True Residential refrigerator repair
Built-in refrigerator
Flush with the cabinets, serviced from the front, and almost always repaired rather than replaced.
Refrigerator column
Separate refrigerator and freezer towers, each with its own sealed system — so a failure stays on one side.
Undercounter refrigerator
A single 15 to 24 inch unit under the worktop — front-vented, tightly enclosed, and easily starved of air.
