Many customers ask about tax credits and rebates that may be available on air conditioning units and furnaces. So I thought I would post the 2011 tax credits that are available from Energy Star for HVAC applications. A few include $300 for a new central air conditioning system, $150 for a new natural gas, propane or oil furnace and $150 for a new gas, propane or oil hot water boiler. Below are screenshots of the current tax credits available. Just click on any and it will take you to the Energy Star website for more details and how to apply.
