Local conditions that affect your system
Long cooling season
AC runs from spring into fall, so annual maintenance and capacitor checks prevent most peak-season failures.
Hard water
Mineral-heavy water affects humidifiers and some condensate pumps.
Freeze events
Rare deep freezes push heat pumps onto auxiliary heat and can damage exposed lines.
