John Proctor commented on MCX's blog post Think Your AC Won’t Make it Through the Summer San Antonio TX? We’ve Got the Fixes
"Correction -- according to the most definitive study I know of the median life is 20.5 years. 63% of the units were still operational when replaced. ASHRAE Study (Lovvorn N.C., Hiller C.C,2002, Heat Pump Life Revisited, ASHRAE Transactions, 108)"

John Proctor replied to Tom Barrett's discussion How Much Energy Do Building Energy Codes Really Save? Evidence from California
"Well well. I am not Michael Blasnik, but I do know that when statistical analysis results do not correspond to the physical world, then it is time to relook at the analysis. It would be crazy to say all the energy saved in California was due to…"

John Proctor replied to Miguel Orduno's discussion Target superheat formula in the group HVAC
"Yikes -- Folks help me out. I am confused. As I recall, the target superheat for a fixed metering device (orifice/non-TXV) is dependent on the return plenum wet bulb (at the plenum, not in the house because what the air conditioner sees is what is…"

John Proctor commented on Stan Harbuck's blog post A Big Boost For Weatherization: Habitat for Humanity on Deck to Help Out
"Weatherization needs more than just money. It needs to continuously improve its effectiveness."

John Proctor replied to Aaren Stewart's discussion When replacing outdoor unit, is it necessary to also replace the indoor unit?????
"Hopefully Bob was saying the refrigerant was recovered not: "all gone" into the atmosphere. If you have a R22 unit any replacements will have to be R22 equipment. If you are replacing everything you will be putting in R-410A and the…"

John Proctor replied to Aaren Stewart's discussion When replacing outdoor unit, is it necessary to also replace the indoor unit?????
"Aaren  Assuming you are talking about a new condensing unit for an AC there are a few of good answers. 1) Yes if the old indoor coil is from a low efficiency unit and was designed for the same size unit as the new outdoor unit. That is the…"

John Proctor commented on Christopher Morin's blog post Should this Duct Layout be Banned?
"We found with the ducts on the floor of the attic, with smaller ACs, with shorter runs, with the ducts buried in lots of insulation, in hot dry climates, that there is almost no penalty for having the ducts in the attic and it is a lot easier…"

Tom White commented on John Proctor's blog post Bypass Ducts for Zoning -- will they finally die?
"John, I took the liberty of sharing your YouTube Energy Consumption in Zoned Systems video on Home Energy Pros.  Why not join the conversation here or in comments on the video page?"

John Proctor commented on Kurt Shafer's blog post What is your opinion about members promoting products here?
"Kurt: So my question is how does your device work? PSC motors generally do not reduce their power as fast as they reduce their flow. How do you decide what the optimum airflow is?"

John Proctor commented on Christopher Morin's blog post How do You Test a TXV?
"Correction 32 is the melting point, not the saturation temperature."
Jul 28, 2014
John Proctor commented on Christopher Morin's blog post How do You Test a TXV?
"Oh yes one more item. There has to be a combination of water and ice to achieve 32 degrees F. That is the saturation temperature. Ice alone can be much colder than 32 degrees F. ProctorEng.com"
Jul 24, 2014
John Proctor commented on Christopher Morin's blog post How do You Test a TXV?
"Thank you for the nice post. Remember that the important thing is the actual superheat that exists entering the compressor is what we really want to control. Superheat serves only one positive purpose -- protecting the compressor from…"

John Proctor replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good or Bad Idea? in the group HVAC
"Tim, You are welcome. I think what the others' responses were focused on is the concept that the AC should cool down the house in a few minutes from a hot soak. A well designed and installed system will make a dent, but it can't pull it…"
