Some years ago, I lived in an apartment that was built in 1999 and though it was an older condo, the place was beautiful and newly renovated.
It was a two bedroom, two bathroom unit with hardwood floors, and the living room overlooked a pond that faced the west, which provided the perfect view for immaculate sunsets.
I really enjoyed living in that space, but unfortunately it came with one major caveat. The HVAC system was old and required constant maintenance, frankly, it needed to be replaced. But my landlord opted to have the unit serviced many times instead. It became a consistent issue especially during the Summers when the air conditioner would stop efficiently cooling the apartment. The A/C technician had to service the system every 3 months and as a result we became acquainted because we saw each other on so many occasions during the year. After numerous service calls, the A/C technician was able to convince my landlord to replace the HVAC system. I was convinced that I would finally have a perfectly functioning air conditioning unit. Unfortunately, within 2 months of replacement, the unit needed service again. After further investigation, the HVAC technician concluded that the unit was losing freon due to a faulty line, a problem that he failed to diagnose on his previous service visits. My landlord was aware of this issue, but the cost would have been enormous, so instead of investing more money to rectify the problem, he decided that it was time to sell the condominium. Fortunately for him, he avoided additional HVAC issues and costs, but I assume the new 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 conditioning woes.
