Why Mini-Splits?
Ductless Comfort for Any Chicago Home
Mini-split heat pumps deliver efficient heating and cooling without ductwork — perfect for additions, sunrooms, garages, and older Chicago homes. D's Air installs the full Lennox single-zone lineup: the MWLD cold-climate series for Chicago winters, the MWPD standard series for year-round comfort, and the MWHD budget series for cost-conscious homeowners. All units use R-32 refrigerant and DC inverter technology for quiet, efficient operation.
MWLD — Cold Climate Series
Built for Chicago winters. Heats down to -13°F.
The MWLD is Lennox's cold-climate single-zone mini-split — engineered for Chicago's harsh winters. Variable frequency rotary compressor with DC inverter technology delivers reliable heating even when temperatures drop well below zero. R-32 refrigerant for lower global warming potential.
Variable Frequency Rotary Compressor · DC Inverter · R-32 · 208/230-1-60
Best for: Primary heating zones, additions, rooms that need reliable heat in extreme cold.
