Hvac repair — San Francisco, CA

The key components of a vehicle's AC system include the compressor, which pressurizes and circulates refrigerant; the condenser, which dissipates heat from the refrigerant; the expansion valve or orifice tube, which regulates refrigerant flow; and the evaporator, which absorbs heat from the cabin air. Additionally, a receiver-drier or accumulator removes moisture from the refrigerant. Technicians also inspect refrigerant lines, seals, and electrical connections to ensure the entire system functions cohesively for optimal cooling.

Signs that a furnace in San Francisco needs repair include a lack of heat, inconsistent heating, strange noises such as banging or squealing, or a pilot light that won't stay lit. You might also notice a decrease in airflow from your vents or an unusual smell, such as burning dust or gas.
