Family-Owned. Community-Focused. Built to Last.

We’ve been serving the Monroe community since 1887, although our business looked much different back then!



Founded by A. Lanz & Sons, Lanz Furnace and Fireplace began as Wagons & Stoves. While our business evolved and owners changed over the years, it’s remained a family-owned business.

In 1925, we brought on the Lennox^® furnace line, which remains the major brand that we carry. And in 1998, fireplaces joined our offerings to keep your home cozier throughout the harsh winters in Monroe.

David and Carissa Kammerer bought Lanz Furnace and Fireplace in May 2010 and have brought a family feel back to the business. As time passes, one thing remains: the quality craftsmanship, workmanship and pride that was passed along the generations.

As your local Lennox Premier Dealer™, we’re committed to your total comfort and providing outstanding customer service for homeowners and businesses. That’s why 365 Day Emergency heating and cooling service is available for all brands. As our customer, your satisfaction is 100% guaranteed. Sometimes it’s a better option to replace your system. We offer free estimates on new Lennox heating and cooling systems and offer financing to qualified customers. To help keep your new system running smoothly, Lanz Furnace and Fireplace offers planned maintenance programs to save you time and money.

Besides Lennox, we also carry other trusted brands like Triangle Tube. We also proudly sell a wide range of quality fireplaces from Heat & Glo, Quadra-Fire^® and SimpliFire™, so you can find the right solution for your home.

Our family is here to keep your family comfortable. In striving to keep the legacy of the oldest heating and cooling company going in Green County, you can expect honesty, integrity and quality craftsmanship when working with Lanz Furnace and Fireplace.
