Oak Mountain Air installs right-sized, high-efficiency HVAC systems across greater Birmingham — designed with real load calculations, not rules of thumb.
Oversized equipment is the most common mistake in residential HVAC — it short-cycles, leaves rooms humid, wears out early, and costs more to run. We start with the math instead of a guess.
A full Manual J on your actual home — construction, orientation, windows, insulation, and infiltration — so the system matches the building, not a square-footage shortcut.
Right-sizing means steadier temperatures room to room, real humidity control through Alabama summers, quieter operation, and lower monthly bills.
Modern variable-speed inverter equipment, brazed and evacuated properly, charged to target, and commissioned so it performs the way it was designed to.
Complete design and installation for new construction and additions — the right equipment, ductwork, and controls, engineered around your home.

Oak Mountain Air was founded by Lee, a licensed mechanical engineer, to bring the discipline of engineering design to something most homeowners never see done carefully: the sizing and installation of their heating and cooling system.
Through his engineering practice, Steel City Engineering, Lee has spent years on the math and mechanics of how buildings move heat and air. Oak Mountain Air applies that same standard to your home — proper load calculations, clean installations, and honest recommendations, whether that means a full replacement or simply a tune-up.
