Residential Air Conditioning Installation Systems We Fit
Split System
Split systems are the most popular choice for our residential air conditioning installation customers needing 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.
All‑Season Heating & Cooling
Many modern systems provide both heating and cooling from the same unit, so you stay comfortable year-round without needing a separate heater. It’s an efficient, low-maintenance way to control your home’s temperature in every season.
AC Winter Heating
Compact, quiet system for corridors, clinics, treatment rooms and commercial spaces with limited wall space.
Heating/ Cooling for Garden Rooms
Compact, quiet system for corridors, clinics, treatment rooms and commercial spaces with limited wall space.

FAQs for Residential Air Conditioning Installations
How long does a residential AC installation take?
Most single‑room installations take 3–6 hours. Multi‑room or more complex setups may take 3-4 days. We confirm the exact timeframe during your free site survey.
Do I need planning permission to install air conditioning at home?
Most residential split systems fall under normal Permitted Development rights, so no planning permission is needed. If your home is in a conservation area, a listed building, or a leasehold flat with specific rules, we’ll check this for you during your free survey and help sort out any permissions needed.
How much does residential AC installation cost?
A single wall-mounted unit for a typical 30m²–35m² room starts from £2,600, depending on the brand you choose (Daikin, Mitsubishi, Toshiba, or Fujitsu) and how straightforward the installation is. You’ll always get a full written quote before any work begins.
Can you install AC in flats or apartments?
Yes — we regularly install AC in flats across London. We check outdoor unit placement, access, and any lease restrictions to ensure everything is compliant.
What type of AC system is best for my home?
For most homes, a wall‑mounted split system offers the best balance of performance, efficiency, and cost. Larger homes or open‑plan spaces may benefit from ducted or multi‑split systems. We recommend the ideal setup during your survey.
How noisy are modern AC units?
Modern indoor units run at 19–30 dB, which is quieter than a whisper. Outdoor units are also low‑noise and meet all UK residential noise regulations.
Will the installation cause any mess or damage?
No — we use dust sheets, protective coverings, and clean up thoroughly after installation. All drilling is done with dust extraction to keep your home tidy.
Do you offer warranties on residential installations?
Yes — all installations include a manufacturer warranty (typically 3 years) and our own installation workmanship guarantee for added peace of mind.
How energy‑efficient are the systems you install?
We install A++ and A+++ rated systems from trusted brands like Daikin, Mitsubishi, and LG. These systems use far less energy than portable AC units and provide more consistent cooling.
