Flexible Comfort for Every Room and Every Season


Living in Missouri  and Illinois means experiencing all four seasons—and sometimes all in the same week! From hot, humid summers to icy winters, homeowners need heating and cooling systems that can adapt to changing weather. That’s where   mini-split systems shine. At Arco Heating & Cooling, we specialize in mini-split installations tailored to the unique needs of homes across the Midwest.


What Is a Mini-Split System?

A mini-split system is a type of ductless HVAC that provides targeted heating and cooling to individual rooms or zones in your home. Unlike central systems that push air through ducts, mini-splits use small, wall-mounted indoor units connected to an outdoor compressor.


Benefits of Mini-Split Systems


1. Zoned Comfort

Customize temperatures for different rooms or areas. No more fighting over the thermostat or wasting energy in unused spaces.


2. Energy Efficiency

Mini-splits avoid the energy losses associated with ductwork, making them more efficient than traditional systems. Many models are ENERGY STAR® certified.


3. Year-Round Climate Control

With both heating and cooling capabilities, mini-splits are perfect for Missouri and Illinois’ unpredictable weather patterns.


4. Easy Installation

No ductwork? No problem. Mini-splits are ideal for older homes, additions, basements, and garages.


5. Quiet Operation

Mini-splits are known for being whisper-quiet, making them a great option for bedrooms, nurseries, or home offices.
