Carrier out, Comfortmaker in

Job: full split-system changeoutArea: Dallas–Fort WorthNew: condenser, R-454B air handler, Air Scrubber, thermostat

The old Carrier system was worn out, so we replaced both halves. New outdoor unit and a matched air handler running R-454B, the newer low-GWP refrigerant. We added an Air Scrubber for cleaner indoor air, pressure-tested with nitrogen before charging, and kept the floors covered the whole time.
