HVAC Contractor Solutions for Lincoln University, PA

I conducted a thorough cleaning and inspection of the air conditioning system, focusing on both the indoor and outdoor units. The evaporator and condenser coils were meticulously cleaned, and the unit cabinets were inspected to ensure optimal airflow and heat transfer efficiency. All high- and low-voltage wiring and electrical connections were checked for security and defects, with no issues found. The condensate drains and safety controls were tested and verified for proper operation. The system was operated and tested in both cooling and heating modes. Indoor unit readings showed a Delta T of 20°F, and the coil pass was clear of debris. The heating system passed, and the filter was changed. The outdoor unit passed all tests, and a drain pan treatment was installed. Everything is functioning within normal manufacturer specifications.

Work Order TNFR673194 involved diagnosing and replacing a malfunctioning controller. Upon inspection, it was determined that the existing controller was faulty and unable to properly manage the system's operations. The old controller was carefully removed, and a new one was installed. After the replacement, the system was tested to ensure it was functioning correctly. The new controller was configured to match the system's specifications, and all components were tested for proper operation. The job was successfully completed, and the system is now operating as intended.

Upon arrival, I identified that the unit was locked out due to a low-pressure reset. I began by checking the pressure levels, which appeared slightly low. A thorough inspection of both the outdoor and indoor units was conducted to detect any signs of leaks, but none were found. After turning the air handler back on, I noticed that the blower did not activate. Further investigation revealed that the circuit board was faulty, while the motor itself was functioning properly. To resolve the issue temporarily, I bypassed the circuit board, enabling the blower to operate until a permanent repair can be made.

Returned to site to inspect HVAC system installation issues identified during previous visit. Found supply plenum improperly attached to air handler with significant air leakage causing duct wrap inflation—flex collar connection should have been installed between duct system and air handler to prevent air escape. Discovered exposed high-voltage electrical wiring terminated with wire nuts and electrical tape while breaker remained energized, creating immediate safety hazard. Identified undersized heat kit installed compared to original equipment specifications. Documented all findings with photographic evidence and recommended immediate correction of plenum connection, proper electrical termination with breaker de-energization during work, and replacement with appropriately sized 15 kW or 20 kW heat kit to match system heating requirements.

Found breaker in panel box tripped upon arrival. Inspected and tested system operation. Diagnostic readings: ●Refrigerant pumping system RLA: 16.4 amps ●Actual compressor amperage: 10.2 amps ●Outdoor heat pump line voltage: 202 volts ●Voltage enhancement system factory specification: 40/5 MFD ●Actual capacitor reading: 39/5 MFD ●Indoor air handler line voltage: 202 volts ● Delta T 20 degrees Recommend having the electrical panel and power supply inspected by a licensed electrician. Proper operating voltage at both the indoor air handler and outdoor heat pump should be approximately 230 volts. Current voltage reading of 202 volts is below manufacturer recommended operating range. Low voltage conditions can lead to poor system performance and may cause premature equipment failure or damage if not corrected. System is currently functioning at the completion of service.

Performed a comprehensive air conditioning system cleaning and inspection. Cleaned the evaporator and condenser coils, as well as the unit cabinet, to ensure proper airflow and heat transfer. Inspected all high- and low-voltage wiring and electrical connections; all connections were secure with no visible defects. Tested and verified proper operation of the condensate drain and safety controls. The system was operated in both cooling and heating modes to ensure proper functionality. Findings: Filter cleaned and passed. Water removal system passed. Delta T measured 20°F. Coil and heat transfer media were clean, free of debris, and leak-free — passed. Cooling mode passed. Heating mode passed. Fan-only mode passed. Power reduction device #1 measured 244V in / 27V out. 3-amp fuse passed. Thermostat terminals measured 27V. Found a fault in water removal safety system. Cleared partial clog and tested with 1/gallon tou ensure proper drainage. Also installed pan treatment to prevent future b

Furnace cleaning: heat rise was 49. Air filter system was clean and recently changed out by customer. Air movement system looked dirty so I tried to wipe off but nothing would come off. Saw some rust on the fan blades so I’m giving customer and estimate on replacing this piece. All wiring was clean and secure. Drain line was clean and clear of all debris and signs of concern. Cleaned off inside and outside of indoor unit with proper cleaner and wipes. Checked outdoor voltage enhancement system which tested at a 46/4.2uf. Factory spec is a 45/5uf so I’m giving customer and estimate on replacing this piece.checked voltage gateway system which was pitted and making a very loud buzz so I’m also giving customer and estimate on replacing this piece. Cleaned off inside and outside of outdoor unit. System was up and running at normal operation at the end of the visit.
