ABOUT A-1 Services Group

Built On Heating And Air, Grown Into The Whole Kitchen

A-1 Services Group started as a heating and air conditioning company, and more than 20 years later that’s still where its roots are. Over time, customers asked the same technicians who kept their rooftop units running to look at the walk in, the fryer and the electrical panel feeding them, and A-1 grew into a full commercial kitchen service company. Today our office is at 7373 South 6th Street in Oak Creek, and our technicians work across the Milwaukee metro and out to Racine, Kenosha and Waukesha.

That history is why A-1 looks at a kitchen as one system. A cooler that struggles in July may have a condenser problem or a rooftop unit problem. A fryer pilot that won’t stay lit may be a make up air problem. A unit that keeps tripping may be an electrical problem. One A-1 technician can follow the fault across all of them instead of handing you off to three contractors.

As a Tech24 company, A-1 pairs that local, owner involved service with national resources: technician training through Tech24 University, dispatch technology and a 90-day parts and labor guarantee on repairs.

FAQS

Questions About A-1

Who is A-1 Services Group?

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.

What training and certifications do A-1 technicians have?

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.

Is A-1 Services Group a local company or part of a national chain?

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.
