Performed cooling maintenance, checked media air filter. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioner, checked refrigerant charge and temperature drop across coil.

No ac heat pump not coming on, check operation of heat pump, indoor unit runs, but no compressor, found open cap for fan side and open winding on compressor, installed new cap and test operation compressor would not come on, installed super boost and compressor came on, quoted for repairs customer ok repairs, recommend having system replaced

Checked condensate leak, checked condensate trap, looks clear, blew out condensate trap. Checked temperature drop, getting only 15 degrees, will need to change refrigerant charge. Due to storm we need to return to further diagnose Returned to continue to diagnose, checked refrigerant charge, found low on charge. Topped off refrigerant charge, balanced by superheat. Checked operation and temperature drop across coil. Recommend replacing vs repairs due to age and r22 refrigerant.

Found that duct work at air handler on the the return side is not very good for air flow. Found entire coil sweating except upper left hand side where the air flow does not transfer across very well. Found r410a refrigerant pressures to be 329/148 at 89 degrees. Pressures are pre well on. Only found 14 degree split at indoor unit, but system was keeping 72 degrees inside. He did have refrigerant added within a few weeks ago though explained to him that if the leak is is in the evaporator coil, it could be a $3,000 to $4,000 repair. Recommend he replace the system. He is going to wait at this point until the system stops cooling again.

Customer stated ac unit sometimes does not work, check ac operation heat pump with air handler 10 kw back up, down flow position, fitler ok, check temp split only 10 degrees, airflow is set to 800 2 ton heat pump check outdoor unit refrigerant pressures noticed capacitor reading 20 rated at 40, noticed return air is only hitting indoor coil by 50% other 50% is n,Ickes by sheet metal, coils needs a return transition so air passes at 100 % through coil, informed customer about findings system is running customer ok with repairs,,,system running at 72 return 62 supply

Service call that the AC was not cooling. Upon arrival spoke with homeowner about issue. System was turned off upon arrival. Inspected indoor coil and found small amounts of ice remaining on coil. Removed ice and put system in operation. Replaced 201 Air Filter provided by the homeowner. Checked Air Measurements and found only a 14 Degree Supply versus return differential. Measured refrigerant charge and found system low on charge. Added 3lbs of 410-A refrigerant to system, charging by Subcooling. Subcooling increased from 1 degree to 10 degrees and temperature split increased to 18 degrees. No dye was added to the system at this time. Would recommend a full AC Tune Maintenance on system.

Disconnect and remove existing ECM Blower Motor and housing. Install a new OEM Blower Motor Assembly and remount. Wire motor into system. Install new Control Board for Air Handler and wire into system. Set Dipswitch settings on Control Board. Put system in operation and test. Measure Temperature Rise across the Coil.

Service call that the system was not cooling the home. Upon arrival found indoor temperature at 85 Degrees and the system was set to cooling. Proceeded to the basement to trouble the system. Found indoor Coil and Lineset completely frozen and the blower motor not running. Control board was flashing a 6 Flash Red Light error code indicating an issue with the Blower motor operation. After testing, found blower motor was receiving 244 Volts for the high voltage but was not testing any 24V signal. Blower was attempting to start but would slowly spin a 1/2 rotation and then stop. When system was powered off the Blower wheel would not free spin and had resistance. Recommendation is to replace the ECM Blower Motor. If the Control Board does not send the proper signal to the motor then the Control Board will also need to be replaced. Turned off breakers in the Air Handler and pulled the disconnect for the outdoor unit. We will call Amana in the morning to get pricing and availability for the M

Performed cooling maintenance, checked air filter, found clean filter. Blew out condensate trap. Checked voltage, amperage and electrical connections, measured capacitor values, found failed dual run capacitor on outdoor unit. Replaced capacitor. Started air conditioner, checked refrigerant charge and temperature drop across coil.

Performed precision a/c tune up on Bryant heat pump system. Aprilaire 401 air filter is ok. Checked all electrical conections and components. Found blower motor bearings are going bad causing air handler to shake. Called and got price and availability on motor and wheel. Recommend to homeowner to not put money into repair due to age of heat pump. ( homeowner will let us know) checked refrigerant pressures and temperatures at indoor and outdoor units. Heat pump is working ok at time of service.
