Usually the clearest starting point: one indoor unit, one outdoor unit, and a path that can be checked from photos.
- Room size and heat gain
- Indoor wall and outdoor position
- Drainage, electrics, and access
Trust AC
Tell us the brand, unit count, symptoms, and access so Trust AC can advise the next step.
Servicing and fault visits are quoted per system, once we know what is installed.Tell us what you have

Existing systems
Service and fault enquiries are clearer when the first request includes model labels, controller errors, access photos, and a short symptom history.
Typical projects
These examples help customers recognise the kind of enquiry they are making before comparing equipment tiers or assuming a single headline price.

Usually the clearest starting point: one indoor unit, one outdoor unit, and a path that can be checked from photos.

The decision is not just room count. Pipe routes, simultaneous use, outdoor capacity, and service access all need a closer look.

Commercial timing, customer disruption, existing labels, and access risk can affect the work as much as equipment choice.
Service or fault
Existing systems are easier to look at when the first message separates routine servicing from symptoms, errors, access, and parts risk.
Send unit count, last service date if known, filter access, outdoor access, and whether the site is home or business.
Describe what changed, when it started, error codes, water leaks, noise, heating/cooling loss, or power issues.
If the system is old or unreliable, include labels and photos so Trust AC can compare service versus replacement.
Customers with existing indoor and outdoor units needing routine maintenance or fault diagnosis.
Number of units, access, service history, fault symptoms, and whether parts or a visit are needed.
Indoor unit labels, outdoor unit labels, controller errors, access path, and visible installation condition.
Some faults require an in-person visit and cannot be fully diagnosed online.
Before you send it
A clear first request helps Trust AC check the site faster and keeps the next step practical.
Once a year suits most homes and light commercial use. Heavier use, dusty environments or several units can justify more frequent visits, and manufacturer warranties often require servicing to stay valid.
It can be either. Weak cooling is often filters or airflow, which a service fixes; it can also point to a refrigerant leak, which needs a certified repair. Send the symptoms and any error code and we will tell you which is likely.
Yes. Send the brand, model and any labels on the indoor and outdoor units and we can advise on servicing, parts availability, and whether repair or replacement makes more sense.
