Quick Answer
What is the most common AAON repair issue in NYC?
The most common AAON calls involve belt-driven supply fan alignment and the complex internal component layouts (heat recovery wheels, economizers) that require precise mechanical maintenance. The heavy-gauge galvanized steel cabinets are durable, but the internal mechanical systems need regular attention to keep running efficiently.

Why AAON Repairs Need Brand-Specific Service
AAON is widely recognized for a real engineering approach: pioneering heavy-duty, modular commercial rooftop units with internal cabinets specifically designed to house complex components like heat recovery wheels and economizers without adding external footprint to the unit.
Norman Asbjornson founded the company in 1988 in Tulsa, Oklahoma, focused on highly efficient, modular HVAC solutions for the commercial market. AAON is a publicly traded company (NASDAQ: AAON).
What Makes The Brand Different
Durable cabinets, complex internals
AAON units have a strong reputation for durability thanks to heavy-gauge galvanized steel cabinets, but that durability doesn't extend automatically to the internal mechanical systems — belt-driven supply fans and complex component layouts (heat recovery wheels, economizers) need precise mechanical maintenance and alignment to keep performing.
The modular internal cabinet design that houses these components without external footprint is a genuine space-efficiency advantage on NYC rooftops where real estate is always at a premium.

Frequently Asked Questions
Why does my AAON unit need belt alignment so often?
AAON rooftop units commonly use belt-driven supply fans, which require precise alignment and tension to run efficiently — this is routine maintenance, not a sign of a defective unit.
What is the internal heat recovery wheel on an AAON unit?
It's a component housed within AAON's modular internal cabinet design that recovers energy from exhaust air, and it needs periodic cleaning and service to keep working efficiently.
Does AAON make residential equipment?
No — AAON is strictly a commercial and light-commercial brand.
