Trusted HVAC Services in Elk River & Surrounding Areas

"I highly recommend Lake State Heating & Air. They installed our entire system—furnace, A/C, and ductwork—this past summer on our new home build, and we haven't had a single issue. It’s been a total relief having a reliable system during our first winter. Caleb is wonderful to work with and even helped explain systems we’d be looking into at the start of our home build. Thank you again for making the drive to Duluth and working above and beyond to get the job done in a timely fashion!"

This past Summer Lake State Heating & Air came up to install our furnace, A/C, ductwork, and garage furnace. Everything was installed right the first time and ran flawless our first winter in. Caleb was even nice enough to check in during the first cold snap of the winter to make sure we were staying warm. I highly recommend working with the Ellingson’s."
