Air conditioning installation in Northaw
Thinking about air conditioning but not sure where to start? Just phone us on 07833 053749 with photos of the rooms and the outside of the property, and we will reply the same working day about a survey or a fixed-price quote. Every installation in Northaw begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
Around Northaw, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

How we price air conditioning
We quote each job individually. This is what makes a difference:
- The condition of any existing system
- The distance and route between the indoor and outdoor units
- How easy the units are to reach
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Asking for a quote
Good pictures often save a visit. The most useful are:
- Any error code or flashing light on the display
- Your installation or service records
- The fuse board and where it is in the property
To help us quote: the address and the type of property, a few pictures, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Once you have those, call us on 07833 053749 or send an email.
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. The visit takes about a day for a single-room system, longer for multi-room and ducted systems. Visits to Northaw are agreed with you in advance and planned so the job can be finished in one trip where possible.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
How to prepare
- Tell us about any building rules, permits or sign-in
- Name a contact who can meet us at the agreed time
- Clear a path to the units and the space around them

Air conditioning in Northaw: the local picture
VOA council tax data date about 44% of homes in and around Northaw to the post-war years, 1945 to 1972, and the 2021 Census found about 84% of households in detached or semi-detached houses. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
Homes near Parish Church of St Thomas A Becket are a good example of where we look up the heritage status of the building before fixing anything to it. Wyllyotts Manor (roughly 2.1 miles west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Northaw: your questions answered
Can you do air conditioning in Northaw?
Yes, Northaw is within the area we cover. Just ring us on 07833 053749 or send an email with a few details.
Is planning permission needed for air conditioning in Northaw?
It depends on the property. The Northaw Village Conservation Area is close to the centre of Northaw. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t 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 local planning authority (for Northaw, typically Welwyn Hatfield council).
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Every visit is recorded and F-Gas records kept where they apply.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
How quickly will you reply?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Do I need to service the system to keep the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
For landlords and property managers
We regularly work with managing agents. Tell us the property, the work and the access arrangements and we will come back with a fixed-price quote.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
When something else is needed
We’d rather tell you now than sell you work that will not help, so these are the things it won’t cover:
- Building damp that has a structural cause
- Gas boiler or central heating faults (we do not work on gas boilers)
- A room that can’t take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
If you are not sure, just ring 07833 053749 or write to us at info@aircondoctor.co.uk and we will give you a straight answer before booking.

From one of our customers
“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.”
