Resolved AC not cooling issues by adding 3 lbs of R-410A refrigerant to a leaking upstairs unit, preventing it from freezing. Restored proper cooling to both floors and verified strong airflow through the attic furnace.

Cleared AC condensation lines, replaced filter, and noted biological growth on coil. Inspected plumbing, tested water, identified a galvanized dead leg, and provided quotes for pipe replacement and a whole-home shutoff valve.

Flushed AC condensate drain line with solution. Verified Delta T, capacitor, and amp draws are within spec. Noted a missing 16x25x5 air filter and locked refrigerant service valves requiring follow-up to verify refrigerant levels.

Inspected toilet and determined a rebuild is needed. Sourced specialized replacement parts from a plumbing supply house and scheduled a return visit for Monday to complete the toilet repair.

Provided a quote for mini split AC service. Proposed repair includes making new flares, performing a pressure test, evacuating the system, recharging with R-32 refrigerant, and replacing 10 feet of 1/4" and 3/8" line sets.

Replaced indoor zone C sensors to resolve error. Diagnosed lack of cooling in zones B & D, finding no communication voltage from the outdoor board to the EEV heads. Ordered a replacement outdoor main control board to complete the HVAC repair.

Vacuumed mini-split drain lines and reattached a disconnected indoor head hose inside the exterior line hide using a hose clamp. Tested all four condensate lines to ensure proper drainage and leak-free performance for this AC service.

Resolved blank thermostat issue during AC service. A clogged filter froze the coil, triggering the safety switch. Verified the drain line and refrigerant charge, then replaced the faulty wet switch to restore proper system operation.

Cleared a clogged evaporator coil drain to resolve an AC water leak, then flushed the line with a cleaning solution. Also identified corrosion on a nearby tankless water heater line for future plumbing attention.

Replaced blower motor, control board, and thermostat on Unit 3 to resolve system freezing. Corrected mislabeled thermostat wiring for Units 1 and 3, restoring proper communication and cooling operation across all systems.

Conducted a leak search on the parlor AC and identified a refrigerant leak in the evaporator coil at two locations using UV dye. Currently preparing a quote for the necessary air conditioner repair.

Diagnosed a loud rattling noise coming from the outdoor unit. Replaced a faulty contactor under warranty, restoring quiet and proper air conditioner operation.

Diagnosed AC not cooling and cleared a stuck valve error. Found low refrigerant levels and located a leak at the bottom of the outdoor coil connection. Preparing a quote for the air conditioner repair and checking warranty status.

Diagnosed inactive system. Reset breaker tripped by prior capacitor failure. Verified capacitor, tested refrigerant levels, and confirmed compressor is running. System is operational but aged; recommended future air conditioner replacement.

Cleaned the outdoor condenser during AC service. Identified a weak 30/5 capacitor and pitted contactor needing replacement. Measured a low Delta T of 13, indicating a cooling issue. Crawlspace coil was inaccessible for inspection.

Reshaped crushed casing on Unit 7 to free the blocked fan blade, restoring operation. Diagnosed Unit 4 with a grounded compressor, burnt capacitor, and damaged wiring; provided quotes for compressor repair and a new air conditioner installation.

Diagnosed geothermal AC not cooling issues at units 110 and 822. Identified faulty fan motors in both systems. Quoted parts and labor-intensive motor replacements to restore proper airflow and cooling performance.

Diagnosed AC not working due to thermostat sensor failures. Bypassed thermostat to confirm system functionality, then completed a warranty thermostat replacement and verified proper cooling operation.

Diagnosed AC not cooling. Found the aged system low on R-22 refrigerant with a corroded outdoor coil. Recommended a new air conditioning installation over costly repairs and scheduled a follow-up visit to provide a replacement quote.

Cleaned mini split filters and coils for HVAC maintenance, verifying a 26°F temp split. Inspected home plumbing for leaks, verified 65 PSI water pressure, and recommended replacing corroded water heater dielectric unions.

Diagnosed AC not cooling; replaced blown fuses and a failed condensing fan motor. Washed the condenser coil and temporarily reconfigured compressors to restore proper airflow and cooling performance.

Completed bi-annual HVAC maintenance and plumbing inspection. Checked sinks and toilets for leaks, drained the water heater, and verified water pressure at 68 psi. Tested system voltages, refrigerant pressures, and airflow temperatures.

Replaced control board on one system. For the kitchen AC, repaired a punctured condenser coil via brazing, pressure tested, and recharged refrigerant. Diagnosed a restricted metering device causing high head pressure; quote pending.

Investigated master bathtub leak in the crawlspace and traced it to a corroded brass drain waste and overflow. Quoted and scheduled the pipe replacement to resolve the leaking pipes.

Searched for AC leaks on the evaporator and condenser coils. No new UV dye was found. Advised monitoring cooling performance, with a follow-up inspection planned during upcoming furnace maintenance to determine if further AC repair is needed.
