Low-temperature operation and heating capacity
Select Novair models are described as rated for heating operation down to −31°F (−35°C). The operating limit does not mean full rated capacity at that temperature. Use the selected model’s published performance tables to assess the project.
A winter equipment review
- Compare the calculated building heating load with capacity at the local winter design temperature.
- Review defrost behavior, base pan heating, mounting requirements, and snow clearance in the installation manual.
- Confirm the indoor and outdoor match, electrical requirements, and any planned supplemental heat.
- Check the exact model’s efficiency and certification documents before making eligibility or performance claims.
Ask for the model documents
Send the proposed outdoor and indoor model numbers to our team. Request the relevant submittal, installation manual, and low-temperature performance information before finalizing an order. Our technical documents page explains what to request.
