Air Conditioning Installation Richmond

Air Conditioning Installations from £1300 – 0% VAT

The London Borough of Richmond upon Thames is considered as one of the most beautiful and greenest corners of the capital. Bisected by the River Thames, its architectural identity is deeply prestigious from the historic, cobblestone lanes and grand Georgian townhouses surrounding Richmond Green, to the iconic Victorian terraces of Twickenham and Teddington, the leafy arts and crafts homes of Barnes and Kew and the exclusive mansions hidden within the Coombe Estate and Hampton. Because of the variety of property types in Richmond a single standard type of air conditioning installation for every property just cannot be applied. We offer free quotation visits throughout the borough including Richmond Town Centre(TW9), Kew(TW10), Twickenham(TW1) Strawberry Hill (TW2), Teddington (TW11), Barnes (SW13) Morklake (SW14) and Hampton (TW12) where our experienced engineer familiar with Richmond’s specific characteristics, can inspect your property and suggest you the best air conditioning solution either via a quick video call or an in person walkthrough.

Fully Certified Air Con Installations Built for Richmond’s Heritage

We at Efficient Home Energy are proud provide professional air conditioning installation services in Richmond whether your property is along the busy Upper Richmond Road (A316), near Twickenham High Street or right on the banks of the river.

Navigating Richmond’s 85 Conservation Areas

Richmond has 85 designated Conservation Areas with the highest amount of protected character zones in southwest London with nearly a thousand Grade II listed structures. From Barnes Green and Kew Green to Richmond Riverside and the hills of Richmond Hill, Richmond’s Council has very strict restrictions to protect the borough’s visual identity and architecture.

The borough is identified by its multi story Georgian townhouses or a protected Victorian character cottages with premium value. However, usually these properties have loft conversions that trap heat during heatwaves.

To be compliant with Richmond Council’s planning guidelines, our engineers usually suggest fully concealed ducted air conditioning systems and internal water cooled systems. These system options allow us to install your air conditioning without mounting any trunking or visible outdoor condenser unit to historic exterior brickwork, protecting your street facing exterior completely.

Micro Precision for Air Conditioning Installations on Period Timber and Brickwork

Another major characteristic of Richmond’s properties is its fragile, centuries old masonry and original timber framing. Air conditioning installations on these materials needs to be carried out with complete delicacy and specialised engineers.

Our engineers, acknowledging the fragility of the materials, use diamond-tipped core drills at a precisely controlled and slow speed to cleanly route pipework through historic brick or stone without causing structural shock or cracking. Additionally, where external units are permitted we suggest multisplit unit installations and we focus on ground level placement where we discreetly tucked behind garden walls, rather than the front exterior of your property.

Why People In Richmond Choose Air Conditioning?

Richmond has a very unique geographical characteristic as its extensive riverfront geometry and rich green riverside canopy. Multiple premium local properties face directly onto the River Thames or are located alongside the massive, lush green extent of Kew Gardens, Richmond Park and Bushy Park.

While being close to the river and green sites give your property beautiful views and an idyllic lifestyle, it also introduces a highly specific localised climate problem during the spring and summer months: The Wisteria-and-Waterway Greenhouse Trap.

Properties facing the river suffer from intense sun reflection, where the sun’s rays reflect on the river and pour a direct head on the property rising the indoor temperature significantly. At the same time, the big extent of the parks around the river, creates an immense local humidity. Especially when a heatwave hits, this heavy moisture air goes directly into the borough’s historic properties.

Standard household fans simply mix this heavy, humid air around. Air conditioning acts as the ultimate equaliser. It doesn’t just move air around as it has a dehumidification cycle that pulls out the heavy moisture every hour while dropping the temperature of the room.

While Richmond’s status as a green paradise is its biggest draw, it can also be an absolute nightmare for hay fever sufferers. The big amount of mature oak, horse chestnut and plane trees across Richmond Park and the world-renowned botanical reserves at Kew means that local pollen counts skyrocket during spring and summer.

The modern air conditioning units we install, solve this entirely as they have advanced filters that actually filter the air before it gets to your property. That allows you to keep your windows closed and have the air conditioning continuously so you can enjoy a perfectly cooled, fresh home all spring and summer without ever opening a window to let the pollen in.

While the northern part of the borough has great train connections and London Underground links (District line and Overground), parts of Richmond, Kew and Twickenham sit directly underneath the arrival and departure flight paths for Heathrow Airport. Noise pollution makes the window solution during summer not ideal, when having an air conditioning allows you to have your windows shut and keep the noise on the outside.


Air Conditioning Benefits Throughout The Year

  • Reduce Your Winter Bills: Richmond’s historic period townhouses have big rooms and drafty single glazed windows that cost a fortune to heat using traditional gas boilers. Because our modern air conditioning units are actually highly efficient air to air heat pumps, they can heat an individual room almost instantly. This localised zoning means you only pay to heat the room you are actually using and keep your winter energy bills under control.
  • Perfect Climate Control: With the various functionalities of an Air conditioning system, you can cool, heat, dehumidify and filter the air in any room of the house letting you maximise every single square foot of your property, 365 days a year.
  • Helping to Reduce Humidity and Dampness: Due to the historic, high value nature of many Richmond interiors, properties often house valuable antiques, original oil paintings, and fine timber instruments like grand pianos. Large swings in summer humidity and winter drafts can warp wood and degrade canvas. Our systems keep your indoor humidity and temperature completely stable all year round, protecting your investments.

How does air conditioning work?

Air conditioning systems remove the unwanted heat in a property and replace it with cooler, dry air. As the air conditioning systems we install are air to air heat pumps, you can use it as heating as well, where it just reverse the cooling circle. With heating, it works in the opposite way by providing heat inside your property. 

Do I need planning permission to install my air conditioning units in Richmond?

It is very unlikely that you would need to apply for planning permission to have an air conditioning unit installed in your property. However, because Richmond has a massive 85 Conservation Areas, along with strict Article 4 directions that remove permitted development rights for extensions and external alterations, standard outdoor condenser on walls or roofs are tightly restricted. We would recommend you to check with your local council or freeholder to be sure before we carry out an installation. 

Do I need to do anything before the installer arrives?

We kindly ask that you clear all areas where the installation will take place. This is inclusive of the area surrounding the wall where the interior unit will be fitted and also on the exterior where the external unit will be installed. This will allow the engineer to begin the work from the point of arrival, keeping the installation swift and efficient. 

What’s the cost to install an air conditioning unit? 

We offer a complete installation service starting from £1700. Prices vary depending on size and complexity of the installation, the units we install, the size of the installation and also the specific unit model you decide to go ahead with.

How long does installation take?  

A single unit installations for domestic properties can usually be carried out in a single day. Bigger installations of multiple units may require longer. Our engineers will always advise you on the length of the installation during the initial consultation after inspecting your property. 

Are air conditioning units noisy? 

Modern units typically function with hardly any noise pollution and will go unnoticed.  

Will an air conditioner affect my energy bills? 

Yes, Because our modern air conditioning units are actually highly efficient air to air heat pumps, they can heat an individual room almost instantly. This localised zoning means you only pay to heat the room you are actually using and keep your winter energy bills under control. 

Can I remotely control my air conditioning? 

A lot of modern systems now come with Wi-Fi or smart controls, allowing you to adjust the temperature from your phone or tablet, even when you’re not at home. 

How long will my air conditioning unit last? 

Your system can last up to 10-15 years with proper installation and maintenance. All our units come with a warranty.  

Can air conditioning help with mould and dampness?

Had a EPC assessment undertaken by Efficient Home Energy. It was easy to book and the assessor arrived on time. He undertook the work quickly and I received the report later the same day. I’m happy to recommend their service.

Great company to do business with and very efficient. I found their number on the internet and after informing them of the units that we had they came back with a very competitive quote. We had been using another company but the owner decided to move to Bristol so had to find someone else. Very lucky that the search engine found EHF and Ellie who I spoke to sent the quote virtually within 1 hour of conversation. The technician who was Alexander came as promised between 8.00 am and 11.00 am and carried out a full check and clean on the 3 units and sent us the reading for all within 2 hours. No problems and all filters etc cleaned and batteries check in remotes etc. We will certainly be using EHL again. Thank you so much for a Efficient service ! Will recommend them to our friends that have air conditioning in their homes.
