My ceiling height is 15ft can I still install an AirLegacy?

You might be able to install it, but keep in mind that performance may be reduced and proper safety clearance could be an issue. The AirLegacy is designed to work best with ceilings around 20 feet or higher for the larger models. If your ceiling is lower, one of the smaller diameter models may be a better fit. Always be sure to follow the installation manual to maintain proper clearance and safe operation.
