Air Temeprature Differential between Supply and Return Temperatures was only about 10 Degrees. Turned Thermostat up and Tested the Electric Heat Kit to ensure it was turning on. Proceeded to the Rooftop to further diagnose. Measured Refrigerant Charge on Unit. Temperature pressures were below the recommended levels. Added refrigerant to System to increase the Pressures/Temperatures of the Refrigerant. (Refrigerant was supplied). Checked Air Temperature Splits which had increased to about 35 Degrees. The Temperature inside the Apartment had increased to 73 Degrees upon completion.

When I arrived found furnace not running hit reset and had slight grinding noise.Found that burner coupler was broken and burner fan blade was bent. Talked to homeowner about issue and told her it was not worth it to keep throwing parts into this furnace. Talked to Joe about a burner at the shop we can temporarily get furnace running with.Need to schedule tomorrow for repair. 1/18/2019 Replaced burner moter, Burner blower wheel ,and coupler( All slightly used parts) and started up furnace and found burner had lost its prime ,had to bleed out air to get furnace to fire .(this problem is due to no tiger loop as recommended) furnace is back up and operating at this time only concern is losing prime again.

Drain Down Boiler and install a new Expansion Tank and test Water Pressure on Boiler after refilling. If the Relief Valve continues to leak even after the Expansion Tank is replaced and the Water Pressure reduced to the Proper Level the Relief Valve will need to be replaced as well. If the Pressure Relief Valve seats itself and does not leak after the Water Pressure is corrected it will not need to be replaced. 1-3-19 installed new relief valve and new expansion tank, set pressure equal to expansion tank to 12 psi test and cyclpump boiler ok check for leaks ok no leaks found, informed customer about valves all corroded and might have a problem in the future....

Performed Precision Heating Tune Up on Bryant Heat Pump System. Replaced 16x20x4 Air Filter provided by the Homeowner. Filter was very dirty and should be checked every 30 Days and replaced as needed. Performed Humidifier Servicing and cleaning. Humidity level is set to 40% at the Thermostat. While testing the Outdoor Unit, found that several wires from the Contactor and to the Compressor and Control Board had rubbed together and worn the Wiring Insulation away. This exposed the internal wiring and caused the Wires to begin melting. Made necessry repairs to the damaged wires and tested operation of the Heat Pump. Also found that the Air Scrubber Cell was not working. Recommend replacement of the Air Scrubber Cell.Thank You for renewing your Service Membership with us today!

Performed Precision Heating Tune Up on Ruud Heat Pump System. Checked High Efficiency 413 Air Filter. Filter was changed recently by Homeowner and was still in good condition. Performed Humdifier Service and tested operation of Humidifier upon Completion. Humidistat Control is set to 35%. Inspected Electrical Components on the Air Handler and Heat Pump. The Start Capacitor on the Heat Pump is testing within rating but is starting to corrode along the Top seals. This can indicate that the Capacitor is starting wear and will eventually fail. Recommend replacement of the Start Capacitor. As a Safety Enhancement, would recommend installing an ECM Motor Surge Protector for the Blower Motor. This can help prevent damage to the Motor in the Event of a Power Surge/Spike. Measured Refrigerant Charge in Heating Mode and tested Auxilary Electric Heat Kit.Thank You for renewing your Service Membership today!

Fan would not turn off, check wiring at stat and air hundler all those wires ok, found y and r shorted going to outdoor unit, noticed Line set on attic the parts that ar exposed, with thermostat wire splices, one line set has two with about 5 feet apart, so who knows how many splices can be between rooftop and first floor air hundler, there is not enough wires to interchange to get heat pump running, isolated outdoor wires and just connected thermostat wire to air hundler, so electric heat works, need further investigation if possible with trying to find a solution maintenance guy not available to sign work could not get signature.
