Flower Mound 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.
