Commercial AC Installation London

Commercial Air Conditioning Installation for London Businesses

London AC Pro delivers professional commercial air conditioning solutions for businesses of all sizes across the capital. From independent retail shops and restaurants to large office buildings, hotel chains and healthcare facilities, our F-Gas certified and REFCOM Elite registered team (company reg 15526897) designs and installs commercial AC systems that keep your staff comfortable, your customers satisfied and your energy bills under control. We work with industry-leading brands including Daikin, Mitsubishi Electric, Samsung, LG, Fujitsu and Toshiba to deliver reliable, energy-efficient climate control tailored to your commercial requirements.

Effective commercial air conditioning is about far more than comfort. It directly impacts staff productivity, customer experience, regulatory compliance and operational costs. Studies consistently show that office workers are up to 15% less productive when indoor temperatures exceed 25°C. For restaurants, hotels and retail environments, temperature and air quality are critical to the customer experience and can directly affect revenue. Our commercial installations are engineered to deliver consistent, reliable climate control while minimising running costs and meeting all regulatory requirements.

Industries and Sectors We Serve

Our commercial air conditioning expertise spans a wide range of sectors. We understand that every business has unique requirements, and we tailor our approach accordingly:

Offices and Corporate Buildings

We install air conditioning for offices of every size, from single-room serviced offices to multi-floor corporate headquarters. Our office installations focus on consistent temperature control across open-plan areas and individual offices, quiet operation to avoid disrupting work, and integration with Building Management Systems (BMS) where required. VRF systems from Daikin and Mitsubishi Electric are the preferred choice for larger offices, while wall-mounted and cassette units serve smaller office spaces effectively.

Hotels and Hospitality

Guest comfort is paramount in hospitality. We design and install AC systems for hotel bedrooms, reception areas, restaurants, conference rooms and back-of-house areas. Our hotel installations feature individually controllable room units, quiet operation for guest comfort, centralised control and monitoring, and energy management to minimise costs across large room counts.

Restaurants, Cafes and Commercial Kitchens

Restaurants present unique air conditioning challenges. Kitchen extract systems, high occupancy levels, cooking heat and frequent door openings all increase the cooling load. We design restaurant AC systems that maintain comfortable dining temperatures despite these challenges, using high-capacity cassette and ducted systems that cope with variable heat loads. We also install kitchen ventilation and extract systems as part of a complete climate control package.

Retail and Shops

A comfortable shopping environment encourages customers to stay longer and spend more. We install air conditioning for high-street shops, shopping centres, showrooms and supermarkets. Ceiling cassette units from Samsung and Daikin are particularly popular in retail environments, providing even air distribution while sitting discreetly flush in ceiling tiles.

Healthcare and Medical Facilities

Clinics, dental practices, GP surgeries and private healthcare facilities require reliable temperature control and excellent air quality. We install systems with enhanced filtration and precise temperature control to meet healthcare standards.

Gyms, Leisure and Fitness Centres

Gyms and fitness facilities generate significant internal heat from exercise equipment and high occupancy. We design high-capacity systems that maintain comfortable training temperatures even during peak hours.

Server Rooms and Data Centres

IT equipment generates substantial heat and requires precise, reliable cooling to prevent damage and downtime. We install dedicated server room cooling systems with redundancy, monitoring and alerting capabilities. For businesses where server room cooling is mission-critical, we offer systems with N+1 redundancy and remote monitoring.

Education and Schools

Classrooms and lecture halls benefit significantly from air conditioning, improving concentration and learning outcomes during warm months. We work with schools, colleges and universities to deliver cost-effective cooling that can be funded within education budgets.

Commercial AC System Types

We install the full range of commercial air conditioning systems, selecting the best technology for each application:

• VRF/VRV systems — Variable Refrigerant Flow technology is the gold standard for medium to large commercial buildings. A single outdoor unit serves multiple indoor units across different zones, each independently controlled. Daikin VRV and Mitsubishi Electric City Multi are the market-leading VRF platforms, offering simultaneous heating and cooling (heat recovery), advanced energy management and integration with BMS systems. VRF is ideal for offices, hotels and multi-tenanted buildings.
• Ceiling cassette units — flush-mounted in standard 600x600mm ceiling tiles, cassettes distribute air evenly in four directions and are the most popular choice for offices, retail and hospitality. Samsung, Daikin and Mitsubishi Electric all offer compact, efficient cassette units.
• Ducted systems — concealed above the ceiling with air delivered through linear or square diffusers. Ducted systems offer a completely clean aesthetic with no visible equipment in the occupied space. They are ideal for premium offices, hotel corridors and retail showrooms.
• Wall-mounted units — a cost-effective solution for individual rooms, small offices, consulting rooms and server rooms. Quick to install with minimal disruption.
• Floor-standing and under-ceiling units — powerful units for large spaces, server rooms, warehouses and areas where ceiling installation is not practical.

Part L Compliance and Building Regulations

All commercial air conditioning installations must comply with Part L of the Building Regulations, which sets minimum energy efficiency standards for building services. Our installations are fully compliant and we provide all necessary documentation including commissioning certificates and building control notifications. For systems over 12 kW, we also ensure compliance with TM44 Energy Performance of Air Conditioning inspection requirements. Our team can assist with system design that meets Part L from the outset, avoiding costly modifications later.

Planned Preventative Maintenance (PPM) for Commercial Systems

Commercial air conditioning systems work harder and longer than residential units, making regular maintenance essential. We offer tailored Planned Preventative Maintenance contracts that include scheduled service visits (quarterly, bi-annual or annual), filter cleaning and replacement, refrigerant level monitoring, electrical safety checks, performance reports and recommendations, priority emergency callout, and discounted repair rates. PPM contracts ensure regulatory compliance, maximise system efficiency, reduce energy costs and minimise the risk of unexpected breakdowns that disrupt your business. Visit our maintenance page for full details of our commercial maintenance plans.

Minimising Disruption to Your Business

We understand that commercial installations must work around your business operations. Our project management approach includes detailed scheduling to minimise disruption, out-of-hours and weekend installation available, phased installation for occupied buildings, clean and tidy working practices, regular progress updates to your nominated contact, and full site-specific risk assessments and method statements. For multi-site businesses such as restaurant chains, hotel groups and retail portfolios, we offer a dedicated project manager to coordinate installations across all locations.

Frequently Asked Questions About Commercial AC Installation

How long does a commercial AC installation take?

Timelines vary depending on the system type and building size. A small office with two or three wall-mounted or cassette units can be completed in one to two days. A VRF installation for a multi-floor office typically takes one to three weeks. Restaurant and hotel installations are scheduled around operational hours to minimise disruption. We provide a detailed programme with your quotation.

Do I need to notify Building Control about a commercial AC installation?

Yes. Commercial air conditioning installations must be notified to Building Control under Part L of the Building Regulations. As an approved installer, we handle this notification on your behalf and provide all required commissioning certificates and compliance documentation.

What is a TM44 inspection and do I need one?

TM44 refers to CIBSE Technical Memorandum 44, which sets out requirements for the energy assessment of air conditioning systems over 12 kW. Buildings with AC systems above this threshold must have a TM44 inspection every five years. We can carry out TM44 inspections and provide the required Energy Performance Certificate for your air conditioning system.

Can you install air conditioning outside of business hours?

Yes. We routinely carry out commercial installations during evenings, weekends and overnight to minimise disruption. Out-of-hours work is quoted separately and scheduled to suit your operational requirements.

Do you offer maintenance contracts for commercial AC?

Yes. We offer comprehensive Planned Preventative Maintenance contracts tailored to your system and business requirements. PPM contracts include scheduled service visits, priority emergency response, discounted repair rates and detailed performance reporting. Contact us on 07301 010244 or visit our maintenance page for details.
