Commercial air conditioning in Potters Bar, done properly
Heating, cooling and fresh air often go together. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside, so the building works as a whole. Common call-outs are for older systems on refrigerants that are getting scarcer and F-gas leak checks and records that are overdue, across VRF systems, server and comms room cooling and wall-mounted split systems.
Commercial installs in Potters Bar are planned to keep you trading, often over a weekend or a few evenings.
The records are your 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.

What else we do in Potters Bar
What the work involves, system by system
Hotels and schools
Schools often need installs during the holidays, with the programme agreed well in advance.
Ceiling cassettes
Installing a cassette needs room in the void and a way to drain the water. Many have a built-in pump to lift the condensate, which we check on every service.
Looking after it afterwards
Simple habits make a real difference. Our advice:
- Keep outdoor units clear of rubbish and stored goods
- File every leak check and service record in one place
- Tell us early about fit-outs or changes of use
We show your team how to use the controls so staff can set it up properly. Simple settings make a real difference to comfort and running.
Keep filters clean and plant areas clear. Restricted airflow puts strain on the whole system.
How it works
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, check the system and explain it all to you. On site, the work takes a few days for a small shop or office, longer for VRF across several floors. In a town like Potters Bar, we fit the visit around you.
- 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.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Find the manual or the paperwork for the system, if you have it
Getting a quote
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

FAQs for Potters Bar
Can you do commercial air conditioning in Potters Bar?
Yes. We work across London and the South East from our base in East Grinstead, and Potters Bar is part of that. Tell us a little about the job and we’ll take it from there.
Is air conditioning in Potters Bar permitted development?
It depends on the property. Historic England lists about 9 buildings and structures within half a mile of the centre of Potters Bar. 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 Hertsmere council, which is normally the planning authority for Potters Bar.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Do you look at the job first?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Do you carry out TM44 inspections?
The inspection itself must be done by an accredited energy assessor. Our part is getting the system ready and doing the follow-up work.
What does the operator have to do under the F-gas rules?
The duties depend on how much refrigerant the system holds. Systems at or above 5 tCO2e need leak checks and records with automatic leak detection at 500 tCO2e and above.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
