Why Can't My AC Keep Up When It's Over 100 Degrees Outside?: A The ColonyHomeowner's Guide

If you're a homeowner near Lewisville ISD or elsewhere in The Colony, this guide walks through what we cover with The Colony customers on this exact topic, based on the calls we take throughout Denton County.

For The Colony Homeowners

Between established neighborhoods and newer construction, The Colony has enough variety in home age and system type that we rarely assume anything about a system before actually looking at it.

The Colony, zoned to Lewisville ISD, sits along Lake Lewisville with a mostly established housing stock built out over the past few decades. Lake-adjacent humidity is a real factor here, worth accounting for during any cooling diagnostic or maintenance visit.

The Colony 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.
