AC refrigerant leak — San Francisco, California
An AC refrigerant leak means your system is losing the chemical that absorbs heat, causing it to blow warm air, run constantly, and drive up energy bills. Refrigerant doesn't get 'used up' — if levels are low, there's a leak. Only an EPA-certified HVAC technician can legally locate, repair, and recharge the system.
Why this is common in San Francisco
The cool, foggy maritime climate means central AC is rare and rarely needed, so HVAC work centers on heating efficiency, ventilation, and increasingly heat-pump retrofits driven by Title 24 energy rules. Older homes often have undersized or outdated heating systems requiring careful upgrades.
