Car air conditioning not cooling: what to report

Weak cooling can have several causes. First distinguish air that is not cold from air that hardly flows: they lead to different checks, and a refrigerant top-up is not a universal repair.

Published 17 October 2026. General guidance; an inspection of your vehicle is still required.

The existing workshop image is illustrative; it does not document this specific fault. This guide cannot confirm whether your vehicle is safe to drive.

Separate cooling from airflow

Does the fan blow strongly but the air stay warm, or is airflow weak at every setting? Does cooling work briefly and then stop? Note whether the issue was gradual, followed a repair or appeared suddenly. Report unusual noise, smell and problems clearing the windows.

Why a refill may not be enough

A leak, insufficient refrigerant, ventilation or filter issues, compressor operation and electrical controls can all require consideration. Filling the system does not repair a leak or an electrical fault. The vehicle's system and refrigerant must be identified before the correct scope and quote can be proposed.

What to avoid doing yourself

Do not open refrigerant lines, use improvised refill products or assume that an air freshener fixes the reason for a smell. Products that mask odour do not establish the mechanical condition of the system. Tell the workshop about previous servicing, leak treatments or refrigerant work if known.

Noise, burning smell or poor visibility

Switch off the air conditioning if it develops a burning smell or strong unusual noise, and seek advice. If the engine overheats, stop safely rather than treating it as just a comfort issue. Do not continue driving if the windows cannot be kept clear enough for safe visibility.

Booking a targeted check

Include make, model, year, last air-conditioning service if known, airflow strength and when cooling stops. The cost depends on the confirmed work and the actual vehicle, not a generic figure for every system. If the concern is heating rather than cooling, use the separate heater guide so the symptoms are described accurately.

A useful service enquiry

Describe the symptom, when it occurs and any warning lights. Include the make, model, year and approximate mileage. Send relevant photographs or reports by email; the enquiry form does not accept attachments. Do not record or use your phone while driving.
