Beca R.
Responded to no cool call on an 8-year-old residential air conditioning system using R22 refrigerant. Upon arrival, verified system was achieving a 14-15 degree temperature split but unable to maintain desired setpoint. Diagnosed system as low on refrigerant charge, indicating a leak in the system. Advised customer that while recharging is possible, system replacement is recommended due to age, refrigerant type, and recurring refrigerant loss. Customer declined service at this time and will contact for replacement estimate at a later date.

Replaced failed expansion valve (TXV) and RDS control board on Goodman HVAC system. Installed new components, performed verification test to activate RDS settings on integrated furnace control, and adjusted blower speed to match 2-ton system capacity. Evacuated refrigerant lines, recharged system with R32 refrigerant, and conducted operational testing. System now operating within specifications with proper temperature split across furnace.

Trent L.
Completed comprehensive AC tune-up on Lennox condensing unit as part of maintenance agreement. Replaced indoor air filter, verified evaporator drain line proper operation, removed condenser panels and thoroughly cleaned condenser coil which showed significant buildup from four years without service. Inspected electrical components including capacitor (within specification) and contactor (good condition). Addressed homeowner concern regarding unusual noise during unit shutdown, identified as refrigerant flow noise due to dirty condenser coil restricting airflow. System startup confirmed proper operation with 22-degree temperature split across evaporator coil, indicating adequate cooling performance and refrigerant charge.

Ben W.
Responded to no cooling complaint on 10+ year old R22 system that had been recently serviced by another contractor. Upon inspection, determined the thermostatic expansion valve (TXV) requires replacement, likely due to improper installation procedures including failure to flow nitrogen during brazing operations. System also requires installation of RDS mitigation board for code compliance. Documented equipment condition with photos and requested pricing for TXV replacement and required safety component installation to restore proper system operation.

Trent L.
Responded to no-cool call on 2008 Ruud outdoor condensing unit. Upon arrival, unit was attempting to start but failing to run, with audible clicking from contactor and loud buzzing noise. Diagnosed failed capacitor with no measurable capacitance and severely pitted contactor causing poor electrical contact. Replaced both capacitor and contactor with OEM-equivalent parts. Rinsed outdoor coil to remove debris accumulation. Verified proper system startup with 18-degree temperature split across evaporator coil, confirming adequate cooling performance restored.

Colten C.
Performed comprehensive AC tune-up on Lennox system for homeowners who recently moved into the property and were starting the unit for the first time. Upon inspection, discovered system was significantly low on refrigerant charge. Discussed diagnostic findings and repair options with homeowner, who authorized addition of refrigerant and UV dye to restore system operation. Added refrigerant to manufacturer specifications, achieving proper operating pressures with 20° temperature split and 3° subcool. Injected UV dye into system for future leak detection purposes. System now operational and cooling effectively.

Ben W.
Responded to no cooling complaint on one-year-old Goodman system running continuously. Inspected indoor coil and confirmed no freeze-up, though evidence of water on floor indicated previous freezing condition. Connected manifold gauges and found near-zero suction pressure and low liquid line pressure. Identified active refrigerant leak at outdoor unit Schrader valve, documented with video evidence. Performed bubble test on all accessible refrigerant connections with no additional leaks detected. System confirmed low on R32 refrigerant. Scheduled follow-up visit to replace leaking Schrader valve and recharge system with R32 refrigerant once pricing and materials are obtained.

Bryson E.
Responded to a dual plumbing issue involving a leaking Delta shower valve and a clogged kitchen sink drain. Upon inspection, found the shower valve cartridge was failing and causing water to leak from the handle. Replaced the Delta cartridge to restore proper function and eliminate the leak. For the kitchen sink, diagnosed a grease blockage in the horizontal drain section before the vertical drop. The homeowner had previously attempted to clear the obstruction and noted a gel-like substance in the pipes. Used a drain auger to break up the grease accumulation, then employed a blow bag to fully clear the line and restore proper drainage. The blockage was successfully removed from the accessible horizontal pipe section without requiring extensive disassembly of the drain system.

Trevor P.
Completed warranty repair involving replacement of control board due to intermittent furnace operation. Removed undersized damper beneath furnace to improve airflow, as the existing setup featured very restricted ductwork openings. Advised customer that rapid temperature fluctuations are likely due to insulation characteristics of manufactured home and small ductwork configuration, which cannot be easily modified.
