Frequently Asked Questions

In Southern California's hot climate, air conditioning systems should be maintained at least once a year, ideally before summer begins. Regular maintenance helps identify issues early, prevents breakdowns during peak cooling season, and extends system lifespan. At A Plus Air Corp, we focus on transparent inspections without unnecessary add-ons.
