On arrival checked thermostat operation, thermostat was calling for heat. We inspected both units in the attic, replace filters, inspected electrical connections, change a belt, and inspected heat exchanger. Units are operating normal.
Costumer had tubing freeze from condensate pump from dumping outside. Ran tubing to sink in basement to prevent any issue like that happening again . Also foam sealed hole that the lineset was ran through before . Costumer also mentioned sink hole above water lines , says it wasnâ€™t there until recently . He also said the drilling company hasnâ€™t came back out to fix landscaping due to rain . I told him to give them a call and tell them what is going on . Also told him I would put it in our notes . The equipment was off on an E3 for low pressure lockout . I called tech support and gave him my numbers . Incoming water pressure 35 and out is 32 . Incoming water temp was 44 and leaving was 39 . Supply air 97 and return air 70 . He told me to adjust water flow to system because it was at 14 gpm and had me take it down to 80 percent to have it at 11 gpm . System is operating
Replace weak capacitor. Upon arrival I went to system and shut off power. Removed old run capacitor and installed new one. Removed bracket to fit new cap then installed wires and mounted to panel. Returned power to system and ran heat. Checked parameters and found no additional problems. Foam tape was peeling around PT ports, used zip ties to secure. Also spoke to customer about Intellistart. Link below is brochure with more information for customer. https://www.dropbox.com/s/y8cwfh4hnsnj81e/Inteli%20Start.pdf?dl=0
Performed heating pm on 3 furnaces. Replaced all filters and belt (9) 20x22x1 and (1) A55. Inspected coils and blowers, all clean. Flushed out drain with brush and hot water. Found furnace 2 pilot out, relit and furnace operated normal. Recommend to replace thermocouple. Preparing quote. Ran all furnaces and checked operation. Measured amp draw of all blower motors. Checked gas pressures and heat rise. Inspected heat exchangers and cleaned burners. Because furnace 2 hadnâ€™t been running, there was a slight burning smell when firing up. Informed customer that it will go away shortly. Heat exchanger in good shape. All units operating normal at this time.
Performed pm on both geo systems. Washable filters are clean. Coils,and blowers are clean,. Flushed out drains with brush and hot water, tested condensate pump. Checked capacitors and contactors. Packaged system capacitor out of spec, customer declined replacing. Flushed out humidifier canisters and loaded with new water. Tested operation. Found top floor humidifier outlet gfi was tripped. Customer mentioned that it happens from time to time but believes the humidifier isnâ€™t the cause because it trips in the summer as well. Ran aux heat and measured amp draw and heat rise. Ran HeatPumps and measured amp draw of compressors, blowers, and loop pumps. Measured delta loop pressures and temps as well as delta air temps. Both units operating normal. Suggested customer get spare humidifier canister for future use since they wear out over time.
Completed heating maintenance. Found that the package unit capacitor is weak and needs to be replaced . Costumer approved estimate .
I replaced the units filters. I confirmed proper flow rate and loop pressures. I operated the units on auxiliary heat and second stage heating mode. I decreased blower speed in the split system to increase temperature rise to decrease units run time. Electrical wiring and electrical systems are within specification and both units are operating normal.
