Getting a Chandler System Ready for Summer

An air conditioner in Chandler carries a long cooling season, and most of what stops it in July starts as a small problem in March. An AC tune-up in Chandler is a scheduled look at the parts that fail most often here, done while a replacement part is a routine swap instead of an emergency call.

What We Check

Part What we look for Why it matters
Run capacitor Measured against its rating The most common cause of a no-cool call
Contactor Pitted or burned contacts Makes the outdoor unit cut out
Outdoor coil Dust and debris packed in the fins A dirty coil raises pressure and run time
Refrigerant charge Measured, not guessed Low charge means a leak, which we report
Condensate drain Flushed and tested Stops overflow into an attic or closet
Airflow and filter Checked at the blower Restricted airflow can freeze the indoor coil

Two-Story and Two-System Homes

Many Chandler homes have two systems, or one system feeding two floors. We check both units and the temperature difference between floors, because uneven cooling is often an airflow or duct issue that a tune-up can catch early.

Timing

Spring is the best time, before the first 100-degree week. A second visit after monsoon season makes sense for units near open lots or new construction, where dust builds up fast.

Between Visits

  • Change the filter every one to three months, more often with pets or nearby construction.
  • Keep about two feet clear around the outdoor unit, including plants and stored items.
  • Rinse the outdoor coil gently with a garden hose after a dust storm. Never use a pressure washer on the fins.
  • Look for water where the condensate line ends outside while the system runs. No water on a hot day can mean a clog.

Common Questions

How often should I book a tune-up?

Once a year for cooling, ideally in spring. Heat pumps that also heat in winter benefit from a fall check too.

Do new systems need tune-ups?

Yes, and with Adams they are covered: every new unit we install includes three years of maintenance.
