Furnace Installation in Oconomowoc, WI

A Wisconsin winter puts every furnace to the test. Burkhardt Heating, Cooling, Plumbing & Electric has installed heating systems across Waukesha County for over 60 years. Our NATE-certified technicians take a methodical approach to every new furnace installation in Oconomowoc — starting with an accurate load calculation and ending with a system that delivers even, efficient heat.

**High-Efficiency Gas Furnaces**

Today's condensing furnaces achieve AFUE ratings of 96–98%, meaning nearly all of the gas you pay for becomes heat in your home — compared to 70–80% for furnaces installed before the 1990s. Burkhardt installs systems from Lennox, Carrier, Trane, Goodman, Rheem, and American Standard. Many feature variable-speed blower motors and two-stage or modulating burners for consistent temperatures and quieter operation.

**Proper Sizing for Oconomowoc Homes**

Given Oconomowoc's string of glacial lakes and lakefront properties dating back to the Gilded Age, alongside newer subdivision growth near I-94, homes here vary in size, layout, and insulation quality. An oversized furnace short-cycles — blasting heat in short bursts that stress the heat exchanger and waste fuel. Our technicians perform a Manual J load calculation before recommending any equipment, matching the furnace to your specific home.

**Ductwork Assessment**

A new furnace is only as effective as the ductwork distributing its heat. We inspect existing ducts for leaks, undersized runs, and damaged sections before or during installation. Sealing leaky ducts adds another 15–25% efficiency gain on top of the new equipment's performance.

**Rebates and Financing**

Wisconsin Focus on Energy rebates apply to qualifying high-efficiency furnace installations. Burkhardt offers GreenSky financing so Oconomowoc homeowners can select the right system without compromise.

**Frequently Asked Questions**

**How long does furnace installation take in Oconomowoc?** A standard furnace installation typically takes four to six hours. Work involving ductwork modifications or new gas line connections may require a full day. We provide a time estimate before any work begins.

**What AFUE rating should I choose for my Oconomowoc home?** Given Wisconsin's long heating season, we recommend 96% AFUE or higher for most Oconomowoc homes. The energy savings typically recover the modest price premium within a few years. Our technicians walk through the payback calculation during your consultation.
