A Two-Stage Cooling System Is Ideal For San Fernando, Santa Clarita and Conejo Valley Homeowners

Last updated 1 year ago

For homeowners in the San Fernando, Santa Clarita and Conejo valleys, a two-stage cooling system is better than a single-stage system. A standard efficiency central air conditioner with a single-stage compressor produces 100 percent output 100 percent of the time. 

But only on the hottest days in Southern California — no more than 20 percent of the time — is full compressor output necessary. The rest of the time, you’re just wasting energy, creating noise and putting excess wear and tear on components. High-efficiency air conditioners with SEER (seasonal energy efficiency ratio) ratings over 16 offer a two-stage cooling system. When the cooling load permits, the compressor automatically drops from 100 percent to 67 percent output.

Here’s how that extra stage benefits you:
 

  • Single-stage compressors cycle on and off frequently, producing an “all or nothing at all” cooling effect. A two-stage compressor operating at a lower output runs more continuously and cools more consistently. This eliminates the frequent “off” periods when rooms can rapidly heat up, requiring more energy to cool them down.
  • The compressor consumes less electricity at the lower output stage. The cooling portion of your household electricity costs can be reduced by up to 30 percent with a two-stage cooling system.
  • Systems with two-stage compressors also incorporate a variable-speed blower that runs more continuously, but at a lower speed. This reduces airflow over the evaporator coil, extracting humidity from the air more efficiently than a single-stage unit with a one-speed blower. It also produces less noise — some two-stage units generate less than 69 decibels. 
  • When you need 100 percent cooling, such as when you have to cool a hot house down in a hurry, a two-stage cooling system will sense the high cooling load and automatically switch to full output. High-efficiency technology incorporated in a two-stage unit will cool your home in half the time it takes an older one-stage system.
