Commercial HVAC & Mechanical Contractors in Green Bay, WI.

HVAC Installation

Green Bay plants and commercial buildings 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 facilities, and our EPA 608 certified technicians handle refrigerant safely and to code.

Replacements often happen while a facility keeps running, so we sequence the work around daily operations, the same way our electrical crews are phasing work through the Waukesha County Courthouse renovation elsewhere in Wisconsin. Because we also self-perform electrical work, equipment and power are planned together under one contract. See our commercial HVAC installation services.

Industrial Ventilation

Paper mills and production facilities need air that moves with the process. Our HVAC contractors install process ventilation for Green Bay mills and plants, along with general ventilation and indoor air quality (IAQ) improvements, including filtration upgrades, so the air moving through a facility is as well planned as the equipment moving it. Fans, controls, and power for those systems come from the same company, so ventilation and electrical scopes are coordinated from the start.

Budgeting for an HVAC Replacement

A realistic HVAC budget covers more than the equipment itself. Removal of the old unit, curbs or adapters for new rooftop equipment, electrical work to feed the new unit, controls, and startup all belong in the number. Green Bay owners planning a replacement should also allow for equipment lead times and schedule the work outside the peak heating season, so the project isn't priced or rushed under pressure. One contract for the mechanical and electrical scope keeps those pieces in a single estimate.

Planning Around the Heating Season

Green Bay facilities lean hard on their heating equipment for much of the year, which makes the timing of boiler and rooftop unit replacements important. Heating work is safest to schedule before cold weather arrives, and cooling equipment before summer demand. When aging equipment is nearing the end of its life, planning the replacement a season ahead leaves time for equipment lead times and the electrical and controls work that goes with it, rather than forcing a rushed decision after a failure. Before requesting a quote, gather the make, model, and age of existing units along with recent service records.

HVAC in Industrial Environments

Mechanical systems in mills and production facilities face conditions most office equipment never sees. Airborne dust and fibers load filters and coils quickly, process heat changes how a space needs to be ventilated, and make-up air has to replace what exhaust systems remove. Before a replacement or upgrade, document the processes in each area, the current exhaust and ventilation equipment, known problem spots, and which areas cannot lose ventilation during production. Sharing that information before pricing lets the estimator plan equipment, ductwork, power, and controls as one coordinated scope. A regular maintenance schedule matters even more here, since filters, belts, and dampers wear faster under industrial conditions.

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.
