What We Do on a Roof

Complete preventive maintenance: filters, belts, blower motor, coils, drains, operating pressures, controls. Repair and replacement of units. Refurbishment of curbs and insulation at pipe penetrations.

For a fleet of multiple units, a logbook is kept for each unit: what has been done, what needs monitoring, what is nearing its end of life. This prevents emergency replacements in July.

The Most Costly Downtime

In a business, an air conditioning breakdown during a heatwave is not measured by repair cost but by hours of closure or customers leaving. This is why planned maintenance is justified over emergency repairs.

The two most frequent points of failure remain the same: a clogged coil that drives up discharge pressure, and a belt that breaks on a Friday night.

A breakdown during a heatwave is not about parts, but hours of closure

This is why planned maintenance is justified over emergency repairs. For a fleet of multiple units, a logbook for each unit prevents emergency replacements in July.

Access and Safety

Each intervention considers roof access, clearance around units, and membrane protection. Equipment is brought up via the building’s designated access or by lifting equipment, depending on the configuration.
