After further investigation, the Heating, Ventilation & A/C worker concluded that the machine was losing freon due to a faulty line, a problem that she failed to diagnose on her previous service visits.
Some years ago, I lived in an house that was built in 1999 & though it was an older condo, the place was beautiful & newly renovated. It was a 2 living room, 2 bathroom machine with hardwood floors, & the living room overlooked a pond that faced the west, which provided the perfect view for immaculate sunsets. I entirely enjoyed living in that space, however unfortunately it came with 1 major caveat. The Heating, Ventilation & A/C system was old & required constant service, frankly, it needed to be replaced. But my property owner opted to have the machine worked on more than 2 times instead. It became a consistent issue especially during the Summers when the air conditioning system would stop efficiently cooling the apartment. The air conditioning system worker had to service the system every 3 weeks & as a result all of us became acquainted because all of us saw each other on so more than 2 occasions during the year. After numerous service calls, the air conditioning system worker was able to convince my property owner to replace the Heating, Ventilation & A/C system. I was convinced that I would finally have a perfectly functioning air conditioner unit, and unfortunately, within 2 weeks of replacement, the machine needed service again. After further investigation, the Heating, Ventilation & A/C worker concluded that the machine was losing freon due to a faulty line, a problem that she failed to diagnose on her previous service visits. My property owner was aware of this issue, however the cost would have been enormous, so instead of investing more cash to rectify the problem, she decided that it was time to sell the condominium. Fortunately for him, she avoided additional Heating, Ventilation & A/C problems & costs, even though I believe the modern owners eventually had to invest in getting the lines repaired. I miss living in that condo, the magical sunsets were worth the sacrifice of dealing with those air conditioner woes.
