The outdoor heat pump must at least meet the government minimal efficiency standard of 13 SEER/7.7 HSPF, but you can also choose from several more efficient heat pumps that carry the ENERGY STAR rating. The gas furnace must meet the 78% AFUE energy efficiency requirements. Our heat pumps range from 13/8.0 HSPF to 20 SEER 10/HSPF, and our gas furnaces range from 80%-97.4% AFUE.

Most efficient options.

A high-end heat pump like the iQ Drive® Heat Pump features a sensor and thermostat control that is ready for dual-fuel operation. Because of its patented controller technology, it is not only the most energy efficient air-source heat pump available; it can operate at lower set points than other air-source heat pumps nominally rated at the same capacity. Translated, a 3-ton iQ Drive Heat Pump could be set to continue to run at a lower outdoor temperature than that of a typical 3 ton Heat Pump. This system also features extraordinary dehumidification during humid summers and extremely quiet operation. It is compatible with any of our iQ Drive Ready furnace or air handler products.

Mid-efficiency options.

Even if you are not in the market for the top-of-line dual-fuel system like the iQ Drive®, you can get a mid-efficiency system, like a 15 SEER Heat Pump with a 80 or 95.1% AFUE Furnace. Many of these systems also qualify for the Federal Tax Credit (U.S. only) which provides up to $1500 in a tax credit. Check with your local utility company to see if there are special rebates for installing high efficiency heating and cooling equipment. In the U.S., you can check out the Database of State Incentives for Renewables and Efficiencies (http://www.dsireusa.org) for information on incentives in your state.

Standard efficiency option.

If you can only invest in the minimum-efficiency systems, they are still up to 30% more efficient than most systems installed between 1992 and 2005. A standard efficiency system is not likely to be eligible for a local rebate nor is it eligible for the federal tax credit program. However, choosing a standard efficiency dual-fuel system over the standard efficiency furnace/air conditioning system will still yield savings in operating costs.

Is there a hybrid option for a packaged system?

Some locations use a packaged system instead of a split system. A packaged system houses the entire system (coil, blower, etc.) in one outdoor system. If you have a packaged system that heats your home through gas/electric or heat pump technology, you may want to consider our iHybrid. This all-in-one comfort system takes advantage of gas and electric heat to reduce operating costs.

A qualified contractor can help determine the right system for your home.
