``I was extremely pleased with both the new boiler and the engineers ( Craig and Adam ). AHS service was outstanding and I was very pleased with the plastering ( required after removal of the old boiler ) and the way everything was left neat and tidy.``

Reverend Savage - Hampshire.

``We are delighted with our new boiler it is really efficient. The team of men were so respectful of us and our home. They were so hard working and were always early and cleaned up each day. We couldn’t recommend them more highly. Thank you``

Lesley & Eddie

``Phoned one day with a request for a boiler service, and a leaking pipe at the back. The engineer came a day later. Shoes off at the front door, Craig was very polite and efficient and sorted the problems, and was able to think outside the box to solve the fact that we had a sheared off bolt preventing an emissions test necessary for the service. Very impressed.``

D Witt

``We were very happy with 2 jobs carried out by AHS in the past month. The engineers really know what they are doing and they worked very hard to make sure both our boilers worked. They are also very polite and friendly.``
