Commercial HVAC Replacement in San Antonio

Every commercial HVAC system has a lifespan. Rooftop units last 15-20 years. Chillers can go 20-30 with good maintenance. When repair costs start climbing, parts become hard to find, or your system uses phased-out refrigerants like R-22, replacement is the smart financial decision. We handle full system replacements for commercial buildings across San Antonio, from single-unit swaps to complete mechanical system overhauls.

Replacement isn't just removing old equipment and dropping in new boxes. We re-evaluate load calculations, consider current building usage, and recommend right-sized equipment that meets today's efficiency standards. Oversized systems waste energy. Undersized systems can't keep up with San Antonio summers. We get the sizing right.

Frequently Asked Questions

Consider replacement when your system is 15+ years old, uses R-22 refrigerant, needs frequent repairs costing more than 50% of replacement value, or can no longer maintain comfortable temperatures.

In most cases, yes. We use temporary cooling/heating equipment and phase the work to minimize disruption.

Cost varies widely based on system type, building size, and complexity. A single 25-ton RTU replacement typically runs $15,000-$30,000 installed. Full building systems range from $150,000 to $1M+.

Modern commercial equipment is 20-40% more efficient than systems from 15-20 years ago. Most building owners see energy savings that offset a meaningful portion of the replacement cost over time.
