What Does a Free AC Check Really Include
“Free AC check” can mean a sales glance, a temperature snapshot or the first step of a defined diagnostic route. The customer should know which one before arriving.
Our free check is a no-dismantling condition screen for eligible booked vehicles. It records the complaint, observes accessible cooling and airflow clues, and tells you whether no action, maintenance or paid diagnosis is the correct next step. It is not free refrigerant, hidden leak testing or unlimited fault isolation.
The price is zero, the boundary must still be written
A free screen has value when it prevents the wrong paid service. It becomes misleading when the customer expects a complete pressure, electrical and leak diagnosis but receives only a quick visual followed by a parts quote.
We publish the boundary so owners can decide whether the free check matches their question. If the car already blows hot, repeatedly loses gas, shuts down after twenty minutes or has a major component quote, it may need the paid diagnostic route from the beginning.
What we will screen without dismantling
Complaint and history
Record vehicle, refrigerant label where accessible, previous refills or repairs, when the symptom appears and the owner’s decision goal.
Cooling snapshot
Observe centre-vent output under stated ambient, blower, recirculation and operating conditions. A snapshot is not a full performance diagnosis.
Airflow observation
Compare outlet strength, blower sound and obvious zone differences without removing the dashboard, blower or HVAC case.
Accessible visual screen
Look for obvious condenser damage, hose condition, service-port issues, belt concerns where applicable and visible oil or dye clues.
Fan and operating clues
Observe accessible condenser-fan behaviour and whether the complaint changes at idle, speed or after heat soak.
Next-route explanation
Classify the result as monitor, maintenance, package service or paid fault diagnosis. No outside work proceeds without approval.
Free does not mean every test is hidden inside
The screen does not promise gauge connection, refrigerant recovery, recharge, nitrogen pressure testing, UV dye addition, electronic leak detection, scan-tool diagnosis, electrical circuit testing, filter removal, evaporator cleaning, dashboard access, parts or repair.
Those actions use equipment, consumables, specialist time or physical access and must be quoted as a separate service or diagnostic branch. The customer sees the reason and price before approving them.
Outside the AED 0 screen
- R134a or R1234yf refrigerant
- Pressure and charge diagnosis
- Nitrogen, dye or electronic leak testing
- Electrical load, wiring or scan-data diagnosis
- Filter, blower, trim or HVAC-case removal
- Cleaning, disinfection, seals or consumables
- Repair estimate that requires hidden access
- Guarantee against future failure
The free check should end with a route, not pressure
No abnormality is reproduced inside the free screen. Keep the baseline and return if the pattern appears under specific heat or driving conditions.
An accessible maintenance issue or gradual performance concern justifies a clearly scoped Basic or Standard package with an exact price.
Warm air, repeat gas loss, electrical or intermittent failure, strong leak evidence or a major part decision needs paid diagnostic depth.
See Car AC Service Packages Compared for the difference between maintenance and diagnosis.

Free inspection and free diagnosis are different promises
Vague free check
- No checkpoint list before arrival
- “Needs gas” without leak or charge context
- Pressure to approve parts immediately
- Paid additions appear after connection
- No written result if the owner declines
The problem is not that the screen is short. The problem is that the customer cannot see its boundary.
Our itemised free screen
- Eligibility and no-dismantling scope confirmed
- Six checkpoints stated publicly
- Refrigerant, leak and electrical work excluded clearly
- Monitor, service or diagnose result
- Separate written approval for the next step
A paid diagnosis is recommended when the question already exceeds the free boundary.
Know when the free check is enough
| Customer situation | Free check value | Likely next route |
|---|---|---|
| AC feels normal before summer | Creates a useful baseline | Monitor or booked maintenance |
| Cooling has gradually weakened | Screens airflow, fan and visible clues | Standard service or diagnosis depending on finding |
| AC blows hot | May identify an obvious route but cannot prove cause | Full paid diagnostic |
| Gas disappears repeatedly | History and visible screen only | Leak-test scope |
| Cooling fails after twenty minutes | Snapshot may not reproduce the failure | Timed diagnostic appointment |
| Rear AC differs from front | Basic zone comparison | Front-versus-rear diagnostic branch |
| Garage already quoted compressor or evaporator | Not a substitute for verification | Evidence review and full diagnosis |
| R1234yf contamination suspected | Do not connect normal equipment | Identification and controlled recovery route |
What transparency looks like at the handover
Normal family car
The free screen reproduces normal cooling and airflow with no visible concern. The owner receives a baseline and no repair pitch.
Blocked-looking filter route
Weak airflow is observed, but filter removal is outside scope. A separate filter or airflow service price is offered without automatic approval.
Hot air at idle
Fan behaviour or heat-load clues move the vehicle to a paid diagnosis. The check does not declare a compressor from one observation.
Repeat top-up history
The owner is told that another gas addition is not included and a leak-test quote is the appropriate next purchase.
Hidden evaporator suspicion
The free screen records history but does not justify dashboard removal. Electronic, dye or pressure evidence is quoted separately.
Customer declines further work
The free check remains free. The owner receives the route and can decide later without an invented inspection charge.
What each included item can and cannot prove
Symptom intake
A useful free check begins before the bonnet opens. Tell us whether cooling is weak from startup, only in afternoon heat, only at idle, after a long drive, on one side or only in the rear. Include previous refill dates, collision or condenser damage, battery work, noises, smells and warning messages. This history helps choose what can be observed during the free appointment.
The intake cannot prove a leak, compressor failure or sensor fault. It creates a reproducible question. If the complaint requires twenty minutes of driving or a rare heat-soak condition, the free slot may not be long enough and a timed paid diagnostic should be booked instead of pretending the symptom was cleared.
Vent snapshot
Vent temperature can show whether cold air is reaching one selected outlet under the conditions present. We record the useful context rather than presenting one number as a verdict. Blower speed, recirculation, ambient heat, sun load, engine speed, door position and test duration all affect the result.
A cold centre vent does not prove the total refrigerant charge is correct, every cabin zone works or the system will remain cold on the road. A warm vent does not identify the failed component. Pressure, charge, electrical and leak conclusions belong to the paid branch.
Airflow and zone observation
We compare the owner’s report with obvious outlet strength, blower sound and accessible front or rear differences. A fan that sounds fast while little air reaches the vents can point toward a filter, evaporator restriction, icing, duct or door branch. Different temperatures across zones can point toward distribution or local rear testing.
The free check does not remove filters, blowers, side trim or dashboard panels. It cannot inspect a buried door or measure every circuit electrically. Its job is to stop a weak-airflow complaint from being sold an automatic gas refill.
Accessible visual screen
Obvious condenser impact, damaged accessible hoses, missing service-port caps, severe oil staining, belt concerns where applicable and visible wiring damage can guide the next step. Old dye or oil residue is treated as a clue, not automatic proof of an active leak. We also note when access is blocked by covers or vehicle design.
No undertray, rear interior, HVAC case or dashboard is removed within the free screen. If a hidden leak is suspected, the customer receives the appropriate nitrogen, dye, electronic or staged access quote before testing begins.
Fan and operating observation
Accessible condenser-fan behaviour can help explain an idle or heat-load complaint, but one visual moment does not prove fan command, motor current, sensor plausibility or control-module operation. Some vehicles vary fan strategy normally, and hybrids or EVs use different operating logic.
If fan behaviour appears abnormal, paid electrical or system diagnosis confirms power, ground, command, pressure inputs and actual cooling response. We do not use the free check to sell a fan merely because it was not turning at one uncontrolled instant.
Route recommendation
The final included deliverable is a next decision. Monitor means no abnormality was reproduced within the screen and the owner should record the conditions if it returns. Service means an itemised maintenance package is proportionate. Diagnose means the symptom requires pressure, leak, electrical, scan or timed failure testing.
The recommendation is not permission to perform paid work. You receive the proposed scope, exact AED price, important exclusions and expected time first. You can approve, decline or seek another opinion while keeping the free screen result.
Eligibility protects the promise. The free screen is subject to booking confirmation, suitable workshop capacity, vehicle accessibility and a safe operating condition. A contaminated refrigerant system, collision-damaged vehicle, unsafe electrical condition, dismantled AC circuit, specialist classic conversion or high-voltage concern may need a paid controlled route immediately. We will say that before the visit when the information is available.
No purchase should be required to keep the screen free. If the owner declines the proposed service or diagnosis, the itemised check remains AED 0 as booked. Consumables, collection, recovery, parking, dismantling or extended testing are not quietly added. If a different service is requested during the visit, its price and approval stand separately.
Free is not a warranty. The result describes the condition observed during a limited screen. It cannot guarantee that an intermittent electronic fault, microscopic leak, future stone impact or ageing component will not fail later. Warranty attaches only to qualifying written repair work, not to a preventive observation.
A real odour job shows why the free check must stop before hidden diagnosis
A documented Car AC Heroes case involved a 2019 Range Rover Sport with 85,000 km. The owner reported a persistent sour, wet-dirt smell mixed with stale cigarette smoke, strongest when the AC blower was first switched on. That symptom could be recorded during a no-dismantling screen, but the free check alone could not honestly name the physical source.
Further inspection found two separate causes: the evaporator drain was partially clogged with dust and debris, allowing condensate to remain in the HVAC housing, and the cabin filter was heavily contaminated with desert dust and smoke residue. Smoke contamination was also present in the interior. The repair therefore started with source removal: the drain was cleared, the contaminated filter was replaced and the HVAC/interior cleaning route addressed the physical residue. Ozone was treated only as a supplementary step after the sources were dealt with, not as a substitute for repair.
This is the boundary the AED 0 screen is designed to protect. It can identify the symptom, accessible clues and the correct next branch. It should not pretend that a limited visual and operating check has already proved a hidden evaporator, drainage, refrigerant or electrical fault.
Book the check that can actually answer your question
Send the vehicle, refrigerant label and symptom. We will confirm whether the itemised free screen is suitable or whether paid diagnostic depth will save you a wasted visit.
Before travelling, send enough detail to avoid the wrong appointment. Include make, model, year, refrigerant label if visible, whether the vehicle is safe to operate, the exact cooling pattern and any recent invoice. For tower parking, collection requests, rear-AC SUVs, EVs or cars with an empty system, mention access and vehicle condition. We can then confirm whether the AED 0 screen is suitable at the workshop or whether a different service route should be priced from the start.
After the check, ask for the classification in plain words. If the answer is monitor, ask which pattern should trigger a return. If it is service, ask which maintenance item is included and what it cannot repair. If it is diagnose, ask which branch will be tested, the fixed or agreed fee, what additional access requires approval and what written result you receive. This turns “free check” into a useful gateway rather than a sales slogan.
The most honest outcome can be that no paid work is recommended today. The second most honest outcome is a paid diagnostic recommendation when the free screen cannot prove the cause. The dishonest outcome is pretending a limited free observation already proves an expensive compressor, evaporator or refrigerant repair.
