2 stage compressor heat pump. Well two stage heat pumps run more often while using less energy. Two stage scroll compressors for many years hvac manufacturers used two compressors in their higher efficiency equipment to stage the air conditioner or heat pump for added efficiency. The most efficient single stage air conditioner is the lennox sl18xc1 with a top rating of 18 5 seer. One of those is two stage cooling and its demand by homeowners is rising.

The technology is getting better so the current seer range for single stage acs and heat pumps is 13 on the low end. Two stage compressors are more efficient because they run on low most of the time. Now that you know we definitely encourage you to opt for the two stage heat pump. I have quotes for both the standard 14 seer unit.

Since the low stage is adequate to meet household comfort demands 80 of the time a two stage unit runs for longer periods and produces more even temperatures. Two stage units don t run as continuously as a variable speed ac but they do cycle on and off less frequently than single stage systems. High full blast and low for milder days.

Better and more expensive models are heat pumps equipped with two stage compressors and these can operate at the full power 100 or at lower level 60 70 while the efficiency is up to 40 higher. It runs a lower stage most of the time then activates the secondary stage when maximum performance is needed.
