With GENERALLUX, you pick the circuit first, then the size, then the cold. The Series AX 12,000 BTU/h is the only one on 115 V; the others need a 208-230 V circuit. Series AX and T heat down to -25 °C and Series AST down to -20 °C, according to the manufacturer’s documents. We install them in Montréal, Laval, Longueuil, the South Shore and the North Shore.
GENERALLUX puts its name on three wall lines, from the Series AX on 115 V to the Series T from 9,000 BTU/h. AirGreen looks at your circuit, the room and your winter, picks the right one with you and installs it. Each does what it does best.
The result: the right GENERALLUX, chosen with you and installed by AirGreen.
All three lines are single-zone R-410A wall units. What sets them apart: voltage, cold limit and the sizes on offer.
The only GENERALLUX on 115 V, in 12,000 BTU/h. Heats down to -25 °C according to the manufacturer.
The highest SEER among our GENERALLUX units: 23.3 at 18,000 BTU/h, per its AHRI certificate. Heats down to -20 °C.
The only line that starts at 9,000 BTU/h, for a small room. Heats down to -25 °C according to the manufacturer.
