For Highland Village Homeowners

Highland Village, part of Denton County, has its own mix of established and newer neighborhoods, and that mix shapes how often we see the specific issue this guide covers. Either way, the same honest approach applies: diagnose first, explain clearly, and never push work that isn't needed.

Highland Village, zoned to Lewisville ISD, sits along Lake Lewisville with a mostly established, fully built-out housing stock. Lake-adjacent humidity tends to push cooling systems harder through the summer than a similar home further from the water.

Highland Village FAQ

Does a bigger AC system fix this problem?+

Not necessarily, and it can create new problems. An oversized system cools quickly without properly managing humidity, which can leave a home feeling clammy even at the set temperature. The better answer is usually a correctly sized system paired with good insulation and maintenance, not simply going bigger.

Should I lower my thermostat setting during extreme heat to compensate?+

Setting it well below a realistic target usually just means the system runs constantly without ever satisfying the thermostat, which doesn't actually get you there faster and adds unnecessary wear. A more realistic setting for the conditions, combined with good airflow and shading where possible, is usually more effective.
