Summer heat (mid-to-upper 90s, heat waves to 105-110°F+)
High Desert summers run average highs in the mid-to-upper 90s, with multi-day heat waves that push 105-110°F-plus several times each July and August. Those extreme stretches are when capacitors fail, because a sun-baked condenser can exceed the part's internal heat rating. We carry 25 of the most common capacitor sizes on every truck.
