      Curious how everyone sequences a no-cool call to be efficient without skipping anything. Here’s mine right now:

      1. Talk to customer 30 sec — when did it start, anything unusual
      2. Check thermostat (battery, setting, calling for cool)
      3. Check filter
      4. Outdoor unit — listen first, then look (contactor, capacitor, fan motor, compressor amps)
      5. If outdoor running, indoor — coil, blower, drain
      6. Pressures last

      Trying to figure out where I’m losing time. What does yours look like?
