G's Heating and Cooling LLC handles commercial refrigeration repair and maintenance for restaurants, stores, and other businesses in Detroit, MI, including walk-in coolers, walk-in freezers, and the refrigeration equipment that keeps product cold. If your unit is running warm, icing up, or cycling oddly, call or send a request and we will talk through what you are seeing and set up a visit.

Most refrigeration trouble starts small. The walk-in takes longer to recover after a delivery, the compressor runs more than it used to, or there is a puddle near the door that was not there last week. Then a hot Friday rush arrives and the box cannot keep up. Catching the pattern early is cheaper than throwing out a full cooler of inventory, and it is easier on your schedule too.

Warning signs to watch

Refrigeration equipment usually tells you something is wrong before it quits. Walk-ins and freezers fail in different ways, so it helps to know what each one looks like.

Walk-in coolers

Box temperature creeping up during busy service or after deliveries
Water pooling on the floor or dripping from the evaporator area
Door gaskets that are torn, flattened, or no longer seal
Fans that are noisy, slow, or not moving air
A compressor that runs almost nonstop

Walk-in freezers

Heavy frost or ice buildup on the evaporator coil or around the door
Frozen product that feels soft on one shelf and rock solid on another
Ice forming on the floor near the drain or threshold
Defrost cycles that seem too long, too short, or never end

If you notice any of these, write down the box temperature and when it happened. That detail helps narrow down the cause quickly.

What we work on

Our commercial refrigeration work covers the equipment food businesses rely on every day:

Walk-in cooler repair
Walk-in freezer repair
Refrigeration repairs for units that are warm, icing, leaking, or short cycling
Routine refrigeration maintenance to catch wear before it turns into a failure

We serve restaurants, stores, and other businesses that store perishable product, so we are used to working around open hours, deliveries, and tight back-of-house space.

Repair or maintenance?

These two get mixed up often. Repair is what you need when something has already gone wrong: the box will not hold temperature, a fan has died, or a coil is frozen solid. Maintenance is scheduled attention to a unit that is still running, so worn parts and buildup get found before they cost you product.

This page covers both. Building a new walk-in from scratch or replacing a complete system is a different kind of project, so if that is on your mind, ask us and we can discuss what makes sense. Comfort heating and air conditioning for the dining room or sales floor is also handled separately from refrigeration.

How visits work

Every building is different, but a refrigeration visit generally follows a familiar order.

Conversation first. You describe the symptoms, how long they have been happening, and what product is at risk.
Inspection. The technician checks box temperature, door seals, fans, coils, drainage, and the condensing equipment to see where the problem starts.
Diagnosis. You hear what was found, what is causing it, and which parts of the system are involved.
Options and approval. Repair choices are laid out before work begins, so nothing surprising shows up later.
Repair and testing. After the fix, the unit is run and temperatures are checked to confirm it is pulling down and holding.

Detroit conditions that stress equipment

Metro Detroit summers are typically warm and humid, and that is when condensing units work hardest. Kitchens add their own heat, grease, and airborne dust, which can clog coils and slow airflow. Older buildings may also have tight mechanical spaces or limited ventilation around equipment, and that can push temperatures up further.

Winter has its own quirks, since cold air coming in at loading doors can affect how a system behaves. We work with businesses across Detroit and nearby areas, including Troy, Royal Oak, Birmingham, Lake Orient, and Blooming Hill.

What good work looks like

Whoever you hire, a few standards tell you whether the job was done right:

The technician looks for the cause, not just the symptom, and can explain it in plain language.
Temperatures are verified after the repair, not assumed.
Coils, drains, and door seals get a look even when they were not the original complaint.
Work is scheduled around your service hours and deliveries when possible.
The area is left clean, and you get a clear summary of what was done and what to watch next.

What affects the cost

Refrigeration pricing depends on the situation, so a fair quote starts with a clear look at the equipment. The main factors are:

The type of unit, such as a walk-in cooler, walk-in freezer, or other refrigeration equipment
The problem itself, from a worn gasket to a failed component
Parts needed and how easy they are to get
How hard the equipment is to reach
Whether the visit is a repair or routine maintenance
How much product is at risk and how fast the work needs to happen

A clear written quote should spell out the scope of work, which parts are included, any extras that might come up, and how changes are handled if the technician finds something new once the panel is open. You should be able to approve each step before it is done. For a free quote, call or send a request.

Questions to ask first

Before you hire anyone for refrigeration work in Detroit, ask:

Does this work require a license or permit? Ask what applies to refrigeration work in your area and whether the provider can show it.
Are you insured? Ask for proof if you want it, especially when the work happens in a space with product and staff.
What exactly is included? Find out whether diagnosis, parts, and labor are covered in the quote or listed separately.
How will scheduling work? Ask how quickly you can be seen and whether visits can avoid your busiest hours.
How will you keep me updated? You should know who to contact and how you will hear about findings and changes.

Common questions

How often should walk-in coolers and freezers be serviced?

It depends on how hard the equipment works. A busy restaurant kitchen with frequent door openings and heavy grease will usually need attention more often than a quiet storage cooler. Ask the technician what interval suits your unit after they have looked at it.

How is the price of a refrigeration repair worked out?

The quote reflects the type of equipment, the cause of the problem, parts, access, and the labor involved. A written quote should list these so you can see what you are paying for before approving the work.

Why does my walk-in freezer keep icing up?

Common causes include a worn door gasket letting in humid air, a door that does not close fully, a drain that is blocked, or a defrost problem. Because the causes differ, the coil and surrounding parts need to be inspected before anyone decides on a fix.

Can a cooler that runs warm be repaired, or does it need replacing?

Many warm-box problems come from a part or a buildup that can be repaired. Replacement becomes a conversation when the equipment is worn out or repair costs stop making sense. A diagnosis gives you the facts to decide.

Do you work with restaurants and stores, or only certain kinds of businesses?

We work with restaurants, stores, and other businesses that rely on walk-in coolers, walk-in freezers, and similar refrigeration equipment. If your setup is unusual, describe it when you call and we will tell you how we can help.

What should I do before the technician arrives?

Note the box temperature and when you first saw the problem, keep the area around the unit clear, and move any at-risk product if you can. Mention any recent changes, such as a new delivery pattern or a door that was damaged.
