A ductless system is a versatile option that fits any space, whether for residential use or commercial HVAC applications. Whether you're adding a new room, upgrading an older home, or optimizing climate control in a commercial space, a ductless mini-split installation from Crystal Heating and Cooling is a smart investment.

It takes up very little space, improves indoor air quality, and lowers energy bills while offering precise temperature control for individual rooms.

What is a Ductless Mini Split System?

A ductless mini-split system, also known as mini-split air conditioner, is ductless because it's a heating system and A/C system that requires no ventilation work. It's a split system because there are separate indoor air handlers and outdoor units, and it's mini due to its compact size when compared to a traditional central air system.

A ductless mini-split system is the perfect option when you don't want to do ventilation work. It can do it all and is perfect for space conversions like an attic or garage, room additions, or even if you desire a boost in cool air for a room that’s always too hot or too cold. It can even provide comfort to one area or separate temperature control to several areas which is perfect for St. Louis homes where the temperature can vary widely throughout the year.

You can use a ductless mini-split system as part of a new system or to provide air conditioning services for an older home.  Whatever your specific needs, count on you can count on Crystal.

Considering a Ductless Mini Split System?

Running air duct and operating central air or heat for just one room doesn’t make sense. With a ductless heat pump, lower energy bills and improved comfort are possible.

  • Rather than cutting large gaps into walls or ceilings, ductless units require only a 3” hole to connect refrigerant lines between indoor and outdoor units.
  • A ductless system operates only as needed so you don’t pay to heat and cool the entire house.
  • Ductless systems filter dust, bacteria, and other allergens before it's circulated through ductwork.
  • Since conditioned air often escapes through leaks in ductwork, going ductless can lower your energy bills by up to 30%.

Ductless Heat Pumps Work Two Ways

Mini split systems can both heat and cool your home. For the most high-efficiency ductless solutions, we recommend Carrier brand ductless heat pumps.

Ductless Air Conditioner

When the air in your home is warm, the indoor unit (or handler) of a ductless heat pump blows that air over cold evaporator coils, then refrigerant absorbs the heat and brings it to the outside unit (the compressor).

Ductless Heating

While standard electric heaters create heat to warm your rooms in winter, a ductless heat pump pulls existing heat from the outdoor air into your home.
