How much usable life does a retrofit add to an existing system?

Generally, a high-quality retrofit can add 5 to 10 years of usable life to an existing commercial system. However, this depends entirely on the structural soundness of the unit.

When do frequent repairs indicate that replacement is more cost-effective?

We use the 10% Rule: if the cost of a single repair (or the cumulative repairs over a year) exceeds 10% of the cost of a brand-new system, it’s time to stop repairing.

How do building renovations impact the choice between retrofit and replacement?

Renovations almost always tip the scales toward replacement. When you move walls, change occupancy, or add square footage, the original HVAC load calculations become obsolete. Replacement allows for right-sizing the equipment for the new space.
