Where air conditioning is worth it in Stevenage
South facing rooms in the newer town centre regeneration flats and the more recent developments towards Great Ashby and Whitehorse Lane are the properties we get called to most, large glazing that a New Town semi from the 1950s or 1960s simply was not built with. Those older properties can still benefit, particularly a loft conversion or a garden room with limited natural ventilation, but the case is usually less clear cut than in a modern flat with floor to ceiling glass on one elevation.
Commercial units in the town centre, especially retail and office space caught up in Stevenage’s ongoing regeneration programme, are the other main driver, server rooms, busy shop floors and offices with a lot of equipment or footfall all generate heat that opening a window will not solve.

What we install
Split systems for a single room, multi split systems where more than one room needs cooling from a single outdoor unit, and commercial systems sized properly for the space rather than sold on the smallest box that technically fits the specification sheet. We survey the property first, check where the outdoor unit can realistically go, and size the system to the room rather than guess.
All our engineers hold F-Gas certification, which is a legal requirement for anyone installing or handling refrigerant in the UK, not an optional extra. Air conditioning currently benefits from 0% VAT until 31 March 2027 under HMRC Notice 708/6, on qualifying residential installations, and we will confirm whether your job qualifies as part of the quote.
Regeneration flats and shared buildings
If you are in one of the newer town centre developments, outdoor unit placement is often the deciding factor, some buildings restrict where a condenser can be fixed on the exterior, and a managing agent may need to approve the installation before we start. We will ask about your building when you call, because the survey and the paperwork for a managed development is not the same as for a detached house with a garden to put the outdoor unit in.
For houses in Chells, Pin Green or the older New Town streets, outdoor unit placement is usually far more straightforward, though we still check noise levels against neighbouring windows before confirming the final position.
Booster showers, extensions and other constraints
Where a property already has a lot of electrical demand, an EV charger and a booster shower pump on top of normal household use, for example, we check the consumer unit and available capacity before confirming a system, since air conditioning adds meaningfully to the electrical load. This is a straightforward check on survey day and rarely rules a job out, but it is worth doing properly rather than discovering it after installation.
Guarantee
We are Gas Safe registered under 956889, Company No. 13248357, and every air conditioning installation carries a 12 month labour guarantee alongside the manufacturer’s own warranty on the equipment. Engineers are F-Gas certified as standard, which is not optional under UK law for anyone handling refrigerant.
What installation day looks like
We fit the indoor wall unit, run the pipework and cabling through to the outdoor condenser, and commission the system before we leave, checking refrigerant charge and running the unit through its full range to confirm it cools and, where fitted, heats correctly. A single split system is normally a one day job. A multi split with several indoor units, or a commercial system across multiple rooms, can run to two or three days depending on the pipe runs involved.
We keep disruption to a minimum, most of the work is on the outside wall and a short section of pipework run internally, usually boxed in neatly rather than left exposed unless you specifically prefer to see the pipe run.
Fitted right first time, F-Gas certified
Survey, supply, installation and commissioning by our own engineers, with the trunking run properly.
Running costs and choosing the right size
An undersized unit runs constantly and struggles to hold temperature on a hot day, while an oversized one cycles on and off more than it needs to, neither is efficient. We size the system to the room’s actual glazing, aspect and use, not just floor area, which is why a survey matters more than a quick online calculator. Most modern inverter driven systems are considerably more efficient to run than older on-off units, and we will talk you through the running cost difference as part of the quote.
Annual servicing keeps a system running efficiently and is worth budgeting for alongside the installation itself, particularly on a commercial system that runs for long hours through the summer.
Commercial installations in Stevenage town centre
Retail units and offices caught up in the town centre regeneration programme often have specific landlord requirements around external plant, noise limits, and sometimes a shared plant deck rather than individual condensers on the building’s exterior. We survey commercial jobs with those constraints in mind from the outset and will flag anything that needs landlord sign off before we quote, rather than after a system has already been ordered.
Server rooms and comms cabinets are a specific case, needing continuous cooling rather than a system that can be switched off overnight, and we size and specify those differently from a standard office space.
Booking a survey
We come and look at the room, check where the outdoor unit can go and what pipe run that means indoors, and give you a written quote afterwards rather than a number over the phone. If you are in a managed building, mention that when you call so we know to factor in the approval process from the start.
Call 01462 506 374 to book, no call out fee in hours, and no pressure to go ahead once you have seen the price.
Heating and cooling from the same system
Most of the split systems we fit can run in reverse as an efficient heat source for the room they serve, not just cooling, which is worth knowing if you are weighing air conditioning against a separate electric heater for a garden room or loft conversion. It will not replace your main heating system, but for a single room used at odd hours, an office above a garage or a home gym for example, it is often a cheaper way to keep that one space comfortable year round than running a boiler zone just for it.
We will tell you plainly if that dual use makes sense for your particular room, since it does not suit every space, a room with poor insulation will still lose heat quickly regardless of what is supplying it.
Servicing an existing system
If you already have air conditioning fitted, whether by us or another installer, we also carry out annual servicing, filter cleaning, refrigerant checks and a general performance check before the season it is needed most. A system that has not been serviced in a couple of years often just needs a clean and a refrigerant top up rather than a repair, and we will tell you which one it actually is before quoting anything.

Frequently asked questions
Does air conditioning make sense in an older Stevenage house?
It can, particularly for a loft conversion or a room with limited ventilation, though the case is usually stronger in a modern flat with large south facing glazing. We will give you an honest assessment on survey rather than sell a system that will not make a meaningful difference.
Is VAT reduced on air conditioning installation?
Air conditioning currently benefits from 0% VAT until 31 March 2027 under HMRC Notice 708/6 on qualifying residential installations. We will confirm whether your specific job qualifies as part of the quote.
I am in a town centre flat. Can I get air conditioning fitted?
Often, yes, but outdoor unit placement usually needs approval from the managing agent first, since some buildings restrict what can be fixed to the exterior. Tell us your building when you call so we can factor that into the survey.
Are your engineers qualified to handle refrigerant?
Yes, all our engineers hold F-Gas certification, which is a legal requirement in the UK for anyone installing or handling refrigerant, not an optional extra we mention for marketing purposes.
Will air conditioning overload my electrics?
Usually not, but if you already have significant electrical demand, an EV charger alongside a booster shower pump for example, we check the consumer unit and available capacity on survey day before confirming the system.
What warranty covers an air conditioning installation?
Every installation carries a 12 month labour guarantee from us, alongside the manufacturer’s own warranty on the equipment itself.
