Power Draw Comparison, Rotary Screw Versus Two-Stage Air ,

A quality cast iron / 2-stage pump compressor (Champion/Quincy/Ingersoll etc) with a 1725 rpm motor that operates the pump at around 700 to 900 RPM's will run about 60,000+ hours if properly maintained 10 hours per day x 5 days a week x 50 weeks per year = 2500 hours per year 60,000 hours divided by 2500 hours per year = 24 years of service

What is a Two-Stage HVAC Operation? | Lennox Residential

Two-stage operation, or two-stage cooling, means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days Since the low stage is adequate to meet comfort demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatur
