Upon my arrival the unit was running in cooling mode. I had 75 return and 60 supply, which is only 15 td. I went to the outdoor unit and applied my refrigerant gauges and had low suction and low discharge pressure with both high superheat and subcooling. I isolated the sensing bulb and in the process of doing that noticed a large puddle of water in the bottom of the duct under the coil. Heating and cooling the bulb resulted in little to no change of suction pressure and as the unit runs the subcooling gets higher and higher. The unit need to have the txv valve replaced. Customer approved this repair and paid $600. I completed a parts order form for the parts needed. I told the customer the office will call to schedule return visit to fix the system. The unit is operating some so customer does have some cooling in the meantime.

Hot water heater flue pipe was not secured properly and fell off the tank. I mounted it securely and sealed up any cracks or screw holes with aluminum flue tape. I took before and after pictures for warranty reasons.

Upon arrival I spoke with customer and him and he didn’t have a problem with furnace, only wanted to get system inspected. He and Donna spoke and it was agreed that for $99 I would inspect his furnace. Capacitor in spec, flame sensor a little dirty but correct spec, ignitor in spec. Inspected heat exchanger, good. Blower clean. Filter has decent amount of dust, customer may want to consider duct cleaning. Ran furnace and found normal heat rise and amp draw. System operating normal.

GEOTHERMAL WATER FURNACE FALL PREVENTATIVE MAINTENANCE SEVERN MD
Christopher A.
The compressor voltage absorption system (run capacitor) was rated for 30 and had a value of 8.36. Therefore the compressor could not start or run. Customer had turned the heat off last night, otherwise the auxiliary heat would have kicked on. I made sure the auxiliary heat strips did operate. I replaced the part with a 30uf single run capacitor with a start value of 30.35. I cycled the unit to make sure it would operate and checked the temperature rise: 25.4 degrees in second stage heat mode, which is within comfort range and units specifications. Unit operating normal. I retained the depleted capacitor to return to Water Furnace. I also spoke with the customer about the Intellistart modules.
