“In terms of avoiding the transfer between spaces, you can’t do better than PTAC. It’s just a zone unit.”
Eneref Institute examines the benefits of variable refrigerant flow inverter-driven air conditioners.
“The average efficiency of air conditioners sold today is less than half the efficiency of systems available on store shelves.”
“I love how quick the air conditioner works. You just turn it on and it cools or warms the place inmediately,” says resident Leslie Cook. “It has made life much more comfortable.”
Eneref Institute recommends the use of an energy- efficient, low-flammable refrigerant with a significantly lower global warming potential.
“R-32 is 40% more efficient than R-410A, but with only 1/3 of the global warming potential.”
“Because of the inverter compressor technology, the energy savings you get are unbelievable.”
