• Outdoor unit positioning on brackets or concrete base
• Refrigerant pipe and electrical cable routing
• Vacuum testing and refrigerant charging
• System commissioning and performance testing
• User training and handover documentation

Single split system installation typically takes 4-6 hours, whilst multi-split systems may require 1-2 days. Ducted systems often need 3-5 days depending on property size and complexity.

Cost Breakdown and Pricing Factors

Air conditioning installation costs vary significantly based on multiple factors. Understanding these variables helps budget effectively and avoid unexpected expenses.

Equipment Costs represent 40-60% of total installation expenses. Premium brands like Mitsubishi, Daikin, and Panasonic command higher prices but offer superior efficiency and reliability. Budget brands may save £200-£500 initially but could incur higher running costs and shorter lifespans.

Labour and Installation Charges typically range from £500 to £1,500 per unit, influenced by installation complexity, access difficulties, and regional variations. Edinburgh installers generally charge £40-£60 per hour, with most installations requiring two engineers for safety and efficiency.

Additional Cost Considerations often overlooked during initial budgeting:

• Electrical upgrades: £300-£800 for dedicated circuits
• Condensate pumps: £150-£300 where gravity drainage isn’t possible
• Extended warranty packages: £200-£500 for 5-year coverage
• Annual maintenance contracts: £150-£300 per year
• Planning permission applications: £206 for householder applications
• Scaffolding for difficult access: £500-£1,500

Regional price variations exist across the UK, with London installations typically 20-30% higher than Scottish cities like Edinburgh. However, Edinburgh’s competitive market often provides better value than smaller Scottish towns with limited installer availability.

Choosing Qualified Air Conditioning Installers

Selecting competent installers ensures safe, efficient installation and ongoing system reliability. Several key credentials and considerations guide this crucial decision.

Essential Qualifications and Certifications distinguish professional installers from unqualified operators. F-Gas certification is legally required for anyone handling refrigerants, with installers displaying their registration number. REFCOM registration indicates company-level compliance with F-Gas regulations. Additional valuable certifications include Safe Contractor approval, CHAS accreditation, and manufacturer-specific training certificates.

Questions to Ask Potential Installers help assess competence and professionalism:

• Can you provide F-Gas and REFCOM certificates?
• Do you carry public liability insurance of at least £2 million?
• Will you handle Building Control notifications?
• Can you provide recent references from Edinburgh properties?
• What warranty terms do you offer on equipment and labour?
• Do you provide emergency call-out services post-installation?

Red Flags to Avoid include cash-only payments, reluctance to provide written quotations, pressure tactics demanding immediate decisions, and unusually low prices suggesting corner-cutting. Legitimate installers welcome questions and provide comprehensive documentation.

Energy Efficiency and Running Costs

Modern air conditioning systems offer impressive energy efficiency, but understanding ratings and optimising usage remains crucial for controlling running costs.

Understanding Energy Ratings helps select efficient systems. The SEER rating measures cooling efficiency, with higher numbers indicating better performance.
