"We have had many workers come to our house to do work for us and wish they all showed Merz’s professionalism. Merz deserves a big pat on the back."

"I want to compliment you for your staff at Merz. The young lady who answered the phone after 8PM could tell I was a desperate housewife –NO AIR CONDITIONING. The young man who made the service call certainly deserves a pat on the back. He was so courteous and efficient. Thank you!"

"Thank you for the prompt service I received on my furnace. It was very frustrating to hear it wasn’t working and me down in Florida. Again, Thank You."

"Friday afternoon your service tech determined that my old AC was shot. From that point on there were as many as four or five men at times getting my new unit installed. They were all very professional, courteous and evidently very knowledgeable in what they were doing. I was totally impressed in the short time it took them to replace the old unit and get us back up and running. I just wanted to share our family’s sincere appreciation for not only the quality of service but also the short time it took them to accomplish it. Thank you for providing our family with a top-notch service team. Please extend our appreciation to them as well."
