FAQ

Commercial Air Conditioning — frequently asked

VRF or chilled-water for a mid-size commercial building?

Below ~500 kW total load and where fan-coil / cassette terminals are acceptable, VRF wins on install cost, footprint and simultaneous heat recovery. Above 500 kW, a chilled-water plant with AHUs typically wins on lifecycle cost and hygienic requirements.

Which low-GWP refrigerant should I specify?

For small splits and VRF: R32 (GWP 675) and R454B (GWP 466) are the current default. For larger chillers: R1234ze, R513A or R290 (propane) depending on capacity and safety zoning.

How do I ensure BMS integration and metering?

Specify BACnet/IP or Modbus TCP from the OEM, embedded kWh metering per system, and open APIs for remote monitoring — ColdMatch specs this into every RFQ.

How fast can ColdMatch source commercial AC?

48 hours to shortlist installers and OEMs, 1–3 weeks for standard packages, 4–6 weeks for large chilled-water plants.
