Ductless Systems in Walnut Creek, CA
Walnut Creek Ductless Systems

It’s amazing the ways you can cool your home conveniently with mini-split air conditioning in Walnut Creek, CA. Mini-splits deliver cool air from a discreet “head” installed in each room to fit your design needs, and a cooling line is connected through the outside wall. No ductwork is needed, and the system is both effective and quite efficient. Our Environmental Heating & Air Solutions professional HVAC design team can create a system using mini-split components to suit whatever room and building type you have. Ductless air conditioning offers solid, permanently installed cooling in Walnut Creek.
Expert Mini-Split Air Conditioning in Walnut Creek

Mini-split technology is an excellent solution for buildings that need cooling, but don’t already have ductwork in place. Older central air systems with aging single-zone ductwork can even be replaced with ductless room-based cooling as an efficient, easily installed alternative. The system is similar to central air, starting with a compressor unit located outside. Instead of pushing cool air through ductwork, mini split air conditioning delivers cooling lines to each room through the outside wall. Thermostat controlled distribution heads in each room cool the room’s air and circulate it locally. For larger rooms, a second head unit can be used for even cooling. Distribution heads are available in ceiling, wall, floor, and invisible mounting options. Multiple ductless cooling systems can be used for larger buildings, each typically providing cooling for up to four rooms. They’re a great solution for additions, home offices, garages, workshops, even pool houses. For a flexible, professionally-installed AC solution, mini splits can’t be beat!
Mini split air conditioning meets challenges like:
- Historic homes and other ductwork-free zones
- Add-on cooling for add-on spaces and outbuildings
- Replacement for older central air without zoned ducting
- Quick, straightforward cooling installation
