Irving is the northwest arc's large middle city, and it holds two eras in one border. North of the highway sits Las Colinas, the master-planned district of canals, office towers, and planned subdivisions built from the seventies forward. South of it sits the older Irving of postwar tracts and working streets, houses built for the airport decades and now deep into their later systems. The airport itself sits at the city's western edge, and the whole map lives in the Trinity bottoms' humid air.

The stock writes two calendars. The planned north runs the corridor calendar: bigger plans, two systems in the largest, equipment aging in the chorus of its building years, zones in the later subdivisions. The older south runs the ranch calendar at larger scale: second and third systems, ducts drawn for the first, the afternoon fade in houses whose west glass gains heat faster than their equipment sheds it. Between them, the townhome and condo pockets near the entertainment district carry smaller systems in closer quarters, closet units and shared walls.

Heating follows the same split: furnaces in the older south waking after rest, heat pumps in the planned north carrying the load until the strips join in, and February 2021 as the week both halves remember. Call Call for same-day help, or begin with the free estimate.
