Westlake estate, re-engineered end to end
A 6,400 sq ft hillside home with three aging systems, hot-spot bedrooms, and $900 summer bills. We redesigned it as one zoned, variable-speed plant.

The house had been added onto twice, and its comfort showed it: three mismatched systems fighting each other, two bedrooms that never held temperature, and ductwork snaking through a 140° attic.
We started with a full Manual J and duct static survey, then replaced the patchwork with two Carrier Infinity variable-speed systems and a six-zone control plan. Supply trunks were re-routed and sealed, returns doubled in the starved wing, and the whole plant commissioned over two days with measured airflow at every register.
The owners' first full-summer electric bills came in 38% lower — and the primary suite finally holds 71° at 3 PM in August.
