Engineer-Led Fault Finding
Find The Cause First
Clear repair advice based on what the system is actually doing
Find The Cause Before The Fix
Similar symptoms can have different causes. Good repair work starts with evidence, testing and diagnosis.
An air-conditioning system can stop heating or cooling for many reasons. The issue may involve controls, airflow, drainage, power, sensors, components, the outdoor unit or another part of the installation.
W2 Refrigeration Services takes an engineer-led approach: understand what happened, inspect the system, carry out appropriate checks and explain what has been found before recommending the next step.
System Not Starting
No response, unexpected shutdown or failure to run normally.
Heating Or Cooling Failure
The unit operates but does not deliver the expected temperature.
Water Or Drainage Issue
Dripping, staining or moisture appearing around the indoor unit.
Error Code Or Warning
A display, light or controller indicates an operating fault.
Common Fault Symptoms
What Is Your Air Conditioner Doing Differently?
You do not need to diagnose the fault yourself. A clear description of the symptom helps W2 understand what information is needed and whether a repair visit is appropriate.
Not Heating Or Cooling
The system runs but does not change the room temperature as expected.
Weak Or Uneven Air
Air movement has reduced, changed or stopped from part of the unit.
Unusual Noise Or Vibration
New rattling, buzzing, vibration or other operating sound is present.
Leaking Or Dripping
Water, moisture or staining appears around the unit or drainage route.
Error Code Displayed
The controller or unit shows a code, flashing light or warning indication.
Help W2 Assess The Enquiry
A Few Details Up Front Can Make The First Visit More Productive.
A few photographs and basic details can make the first conversation more productive. Do not remove covers or access unsafe areas to obtain them.
Property & Location
Home, office, shop, salon or other premises, plus the postcode or area.
System Details
Make and model if visible, number of units and approximate installation age if known.
Fault Description
What the system is doing now, when it changed and whether the issue is constant or intermittent.
Code Or Warning
A clear photograph or exact wording of any error code, light or controller message.
Safe Photographs
Accessible images of the indoor and outdoor units and any visible leak or damage.
The Repair Process
Diagnose The Fault. Explain The Options. Take The Right Next Step.
Understand The Problem
Confirm the symptoms, history and any error information supplied.
Inspect & Test
Carry out appropriate checks to narrow down the cause of the problem.
Explain What Was Found
Describe what has been identified and whether further work or parts may be required.
Recommend The Right Route
Repair where practical, undertake further investigation if needed or discuss replacement when that is the sensible option.
Not Every Fault Ends The Same Way
Not Every Fault Needs The Same Answer.
Repair Makes Sense
Where the cause is identified and an appropriate repair is available, W2 can explain the work needed and the next step.
Further Investigation Is Needed
Some intermittent or component-related faults may require further testing, system information or parts availability to establish the full route forward.
Replacement Is The Better Route
If the system condition, repair practicality or equipment support makes repair unsuitable, W2 can explain why replacement should be considered.
If The System Appears Unsafe
Stop Using It And Seek Appropriate Help.
If you notice burning smells, smoke, sparking, obvious electrical damage or another immediate safety concern, stop using the system if it is safe to do so. Do not remove covers or attempt an electrical or refrigerant repair yourself.
Need Help With A Fault?

Before Requesting A Repair Visit.
Useful information for homeowners and businesses with a faulty air-conditioning system.
What types of air conditioning faults can W2 investigate?
W2 can assess domestic and smaller commercial systems with issues such as failure to start, loss of heating or cooling, reduced airflow, unusual noise, drainage concerns and error indications, subject to the equipment and work required.
What should I send before a repair visit?
Provide the location, property type, system make and model if visible, number of units, fault symptoms, any error code and safe photographs of the indoor and outdoor equipment.
Can an air conditioning system always be repaired on the first visit?
Not always. The cause may require further testing, a specific part or additional system information. W2 will explain what has been identified and the next practical step.
Should I keep resetting a system showing an error?
Repeated resetting can hide useful fault information and may not be appropriate. Record the code or warning, stop using the system if there is a safety concern and seek qualified advice.
Is an air conditioning repair the same as servicing?
No. Repair work addresses a specific fault or failure. Servicing is routine maintenance for an operating system. A service visit may identify a fault requiring separate diagnosis.
Does W2 offer emergency or 24-hour repairs?
W2 does not claim a 24-hour emergency repair service. Send the system details and location so availability can be confirmed. For an immediate danger, contact the relevant emergency service or qualified emergency provider.
Which areas does W2 cover?
W2's main repair area is Glasgow and Central Scotland. Include the property location with your enquiry so availability can be confirmed.
