What to Expect During a Professional AC Installation in London

Air conditioning in London installation can feel daunting—but knowing the steps makes it clear and reassuring. From initial surveys to final handover, a professional job ensures comfort and efficiency. This guide will explain what happens during installation, highlight when to call an AC technician in London, and illustrate how your aircon in London journey unfolds.

 


Initial Consultation & Site Survey

The first step in a professional installation of air conditioning in London is the initial consultation and site survey. This vital stage sets the tone for the entire process. During the consultation, an experienced AC technician in London visits your home or business to understand your cooling and heating needs. They'll ask questions about how the space is used, the number of occupants, and any comfort issues you’ve experienced—such as hot spots, poor airflow, or excess humidity.

Following the discussion, the technician conducts a detailed site survey. This includes taking precise measurements of rooms, inspecting existing insulation, checking window placements, and evaluating sun exposure. Homes in London often feature older construction or unique layouts, making this survey essential for selecting a suitable system. The technician will also assess the most practical routes for pipework, power supply, and drainage.

If there are restrictions due to building regulations, listed property status, or planning permissions (particularly common in London boroughs), these are identified early. The technician may also check noise sensitivity in densely populated areas where outdoor unit placement is critical.

By the end of this stage, you’ll have a clearer understanding of the type and capacity of aircon in London best suited to your home, helping avoid future issues and ensuring comfort all year round.

 


Project Planning & Design

Once the site survey is completed, the planning and design phase begins. This step ensures that your air conditioning in London is tailored to both your property’s requirements and your personal preferences. Based on the survey findings, the installation team drafts a custom plan. It includes the recommended system type (split, multi-split, or ducted), placement of units, and the full layout for electricals, drainage, and refrigerant pipework.

Professional installers from companies like Arcas Air Conditioning use this stage to optimise energy efficiency, aesthetics, and performance. For example, they’ll select indoor unit placements that ensure even air distribution without obstructing furniture or lighting. Outdoor units are carefully positioned to reduce noise impact, avoid sunlight exposure, and comply with local regulations.

Additionally, this phase includes reviewing:

  •  Electrical load requirements
  • Ceiling or wall mounting options
  • The total cooling/heating load (BTUs)
  • Pipe insulation and line set routing
  •  Noise-reduction strategies

You’ll also receive a breakdown of costs and installation duration. For more complex homes or larger systems, this may involve CAD drawings or manufacturer-approved layout plans.

In short, proper planning ensures that your aircon in London not only functions efficiently but integrates smoothly with your property. It’s the key to an installation that runs on time, within budget, and without complications.

Removing Old System (If Applicable)

If replacing an existing system:

  • The technician safely recovers any refrigerant
  • They disconnect and remove indoor and outdoor units
  • They protect your property with dust sheets and covers
  • They inspect old pipework and suggest whether it needs replacement

Proper removal of your old system prevents leaks and ensures your new unit performs as intended.

 


Installing Indoor & Outdoor Units

On installation day, here’s what happens:

Indoor Unit Fit-Out

  • A hole (typically 70–100 mm) is drilled through an external wall
  • Wall‑mount bracket is secured, levelled and reinforced
  • Pipework, electrical and drain piping is run through the hole
  • The indoor unit is attached and sealed neatly

Outdoor Unit Fit-Out

  • A secure, level pad or wall bracket is fixed outside
  • The condenser is installed and connected to the pipework
  • Refrigerant lines are brazed and insulated
  • Drain and power cables are routed and protected

From start to finish, a typical split system takes around 4–6 hours. Complex multi‑split or ducted systems may take longer.

 


Refrigerant Charging & System Setup

With units installed, your AC technician in London will:

  • Evacuate the installation to remove air and moisture
  • Charge the system with correct refrigerant volume
  • Check for leaks and ensure proper pressure
  • Test thermostat function, airflow and temperatures
  • Fine‑tune settings for optimal performance

This stage is vital: incorrect refrigerant levels or poor pressure can reduce efficiency, harm performance, and risk costly damage.

 


Final Checks & Client Handover

Before leaving, your installer will:

  • Clean up the work area and remove debris
  • Demonstrate how the system works, including modes and remotes
  • Provide maintenance advice—filter cleaning, drain care, servicing frequency
  • Confirm that you're satisfied and that the system meets design specs

At this point, your aircon in London installation is fully operational and ready for use.

 


Why Professional Installation Matters

Opting for a professional installation ensures:

  • Efficiency: Proper design saves energy and lowers bills
  • Reliability: Correct installation prevents breakdowns
  • Warranty protection: Many brands require certified installation
  • Compliance: Certified installers ensure refrigerant handling meets regulations and UK standards

With correct installation, your air conditioning in London will last longer and perform better.

 

 


Aftercare & Maintenance Tips

To ensure longevity and efficiency:

  • Clean or replace filters every 1–2 months
  • Keep outdoor units free from debris and vegetation
  • Book annual servicing with an AC technician in London for checks and refrigerant top‑up
  • Watch for warning signs like odd noises or decreased airflow

Proper maintenance helps your aircon in London perform well and prevents costly repairs.
