I had a family heating system installed in my brother's mobile home. There were 3 guys that came and I watched them work. Very nice people. They worked professionally, cleaned up after themselves, and were very polite. I didn't have time to shop around, so I took the price as is and trusted that he gave me a good price on the basis of a previous experience I had in which he gave me a good price. It's a very good company with nice people. Different people have different experiences, but for me it was all good.
