Northshore’ hot-humid climate puts unique demands on air conditioning. With summer design temperatures in the low 90s°F and high dew points, your AC runs heavily, about 2,650 cooling degree days per year compared to just 1,500 heating degree days. That long cooling season means your system carries both sensible load (lowering temperature) and latent load (removing moisture). If either is neglected, comfort suffers.
An oversized air conditioner will cool the air quickly but shut off before it removes enough humidity, leaving your home clammy and encouraging mold and allergens. An undersized system runs constantly, struggles to maintain temperature on the hottest days, and wears out faster. Proper sizing using Manual J load calculations tailored to your home’s insulation, windows, orientation, and occupancy ensures the equipment matches the job. Quality systems with strong latent capacity handle Gulf Coast humidity effectively, keeping indoor conditions dry and comfortable even when it’s 95°F and muggy outside.
In this climate, the difference between a properly designed system and a rushed installation shows up every summer.
