Our El Sobrante house is on a slope and the Gree outdoor unit is far below the deck. Is that a problem?

Only if it is beyond the limits for your model. Each Gree line lists a maximum height difference and line length. We measure both and compare them with the install manual. If the system is outside the limits, we explain the options, from moving the outdoor unit to rerunning the line set.

Why does our Gree outdoor unit make a whooshing sound and then go quiet?

That is usually the reversing valve shifting at the start or end of a defrost cycle in heat mode, and it is normal. Grinding, rattling or a loud buzz is different and points to a fan, a loose panel or a failing compressor part. A short run test tells us which.

Should we repair or replace a Gree system that has already had one refrigerant leak?

One leak, found and fixed properly, is not a reason to replace. Repeated leaks at different points, or a leak in the coil itself, change the math. We show you the repair price next to a replacement quote in writing, and you choose.

Gree in El Sobrante

Gree heating and cooling in El Sobrante.

Homes in El Sobrante climb into the hills above San Pablo Dam Road, and most of the housing, from old ranchettes to later subdivisions, was built between 1940 and 1979. On a hillside lot, a Gree outdoor unit may sit a full story or more below the indoor head. Every Gree line has limits on that height difference and on total line length, and a system installed past them can struggle to return oil to the compressor.

So on a hillside call we measure the run and the rise as well as reading the codes. Our El Sobrante customers are served from Benicia, where our technician is based. The diagnostic is $99, credited toward the repair once you approve it, and you get a written quote first. ADRIUM holds EPA 608 Universal certification for refrigerant work, and our license is CSLB #1136642.

Common repairs we handle.

System losing capacity on a long, steep line set. Past the rated height or length, oil can pool in the lines and refrigerant can fall short at the head. Cooling fades and the compressor runs hot. We measure the run against the install limits, check for oil traps, recalculate the added charge and weigh it in.
Head in an older ranchette dripping from the front. Drain lines in older houses may run through a crawlspace or out an exterior wall with little fall. A sag or a clog backs water into the head. We clear the line, restore the slope and add a condensate pump only if the drain cannot fall by gravity.
Head shutting off with a freeze-protection code. If the indoor coil gets too cold, a sensor stops the compressor to protect it. Low airflow from a dirty wheel or a low charge usually causes it. We check the blower, the filters and the coil sensor, then read pressures to rule the charge in or out.
