"AC died on a Sunday in July with my newborn home. They had a tech here in 90 minutes, fixed it that afternoon, and the bill was less than I expected. These are good people."
"Got 4 quotes for a new system. Lone Star wasn't the cheapest but they actually walked me through every option. Installed it 3 days later, perfect work, no upsells."
"Been using them for 12 years now. They've fixed two ACs, replaced one, and serviced everything. Honest, on time, and they remember my dog's name. Won't use anyone else."
