A single stage Air Conditioner is the most common one in the market. When your home is warm the Air Conditioner turns on and when your home has reached the desired temperature the Air Conditioner turns off. lt may sound simple but simple works, this unit has the fewest parts and typically will run for many years worry free. The single stage Air Conditioner is the most common one in the market today.
A Two Stage Air Conditioner starts at full power and runs until it has reached the desired temperature in you home, from this point the Air Conditioner will switch to low power and focus on maintaining the temperature at the lowest cost possible, at the same time low cooling has been designed to dehumidify the home keeping you much more comfortable then a typical Air Conditioner.
SEER stands for Seasonal Energy Efficiency Ratio. This is the ratio of the cooling output of an air conditioner over a typical cooling season, divided by the energy it uses in Watt-Hours. It may also be called a Seasonal Energy Efficiency Rating. on average you save about 7% per SEER Increase. Because we only use an Air Conditioner for about 4 month of the year we call it SEER.
All Air Conditioners make noise but some are quieter then others, the above chart shows you some comparisons so you can get an idea of just how loud or quiet your Air Conditioner will be. Lennox typically is much quieter then most other brands.
An A/C powered furnace motor will use much more electricity costing you more money and typically is much louder. A D.C Motor will use significantly less electricity and will run much quieter in some cases you won't hear it at all..
How do you know how quiet it should be ? Is it on the side of you home or the back ? Is the unit near your patio set or far away, Maybe it's in the front of your home. Sound only makes a difference if your unit is somewhere close to you otherwise you won't likley ever hear it.
