# How Often Built-In Refrigeration Needs Servicing in South Florida

## Why the interval is shorter here

Manuals are written for the country as a whole. A refrigeration column in Coral Gables works in a climate the average American cabinet never meets:

- **Heat, most of the year.** A compressor that would get cool nights off elsewhere does not here.- **Humidity.** More moisture to condense, more work per cycle, more melt water through the drain.- **Salt, near the water.** It reaches metal years ahead of any schedule written for a dry climate.- **Built-in installation.** A column sheds its heat through a grille into a cavity in joinery, which is a much smaller margin than a freestanding refrigerator standing in a room.

None of that makes the equipment fragile. It does make the maintenance interval shorter than the book suggests.

## The yearly list

**The condenser.** The single most useful thing anybody does to built-in refrigeration. Take the grille off, vacuum with a brush head, and look at what comes away. Fins that are gray and furry rather than metal-colored have been costing you compressor life for months.

Twice a year with pets in the house. Hair is the fastest thing there is at choking a coil.

**The drain.** Flush it with warm water while you are in there. [Ten minutes, and it prevents a puddle](/blog/cleaning-a-refrigerator-drain-line/).

**The door seals.** Paper test at four points a side, corners first, and dry the folds. A seal that has stopped gripping is the cheapest thing on this list and it does the most damage while nobody notices.

**The filters.** Water every six months; the odor filter yearly, and most people have never changed one at all.

**Clearance.** Check nothing has been stacked against the grille and that the cabinetry around the column has not been "improved" into a tighter fit.

## What needs a technician

Roughly every one to two years on built-in columns, and honestly less often than that on a well-maintained one:

- **The deep part of the condenser** an owner cannot reach with a vacuum- **Fan speed,** which matters because a fan that turns slowly looks perfectly healthy and behaves like a failure- **Temperature verification** across both compartments rather than at the display- **Seal and hinge adjustment** on panelled doors, which drop over years because they carry your cabinetry- **Anything with refrigerant in it,** which is not owner territory at all

## The arithmetic

A maintenance visit is [priced here](/services/appliance-maintenance/) and starts at less than a tenth of what a sealed-system repair does. That is not a reason to buy one every year; it is the reason we are comfortable arguing for one on a built-in column when we would shrug at it on a freestanding refrigerator.

The honest version: if you clean the condenser yourself, flush the drain, and keep the seals right, you have done most of the value. What a visit adds is the parts of that list you cannot reach and a measured answer on fans and temperatures.

## The signs that you are overdue

- The compressor sounds like it never stops- Ice building somewhere it did not use to- The cabinet takes noticeably longer to recover after the door has been open- A temperature alarm that clears itself and comes back weeks later

Any of those and the yearly list above is the place to start, in that order, before anybody is booked. If it is still doing it afterwards, that is a real symptom and worth a visit.
