Great experience

Paula from Waukesha, WI

Called to get an estimate to replace our furnace (which wasn’t working). Jim was great. He got the furnace running, explained all our options for replacement, and was so good about going over everything with me. Very pleased and will definitely be using Grenz going forward.

Excellent Service!

Bobbi from Waukesha, WI

We couldn't have asked for a better company to replace our furnaces. We reached out to three companies for a quote - all were good, but Grenz went above and beyond. First to respond to our request for a quote, first to provide the actual quote, and took the most time to work with us to find the right furnace solution. The installation was perfect, and now that the cold weather has hit - we can confirm we're 110% happy with our new system. Thank you to Jim and team for such great work!

Great service and advice at a fair price
