Found the filter soaked from thawing. I removed it and verified that the coil was not frozen. I checked the refrigerant pressures on the system and determined the system to be low on R410a. I spoke with the home owner to provide options to address the issue. I offered to charge it up, charge it up with leak sealer, and system replacement. Customer said they wanted to contact their home warranty and call us back. I stopped the diagnosis once they insisted on calling home warranty.

Performed a 1 system spring maintenance ( gas). Tasks performed. 1. Visually inspected condenser coil for debris/ dirty. 2. Inspected condenser fan motor. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested compressor/ condenser fan motor capacitor/ contactor,,,,,contactor is reading 11-12 ohms of resistance,, it’s right on the edge and needs to be replaced. 6. Checked refrigerant pressures. 7. Checked compressor amp draw. 8. Checked condenser fan motor amp draw. 9. Inspected / replaced return filter,,,it’s dirty, homeowner will replace it later. 10. Inspected return plenum for debris/ dirty. 11. Inspected evaporator coil. 12. Inspected blower motor/ blower wheel,,it’s slightly dusty . 13. Checked blower amp draw. 14. Measured temperature differential . 15. Inspected drain lines. 16. Washed condenser unit.

I arrived to one of the units not cooling properly and being frozen over. They had shut off power to the 4th unit outside and I found the indoor unit labeled 4. The corresponding thermostat was set to 73° but was reading 75°. Outside I turned the unit on and immediately could see it was reading low pressure. Subsequently the outdoor contactor had been burnt and failed on 1 leg and needed to be replaced due to high demand from the compressor. I shared my findings with Sharon and she authorized me to replace the failed contactor and add Freon only. Once the contactor was replaced I proceeded to add Freon by the pound. By the second point the unit pressures started to behave as if there was a restriction in the Freon lines. It is now after 5pm and I am unable to confirm if there is a TXV or a piston in the system. I and also unable to check all of the return filters for this particular unit. I spoke with Sharon with my further diagnostic’s and we agreed it would be best for me to ret

House numbers changed customer does not need estimate

Cleaned both air effects filters, both in good working order upon departure.

Performed a 1 system spring maintenance ( heat pump). Tasks performed. 1. Visually inspected condenser coil for debris/ dirty. 2. Inspected condenser fan motor. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested compressor/ condenser fan motor capacitor. 6. Checked refrigerant pressures. 7. Checked compressor amp draw. 8. Checked condenser fan motor amp draw. 9. Inspected / replaced return filter. 10. Inspected return plenum for debris/ dirty. 11. Inspected evaporator coil. 12. Inspected blower motor/ blower wheel. 13. Checked blower amp draw. 14. Measured temperature differential . 15. Inspected drain lines,,,emergency drain pan is rusted,,, recommended a pan treatment. 16. Washed condenser unit. Found no issues at this time.

Found contactor engaged when calling for cooling, but compressor and fan were not operating. Found dead bugs mashed inside contactor. Tested contactor and found inconsistent reading. Replaced contactor and unit began cooling normally.

Arrived at home for a duct cleaning estimate. Our clients are in the process of cleaning and painting and wanted the ducts cleaned before moving forward with projects. I inspected the blower motor and wheel and our client elected to clean that himself. We are scheduled to preform the service Friday afternoon at 1pm.

Customer stated it was warm on the master bedroom side of the house. I found the thermostat set to heat and a schedule set up on the other thermostat. I set both thermostats to maintain a range permanently to the customers preference. Both air handlers had dirty air effects filters and dirty blower wheels contributing to high amps on both units. 20° temp split measured on both units. Both outdoor units had high star amps. Both contactors and capacitors were testing with range. Washed both outdoor units to promote heat exchange and keep systems alive. Recommendations: Two blower wheel cleanings Two clean air effects filter cleanings

Started inspection on studio unit. Upon initial inspection, noticed that the filters were not a good fit. Recommended a customer using Honeywell filters as they will not allow as much dust past. I was starting to notice some accumulation of dust on the blower wheel likely due to the filter situation. Unit may need blower wheel cleaning in the future. Measured a 20° split between supply and return as expected. At the outdoor unit start and run amps for testing within range. wash condenser coils to promote heat exchange as they were pretty dirty. Everything operating normally. Proceeding to the main house unit, I changed the filter and tested the start and run amps on the blower motor. Amps were testing in range and I measured a 20° split from the supply and return as expected. Proceeding to condenser I tested the contactor and capacitor. Both were testing within range. I however did find this condenser start amps to be high which will put undue wear and tear on the unit. I would recomme
