Definition of Efficiency?

[crwdz7]

I am still having a difficult time in deciding on a system for my new home. I was curious what the pros thought the definition of an efficient system. I've gathered that a SEER rating is more of a marketing ploy than an actual measurement of a good system. If an efficient system a properly sized unit with a high SEER (15-16)? Am I better off going with a low SEER (13), properly sized system with a variable speed blower and dual stage compressor for better efficieny and comfort? This may be all dependent on the particular system, but knowing nothing about HVAC, I just feel like I'm not getting the whole story.

.. curious what the pros thought the definition of an efficient system.

SEER is an effective tool for comparison of Equipment

Efficiency = Energy Out / Energy In

Investigate a heat pump / dual fuel. ... Climate / Location ?

SEER is a good comparision number.True you install will not be at those test conditions,but still a good method to compare models/brands.


The design of your new system,load calc,equipment selection,and duct design will determine the effeciency of the installed system.

Since your GC ing your new home.
Make the envelope as efficienct as you can. Then have an acturate load calc done.(can be done from the prints, with the updated values)
After that, picking the right size and efficient equipment is easier.(somewhat)
