Rooftop unit service

Rooftop units combine cooling, heating and the blower in one cabinet. Common failures are belts, condenser fan motors, economizer dampers stuck open, and gas heat ignition. Replacements usually need a crane and a curb adapter.

  • Same-day appointments when available
  • Licensed HVAC contractors
  • Written price before any repair

Economizers stuck open let 110°F outdoor air in and are often missed.

Plan replacements for spring or fall to avoid peak-season crane scheduling.
