Comfort is important to all of us. There's nothing quite like the cold blast of an air-conditioned home on a scorching summer day. And, having a dependable yet affordable air conditioner is equally important, especially with the energy concerns of today. The most popular unit in our lineup is the PA13. One of the great things about this air conditioner is the way it looks. And beneath its surface is a smooth-running, energy saving cooling machine. No matter what your favorite indoor activites may be, you can carry on undisturbed because the PA13 operates so quietly. At the same time, this economical unit conserves electricity at a commedable 13 SEER (Seasonal Energy Efficiency Ratio — the higher the SEER, the better the efficiency). And you can expect the savings to come for years because Payne products are designed, built and tested for long lasting operation. Packaged Products Keeping cool is important, especially during the hot, summer months. That's why Payne is so excited about the PA3P packaged air conditioner. This product puts durability, energy-efficiency and affordability in one convenient package. (And take a look at PA3Z, our less featured air conditioner!) Staying comfortable inside is a top priority, no matter what the weather is like outside. That's why Payne's PH3P packaged heat pump offers everything you need - comfort, durability and energy efficiency - all in one affordable package. (And be sure to check out our other economical heat pump, the PA3Z too!)
