Why Is the Fan on My Outdoor AC Unit Not Spinning?
Outdoor AC fan stopped while the unit hums? Usually a capacitor, fan motor or contactor. Why to shut it off now, what you can check safely, and typical costs.

New Hope homeowners pay a $79 trip charge for an AC service call, waived as soon as you approve the repair, and see the written flat-rate price first. We're open 7 days, 7am–9pm. In split-entries here, a frozen coil often starts with a starved return rather than low refrigerant.
When a New Hope air conditioner freezes up, look at the return before the refrigerant. Panned joist returns in these 1960s ramblers and split-entries are small and leaky, and a coil that doesn't get enough warm air across it drops below freezing and ices over. Water then pours out of the drain pan as it thaws. We check static pressure, blower speed and the filter along with the charge.
The upper level of a split-entry takes the afternoon sun while the thermostat sits near the stairs, so a warm upstairs is a common complaint even with a working system. Outside, condensers sit in narrow side yards between houses built close together, often beside a dryer vent or under a gutter that overflows. Lint and cottonwood blanket the coil by late June, and pressures climb. Capacitors, contactors and fan motors are the usual failed parts on units that have run 15 summers or more.

In a split-entry, cool air settles in the half-buried lower level, which already runs cool, while the upper level collects heat. One thermostat can't satisfy both. We first confirm the AC is working with temperature and charge readings. Then the fix is airflow: close lower-level dampers partway in summer and open them again in winter, and run the fan on low to mix the house.
Yes. A dryer blows warm, lint-heavy air, and a condenser pulls air in through its sides. Lint coats the fins fast, and the unit has to reject heat into air that's already warm. Redirecting the dryer vent or moving the vent hood is often cheaper than repeated coil cleanings. We clean the coil during the visit and point out whether the dryer is what fouled it.
