Ya, you pay 2 times what the equipment install is worth then the gov't gives you next to nothing back. Great deal.
Here's a tip Sun, if you are planning on any equipment upgrades wait another 2years before you buy any furnaces or hot water heaters. The technology is mind blowing in the commercial market right now and will only get better for the residential market. I have recently worked with boilers that are 99% + efficient. The residential market is lagging behind a bit and is still costly but within a couple of years will drop and the technology will be better.
