- Heating by burning a fuel is inherently inefficient. High-efficiency furnaces have components that are better designed to get more heat out of the combustion process, Dream Group’s Lunsford says
- Hire an HVAC contractor to calculate the size of the equipment needed for your home. Beware bidders who take a one-size-furnace-fits-all approach. Air source heat pumps and advanced main circulating fans may also qualify for the tax credit—check energystar.gov for the latest guidance.
- Don’t rely solely on contractors who may not know the details or who promise their products will get the credit in order to sell you a new system.
- Technically, you can replace either a furnace or a central air-conditioning unit and be eligible for the tax credit. Practically speaking, you’ll likely have to replace both for the A/C to qualify, says Enesta Jones, a spokeswoman for the U.S. Environmental Protection Agency.
- Most homes have split systems made up of an outdoor condenser and compressor that are connected to an indoor air handler that’s part of the furnace. Split systems must have a SEER rating of at least 16 and an EER rating of at least 13. The higher the rating, the more energy efficient the unit. A package A/C system, which houses all of its components outdoors, requires lower ratings.
