Review of Grassers Plumbing and Heating

Going in to buy the fridge was a breeze. Heather was super friendly and very amazing. She definitely knows what shes doing when it comes to helping customers pick something out and has exceptional customer service skills. Delivery day, 2 guys came to haul out the old one and being in the new one. They were great guys. Very polite and friendly! If only all service people that came to your house could be like these two. They were very professional and funny at the same time. Made for a pleasant and easy delivery!
