Commercial air conditioning in Charlton, done properly
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor; we are not assessors, but we prepare systems for inspection and act on what the report finds. The work covers multi-split systems, ceiling cassettes and wall-mounted split systems, and people most often call us about leak check schedules that have slipped and server rooms running too warm.
If you run a village hall or similar building near Charlton, heating and cooling that warms up fast suits a space used on and off.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

When to call us in Charlton
Older systems running on R410A face rising costs for top-ups as the GB HFC phase-down tightens supply. Servicing and repairing R410A systems is still allowed, but it’s a factor when planning a replacement.
These are the situations we see most often:
- Workspaces that overheat on warm days
- Work raised by a TM44 inspection
- Buildings that can’t close for the work
Churches and halls such as The Parish Church of the Blessed Virgin Mary are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.

What affects the quote in Charlton
Every job gets its own quote. This is what makes a difference:
- What kind of system it is
- How many units are involved
- A single visit or a regular plan
What you pay depends on the system and the number of rooms or units, the access and what the work involves. We give you a fixed price before work begins, so there are no surprises.
Before you get in touch
Photos let us diagnose from a distance. The most useful are:
- The make and model of the system, from the label
- Photos showing the indoor unit and the space around it
- Where the outdoor unit is, or where you’d like it
For commercial air conditioning in Charlton, phone 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 photos if they’re to hand. We reply the same working day.

How the visit works
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes from a couple of days for a few cassettes to a planned programme for a whole building. Somewhere like Charlton, it helps to know about lanes, gates and where to park.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- We set out the options, the price and the programme.
- We install around your hours, phased where necessary.
- The system is commissioned and maintenance can be arranged.
Getting ready for the visit
- Keep pets and children away from the work area
- Find the manual or the paperwork for the system, if you have it
- Mention any roof access, ladders or high-level work
How to get a quote

Your questions about commercial air conditioning in Charlton
Do you cover Charlton for commercial air conditioning?
Yes. Charlton is one of the places we cover. Just ring us on 07833 053749, or email if that’s easier with a few details.
Can I fit air conditioning in Charlton without planning permission?
That depends on the building and where the outdoor unit goes. The Charlton Conservation Area takes in the middle of Charlton. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Charlton, usually Chichester council) when it matters.
Can you install out of hours?
Yes, timing is agreed to suit you. Shops, offices, restaurants and schools all have different needs and the plan reflects it.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are also Checkatrade members.
Do you offer commercial maintenance contracts?
Yes, with visits planned around the site. For breakdowns, there’s a 24/7 emergency line.
Do I need to service the system to keep the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Leave it or put it right?
An older system on R410A can be kept running, but top-up refrigerant is getting scarcer and dearer. It’s better to replace on your terms than after a breakdown. Dealing with it now is typically simpler than a breakdown later.
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote, and the price is fixed before we start.
