Called Monday about our Wolf range — burners were running hot after we moved in. Technician arrived Tuesday with parts already on the truck. Turns out the altitude orifices had been installed wrong by the previous owner. Calibrated on the spot, everything has been precise since. Very professional, explained every step.

Premium Refrigerator Repair Across Denver Metro
Wolf builds cooking, not cold — so refrigeration is where our technicians switch into Sub-Zero, Viking, Thermador and Miele mode. We repair built-in, column and integrated units at the sealed-system level, not just the parts that bolt on the front.
First, an honest note
Wolf doesn't make refrigerators — but we service the ones that live beside them
If you found us searching for Wolf refrigeration, here is the plain truth: Wolf builds ranges, ovens and cooktops, not refrigerators. The cold half of a high-end kitchen almost always comes from a sister or rival brand — Sub-Zero most often, but also Viking, Thermador, Miele, Gaggenau, Dacor and Bosch. Those are exactly the units our technicians repair every week.
Built-in refrigeration is a different animal from the freestanding box at a big-box store. A Sub-Zero column or an integrated panel-ready unit is engineered to run for two decades behind cabinetry, with dual sealed systems, foam-insulated cabinets and control boards that expect a technician who knows the platform. That is the level we work at, and it is why the diagnosis matters more than the part.
Most refrigeration calls we take in Denver land in one of a few families. The unit is not cooling — the compressor runs but the box stays warm, which points at a sealed-system fault: a refrigerant leak, a failed compressor, or a clogged capillary or filter-drier. Or it is too cold, freezing produce in the fresh-food side, which usually traces to a stuck damper, a drifted thermistor or a control board misreading temperature. A third family is defrost failure: frost sheets over the evaporator, airflow chokes, and the fresh-food compartment warms while the freezer still feels cold — almost always a defrost heater, defrost thermostat or the timer/board that runs the cycle.
Then there are the parts you touch every day. A door gasket that has taken a set no longer seals, so the compressor runs long and condensation forms at the hinge. The dispenser quits, the interior LED lighting flickers out, or a control board throws error codes and forgets its settings after a power blip. On dual-compressor Sub-Zero units, one system can fail while the other soldiers on, so the freezer holds while the refrigerator creeps warm — a pattern a generalist often misreads as a thermostat when it is really the refrigerator-side sealed system.
Because built-in units are worth restoring rather than replacing, an accurate diagnosis pays for itself. Guessing at a compressor when the real fault is a $40 filter-drier, or condemning a control board when a thermistor drifted, is how repairs go wrong. We test the whole cold chain — compressor draw, evaporator and condenser temperatures, defrost function and control logic — before we name a part or a price.

What we repair
Built-in, column and integrated refrigeration — end to end
We diagnose the sealed system and the electronics together, so you are not paying for a swapped part that treats a symptom instead of the cause.
- Sealed-system faults — compressor, evaporator, condenser
- Refrigerant leaks, recharge and filter-drier replacement
- Not cooling, warming fresh-food side, warm on one system
- Too cold — freezing produce, stuck dampers, drifted thermistors
- Defrost faults — heater, thermostat, timer and board
- Condenser fan, evaporator fan and airflow problems
- Main control and user-interface boards, error codes
- Door gaskets, hinges, alignment and sagging integrated panels
- Ice maker, water dispenser and inlet-valve issues
- Interior LED lighting and dispenser controls
How the visit goes
From knock to holding temperature
01
Identify the platform
Sub-Zero, Viking, Thermador, Miele or another premium brand — plus model and serial, so we arrive with the right gaskets, boards and sealed-system parts.
02
Read the whole cold chain
We check compressor draw, evaporator and condenser temperatures, airflow, defrost function and control readings before naming a fault.
03
Repair with factory-grade parts
Genuine or factory-grade components fitted to spec — no universal gaskets or mismatched boards that cause the next callback.
04
Verify it holds
We let the box pull down and confirm it holds temperature through a full cycle, so you are not left wondering overnight.

Direct answer
Does Wolf make refrigerators, and can you fix my Sub-Zero?
Wolf makes cooking appliances, not refrigerators — the cold side of a luxury kitchen is usually a Sub-Zero, and that is one of the brands we specialize in. As an independent Denver company we repair built-in, column and integrated refrigeration from Sub-Zero, Viking, Thermador, Miele and other premium makers. Call (720) 790-9436, answered 24/7, and we will bring the right parts.
Direct answer
My built-in fridge is warm but the freezer is fine — what's wrong?
On a dual-system unit like a Sub-Zero, the two compartments run on separate sealed systems, so the refrigerator side can fail while the freezer holds. That pattern usually points to a defrost fault, a fan or damper problem, or a sealed-system issue on the fresh-food circuit rather than a simple thermostat. It is worth a same-day look before food spoils.
Direct answer
Is it worth repairing an old built-in refrigerator or should I replace it?
Built-in and integrated units are engineered to last 15 to 20 years and often cost many thousands to replace, so a targeted repair is usually the smart call. A $89 diagnostic tells you exactly what failed and what it costs to fix, applied toward the repair if you proceed, so you can decide with real numbers instead of a guess.
What it runs
Indicative refrigerator-repair pricing
Refrigeration varies enormously by brand, generation and fault, so these are starting points, not quotes. You always get a firm number before any work begins.
Diagnostic / service callApplied toward the repair if you proceed

Every figure is a starting estimate. Final pricing is set after an on-site inspection, because premium refrigerators differ dramatically by brand, generation and the exact failure — a stuck damper and a compressor are worlds apart. The flat $89 service call applies toward the repair if you proceed, and we never charge for work you have not approved.
Refrigeration FAQ
Questions we hear about built-in fridge repair
Do you service Sub-Zero column and integrated refrigerators specifically?
Yes — built-in, column and panel-ready integrated Sub-Zero units are among the most common jobs we do, along with the same styles from Viking, Thermador and Miele. We handle the sealed system, defrost, controls, gaskets and dispensers on all of them.
How fast can you get to a fridge that has stopped cooling?
We offer same-day and next-day availability, and the phone is answered 24/7. A refrigerator that has quit is a priority call, so tell us the brand and symptom and we will route a technician with the likely parts on the van.
There's frost building up inside — is that a defrost problem?
Usually, yes. A sheet of frost over the evaporator points to a failed defrost heater, defrost thermostat or the timer or board that runs the cycle, which then chokes airflow and warms the fresh-food side. We test the full defrost circuit rather than swapping one part and hoping.
Are you an authorized Sub-Zero or manufacturer service center?
No — we are an independent company and are not affiliated with, authorized by or endorsed by Sub-Zero, Wolf Appliance or any manufacturer. Our technicians are factory-trained and we fit factory-grade parts, which keeps our scheduling and pricing flexible while holding to brand-level standards.
Do you work across the Denver metro and Front Range?
Yes, throughout the Denver metro and along the Front Range, service performed daily from 8am to 6pm. Whether you are in the city or the foothills suburbs, we cover it.

Trusted in Denver kitchens
Recent customer experiences with our appliance repair service.
Our Wolf oven was reading 50 degrees low — we'd been overcompensating for months. The tech tested it, replaced the temp sensor, and re-ran calibration. Baking has been completely different since. Honest diagnostic, fair price, no upselling.
Three igniter clicks on the left burner, then nothing. A different company quoted replacing the entire control board — nearly $900. Denver Wolf Repair diagnosed a faulty igniter module and fixed it for a fraction of that. Trust the specialists.
Wolf dual-fuel range with erratic simmer on the gas side. Technician found the altitude conversion had never been completed by the original installer — corrected it in under an hour. At 5,280 feet this is apparently common. Highly recommend for anyone with a similar setup.
Sub-Zero stopped cooling — called at 7 am, someone was here by 11. Condenser fan, which they had in the van. Groceries were saved. These technicians clearly know this equipment cold.
Wolf range hood stopped capturing smoke. Tech found a failing blower motor, ordered the part and installed it within two days. No upsell attempts, no unnecessary extras. Clean and done right.
Scheduling was easy, tech was on time. Oven door seal was cracked and they replaced it cleanly. Would have given 5 stars but had to wait a few extra days for the part. Otherwise thorough diagnostics and honest about what actually needed fixing.
Control board on our Wolf oven started throwing error codes. I dreaded a huge bill, but the tech walked me through exactly what was wrong before touching anything. Repair was done same visit. Professional from first call to sign-off.
