Your Local, Repair-First HVAC Team in Denton, TX
Serving Denton and northern Denton County — including Robson Ranch, Corinth, and Southridge — with honest diagnostics, flat-rate repairs, and reliable residential and light commercial HVAC service.
In Denton, summer attic temperatures routinely exceed 135°F–145°F while winter cold fronts test gas furnaces and heat pump defrost boards overnight. That extreme thermal swing exposes weak run capacitors, pitted contactors, restricted evaporator coils, and leaking refrigerant lines fast.
Our philosophy in Denton is simple: Maintain first, repair second, replace last. We diagnose your system completely free ($0 diagnostic fee) and present clear, flat-rate repair options before touching a tool.

What Texas Homeowners Say About SunDollar
Homeowners in Denton and across Denton County trust us for honest diagnostics, zero sales games, and dependable craftsmanship.
“Another company told us our compressor was dead and quoted $11,500 for a whole new system. SunDollar came out for a free second opinion, found a failed dual capacitor and burnt wire, and had our AC blowing ice cold in 40 minutes for a fraction of the cost!”
“Refreshing to work with an HVAC company that actually publishes their prices online and doesn't charge a trip fee just to walk through the door. Fast same-day dispatch, spotless work, and super respectful technician.”
“We signed up for the $19.85/month maintenance agreement because our home has two AC units and every other company wanted $45/month for two systems. They tuned up both units thoroughly and never tried to upsell us.”
