Navien Complete Cooling System
NAA Air Conditioner + NAM Cased Coil + NPF Hydro-Furnace
The go-to whole-home comfort system for Calgary new builds and retrofits. Three AHRI-matched components working together to deliver up to 18.0 SEER2 cooling and 97% AFUE heating — with a lifetime heat exchanger warranty.
Three Components, One Perfect System
NAA Air Conditioner (Outdoor)
Inverter-driven variable-speed cooling. Two models (NAA17V36 / NAA17V60) cover 1.5–5.0 tons. R-454B refrigerant, Gold Coat outdoor coil.
NAM Cased Coil (Indoor Bridge)
Sits on top of the NPF furnace. AHRI-matched with the NAA for maximum SEER2. Factory TXV, A2L sensor, multi-position installation.
NPF Hydro-Furnace (Indoor Heating)
97% AFUE hydronic heating. Variable capacity 15–100%. Variable-speed ECM blower maximizes combined system SEER2. Lifetime heat exchanger warranty.
Why This System Outperforms the Competition
- AHRI-certified matched ratings — efficiency numbers are verified, not marketing claims
- Up to 18.0 SEER2 on the 2-ton NAA17V36 with NAM24B and NPF
- NPF’s variable-speed ECM blower syncs with the NAA’s inverter for optimal airflow at every capacity point
- Hydronic furnace heating means gentler, quieter air distribution — the same ductwork does both jobs better
- Single Navien warranty covers all three components
- R-454B refrigerant throughout — environmentally responsible and future-proof
- Works with existing single- or two-stage conventional thermostats
- New construction or retrofit — NAM provided in standard furnace widths
