Nothing but great reviews from us. From the ease of an on-line work inquiry to the actual install of a new furnace, the process was seamless and a great customer experience. Not all HVAC install companies are equal; it pays to get an estimate for service from Grenz. Quality products and experienced, knowledgeable staff who truly care about the customer and needs. After having various HVAC companies service us for 20 years, we're 100% satisfied and sticking Grenz Service company.

Karisa from Hartland, WI

Jim was amazing explaining what could be wrong and what to do to prevent anything from happening in the future for our icemaker. He gave us options and explained everything in detail. He also coached me on another refrigeration system in the home. He definitely had the teacher attitude and was a fun guy to talk with!
