Public listingAbout yumin wang
Furnaces, air conditioning and ventilation make up the listing for yumin wang, based in Fremont. Its profile puts the business at 2 years old. Team size: one.
The listing includes AC repair. Low refrigerant usually means there is a leak somewhere, so it is fair to ask whether a repair will find and fix the leak or only recharge the system. On A/C services needed, it says repair and routine maintenance. Listed property type: house, condo/apartment, townhouse and business.
Before calling, check that the thermostat is set to cool, the filter is not clogged and the breaker for the outdoor unit has not tripped, since those simple causes are common.
Posted hours are Monday to Saturday 1:00 pm to 6:00 pm, including Saturday. Towns near Fremont, like Newark, Alviso and Milpitas, may or may not be covered.
To get a useful answer from yumin wang, send photos of the labels on the indoor and outdoor units showing the brand, model and manufacture date. Ask each contractor to list the exact equipment model numbers so quotes can be compared on the same terms.
