Commercial heating and cooling repair across Grand Rapids
A dead rooftop unit costs a restaurant a dinner service and a shop its afternoon. We answer any hour and work to get the space back to temperature before the next opening.
The short answer
Commercial HVAC repair in Grand Rapids usually starts on the roof: a packaged unit with a failed compressor contactor, a slipped belt, a tripped high-pressure switch or a gas section that will not light. We diagnose on the first visit, make the repair when the part is common, and keep the building running on remaining units while a special part comes in.
What you might notice
Signs a commercial unit is about to fail
Screeching or slapping
A worn or loose blower belt.
Water in the ceiling
A clogged condensate drain or pan.
Hot and cold spots
Failed dampers, a weak stage or airflow problems.
Tripped breakers
A motor or compressor drawing too much current.
Keep the doors open
What breaks on commercial equipment
Commercial units run longer hours than any house furnace, often with economizers, multiple stages and building controls layered on top. Most failures are wear parts: belts, contactors, capacitors, igniters and condenser fan motors. The difference is the stakes, because a closed dining room or a warm server closet costs money by the hour.
If the equipment is past saving, our commercial HVAC installation page covers replacement. For keeping repairs rare, see rooftop unit service in Grand Rapids.
The calls we get most
Rooftop unit failures
Packaged rooftop units combine the compressor, condenser, gas heat and blower in one cabinet, so one call can mean any of them. Common failures include a broken or slipped blower belt, a burned contactor, a failed condenser fan motor, a clogged condensate drain that trips the float switch, and gas ignition faults in winter. We check the unit's own fault codes and the building thermostat or controller, then work through power, airflow and refrigerant in order so the fix addresses the cause and not only the symptom.
Restaurant and retail cooling loss
Kitchens and busy stores carry heavy cooling loads from cooking equipment, lighting and people, so a unit that was barely keeping up fails first on a hot Saturday. Dirty condenser coils, grease-loaded filters near a kitchen and undercharged refrigerant are frequent culprits. When a make-up air unit is part of the picture, a building that goes negative pulls hot outside air in through every door. We look at the whole system rather than the one unit that tripped. Related work is on our make-up air page.
Office no-heat calls
A cold office on a Monday morning usually traces to a gas section that failed to light over the weekend: a bad inducer motor, a pressure switch, a flame sensor or an igniter. Some buildings have a unit heater or split furnace serving one area, and those fail the same ways a home furnace does. We restore heat, test the heat exchanger and flue on gas units, and flag any unit whose age or condition makes a repeat failure likely before the coldest weeks arrive.
From the call to a working system
How a commercial repair call runs
Call and triage
We ask what the space is doing and whether other units are running.
On-site diagnosis
Fault codes, controls, power, airflow and refrigerant checked in order.
Approve the fix
You get the price and any part lead time before work starts.
Repair and verify
Unit restarted and run through heating or cooling stages.
Written notes
What failed, why, and anything else on the unit worth budgeting for.
Timing
How long the space will be affected
Most rooftop repairs involving belts, contactors, capacitors, igniters or drains are finished on the first visit, usually within a couple of hours of arrival. Motor and control board replacements depend on whether the part is available locally.
Compressor and heat exchanger failures are major repairs, and we lay out repair against replacement before the building commits to either.
Local conditions
Short heat waves and busy corridors
Grand Rapids averages only about ten days a year at 90 degrees or above, so a rooftop unit that has been limping along often gets through June and then gives out on the first truly hot afternoon. Kentwood, on M-6 and I-96, is roughly half single-family homes, with large apartment buildings and attached rows making up much of the rest, and buildings like those run on packaged or split equipment that needs the same attention before summer.

Pricing, explained
What a commercial repair costs depends on
Commercial repairs are priced after diagnosis, part by part, and we tell you before starting if a part has a lead time.
The failed part
A belt or contactor is quick; a compressor or heat exchanger is a major repair.
Unit size and type
Larger tonnage and multi-stage equipment take longer to diagnose.
Roof access
Roof hatches, ladders and fall protection affect time on site.
After-hours timing
Night and weekend calls cost more than scheduled weekday work.
Parts lead time
Brand-specific control boards may need to be ordered in.
