Commercial air conditioning in Chandler's Cross, done properly
Commercial air conditioning comes with F-gas duties for the operator. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We carry out the checks, keep the records and tell you when the next one is due. If the problem is new tenancies needing cooling and heating and buildings that can’t close for the work, we can help.
For a business near Chandler's Cross, outdoor units usually have room at the back of the building.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Looking after it afterwards
After the visit, a few habits help:
- Note the 5-yearly TM44 date for systems over 12 kW
- Leave space around outdoor units
- Do not let servicing slip
Should anything seem off after handover, call 07833 053749 or send an email and we’ll come back to it. There’s a 24/7 emergency line for breakdowns.
Simple control settings help. Systems fighting each other, or set to extremes, waste effort and correct settings avoid it.
Before you call an engineer
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749 or drop us a line.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

FAQs for Chandler's Cross
Do you cover smaller places like Chandler's Cross?
Yes. Chandler's Cross is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Do I need planning permission for air conditioning in Chandler's Cross?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Chandler's Cross holds about 11 listed buildings and structures. 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 isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Chandler's Cross, typically Three Rivers council).
What does the operator have to do under the F-gas rules?
For systems at or above 5 tCO2e, the operator must have leak checks carried out and keep records. Checks are at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e and we carry out the checks and keep the records.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
What kind of air conditioning can you install in a business?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. We recommend the type that suits your space.
How we price commercial air conditioning
We quote each job individually. This is what makes a difference:
- Whether the existing supply is suitable
- The equipment or parts the job needs
- Whether it’s a one-off job or part of a maintenance contract
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
Asking for a quote
Photos and a few facts are often enough to price a simple job. Useful things to send:
- The postcode and whether it’s a home, flat or business
- The make and model of the system, from the label
- The paperwork from the last service, if you have it

A customer’s words
“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.”
