North Texas asks more of an air conditioner than almost anywhere else in the country. Extended stretches above 100 degrees, high humidity and storm-driven power events wear systems down season after season. Graco Heating & Air has kept Lewisville and North Texas homes cool for over 30 years, and every side of that work lives here: fixing what has broken, replacing what has reached the end of its life, and keeping healthy systems healthy. Our licensed technicians work under TX License #TACLA00017212E.
Cooling Built for Texas Summers
Systems here run harder and longer than the design assumptions most equipment ships with. That shapes how we diagnose problems, how we size replacements, and what we look for on a maintenance visit.
Long stretches above 100 degrees put constant load on compressors and capacitors. Capacitor failure is one of the most common calls we take in the Texas heat.
High humidity levels demand proper dehumidification. An oversized system short cycles and leaves the house cool but clammy, which is why sizing matters as much as capacity.
Swing seasons need flexible capacity. Variable-speed and inverter equipment holds comfort steady through the mild days that bracket a North Texas summer.
Spring and summer storms bring surges and brownouts that damage control boards and contactors. Surge protection is worth discussing on any new install.
Tell us what the system is doing and we will point you to the right service. If your home has no cooling at all in extreme heat, start with our emergency AC repair page.
Your comfort is within reach with flexible financing options from GoodLeap and Service Finance.

Choose Your Service
Three ways we keep North Texas homes cool, from the emergency call to the annual tune-up.
No cooling, weak airflow, strange noises or a breaker that keeps tripping. We diagnose the actual fault with electrical testing, refrigerant pressure analysis and airflow measurement before we quote a repair.
Replacement starts with a load calculation, not a guess based on the box that is already there. We are Armstrong Air ProTeam dealers and a Daikin partner, and we size for the actual heat gain of your home.
A spring tune-up before cooling season is the cheapest hour you will spend on your system. Coil cleaning, refrigerant charge verification, electrical testing and airflow checks catch the failures that turn into July emergencies.
Start Here
Check the thermostat setting and the circuit breaker first. If both look right, book AC repair. When a house has lost cooling entirely during extreme heat, our emergency AC repair page explains how we prioritize those calls.
Once a system passes the 12 to 15 year mark and repair costs climb toward half the value of a replacement, it is worth pricing AC installation. Our guide on AC repair versus replacement in DFW walks through the decision.
Book AC maintenance in spring, before the first stretch of triple-digit days. Our maintenance plans cover the visit and the reminder so it does not get away from you.
Uneven rooms and high humidity are often duct and airflow problems rather than equipment problems. Ask about duct cleaning, indoor air quality options, or a ductless mini-split for the room that never keeps up.
There is a difference, and we are clear about it.
Our technicians service all major residential and light commercial cooling equipment, whoever installed it:
