AIR CONDITIONING EXPLAINED
One system. Year-round comfort. Discover how air conditioning works, what affects running costs and why more homes are preparing for warmer summers.

Put simply, air conditioning takes unwanted heat out of your room. The indoor unit circulates cooler air around the space, while the outdoor unit releases the heat outside. The result is a room that feels more comfortable on a warm day.
You choose the temperature you want using the remote or compatible app. The system then works towards that setting, helping you maintain a comfortable room without having to keep adjusting it.
Unlike a fan, which moves the existing air around, air conditioning actually removes heat from the room. And with a system that offers heating too, the process can work the other way: bringing heat indoors when you need warmth.
There is no need to understand the machinery. Tell us which rooms feel too hot or too cold, and we can help you choose a system that suits the space and how you use it.
Air conditioning can be useful beyond summer. A reversible air-to-air heat pump uses the same indoor and outdoor equipment for both heating and cooling. Instead of removing heat from your home, heating mode reverses the process so the system collects heat outside and releases it into the room.
This gives you a way to warm a home office, bedroom or living space as well as keep it comfortable during warmer weather. It can be considered alongside an existing heating system; whether it is suitable as the main source of heating needs an assessment of the rooms and their heat losses.
Choose a comfortable temperature, the appropriate heating or cooling mode and a fan setting that suits the room. Controls vary by model, and a multi-room system may require connected units to operate in the same heating or cooling mode.
Many newer systems offer Wi-Fi control, bringing compatible units together in one app. Adjust temperatures, set schedules and manage individual rooms—or groups of units—even when you are away. Some models have Wi-Fi built in; others need an optional adapter. Availability, app compatibility and features depend on the equipment, so we can help you choose a setup that works together.
Efficient equipment matters—but there is no honest one-price-fits-all running cost. Your bill depends on the electricity consumed, your tariff, the weather, the temperature you choose and how long the system operates. Room insulation, glazing and the system design also make a difference.
Do not confuse a unit’s heating or cooling capacity with the electrical power it uses. They are different figures. Ask for the proposed model’s seasonal efficiency information and an estimate based on your space and intended use.
A simple illustration, not a prediction: if a system consumes 0.5 kWh during one hour, and electricity costs 30p per kWh, that hour costs 15p. Actual consumption changes with demand; this is not a quoted cost for an Alpha installation.
Potential heating savings also depend on what you are replacing. Energy Saving Trust notes that UK air-to-air performance data is limited, so a guaranteed percentage saving would be misleading. Cooling adds electricity use compared with not using mechanical cooling.
A good starting point is a correctly specified system, sensible settings, shading and regular care—not an exaggerated savings promise.
Hot weather is becoming a more regular consideration for UK homes. The Met Office reports that warming is increasing the frequency, duration and intensity of extreme heat. Its research points towards hotter summers on average, although individual summers will still vary.
That does not mean every day will be hot, or that every property needs air conditioning. It does make it worth thinking about which rooms become uncomfortable and why. A sunny bedroom, heavily glazed living area or busy home office may have very different needs from the rest of the building.
Start with practical ways to limit heat coming in: shading, blinds and reducing unnecessary indoor heat sources. Suitable ventilation can help when the outdoor air is cooler. If these measures do not provide enough comfort, targeted cooling is an option to discuss.
Planning ahead gives you time to compare equipment, locations and running-cost expectations. The aim is a proportionate solution for the rooms you actually use—not installing more capacity than the space requires.
Quiet comfort starts with the right equipment and placement. Sound levels vary between models, fan speeds and operating conditions. A low-noise or night setting can be useful in a bedroom, but the lowest advertised sound figure should not be treated as the sound you will hear at every setting.
There are two parts to consider: the indoor fan and airflow, and the outdoor unit. What you notice also depends on where you sit or sleep, background sound and how the equipment is mounted. “Quiet” should mean appropriate for your space—not a promise of silence.
Useful questions to ask before choosing a system include:
Careful siting, suitable mounting and the required clearances help manage sound and vibration. Tell us if sleep, video calls or another noise-sensitive activity is a priority so that it can be considered from the outset.
It starts with understanding the space. Before installation, the layout, room use, equipment positions and access need to be assessed. It is also the time to agree the visible pipework route, condensate drainage and electrical requirements, rather than leave those details as a surprise.
A typical split system has an indoor unit and an outdoor unit linked by refrigerant pipework and cabling. Fitting them involves fixing equipment in place and making an opening for the connecting services. The work is more involved than plugging in a portable appliance.
There will be some drilling noise and a working area that needs to be accessible. The amount of disruption and time required depend on the number of units, the building and the route between them. Ask for the expected programme and what is included in the quotation.
The final stage is testing and commissioning, followed by an explanation of the controls and routine care. Keep the equipment details and warranty information together, and check any servicing conditions. You should finish with a clear understanding of how to use and look after the system.
Room size is a useful starting point. Multiply the length by the width to find the floor area in square metres. For example, a room measuring 5 metres by 4 metres has a floor area of 20 m².
| Room area (m²) | Approx. kW | Approx. BTU/hour |
|---|---|---|
| 20 | 2.0 | 6,800 |
| 25 | 2.5 | 8,500 |
| 35 | 3.5 | 12,000 |
| 50 | 5.0 | 17,100 |
These examples use a rough starting point of 100 watts per m², assuming typical insulation and ceilings around 2.4 metres. BTU/hour figures are rounded equivalents, not specific model recommendations.
kW here means cooling capacity, not electricity consumption. BTU/hour is another way of expressing that capacity.
Every room is different. Windows, sunlight, insulation and room use affect the capacity required. This table is an initial guide—not a system recommendation. Alpha HVAC will confirm the right size for your heating and cooling needs during your survey.
