Arrived on site to perform AC diagnostic on 2014 carrier condensing unit. Upon arrival Joseph states that they moved in approximately 11 months ago and Have had no issues until last night and noticed that the vents are only blowing out room temperature air. Started at outdoor unit and found that it was operational. Proceeded to measure refrigerant pressures and found that the system was extremely low on R410a charge. Verified that there was no signs of leakage outside and proceeded to attic to inspect evaporator coil. Immediately found at TXV Bolt on thread What is loose in the main source of refrigerant and leakage. Properly tightened TXV valve to ensure no more Refrigerant leakage. Returned back to outdoor condenser and inspected electrical and found that duel secondary motor control was weak on compressor side terminal. Also found a single secondary motor control that was added in and left in its original box to power the outdoor fan motor which was leaking oil from its bearing. Jos

Performed fall maintenance on a 2015 York gas furnace. Customer reports no issues with heating so far. Filter was recently changed. Sensors and switches wer cleaned and tested. Gas valve and ignitor were tested and recorded. Heating temperature rise is in range. Primary blower and inducer motor are clean of oil and amping in range. Visual burn marks are present on the control board, this is concerning for the reliability and longevity of the entire system including AC. For this reason I am recommending a voltage regulator and equipment protection. Customer was briefed of the potential issues. System was cycled and running at end of appointment.
