Greenfield is an inner-ring southwest suburb with compact 1950s–1960s ranch homes near Southridge Mall and quieter residential pockets near Whitnall Park and Root River Parkway. For Milwaukee County homeowners who need flexible heating and cooling without extending existing ductwork, a ductless mini split is one of the smartest comfort investments available — and Burkhardt Heating, Cooling, Plumbing & Electric has been installing them across the Milwaukee metro for decades.
As a Mitsubishi Diamond Contractor — the manufacturer's highest dealer designation — Burkhardt holds factory-level certification on the full Mitsubishi Electric lineup, including the Hyper-Heating INVERTER series designed specifically for Wisconsin's climate.
Why Ductless Works in Greenfield
The postwar ranch homes and compact bungalows that define much of Greenfield's residential character were built in an era before central air conditioning was standard. Many have limited or no ductwork, making forced-air system extensions impractical without significant renovation. A ductless mini split solves this with a single small wall penetration connecting an outdoor compressor to one or more slim indoor air handlers — no dropped ceilings, no months of construction disruption. 1950s Greenfield ranch homes often lack ductwork in bedroom wings — ductless systems solve comfort issues without wall demolition.
Built for Wisconsin Winters
Standard heat pumps lose capacity when temperatures fall below freezing — not acceptable in southeastern Wisconsin, where January lows routinely hit single digits. Mitsubishi's Hyper-Heating technology delivers full rated output down to 5°F and continues operating to -13°F, making it viable as a primary heat source through Milwaukee County's coldest nights.
Zone Control and Energy Savings
Ductless systems condition individual rooms independently. You stop paying to heat or cool empty spaces, every family member controls their own comfort zone, and Mitsubishi SEER ratings above 20 mean real savings on utility bills across long Wisconsin heating and cooling seasons. Common applications in Greenfield include sunrooms, finished basements without ductwork, home offices, and upper-level rooms that run warmer than the rest of the house.

How long does a ductless mini split installation take in Greenfield?
A single-zone installation in a Greenfield home typically takes four to six hours. Multi-zone systems with two to four indoor air handlers usually require one full day. Our crews arrive prepared with all materials and handle the complete installation including electrical connections and startup commissioning.
Can a Mitsubishi mini split handle Greenfield's winters as a primary heat source?
Yes. Mitsubishi's Hyper-Heating INVERTER series maintains full capacity down to 5°F and operates as low as -13°F — fully capable of handling Milwaukee County's coldest stretches. Many Greenfield homeowners use a mini split as their primary heat source in additions and bonus rooms, or as a supplement that reduces the load on an aging furnace.
