Welcome to Kingsley Mercantile Plumbing and Heating! 
We are so thrilled to be running a business in the town of Harmony.  We both grew up in the area and and love calling it home!

Before owning the store Kerry was a letter carrier in Rochester MN and Jane ran a daycare on their farm near Harmony. We have four children and 15 grandchildren and we adore them all!  It is not uncommon to see a little one around the store helping out! We love being able to work together every day and so enjoy all the friendly people who cross our paths!

We feel very blessed to work with a tremendous set of individuals at the Mercantile who make coming to work every day awesome!  We know our employees are the backbone of our business and appreciate each of them so greatly!

As of October 1, 2025, Kingsley Mercantile divided into two businesses. Kingsley Mercantile Plumbing and Heating and Harmony Mercantile.

Kerry and Jane Kingsley will continue to operate the Plumbing and Heating services as they always have. This includes plumbing, heating and cooling, appliance repair and refrigeration.
The phone number and mailing address will remain the same, but the physical location will now be located behind the hardware store at 20 Center St. E. in Harmony.

Andrew and Lisa Kingsley have taken over the hardware store and Speed Queen dealership. The business is now Harmony Mercantile and the location will remain the same. They will be expanding the current offerings to include toys, a kitchen store and more.

If we can already claim you as a customer…we couldn’t tell you how much we appreciate your patronage!  If you have never visited our store we would love to have you stop in for a chat and be able to share with you what we are all about!
