Your local team in Gainesville

As the Cooke County seat and the last Texas stop on I-35 before the Red River, Gainesville anchors our northern service area — courthouse-square-era homes downtown, ranch properties out toward the county line. As the Cooke County seat and a nationally recognized Medal of Honor Host City, Gainesville has one of the oldest housing stocks we service. The Victorian and Craftsman homes around the courthouse square and the ranch houses built through the mid-1900s bring a familiar set of problems: 60-amp panels and fuse boxes that can't handle modern loads, galvanized supply lines and cast-iron drains reaching the end of their life, and aging ductwork that leaks conditioned air into attics.

Graco Heating & Air has served North Texas for more than 30 years, and we treat Gainesville — along with Lindsay, Callisburg, Valley View, and the Lake Kiowa and Moss Lake communities — as part of our regular territory. Whether you need a panel upgrade in a historic home near downtown or a full system replacement out toward Moss Lake, we show up with flat-rate pricing and back our installs with a 2-year labor warranty.

What Gainesville's climate does to your home

Winter bites harder at the Red River than in the metro — Gainesville regularly runs several degrees colder than Dallas, and ice storms that graze the metroplex land square here, taking down power and freezing pipes. Summer is the same long grind as the rest of North Texas, and spring storms cross open Cooke County ranchland with their hail intact. Older downtown homes add aging wiring and original plumbing to the workload.

Gainesville questions, answered

How fast can you reach Gainesville from your Lewisville office?

We're about 45 minutes up I-35 from our shop at 985 East Highway 121 in Lewisville, and we route technicians through Cooke County regularly. For no-heat, no-cool, or active leak emergencies, we offer 24/7 service, so you're never waiting until Monday morning.

Do you serve Lake Kiowa and the rural areas around Gainesville?

Yes. We serve Lake Kiowa, Moss Lake, Lindsay, Callisburg, Valley View, and the surrounding Cooke County countryside. Rural properties on wells and propane are no problem — our technicians work on them every week.

My Gainesville home still has its original electrical panel. Should I upgrade?

If your home has a fuse box or a 60- or 100-amp panel, it likely can't safely support modern HVAC equipment, kitchen appliances, and EV charging. Many of Gainesville's pre-1980 homes are due for a panel upgrade, and we can inspect yours and quote a flat-rate price before any work begins.

What does an HVAC service call cost in Gainesville?

We use flat-rate pricing, so you approve the exact price before we start — no hourly surprises. Installs come with a 2-year labor warranty, and we offer military and first responder discounts. Call (817) 725-9234 for a quote or to schedule a visit.
