Installing a new furnace is one of the most important home investments a Port Washington homeowner can make. The right system — properly sized and correctly installed — will keep your family warm through Wisconsin's coldest winters for the next 15–20 years. Burkhardt Heating, Cooling, Plumbing & Electric has been installing furnaces in Port Washington homes for over 60 years, and our NATE-certified crews bring both the technical skill and local knowledge your installation requires.
Port Washington's 1890s–1930s historic housing on Franklin Street and Van Buren Street bluffs, plus lakefront homes along the working marina and Wisconsin Avenue historic downtown present installation challenges that generic HVAC contractors may not anticipate. Bluff-top homes from the 1890s–1930s on Franklin and Van Buren Streets often carry aging steam or gravity-furnace systems that require full HVAC redesigns. Before recommending any equipment, Burkhardt performs a full heat-loss calculation on your home and evaluates your existing duct system, flue configuration, gas line capacity, and electrical service. This upfront assessment ensures your new furnace performs as designed from day one.
A historic lake michigan harbor city with a working marina, lighthouse, and distinctive bluff-top neighborhoods, Lake Michigan's lake-effect climate and salt air accelerate condenser and coil corrosion, especially on blufftop homes that face prevailing northeast winds. We install furnaces from Lennox, Carrier, Trane, and Rheem across a full range of efficiencies — from standard 80% AFUE units where venting constraints require it, to high-efficiency 96–98% AFUE two-stage and variable-speed modulating systems that cut heating bills and dramatically improve comfort. In homes without existing ductwork, we also design and install new duct systems or recommend ductless solutions.
Every Burkhardt furnace installation includes a combustion analysis at startup, a carbon monoxide safety check, a complete walkthrough of your system's operation and maintenance schedule, and our standard labor warranty. GreenSky financing with low promotional rates is available to make your new system affordable today. Call 414-206-3049 to schedule your free in-home estimate in Port Washington.
How long does a furnace installation take in a Port Washington home?
Most furnace replacements — removing the old unit, installing the new one, updating flue and gas connections, and completing startup checks — take one full business day. Installations that require new ductwork, electrical upgrades, or venting modifications may take two days. We schedule around your availability and leave your home clean when we're done.
What AFUE rating should I choose for a new furnace in Wisconsin?
For most Wisconsin homes, a high-efficiency 96% AFUE or better two-stage or variable-speed furnace pays for itself within a few years through reduced gas bills. In homes where PVC condensate venting is difficult — certain older homes with specific flue configurations — an 80% AFUE unit may be more practical. Burkhardt's comfort advisors will walk you through the options and calculate estimated payback for your specific home.
