7 Best Air Conditioners: At A Glance

Here’s a quick snapshot of the best air con units we rate this year, so you can compare them at a glance before diving into the full reviews below.

The 7 Best Air Con Units Rated By Our Experts

The best AC units rated by our experts each excel in a different way, so the right choice really depends on your room size, budget and how much you value quiet running versus low upfront cost. We’ve reviewed each of these best air conditioning units below, with a straight answer on who each one genuinely suits.theedinburghboilercompany+1

1. Mitsubishi Electric MSZ-AP – Best for Bedrooms

The Mitsubishi Electric MSZ-AP earns its spot as one of the best wall mounted air conditioning units simply because it’s the quietest split system we’ve come across, dropping as low as 19 decibels on its lowest fan setting, which is genuinely below normal conversation level. It’s also one of the best air conditioning units for bedrooms. 

That matters enormously for bedrooms across Yorkshire’s older stone terraces where thin walls carry sound easily. Compared with the Daikin Sensira, it costs a touch more upfront, but the near silent operation and excellent build quality justify the premium for anyone who values sleep quality over saving a few hundred pounds. 

It also heats efficiently in winter, giving it genuine year round value rather than sitting idle for nine months.

Should You Choose The Mitsubishi Electric MSZ-AP?

Choose the Mitsubishi Electric MSZ-AP if you want the quietest bedroom cooling available and don’t mind paying slightly more for it.

Do not choose the Mitsubishi Electric MSZ-AP if you’re cooling a large open plan living space, as smaller models in this range aren’t designed for bigger rooms.

2. Daikin Sensira – Best for Budget Conscious Households 

The Daikin Sensira sits comfortably among the best air conditioning units because it delivers Daikin’s trusted engineering at a genuinely accessible price point, making it one of the more budget friendly best ac units without cutting corners on core performance. 

It’s slightly noisier than the Mitsubishi at 22dB, but still whisper quiet by older AC standards, and its cooling output scales up to 5.0kW, making it flexible for larger rooms in Midlands new builds with open plan layouts. 

Daikin’s reputation for longevity is well earned too, with many units still running strong after a decade of regular use. If you want a dependable, no fuss unit that won’t break the bank, this is a strong pick.

Should You Choose The Daikin Sensira?

Choose the Daikin Sensira if you want solid, proven performance without paying for premium extras.

Do not choose the Daikin Sensira if whisper quiet bedroom operation is your top priority, as it runs a touch louder than the Mitsubishi.

3. Samsung WindFree Comfort S2 – Best for Draught Free Cooling

The Samsung WindFree Comfort S2 makes our list of the best air conditioners largely because of its clever WindFree mode, which cools rooms through thousands of tiny holes rather than a direct blast of cold air, avoiding that draughty feeling many people dislike. 

This is particularly useful for households with allergy sufferers or anyone who finds traditional air conditioning units too harsh. Compared to the Daikin and Mitsubishi options above, it’s slightly pricier but adds genuine comfort value that goes beyond raw specs. 

It also comes with decent air purification features built in, which suits homes near busy roads in cities like Sheffield or Leeds.

Should You Choose The Samsung WindFree Comfort S2?

Choose the Samsung WindFree Comfort S2 if you dislike direct cold air draughts or have allergy concerns in the household.

Do not choose the Samsung WindFree Comfort S2 if you’re after the absolute lowest running cost, as other units on this list edge it out slightly.

4. Worcester Bosch Climate 3200i – Best for Reliability and Brand Trust

The Worcester Bosch Climate 3200i is one of the best air con units for homeowners who already trust the Worcester Bosch name from their boiler, and that brand trust genuinely carries weight when it comes to aftercare and warranty support. 

It performs comparably to the Daikin Sensira on cooling output but edges ahead slightly on quiet running at 21dB. Given Worcester Bosch’s dominant position in UK heating, having a single trusted brand across your boiler and air conditioning setup simplifies servicing and support, which our engineers hear as a genuine priority from Midlands homeowners especially.

Should You Choose The Worcester Bosch Climate 3200i?

Choose the Worcester Bosch Climate 3200i if you already have a Worcester Bosch boiler and want unified servicing and warranty support.

Do not choose the Worcester Bosch Climate 3200i if budget is your main concern, as it sits at the higher end of pricing on this list.

5. LG Dualcool Premium – Best for Smart Home Integration

The LG Dualcool Premium stands out among the best wall mounted air conditioning units for its smart home integration, letting you control cooling via app, voice assistant or scheduled routines, which appeals to tech savvy households across Manchester and Leeds. 

Cooling capacity scales up to a generous 6.0kW, making it one of the more powerful options here for larger rooms. It runs slightly louder than most rivals on this list, but the trade off is flexibility and genuinely useful smart features that go beyond a basic remote control.

Should You Choose The LG Dualcool Premium?

Choose the LG Dualcool Premium if you want strong smart home control and extra cooling power for bigger spaces.

Do not choose the LG Dualcool Premium if minimal noise is your absolute priority, as quieter alternatives exist on this list.

6. Gree Pular – Best for Landlords

The Gree Pular makes our list of the best air conditioners as the standout choice for landlords managing multiple rental properties, offering genuinely solid performance at one of the more competitive price points around. 

Running costs sit lower than most rivals here at 18-27p per hour, which adds up nicely across several properties over a full season. It’s a touch louder at 26dB, but for rental properties where tenants prioritise value over silence, that trade off usually works in the landlord’s favour.

Should You Choose The Gree Pular?

Choose the Gree Pular if you’re a landlord fitting air conditioning across several rental properties and value cost efficiency.

Do not choose the Gree Pular if whisper quiet operation is essential, as it’s one of the louder units on this list.

7. Midea Xtreme Save Lite – Best for Tight Budgets and Small Rooms

The Midea Xtreme Save Lite rounds out our best air conditioning units list as the go to choice for genuinely tight budgets, without feeling like a compromise unit. It’s the cheapest to run on this entire list at 17-25p per hour, making it well suited to smaller rooms in older properties across the North West where insulation might not be perfect. 

It’s the loudest of our seven picks at 27dB, so it’s not the right fit for a light sleeper’s bedroom, but for spare rooms, home offices or smaller lounges, it delivers excellent value.

Should You Choose The Midea Xtreme Save Lite?

Choose the Midea Xtreme Save Lite if you’re working with a smaller budget and a smaller room, and want the lowest running costs.

Do not choose the Midea Xtreme Save Lite if noise sensitivity is a concern, as it’s the loudest unit reviewed here.

How We Chose The Best Air Conditioners For Bedrooms

We chose the best air conditioners for bedrooms by combining hands-on installation experience with independent efficiency data, real customer feedback and manufacturer warranty terms, rather than relying on marketing claims alone. 

As a team of Gas Safe and F-Gas certified engineers who’ve fitted air conditioning units across the North West, Yorkshire and the Midlands for years, we’ve seen firsthand which best AC units actually hold up in real British homes.

• Noise levels tested in real rooms, not just manufacturer lab figures, because a unit that’s “quiet” on paper can still disturb sleep
• SCOP heating efficiency ratings compared across brands to identify genuine year round value, not just summer cooling performance
• Running costs calculated at current Ofgem electricity rates so figures reflect what UK households actually pay
• Warranty length and manufacturer support reviewed to gauge long term reliability and aftercare
• Suitability for typical UK housing stock, including older terraces and stone built properties common across Yorkshire and the North West
• Customer feedback and callout history gathered from our own installation records over multiple years
• Brand reputation and parts availability, ensuring servicing and repairs remain straightforward for years to come

How To Choose The Best Air Conditioners For Your Home In The North West?

Choosing the best air conditioners for your home in the North West comes down to matching unit size, noise tolerance and budget to your specific property, rather than picking whichever best ac unit ranks highest on a generic list. The region’s mix of Victorian terraces, modern apartments and detached family homes each present different considerations worth thinking through properly.

Matching unit size to room dimensions

Getting the kW output right matters more than most buyers expect. A 2.5kW unit suits a standard bedroom, while larger open plan living areas common in newer Manchester and Liverpool developments typically need 3.5kW to 5kW to cool effectively without the unit constantly running at maximum output.

Considering your property’s insulation

Older stone and brick terraces across Yorkshire and parts of Greater Manchester often lose cool air faster than modern insulated builds. Homes with poorer insulation may need a slightly higher capacity unit than the room size alone would suggest, so factoring this in avoids disappointment after installation.

Prioritising noise levels for bedrooms

Anyone fitting air conditioning in a bedroom should weigh noise output heavily, since even a five decibel difference between units becomes noticeable over a full night’s sleep. This is where units like the Mitsubishi Electric MSZ-AP genuinely earn their premium price tag.

Checking heating capability for year round value

Many of the best air conditioning units double as efficient heat pumps in winter, delivering warmth at a lower running cost than gas in many cases. Checking the SCOP rating before buying ensures you’re not paying for a unit that sits unused for three quarters of the year.

Factoring in installation and F-Gas compliance

UK regulations require F-Gas certified engineers to handle refrigerant based installations, so always confirm your installer holds the correct certification. This protects your warranty and ensures the unit is fitted safely and legally.

Weighing upfront cost against long term running costs

A cheaper unit upfront can sometimes cost more over five years if its running costs and heating efficiency lag behind pricier alternatives. It’s worth calculating total cost of ownership rather than focusing purely on the installation invoice.

FAQs

Do I need planning permission to install air conditioning in the UK?

Most domestic wall mounted air conditioning units don’t require planning permission under permitted development rights, though listed buildings and flats can have additional restrictions worth checking with your local council first.

How long does an air conditioning unit typically last?

A well maintained split system air conditioner typically lasts between 10 and 15 years, with lifespan heavily influenced by regular servicing and how consistently it’s used throughout the year.

Can air conditioning units also heat my home in winter?

Yes, most modern wall mounted units function as reversible heat pumps, delivering efficient heating during colder months at a running cost that’s often competitive with gas central heating.

What’s the difference between a single split and multi split air conditioning system?

A single split system cools one room from one outdoor unit, while a multi split system connects several indoor units to a single outdoor condenser, making it more cost effective for cooling multiple rooms in a property.

Do air conditioning units need annual servicing?

Yes, annual servicing helps maintain efficiency, catches refrigerant leaks early and typically keeps manufacturer warranties valid, so it’s a worthwhile yearly investment rather than an optional extra.
