Airtech was very professional from start to finish, very welcoming, Philip was a gentleman. Very knowledgeable and knows about Air conditioning very well, he took his time with me, was very patient with me.
Staff are also very welcoming, every staff member made sure I was looked after and comfortable.
I needed a new Air conditioner as my previous one let me down from a well known company, if it wasnt for Philip and his team, I would be still suffering in this heat. I will definitely use their services in the future. Keep up the great work Airtech, 10 out of 10.

I recently hired Airtech to install multiple shower pumps in our commercial property, and the entire process was handled seamlessly. From the initial site survey to the presentation of detailed options and a prompt, clear quotation, everything was managed with professionalism. The installation, carried out by Daryl and Adrian, was completed to a high standard they were courteous, professional, and showed great care for our listed building. I've relied on Airtech for many years for air conditioning, plumbing & heating maintenance, and they consistently provide excellent service and great value. Thats why they remain one of my most trusted suppliers.

Excellent service and help from Lizzie who went above and beyond to accommodate everything we needed. We were working to a tight deadline but she ensured everything was completed on time, even with lots of changes to the schedule. Was always available on email and nothing was too much trouble - massive thanks Lizzie for assisting me with getting everything completed on time!

My aircon install was a bit unusual as it spanned over 2 years and yet the installers worked around this no problem. They were extremely helpful in planning pipe runs and choosing suitable locations for the indoor units.
They worked very efficiently and got everything installed and working perfectly.
One of the best companies I have worked with in my multi year building project, highly recommended.

Really great service from the initial call, booking process to both technicians on the day. Very professional. Care taken in the property. Both clearly very knowledgeable with experience. Start to finish was a very easy process. Not always the case with general household maintenance/repairs! Needless to say, would recommend without hesitation and will be using again.

Thank you to Ollie who went above and beyond on Wednesday to make sure my air conditioning was ready for the summer. He took apart the unit and took all the components outside to be cleaned. The engineer was also early and made sure his working area was clean and tidy. I have requested that he comes again to do my yearly service. Thank you Airtech for the great service.

Philip is an absolute gentlemen. I rang up to find out about all the latest green possibilties for our new build. Philip came across as very honest: he gave the disadvantages, real warts and all and even talked me out of some very expensive fads I was hoping for, contrary to his own interests, as being unsuitable for what we are looking to achieve.
It is a shame that more people aren't like Airtech. You can be sure I'll be coming back to them when I have rethought my plans as he gives honest advice from the customer perspective, not the hard sell

Joe and his team were great from the start with the quote to the finish. Joe listened to our requests and what we wanted from the ac and helped us choose the suitable unit for us. They were very thorough and paid attention to aesthetic along with functioning and made sure it looked as good as possible along with effective. They even cleaned afterwards. Great job! Absolutely recommend! Thank you so much

Airtech installed a new Daikin 3-way multisplit system at my property. The job was excellent from start to finish. Before starting, the MD Philip did a very thorough site survey himself, going over every detail with me carefully. Then he brought his engineer to plan the pipe and cable runs, and size the equipment etc. The actual installation took only two days, and was done to a very high standard. I don't often write reviews, but it was clear to me that Airtech were a company that cares deeply about the quality of work they do, and enjoy their work. Strongly recommend this firm.
