The process
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Pictures of the space and where the outdoor unit could go let us plan the work in Gustard Wood.
- We survey the property, or work from your photos for a simple job.
- The system is sized, positions are agreed and the price is fixed.
- We protect the area, then fit both halves of the system.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Let us know if the units are on a roof, a high wall or in a locked area
- Find the manual or the paperwork for the system, if you have it

Photos are enough for some jobs; others need a visit first. 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.

In a village like Gustard Wood, many homes are older, and some are listed. We check that first, because permitted development does not apply within the grounds of a listed building.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

What air conditioning won’t do
We’d rather tell you now than sell you work that will not help, so here are the limits:
- An installation that needs consent nobody has given yet
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- Draughts and missing insulation
Not sure which it is? You can phone us on 07833 053749 or email us and we will tell you honestly before booking.

FAQs for Gustard Wood
Can I fit air conditioning in Gustard Wood without planning permission?
That depends on the building and where the outdoor unit goes. Central Gustard Wood sits inside the Gustard Wood Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Gustard Wood, typically St Albans City council).
Do you cover smaller places like Gustard Wood?
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.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
How much does air conditioning installation cost?
A single-room split system is typically £1,200–£2,200 + VAT. A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, with supply, fitting, commissioning and F-Gas documentation included. You get a fixed price before any work starts.
Keeping the system healthy
How well a system lasts depends on use and care. Here’s what we suggest:
- Have the system serviced once a year
- Keep the indoor unit’s filters clean
- Refit filters properly after cleaning
The work area is left tidy: sheets removed, packaging cleared up and pipe holes sealed. Pipework outside is covered in trunking or insulated and neatly fixed, so the job looks as tidy as it works.
Give the outdoor unit room to breathe. Leaves, plants, bins and stored items around it restrict the airflow, and the system has to work harder as a result.
Fixed-price quotes for air conditioning in Gustard Wood
Our prices page gives typical ranges, and your quote is built on your job. The quote depends on:
- Whether we need access equipment for high-level work
- The number of rooms, units or zones
- What we find on the survey or diagnosis
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- A close-up of the unit’s label showing the model number
- Wide pictures of the room or the existing unit
- A short video of any fault, such as a noise or a flashing light
Quotes do not take long. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
