Service 04
Mini splits and VRF, installed and serviced properly.
Ductless and VRF systems are efficient and quiet, and unforgiving of poor installation. Line sizing, charge and communication wiring have to be right. We install them carefully and repair the ones that were not.

Scope
Where these systems fit
Ductless is not only for homes. These are the jobs we install and service most.
Server and IT rooms
Dedicated cooling that runs all year, independent of the building system.
Offices with uneven comfort
Individual zones for conference rooms, corner offices and tenant spaces.
Additions and converted spaces
Rooms the existing ductwork was never sized to reach.
Buildings with no room for ducts
Older and historic buildings where ducting is not practical.
Multi-tenant and mixed use
VRF with separate zones and simultaneous heating and cooling.
Homes and ADUs
Quiet, efficient heating and cooling room by room.
Approach
What we do
We can assess whether it suits the space and install it correctly, or tell you honestly if it does not.
- Load and layout. Equipment sized to the room and placed where it will actually condition the space.
- Clean installation. Correct line sets, flare or brazed joints, nitrogen pressure test and deep vacuum.
- Condensate done right. Gravity drains where possible and reliable pumps where not.
- VRF diagnostics. Communication errors, refrigerant leaks, branch boxes and failed boards.
- Repairs on existing systems. Including systems installed by others that never worked correctly.
- Maintenance. Filters, coils, drains and checks that keep efficiency where it should be.

Questions
Ductless Mini Splits & VRF Systems: common questions
What is the difference between a mini split and VRF?
A mini split connects one outdoor unit to one or a few indoor units. VRF connects many indoor units to shared outdoor equipment and modulates refrigerant flow to each zone, which suits larger buildings.
Can you fix a VRF system another contractor installed?
Yes. We diagnose communication faults, leaks and commissioning errors on existing systems and correct them.
Is a mini split enough for a server room?
Often, yes, when it is sized for the heat load and set up for year-round cooling. For critical rooms we recommend redundancy, and we explain the options.
Do mini splits heat as well as cool?
Most are heat pumps and do both efficiently, which suits the Los Angeles climate well.
