Rooftop package unit repair
Light commercial, same physics, harder access.
We diagnose RTUs with gauges and a meter, not with “it’s old, replace the curb.”
Light commercial rooftop and VRF jobs fail on the same physics as homes, plus access, hours, and zoning.
Use this as a field guide to rooftop package unit repair, then book a visit if the house still misbehaves.
We service rooftop packages, VRF, and commercial refrigeration (coolers, freezers, ice machines) with the same diagnose-first rule.
We map rooftop package unit repair to the actual failed part or design limit. Age of the system is a data point, not the diagnosis.
You approve any repair after the findings are written down. Diagnostic visits are a flat $69. New installation estimates are free in-home with a load calculation — not a number invented from square footage on Zillow.
A restaurant rooftop quoted like a bedroom mini-split will miss clearances, drains, and after-hours constraints.
A company that skips testing on rooftop package unit repair will skip it on the next call too. We would rather lose a job than install the wrong thing.
