Delafield is Lake Country's anchor — and its homes reflect that elevated character. From century-old lakefront retreats along Nagawicka Lake and Lake Nagawicka Road to the estate developments off Cushing Park Road and the newer construction near the I-94 Lake Country interchange, Delafield's housing stock is diverse, premium, and often mechanically complex.
The conversion of seasonal lakefront cottages and summer homes to year-round residences is a recurring theme near Nagawicka Lake. Many of these properties were originally built without central air conditioning and have had systems added over the years — sometimes with equipment that wasn't properly sized for the home's square footage or the solar heat gain that comes with extensive lake-facing glazing. Delafield's large custom homes routinely exceed 3,000 square feet, and a single-zone central AC system often cannot maintain comfort across all floors and wings without proper duct design and equipment selection.
In rural Delafield properties served by private wells, iron and mineral content in the water can affect condensate drainage and cause premature corrosion in certain system components. The Bark River corridor through the city's lower elevations contributes to elevated humidity levels in summer, which increases demand on AC systems to manage both temperature and moisture simultaneously. Homes near the river see more frequent coil condensation issues and drain line mineral accumulation than properties on higher ground.

Thermostat and Controls
If your AC isn't cooling properly, the issue may be your thermostat rather than the unit itself. We diagnose and repair all thermostat types — programmable, smart (Nest, Ecobee, Honeywell), and standard models. Incorrect thermostat settings, dead batteries, faulty wiring, or a thermostat placed in direct sunlight can all cause cooling problems. We'll pinpoint the issue and get your system running right.
My Delafield lakefront home was converted from seasonal use. The AC barely keeps up in summer — what's wrong?
Seasonal-to-year-round conversions often have undersized AC equipment or ductwork that was added without a proper load calculation. Sun exposure on lake-facing sides also increases heat gain significantly. Burkhardt can assess your current system, perform a Manual J load calculation, and recommend right-sized equipment or zoning upgrades to solve the problem.
