The short version: True Residential uses commercial-grade refrigeration and does not rely on numeric fault codes, so we diagnose by symptom. Most service calls are condenser, fan, door-seal and temperature-control issues, all defined genuine OEM parts.
True Residential brings restaurant-grade refrigeration into the home, and it shows up in high-end Lone Tree and Greenwood Village kitchens and bars. The heavy-duty design means the failure points are the same fundamentals as commercial equipment: airflow, seals and controls, all of which are serviceable.
Model Lines We Service
- Refrigerator and freezer columns: full-height built-in refrigeration.
- Undercounter refrigeration: refrigerator, freezer and drawer units.
- Wine and beverage centers: dual-zone wine columns and beverage units.
Symptom-To-Cause Table
| Symptom | Likely Cause | Our Fix |
|---|---|---|
| Cabinet drifting warm | Dirty condenser or failed fan | Clean the condenser, test and replace the fan |
| One zone off temperature | Damper, sensor or control | Test the sensor and control, replace the part |
| Compressor runs constantly | Door seal or airflow restriction | Inspect the seal, restore airflow |
| Wine unit too warm or cold | Thermistor or control fault | Test the thermistor, replace the control |
| Water pooling inside | Blocked defrost drain | Clear the drain path, confirm defrost |
Care That Keeps It Running
Vacuum the condenser two to three times a year so the heavy-duty compressor is not overworked, confirm the doors close squarely on their gaskets, and keep the interior vents clear so cold air can circulate. On wine units, avoid overpacking so airflow reaches every shelf.
When to Call Us
A cabinet drifting warm, a wine zone off temperature, or a compressor that never cycles off all call for a hands-on diagnosis and genuine OEM parts. We isolate the fault and replace the exact component.
True Unit Not Holding Temperature?

Built by a Commercial Company, and It Shows
True's ancestry is the most useful thing to know when something goes wrong. These machines were engineered by a company that built refrigeration for restaurants, where a failure costs a night's trade and a repair has to be quick, so they are designed to be serviced rather than sealed shut. Components are accessible, individually replaceable, and the refrigeration is built with headroom a residential-only design would not bother with. A True with a fault is very rarely a write-off; it is a machine waiting on a specific part that a technician can actually reach.
Wine Columns Want Two Things
The condenser needs vacuuming a couple of times a year, more insistently at our elevation than the manual assumes, because thin Front Range air already carries less heat away per pass and a dusty coil on top of that is what turns a cabinet holding a precise 55 degrees into one drifting quietly upward. The other is vibration. A wine cabinet is supposed to hold its collection still, so a compressor mount that has aged or a unit that has worked off level is doing more than making noise. Both are worth attention on their own merits rather than waiting for a temperature alarm.
