Compare manufacturer-published cold-weather data and warranty structures for representative systems. Keep the supplier relationship that works; trial Novair on a project where the model, documentation, and local support fit.
These are representative product families and system pairings, not a claim that every configuration is equivalent. “Capacity at 5°F,” “100% of rated capacity at 5°F,” and the lowest operating temperature describe different things. Use the matched submittal and AHRI certificate for the exact system you plan to install.
