What happens on the day
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we have done and talk you through it. On site, the work takes a few days for a small shop or office, longer for VRF across several floors. Seeing the property in photos first helps us plan the trip to Leavesden.
- We survey the site and talk through how each area is used.
- You get our recommendation and a fixed price.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
Getting ready for the visit
- Tell us about parking and loading
- Have the make and model of any existing unit to hand
- Clear the space around the indoor unit, or where it will go

Commercial air conditioning for homes and businesses in Leavesden
Server rooms and comms rooms need cooling that keeps going. The design accounts for the equipment’s heat and can include a second unit as backup, so a single fault doesn’t leave the room without cooling. If you’re dealing with staff complaining about the temperature and older systems on refrigerants that are getting scarcer, we can sort it out.
Around Leavesden, commercial jobs are usually a shop, surgery, pub, office or workshop. Most need one to four indoor units, and we size them from a survey.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

What happens if it’s left?
An older system on R410A can be kept running, but top-up refrigerant is getting scarcer and dearer. It’s better to replace on your terms than after a breakdown. For a place like Leavesden, booking ahead lets us plan the visit properly.
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.

Aftercare tips
A little care keeps the system in better shape. We recommend:
- Report noises, leaks and faults early
- Show staff how to use the controls properly
- Leave space around outdoor units
Equipment warranties come from the manufacturer. We go through the manufacturer’s conditions with you and you will know what they ask for.
Simple control settings help. Units heating and cooling the same space at once is a common problem, and we can help set them up.

For landlords and property managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party and send the records to whoever needs them.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Leavesden questions
Will you come out to Leavesden?
Yes. Leavesden is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Do I need planning permission for air conditioning in Leavesden?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 3 buildings and structures within half a mile of the centre of Leavesden. 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 Three Rivers council, normally the authority for Leavesden.
Do you install in the evenings or at weekends?
We can. Work can be scheduled around your hours, including phased work floor by floor.
Do you offer commercial maintenance contracts?
Yes, with visits planned around the site. There’s also a 24/7 emergency line for breakdowns.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you carry out TM44 inspections?
We do not carry out the inspection itself, as it needs an accredited energy assessor. What we do is prepare the system and carry out the improvements the report suggests.
Can you come out in an emergency?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
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.”
