"Thanks for the 6 step process. I never thought of this as a way to diagnose this. Yes - I have seen the best companies and the best technicians ignore the use of nitrogen while brazing. It is like not wanting to use duct mastic,…"

Christopher Cadwell commented on Christopher Cadwell's blog post Super Efficient HVAC is Easy
"You have to use judgement on reducing quantity of registers. If the entire duct system is going to be replaced, then use as few as possible.  If you are pushing the limits on the sizing of equipment it is also important that the registers and…"

Bob Blanchette commented on Christopher Cadwell's blog post Super Efficient HVAC is Easy
"I've been looking into reducing duct/register count in my own home. With 3 bedrooms and 1 large living/dining/kitchen area I don't see how this could be done with less than 4 registers. Currently there are 2 registers in the living room…"

Bob Blanchette commented on Christopher Cadwell's blog post Part 1 of: The "1-2 Punch" to HVAC "Not Understoods"
"Bringing ductwork into the conditioned space would go a LONG way to making things right. New houses could be designed with ductwork sizes specked into the building plan instead of just having the HVAC contractor wing it."

Christopher Cadwell commented on Christopher Cadwell's blog post Part 2 of: The "1-2 Punch" to HVAC "Not Understoods"
"If an AC contractor told me that it would not blow enough air, then my response would be to ask for the calculations to show me that there is more cfm needed. Of course they usually cant. So then ask them how they can make an assertion about…"

"I have tried getting HVAC contractors to spec smaller units after deep energy retro fits.   But they claim the code still requires a certain heat load to be used.  Another response is the house can use a smaller Ton unit but the…"

Part 2 of: The "1-2 Punch" to HVAC "Not Understoods"

Proper sizing of HVAC equipment is smaller, and smaller means more comfort.Probably the usual thought in the HVAC industry by technicians is that the units need to be made bigger for comfort. Perhaps this comes from the idea of coming home from work, and needing a set back thermostat to do its magic, and get the home comfortable fast, before dinner.What happens when we add too many Btuh to…See More
