When our furnace started having issues I called a HVAC Technician. It turned out to be servicable but is suffereing from old age. I told the technician it's too bad the Fed Tax credit just ended.
That's true he said but our County and your Electric Co have huge rebate programs that still have money. The key is to have an Energy Audit that shows the house could be 25% more efficient and our County will pay 70% of the upgrade cost and our Electric Co will kick in additional rebates as well.
I especially like the fact that getting more efficient includes not only furnaces and A/C units but also windows, insulation and more.
For an devoted penny pincher like me this is great new and my Energy Audit will be done tomorrow.
