Steven Lewis replied to Bob Blanchette's discussion How does Cycles Per Hour affect real world AFUE?

Steven Lewis replied to Christopher Talarico's discussion Heating with Tankless Water Heater & Hydronic Air Handler vs. Gas Furnace
"It looks better on paper than in real life applications.  Both Amana and Lennox came out with dual heat applicationa that would heat the home and hot water.  Eff ratings on the heating side were about 92-97% and the water heaters were in…"

Steven Lewis commented on Christopher Morin's blog post The Basics: Superheat
"Super heat readings without knowing airflow only gives you 1/2 the equation.  Dirty filters/ low airflow/refrigerant overcharge/low temp in building or low outdoor temp will all affect the superheat of the system.  If the superheat is out…"

Steven Lewis replied to Patrick Michaelyan's discussion Installing additional supply runs from the main trunk.
"You need more information before you suggest what the appropriate answer to the customers problem would be.  Do loads on the house and each floor.  Loads tell you equipment sizing which tells you air flow requirements.  Now you have…"

Steven Lewis commented on Christopher Morin's blog post Energy Efficiency Ratio (EER)
