The water heater was off on reset. Checked the fuel flow which is strong and clear. Checked the transformer which was very weak. The transformer needs to be replaced. Replaced the transformer. Started and burned off excess oil in chamber. Cycled and it’s operating properly.
Performed a heating pm on a Gas Furnace and Gas Hot Water Heater. Checked gas pressures and checked safeties. Blew out drain line. Checked electrical connections. Checked air filter (starting to get dirty, customer has replacements). Started and checked operation of furnace and dampers. Recommend replacing the neutralizer pellets in the condensate drain. Removed the burner assembly on the water heater and cleaned. Checked the safety and operation. Drained some water out of the tank. Recommend replacing the anode rods in the water heater every couple of years. Both systems are operating properly. Goodman GMES960603BNAA Sn 2002303370 Rheem PROG50-42N Sn 0142023280
Checked system. The thermostat was not getting any power. It’s hardwired. Found the low voltage fuse in the furnace was blown. Replaced fuse, had 24v at the thermostat. Checked wires. Found the sub base for the thermostat was bad. Replaced the sub base. The furnace turned on but the condenser did not. The thermostat wire at the condenser was cut which shorted out sub base and fuse. Repaired the wires and system turns on properly. Checked the charge. The system is properly charged and cooling off the space.
Upon arrival found that one zone was calling and had 28 volts at the zone valve allowing water through that zone and causing the boiler to run. Turned all zones off and tested each thermostat one by one to figure out which zone was calling. Determined that the zone that was calling was the bedroom in the secondary part of the house. All other thermostats and zones were turning on and off properly. Labeled all zone valves and wrote on a paper near the zone valves for the corresponding thermostats for future reference. Unit is operating properly.
Checked system. Boiler was at temp but customer did not have any hot water. Checked the indirect tank. The was hot water going into the tank from the tankless coil but the circulator pump was not running. Followed the power cord to a strip plug that did not have power. All the breakers were good. The outlet for the strip plug was tied to a GFI outlet on the other side of the wall that was tripped. Reset and pump is working properly. Noticed some water on the floor need the pressure relief valve. Drained some the pressure to 20 psi and it was slowly going up. Shut the valve for the water feed and the pressure stayed steady. Recommend replacing the automatic water feed when the PM is done and tie in the circ pump to the switch at the boiler.
Removed old control board from the furnace. Installed new control board and swapped all wires over to the correct spades on the new board. Tested the furnace in heating and cooling modes and in both the unit was functioning properly. Attached sticker notifying of the modifications as per the manufacturer.
Brushed and vacuumed flu pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Preformed combustion and smoke tests 6.1%o2 2ppm co 0 smoke
Checked system. The filter that was in the filter grill was removed due to being dirty. There was also a filter inside the air handler which also was dirty. Replaced the filter in the filter grill. 16x20x1. Checked pressures and temps. The system was low on Freon. Added 1 lb 3oz R-410a to the system. System is discharging 56*f. Checked the heating system. System is operating properly.
Removed and replaced four zone dampers and zone panel. Installed a discharge air sensor. Started and checked operation.
Customer mention that he pushed in on the fuse inside the furnace on the circuit board, and the system started back up. Checked furnace and circuit board. While moving wires, the blower shut off, then turn back on. When pushing on the circuitboard terminals, nothing happened. The screws for the wires or slightly loose. Tightened the screws. After tightening, moved the wires again and the “r” red wire broke next to the terminal screw. Striped wire and checked. With the wire almost ready to break, it can cause an intermittent condition. System is operating properly.
Customer turned system on and compressor tried to start. Checked capacitor and it was bad. Replaced the capacitor and tested. System is operating properly. 59*f discharge temp.
Customer turned system on, condenser turned on. Checked charge, system is low on refrigerant. Added 4lb 5 oz R-410a to system to achieve 10.8* subcooling. The unit is discharging 64*f and still dropping. The system is operating properly.
Upon arrival unit was off. Customer stated there was water coming from the furnace and water around the condenser. Cleared drain line and poured water down it to test it. Noticed the condenser coil had a high buildup of dirt and debris on it. After getting customer approval we chemically cleaned the condenser coil. Started and tested the unit. Had good pressures and temps. Subcooling was at 14 and the unit calls for 12 which is acceptable. Customer stated they had just recently replaced the air filter which could had contributed to the coil starting to ice up and produce more condensation. Unit is working properly.
Upon arrival unit was off. Found the secondary drain pan was full of water and had tripped the float switch. Used a shop vac to remove all of the water and reset the float switch. After getting customer approval we chemically cleaned the condenser coil due to a large buildup of dust and pollen effecting the pressures. After chemically cleaning we checked the refrigerant levels. System was at 35/150 with 44.5 degrees superheat. After getting customer approval we added 2 lbs R22 to the system. The system is now at 57/170 with 42.8 degrees superheat. Took pictures and measurements for a replacement quote. There is no guarantee on how long the refrigerant will last. Due to the system not being fully charged there may still be issues with the system operation.
Upon arrival customer showed us where the water was dripping from. The water was coming from a drain line from inside the house and was dripping onto the siding. Extended drain line closer to the ground so it won’t drip on the house any more.
Checked system. Found the air filter was plugged. Checked evaporator coil. Coil is clean. Replaced air filter. Rinsed condenser coil. Checked pressures and temps. System is operating properly.
Checked system, the furnace was blowing air and calling for cooling. Went outside and checked the condenser, which was not running. Checked for power. There was 0 V at the condenser and disconnect was on. Found the breaker in the panel was off. Switched breaker on and the condenser turned on. checked pressures and temperatures. 59° supply, 77° return. System had 9.2° sub cooling. The system is operating properly. Showed the customer where the breaker was and attached the zone panel cover to the panel. Also showed the customer pics of the cover being on in Dec 2022. The system is operating properly.
Performed an ac maintenance. Filled out the check list. Blew out the drain. No issues found. Customer has a washable filter. Filter was very clean. System is very old. Customer would like the invoice mailed. Customer paid with check on 5-18-23
Performed and ac maintenance. Two head mini split. Fujitsu. Cleaned the filters. Rinsed the condenser coil. Inspected electrical. Cleared the drains. Took temperature readings. Tested the refrigerant levels. No signs of leaks. I had good pressures and temperatures. Recommend having both heads chemically cleaned due to them having a build up of debris on the blower wheel. Included an estimate to have them cleaned.
Replaced the thermostat for the upstairs with a Pro One thermostat, non- programmable. Checked the operation. System is operating properly
Checked system, all three zones were calling for heat. The second floor is cold, tried purging the 2nd floor, there was no water coming out. Purged the other 2 zones with no issues. The 2nd fl zone is frozen due to the piping is in an overhang on the house. The pipes need to thaw out. The outdoor temp will be going back into the 40’s starting tomorrow. After the pipe thaws out, recommend adding glycol to the system, to help avoid this happening. The 2nd fl piping froze last year,January 31,2022 and glycol was also recommended at that time.
Found the thermostat batteries were dead. Replaced the batteries(customer supplied) and the unit started working properly. Found the condensate pump was running non stop. Blew out the line and tested. It still ran nonstop and was pumping really slow. Recommend replacing the pump. Included an estimate.
