HVAC Palm Desert, CA 

Upon arrival, performed a complete follow-up diagnostic evaluation of the American Standard package heat-pump system, Model 4WCC4036A1000A, Serial #2203127201, due to concerns documented during a recent home inspection and a subsequent HVAC evaluation indicating a possible evaporator coil refrigerant leak. Reviewed previous company maintenance documentation and recorded operating measurements for comparison. During the previous maintenance visit, this system was found cooling and operating properly with approximately a 19–20°F temperature differential, and there was no documented evidence at that time indicating an active refrigerant leak or evaporator coil failure. Since the previous maintenance visit, another HVAC contractor reportedly determined that the system was low on R-410A refrigerant, added approximately 2 lbs of refrigerant, and recommended evaporator coil replacement based upon a suspected refrigerant leak and residue observed near the evaporator coil/drain pan. Because app

Upon arrival found bedroom system thermostat was completely blank. Last time out thermostat was operational. This was a new problem upon checking attic was getting 115 going into system checked wiring on new parts and found wire from newly installed transformer was loose and not making proper connection after fixing loose wire and tightened correctly and using electrical tape system started up and started to cool down the house properly double checked all the wires and make sure all the wires were secure. System is cooling properly at this time as well as thermostat working properly at this time.

The completed installation involved the following key tasks: - Installed a 4-ton American Standard Platinum 18 POV Upflow Split Heat Pump. - Relocated the outdoor unit, which included running the line set through the attic and down the wall. - Extended the high voltage supply from its current location to accommodate the new unit placement. - Installed a new line set specifically for the relocation process.

System is low on Freon sent estimate for leak search once client signs estimate for office to schedule

Perform annual AC maintenance on two 2022 American standard platinum split heat pump air handler located inside garage. Changed two 16 x 25 filters located in filter rack. checked amps, volts and cling electrical compartment and disconnect box. Check CDA for systems operation and any faults or error codes. Also check CDA for refrigerant levels, pressures super heat, and sub cool. Flushed condensation line and wash condenser coils. both systems are operating and cooling properly at time of service.

Performed annual AC maintenance on 2022 and 2018 American standard platinum split heat pumps air handler located inside garage. Wash washable filters. Checked amps ,volts and cleaned electrical compartment. Checked CDA at condensing unit for systems operation or any error or fault codes. Checked systems refrigerant levels using CDA for pressures, superheat and subcool. Flushed condensation line and washed both condenser coils. Found all electrical components and refrigerant levels to be within manufactured specifications. Both systems are operating and cooling properly at time of service.

Arrived for recall regarding home not reaching desired temperature following recent partial system replacement. Verified cooling operation and checked temperature/psychrometric readings directly at equipment. Recorded approximately 89°F return air and 60°F supply air, producing approximately a 29°F temperature difference, confirming equipment is actively removing a significant heat load. Checked supply-air temperatures throughout the home. Supply temperatures were approximately 63–65°F near the equipment, gradually increasing into the upper 60s/low 70s at farther registers. Existing manufactured-home ductwork was inspected where accessible. Return ductwork appears minimally/uninsulated and is located beneath the home, consistent with significant return-side heat gain. Additional heat gain is present toward the far end of the home due to substantial window/radiant exposure. Thermostat is also located near an exterior entrance in an area without a dedicated supply register. Cooling equip

Performed annual maintenance in cooling on a Lennox split, followed sequence of operation Changed filters checked amps on compressor and condenser fan motor checked capacitor pressures working at range checked starting amps where high installed compressor saver cleared condensation line rinsed condenser down unit is working to manufacture specification in cooling

Upon arrival found system, K2CF located on roof with a hard lockout due to overheat protection. Cleared error code at thermostat and checked systems operation at condensing unit. Check for any other error codes at condenser. Checked ambient sensor for proper voltage also test drive. System is now operating properly.

Maintenance for cooling on a Lennox upflow 4 ton split system. 20 x 25 x 5 filter located at furnace. Furnace located in garage. Condensation line cleared filter changed. Checked system sequence of operation. Checked compressor amps, checked fan motor amps, checked capacitor, checked, disconnect box, checked Freon and temperature split. Washed outdoor unit down. Upon maintenance noticed dual run capacitor testing weak spoke with client and recommend replace proactively before failure. Spoke with client about the benefits of signing up for HFCC and discounts on repairs. Client agreed and signed. Installed new dual run capacitor and test system operation. System is working per manufacture spec. Home is cooling properly. Client signed up for biannual maintenance via check.

Arrived at customer’s home to move circuit for hvac unit to new location. Changed disconnect out to a weatherproof box and piped up wall to penetrate into attic. Ran romex through attic to new condenser location and piped down exterior wall to disconnect. Landed all connections to complete scope of work for today. Installers will collect payment and test circuit to ensure proper operation of circuit.

Upon arrival, mini split is working properly. Client stated it’s not draining properly upon cleaning out drain line found very little water in line set. Informed client system was draining properly but not keeping up due to very restricted filters in mini split. Cleaned out Condensation line and cleaned out filters. System is now draining properly informed client would recommend doing a maintenance on mini split every year before the summer starts to prevent this issue from happening every year.
