Rooftop package units
Our Bread and Butter Since 1997
Rooftop package units cool most restaurants, retail centers, offices and warehouses in North Texas. We design, install, replace and repair them, with more than 1000 rooftops serviced. Every rooftop replacement starts with a FREE estimate and an honest repair or replace recommendation.
Repair or replace? The $5,000 rule
Multiply the unit's age by the repair quote. If the result exceeds $5,000, replacement usually makes more sense. Rooftop units commonly last about 15 to 20 years when maintained.
