Terminal HVAC — PTAC, VTAC, water-source heat pumps and mini-splits — is maintained in volume or not at all. A program is the structure that makes volume manageable.
1. Inventory
Equipment type, model, approximate age, location and access notes for every unit. Without it, nothing downstream can be priced or verified.
2. Scope
One written per-unit scope per equipment type, including what is explicitly not included. Ambiguity here is where programs generate disputes.
3. Cycle
Annual as a baseline; semi-annual for hospitality, senior living and year-round-occupancy properties. Filter intervals are separate and shorter.
4. Access plan
Notice procedure, entry authority, sequencing, and a documented policy for units that cannot be entered. Access failures should be reported, not absorbed.
5. Documentation
Per-unit condition and performance records with photographs, rolled up into property-level findings. This is what converts maintenance into planning.
6. Review
An annual review of the deficiency list, repair spend and replacement candidates. Programs that are never reviewed drift back toward reactive within two years.
Want to know the condition of your equipment inventory?
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.
