Repair vs. Replacement: What’s Best for Your Building?

Repair is generally the right choice if the system:

Is under 12–15 years old
Has not experienced repeated issues
Has isolated component failure
Still operates efficiently

Replacement is typically recommended for:

Systems older than 15 years
Frequent repairs or major failures
High energy consumption
Equipment using outdated refrigerants (like R-22)
Units undersized or oversized for the building

PTS Mechanical will always provide honest guidance based on your system’s condition.
