Air conditioning in AL5: how it works
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and our NICEIC approval means we install and certify it ourselves. The work covers VRF systems, multi-split systems and ducted systems, and common reasons people get in touch are commercial rooms that are too warm for staff and not knowing which system, size or brand to choose.
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
What you will pay
Height, access and the distance between the indoor and outdoor units can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Where we install in AL5
Across AL5, from Harpenden, Batford and Kinsbourne Green to the villages, homes range from older terraces and cottages to new estates and flats. We survey every property before we quote.
An F-Gas certified company does the refrigerant side, and the electrics come under our NICEIC approval.
Harpenden: Plenty of people near Harpenden station split the week between the train and a spare room, and that spare room is often the first to get a unit. About 2.6 miles south stands Childwickbury Manor. Listed homes in any area need consent first, so tell us if yours is one.
Managing agents and facilities teams in AL5
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
What the work involves, system by system
Ducted systems
A ducted system needs a ceiling void or loft deep enough for the unit and ducts plus an access hatch for maintenance. We check that on the survey before recommending one.
Electrical supply
We check the consumer unit on the survey, so the quote covers any electrical work needed. Older boards sometimes need more work to take a new circuit and we will tell you if yours does.
What we’re called out for in AL5
In shops, offices and restaurants, the heat comes from customers, staff, equipment and lighting as well as the sun. Comfortable staff and customers are the usual reason businesses get in touch, along with keeping equipment rooms at a steady temperature.
Most people get in touch when they notice one of these:
- Rooms heated by plug-in heaters
- An office, shop or restaurant that’s uncomfortable for staff and customers
- An ageing air conditioning system near the end of its life
- Working from home in a room that gets too warm
Aftercare tips
Looking after the system is mostly common sense. A few tips:
- Shut doors and windows when it’s on
- Use moderate settings for comfort and economy
- Leave space around the outdoor unit
- Flag any change in how the system sounds or performs
The work area is left tidy: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Pipework outside is covered in trunking or insulated and neatly fixed as agreed on the survey.
Regular filter cleaning is the simplest thing you can do. Clean filters keep the air moving and help the system work as designed, so it uses less electricity for the same comfort.
FAQs for AL5
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book, and we are happy to show ours.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
How much does air conditioning installation cost?
It depends on the rooms, the system and the pipe route, but a single-room split is typically £1,200–£2,200 + VAT. Where you sit in the range depends on pipe length, access, electrics and the model, while commercial systems are priced after a survey.
Do I need a new electrical circuit?
Typically, yes. The fuse board is checked on the survey, and any electrical work goes on the quote, and our NICEIC approval covers the installation and certificate.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Do you have a 24/7 line?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
Will you make a mess?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
