Eco-Friendly Cooling: Benefits of Pairing a Small Wall-Mounted AC with an Air Heat Recovery Unit

September 11 2025by Maximum Climate Control

London is naturally a temperate region with a mild climate, more prone to heating needs, but things are changing. The city’s summers are getting hotter, where it is not unusual to have heatwaves of up to 40°C. This leads to a growing demand for “cooling needs” and increased sales of air conditioners.

So if you are a homeowner navigating the options of the best wall-mounted air conditioner for sale in London, give a thought to its environmental impact, too. Why? Because climate change is real, and it’s one of the reasons why you need to install an aircon in your London home in the first place.

It makes all the sense to have your small air conditioning unit wall-mounted with an air heat recovery unit for a more eco-friendly cooling process. The HRU reduces the amount of hot and humid outside air that enters unconditioned spaces so that your AC doesn’t have to fight as hard, particularly during muggy UK spells.

Mainstays of Pairing an Air Heat Recovery Unit with Your Home AC

The first thing that most homeowners do to make their home cooler is find the best wall-mounted air conditioner for sale in London.

As a standalone device, it works through “targeted” cooling. New Daikin and Toshiba models also have dehumidification features among many others that improve the air quality of your indoor space. However, whenever fresh air is brought in from outside through open windows or extractor fans, much of the cooled air’s thermal advantage is lost.

The mainstay of pairing your home air conditioner with an air heat recovery unit is that it “recovers” the thermal energy from the outgoing stale air and uses it to pre-condition the incoming fresh air and deliver optimal ventilation. Your home can be warmer in winter and cooler in summer.

Without the HRU device, the AC will have to take all the stress alone and, in turn, need more energy. Together, they offer efficient cooling, better air quality, quieter operation, and lower running costs, without the clutter of a bulky kit.

At Maximum Climate Control UK, we see this combination working brilliantly in apartments, garden offices, loft conversions, and retrofit projects where floor space and electrical capacity are tight but comfort expectations are high.

Getting Your Small Air Conditioning Unit Wall-Mounted with an Air Heat Recovery Unit

Positive about integrating your wall-mounted AC with an HRU? You will find several variations in specs and configurations to choose from, including cooling capacity and features like air purification or smart controls.

We are Daikin D1+ Premium partners in London, widely working with Daikin’s air heat recovery unit (VRV/VRF) systems, as well as air source heat pump chillers. We can help you design and install an aircon in your London home with HRU integration, ensuring minimal disruption and maximum efficiency. Below are the common types of residential properties we recommend HRUs for:

• Flats and maisonettes where planning or lease conditions make exterior changes tricky – many modern condensers and façade kits are designed to be discreet.
• Garden rooms and home offices, where year-round comfort is necessary but full ducted systems aren’t practical.
• Loft conversions with tricky rooflines: short duct runs for the HRU and a single wall bracket for the AC keep things elegant.

We also work with commercial properties, offering personalised system setups. Whether you want to improve the energy efficiency of your property or reduce operational costs, Maximum Climate Control is your trusted destination.

Leading brands like Daikin and Toshiba are heavily invested in making their products more and more eco-friendly, and enhancing energy efficiency is one of the primary ways to do it.

We at Maximum Climate Control, as a leading air conditioning contractor in the UK, often find that the term “energy efficiency” can confuse consumers. Several specs go into the concept – performance data, for example, SEER ratings, seasonal energy consumption, and load-matching capabilities. Not all devices have the same features.

Customers need to make an informed choice about the system configuration that truly maximises efficiency. That’s where we come to the rescue with our expert guidance throughout the scopes of supply and installation, as well as integration.
