They were called for an installation quote in the past & never responded to give a quote. My mother has had them come a few times because they are local. It was Dec. 24th when she called 1st, her heater quit. She refused to call Dec 25th because of Christmas. She & I called Dec 26th. It is now 1:30 pm Dec 27th and no one has contacted her. I am furious!!! My mother is 72 and in bad health.
