Families taking care of families since 1912

What does over a century of service mean to the families we serve? Seider Heating, Plumbing & Electrical customers will tell you our reputation is, in one word: Rare.

Our reputation is backed every day by the customer care we provide. Whether you live in Waukesha, Milwaukee, Menomonee Falls, or Whitefish Bay—or somewhere in between—you won’t find anyone with more experience in furnace and air conditioner repair, installation, and maintenance to keep your home or business comfortable. And our expertise extends beyond heating, cooling, and air quality—to plumbing and electrical—which is why our customers say there’s simply no need to call anyone else. We’ve been taking care of families like yours since 1912—next time you need service, count on the team you know and trust.

How’s that for easy?
