Robert H replied to Hal Skinner's discussion An example of what an RCC can do with no R- insulation in the walls.
"I am a skeptic.  I think there was probably a lot of air sealing benefit.  As we know air sealing is the place to start. If you didnt do before and after testing how much benefit can you assign the the RCC and how much was air sealing.…"

Robert H replied to Howard Katzman's discussion UV lights on filters
"Uv lights do not create any byproducts.  You may be thinking about ozone. Ozone has some good uses in UNOCCUPIED buildings,  Ozone will damage many things so regular use is not a good thing  but if you have smoke or other odors you…"

Robert H replied to Howard Katzman's discussion UV lights on filters
"How do you measure what they prevent? For some people they can make a difference and others they may not see a noticeable diference. I would not put one in a filter box.  I would mount it above the coil.  I think in some circumstances…"

Robert H replied to Howard Katzman's discussion UV lights on filters
"Was there a catalyst?  For disinfecting you are looking at UVC not UVA. I have seen systems that UVA  activates a catalyst. UVC is used in hospital operating rooms and have been shown to reduce the infection rate. UVc is effective at…"

Robert H replied to Tom Conlon's discussion Whole House Fans - Love 'Em or Not?
"I think it boils down to how well the hatch is insulated and sealed. If the hatch is sealed tight and insulated to the same level as the attic floor then it would work in many climates. I think the proper way to do it would be to depressurize the…"

Robert H replied to Craig Bird's discussion What is COSTCO doing?
"Jerry that is a lot of twisting of facts.   Radiant barriers work on one of the 3 methods of heat transfer. It does nothing to stop convection or conduction. So it works during daylight hours when the sun is beating down on a roof. Radiant…"

Robert H replied to Home Energy Magazine's discussion UV light in Furnace?
"That sounds like a ozone generator.  I always advise against introducing ozone in to an occupied building.  Ozone is a very caustic gas, that is why it can clean surfaces. Putting this system in a small room could elevate ozone to very…"

Robert H replied to Home Energy Magazine's discussion UV light in Furnace?
"$400 is over priced.  What you should know about furnace filters is that they should only do a marginal job of removing air borne particulates.  The more you filter the more you restrict the air flow and hurt the efficiency of your…"

Robert H replied to Gordon Smith's discussion Duct Cleaning? Good value or a waste of money?
"Bob   4 inch filters are not a better filter, they have more surface area and last longer.  If you look the the MERV rating of the 4 in filters they are in the range of an 8 or 10. That is mid level filtering. Furnace filters are a…"

Robert H replied to John Murphy's discussion Pros and Cons of Selling House
"Selling a house as is means you are not willing to do any repairs that the seller may request.  You are still required to tell a prospective buyer and know conditions.   Most states have a seller disclosure form that tell you what needs to…"

Robert H replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?
"Scott Its a spray caulk to be used for air sealing. It is only meant to be applied at the seams.  It takes a $1500+ paint sprayer. Same for the Knauf Eco Seal."

Robert H replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?
"That is a horrendous job of installing batts.  A perfect example of why I would never use batts. If you look in the picture you see a thicker bead that sticks up from the framing.  Then at the top of the picture it is very thin.  I…"

Robert H replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?
"I spoke with a builder who has tried both the Owens product and the Knauf product.   They quit using Owen. It sprays on and bubbles up a little. He couldnt get a good surface for the drywall to sit on. I cant remember all the particulars but he…"

Robert H replied to Timothy Renz's discussion Indoor Humidity Levels
"Something to remember is that newer high SEER AC's have a higher coil temp than the unit it replaced.  This reduces the ability to dehumidify. If you compare a new A coil you will see that they are larger than old A coils.  More…"

Robert H replied to Joshua Knittel's discussion Correct way to install foil faced insulation blanket in attic in the group Best Practices (Residential)
"I would say that radiant barriers in the midwest are a waste of money. Radiant barrier work best when there is little insulation.  Do some research and you will see home that have an R value of less than 20 will see the greatest benefit.…"

Robert H replied to Sandra K. Adomatis, SRA's discussion Article on Energy Audits
"I dont know if it was good or bad.  Most said they dont push an audit.  They only cite 1 case of an audit.  Based on the comments it is really hard to tell what impact it had on the sale.  Yes they provided an audit and did some…"
