| Unit or household | Interval | Threshold | What to do |
|---|---|---|---|
| Full-size or Designer unit | Every 6–12 months | Grey lint across the fins | Power off at the control; brush along the fins |
| Any unit, dogs or cats at home | Toward 6 months | Hair on the fins or fan guard | Clean at the short end of the range |
| Undercounter unit whose guide says so | Every 3–6 months | Dust across the kickplate louvres | Your model's guide wins over this table |
| Just after a cleaning | Up to 24 hours | Temperatures still off a day later | Leave it running, then read it again |
| Call when | the interval has been kept and the unit still runs warm or never pauses. Sub-Zero Repair Issaquah, (425) 272-6613 | ||
The table is the answer: the manufacturer’s interval is six to twelve months, and the rows only decide which end of it is yours. Two dogs on a wooded Squak Mountain lot put a kitchen at the short end; a household with no pets can run the full year.
The reason is heat. A coil furred with lint sheds what the unit pulls out of the food slowly, so the compressor runs longer to keep up. If the last row describes your kitchen, call Sub-Zero Repair Issaquah at (425) 272-6613.

The short answer, then what people ask next
How Often Should a Sub-Zero Condenser Be Cleaned?
Every six to twelve months, which is Sub-Zero's own interval, and closer to six in a home with dogs or cats. Some older undercounter guides ask for every three to six. If the coil is clean and the unit still runs warm, call Sub-Zero Repair Issaquah on (425) 272-6613.
What happens if the condenser is never cleaned?
Heat leaves the cabinet more slowly, so the compressor runs longer to hold temperature. The manufacturer warns that skipping the cleaning can lead to temperature loss, mechanical failure or damage, and its troubleshooting for a warm or constantly running unit starts by asking whether the condenser is clean.
