Description
Product Summary
This First Co 1.5-ton through-the-wall split system pairs the 18WCX2BA200F WCX2 Series through-the-wall condensing unit with the 19UCX05X20BV00AAF UCX Series front return air handler. The pairing is AHRI certified under reference number 217036525, rated at 16,000 BTU/h of cooling with 11.7 SEER2 and 9.6 EER2, so you get a verified match instead of guessing at compatibility.
Through-the-wall split systems are the standard setup in many condos, apartments and high-rise buildings. The slim WCX2 condenser installs in an exterior wall sleeve, and the UCX air handler mounts in a closet or recessed into an interior wall. When a building was designed around this layout, replacing both halves with a matched First Co system keeps the original openings, line sets and electrical in play and avoids costly remodeling.
The 18WCX2BA200F uses the BA cabinet (BA cabinet, 32 in tall), so measure your existing wall sleeve before ordering. The air handler includes 5 kW of factory-installed electric heat for cooler days, a multi-speed ECM blower for quiet, efficient airflow and a factory non-bleed TXV for R-454B.

Frequently Asked Questions
Is this system AHRI matched?
Yes. The 18WCX2BA condenser and 19UCX air handler are AHRI certified together under reference 217036525.
Which cabinet size do I need?
WCX2 condensers come in two cabinets. The BA cabinet is about 32 in tall by 24 in wide, and the BB cabinet is about 28 in tall by 25-3/4 in wide. Match the cabinet to your existing wall sleeve opening.
Do I need a wall panel for the air handler?
Only when the air handler is recessed into a wall. First Co's 9PWUC01L louvered wall panel covers the opening. Closet installs do not need it.
Does the system include heat?
Yes. The air handler has 5 kW of factory-installed electric heat. The condenser is cooling only.
