Construction warranty System is tripping limit switch. Adjust gas pressures to lowest allowed by sticker. Adjust blower speeds up, two for low stage and three for high stage, to bring the temperature rise down to the lower end of temperature rise range.
Upon arrival, system was operating in heating mode. Shortly after, system shut down on code 33 for limit circuit fault. Inspection of system shows that manifold gas pressure is at 3.7inwc. Blower speed is on medium and system has a clean filter. Upon initial test run of the unit, the system was operating with a very high temperature rise. This will cause shortcycling, and in turn, will also cause uneven heating of the house. Adjustments made are setting the gas pressure to 3.0inwc and increasing blower speed from medium to medium-high. This will also help with uneven heating of the house. With new adjustments, the system is operating within manufacturers specifications for temperature rise, gas pressure, and blower operation. No other issues are found or suspected at this time. Lower gas pressure will ensure longer run times. Increased blower speed will force more air to the second floor of the house. It is also recommended to turn the fan setting on the thermostat to "on." All three
Service warranty Upon arrival, thermostat is reading 48% humidity and standalone sensors are reading 15%. Used psycrometer to accurately measure humidity at 38%. Set offset on thermostat to read 38%. Inspection of humidifier shows wire plug on molex connecter has been disconnected, most likely during the maintenance. Plugged wire back in and test ran operation. All humidity settings and equipment are operating properly.
Construction warranty. Humidifier wired and programmed incorrectly at thermostat. Properly wire and program. Test operation.
Change humidifier water supply from cold to hot water. Shut off and drain hot water. Cut water line and install t-fitting and water valve. Turn on water and check for proper operation and leaks. System is setup with hot water now.
Performed heating maintenance on a 2021 Carrier 2 stage 96% efficient natural gas furnace Replaced 20x25x4 filter with the gold plan provided filter Replaced aprilaire 600 humidifier #35 water panel Washed humidifier tray Cleared hard water blockage from distributor tube Set water flow at the control valve above the water heater Tested operation: no water leaks, operating properly at this time Pulled flame sensor and cleaned Condensate trap is clear Burners in great shape, no rust Blower in good shape Set airflow for efficiency speeds Intake and exhaust pipes are in good shape, no signs of leaks High fire gas pressure set to 3.2"wc, Temperature rise 60⁰ Low fire gas pressure set to 1.3"wc, temperature rise 52⁰ No concerns found on today's visit
upon arrival inspected system and found blower motor would not operate. checked capacitor it was 7.9 replaced with fresh 10 blower started but angrily. informed homeowner blower should be replaced, quote was approved replaced motor and test ran system. no further concerns post repair unit is heating adequately
Common drain for humidifier and dehumidifier clogged again Put drain treatment in the dehumidifier drain, changed the humidifier water panel and put drain treatment on the top of the water distributor panel, also put drain treatment in the drainline itself Curious the water panel was so degraded in just over a month. Suspect water quality issues being a contributing factor.
Google Nest thermostat is not properly controlling the humidifier. Confirmed proper wiring and that humidifier shuts off when furnace is powered off. This eliminates the possibility of tne wiring, or humidifier solenoid valve being the issue. Thermostat is powering humidifier when humidity is satisfied. Humidity set point of 45% and thermostat is still powering humidifier when it is reading 48%. Thermostat will need replaced. Japinder will replace the thermostat himself. Westin Air recommends Fresh Air Corps for duct work cleaning.
Hookup aid tool and inspect system for faults, found 4 high pressure 999 hot water limit and 4 system resets. Reset faults and informed homeowner of high pressure likely being sourced from dirty filters from previous owners. Inspect refrigerant pressures and loop temps loop pressure low at 5psi pumped up to 40 psi with house water. No concerns at this time humidifier clean and on filter clean.

Preventative maintenence inspection on Carrier high efficiency furnace running in great condition. 20x25x4 air filter is new today. Humidifier pad in good condition and damper opened. Confirmed water is on. Humidifier is operating properly. On furnace, clean flame sensor and check ignitor. Visual inspection of burners. Flush condensation trap and drain lines. Run test unit in heating mode. Temperature rise is within specs. Blower and inducer motors tested good. Pvc flue vents in good condition and no sign of leaks. 0PPM CO detected during testing. Furnace is operating properly, efficiently and ready for Winter. Humidifier is operating properly. Humidity level issues are a combination of low outdoor temperature and being supplied with cold water. Due to lower cold water temperature, the Humidifier is not able to evaporate a sufficient amount compared to using hot water. System is supplied with cold water as water supply valve being used was installed by plumbers during construction. I
