May Tag Refrigerator




Review of Grassers Plumbing and Heating

The guys that installed were great! The girl that waited on us at Grassers was helpful and informative! The refrigerator is terribly noisy, I want to give it a day and see, I will call if it stays this noisy! It is an extremely noisier that the 15 year old Whirlpool that was replaced!

Something else




Review of Grassers Plumbing and Heating

There was no call ahead to alert us that you were coming. You were lucky to catch someone at home


Response from Grassers Plumbing and Heating:

Good Morning Gene. I actually tried calling you on Monday to let you know we were heading over but our # shows up unknown so a lot of times customers don't answer. Instead of moving on and not coming I told our installers to swing by because I know you were wanting it installed right away. Glad we were able to catch someone and get you taken care of.

Great Service, Prompt Service, Fair Pricing & Extremely Professional




Review of Grassers Plumbing and Heating

As a Real Estate Manager for a major medical center in Chicago I deal with many vendors and contractors from every trade and I have high expectations with respect to service and value. It is refreshing to know that I can receive service and value of the same caliber 2 hours away from home in central Illinois. Grassers has met or exceeded my expectations on every occasion and I would highly recommend them to anyone needing plumbing or mechanical work.
