Furnace went out overnight. Jim gas it fixed by noon.
Jim was outstanding. He took the time to explain everything to me and was so patient. We are very satisfied with them and will call them again.
Everything was done timely and well. The communication before and after our service was excellent.
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.
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!
Grenz is always very responsive. They give good solid advice to make repair decisions on. Work is done well and explained. I'm addition, they have always worked around my schedule and coordinated with the tenants of the property.
Came to fix my walk in freezer working great now. Saved our products.
On time, courteous, uses shoe covers inside, explained all checks and inspections clearly- confident our system is now ready for summer! Definitely recommend !
Came to location at the scheduled time to repair a non-working fireplace. Fireplace was repaired with parts that were brought up to unit with the tech on his cart. Very efficient repair process.
Cannot say enough goodl things about Jim or his company
They do a great job whenever we call them. They are always very friendly and take time to answer any questions we may have.
