One Contractor for the Mechanical Side of Your Building

Most commercial buildings end up with one company for the rooftop units, another for the drains, and a third for the annual backflow test. Cavinder holds both an Indiana HVAC license, CO19900013, and an Indiana plumbing license, PC19700254, so all of it can sit with one contractor and one phone number. Commercial operations run out of our Mishawaka office at 4027 N Home St, with Granger and South Bend covering the rest of Michiana.

Pick the side you need below, or call and describe the building. We have been doing this work here since 1999.

Planned Maintenance Beats Emergency Response

Cavinder builds commercial maintenance agreements around your specific equipment and your operating hours, not a generic residential schedule. An agreement covers the rooftop units, refrigeration, water heating and plumbing, and the annual backflow test that the water utility is going to ask for either way.

Agreement customers get priority emergency response and a documented service history, which is the part that matters when a walk-in starts losing temperature on a Saturday or a piece of equipment comes up for warranty review.

24/7 Commercial Emergency Service

A walk-in losing temperature or a rooftop unit down in July is treated as an emergency. We are open 24 hours a day, seven days a week, dispatching from Granger, Mishawaka or South Bend, whichever is closest, and there is no overtime markup on after-hours calls.

Frequently Asked Questions About Commercial Service

On the HVAC side we install, service and repair rooftop units, commercial boilers, chillers, split systems and packaged units, along with the refrigeration a commercial kitchen depends on: walk-in coolers and freezers, reach-in and prep-table units, and the condensing units that feed them. On the plumbing side we cover commercial fixtures, drain and pipe cleaning, water heating systems, backflow prevention, grease traps, bathroom renovations and water system installations.

That is the reason this side of the business exists. Cavinder holds an Indiana HVAC license, CO19900013, and an Indiana plumbing license, PC19700254, so the rooftop unit, the water heating, the backflow assembly and the kitchen drains can all sit with one contractor and one point of contact. Commercial operations run out of our Mishawaka office at 4027 N Home St.

Yes. As a licensed Indiana plumbing contractor we test, certify, repair and replace backflow prevention assemblies on commercial, irrigation and fire lines, and we file the certification the water utility requires. Most commercial devices in our area are on an annual test cycle, and we can put yours on the schedule so the deadline does not creep up on you.

Cavinder is open 24 hours a day, seven days a week, and we dispatch from whichever of our three offices is nearest to you. Most emergency calls see a technician arrive within one to three hours, faster for properties close to an office, and there is no overtime markup on after-hours work. Properties on a maintenance agreement receive priority response.

We work with restaurants, retail stores, office buildings, manufacturing and production facilities and other commercial properties across St. Joseph County, Elkhart County and Southwest Michigan, including Mishawaka, South Bend, Granger, Elkhart, Notre Dame and the surrounding communities. Cavinder has been doing this work in Michiana since 1999.
