Reading the codes, testing the sealed system and checking the airflow is what turns “it is not cooling properly” into a repair with a price on it. The fee is credited toward the work when you go ahead, so on a job we carry out it is not an extra line on the bill. ### What the technician does on site - Reads the active and stored codes, and asks what the unit has been doing rather than only what it is doing now - Tests the sealed system and the airflow before anything is opened - Checks the inexpensive causes first — gasket, grille clearance, condenser condition - Writes down the scope and the price, and waits for your approval ### What you can do before we arrive Have the model number from the plate inside the door, and a photograph of the display if there is a code on it. If there is more than one unit at the address, say so when you book — a second unit seen on the same visit costs less than a second visit. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about Sub-Zero diagnostic visit Yes. It starts at $95 and comes off the bill when you go ahead with the work, so on a job we carry out it is not an extra line. You pay the diagnostic fee and nothing else. The visit, the testing and the written scope have happened either way, and you leave knowing what is wrong. Usually under an hour for the diagnosis itself. Whether we finish the repair the same day depends on the part and on how the unit is built into the cabinetry. We can narrow it. With the model number and a description we will tell you the likely causes and the range — but the same symptom has several causes hundreds of dollars apart, and only the appliance settles which is yours.
