These are unsolicited comments received from Hart & Iliff customers.

"To the Office of Hart & Iliff: Thank you for always having the best customer service! Thank you for all the help and advice!"

"I would like to thank you for the installation of my new boiler. It was very timely and was certainly worry free for me. Please relay my thanks to your installation team for the nice job. Their work was careful and deliberate. I fully agree with the building inspector that they did a beautiful job. I am no plumber, but I can clearly see that their work is pristine!"

"Your technicians are always helpful and courteous. So are the ladies (and the boss) in the office. I am proud for my neighbors to see the H & I professional service techs in the clean H & I vans when they are parked by my house."
