Our Customers Are Talking!

“The walk-in refrigerator at our food pantry was found to be wet and warm after hours on a Friday evening. The Mark IV emergency line was called, and our message was responded to promptly. A plan was agreed upon, and the technician arrived early Saturday morning to check things out. The issue was resolved quickly, and our walk-in was cooling off within the hour.”

-Tom B.

“We rented a soft-serve ice cream machine for our son’s graduation party. They were helpful when placing orders, and the machine and paperwork were ready when we picked it up. The machine worked great. They responded quickly over the weekend when we had a question when setting up. We will definitely call them again.”

-Eric & Julie F.

“I have been using Mark IV Heating, Cooling, & Refrigeration for many years and am never disappointed! They are responsive and knowledgeable at all points of contact.”

-Carol A.

“Excellent, honest, professional service. A different service provider told me that the entire system needed to be replaced. Steve, however, spent the time diagnosing the issue and providing affordable recommendations.”
