Choosing the right capacity is the most important decision before buying a split AC. In Asir Region, this is more complex than in other areas due to the altitude factor.

BTU Calculation for Abha — The Altitude Equation

Standard BTU calculations are based on room area and outdoor temperature. In Abha, we add an altitude correction factor (~10% capacity increase) because actual cooling efficiency is lower at 2,200m. A 20 sqm room in Abha needs a higher-capacity unit than the same room size in Riyadh.

Split AC Installation Steps

  • Determine optimal indoor unit location (airflow, ceiling clearance, away from direct heat)
  • Drill correctly-sized passage hole for pipe routing
  • Securely mount indoor unit bracket on wall
  • Connect refrigerant and drain pipes with correct insulation
  • Install outdoor unit on bracket or slab with adequate ventilation clearance
  • Connect electrical supply and control wiring
  • Pull system vacuum before refrigerant charge
  • Charge refrigerant and adjust pressure per manufacturer spec and altitude
  • Full operation test and cooling efficiency measurement

Common Installation Mistakes to Avoid

  • Do not mount the outdoor unit in an enclosed or tight space — it needs full ventilation clearance on all sides for condenser airflow. A unit hemmed in by walls will overheat and fail early
  • Do not route refrigerant pipes through sharp bends — this restricts refrigerant flow and reduces efficiency from day one
  • In Jazan, apply corrosion-resistant coating to all outdoor pipe connections before installation — salt air attacks copper joints and weakens brazed connections over time
  • Do not install the outdoor unit on an exposed south-facing rooftop in Abha without shade — direct midday sun raises condenser temperature and measurably reduces cooling output
  • Do not skip the vacuum pull before charging refrigerant — any moisture left in the circuit damages the compressor within one season, especially in Jazan's humid conditions
  • Do not leave the pipe penetration hole unsealed — it allows insects, humidity and hot outside air to enter, critically important in Jazan where outdoor humidity is 80%+

AC Relocation — Moving Your Unit to a New Position

Moving an AC from one room to another, or changing its position within a room, is a common service during renovation or reconfiguration. The difference from new installation: existing refrigerant lines must be properly recovered before disassembly, and new pipe runs may be needed if the distance changes.

What Differs in AC Relocation vs New Installation

1. Refrigerant recovery before disassembly — gas must not be released to atmosphere (illegal and environmentally harmful). 2. Both units cleaned before reinstallation at the new location. 3. Existing pipes inspected for damage caused by disassembly. 4. Full recharge after installation with pressure adjusted for altitude in Abha's case.

In Abha, moving the outdoor unit from an exposed rooftop position to a shaded wall location meaningfully improves summer performance. We specifically recommend this for outdoor units exposed to direct south-facing sun in Abha and Khamis Mushait — the heat load reduction on the condenser can be significant.

Frequently Asked Questions

Which split AC brand is best for the region?
There is no single 'best' brand — the choice depends on budget, room size, and local parts availability. Samsung, LG, and Gree have the widest regional service coverage.
Can split AC installation be done in one day?
Yes — standard single-unit installation takes 3–5 hours. Multiple units can be completed in one day with an expanded team.
Does the installation warranty cover wall penetrations?
Yes — drilling and pipe routing are under our warranty. We will repair any damage to walls that occurs during installation.
