Uploaded a lot of compromised heat exchangers on all 8 gas unit heaters
DCM8: Heat complete. Upon arrival David Lester said they recently expanded and wanted us to check the two units in that building as well as the original 6. All 8 systems have compromised heat exchangers, meaning there is a greater risk for carbon monoxide to get into the building and/or cause systems to shut off due to cracks in the heat exchangers. Original 6 systems are approximately 26 years old and 2 systems in new building are 25 years old. Put compromised heat exchanger stickers on all units and informed David of issue. Left systems 1-7 running due to water pipes, sprinkler heads and product all being in the conditioned space. If we turn off units the water pipes could potentially freeze, cracking and then spilling water into warehouse. Set all thermostats to 50*. System 8 is not functioning the igniter control board has failed and system will not heat without igniter. Heat exchanger is compromised. Turned gas off to unit. Comfort advisor will need to give a quote for replacing
Replaced warranty defrost board and sensor, checked system, operating properly.
Performed single system Heat maintenance on, operating properly at this time
The coil sensor ohmed at 15000, which is 59 degrees so it is bad and needs replaced. The defrost board will not let the heat pump go into defrost it also is bad and needs replaced. I did Heat maintenance on air handler, upstairs unit, rheem. I cannot complete maintenance on outside unit due to unit frozen, cannot check pressures at this time. The parts is under warranty, labor. Office will confirm. Please order parts listed above.
Quoted in hvacbizpro and emailed over. Call after 4 to confirm if approved via GoodLeap financing - if declined then will need Microf for leasing
Primary drain line clogged - water in aux drain pan in attic Vacuumed water from pan, flushed drain line from attic out clogged - vacuumed line outside still clogged - worked drain line from inside to outside using nitrogen to free up clog - vacuumed lines and flushed with cleaner and water - tested with a gallon of water - drain line is now unclogged and free from debris at this time - primed drain line trap for proper drainage - some water may still be present in the drain pan and will evaporate over time - cannot remove every bit of the water
