Our AC installation crew arrived at a commercial property this afternoon to begin tear down of their air conditioning equipment. Once tear down was complete, crane arrived and removed existing unit and placed new equipment onto curb. Our technician connected all all components, sealing ducting and ran new drain line. System was tested in both heating and cooling. New A/C is operational and working well.
Emergency service requested at a chiropractor's office in Monrovia California. Site reported a copper pipe was leaking water and they believed it was from the AC. Upon arrival, our commercial HVAC technician found that the pipe was actually a pressurized 3/4" copper pipe that would need a plumber to repair. Confirmed that no leaks were coming from the air conditioner, updated manager on duty to call in their plumbing contractor.
Responded to a report from our customer's alarm company that one of their HVAC units had tripped their alarm. Upon arrival, found the #2 Lennox air conditioner with a tripped breaker due to a grounded compressor and bad contactor. Disconnected the circuit and tested circuits #2 and #3. Found a bad condenser fan motor on circuit #2, and the blower motor not coming on due to a faulty VFD. Requested VFD from provider, will source and quote the other parts ASAP. Confirmed remaining units are functional through EMS.
