Why Us, Here

Why Marathon County Homeowners Call Us

We run Marathon County every working day — it's where the volume is, and a big reason our vans stay stocked the way they do. From emergency furnace calls in Weston to full Bryant system installations on new Kronenwetter builds, the county gets the same standard Merrill does: real callbacks, honest quotes, and installations our own crews stand behind.

If you're near Rib Mountain, the Eau Claire Dells, or Nine Mile Forest — you're in our normal territory. Your Marathon County project is handled by our own crew: equipment, venting, controls, and the permits pulled for you.

“My furnace went out and I called them at 8pm. The service tech (Tyler) came out to try and get it up and running again… He ran me through my options for my almost 30 year old furnace and was straight forward and honest with me… Both Mitch and Tyler offered to loan me space heaters to keep my family warm… They’re honest, straight forward, and very professional. I WILL be recommending them every chance I get!”

“We called to get an estimate on getting a whole home humidifier install and they were able to have someone come out the next day… Installation went great and the guys let us know what they were doing the whole time and cleaned up after themselves. They went above and beyond and provided great customer service from our first phone call, through the process, and a follow up phone call after the work was complete.”

“Outstanding service, 3 person crew was professional and polite. Crew was thorough and not afraid to answer any questions. Once our central air conditioner was installed and operational they were great with explaining our new thermostat and functions of it and the unit.”
