Please pass on to "the Powers at be" at Delta, my appreciation for the excellent job done yesterday by Paul and his colleagues, when they installed our new air conditioning system. It was very nice to wake up this morning to a house that was pleasantly warm.

We've been meaning to write to you to tell you how happy we are with the system. Firstly of all it just works so much better than the old system, it is quieter and warms up the house so much more quickly than I believed it could. Frankly I didn't expect it to work so well. Your staff whilst they were installing were very pleasant, business-like and easy to have around. So thank you for your advice re the installation, and for doing it so well.

Please thank David and son very much for their hard work. I appreciate their commitment to a job well done.

I recently purchased a new house with a system already installed by your firm some time ago. I organised for a serviceman to come to our house, he was efficient and had comprehensive knowledge & he greatly impressed me. I wish to pass on this wonderful customer service experience.

I am writing to thank you for the excellent service that we have received from your organisation, over the past few months. Your technician has been outstanding in his performance, quite often in extremely testing conditions, his courteous manner and positive attitude are a credit to himself and your company. Nothing is too much trouble for him, very reliable and quick to follow up on any promises he makes. Thank you again for your great service. M Dalgleish.

I would like to express my sincerest thanks and gratitude for the work you have done for me. It is such a pleasant change to receive some good old fashioned friendly service and your company has that in abundance. I realise that at this time of year you are very busy so I really do appreciate the effort involved to ensure I had some heating so quickly. Thank you so much.

We had tried another installer who told us our job could not be done. Then an ActewAGL rep who called to see us referred us to you. Your willingness to help sold us. Then it was all systems go. A good job, well done and it works so well.

I rang last week to say how pleased we were with the recent installation of the Split Systems in our Business Offices and Community Relations Office. The work was completed with the minimum of interference to staff and under extremely difficult physical conditions of extraordinary heat. I would like to thank your team for their persistence in working long hours to make sure that the equipment was up and running before they left on the Friday, more particularly as we had caused them some delays and inconvenienced them and the electricians.

Thank you so much for your prompt and professional service (with a smile too). It has been blissful coming back to a warm cosy house. I'll most certainly be recommending you to my customers and friends.

We would like to express our sincere appreciation to you and your staff for the manner in which you went about our installation. Your responsiveness during the sales process to ensure the system met our particular needs was fully professional and your pricing was very competitive, such that we felt full confidence in placing the order with you. The early scheduling of the job to get well ahead of our deadline was impressive. The installation team arrived dead on time and were all dedicated, skilled and hardworking; they also responded to us, as clients, with utmost courtesy. The end result is one we are very happy with. Would you please accept our thanks and convey our appreciation to all staff involved. Please be assured we would have no hesitation in recommending your services to any other potential clients.
