A three-hundred-room hotel does not have an HVAC system in the guest rooms. It has three hundred of them: a PTAC, VTAC, water-source heat pump or mini-split in every room, each with its own filter, coil, blower, drainage path and controls, each aging at a slightly different rate.
Most properties manage that inventory reactively — engineering responds when the front desk calls. A preventive program replaces the call with a schedule.
Start from an inventory, not a work order
The first step is knowing what is actually installed. Equipment type, model, approximate age and location for every room. Properties that have been through renovations frequently have three or four generations of equipment in the building, and each behaves differently.
That inventory is what turns 'clean the AC units' into a scope you can price, schedule and verify.
Define one repeatable per-unit scope
Every unit should get the same defined work: filter service, coil cleaning, blower cleaning, drain pan and condensate service, operational test, temperature performance readings, noise assessment and a condition inspection.
Consistency matters more than heroics on any single unit. If the scope varies room to room, the resulting data is not comparable and the program cannot be managed.
Schedule against occupancy
Work is planned by floor and room block against the occupancy forecast, so rooms leave inventory in planned batches during softer periods rather than unpredictably during peak demand.
Shoulder seasons are the natural windows: ahead of summer cooling load and ahead of the heating season.
Report at two levels
Engineering needs unit-level detail — what was found in room 812. Ownership and the general manager need property-level findings: how much of the inventory is in good condition, where the deficiencies cluster, and what should be budgeted.
A program that produces only a completed invoice produces no decisions.
Where to begin
Most properties start with a condition assessment across a representative sample of rooms. It establishes the real state of the inventory and sizes the maintenance program honestly, instead of committing the property to a scope nobody has validated.

A-TAC maintains PTAC, VTAC, water-source heat pump and mini-split systems across the NYC metro area — New York City, nearby New Jersey, Westchester and Long Island. We can assess a representative sample of units or the full inventory and report what we find.
