Benefits of Ductless Mini Split Systems

Ductless mini split systems provide a number of benefits for homes in the O’Fallon, IL area, including:

No Need for Ductwork

As their name suggests, ductless mini splits don’t require ductwork. Installing ductwork requires a large amount of construction throughout your home and can significantly increase installation costs. A ductless HVAC system is more cost-effective and less invasive.

Healthier Indoor Air Quality

Not only will ductless heating and cooling equipment make your home comfortable, but it will also improve your home’s air quality. That’s because the system’s highly efficient filters allow less dust and pollen to circulate in your space. The absence of ducts also limits the amount of dust and other contaminants from finding their way into your living areas. Ductless mini split systems allow you to feel more comfortable and breathe easier!

Zoned Heating and Cooling Systems

Because ductless mini splits create separate temperature control zones, you can adjust the temperature in each room or zone, if desired. If your son likes the temperature warmer at night and your daughter prefers it cooler, you can make both of them happy by separately controlling the temperature in each room.

No Major Renovations

All that’s required to install a ductless mini split system is a 3-inch hole. Our HVAC experts can connect the indoor units’ cable to the outdoor condenser, meaning that no major construction is required. Installing a ductless mini split system is quick and easy!

Zero Energy Loss

According to, it’s estimated that 20 to 30 percent of conditioned air is lost through the duct system because of leaks, holes and poorly connected ducts. Without the use of ducts, ductless mini split HVAC systems provide efficient heating and cooling with zero energy loss.

Your Current Unit Has Decreased Airflow

Your Mini Split Unit Smells Strange

Your Energy Bills Are Climbing

A great perk of having a ductless HVAC system installed is the energy efficiency these units provide. So, if bills begin climbing sharply and unexpectedly, your unit may be working harder than it should. A professional can assess both the indoor units and the outdoor condenser for damage.

Your Mini Split Is Loud and Making Strange Noises
