Better air conditioning does not equal humidity control

The new, higher SEER air conditioners do a great job of controlling temperature, but controlling temperature is only Don’t lose profits to portable : part of the story. Their efficiency rating is focused exclusively on sensible load. Today’s units have Sensible Ratios they only do part of the job (SHR) of 0.75 or higher. To achieve higher SEER, many units take up to 8 minutes or longer to reach maximum efficiency Energy efficiency at pulling moisture from the air. Combined with new coil designs that drop the temperature quickly in a home for faster comfort, all of these improvements in temperature control to the air conditioning running less frequently and, Your customer knows there’s a need to control excess moisture.
