What is your travel time to Millbrae from San Ramon for a dead mini-split?

Roughly an hour via 92 and 101, and often faster to schedule than you expect because Hillsborough next door is on our standing Peninsula rotation. A no-cool ADU with a tenant in it gets bumped up the list, and we run 7 days.

The installer who put in my Gree is gone. Can you take over service on it?

Yes, that is half our Gree work. We are a listed Gree contractor, I pull the model and serial, check the install against spec, and give you a written record of the system's actual state. Most orphaned Gree systems need one corrective visit and then behave for years.

My Gree shows a code for a few minutes and then runs again. Should I bother?

Yes. Intermittent codes are the system protecting itself, usually from a marginal board connection, low charge, or a fan issue, and they always escalate. Note the code and call us. The stored fault history on the outdoor board tells me how often it is really happening.

Gree in Millbrae

Gree heating and cooling in Millbrae.

Gree is the largest residential air-conditioner manufacturer in the world, and most people who own one have no idea. In Millbrae, Gree heads and multi-zone systems went into ADU conversions behind the mid-century houses, garage offices, and a fair number of the smaller apartment buildings within walking distance of BART, because the price per zone beat the Japanese brands and the hardware is legitimate.

The catch with Gree is not quality, it is workmanship at install and guesswork at repair. These are inverter systems with real diagnostics: the display and board LEDs report specific fault codes like E6 communication errors and H-series compressor protections. We are a listed Gree contractor, I service them from the code and the service data, and I am EPA Section 608 Universal certified for the refrigerant side.

Diagnostic is $75, waived with repair, written quote before parts, 1 year warranty on repairs. On new Gree installs we back the work with 10 year parts and 10 year labor.

Common repairs we do

What we close on the truck.

E6 communication errors between head and condenser. The most common Gree fault we see in Millbrae. The indoor unit throws E6 and stops. Sometimes it is a genuine outdoor board failure, but often it is signal wire spliced with wire nuts outside or run alongside line voltage at install. I test the communication line first, because the cheap fix is real and frequent.
Undercharge and flare leaks on ADU installs. Fast, low-bid ADU installs leave loose or badly cut flares, and two summers later the zone barely cools. I find the leak with electronic detection, remake the flare, evacuate to a verified vacuum, and weigh in the factory charge. Section 608 rules apply and we follow them.
Inverter and fan motor board protections. When a Gree condenser starts, ramps, and trips repeatedly, the codes distinguish compressor overcurrent from a failed outdoor fan motor letting head pressure climb. I read the stored fault history instead of swapping the compressor first, which is where guess-based repair burns owners on this brand.
