Vic-Mar replaced our old furnace with a new Coleman furnace and installed central air condition on the system in Nov. 2009. The air conditioning unit, although tested by VicMar, never worked and after multiple calls, our tenants were forced to call another contractor who determined that the unit was defective and was able to have the whole thing replaced under warranty. As for the furnace, a defective gas valve prevented us from turning it on this year (Oct. 2012) and we discovered that the ignition has always been defective, since the unit no longer makes the racket it has always made when the gas valve opens. We tried contacting VicMar to address the problem, but could not reach them and had to call another contractor about the gas valve. We are not impressed with two pieces of defective equipment nor with the customer service VicMar provides. The one thing they did to our continuing satisfaction was to rereoute the duct work to provide better heat in two of our upstairs bedrooms.
