Navien NAA High-Efficiency Air Conditioner
Inverter-driven variable-speed cooling with up to 18.0 SEER2 efficiency. Two outdoor units cover every Calgary home from 1.5 to 5.0 tons — using eco-friendly R-454B refrigerant.
Capacity-Matching Inverter Technology
The NAA continuously monitors your home’s comfort needs and automatically adjusts its output — speeding up or slowing down the inverter-driven compressor to match the exact load. This eliminates the inefficiency of on/off cycling found in conventional ACs.
Just two SKUs — the NAA17V36 (2–3 ton) and NAA17V60 (4–5 ton) — replace what would normally require multiple different unit sizes, simplifying inventory and installation.

Why Choose the NAA Air Conditioner?
Up to 18.0 SEER2 Efficiency
With a matched NAM cased coil and NPF Hydro-furnace, the NAA achieves up to 18.0 SEER2 — significantly reducing your summer cooling bills compared to standard single-stage units.
Wide Temperature Operation
Operates reliably in outdoor temperatures from 5°F to 124°F (-15°C to 51°C). In Calgary’s warm summers, the NAA maintains consistent cooling performance even on the hottest days.
Eco-Friendly Refrigerant
Uses R-454B, a next-generation low global warming potential (GWP) refrigerant — better for the environment without sacrificing performance.
Simple Thermostat Compatibility
No need to replace your existing thermostat. The NAA works with standard single- or two-stage conventional thermostats, making retrofits straightforward and affordable.
