Technology moves on and it’s true, “they don’t make them like they used to”. Look at your old air conditioning unit, it may appear well built but if it runs on R22 refrigerant not only does it contain ozone depleting refrigerants it also operates on average 40% less efficiently than a new system.
“They certainly don’t make them as they used to, they make them better”. Realistic solutions to the R22 phase out.
