Commercial HVAC & Mechanical Contractors in Eau Claire, WI.

HVAC Installation

Eau Claire owners and general contractors looking for commercial HVAC get in-house crews. We install and replace rooftop units (RTUs), chillers, boilers, VRF and split systems, and ventilation for new construction and existing buildings, and our EPA 608 certified technicians handle refrigerant safely and to code.

Replacements often happen while a building stays open, so we sequence the work around daily operations. As a mechanical contractor that also self-performs electrical work, we plan equipment and power together under one contract. See our commercial HVAC installation services.

Healthcare & Campus Facilities

Healthcare facilities and university and school campuses can't shut down for an HVAC project. Our HVAC contractors install heating, cooling, and ventilation for clinics, classrooms, and campus buildings, including indoor air quality (IAQ) improvements and filtration upgrades, and we schedule the work around patient care and the academic calendar.

Elsewhere in Wisconsin, our electrical crews are phasing work through the occupied Waukesha County Courthouse renovation. See our projects.

Before You Request HVAC Pricing

Good HVAC pricing starts with an honest picture of what's there today. Gather equipment nameplate information, the age of rooftop units, boilers, and chillers, recent service reports, and notes on rooms that run too warm, too cold, or stuffy. For clinics and classrooms, list any spaces with special ventilation or filtration needs. Share access details as well. Roof hatches, mechanical room doors, and staging areas all affect how old equipment comes out and new equipment goes in. If the work is part of a larger renovation, include the overall construction schedule. Because we self-perform electrical work, we also review the power feeding each unit so replacements are planned with the right electrical connections.

Planning Around Western Wisconsin Seasons

In western Wisconsin, heating equipment carries a building through long winters, so boiler and heating replacements are best completed before cold weather sets in, and cooling work before summer. Larger mechanical equipment can carry long lead times, which makes early decisions important, and deciding early also leaves time to coordinate equipment setting, shutdowns, and the electrical connections new units need. On campuses, summer and semester breaks often provide the best windows; in clinics, phasing keeps occupied areas comfortable while work moves through the building.

Once new equipment is running, a regular maintenance schedule protects the investment from its first season on and keeps a record of how each unit performs over time. That history gives facility teams a clear view of equipment condition when it's time to plan next year's budget.

Repair or Replace?

When older equipment starts failing, the choice between another repair and a replacement comes down to age, repair history, and what the building needs next. Frequent breakdowns, rising energy bills, and parts that are hard to find are common signs a unit is near the end of its life. Our technicians can assess existing equipment on a service visit and lay out both options, so Eau Claire owners can plan the spend instead of reacting to the next failure.

Planned Maintenance

Our work doesn't end at closeout. Planned maintenance agreements put RTUs, chillers, boilers, VRF systems, and ventilation on a regular service schedule, helping equipment run efficiently, last longer, and show problems before they turn into failures.
