Commercial air conditioning in Carshalton, done properly
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out. We do not carry out the inspection itself, but we prepare the system and do the work it recommends. If the problem is buildings that can’t close for the work and older systems that can’t keep up, we can sort it out.
London buildings in Carshalton can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems keep outdoor plant down by serving many rooms from few outdoor units.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

How we price commercial air conditioning
We quote each job individually. This is what makes a difference:
- One-off work versus a regular service cycle
- The equipment or parts the job needs
- What kind of system it is
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are not sure what’s needed, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk for straight advice and a fixed price.
Asking for a quote
When you call or email, it’s useful to have:
- Where the outdoor unit is, or where you’d like it
- The fuse board and where it is in the property
- Your installation or service records
To get a fixed-price quote, call 07833 053749 or send an email with the address and a few details about the rooms or units involved. A few pictures make it quicker. You will hear back from us the same working day.
Honest limits
Some problems need a different service or another trade:
- Plumbing beyond the condensate drainage
- Acting as the energy assessor
- Fire strategy sign-off
If in doubt, phone 07833 053749 or send an email and we will say what we think.
Where we work
- Server and comms room cooling
- Multi-split systems
- Wall-mounted split systems
- VRF systems
- Ceiling cassettes
- Ducted systems
Looking after your system
To keep the system working properly:
- Leave space around outdoor units
- Book a maintenance contract to keep servicing on schedule
- Note the 5-yearly TM44 date for systems over 12 kW
If the system needs F-gas leak checks, we diary the first one and can include it in a maintenance contract.
Plan replacements before old systems fail, particularly where they use R410A.

The process
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Send us a few phone pictures and we can often price a straightforward job in Carshalton before visiting.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- Installation is scheduled to fit the business, with out-of-hours and phased work where needed.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Before we arrive
- Make sure someone can let us in at the agreed time
- Make sure we can reach the outdoor unit, or where it will go
- Tell us about parking and loading

Carshalton: your questions answered
Do you cover Carshalton for commercial air conditioning?
We do: Carshalton falls inside our working area. Get in touch with the details and we reply the same working day.
Will air conditioning in Carshalton need planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Carshalton sits inside a conservation area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the planning department at Sutton council, normally the authority for Carshalton.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
Are you TM44 assessors?
We do not carry out the inspection itself, as it needs an accredited energy assessor. Our part is getting the system ready and doing the follow-up work.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
What does the operator have to do under the F-gas rules?
Operators of systems from 5 tCO2e upwards need leak checks and records. The intervals are at least yearly from 5 to under 50 tCO2e, and 6-monthly from 50 to under 500 tCO2e, and we can handle both.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
