  • Brilliant service indeed! I know nothing about A/C units but was talked through all the options available and came to the decision of the 2.5kwh split unit and it’s perfect for my garden office/mancave. The installation was smooth and tidy! Very professional company and will definitely be using them again for future projects. Highly recommended 👍🏻

  • Very impressed with the professionalism and dedication this company has given offering a great service from the first enquiry through to fitting our new units. Emails are answered quickly, estimates were accurate and prices were reasonable. The team that fitted our units were very tidy, and the work carried out was neat with the trunking required fitted with particular care. They left the job clean and tidy, I would have no hesitation recommending Jamie and his team 👍🏻 Looking forward to wonderful cool bedrooms this summer!

  • Jamie and his team are 1st class from start to finish. I had 3 AC units installed and everything from initial contact and survey, through installation, to commissioning were excellent. Great communication, good advice, friendly and knowledgable team, quality products. I would highly recommend.

  • Had a 2.5kwh split unit installed in my garden office. Was an excellent service from the initial quote to final installation. Every question I had was answered politely no matter how stupid! On the day of installation the engineers turned up on time, did a great job and left the site extremely tidy. Even offering to mop the floor due to the mud situation.

  • We had a faulty upright display fridge, Jamie was really responsive and friendly to deal with. Arrived on time and fixed the issue immediately. The service was excellent from start to finish. I’ll be recommending this company and using them again.
