How we handle commercial air conditioning in Sudbury
Many sites need more than cooling. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside, so the building works as a whole. The work covers wall-mounted split systems, ceiling cassettes and VRF systems, and the jobs we see most are new tenancies needing cooling and heating and IT rooms that need resilient cooling.
For a business in Sudbury, the legal side matters too: F-gas leak checks on larger systems, and TM44 inspections where total cooling output is over 12 kW. We keep the F-gas records and flag what’s coming up.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

How the visit works
We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. After that, it takes anything from a day or two for a small office to several weeks of phased work on a large building. The more we can see beforehand, the smoother the visit to Sudbury will be.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where needed.
- The system is commissioned and maintenance can be arranged.
Preparing for the visit
- Tell us about parking and loading
- Tell us about any building rules, permits or sign-in
- Let us know if the units are on a roof, a high wall or in a locked area
Ask for a quote
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Common problems we fix in Sudbury
Many businesses call us when an older system is struggling or failing. Parts become harder to find and the system cannot keep up, and replacing it becomes the better option.
Any of these is worth a proper look:
- Changes of use that need a new layout
- Workspaces that overheat on warm days
- Systems over 12 kW due a TM44 inspection
Before any plant goes outside a building like Church of St Andrew, its trustees may need planning or heritage advice, and we work with whoever gives it.
Comparing quotes
- What paperwork you will receive afterwards
- Who does the electrical work, and whether they can certify it
- Proof of F-Gas company certification

What else we do in Sudbury
Sudbury: your questions answered
Is Sudbury in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Sudbury is part of that. Just ring 07833 053749 or email us with a few details.
Can I have air conditioning in a flat in Sudbury?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do you carry out TM44 inspections?
The inspection itself must be done by an accredited energy assessor. What we do is prepare the system and carry out the improvements the report suggests.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Do you provide ongoing maintenance for businesses?
We do. A contract keeps the system serviced and any required leak checks on schedule, with records kept for each visit.
What owners can safely do
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
What air conditioning will not do
An honest diagnosis matters more to us than a booking, so here’s what commercial air conditioning won’t do:
- Fire safety design or fire risk assessments
- Structural alterations to the building
- Formal planning decisions, which rest with the council
Not sure which it is? You can call 07833 053749 or write to us at info@aircondoctor.co.uk and we will tell you honestly.

What commercial work looks like in Sudbury
There are about 157 restaurants, cafés and canteens, about 27 schools and colleges and about 68 care homes, nurseries and hospitals within roughly a mile and a half of the centre of Sudbury, according to the Food Standards Agency’s register. Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule. London commercial jobs typically involve a landlord or managing agent, and plant space is often tight.

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
