Muskego's three lakes — Big Muskego Lake, Little Muskego Lake, and Lake Denoon — cover 14 percent of the city's area, and that open water shapes the local climate in both directions. In summer the lakes bring humidity; in winter, cold air masses can pool over frozen lake surfaces in January and February, extending the effective cold period beyond what neighboring inland communities experience. For the homeowners along W. Janesville Road, in the Tess Corners neighborhood, and across the city's high-homeownership residential areas, a well-maintained furnace is a winter necessity.
Muskego's housing stock reflects the city's unique development pattern. The neighborhoods that grew near Big Muskego Lake and Lake Denoon include lakefront homes converted from seasonal use, 1960s-70s ranch properties in the Durham Hill area, and newer subdivisions that expanded the city through the 1980s and 1990s. Each era brings its own furnace service profile: older homes may have been converted from oil or electric heat to gas over the years; the 1980s and 1990s homes have high-efficiency furnaces now in the repair-or-replace window.
In lakefront properties along Racine Avenue and the lake access corridors, homes that were built as summer cottages and updated to year-round residences sometimes have heating systems that weren't sized for a full Wisconsin winter — particularly where the original seasonal system was patched rather than properly replaced with equipment and ductwork designed for year-round temperature extremes.

Thermostat Issues and Diagnostics
A malfunctioning thermostat is one of the most common reasons a furnace stops working. Before assuming the worst, our technicians check thermostat calibration, wiring connections, and battery levels. We repair and install all major thermostat brands including Honeywell, Ecobee, Nest, and Emerson. If your furnace isn't turning on, is short-cycling, or won't reach the set temperature, the problem may be as simple as a thermostat replacement.
We service and install all major heating brands including Lennox, Carrier, Trane, Rheem, Goodman, American Standard, Bryant, York, Amana, Ruud, Coleman, Heil, Payne, and Tempstar. No matter what brand is in your home, our NATE-certified technicians have the training and parts to get it running.
My Muskego lakefront home was originally a seasonal cottage. The furnace struggles on the coldest days. What can be done?
Seasonal-to-year-round conversions often have furnaces sized for partial winter use that can't keep up during extreme cold. Burkhardt can perform a heat loss calculation for your home and determine whether your current equipment has the capacity for full Wisconsin winter operation or whether an upgrade is needed.
What does furnace short-cycling mean and why is it a problem in my Muskego home?
Short-cycling means the furnace runs for only a few minutes before shutting off, then restarts repeatedly. It's usually caused by an oversized furnace, a dirty filter restricting airflow, or a failing component. Short-cycling puts extreme stress on the heat exchanger and inducer motor, significantly shortening equipment life. Burkhardt can diagnose the cause and fix it.
My Muskego furnace is 18 years old and needs a repair. Is it worth fixing?
At 18 years, you're at the threshold where the repair-versus-replace analysis becomes important. If the repair is under $500 and the heat exchanger is intact, fixing it may be reasonable. For larger repairs — heat exchanger, inducer motor — replacement is often the better long-term investment. Burkhardt will give you an honest, no-pressure assessment.
