Air conditioning used to be something people associated with offices and hotels abroad. Over the last few years it has become a far more common request in family homes across Reading, Wokingham, Bracknell and the surrounding areas.
We have been qualified to install it for a long time, but it was never something we pushed, for the simple reason that hardly anyone was asking. That has changed noticeably over the last couple of summers, which is why we are talking about it now. The reasons behind that shift are worth understanding, because they suggest it is a change rather than a fashion.
Key Takeaways
- Summers in the south east are getting hotter and heatwaves more frequent
- Modern, well insulated homes are excellent at keeping heat in, which works against you in July
- Extensions, loft conversions and garden rooms overheat more than the rest of the house
- Working from home means people are in the house during the hottest part of the day
- A modern unit heats as well as cools, so it earns its keep in winter too
Summers Have Genuinely Changed
This is not nostalgia or imagination. The Met Office records show a clear warming trend across the UK, with hot spells becoming more frequent and more intense. In July 2022 the UK passed 40°C for the first time in recorded history.
The south east feels this more than most of the country. It is consistently among the warmest regions, and built up areas hold onto heat overnight, so houses get less chance to cool down before the next day starts.
For most of us that used to mean a handful of uncomfortable nights a year. Increasingly it means several weeks where the upstairs of the house is unpleasant to be in.
Modern Homes Trap Heat
Here is the part that surprises people. The better insulated your home is, the harder it can be to cool down.
Everything we have done to homes over the last two decades has been aimed at keeping heat inside: thicker insulation, better glazing, fewer draughts. That is exactly what you want in January. In July, the same qualities work against you. Heat gets in through the windows during the day and then has nowhere to go.
This is now a recognised problem rather than an inconvenience. Building regulations in England were updated with a specific requirement covering overheating in new residential buildings, which tells you how seriously it is being taken.
Newer Properties and Extensions
Newer estates around Wokingham and Bracknell often feel this most, particularly rooms with large south facing windows.
Extensions and loft conversions are another common trigger. A loft conversion sits directly under the roof, and a rear extension with bifold doors and a glazed roof is effectively a greenhouse on a hot afternoon. Both are lovely spaces for nine months of the year and difficult for the other three.
Working From Home Changed the Maths
When most people left the house at eight and came back at six, the hottest part of the day happened while nobody was in.
That is no longer true for a lot of households. If you are working from a home office, a converted loft or a garden room, you are sitting in the warmest part of the building during the warmest part of the day, trying to concentrate. A fan moves hot air around. It does not remove heat from the room.
For a lot of households this is what tips the decision. It stops being about comfort on a handful of evenings and becomes about being able to work through the day.
Modern Units Heat as Well as Cool
This is the point most homeowners do not realise, and it changes the decision entirely.
A modern air conditioning unit is a heat pump. In summer it moves heat out of the room. In winter it runs in reverse and moves heat into the room, usually very efficiently. So rather than sitting idle for three quarters of the year, it is useful whenever you need it.
That makes it a genuinely practical option for spaces your central heating never handled well anyway: a garden room with no radiator, a converted garage, a loft office that is freezing in winter and stifling in summer. Larger properties, of the sort common around Crowthorne, often have exactly this problem in an annexe or outbuilding.
Units Are Quieter and Less Obtrusive Than People Expect
A lot of resistance comes from an outdated mental image: a noisy box rattling away on a wall.
Modern domestic units are considerably quieter than that, and the indoor units are slimmer and plainer than they used to be. Where a wall mounted unit will not suit a room, there are ducted and cassette options that sit largely out of sight.
If the hesitation is about how it will look or sound rather than whether it would help, it is worth seeing a current unit before ruling it out.
What This Means If You Are Considering It
If you have one room that is consistently unbearable in summer, that is usually the place to start. Cooling a single problem room is a far smaller job than most people assume, and it is often the room that also struggles in winter.
The important part is having it sized and positioned properly. An undersized unit runs constantly and never quite gets there. A badly positioned one blows straight at where you sit. Neither is expensive to avoid at the survey stage, and both are annoying to live with afterwards.
FAQs
Does air conditioning use a lot of electricity?
Less than most people expect. Because the unit moves heat rather than generating it, it delivers more heating or cooling energy than the electrical energy it consumes. Running costs depend on the unit, the room and how you use it, which is something we will go through with you before you commit.
Can it be fitted in an older house?
Usually yes. Older properties are often the ones that benefit most, because they are harder to retrofit with other solutions. The practical questions are where the outdoor unit can sit and how the pipework runs between the two, which is what the survey establishes.
Do I need a special installer?
Yes. Air conditioning uses refrigerant gases that are regulated, and installation must be carried out by an F-Gas registered engineer. It is worth checking this before anyone quotes you.
Is it worth fitting one just for a few weeks a year?
If it only cooled, that would be a fair question. Since a modern unit also heats, it earns its place for far more of the year, particularly in a room your central heating has never dealt with properly.
A Practical Response to a Real Change
Air conditioning in Thames Valley homes has moved from an indulgence to a sensible answer to a genuine problem. Summers are hotter, our homes hold heat, and more of us are in them during the day.
If there is a room in your house that you avoid in summer, or one that has never been comfortable in either season, it is worth a conversation. Get in touch and we will tell you honestly if there is a simpler fix first.
