Locations

A-1 Services Group has technicians based across the Milwaukee metro and southeastern Wisconsin, so the one sent to you is often already nearby. Mark your request Emergency, Same Day or Next Day and dispatch schedules to match, or call 414-404-9739 for anything urgent.

For a true emergency, such as a walk in cooler losing temperature, no heat on a January morning or a gas smell, call rather than using the form so dispatch can route the closest technician right away.

Have the equipment type, model and serial number, warranty status, where the unit sits and when a technician can get in. For rooftop HVAC or condensing units, tell us how the roof is reached and whether the hatch or ladder is clear.

In winter, snow and ice on a roof can delay rooftop work, so clearing a safe path to the unit before the technician arrives saves time. The model and serial number are on the data plate, usually inside a door, on the back panel or on the unit’s side.

It can. Work outside normal hours may carry overtime rates, which is why the service request form asks you to approve overtime before the call is scheduled. You’ll know before a technician is sent.

If the repair can wait, choosing Next Day or Must Be Scheduled usually avoids overtime. When heat fails in a subzero cold snap or a cooler full of product is warming up, the overtime is often cheaper than the damage.

Often, yes. A-1 provides electrical service alongside equipment and HVAC repair, so a problem that turns out to be a failed circuit, a bad connection or an overloaded panel doesn’t need a second contractor.

That’s useful when you add new equipment, when a unit keeps tripping a breaker or when you can’t tell whether the fault is in the equipment or the building’s power. One technician can trace it from the plug back.

Yes. Multiple locations can be set up on one account, with one number to call and service history kept in one place, including work orders, spend by location and planned maintenance.

For locations beyond southeastern Wisconsin, A-1 is part of Tech24’s national service network, which supports regional and national accounts with consolidated reporting and a single point of contact.

Our Oak Creek team reviews the priority you picked, assigns a technician who covers your area and confirms timing with you. On site, the technician diagnoses the problem, whether it’s in the equipment, the HVAC or the electrical supply, then repairs, tests and documents it.

If a part isn’t on the truck, you’ll hear what’s needed and when it’s expected before the technician leaves. Including the model and serial number on your request lets us look up parts before the first visit.

Cost is based on labor time, travel, parts and any trade specific fees, such as a refrigerant reclaim fee on refrigeration and HVAC work. After hours work may carry overtime rates, which you approve on the request form before the call is scheduled.

The reclaim fee exists because federal law under Section 608 of the Clean Air Act prohibits venting refrigerant. When a sealed system is opened, the refrigerant has to be recovered with certified equipment and handled properly.

Yes, for larger repairs and projects. Your technician can give you an estimate to approve before work goes ahead, and for aging equipment or rooftop units, a repair price alongside what replacement would involve.

If replacement makes more sense, Wisconsin businesses may qualify for Focus on Energy incentives on qualifying high efficiency HVAC and kitchen equipment. Ask your technician to help you check before you buy.

A-1 Services Group typically accepts purchase orders, corporate billing and credit cards. The right option depends on your account, so let us know how your business handles vendor payments when you set up service.

Multisite accounts can usually be billed centrally, which keeps invoices for every location in one place.

A-1 Services Group is a commercial kitchen equipment, HVAC and electrical service company in Oak Creek, Wisconsin, with more than 20 years of experience. It serves restaurants, schools, stores and facilities across southeastern Wisconsin and is part of Tech24, a national foodservice equipment service network.

What sets A-1 apart is where it started. As a heating and air conditioning company first, it handles the building systems most kitchen equipment companies don’t, including rooftop HVAC, make up air and electrical service, alongside cooking equipment and refrigeration.

A-1 technicians train through Tech24 University, Tech24’s program built on a CFESA based curriculum and taught by full time trainers. Technicians who open sealed refrigerant systems must hold EPA Section 608 certification, which federal law requires.

Training continues in the field. When a technician meets an unfamiliar fault, Tech24 trainers can join by live video for a second opinion, which helps solve the problem on the first visit.

Both. A-1 is a local company based in Oak Creek, and customers regularly mention working directly with the owner. It’s also part of Tech24, which adds national training, dispatch technology and a 90-day parts and labor guarantee.

For you, that means one local number, 414-404-9739, and a team that knows southeastern Wisconsin. If you run locations beyond the region, Tech24 can coordinate service there through nearby branches and partners.
