- Missing F-gas records for commercial systems
- Staff complaining about the temperature
- Older systems that can’t keep up
How the visit works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes from a couple of days for a few cassettes to a planned programme for a whole building. Some blocks in Cranford need contractor details in advance, so tell us what your building needs.
- First comes a survey, looking at the building and how it’s occupied.
- We recommend a system and send a fixed-price quote.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
Preparing for the visit
- Let us know if the building has a permit or sign-in process
- Let us know where the consumer unit is
- Arrange for someone to be there to let us in
Getting a price
Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

How we handle commercial air conditioning in Cranford
The business that operates the system has F-gas responsibilities. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We carry out the checks, keep the records and tell you when the next one is due. The work covers server and comms room cooling, wall-mounted split systems and multi-split systems, and people most often call us about ageing air conditioning that keeps breaking down and changes of use that need a new layout.
In a London area like Cranford, commercial air conditioning goes into offices, shops, restaurants and server rooms, often in shared buildings. So landlord consent, plant positions and noise all need agreeing first, and installs are often done out of hours.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What else we do in Cranford
Different systems, different jobs
Ceiling cassettes
A cassette needs space above the ceiling and a route for the condensate. Many include a pump to move the water away and that’s checked when it’s serviced.
Server and comms rooms
Server room systems need regular servicing to stay reliable and we can cover it under a contract.
Questions from Cranford
Do I need planning permission for air conditioning in Cranford?
That depends on the building and where the outdoor unit goes. The Cranford Village Conservation Area is close to the centre of Cranford. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Hounslow council, normally the authority for Cranford.
Do you cover Cranford for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Cranford is part of that. To start, call 07833 053749, or email if that’s easier with a few photos.
Do I need to service the system to keep the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we will tell you what your brand asks for.
How quickly will you reply?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
How much time does a commercial air con install need?
It takes a few days for a small shop or office, longer for VRF across several floors. The scale and programme decide most of it, and we set out the timing with your quote.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
How often is a TM44 inspection needed?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. An accredited energy assessor does the inspection, and we can carry out the recommended work.
What affects the quote in Cranford
The survey or diagnosis tells us what the work involves. The main factors are:
- The distance and route between the indoor and outdoor units
- The type of system, from a single split to a larger system
- The equipment or parts the job needs
Height, access and the distance between the indoor and outdoor units all affect the cost. We take each of them into account, and the price is fixed before any work starts.
What to send for a quote
When you call or email, it’s useful to have:
- A close-up of the unit’s label showing the model number
- Wide photos of the room or the existing unit
- The outdoor side of the property, including any roof or flat area
If you need commercial air conditioning in Cranford, call us on 07833 053749 or drop us a line. Tell us what kind of property it is and what you’d like done, plus some pictures if they’re to hand. We reply the same working day.
