How air conditioning works in EN5
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see and we talk you through it on the survey. Common call-outs are for a loft room or top floor that bakes in summer and fans and portables that don’t keep up, on air-to-air heat pumps, multi-split systems and ducted systems.
We keep the work area tidy as we go, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer.
- You send photos, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How we quote
The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before any work starts, so you know where you stand.
What you get with us
- F-Gas company certification
- A 24/7 emergency line
- We diagnose before we treat
- NICEIC approved for electrical work
Getting a quote
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To start, call 07833 053749 or email us.
Landmarks near Barnet

The nearest railway station is New Barnet station, roughly 0.6 miles east.

Air conditioning around EN5
From Barnet, New Barnet and High Barnet outwards, EN5 has every kind of home. Each install starts with a survey of the rooms, the walls and where the outdoor unit can go, then a fixed-price quote.
Across London and the South East, we reply to enquiries the same working day, with a 24/7 emergency line for breakdowns.
Barnet: Wyllyotts Manor (roughly 3.5 miles north) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. Older streets near St John's United Reformed Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.
What owners can safely do
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Keeping the system healthy
To keep the system working properly:
- Book an annual service
- Let filters dry fully before you put them back
- Keep the F-Gas records, commissioning details and warranty information together
- Keep the room closed while it runs
Questions after the installation go to the same number. Tell us what the system is doing, and any code on the display and we will help you sort it out.
Clean the filters regularly, not just at the service. Clean filters keep the air moving and help the system work as designed, so it uses less electricity for the same comfort.
Why act early?
Refrigerant rules have changed what new systems use. Since 2025, new single split systems with less than 3 kg of refrigerant cannot use F gases with a GWP above 750, which is why R32, with a GWP of 675, is now common. Older R410A systems have a GWP of 2088.
What your quote should include
- What paperwork you’ll receive afterwards
- What the manufacturer’s warranty covers and for how long
- Whether the company is F-Gas certified, and whether you can check it
- The make and model of any parts or equipment being quoted
Fixed-price quotes for air conditioning in EN5
The diagnosis comes before the price. We look at:
- The number of rooms, units or zones
- Which make and model is being fitted or worked on
- Whether the existing supply is suitable
- What we find on the survey or diagnosis
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered and we will price it together.
Helping us quote
Photos and a few facts are often enough to price a simple job. Useful things to send:
- The remote or wall controller showing any error
- The postcode and whether it’s a home, flat or business
- The make and model of the system, from the label
- The fuse board and where it is in the property
For a fixed-price quote, call 07833 053749 or fill in the contact form with the address and a few details about the rooms or units involved. A few photos make it quicker. You’ll hear back from us the same working day.
Questions from EN5
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
How long does it take to fit air conditioning?
It takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. The survey tells us how long your installation will need so there are no surprises.
Do you work on systems someone else installed?
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.
Which type of system should I choose?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
What accreditations do you have?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are members of Checkatrade too.
