The advantages of ductless heat pumps

No need for ductwork. When homeowners don’t have ductwork, it can be very expensive to add central air conditioning or forced-air heating. Ductless systems are not only more budget-friendly because you avoid installing ductwork, but the installation process is easier.

Zoning your heating and cooling. Ductless units operate autonomously, so you can decide when and to what temperature different rooms in your house are heated or cooled. Your heating and cooling efficiency will notably improve.

Energy efficiency. By using ductless cooling and heating systems, you can reduce your home’s energy expenses while maintaining a comfortable temperature. These systems are efficient because the air is not lost through ductwork like traditional HVAC systems, so all the heated or cooled air goes directly into your living spaces.

No more window A/C units. Say goodbye to the inefficiency, hassle, and security risk of window air conditioning units when you install ductless heat pumps! Other benefits include no more light being blocked by window units. Also, no more easy access into your home for dust, dirt, pollen, and bugs.

How ductless heat pumps work

Ductless heat pumps are easy to change from heating to cooling mode with just the push of a button. You don’t need two separate systems! The outdoor compressor unit and the indoor air handler, called the evaporator, are both parts of a heat pump. They connect through tubing that has power lines as well as communications and condensate drain lines running through it.

Cooling: The compressor does what its name implies and compresses the refrigerant vapor so that it can circulate to the condenser. Here, heat from within the refrigerant is transferred into the surrounding air outside, and as a result, the refrigerant changes back into a liquid form. Afterward, this liquid passes through an expansion valve where its pressure decreases significantly. From there, it enters another coil, known as the evaporator, where indoor air is blown over said coils containing low-pressure coolants which absorb heat readily from said air; thus cooling it in turn. This newly cooled indoor temperature-controlled environment leaves through supply registers located throughout your house accordingly.

Heating: Reversing the closed-loop heat pump system in winter enables houses to draw heat from the outside air rather than trying to extract it from within.

The refrigerant works by first becoming a vapor under low pressure, which chills it significantly. Heat always flows from hotter objects to colder ones, so the refrigerant absorbs heat from its surroundings. The compressor then pressurizes the gas back into a hot liquid form once it has drawn all available heat out of its environment. This extremely hot refrigerant is then routed to your indoor coils via tubing, where your blower releases the built-up heat into your home.
