Larger homes, two separate systems, and a forest canopy overhead. The Woodlands produces a distinctive pattern of air conditioning problems, and one of your two systems is almost certainly doing all the suffering.

The Woodlands runs to larger homes than most of the Houston area, and a great many of them are two storeys with two separate systems — one for each floor. That arrangement is sensible, and it produces a specific pattern of calls.
The upstairs system does far more work. It fights heat rising from below and an attic that reaches extraordinary temperatures, and its ductwork usually runs through that attic. It will wear out first, cool less well, and generate most of your service calls. If one of your two systems is the problem, it is almost always that one.
When a contractor recommends replacing both systems together, ask why. Sometimes it is genuinely better — matched equipment, one install, one permit. Often the downstairs unit has years left in it, and replacing it is money spent early rather than money saved.
The Woodlands was built into forest and kept it, which is one of the reasons people live here. For air conditioning it is mostly a benefit: a condenser in shade runs cooler and more efficiently than the identical unit baking in full sun.
The cost is debris. Pine needles, leaves and seed fall pack into the condenser fins, and a coil that cannot shed heat makes the compressor work harder for less cooling. Twice-yearly rinsing matters more here than in an open subdivision — garden hose, from the inside out, power off, never a pressure washer.
Two things commonly go wrong in these attics and both are cheap to find and expensive to ignore.
Both are visible to anyone willing to go up with a light, and both can be fixed in an hour.
