First no cool heat pump
Story:
Sent back out to a no cool call on a 5 year old rheem heat pump. First time out there system didn’t trip like customer said, not in cooling or heating. They called in and I was sent out today. Thankfully it was tripping but on low pressure this time. But my suction was 111 so I was confused. Error code “low pressure Lockout”. System tripped 3 times before running for 20+ minutes on the 4th cycle. Quoted a new low pressure sensor and system tripped another code (low pressure switch open). Long story short I consider this a win for my first no cool heat pump call. Ran the system 3 times for 10-15 minute intervals
Homeowner reset the breaker 4-5 times before my first visit. Assuming doing that he made the low pressure faulty. But any techs have an idea for its true fail point?
Personal note: been back in the field after a 3 year gap from 2023 to February 2026. As far as knowledge wise, I’m still learning and honing down on my efficiency
