Residential Air Conditioning in Merton

Wimbledon Village sits on the hill above the town centre and is one of the most prestigious and expensive residential addresses in south west London, with a genuine village character that feels distinct from the rest of the borough. Wimbledon town centre and Raynes Park offer a broader mix of Victorian terraces, period conversions and newer apartment developments across the SW19 and SW20 postcodes. Mitcham and Morden provide a more suburban character further south, with inter-war semis and terraces that have long attracted families looking for more space within reach of central London.

With a wide range of property types from Wimbledon Village townhouses to Mitcham semis, air conditioning is a practical and growing investment for homeowners across the SW19, SW20, CR4 and SM4 postcodes.

We regularly install systems in:

• Bedrooms and master suites
• Living rooms and open-plan spaces
• Home offices and studies
• Loft conversions and extensions
• Garden offices and studios
• Conservatories and orangeries

Benefits for homeowners include:

• Quiet, efficient temperature control
• Improved indoor air quality
• Lower energy costs
• Heating and cooling from one system

Our engineers will assess your property in full and recommend the most suitable system based on room sizes, layout, insulation, building type and your individual comfort requirements.

Great service from everyone at I-HT. From the initial enquiry, quote and installation, everything was brilliant. The installers and electricians did a great job on the hottest day of the year, which included crawling around in our loft which must have been 40c ! They left everything very tidy. We are now enjoying cool air in the long hot summer.
Thanks again.

After thoroughly explaining how it would look both inside and outside the installation was very neatly done with no damage to the decor. We were shown how to use the remote and helped to download the app and shown how to control the unit remotely. We couldn’t be happier with the service

Really wish I’d had air con installed years ago. Finally went for it after a recommendation from my electrician. Lee came out really quick to do the survey even when in a heatwave. I was offered an installation date quicker than I thought as I was going for a single unit. I was pleasantly surprised with the price too.  Michael was a top installer. Can’t believe how tidy he left it. Was cleaner than when he arrived 🙌 genuinely kind and diligent with his work. Was such a good experience he’s coming back in August to fit an upstairs one. Can’t get a better compliment than that. 10/10 I-HT and the office team. Thanks ☺️ very much

I had I-HT install an air conditioning system at home, the guys who came round were great, very punctual and completed the install in around 4 hours and left the place clean and tidy. Installation was extremely neat and professional, and would recommend them over any other.

You may find cheaper quotes, but you do not want to cheap out when it comes to a quality job and on going customer service. On that note, they were not expensive - just a fair price for outstanding work and customer service.

A lovely, friendly and professional company to deal with and they're local too!!  Easy to book our service with them.  Engineer was on time, rang to say he was on his way as well.  He was efficient, courteous and gave some helpful tips about the air con unit.  No hesitation in using the company again next year for our service.  We'll done I-HT - top marks!!

I am just so impressed with this company.   From the initial site visit with Lee East which was informative, responsive to our requirements and extremely thorough, through to office staff and the installation of our aircon unit by Jim the whole experience has been stress free and excellent.   Lee came within 4 days of an initial enquiry and was very reassuring about what could be installed and where internal and external equipment could go (unlike a previous different company).  He sent a full quote with options for equipment and prices.  We went ahead with I-HT and paid a deposit on the phone and 2 weeks after the initial consultation the technician Jim arrived promptly at 8.30 and completed the install.  He was totally professional, cleaned everything beautifully , explained clearly and easily and how to operate the AC and was a pleasure to have in the house.   I really do recommend the company.

Beyond brilliant from first phone call, through installation, and beyond!
I don't have the vocabulary to express just how impressed I am with this company.
No pressure from then when we called, and no pressure after receiving the quote.
Curtis and Mikey turned up at exactly the time given for the installation, and they didn't stop working all day. They didn't even had a lunch break! They wouldn't even let us vacuum after as they didn't want to put us to any trouble!
The installation is perfect and we're so happy.
And the cost was inexpensive compared to other quotes!
Thanks so much to everyone :o)

Fantastic experience with I-HT for my residential install - I had 8 units installed; 7 in the house and 1 in an external garden room.

My first touch point was with Lee who came out to do a site audit and produce a quote for me. Lee seemed very knowledgeable, gave me some good advice, answered all my questions, and most importantly was incredibly patient while my wife and I debated the correct positioning of air con units in each room for what must have seemed like hours on end.

Lee’s quote was good and he was very responsive while iterating on it and tweaking it.

Electrician (Lewis) also came out to do a site audit. Spent quite a bit of time at the house with me weighing up the options and making a recommendation on the best approach. Again, really seemed to care about doing a decent job (and spoiler alert - he DID do a fantastic job on the day). He even tidied up some of the existing electrical works as he went and left the place looking better than when he started.

Installers Jim and Sam were fantastic. They were incredibly flexible working around our two babies needing naps etc, and they were just nice friendly guys. Jim also kindly moved one of the units after he’d installed it because I changed my mind about the location and refused to complain about this despite me saying it was okay and deserved. Nothing was too much trouble for them.

Received an aftercare call following the install.

The whole experience was just decent from start to end.
  
 
  
 
 
 
   
 
 
 

Commercial Air Conditioning in Merton

Wimbledon is globally famous for the All England Lawn Tennis Club and the Wimbledon Championships, and the hospitality and hotel businesses around the town centre experience a significant surge in demand every summer that few other London locations can match. Wimbledon town centre itself is a major commercial hub, served by the District line, mainline rail to Waterloo and the southern terminus of Tramlink. Merton Abbey Mills, a working historic site once home to a William Morris workshop, now hosts a craft market that brings a different kind of visitor footfall to the SW19 area. Mitcham and Morden each have their own well-established local high streets serving their residential communities.

We design and install commercial air conditioning solutions tailored to the individual needs of Merton businesses, whether you operate a hospitality or hotel venue near Wimbledon, a retail or independent business in Mitcham or Morden or a professional or commercial premises across the SW19, SW20, CR4 or SM4 area.

Commercial customers benefit from:

• Stable indoor temperatures throughout the working day
• Improved air quality for staff and visitors
• Enhanced comfort and productivity
• Efficient performance across multi-room or open-plan environments

We plan every installation around your building layout, operating hours and occupancy levels to minimise disruption to your business.

Types of Air Conditioning Systems We Install

We supply and fit all major air conditioning system types across Merton and the surrounding south west London area, including:

Split & Multi-Split Systems

A flexible option for single rooms or multiple areas. Split systems suit individual rooms well, while multi-split setups let several indoor units run from one outdoor unit. Multi-split systems are a popular choice across the larger townhouses and detached homes of Wimbledon Village, where keeping several rooms comfortable is the priority.

Wall-Mounted Units

The most common and cost-effective option for homes and smaller commercial spaces. Wall-mounted units are efficient, straightforward to install and provide strong airflow without taking up floor or ceiling space.

Ceiling Cassette Units

Fitted discreetly into a suspended ceiling, these units spread air evenly in four directions. They work well in offices, retail units and larger commercial spaces where balanced airflow and a tidy finish matter.

Floor-Mounted Units

A practical option for rooms where wall space is limited. These units sit low to the ground and deliver quick, direct heating and cooling, making them well suited to conservatories, orangeries and older properties common throughout the borough.

Ceiling-Mounted Units

Designed for long or narrow rooms where wall and floor mounting are not suitable. These slim units fix directly to the ceiling and provide strong airflow without taking up extra space.

We fit trusted brands including Mitsubishi Electric, Daikin, Fujitsu and Worcester Bosch.

Our Air Conditioning Installation Process

We keep air conditioning installation in Merton simple, transparent and well organised from start to finish.

1. Site Survey

We look at room sizes, layout, insulation and airflow requirements before recommending the right system for your property.

2. System Design & Quotation

You receive a clear, itemised quote with transparent pricing and no hidden extras.

3. Installation

Our F-Gas certified engineers fit your system safely and neatly, protecting floors and furnishings throughout.

4. Testing & Commissioning

We check airflow, temperature accuracy, noise levels and overall performance before we finish up.

5. Demonstration

We show you how to use the system and get the most from its energy-saving and timer functions.

6. Aftercare Support

We remain on hand for ongoing servicing and maintenance to keep your system running reliably for years to come.
