Customer turned the system on and the air handler did not start. Chlorine power. The digital display was blank. The fuses were good and there was 24 volts. The digital display is bad. Removed the display from an unused ahu, the error was “ blower communication error”. There was 240 volts at the motor. Tried jumping out the power to the module, nothing happened. The lower motor is bad. Removed the blower assembly from an unused ahu and installed it in the bedroom air handler. Turned power on and the blower started properly. Need to replace the display module and the blower motor on the unused air handler.

During a spring service call, I noticed inconsistent airflow across zones. Did a full inspection of the duct system and found two sections of unsealed flex connections in the attic. Sealed all joints with mastic, reinforced with zip ties, and rechecked airflow with a manometer. The customer had been noticing hot spots—this should correct it.

Installed a new variable-speed heat pump today, replacing a 13 SEER unit that had multiple compressor lockouts. We upgraded the thermostat to a smart model and adjusted the duct transitions to better fit the new air handler. Final static pressure reading was slightly high, so I’ll recommend a return duct modification on the follow-up.

Upon arrival furnace was flashing 3 times indicating it was off on a limit switch code. Checked the limit switch and it was good. Checked the air filter and found it was plugged. With a plugged air filter the heat exchanger of the furnace could not fully cool down causing it to fail with the limit switch code. Replaced the air filter with a customer supplied air filter. Cycled power to the unit to clear the code and started the unit. Unit is now working properly

Disconnected and blew out the oil lines for both the water heater and the boiler. Installed a new coated oil line and a tiger loop. Connected the water heater and boiler to the tiger loop. Checked for leaks. Started and tested.

Burner was off on reset when arrived. Checked the oil flow, it was clean and strong. Turned the water heater on with the boiler running and there was no change in flow. Checked the nozzle assembly, there was a small dark spot on the tip of the nozzle, which indicates that the nozzle is not spraying correctly. Replaced the nozzle. Started and tested

Performed a heating pm on (2)gas furnaces. Cleaned the flame sensors, checked the gas pressures. Checked the heat exchangers. Blew out the condensate drains. Replaced the air filter with a customer supplied filter for the main house. The filter for the addition needs to be replaced. That is a 5” filter. Started and checked the safeties. Performed a combustion test. System is operating properly. Recommend replacing the neutralizer stones in the condensate pump for the addition furnace.
