I arrived to the customers home. He said the furnace wasn’t running at all. He did call before about a noise from His furnace and he said it will come and go. Looking at his furnace in the basement there were no lights on the control board. bottom door of the furnace wasn’t engaged completely I did reset the system and tested system operation. I checked combustion temp splits and monitored the flame. I did tell the customer that he is probably hearing his modulating inducer motor ramping up and down depending on ratio customer did sign up for a $189.00 contract and collected for diagnostic for $84.15 paid by check . Please schedule customer for his first call in the spring for a/c .
On arrival, customer had said the heat is struggling to keep up. We had put in an air handler and heat pump in August 2025 her actual issue wasn’t the air handler or the heat pump. Her boiler was locked out on flame lockout customer had mentioned she was getting low on propane and they were going to come at some point, I had About 9 inches water column coming in and at the igniter, I found a pinched wire that I took care of. I reset the system , and the system did fire back up and at the time that it fired back up, the propane company showed up the fill her tank. I checked the air handler and the coil was getting hot now her upstairs is getting warm again. I collected for diagnostic fees for tonight. She is back up and running at this time of service.

Luis 1-28-26 tenant called in because the heat pump is still not keeping up maximum temperature get it’s about 66° in the house. I went over heat pump, thermostat settings and I was able to see that the thermostat was not energizing auxiliary heat outside Temperature is 19° thermostat is set to lockout electric heat at 40°F. At 19° outside supply temperature it’s 88° and 66 coming back without auxiliary heat. I modify thermostat settings to bring auxiliary heat after 20 minutes of running time if thermostat not satisfied. I told tenant to keep an eye on the thermostat and if he still has issues to call us back. we might have to switch to a different thermostat.
Fully assessed defrost situation. Found thermostat set to 70 degrees when we arrived and calling for heat. Found system was completely defrosted at this time. Looked over install manual for defrost settings. Only two settings could be changed one was to reduce heating run time by 10% turned this dip switch on. Also turned on dip switch to extend defrost by 60 seconds, these are the only settings that can be adjusted. Also checked over all settings in the thermostat from install they were correct. Checked 454b refrigarant pressures on digital read out they were 272/55 very good let homeowner know the changes that were made. No charge due to recent install. Heat pump is working properly at time of service.
Found auxiliary pan full of water and float switch tripped. Causing loss of power to thermostat. The “rain gutter” tube was detached at the inducer exhaust elbow. I reattached. Removed water from pan (12 gallons) And then tested for any other sources of water. Replaced 16x25x1 filter Combustion and draft tests: Pass Told homeowner to set FAN to “On” at thermostat for a couple days to thoroughly dry the blower compartment. Left estimate for wet switch/flood safety. More effective and reliable water safety. Left estimate for EZ trap for AC drain line, has overfill protection switch, Also recommend and provided estimate for running condensate vinyl discharge to the available standpipe at water softening system drain. See photos. System operating well at this time.
