Chesterbrook, PA

Check up on a heat pump system. Checked the air filter and replaced. Checked the wiring connections and the voltages. Checked the thermostat in all heating modes, started with electric heat. Inspected the amps for the heating elements and checked the blower amps and the operation. Took electric heat temps at the return and supply. Performed a outdoor BTU output for the heat pump. Checked the outdoor unit, wire connections and the voltages. Inspected the components and tested the amps draws for the compressor and the fan motor. The heat pump is in good working order.

Arrived to the customer’s home to run a new 25’ line of 6” flex R8 insulation. I removed the wet 6” run out when she flooded her kitchen and discarded. I replaced it with the new insulated flex run . Made sure the flex is secured. The new 6” insulation is completed, Customer paid the balance .

Arrived to look at the customer’s duct work she had a water leak in her kitchen that flooded and got into the run out . She will need new r8 6” flex 25’ box quoted 279.17 she is scheduled for Monday .

Arrived at call for no heat on Goodman heat pump, took main door off unit to expose electrical panel saw that control board for indoor unit was not lit up, tested voltage across the main breaker coming into unit and had no voltage, went to electrical panel and tested voltage out of breaker one leg had power one leg did not push breaker in, but it did not make a difference, showed customer and gave him options on breaker replacement. Replaced breaker and tested unit no other issues at this time.

During initial start up found outdoor unit locked out on 3 red flash or 10 consecutive lockouts. What I ultimately found was that only every so often would the indoor blower motor energize when I had a demand for fan (I trace 24V to the speed tap 4 on the motor harness and common). I turned power off and then checked my blower motor surge protector connections and reconnected afterwards blower motor would energize every time. Recommend replacing the blower motor surge protector to be sure this doesn’t happen again. The surge protector was not passing the high voltage to the blower motor consistently. Homeowner agreed to replace X13 surge protector. Completed work today. Replaced Aprilaire 413 filter provided by homeowner Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components. Noticed that aux heat max temperature was 70° discussed and recommended setting to 40°F. 15KW electric heat 60A Good Measured temperature rise and static pressure

Arrived at call for water coming out of duct, found wood around boot was soaked so I went upstairs and checked all around register and realized the water was coming from the ice maker line out of the back of the fridge and went down stairs to turn off the saddle valve going to the line. Customer signed up for membership, equipment was added to system.

Expansion Tank Replacement ST-12, arrived call for replacement of tank. Drained electrical water heater after turning breaker off, removed old tank and installed new tank in its place. Water heater was refilled and hot water heater breaker turned back on and tested. No other issues with water heater.

Completed repairs to humidifier: new feed tube, ferrule, nut, inlet screen. Tested operations of humidifier. Set saddle valve for proper water flow to inlet of solenoid. Humidifier is controlled by a humidistat located just above humidifier. Targetbis 35% RH. Bypass damper is open. Completed tune up for 80,000 BTU natural gas furnace. 20x25x6 filter in good condition Inspected burners, heat exchanger, inducer assembly Cleaned flame sensor, verified flame rectification circuit Ignitor in good condition, measured correct ohms. Confirmed first stage and second stage manifold gas pressures Checked drains, tested pump; added treatment tabs to pump. Measured temperature rise and static pressure Combustion and draft tests: Pass System operating well at this time.

Mrs. Mcnichol explained that there was a small amount of water on floor near water heater. Expansion tank has failed. Water pressure when measured at tank is 110 psi. The ideal water pressure is between 50-65 psi. I attempted to adjust spring on pressure reducing valve but this had no effect. New expansion tank and domestic water pressure reducing able are needed. The relief valve may occasionally open until work is completed. I left estimates for domestic water pressure reducing valve and for domestic water expansion tank. She will call soon regarding estimates. Collected payment for diagnostic fee today.

Upon arrival for heat maintenance on heat pump tune up I changed the filter. Checked electrical and wiring and emergency heat kit. Checked blower motor and assembly. Checked delta t. Inspected coils. Checked fan motor and assembly. Checked refrigerant pressures. Forced unit into defrost. Unit seems slightly low on suction side. Looked at heating chart and it’s not too far off specs. Think this is because of the way the outdoor is close to objects on three sides making it have a slight airflow restriction. Unit is in normal operation at this time.
