HVAC, plumbing & electrical in Lewisville, TX

Your local team in Lewisville

Lewisville is our home base. Graco Heating & Air is headquartered at 985 East Highway 121, so when a system fails at the worst moment, we are not driving in from across the Metroplex — we are already here, minutes from Old Town, the I-35E corridor, and the neighborhoods along Round Grove Road (FM 3040).

Lewisville grew fast in the 1980s and 1990s, and a lot of that housing stock is now 30 to 40 years old. That is the age when the electrical panels of that era were never sized for today’s loads, galvanized and early-generation plumbing starts failing, and first- or second-generation HVAC systems are past due for replacement. Older homes near Old Town and Main Street (FM 1171) often need repiping and panel upgrades, while newer builds in Castle Hills and along the SH-121 corridor benefit most from duct sealing and right-sized system replacements. Whatever the vintage of your house, we have worked on one like it — probably on your street.

What Lewisville's climate does to your home

North Texas is brutal on home systems. Lewisville summers run weeks of triple-digit heat that push air conditioners to their limit, then blue-northers drop temperatures 40 degrees in an afternoon and occasional ice storms strain heating and pipes. Spring brings hail and severe storms that damage outdoor condensers and electrical service. Underneath it all, expansive clay soil swells and shrinks with the weather, shifting slab foundations and causing the slab leaks and sewer line breaks common across Denton County.
