What Actually Happens During an Air Conditioning Installation?
If you’ve been considering air conditioning for your home, one of the most common questions is: What does the installation actually involve?
Understanding the process can make the decision much easier. At Delta T Installations Ltd, we aim to keep every installation straightforward, tidy, and stress-free — but there’s a lot that goes on behind the scenes to get it right.
Step 1: Initial Survey and Advice
Every installation starts with a site visit or consultation. This is where we assess:
- The size and layout of your room
- How the space is used (bedroom, living space, office, etc.)
- Heat levels and airflow
- The most suitable location for indoor and outdoor units
Getting this stage right is essential. A properly sized and positioned system will be more efficient, quieter, and more effective.

Step 2: System Selection
Not all air conditioning systems are the same. Based on the survey, we’ll recommend a system that suits your needs, typically from trusted brands like Mitsubishi, Fujitsu, or Daikin.
Factors considered include:
- Cooling and heating capacity
- Energy efficiency
- Noise levels
- Design and appearance
For most homes, a wall-mounted split system is the ideal choice, offering a balance of performance and simplicity.

Step 3: Installation Day
On installation day, our engineers will:
- Mount the indoor unit in the agreed position
- Install the outdoor unit in a suitable external location
- Connect refrigerant pipework and electrics
- Drill a small access hole (usually around 65mm) to link the indoor and outdoor units
We always aim to keep disruption to a minimum and leave your home clean and tidy.

Step 4: Testing and Commissioning
Once installed, the system is fully tested to make sure everything is working as it should.
This includes:
- Checking cooling and heating performance
- Testing airflow and temperature control
- Ensuring the system is operating efficiently
Step 5: Handover and Guidance
Before we leave, we’ll show you exactly how to use your new system.
This includes:
- How to control temperature settings
- Using timers and modes
- Basic maintenance tips
We’ll also answer any questions so you feel confident using your system straight away.

What Happens After Installation?
Air conditioning doesn’t stop at installation. To keep your system running efficiently, regular servicing is recommended.
This helps to:
- Maintain performance
- Improve air quality
- Extend system lifespan
- Prevent unexpected issues
