The NAA Series delivers reliable, high-efficiency air conditioning using inverter-driven, variable-capacity technology designed to match real-world cooling demand. Instead of cycling on and off at full power, NAA continuously adjusts output in small, precise increments to maintain comfort more efficiently and quietly.
Built for homeowners who want modern performance without added system complexity, the NAA Series offers a balanced approach to efficiency, comfort, and value, making the NAA a perfect fit for a wide range of residential and light commercial applications.
Unlike traditional single-stage air conditioners that run full blast or not at all, the NAA Series uses inverter-driven technology to operate across a wide range of capacities - it’s like having a dimmer switch instead of an on/off switch. Each NAA AC unit covers a range of cooling output, rather than a single fixed tonnage.
This approach allows the cooling system to run longer at lower speeds, minimizing energy consumption while providing closer temperature and humidity control, and improving overall comfort.
The NAA Series is engineered to simplify system design and installation while delivering
dependable, high-efficiency air conditioning comfort.
With NAA, contractors have fewer models to manage and more flexibility in system design. Homeowners benefit from smoother operation, lower noise levels, and consistent comfort throughout the cooling season.
Deliver rated performance and long-term reliability, when matched as a system, NAA provides dependable efficiency across a wide range of climates and installation conditions.
Our NAA Series AC is designed to be paired with our NAM cased coils, NPF Hydro-furnaces, and select NAS air handlers.

The NAA Series uses inverter-driven, variable-capacity technology that allows the system to continuously adjust output instead of cycling on and off at full capacity. This results in steadier comfort, improved efficiency, and quieter operation compared to traditional single-stage systems.
Each NAA outdoor unit is designed to operate across a range of cooling capacities when paired with matched indoor equipment. This flexibility simplifies model selection and allows the system to better match real-world cooling demand, improving comfort and efficiency.
Yes, the NAA series can be configured to match specific climate requirements by being able to fine tune both capacity and airflow independently.
