Why Is My AC Running But Not Cooling The House?
An air conditioner can run without cooling when airflow is restricted, refrigerant is low, or the outdoor unit can’t reject heat. The most common cause is a clogged filter or coil that chokes airflow and drops cooling output fast. Electrical or control faults can also leave the fan running while the compressor cannot do the heavy work. A quick technician check: if the indoor blower and outdoor fan run but the larger…
What Does HVAC Repair Usually Include For Homeowners?
HVAC repair for homeowners usually includes a full system diagnostic, clear repair options with upfront next steps, and the parts replacement or adjustments needed to restore safe, efficient heating or cooling. Most calls start with issues tied to airflow, thermostat or electrical controls, or wear on motors and capacitors.

Why Is My Air Conditioner Not Turning On Despite Thermostat Set to Cool?
An air conditioner that won’t turn on with the thermostat set to Cool usually indicates a power, control, or safety lockout issue rather than a bad thermostat.

Why Is My Air Conditioner Running But Not Cooling Properly?
Your AC can run without cooling due to a clogged air filter, blocked outdoor unit, incorrect thermostat settings, low refrigerant, a frozen coil, or duct problems. If airflow feels weak or warm in Boise or Nampa, these are likely causes.
