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…"

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?"

"Correction 32 is the melting point, not the saturation temperature."

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"

"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…"

John Proctor replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good or Bad Idea? in the group HVAC
"Tim, in answer to your questions: 1) Can a 4 ton system with long duct runs cool 2 floors at the same time? a) a 4 ton system that is working properly CAN COOL a well designed and built 2 story house with a floor area of 3100 sq ft. Rick…"

John Proctor replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good or Bad Idea? in the group HVAC
" T. Thornton: Dear T. There are multiple items in your comment that bear some response. First is the zoning issue. I strongly suspect that the reason the house is not getting cooled per your criteria is that the AC is actually delivering way…"

John Proctor commented on Brett Little's blog post Despite record breaking cold winter our MI GreenStar Certified home saved 50% Energy!
"If we want to actually do something about the amount of energy the US uses in heating and cooling buildings then we need to get into them and retrofit them with the things we know works. No fancy simulation programs with a lot of assumptions are…"

John Proctor commented on Christopher Morin's blog post DIY Minisplits: Which side are you on?
"Chris  I think it is way too risky to think these can be assembled on site by homeowners given the experience in other countries and with professionals in the US. On the other hand we need to fix the problem. There is no reason that…"
