How air conditioning works in WD17
Most air conditioning needs its own electrical supply from the consumer unit. Under Part P, a new circuit is notifiable unless a registered competent person does it, and our NICEIC approval means we install and certify it ourselves. The work covers multi-split systems, VRF systems and ceiling cassettes, and people most often call us about an old system that needs replacing and rooms heated by plug-in heaters.
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes anything from a day for one room to several days for a multi-room or ducted system.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
What you’ll pay
The price reflects the work, not guesswork. That’s why every job is looked at first, and the price is agreed before work begins.

Around Cassiobury
We fit and service air conditioning in homes and premises around Watford Grammar School for Girls, St John's Church and The Estcourt Tavern and the streets around them. You’ll also find Watford St John's Church of England Primary School (under half a mile south-east), Croxley Danes School (1.4 miles west) and Cassiobury Park (0.7 miles west). Cassiobury has its own railway station: Watford Junction station. Nearby you’ll also find Charter Place (within half a mile south-east) and Watford General Hospital (0.8 miles south). For a walk, there’s Harrow Weald Common.
Air conditioning across WD17
From Watford, Cassiobury and Oxhey outwards, WD17 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.
Our area stretches from Greater London through Surrey, Kent and Sussex to Hampshire, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and WD17 sits within it. You reach the same people wherever you are in it.
Cassiobury: Living close to St John's Church? Some older properties in parts like that are protected, and the survey finds out whether yours is. High Elms Manor (roughly 2.9 miles north) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
Aftercare tips
Systems last better with the right care. Here’s what we suggest:
- Close windows and doors while the system is cooling
- Use moderate settings for comfort and economy
- Keep the handover documents somewhere safe
- Keep the outdoor unit clear of leaves, plants and clutter
Questions after the installation go to the same number. Tell us what the system is doing, and any code on the display, and we’ll talk it through with you.
Regular filter cleaning is the simplest thing you can do. Clean filters keep the air moving and help the system work as designed, which costs you more to run.
System by system
Ceiling cassettes
A cassette needs a void above the ceiling for the unit, pipework and drain, and many use a built-in condensate pump to lift the water away. We check the ceiling void on the survey.
Electrical supply
Most systems need their own circuit from the consumer unit. As NICEIC approved contractors, we install it and issue the certificate and that covers the Part P side.
What we’re called out for in WD17
Some people come to us for heating rather than cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, which means more heat out than electricity in. Most modern split systems work this way.
The things we are asked about most include:
- Working from home in a room that gets too warm
- A loft conversion that is too warm to use
- Rooms that get too hot to sleep or work in
- Expensive direct electric heating
Fixed-price quotes for air conditioning in WD17
Our prices page gives typical ranges, and your quote is built on your job. The quote depends on:
- Access, including height, roofs and ladders
- What we find on the survey or diagnosis
- The pipe route between the units
- Whether it’s a simple split or a larger system
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.
Before you get in touch
There’s no need for technical detail. Just send:
- Any error code or flashing light on the display
- Where the property is and what kind of building it is
- The rating plate or label on any existing unit
- A few pictures of the room and the wall the unit is on, or will go on
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
WD17 questions
How long does it take to fit air conditioning?
It takes anything from a day for one room to several days for a multi-room or ducted system. The survey tells us how long your installation will need, so you can plan around it.
Do you look at the job first?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
How quickly will you reply?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
What size air conditioning unit do I need?
Sizing is done on the survey, room by room. An undersized unit never catches up, and an oversized one cycles and wastes energy, so we explain why we have chosen a particular output.
