LG DUAlCOOL Special EZ Review: Worth The Investment For Your Home?

The UK’s 0% VAT window is closing. Until 31 March 2027, qualifying energy-saving installations can still benefit from 0% VAT, but from 1 April 2027, qualifying installations are expected to return to the reduced VAT rate of 5%.

With the deadline approaching, is now a good time to invest in a heat pump system like the LG DualCool Special EZ?

Before we get into the product details, let’s see how much you could save with the current 0% VAT relief.

What Could 0% VAT Actually Save You?

According to Checkatrade, air conditioning installation in the UK can cost between £1,750 and £3,000, depending on the property, system type, and installation requirements.

Checkatrade also states that an air-to-air heat pump is normally around £3,000 for supply and installation.

However, if qualifying installations return to 5% VAT after 31 March 2027, that 5% difference could look like this:

While this won’t change the total cost by much, it’s still a helpful saving.

This amount could help pay for a service plan, upgraded controls, or just make the installation cost feel a bit less painful.

More importantly, it’s another reason not to wait until after the VAT relief ends to upgrade to an energy-efficient heating and cooling system.

Now that we’ve covered why you might want a heat pump, let’s talk about what the LG DualCool Special EZ actually is.

What Is The LG DualCool Special EZ?

The LG DUALCOOL Special EZ is a high-wall split air conditioning system designed for homeowners who want efficient cooling, useful heating, smart control, and a clean-looking indoor unit without turning the room into a noisy ice cave.

The DUALCOOL Special EZ replaces LG’s popular Standard Plus range, bringing together smart comfort features, quiet performance, and efficient cooling in a stylish wall-mounted unit.

While it is not the cheapest air conditioning option on the market, it offers enough practical features to make the price feel more reasonable, especially if you want a single system for both summer cooling and winter heating.

The range includes several model sizes, starting with the EZ09 at 2.5 kilowatts (kW) cooling and 3.3kW heating, moving up to the EZ24 at 6.6kW cooling and 7.5kW heating.

That means the right LG DUALCOOL Special EZ model will depend on the room size, the property’s layout, insulation levels, glazing, and how the space is used.

The DUALCOOL Special EZ includes several features designed to improve comfort, efficiency, and day-to-day usability.

However, what matters the most is that modern air conditioning is no longer just about blasting cold air into a room.

A good system should cool efficiently, heat effectively, help manage humidity, run quietly, and avoid using more electricity than necessary.

Key Features of the LG DUALCOOL Special EZ

Before you decide if the LG DUALCOOL Special EZ is worth it, it’s good to see what you’re actually getting for your money.

After all, this isn’t just a basic wall unit that blows cold air.

Its main features are designed around comfort, efficiency, quieter operation, and year-round use.

Dual Inverter Compressor

One of the best features is LG’s Dual Inverter Compressor technology.

Instead of turning on and off all the time, the compressor slowly adjusts its power to keep the room at a steady temperature.

This technology makes the room more comfortable, keeps things quieter, and helps save energy.

Cooling And Heating In One System

One of the biggest reasons to consider the LG DUALCOOL Special EZ is that it is not only an air conditioner.

It can also work as an air-to-air heat pump.

That means it can cool your room in summer and provide warm air in colder months.

For many UK homeowners, this is where the investment case becomes more interesting.

Instead of needing a fan for summer, a heater for winter, and a dehumidifier for damp days, a split air-conditioning system like this can do it all in one unit.

Smart Control And Voice Control

The LG DUALCOOL Special EZ includes simple voice control, allowing compatible AI speakers to recognise spoken commands.

This makes it easier to adjust the system without having to search for the remote, especially when you are already settled in bed, working from home, or managing several devices around the house.

Smart control is becoming an increasingly important part of home heating and cooling.

Just as smart thermostats help homeowners manage their central heating more efficiently, smart-enabled air conditioning can make room-by-room comfort easier to control around daily routines.

Whether you want to cool your bedroom before bed or warm up your home office before work, these connected controls make the system feel like a natural part of your home.

Auto Cleaning

The LG DUALCOOL Special EZ has an auto-cleaning feature that dries out moisture inside the unit after cooling.

This helps prevent smells and keeps the system fresher between uses.

But auto cleaning isn’t a substitute for regular maintenance. You still need to check the filters, make sure airflow is good, and look after the system to keep it running well.

For more details, check out our air conditioning maintenance guide.

In UK homes, where air conditioning gets used a lot in summer but less in cooler months, this feature is handy.

It helps keep things fresh day to day, while regular maintenance keeps the system working well.

Quieter Operation

Noise is one of the biggest concerns people have when buying air conditioning, especially if the unit is being installed in a bedroom, home office, or living room.

The LG DUALCOOL Special EZ is designed for low-noise operation, helping it run quietly in the background rather than becoming the main feature of the room.

For context, LG air conditioning systems with low-noise operation can run at around 20dB in their quietest modes, which is close to the sound level of a quiet natural area.

A whisper is typically around 25 to 30dB, a suburban area at night is around 40dB, a household refrigerator is around 55dB, and normal conversation is usually around 60 to 70dB.

That means a low-noise wall-mounted air conditioner can be much quieter than everyday household sounds when operating at its lowest setting.

This makes the LG DUALCOOL Special EZ a strong option for bedrooms, home offices, and living areas where comfort should not come at the cost of a constant mechanical hum.

However, noise levels can vary depending on the selected fan speed, room size, installation quality, and the system’s workload.

A poorly sized unit may need to run harder than necessary, making it more noticeable.

That’s why picking the right model and getting it professionally installed is just as important as the brand itself.

SEER and SCOP: How Efficient Is the LG DUALCOOL Special EZ?

When reviewing an air conditioner, two of the most useful efficiency figures are SEER and SCOP.

Jargon Buster: SEER (Seasonal Energy Efficiency Ratio)
A measure of an air conditioning unit’s cooling efficiency over a typical season. The higher the SEER rating, the more efficient the system is at cooling your home, which helps keep running costs low.

SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently the unit cools over a typical cooling season.

The higher the SEER rating, the more efficient the system is when cooling.

SCOP stands for Seasonal Coefficient of Performance. It measures how efficiently the unit heats over a typical heating season.

Again, the higher the number, the better the efficiency.

For the LG DUALCOOL Special EZ range, the SEER ratings range from 6.6 to 7.0, while the SCOP ratings range from 4.0 to 4.3, depending on the model size.

The smaller EZ09 model has a SEER of 7.0 and a SCOP of 4.0, while the larger EZ24 model has a SEER of 6.9 and a SCOP of 4.3.

In simple terms, an SCOP of 4.0 means the system gives you about 4kW of heat for every 1kW of electricity it uses.

A SCOP of 4.3 is even better, giving you 4.3kW of heat per 1kW used.

That is the key difference between an air-to-air heat pump and a basic electric heater.

A standard electric heater usually works at close to a 1:1 ratio, meaning 1kW of electricity produces about 1kW of heat.

Compared to basic electric heaters, the LG DUALCOOL Special EZ moves heat more efficiently, making it a better year-round choice for rooms that need both cooling and heating.

For cooling, the SEER ratings of 6.6 to 7.0 suggest strong seasonal efficiency across the range.

The exact performance will still depend on room size, insulation, glazing, fan speed, temperature settings, and installation quality.

However, these figures show that the DUALCOOL Special EZ is designed as an efficient fixed system rather than a simple cold-air appliance.

Is The LG DUALCOOL Special EZ Worth The Investment?

An Engineer’s View

“The benefit of a unit like the LG DUALCOOL is its versatility. Homeowners often forget that modern air-to-air heat pumps provide some of the most efficient winter heating available, completely transforming how you manage temperature year-round without relying on your boiler.”

– Rhys Powell, Engineer

Yes, the LG DUALCOOL Special EZ is a good investment if you want a reliable, efficient, and smart fixed air-conditioning system for daily use.

It’s best for homeowners who want a single system for both summer cooling and winter heating, rather than using separate fans, heaters, or temporary solutions. It is especially well-suited to:

• Bedrooms that become too warm in summer
• Home offices that need steady comfort throughout the day
• Loft conversions, garden rooms, and open-plan living spaces
• Homeowners who want a quieter alternative to portable AC
• Rooms where smart control and voice control would be useful
• Households looking for a more efficient long-term comfort upgrade

The efficiency numbers also back up why it’s a good investment.

With SEER ratings between 6.6 and 7.0 and SCOP ratings between 4.0 and 4.3, the LG DUALCOOL Special EZ is designed to do more than simply push cold air into a room.

It can also provide efficient heating, with some models delivering more than four times the heat output for each unit of electricity used under seasonal test conditions.

That makes it a stronger year-round option than a basic electric heater or a portable air conditioner, especially for homeowners who want a fixed system that feels like part of the home rather than a temporary appliance.

However, it will not be the right choice for everyone.

If you only need occasional cooling for a few days each summer, rent your property, or want the lowest possible upfront cost, a fixed split system may be harder to justify.

Final Answer: Should You Buy It?

Yes, if you want a smart, efficient, year-round heating and cooling system and are willing to invest in professional installation.

No, if you only want the cheapest way to cool a room for a few hot days each year.

For most homeowners comparing fixed air conditioning systems, the LG DUALCOOL Special EZ is a worthwhile investment, especially when comfort, quiet operation, smart control, efficiency, and long-term usability matter more than the lowest upfront price.
