Is a mini split right for you?

Mini splits can be utilized for whole home heating and cooling, but are also a great fit to supplement your existing HVAC system depending on your needs.

Mini splits are increasingly being used in situations, such as:

Homes with costly electric heat (e.g., baseboard, furnace, wall heaters, electric radiant) that will also benefit from cooling. Older homes with no existing ductwork (e.g., radiators or baseboard heat) that have never had central air conditioning before. Existing homes with high fuel costs. Additions or outbuildings (e.g., shed, barn, garage) where extending ductwork or heating/cooling capacity is difficult. Spaces adjacent to unconditioned spaces where ductwork would be exposed to harsher temperatures (e.g., a guest room above a garage). New, high-efficiency homes, including ENERGY STAR certified homes. Older commercial buildings with no existing ductwork for air conditioning or expansions. Where hot or cold spots exist within homes including spaces which serve as home offices. Rooms require additional heating with a preference to reduce fossil fuel consumption from primary heating source. Buildings with an older central heating unit that would like to replace it with a whole home clean heating solution. Proper Sizing

Installing properly sized HVAC equipment for your home is essential to getting the best performance and comfort. A system that is either too large or too small for its intended space will struggle to meet your home comfort needs. Your HVAC contractor can help determine what sized system is right for your home. Your contractor should verify the proper size system for your home using a tool called "Manual J" - a calculation of the amount of heating and cooling your home requires to keep you warm in the winter and cool in the summer.

Cold Climate Considerations

Many new ENERGY STAR certified mini split models excel at providing space heating even in the coldest of climates, as they use advanced compressors and refrigerants that allow for improved low temperature performance. If you live in a climate where winter temperatures regularly dip below freezing, talk to your contractor to choose an ENERGY STAR certified unit suited to your particular home. When you ask your contractor for an ENERGY STAR certified cold climate ASHP, you can be confident that your new AHSP system will deliver the heating performance and efficiency benefits you expect on even the coldest winter days. A good contractor will work with you to determine the size and potential integration with a back-up heating system that will work best for your home.

Climate ASHP technology has improved significantly over the past several years, and many ASHP systems are capable of delivering heating capacity and efficiency at low outdoor temperatures. The ENERGY STAR certification requires third-party verified performance for low temperatures, testing ASHPs down to 5°F. Testing cold climate ASHP performance at 5°F ensures that your ASHP will provide all the heat you need to keep your home comfortable all winter. Your cold climate ASHP will continue working at temperatures below 5°F, but pairing it with a back-up energy source will heat your home the most efficiently when temperatures are even lower.

Take Advantage of Incentives

Air source heat pumps that earn the ENERGY STAR are eligible for a federal tax credit up to $2,000. This tax credit is effective for products purchased and installed between January 1, 2023, and December 31, 2032. Learn more at www.energystar.gov/taxcredits. Many utilities also offer incentives for installing ENERGY STAR certified ASHPs. Check with your local utility for more details or go to: www.energystar.gov/rebatefinder.

What else should I look for when buying a mini split?

Remember, even though these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills. Consider regular maintenance of your heating and cooling system to prevent future problems and unwanted costs. Mini splits are one of six high-impact improvements to your home that work together to deliver significant energy and cost savings.
