Built for our climate

Why HVAC works harder on the South Texas coast

Corpus Christi's subtropical Gulf climate is one of the most demanding in the country for heating and cooling equipment. Here's what your system is up against — and why local expertise matters.

95°F+

Summer highs

Corpus Christi summers regularly push past 95°F with a heat index well over 100°F, so cooling runs nearly nonstop from May through October.

~75%

Average humidity

Gulf moisture keeps relative humidity high year-round, putting extra strain on systems and making humidity control essential for real comfort.

Salt air

Coastal corrosion

Living near the bay means salt-laden air corrodes outdoor coils and components faster — regular maintenance protects your investment.

Feb 2021

The hard freeze

Winter Storm Uri proved that even the coast needs reliable heat. We make sure your system is ready when the rare freeze arrives.
