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 a full day. We confirm the exact timeframe during your free site survey.
Do I need planning permission to install air conditioning at home?
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.
How much does residential AC installation cost?
A single premium wall-mounted unit installation for a typical 30m² – 35m² room typically starting from £2,600 depending entirely on your chosen component tier (Daikin, Mitsubishi, Toshiba, or Fujitsu) and path routing variables. All estimations are completely finalized in writing beforehand.
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.
