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

This topic comes up regularly across Westlake, from Tarrant & Denton Counties to the rest of Tarrant & Denton Counties. Here's what's worth knowing if you're local.

For Westlake Homeowners

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

Westlake is a small, upscale community split between Carroll ISD and Northwest ISD, known for larger custom homes near the Solana office corridor and Circle T Ranch area. Larger, custom-built homes here often call for a proper Manual J load calculation rather than matching a prior system's size out of habit.

Westlake 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.
