Tpyical AC Systems We Install
Split System
Split systems are the most popular choice for single‑room cooling and heating, offering quiet operation, low running costs and fast installation. Ideal for bedrooms, living rooms, home offices, treatment rooms, small offices and retail spaces, they deliver powerful climate control with minimal disruption and excellent energy efficiency.
Multi-Split System
Multi‑split systems allow you to cool and heat several rooms using one outdoor unit, making them ideal for homes, apartments, salons, clinics, and small commercial spaces with limited exterior wall space. Each indoor unit can be controlled independently, giving you personalised comfort in every room while keeping installation tidy and energy‑efficient. Perfect for properties where flexibility, zoning, and quiet performance are essential.
Ceiling Systems
Ceiling Cassette
Ceiling cassette systems deliver powerful, evenly distributed airflow through a discreet 4‑way outlet, making them perfect for shops, offices, salons, cafés and commercial spaces. Installed flush within a suspended ceiling, they provide high‑performance cooling and heating without taking up wall space, offering quiet operation, excellent coverage and a premium, modern finish.
Suspended Cassette
Suspended cassette systems are designed for commercial environments with high ceilings, limited ceiling voids, or open‑plan layouts where traditional ceiling cassettes cannot be installed. These units deliver powerful airflow, wide coverage and excellent cooling performance, making them ideal for warehouses, workshops, gyms, retail units and large commercial spaces. Their robust design ensures reliable operation even in demanding conditions, while maintaining efficient, evenly distributed climate control.

FAQs for Air Conditioning Installations
How long does an air conditioning installation take?
Most standard wall‑mounted AC installations take 3–6 hours. Larger systems, multi‑room setups, or commercial installations may take a full day. We always confirm the exact timeframe during your free site survey
Do I need planning permission for Air Conditioning Installation in my property?
The vast majority of residential split configurations operate within regular Permitted Development structures. However, spaces situated within historical conservation zones, listed locations, or specific leasehold terms require customized authorizations. Our surveyors assist in analyzing structural guidelines cleanly.
What type of AC system is best for my home or business?
For most properties, a wall‑mounted split system is the best balance of cost, efficiency, and performance. Offices and commercial spaces often benefit from cassette or ducted systems. We recommend the ideal system based on room size, layout, and budget.
How much does air conditioning installation cost?
Prices vary depending on the system type, room size, and installation complexity. Most single‑room installations start from £2,400 including supply and installation. We provide fixed, upfront quotes with no hidden fees.
Do you offer a warranty on installations?
Yes — all installations come with a manufacturer warranty (usually 3–5 years) and our own installation workmanship guarantee. We only install trusted brands like Daikin, Mitsubishi, and LG.
Do you remove old or existing AC units?
Yes — we can safely remove and dispose of old AC systems, including refrigerant handling, in line with F‑Gas regulations.
