Since we all burn coal not all my clients want the same.
We are building a energy efficient envelope and have had much debate with HVAC.
Current project is 3400 SF Ranch lots of low e glass
In a nut shell R-30 plus walls and R-60 ceilings with a floor R of 48+, we have a tight home.
Air exchange is planned in multiple ways. With that basic knowledge, here is my quest for knowledge.
We have had a couple different approaches to HVAC, 1 the standard with 2 gas furnaces with ducting all over the place and the 2nd high SEER mini split heat pumps with 2 slim duct units and 3 ceiling cassettes.
What my needing to understand is why all this duct work when a ceiling cassette will do the same job.
Thank you for your input.
