • Ductwork: Inspect ductwork you can see, looking for gaps, fallen sections, and wear. You’ll want to have them sealed properly to prevent conditioned air from escaping, lowering efficiency.
  • Power: Make sure your air handler’s power switch is set to on, and your breakers powering the cooling system are not tripped.

Outdoor Air Conditioner Inspection

  • Condenser: Remove all items and debris from the area surrounding your condenser. Gently brush or rinse away yard debris which has gathered on the condenser’s fins and exterior. Cut away grass, vines, and other vegetation surrounding the unit. Keeping your condenser clear will improve airflow through the system, boosting performance.
  • Refrigerant lines: Refrigerant lines are insulated to improve system performance. Check to ensure it has not degraded or been damaged, and have it repaired if needed.
  • Power source: Check that the condenser’s outdoor switch is set to ‘on’ and the unit is plugged in. Inspect wiring for damage and loose connections.
