Commercial air conditioning in Cannon's Green, done properly
Many sites need more than cooling. Air conditioning systems can heat as well as cool, and we also install ventilation and MVHR for a joined-up system. Common call-outs are for commercial systems near the end of their life and systems over 12 kW due a TM44 inspection, across ceiling cassettes, server and comms room cooling and wall-mounted split systems.
Around Cannon's Green, there’s usually space for outdoor plant away from the road, out of sight and away from neighbours.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

For a place like Cannon's Green, the timing is set with you and the travel is our side of the planning.
- We start with the details of the building and the problem.
- 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 necessary.
- The system is commissioned and maintenance can be arranged.

Cannon's Green: your questions answered
Will you come out to Cannon's Green?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do I need planning permission for air conditioning in Cannon's Green?
It depends on the property. Historic England lists about 19 buildings and structures within half a mile of the centre of Cannon's Green. 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 Epping Forest council, which is typically the planning authority for Cannon's Green when it matters.
How much time does a commercial air con install need?
As a guide, it takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. Out-of-hours and phased work can spread the programme but keeps the business running.
Can you look after our air conditioning after it’s installed?
Yes, and we tailor the schedule to the system and how hard it works. For breakdowns, there’s a 24/7 emergency line.
Why does F-Gas certification matter?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and we hold it.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Can you do our TM44 air conditioning inspection?
We are not accredited energy assessors, so we do not inspect. We help before and after, preparing the system and acting on the report.

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
