Split AC Installation & Commissioning

Precision installation from wall bracket to first cool air — by certified HVAC engineers.

A split AC system is only as good as its installation. Incorrect pipe routing, improper vacuuming, or wrong refrigerant charge — all common shortcuts — cause efficiency loss of 15–30% from day one. Our installations follow SASO and manufacturer specifications precisely: every copper joint is flared and brazed, every system is vacuum-tested to 500 microns, and every unit is commissioned with full refrigerant pressure logging.

What's Included

Site Survey & Load Calculation

We calculate the exact cooling load for your room — square footage, insulation, window orientation, occupancy — to specify the correct capacity. Oversized units cycle too fast and fail early; undersized units run non-stop and can't cool.

Bracket & Pipe Routing

Heavy-duty wall brackets rated for 3× unit weight, installed into structural concrete (not just plaster). Copper pipe routing optimised to minimise bends and pipe run length — every metre of unnecessary pipe reduces efficiency.

Copper Pipe Flaring & Brazing

All copper joints flared to ISO 7241 standard and silver-brazed with nitrogen purge running to prevent oxidation inside the copper circuit. This eliminates the pinhole leaks that develop within 2–3 years in poorly installed systems.

Vacuum & Pressure Testing

System evacuated to below 500 microns using a two-stage vacuum pump. Vacuum held for 30 minutes and measured — if it rises, there is a leak. We find and fix it before charging with refrigerant, not after.

Refrigerant Charging & Commissioning

System charged to manufacturer-specified superheat and subcooling values using calibrated manifold gauges. Commissioning report provided with suction/discharge pressures, current draw, and outlet temperature readings.

Electrical Connection & Safety Check

Correct cable sizing, RCD protection, and dedicated circuit breaker installed. All connections torqued to specification and tested under load before handover.

How It Works

1
Site Survey
Measure the room, check wall construction, identify cable and pipe routing path, confirm electrical supply capacity.
2
Bracket & Trunking Install
Install indoor unit bracket, outdoor unit stand or wall bracket, and PVC trunking for cable and pipe runs.
3
Indoor Unit Mounting
Mount indoor unit, feed copper pipes and drain tube through wall, connect drain to external discharge point with 1/50 slope.
4
Outdoor Unit Installation
Mount outdoor unit, connect copper pipes, and run electrical cabling. Ensure minimum clearances for airflow per manufacturer spec.
5
Vacuum & Leak Test
Evacuate system, hold vacuum for 30 minutes, confirm integrity before opening refrigerant service valves.
6
Commissioning & Handover
Power up, measure operating parameters, demonstrate remote control functions, issue commissioning certificate.

Pricing Guide

Indicative Rates — Split AC Installation & Commissioning

1-ton split AC installation: SAR 400–650. 1.5-ton: SAR 500–750. 2-ton: SAR 600–900. Multi-split (per additional indoor unit): SAR 300–500 extra. Prices include labour and standard fittings — excludes unit purchase price and any civil works (core drilling, trunking extension).

Frequently Asked Questions

How long does a split AC installation take in Saudi Arabia?

A standard single split unit installation takes 3–5 hours from arrival to commissioning. A villa with 4–6 units takes one full day (8–10 hours) with our 2-person team. We schedule multi-unit installations to minimise disruption to occupied rooms.

What is the correct AC size for my room?

As a starting rule: 1 ton (12,000 BTU) per 15–18 m² in Saudi Arabia's climate. However, rooms with large west-facing windows, poor insulation, or high occupancy need more capacity. Our free site survey calculates this precisely — avoid oversizing, which causes short-cycling and humidity problems.

Do you install all AC brands in Saudi Arabia?

Yes. We install Daikin, Mitsubishi Electric, LG, Samsung, Gree, Midea, Carrier, Trane, and all other brands available in the Saudi market. We recommend Daikin and Mitsubishi Electric for their coastal corrosion resistance and long-term reliability in Saudi Arabia's climate.

Is the vacuum testing step really necessary?

Critical. Skipping vacuum testing is the most common shortcut taken by low-cost installers. A system with moisture in the refrigerant circuit develops acid sludge that destroys the compressor within 2–4 years. Proper vacuum removes all moisture. The 30-minute test adds 45 minutes to the job — it is essential insurance for the system's lifetime.
