Why systems struggle
Ask anyone who services heating and cooling where the problems live and the answer is the same: rarely in the equipment, almost always in the loop around it.
- 1 Thermostat — The season’s odometer — a hundred cooling days pass through it.
- 2 Return and filter — The lungs, and the first thing a retrofit house sized too small.
- 3 Air handler and furnace — Up in the attic, asleep nine months, asked for everything in December.
- 4 Coil and condensate drain — Litres of Gulf moisture a day, all leaving through one narrow line.
- 5 Attic ducts — The coldest air in the house, commuting through the hottest room on the property.
- 6 Outdoor unit — Full sun, full load — where August culls capacitors by the thousand.
The six
What this region does to a system
A hundred-day cooling season that ages equipment by the hour. Gulf air that makes drying the house half of every cooling job — and hands its moisture to one narrow drain. Ducts crossing attics that bake all summer. A heat wave every August that culls capacitors by the thousand. And a furnace asked to wake, unserviced, on the first cold morning. Most of what ends a system here traces back to one of those.
