They sell anything that goes in a restaurant. This includes stoves too of course. These are commercial stoves. So, they do not recommend these for houses because they are too big and too much. As far as customer service is concerned, I called them on the phone and they picked up after one ring. Sometimes in the morning they are busy out front on a forklift loading and/or unloading trucks. It’s location is hidden and tricky to get to. Just take exit 9 and go east about a half mile. When you get to Mr. Zip which is at the first red light, take a right. It’s about one mile on the right but it is facing South so if you miss it, you will see it after turning around. I know I missed it three or four times before finding it. I will give them another chance later and if their responses are achievable in my dialect, I will look at this review again for a higher score. Thanks
