Testimonials
R.G. & S.D. Williams, Casebrook
“Three big ticks for any company is indeed a success story. Thanks once again, we really appreciated the service.”
Owen & June Thomas, Westmorland
“You were recommended to us and after making the initial enquiry we were totally confident in what was discussed and because of this did not enter into another quote.”
Matt Brackenridge, Mairehau
“The quality of work is brilliant, the heat pump is located as high as possible, the overflow/drainage pipe neatly runs down the outside wall, and the outdoor unit placed discreetly around the back.”
Margaret & Ross Heveldt, Strowan
“We wish to pass on our thanks to your staff. We found them extremely helpful, tidy in their work habits, considerate towards our wishes and really could not fault their workmanship.”
Margaret Close, Hogben
“The two technicians who installed the unit are a credit to your company. They did an excellent job and were most courteous and helpful. Ensuring that I understood how to use the remote, and that I had passed my “driving test” before they left.”
Pat Richardson, Conifer Place
