Why Proper Sizing Matters for Oak Lawn Homes
Oak Lawn features a rich variety of housing from post-war ranches and split-levels to modern construction. Many homes built between the 1940s and 1980s feature original ductwork that may be undersized or restrictive. Finished basements, family room additions, and updated windows have changed heating and cooling loads significantly over the decades.
An oversized HVAC system costs more upfront, short-cycles (starts and stops frequently), creates temperature swings, and reduces humidity control. An undersized system runs constantly, struggles during temperature extremes, and wears out faster.
We size systems correctly using Manual J load calculations that account for:
- Home square footage and layout
- Insulation levels (attic, walls, basement)
- Window quantity, size, and orientation
- Air infiltration and ductwork condition
- Occupancy and internal heat gains
- Local climate data (Oak Lawn's hot, humid summers and cold winters)
