Commercial air conditioning for homes and businesses in St Leonards
We design, install and look after air conditioning for businesses in St Leonards and across Hertfordshire. Offices, shops, restaurants, hotels, schools and server rooms all come with different demands and we choose the system to suit the space and the way it’s used.

What owners can safely do
On air conditioning, the filters in the indoor unit are usually 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.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
St Leonards questions
Can you do commercial air conditioning in St Leonards?
Yes. We work across London and the South East from our base in East Grinstead, and St Leonards is part of that. Just call us on 07833 053749 or email us with a few details.
Will you come out to St Leonards?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Will you make a mess?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Will I get records for the system?
Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
How does the warranty work?
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.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book and we’ll gladly show you ours.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in St Leonards and across Hertfordshire. Tell us who should receive the paperwork.
Different systems, different jobs
Ceiling cassettes
Cassettes sit in the ceiling and blow air in several directions. They’re common in offices, retail and dining areas with suspended ceilings.
Offices
Offices gain heat from occupants, equipment and the sun. We size the system for the actual heat load and choose units that suit the ceiling and layout.
What commercial work looks like in St Leonards
About 31 miles out from central London, St Leonards is part of the South East area we work across. Church of St Leonard, listed at grade II*, is one of roughly 3 protected buildings and structures in the half-mile around St Leonards’s centre. If your property is listed or sits inside a conservation area, expect us to raise planning at the survey and to speak to the local planning authority (usually Buckinghamshire council) where it’s needed.
Churches and halls such as Church of St Leonard 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. Healthcare premises near Chiltern Hospital need air conditioning that’s easy to clean and maintained on a schedule.

Leave it or put it right?
An older system on R410A can be kept running, but top-up refrigerant is getting scarcer and dearer. Planning a replacement on your own timetable beats replacing it after a major failure. Dealing with it now is normally simpler than a breakdown later.
