Contact A-1 Services Group

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.
