Review of Grassers Plumbing and Heating

I got home from work at 3:30 my house was 57 degrees. I was having a meeting at my house at 7:00. I called Grassers they sent a repair man. He was there in 20 minutes. Thank goodness it was a small fix and the furnace was up and running! Thank you for your speedy service! By 7:00 my house was nice and toasty!!
