Full system changeout, Scottsdale
The problem: a 16-year-old system on its third repair in two summers, with two upstairs rooms that never cooled.
What we found: the load calculation showed the old unit was oversized, and the second-floor return was undersized, so the equipment short-cycled while the far rooms starved for air.
How it finished: right-sized variable-speed system, corrected return and sealed ducts, permitted and inspected. Upstairs rooms now hold setpoint within two degrees of downstairs.
