Why Dunstable homes overheat in the first place
Dunstable sits at the foot of the Dunstable Downs, the highest point in the East of England, but there is no river running through the town. Unlike Hertford or Ware there is no river corridor and no valley air moving through the middle of it, and most of the housing is two storey estate stock built between the 1930s and the 1970s. When a still, hot week arrives, that housing holds its heat.
The rooms that suffer are predictable. Converted lofts on the Beecroft, Downside and Poynters estates, insulated to keep winter heat in and with the roof tiles a metre above your head. South and west facing bedrooms that take sun all afternoon. Glazed rear extensions that gain heat faster than an open door can shed it. And the small back bedroom that has quietly become a full time office, with a computer, two screens and a person in it from eight until six.
There is no heating system fix for any of that. A wall mounted split system is the fix, and because it is an air to air heat pump it earns its keep in winter too.
These units heat as well as cool, and that is half the point
Every system we install is an air to air heat pump. In summer it moves heat out of the room. Run in reverse in winter it moves heat in, delivering several units of heat for each unit of electricity it uses, which makes it one of the cheapest ways to run heat into a single room.
Around Dunstable that matters most in the rooms the radiators never really reached. A loft conversion at the far end of the heating circuit. A garage conversion on a post war estate where nobody ever extended the wet system properly. A garden office with no heating at all. One machine solves the July problem and the February problem in the same box, without running new 15mm pipework through the house.
The kit we fit around Dunstable
Wall mounted single splits. One indoor unit, one outdoor unit, and the standard answer for a loft room, a bedroom or a home office. The least disruptive install of the lot.
Multi-split systems. Two to five indoor units running from a single outdoor condenser. The right answer where you want the main bedroom, the loft and the office all covered but only want one box outside.
Ducted and concealed systems. The indoor unit hidden in a ceiling void or cupboard with air delivered through grilles. More work and more money, and worth it in a high specification refurbishment.
Floor mounted and low wall units. Handy under a window or in a loft room where the sloping ceiling rules out a high wall position.
We install Daikin, Mitsubishi Electric, Samsung, LG and Fujitsu, and we choose from those ranges after the survey, based on the heat gain, the pipe route and how quiet the room needs the indoor unit to be. We size room by room using a heat gain calculation, not floor area alone. An oversized unit short cycles, dehumidifies poorly and makes more noise than it should, so the quote with the biggest kilowatt number on it is rarely the right one.
Where the outdoor unit goes, estate by estate
On most of Dunstable’s housing this is straightforward. The Lake District Estate, Oldhill Down and Stipers Hill in the south west, the Downside and Englands Close side in the south east, Northfields and the 1960s redevelopment in the north east, and Jeans Way, the Hadrian and Woodside estates to the east are all post war stock with gardens, side returns and rear walls that give us sensible low level positions on anti-vibration feet, out of sight and out of earshot.
The town centre is a different conversation. Dunstable’s conservation area was designated in 1976 and takes in High Street North, High Street South, West Street, Church Street, Albion Street, Edward Street, Icknield Street, The Square and Middle Row, with 53 listed buildings inside it, from 15th century properties at Nos. 16 to 20 West Street through Victorian terraces. An outdoor condenser is exactly the kind of external alteration that needs heritage thought in those streets, and a listed building needs consent for work like this. We are not going to recite planning rules at you here, because the answer depends on your exact address. What we will do is check the position with Central Bedfordshire Council before the system is designed, put the unit at the rear at low level where it cannot be seen from the street, and tell you plainly if consent is needed before you have spent anything.
In flats and leasehold conversions around the town centre, the freeholder or managing agent usually has to approve anything fixed to the external fabric, and we provide the technical drawings and noise data for that application.
What an installation in Dunstable actually involves
A single split in a straightforward house is a day’s work for two engineers. A multi-split across three or four rooms runs to two or three days.
We agree the indoor and outdoor positions before anything comes off the van, then core drill the wall for the pipe route. Refrigerant pipes, the control cable and the condensate drain all travel together, so the route is the part of the job worth planning hardest. The outdoor unit goes on brackets or a ground frame with anti-vibration pads, then the system is pressure tested with nitrogen, evacuated under deep vacuum to remove moisture, charged, commissioned and demonstrated. Electrical work is carried out by qualified electricians and certificated as part of the job.
Condensate is where cheap installs let people down. An indoor unit in cooling mode makes water, and that water needs a continuous fall to a proper drain, or a small condensate pump where gravity cannot do it. A pipe poked through the wall to drip down the render is not an installation, it is a stain waiting to happen. We terminate it properly and lag what needs lagging.
One local point worth making: Dunstable’s water from Affinity Water’s own Dunstable supply zone is published at a mean of 310 mg/l calcium carbonate, which is above the standard 300 mg/l very hard threshold. That scale problem belongs to the wet side of your plumbing, not to the refrigerant circuit, so air conditioning is one of the few systems in a Dunstable home the water cannot fur up. The condensate the unit produces needs a clear route regardless, and we check it at every service.
What it costs
We do not publish a price, because a single split in a modern bedroom on the Woodside Estate and a multi-split threaded through a listed building off High Street South are not the same job.
What moves the number is the count of indoor units, the length and difficulty of the pipe run, wall bracket versus ground frame outside, whether a condensate pump is needed, and the making good. Ducted systems cost more because most of the work is hidden above the ceiling.

Servicing, F-Gas and warranties
An annual service keeps the system efficient and quiet. Filters cleaned, coils checked, condensate route confirmed clear, refrigerant charge verified. Many manufacturers make regular servicing a condition of the equipment warranty, depending on the brand and its terms, so it pays to read what yours requires.
Refrigerant is a controlled substance. Our installation, servicing and decommissioning work is done under F-Gas requirements, including proper recovery when an old system comes out, rather than venting gas to atmosphere.

Heating work in Dunstable at the same time
Plenty of cooling enquiries here start life as heating complaints. The loft room that roasts in July is usually the same room that never warms up in February. If the boiler is tired or the upstairs radiators have never been right, it is worth pricing both jobs together and paying once for the access and the making good. We also cover boiler installation, general plumbing, power flushing, leak detection and drainage across LU5 and LU6: boiler installation in Dunstable, general plumbing in Dunstable, power flushing in Dunstable, leak detection in Dunstable, drainage services in Dunstable.

Frequently asked questions
Do I need planning permission for air conditioning in Dunstable? For most houses on the post war estates the outdoor unit siting is straightforward. Inside the town centre conservation area, which covers High Street North and South, West Street, Church Street, Middle Row and The Square, external plant needs heritage thought, and listed buildings need consent. We check your address with Central Bedfordshire Council before designing anything.
Does my installation qualify for 0% VAT? Yes. Residential supply and installation of qualifying energy saving materials is zero rated under HMRC VAT Notice 708/6, currently to 31 March 2027, and the quote shows it.
Will it heat the room in winter? Yes. These are air to air heat pumps and they run in reverse to heat very efficiently. Many customers run them as the main heat source in a loft room or garden office.
How long does the installation take? A single split is usually one day with two engineers. A multi-split across several rooms is two to three days depending on the pipe routes.
How many rooms can one outdoor unit serve? A multi-split typically runs two to five indoor units from one condenser, which keeps the outside of the house tidy.
Will Dunstable’s hard water damage the system? No. Affinity Water publishes the Dunstable zone at a mean of 310 mg/l calcium carbonate, which is very hard, but air conditioning is a sealed refrigerant circuit with no mains water in it. The condensate drain still needs checking at each annual service, and we do.
