Elite should not be in business. They installed a boiler system in my house 3.5 years ago and used the worst product on the market - Quiteside. This product is so bad it is not even carried or supported by the manufacturer any longer. So my system died, needs a new heat exchanger, after only 3 years. I called Elite 3 times to get them to service this and they wouldn't even return my calls. Elite only cares about doing initial installs and then they run for the hills. You should stay far away from them.
