One, Two and Variable Speed Air Conditioners – Part 3 of 3

Knowing that different air conditioner compressor speeds affect energy efficiency & humidity removal ability, which A/C To Choose Depends On Your Budget, Lifestyle And Home’s Size.

  • For those in large homes, the Platinum Series presents the best value — due to highest energy efficiency (up to 21 SEER).
  • For those who have less flexibility in temperature settings (such as families with young children) — the Silver Series may present the best value (up to 18 SEER).
  • For those who minimize HVAC energy usage by operating the system warmer + setting the thermostat back while the home is unoccupied and at night — the Gold Series may present the best value (rated at SEER 14).

SUMMARY:  

Today’s A/C have different air conditioner compressor speeds. Variable or two-speed a/c compressors match their cooling output with current cooling demand.   This also allows for longer operating times which minimize starts & stops that use more electricity. Longer operating times also minimize the number of times the attic ductwork must be recooled.

Multiple speed a/c compressors run for longer operating periods (at slower speeds).  This gives the a/c enhanced humidity-removal ability. When air passes over the indoor cooling-coil more slowly, more humidity is removed.

The Nest Thermostat has the ability to measure & control both temperature & humidity level.  With multiple-speed a/c compressors and furnaces, Nest can slow the a/c compressor & furnace blower speed for increased humidity removal.  With one-speed systems, Nest will reduce the cooling pre-set temperature to get the system to run longer, removing more humidity.

SUMMARY:  

Today’s A/C have different a/c compressor speeds.  Variable or two speed a/c compressors match their cooling output to current cooling demand.   This also allows for longer operating times which minimize starts & stops that use more electricity than continuous operation. This makes the unit more energy efficient.  Longer operating times also minimize the number of times the attic ductwork must be recooled.

Different a/c compressor speeds allow the a/c to run for longer operating periods (at lower speeds).  This gives the a/c enhanced humidity-removal ability. When air passes more slowly over the indoor cooling-coil, more humidity is removed.
