VRF/VRV systems for commercial properties
We’re approved installers for leading brands such as Daikin, Mitsubishi Electric, and Samsung.
What areas do you cover?
We provide air conditioning installation, servicing, and maintenance across London, Buckinghamshire, Hertfordshire, and surrounding areas. If you’re unsure whether we cover your location, contact us and we’ll confirm right away.
Do you offer free quotes?
Yes — we provide free, no-obligation quotations. Our quotes include full equipment specifications, installation details, and optional maintenance plans.
How often should my air conditioning system be serviced?
We recommend servicing your air conditioning every 6 months (typically before summer and winter) to ensure peak performance, energy efficiency, and warranty compliance.
Can you service or repair systems you didn’t install?
Absolutely. Our engineers can service, fault-find, and repair any air conditioning brand or model, even if it wasn’t installed by us.
Do you offer maintenance contracts?
Yes, we offer bespoke maintenance plans for both domestic and commercial clients. These include priority call-outs, discounted repairs, and regular performance checks.
How much does air conditioning cost to install in the UK?
The cost of air conditioning installation depends on the size of your space, system type, and brand. On average, domestic installations start from around £1,700, while multi-room or ducted systems can range from £2,500–£7,000+. We offer free on-site surveys and detailed quotes to give you an accurate price before any work begins.
What size air conditioner do I need for my room?
The correct AC size depends on your room dimensions, insulation, number of windows, and heat-producing appliances. Our engineers calculate the exact cooling capacity (in kW) needed to keep your room comfortable and energy efficient — no guesswork involved.
Can air conditioning heat my home in winter?
Yes — all modern air conditioning systems are heat pumps, meaning they can both cool and heat your property efficiently. This makes them a great all-year-round solution for comfort and lower energy bills compared to traditional heating systems.
Are air conditioning units noisy?
Modern air conditioning systems are designed to be ultra-quiet, especially when installed correctly. Indoor units typically operate between 19–30 decibels (quieter than a whisper), while outdoor units are placed strategically to minimise any disturbance.
