Mini Split AC Systems in Fredericksburg and Fairfax, VA and NOVA

Efficient, Flexible Comfort with Mini Split AC Systems

When central air isn’t an option—or simply not efficient for your space—a mini split AC system offers the perfect solution. At OHA HVAC, Plumbing, Chimney and Fireplaces, we install and service mini split AC systems in Fredericksburg and Fairfax, VA, NOVA and surrounding areas. These ductless systems deliver targeted cooling and heating for individual rooms or zones, making them ideal for both residential and commercial spaces including additions, converted garages, home offices, or older homes without existing ductwork. With quiet operation, high energy efficiency, and sleek wall-mounted indoor units, mini splits give you total control over your comfort.

Why Choose a Mini Split System?

Mini split AC systems consist of one or more indoor air-handling units connected to an outdoor compressor. Each zone operates independently, allowing you to cool (or heat) only the rooms you use—saving energy and money. Installation is less invasive than traditional systems, with no need for bulky ductwork, and the setup can be customized to your building’s layout and usage needs.
