Returned to site due to Boiler not running. Spoke with technical support about issues. Removed and disassembled Burner. Installed a new Burner Assembly and went through manufacturer specs to adjust position of Flame Rod and the complete assembly. Cleared all tubing lines to ensure there were no obstructions. Reassembled Burner Assembly. Measured Gas Pressure for Pilot and main burner, and adjusted to manufacturer specifications. Adjusted Airflow Damper and performed Combustion Analysis on Boiler. Measured Readings on the Flame Signal to verify that it was detecting the flame correctly. Cycled Boiler multiple times and adjusted Air Damper. Adjusted settings on several controls in the control Panel for the system.

Replace indoor thermal expansion valve due to malfunctioning, could not pump down system, due to high side restriction, recovered all refrigerant and installed new valve, after installing new valve, pressure test system at 300 psi no leaks were found, performed triple evacuation, took long time to achieve 500 microns, added factory charge 8 lbs and 8 oz, check heat pump operation on heat and cool mode, the unit runs good on cool mode, does not pump down, check defrost operation could not get unit to go into defrost had to do it manually and checked out ok

Found that after homeowner gave call for heat humidifier came right on. There was water draining in the condensation pump. Humidistat was set on 45% humidity. Explained to homeowner on warmer days like yesterday , if the heat pump is not giving to many calls for heat to come on , your humidifier will not be running. Then also customer mentioned an oil smell like heating oil , found nothing inside air handler and also examined air scrubber, found nothing burned . Do not smell anything at unit that smells like heating oil.

Performed Quality Assurance on recently installed Amana Gas Furnace/AC system. Reviewed installation with homeowner. Completed checklist form in system. Recorded PECO Account number so we can process the rebates. Informed homeowners that they need to sign the E-Doc Signature. Need to bring 2-3 bags of stone when we return for Six-Month AC Inspection to fill in ground by the wall of the home where we dug up.

Reset unit controller and inspected pilot and main flames. Pilot flame was off and on spirratically. Spark was good. Checked pilot air tube and pilot regulator position. Marked air damper and adjusted and resinpected pilot flame. Flame was more stable after adjustment indicating there is too much air blowing pilot out. Performed combustion test on unit. Checked motor rotation to ensure it was correct. Adjusted air to decrease, decreased gas pressure at regulator, set combustion at 4% O2. Cycled to test operation. Raised mixed water temp from 120 to 140 to speed up heating building.

Service call that there was water leaking from the bottom of the Furnace. Upon arrival spoke with homeowner about issue. Was informed that the Condensation Pump was running nonstop earlier this morning when they noticed the leak. Found Discharge Tubing ran to an outside termination. With the Low Outdoor Temperatures this would have caused the Tubing to freeze and cause the pump to overflow. Rerouted the Vinyl Tubing to an inside Drain Pipe. Sealed old Section of Vinyl Tubing that was remaining inside and at the Outdoor Termination. Wired Condensation Pump safety switch into Control Board. If the Pump fails to pump out it will fill and trip the Float Switch and cut power to the system. Put unit back in operation. Filled pump multiple times to ensure it was pumping properly.
