System Types We Install

Wall-Mounted Split Systems

Multi-Split Systems – Several indoor units connected to a single outdoor condenser, providing flexible temperature control across multiple rooms. Ideal for homes or small businesses.

Capacity Range – 2 kW to 14 kW, suitable for spaces up to approximately 70m².

Ducted Air Conditioning

• Installed discreetly within ceiling voids for a hidden finish.
• Distributes air evenly through grilles or diffusers.
• Well-suited for open-plan homes, offices, and commercial settings.
• Options available for zoned temperature control using smart thermostats.

Ceiling Cassette Units

• Fitted flush within suspended ceilings for a neat, professional appearance.
• Four-way airflow ensures consistent cooling and heating.
• Ideal for offices, retail shops, classrooms, and hospitality venues.
• Available in both single and multi-split system configurations.

Floor-Mounted Units

• Positioned low on walls, similar in style to radiators.

VRV / VRF Systems (Variable Refrigerant Volume/Flow)

• High-performance systems designed for large-scale, multi-zone climate control.
• A single outdoor unit can support multiple indoor units (50+).
• Each zone can be individually controlled — allowing heating in one area and cooling in another simultaneously.
• Highly energy-efficient, with heat recovery options available.
• Best suited for large homes, hotels, office blocks, and retail complexes.

Air Conditioning Maintenance and Servicing

Air conditioning systems require annual servicing to maintain efficiency, comply with F-Gas regulations, and prevent costly breakdowns. Our maintenance contracts include:

• Filter cleaning and replacement
• Condenser and evaporator coil inspection and cleaning
• Refrigerant leak check and F-Gas documentation
• Electrical connections and controls check
• Performance testing — airflow, temperature differential, and operating pressures
• Report and certification issued after every service visit

Businesses with systems over 3kW have a legal obligation under F-Gas regulations to have them inspected regularly. Our service contracts keep you compliant.

Emergency Air Conditioning Repair in London

When commercial air conditioning fails during a London heatwave — or when a server room is overheating — downtime is not an option. Our 24/7 emergency line connects you with a qualified engineer who can diagnose and often fix the problem on the first visit.

Common faults we repair:

• AC not cooling — refrigerant low, compressor fault, or dirty condenser coil
• AC not heating (heat pump mode) — reversing valve failure or refrigerant issue
• Excessive noise — fan bearing wear, loose components, or debris in condenser
• Water leaking indoors — blocked condensate drain (very common in summer)
• System error codes — control board diagnosis and replacement
• Outdoor condenser fan failure — motor or capacitor replacement

Frequently Asked Questions — Commercial Air Conditioning London

Do I need F-Gas certification for my AC installation?
Yes. Any engineer working with refrigerants in the UK must be F-Gas certified. Xpress Refrigeration engineers are fully certified, ensuring your installation is legally compliant.

How long does a commercial AC installation take?
A single split unit typically takes 1–2 days. Multi-split or VRF systems may take 3–5 days depending on the number of indoor units and pipe run complexity.

What size AC system do I need?
This depends on room size, occupancy, heat-generating equipment, and window size/orientation. Our free site survey calculates the exact cooling load so you don’t end up with an undersized or oversized system.

Do you offer maintenance contracts for London businesses?
Yes. We offer annual and biannual maintenance contracts covering all F-Gas compliance requirements and performance checks. Contact us for a quote.
