I am writing to commend your employees... on the professionalism displayed during the installation of our heating & air system... They explained the installation process throughout the day and were kind enough to answer the numerous questions of our two small boys...
Sincerely Michelle & Kevin Witcher
Thank you for all your help in getting our new A/C system replaced in our home... It is not often that everything goes according to plans and job is well done... We would not hesitate to refer you and your company to our friends and family... You don't know how much this meant to have a job done to our approval...
Respectfully Andy and Lisa Steger
...I am writing this letter because I feel that service in today's day and age is lacking in many corporations and it is nice to see a company go the extra mile to help a customer. I realize that this is a very busy time of year for your company and I want to thank you for making sure that we were taken care of promptly. We hope to be able to refer some business to ETC.
Thank you Ruben and Misty Daley
I wanted to take a moment and recognize three of your employee...for their work. I am well aware that all too often service organizations only receive communication when there are problems. At all times, each of these individuals acted very professionally... I would not hesitate to recommend or use your service again.
Sincerely Brian Sommer
I wanted to let you know what a wonderful job ETC did for us in putting new furnaces and air conditioning units in our home. The crew that was assigned to our house were extremely tenacious and conscientious... I would be pleased to recommend your company to anyone who asks. In fact I have recommended your company to one of my co-workers...
Sincerely Ann Waters Beytagh
This letter is to inform you of what an exceptional job Chris Goolsby did with the installation of my home's new air cleaning system. Over the past year I have been remodeling my home and dealing with many contractors. My experience with ETC has been by far the most pleasing...

It's my belief that we all take time to be critical of things, but far too few of us take the time to say, "Job well done".

I've always been impressed by the honest and professional service you personally have given me, and Chris Goolsby fits your mold...

Sincerely Neil Weinreb

I personally wanted to let you know how much Haggar Clothing Co. and I appreciated the hard work and dedication your guys gave to us during our a/c nightmare of our 65 year old system... Keep up the good work and I look forward to working with your guys again.
Sincerely Ray Stephens

This is just a quick note to express my very sincere gratitude to Chris Goolsby...for all their efforts towards making my air conditioner run!..

These gentlemen saved me, my birthday, and a wedding shower that I hosted today - Bless you! They both worked miracle w/ my rather old A.C. unit. I would and am currently recommending ETC to anyone within earshot. Thank you!

P.S. The dispatcher was very helpful. Many thanks for working me in.
