Anyone know what % of stated capacity is available for sensible load? I'll be talking my my contractor tomorrow to review the results of my HVAC Calc work. His quote was based on a 3 ton down and 3.5 ton up to copy what I have now. I will probably be putting in 4 or 4.5 tons. HVAC Calc manual says A/C units typically have about 72% of stated capacity available for sensible load but I don't know how much this varies across various manufacturers.
Also, I read somewhere that stated capacity is usually at some temperature and that capacity drops at higher temps. Is that true? Does anyone have this data for the Bryant Preferred and Legacy series?
PS I thought this was an excellent article
