HVAC and central air conditioning for guest rooms and public areas
Only category where the corpus names hotels as buyers.
The range above is an indicative planning figure taken from our own research, not a quotation and not an offer. buytogethr is pre-launch and has closed no pools.
What you are actually buying
Central cooling is bought as plant plus distribution: chillers or outdoor units, air handling and fan coil units, pumps and cooling towers where used, piping and ducting with insulation, grilles, controls and any building management integration, and ventilation for public areas. Bids vary most in their foundations. One bidder submits a heat-load calculation per space type; another applies a rule of thumb per room and quotes tonnage. They are not comparable. Indoor unit type, system architecture, guest-room noise, control strategy and where insulation, piping and electricals sit in the scope all move with it. The error that costs most is ignoring part-load behaviour: a hotel runs at partial occupancy for much of the year, and plant selected only at full load is the wrong plant.
Why hvac / central air conditioning suits collective purchasing
Ranked second for group-buy potential in the founding correspondence, and the reasoning is sound. Manufacturers are a limited set, buyers are independent properties scattered across the country, and each property installs central plant perhaps once in its life, so no owner accumulates leverage. What standardises is not the design but the schedule and the contract: approved makes, minimum efficiency thresholds, warranty length, spare-part pricing, response times and the annual maintenance rate. Each property's own heat-load calculation then sets quantities. Pooling the terms while keeping the design local is what makes this category work.
Pin down before price
- Heat-load calculation submitted per space type, with design ambient, occupancy and fresh-air assumptions stated
- Efficiency quoted at part load as well as full load, since occupancy varies through the year
- Noise limits at the unit and at the diffuser in guest rooms, and vibration isolation for plant near occupied areas
- System boundary priced line by line: ducting, insulation, piping, electricals, controls and management-system integration
- Fresh air and filtration for public areas, and the plant's behaviour when the building is half occupied
What drives ten-year cost
- Electricity is the dominant lifetime cost, and part-load efficiency decides most of it
- Annual maintenance, plus condenser tube cleaning, water treatment and refrigerant top-up on chilled-water plant
- Filter changes and coil cleaning, neglected quietly and paid for in consumption
- Compressor or chiller overhaul in the second half of life, with spare pricing agreed at purchase rather than at failure
