What a maintenance visit covers

The list we work through

1. Condenser coil and fan. Grille off, coil brushed and vacuumed along the fins, the fan blade cleaned and turned by hand to feel for a dry bearing.
2. Door gaskets. Each edge checked for a seal, a split or a flattened corner, then wiped clean.
3. Hinges and doors. Does each door swing shut and hold? A tired closing cam shows up here first.
4. Defrost drain. The path the meltwater takes, checked for a blockage before it turns into ice under the drawers.
5. Temperatures. Both compartments measured against Sub-Zero’s targets of 38°F and 0°F.
6. Airflow inside. Vents found and freed; food packed against them chokes the compartment.
7. Filters. The water filter’s status, and the air purification cartridge, which Sub-Zero says to change when its light flashes or after about a year.
8. Ice maker. One harvest watched from fill to drop, on units that have one.

At the end you get a plain account of what we found, and nothing replaced without your say-so.

When to book it

Sub-Zero spaces condenser cleanings six to twelve months apart, closer together in homes with pets. In Cherry Hills Village we book one of those visits for just after the cottonwood cotton, so the coil goes into the hottest weeks clean. The cottonwood season page explains why, and the month-by-month list covers the rest of the year.

What it costs

The visit opens with the $89 call-out, which pays for the inspection. Cleaning and any repair are priced before they happen, and nothing goes ahead without your yes. If the list turns up a worn part, typical ranges are $320–$670 for a fan motor and $270–$670 for a door gasket. Ranges, not quotes: you approve one figure first, and the call-out counts toward it.
