and many more …

* Variable refrigerant flow (VRF) is an HVAC technology that uses refrigerant as the cooling and heating medium, similar to ductless minisplit air conditioning and heating systems. The refrigerant is conditioned by a single outdoor condensing unit and is circulated within a building to multiple fan-coil units for air distribution. This system saves energy and space as it does away with much of the need for duct-work in ceilings.

All The Right Things


Each zone can be individually controlled and the HVAC system can detect the precise temperature. Zoning capabilities provide the most comfort and well-controlled humidity and no hot or cold spots.


Systems should provide state-of-the-art efficiency and performance. Our recommended equipment are approved by the California Energy Commission and California Title 24 standards.


VRF  and mini-split HVAC systems may cost more than traditional central air systems up front. However, this cost can be offset by lower energy bills, less repair and maintenance expenses in the future.


HVAC is a global system, and you can rest easy knowing that the technology will be updating and improving it for years to come.
