How we handle commercial air conditioning in Mill Corner
Commercial air conditioning comes with F-gas duties for the operator. Leak checks and records are required for systems from 5 tCO2e upwards. We carry out the checks, keep the records and tell you when the next one is due. The work covers ducted systems, wall-mounted split systems and VRF systems, and the jobs we see most are server rooms running too warm and F-gas leak checks and records that are overdue.
If you run a village hall or similar building near Mill Corner, heating and cooling that warms up fast suits a space used on and off, and it can heat as well as cool.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Common problems we fix in Mill Corner
When a space is refitted or its use changes, the old layout may no longer work. More people, new walls or extra equipment alter what the system has to cope with, and the system has to match.
Common reasons people call us include:
- Systems over 12 kW due a TM44 inspection
- Changes of use that need a new layout
- Missing F-gas records for commercial systems
Above 12 kW of effective rated output, an accredited energy assessor has to inspect the system at least every five years.

VRF and VRV systems
Larger systems carry more refrigerant so leak checks and records often apply. We work out the tCO2e and set the check schedule.
F-gas records and TM44
An accredited energy assessor carries out the TM44 inspection. We’re not assessors, but we prepare the system and carry out the improvements the report recommends.
How it works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill.

Questions from Mill Corner
Will air conditioning in Mill Corner need planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Mill Corner is in a conservation area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not 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 Rother council, usually the authority for Mill Corner.
Will you come out to Mill Corner?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
How much time does a commercial air con install need?
A typical installation takes anything from a day or two for a small office to several weeks of phased work on a large building. Phased or out-of-hours work may extend it though it keeps disruption down.
Why act early in Mill Corner
A system that can’t cope on the hottest days affects everyone in the building. Planning a replacement or upgrade before the summer is easier than reacting in a heatwave. Getting the date in early helps for a place like Mill Corner.
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before we start, so there are no surprises.
