Commercial HVAC Service in Milwaukee, WI
We service the chillers, boilers, rooftop units, cooling towers and building automation in Milwaukee commercial and industrial buildings, all with one team, so a fault that starts at a control point and ends at a compressor never turns into two contractors and two diagnoses.
Commercial and industrial facilities only, which means no residential side of the business competing for the truck.
A Commercial Service Company Since 2008
- In business since 2008, more than fifteen years on commercial and industrial mechanical systems.
- Commercial and industrial buildings only. We do not take residential heating and cooling work.
- Founder Jim Jensen spent more than twenty years in Carrier and York factory service before starting the company.
- Family owned, insured and bonded, with master-certified and factory-trained technicians.
Commercial HVAC Service Milwaukee Buildings Actually Need
Five service lines cover nearly every call from a metro Milwaukee facility, and the same technicians handle all five.
Chiller work is the core competence rather than a line item. We service water-cooled and air-cooled machines, including the high-tonnage centrifugal and screw chillers in downtown central plants, and a visit covers refrigerant and oil analysis, compressor and starter diagnostics, approach temperatures, condenser tube cleaning and cooling tower and pump service. Compressor overhauls and tube replacement are in scope, on Carrier, York, Trane, Quantech and JCI equipment without brand limitation.
Rooftop and packaged units carry the cooling load across Milwaukee's leased office and retail stock, and they fail on belts, bearings, contactors, economizer linkages, curbs and drains. We service
rooftop units, split and packaged systems, cooling towers, pumps and dedicated server-room cooling, and we replace equipment that has aged past the point where repair parts make sense.
Commercial Heating and Boiler Service
Milwaukee winters make the boiler the piece of equipment that cannot wait. An occupied office tower or school building that loses heat in January has hours, not days, so boiler work is where our response matters most. We service low-pressure steam and hot water boilers, condensing systems, furnaces, unit heaters, radiant heaters and make-up air units, and a call covers combustion analysis and burner tune-up, safety and limit control verification, circulator, feedwater and condensate checks, and the sequencing and outdoor reset that decide when a boiler fires. Because the same team services the controls, a heating complaint traced to a sensor or a schedule gets resolved on the same visit.
We install, program, integrate and troubleshoot building automation systems, verifying sequences, setpoints, sensor calibration and interlocks against what the equipment is actually doing rather than against what the graphic says. One contractor for the controls and the machines they sequence removes the handoff that stalls a system-wide fault.
Maintenance agreements put chillers, boilers, rooftop units, towers, pumps and controls on a visit schedule sized to the building, with documented findings after each visit that a facility manager can budget from. Most of the failures that become emergency commercial HVAC repair calls show up first as a reading on a maintenance sheet.
When something goes down between scheduled visits, an emergency call reaches a technician who can talk through the fault, not an answering service taking a message, and you get scope, timing and cost before a truck rolls.
The Milwaukee Buildings We Keep Running
Milwaukee's building stock runs from century-old steam plants to new packaged rooftop installations, and three facility types make up most of our work in the metro.
School district and campus buildings across Milwaukee run central plants and older steam systems that have to come back on schedule with students and staff in the building. We work on district chillers and boiler plants, gym and auditorium air handling, kitchen make-up air, hospital and university campus equipment, and the controls that schedule all of it around occupancy.
In a downtown or near-downtown office tower, a central plant problem reaches every leased floor at once, and in a multi-tenant retail property a single rooftop unit failure reaches tenants within the hour. We service central plants, multi-tenant rooftop equipment and the zone controls that decide which suite is comfortable, and we work around tenant hours where the building requires it.
In the plants along Milwaukee's industrial corridors, process cooling is tied to the production line, so a chiller or tower fault carries a per-hour cost. We handle process chillers, cooling towers and pumps, equipment cooling loops, and the ventilation and make-up air that keeps a shop floor within spec.

What Makes Us a Commercial HVAC Contractor Rather Than a Commercial Page
- Commercial and industrial facilities only since 2008, with chillers, boilers, rooftop units, cooling towers, pumps and building automation all in house.
- Founder Jim Jensen came out of more than twenty years in Carrier and York factory service.
- Technicians hold master certifications and factory training from major equipment manufacturers.
- Family owned, insured and bonded, run from one office in Waukesha rather than a call center.
- Emergency calls reach a technician who can talk through what the equipment is doing.
- Scope, timing and cost are stated before a truck rolls, so a repair does not become an open-ended invoice.
Office and retail properties, school and campus buildings and manufacturing plants across metro Milwaukee are on our service list, and mechanical contractors subcontract chiller work to us when a job calls for a machine to be opened.
Questions Milwaukee Facility Managers Ask First
What is the difference between commercial HVAC and residential HVAC?
The equipment is different in kind, not just in size. Commercial and industrial buildings run chillers, cooling towers, steam and hot water boiler plants, rooftop and packaged units, make-up air and a building automation system tying it all together, where a house runs a furnace and a condenser. That is why we take commercial and industrial work only, and why our technicians carry factory training on chiller and boiler platforms rather than residential equipment lines.
How is commercial HVAC service priced?
For us it starts with a site visit, because a quote written without seeing the equipment is a guess. After the visit you get scope, timing and cost in writing before work starts, whether that is a diagnostic and repair, a compressor overhaul or a maintenance agreement priced against the equipment list in the building.
Who repairs commercial chillers in the Milwaukee area?
Advanced Chiller Services works on water-cooled and air-cooled commercial chillers throughout Milwaukee County and the surrounding metro, including high-tonnage centrifugal and screw machines, on Carrier, York, Trane, Quantech and JCI equipment without brand limitation. Scopes run from refrigerant and oil analysis through compressor overhauls and condenser tube replacement. Call(414) 899-4641to schedule a site visit.
Can you handle a commercial boiler repair in Milwaukee in the middle of winter?
Yes, and it is one of the most common calls we take between November and March. We service low-pressure steam and hot water boilers, condensing systems, furnaces, unit heaters and make-up air units, and an after-hours call reaches a technician rather than an answering service.
Do you serve Mequon and the north shore?
We do. The service area runs from Milwaukee, Wauwatosa and West Allis through Glendale, Brown Deer, Whitefish Bay and Shorewood and north into Ozaukee County, including Mequon, Thiensville, Cedarburg, Grafton and Port Washington. A portfolio spread from downtown to the north shore is covered by one service company.
Metro Milwaukee, North Into Ozaukee County
Our crews are in Milwaukee County buildings every week, and the coverage runs north from there:
- Milwaukee, Wauwatosa and West Allis
- Greenfield, Oak Creek and Franklin
- Glendale, Brown Deer, Whitefish Bay and Shorewood
- Mequon, Thiensville and Cedarburg
- Grafton and Port Washington
Milwaukee is one of
ten southeastern Wisconsin counties we cover from our office at s46w32298 Highview Road in Waukesha: Waukesha, Milwaukee, Racine, Ozaukee, Walworth, Jefferson, Dane, Dodge, Columbia and Rock. A portfolio that crosses county lines gets one service company and one number instead of three contractors to coordinate.
Call About the Equipment in Your Milwaukee Building
Call (414) 899-4641 and describe what the equipment is doing. Office hours are Monday through Friday, 8am to 5pm, and emergency calls outside those hours reach a technician rather than an answering service. The first call leads to a site visit, and the site visit leads to scope, timing and cost in writing before work starts. You can also text the same number or send the details through the quote form.
