For homeowners in Crestwood, MO, seeking precise, energy-efficient heating and cooling without the need for extensive ductwork, ductless mini-split systems offer a compelling solution. Hely Heating and Air Conditioning provides comprehensive ductless services, from initial consultation and professional installation to reliable repair and routine maintenance, ensuring your home remains comfortable year-round.
Ductless mini-splits are comprised of an outdoor compressor/condenser unit connected to one or more indoor air-handling units via a small conduit that runs through your wall. This system allows for targeted temperature control in specific rooms or zones, offering flexibility and energy savings compared to traditional central air systems, especially in homes where installing ductwork is impractical or expensive.
Since 1969, Hely Heating and Air Conditioning has been a trusted provider of HVAC solutions throughout the St. Louis and Jefferson Counties, including the Crestwood area. Our deep understanding of local climate needs and home types allows us to recommend and implement the most effective comfort systems for your property.

Benefits of Ductless Systems for Crestwood Homes
Choosing a ductless mini-split system for your Crestwood residence comes with several advantages that can enhance your comfort and potentially reduce your energy consumption:
- Zoned Comfort: One of the primary benefits is the ability to create independent temperature zones. Each indoor unit can be controlled separately, allowing you to set different temperatures in different rooms or turn off units in unoccupied areas. This is ideal for solving hot and cold spots, managing comfort in multi-level homes, or catering to individual preferences within the household.
- Energy Efficiency: Ductless systems are generally more energy-efficient than window units or electric baseboard heaters. Many models feature inverter technology, which allows the compressor to adjust its speed based on the heating or cooling demand, consuming less energy than traditional systems that cycle on and off. This efficiency can translate into lower monthly utility bills for Crestwood homeowners.
- Improved Indoor Air Quality: Because ductless systems don't rely on ductwork, they bypass a common source of dust, allergens, and mold accumulation found in ducted systems. Indoor units typically include multi-stage filtration, helping to capture particles and improve the air you breathe inside your home. Our services related to Indoor Air Quality can further enhance your home environment.
- Quiet Operation: Both the outdoor and indoor units of ductless systems operate quietly compared to traditional HVAC units. The outdoor unit is typically less noisy than a central air conditioner, and the indoor units provide comfort without the loud whoosh of air associated with ducted vents.
- Easy and Flexible Installation: Installing a ductless system is far less invasive than adding or modifying ductwork. The connection between indoor and outdoor units requires only a small hole in the wall. This makes ductless systems an excellent option for existing homes without ductwork, room additions, converted garages or attics, or simply to provide comfort to a single room or area that needs supplemental heating or cooling.
- Heating and Cooling Capabilities: Most ductless mini-split systems function as heat pumps, providing both efficient cooling in the summer and effective heating in the winter. This makes them a versatile solution for year-round comfort in Crestwood's varied climate.
