My AC is running but not blowing cold air in San Antonio — what is wrong?
The usual suspects are a clogged filter, a frozen evaporator coil, a failed capacitor, low refrigerant from a leak, or a dirty outdoor condenser coil. Set the system to fan-only for a few hours to thaw ice and replace the filter, then get a professional diagnostic before the compressor is damaged.
My furnace is not working and there is no heat — can you help today?
