What a Air Conditioning Installer Job Typically Involves
A standard air conditioning installer quote usually covers:
Labour for supply and installation of the agreed split or multi-split system, including indoor unit(s), outdoor condenser, and interconnecting pipework
Refrigerant pipework, control cabling, condensate drainage, and core drilling through the wall for a standard run
Evacuation, vacuum testing, and charging of the refrigerant circuit by an F-Gas certified engineer
Commissioning, performance testing, and a handover briefing on controls, modes, and filter cleaning
An F-Gas installation record and manufacturer warranty registration (typically 5–7 years subject to annual servicing)
Cleaning the filters, keeping the outdoor condenser clear of leaves, and operating the controls is the full extent of safe DIY with air conditioning. Installation, repair, and even recharging must be done by an F-Gas certified engineer, because handling fluorinated refrigerants without certification is illegal under the F-Gas Regulations, and the gases are harmful to release, held under high pressure, and dangerous to charge incorrectly. The electrical connection is also notifiable Part P work, so use an installer who is both F-Gas (Refcom) registered and works with a registered electrician — cheap 'plug-in' multi-split fittings advertised for DIY are not a substitute for a properly evacuated, leak-tested system.

Use the official Refcom (Register of Companies Competent to Handle Refrigerants) checker to verify registration in seconds. Ask the tradesperson to produce qualification certificates, public liability insurance documents, and any relevant accreditation before work begins. A trustworthy professional will have these documents readily available.
A deposit of 10–20% is normal practice for larger air conditioning installer jobs. Never pay more than 25% upfront, and always pay by card or bank transfer rather than cash so you have a clear payment record. Avoid any tradesperson who demands full payment before starting.
Warning signs include: demands for a large cash deposit before any work starts, inability to produce insurance or qualification proof, refusal to provide a written quote, significantly undercutting all other estimates, and pressuring you to decide immediately. A reputable air conditioning installer will never rush you.
Use vetted platforms such as Checkatrade, Rated People or TrustMark to find reviewed air conditioning installers in your area. Personal recommendations from neighbours or friends remain the most reliable method. Always verify public liability insurance of at least £1 million before agreeing to any work.
