Like any technology, ductless heat pumps need to be used properly and under the right conditions in order to achieve maximum value from them. And like anything in the internet age, ductless heat pumps are subject to all kinds of misinformation and misconceptions that can mislead consumers. Here are five of the biggest misconceptions being spread about ductless and mini split heat pumps.


Myth #1: They Are More Expensive To Run and Less Efficient Than Oil Or Gas Heaters

The use of electric heat pumps will actually save you between $1,000 and $2,000 annually in energy costs, making it one of the most energy efficient air conditioning and heating systems out there. The cost savings associated with split-ductless heat pumps is dependent upon a number of factors, including the efficiency, condition and location of the original equipment, energy type and climatic region.


Myth #2: Mini-Split Heat Pumps Collect And Distribute Bacteria

Most mini split heat pumps are equipped with filter systems and self-cleaning functions, so that bacteria and spores don’t have an opportunity to settle. Incoming air is purified in several steps. Large plastic filters which cover the heat exchanger, as well as electric filter collectors, can both be washed with soapy water. An internal fan insures that the heat exchanger dries completely, eliminating any chance of bacterial growth. Ductless mini split systems actually provide better air quality and remove more allergens than traditional systems.


Myth #3: Ductless Heat Pumps Are Only Suitable For New Construction and Not Existing Properties

While ductless heat pumps (like any new heating and air conditioning system), are more efficient in well-insulated new-build houses, they can still manage climate control and drive efficiencies in existing or older homes. In new homes mini-split heat pumps may be combined with other heating and air conditioning systems such as underfloor in order to make full use of all available space. But they are also a perfectly good option for older homes, especially when the homeowner wants to add energy efficient air conditioning as well as upgrade their heating system.


Myth #4: They Don’t Have A Long Life Cycle Because They Operate Twelve Months A Year

As long as they are properly maintained and serviced, ductless heat pumps have the same life cycle as traditional HVAC systems. Dirt, improper application and service, and lack of preventative care are the main reasons heat pumps fail, so it's important to monitor performance and schedule routine maintenance just as you would your car or any other major appliance you operate year-round.


Myth #5: Mini-Split Heat Pumps Don’t Work In Cold Climates

Hyper-Heat systems offer 100 percent heating capacity at 5° F outdoor ambient, and offer performance down to -13° F outdoor ambient, so they're the perfect supplement to an existing central heating system. Offering higher efficiency ratings than boiler-based systems, ductless heat pumps cost less to operate by maximizing the amount of heat generated from the energy consumed, so a ductless mini-split is not only an energy efficient air conditioner, it's also one of the most effective and energy efficient heaters out there.
