Aspen Manufacturing is one of the largest independent builders of evaporator coils and air handlers in North America, and their equipment matches up with virtually every major condenser and heat pump brand. This category covers Aspen, AspenPRO, and Airmark equipment along with the OEM parts that keep it running: cased and uncased evaporator coils, multi-position and wall-mount air handlers, drain and condensate pans, thermal expansion valves, blower motors and control boards, electric heat kits, and upflow-to-downflow conversion kits. It also covers the A2L refrigerant detection sensor kits now required as the industry transitions to R-454B — parts that are in sharp demand and frequently backordered elsewhere. NorthStock holds real inventory on these lines. Shipping is fast and free on standard orders, expedited options are available, and when a coil fails mid-season and the local branch is three weeks out, we can put one on a truck now.
