AC repair in Golden Valley starts with a $79 trip charge, waived once you approve the repair, and the price is written before any work. On wooded lots the cause is often a condenser choked with leaves and seed fluff.
Golden Valley's big wooded lots are pleasant in July and hard on condensers. Leaves, seed pods and cottonwood fluff pack into the fins, and pollen and sap help them stick, so the coil can't shed heat and the compressor runs hot. A unit tucked under a canopy or boxed in by shrubs also recirculates its own exhaust. Cleaning the coil and opening up clearance resolves many weak-cooling complaints on these lots.
Inside, most of the city's 1940s–60s ramblers and split-levels have add-on central air: a coil on a furnace fed by returns sized for heat. A loaded filter or a closed return is enough to freeze that coil on a humid afternoon. Additions at the far end of the ductwork run warm in summer for the same reason they run cold in winter, too little supply and no return. We measure charge and airflow before recommending any part.

Not necessarily. Large west glass takes in a lot of heat from mid-afternoon on, and a correctly sized system can trail the setpoint for a few hours on the hottest days. If it can't get close on an ordinary summer afternoon, or the air from the registers isn't much cooler than the room, something's wrong: low charge, a dirty coil or weak airflow. We measure before guessing, and shades or window film help either way.
The blinking light is a fault code, so note the pattern before you call. Common causes are a sensor fault, a communication error between the indoor and outdoor units, a clogged filter that lets the coil freeze, or a condensate problem. Turn the system off at its breaker for a minute to reset it once. If the code returns, leave it off and call; we read the code against the manufacturer's chart and test from there.
