Our postwar Pinole house has an old electrical panel. Can that cause problems for a Gree mini-split?

It can. A loose breaker, an undersized circuit or corroded terminals cause voltage dips that trip the inverter or damage a board. We measure voltage at the outdoor unit under load. If the panel side needs an electrician, we tell you before any HVAC parts are replaced.

Should every room in a Pinole Valley house get its own Gree head?

Not always. Bedrooms that close their doors at night do well with their own heads, while open living and dining areas can often share one. We look at the layout and the loads and suggest the fewest heads that keep every room comfortable.

Our Gree system came with the house and there is no paperwork. Can you still service it?

Yes. The model and serial numbers on the indoor and outdoor labels tell us which line it is and which parts fit. If the unit is still under the manufacturer's warranty, the serial number is where that claim starts.

Gree in Pinole

Gree heating and cooling in Pinole.

Much of Pinole was built in the postwar boom of the 1940s through the 1960s, when houses were wired for far less than they carry today. A Gree mini-split added to one of those homes should have its own circuit, and the condition of that circuit, the disconnect and the wiring to each head matters as much as the equipment. A loose connection can look exactly like a failed board.

In Pinole Valley, where homes run three bedrooms and up, a Multi+ system with several heads can cover the house from one outdoor unit. Pinole is served by our technician based in Benicia. We charge $99 to diagnose, credited toward the repair, and quote in writing before any work starts. CSLB #1136642.

Common repairs we handle.

Communication error between head and outdoor unit. When the indoor and outdoor boards stop talking, the head flashes a code and nothing runs. The cause is often a loose terminal, a nicked wire in the line-set bundle or a failing board. We check voltage at the disconnect, the signal on the communication wire and the connections at both ends before any board is ordered.
Sapphire or Livo head blowing weak air. The cross-flow blower wheel collects a paste of dust and lint, and airflow drops even with clean filters. The coil may freeze in cooling mode. We remove and wash the wheel, clean the coil and check that the fan motor reaches its rated speed.
Outdoor fan grinding or not turning. A worn fan motor bearing grinds, then stalls, and the inverter shuts the compressor down to protect it. We spin the fan by hand with the power off, check the motor and its connector, and replace the motor if it drags or overheats.
