Different systems, different jobs
Multi-split systems
A multi-split runs several indoor units from one outdoor unit. It saves wall space outside and suits homes where several rooms need cooling, with each room controlled separately.
Pipework and condensate drains
We pressure test and evacuate the pipework before the system is charged, so the system starts life clean, dry and leak-tight. It’s recorded in the commissioning details.
About our air conditioning in Newgate Street
Across Newgate Street, every installation follows the same steps: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. You know the price before we start and the paperwork is in your hands when we finish. Need an air conditioning installer for Newgate Street? AirCon Doctor works across London and the South East from East Grinstead, as an F-Gas certified company with NICEIC approval.
A single room takes a day in most homes, while multi-split systems for several rooms can take longer, and we leave the room clean and the controls explained.
Around Newgate Street, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.

The process
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. If a lane or gateway near Newgate Street is tight for a van, let us know and we will plan for it.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Clear access to the fuse board
- Clear the space around the indoor unit, or where it will go

Looking after your system
After the visit, a few habits help:
- Keep the handover documents somewhere safe
- Keep the indoor unit’s filters clean
- Tell us if the unit starts to leak, rattle or show a code
We clear up before we go: sheets removed, packaging cleared up and pipe holes sealed. Outside, the pipework is neatly fixed and protected as agreed on the survey.
Report drips, noises or error codes early. Water from the indoor unit, a new rattle or a code on the display typically means something needs attention and catching it early keeps the repair small.
Why it’s worth doing now in Newgate Street
A system that is the wrong size never works well. Too small, and it runs flat out without catching up; too big, and it switches on and off and wastes energy. Sizing each room properly on the survey avoids both. Dealing with it now is normally simpler than a breakdown later.
Our prices page shows typical ranges, but your price depends on the job in front of us. For a fixed-price quote, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk, and we will explain what it covers.

Air conditioning around Newgate Street
About 44% of homes across Newgate Street and its surrounding area date from 1945 to 1972, according to Valuation Office Agency council tax records, and Census 2021 figures 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. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
With historic houses such as Wyllyotts Manor about 4 miles south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules. Around Church of St Mary Ponsbourne, a quick check of the listing and conservation maps is part of planning any install.

Newgate Street questions
Will air conditioning in Newgate Street need planning permission?
It depends on the property. The half-mile around the middle of Newgate Street holds about 7 listed buildings and structures. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Newgate Street, usually Welwyn Hatfield council) when it matters.
Do you cover Newgate Street for air conditioning?
We do: Newgate Street falls inside our working area. Get in touch with the details and we reply the same working day.
How do I know what size unit to get?
We size each room on the survey, from its size, glazing, orientation and use. An undersized unit never catches up, and an oversized one cycles and wastes energy, so we explain why we have chosen a particular output.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
