March through May is when Gulf Coast humidity climbs back above 70% and the first 90° afternoons arrive. A system that limped through last summer will fail in the first real heat wave — spring is the window to catch it early.

Triple-digit heat index. Grid under strain. Storm season live.
June through August the heat index along Galveston Bay regularly tops 100°, air conditioners run near-continuously, and hurricane season is active. This is when deferred maintenance turns into 9 PM breakdowns and when an outage means a hot, dark house.

Short, sharp freezes are the Gulf Coast's hidden risk.
Winters here are mild — until they aren't. Hard freezes like February 2021 showed how fast Gulf Coast homes lose heat and power together. Heat pumps, furnaces, and panels all work hardest during cold snaps, and generator demand spikes with every winter storm warning.

Outdoor Condenser
Salt air and 9-month cooling seasons are brutal on outdoor units. We catch corroded coils, weak capacitors, and low refrigerant before they become a dead compressor in August.
- Unit sounds louder than it used to
- Ice on the refrigerant line
- Warm air from the vents

When our AC went out in the middle of a hot Texas July day of 95+, Mackey Services showed up the very same day. Their technician (Smiley) was courteous, explained everything clearly and got to work immediately. I was impressed by how quickly he diagnosed the problem and how efficiently he fixed it. Throughout the whole visit he was responsive to my questions and very professional. I left feeling confident that my ac system is in great hands and especially grateful for the quick same-day service. I highly recommend Mackey Services for any HVAC repair needs.
