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.

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.
