John Nicholas replied to Home Energy Magazine's discussion Air Source Heat Pumps Question from ColoradoJohn Nicholas replied to Andrew Aliferis's discussion Affordable, effective and easy to install HRV?"Depends on the home and what problems you are trying to solve.
Existing homes you can identify specific problems that have occurred over time and work on remediation.
New construction, you need to work toward the standard and apply your…"
John Nicholas replied to Pat Dundon's discussion Basements and BAS"Most homes in this area have full conditioned basements. They are finished and used for all types of living activity.
If the basement is intentionally conditioned, you have to include the volume. If it is unconditioned, you really should…"
John Nicholas replied to Andy Simms's discussion Spillage used as pest control to keep spiders away. in the group Hall of Shame"That does not look like a spider on the concrete support. It looks like a rodent!!!"
John Nicholas replied to Tripp Pankey's discussion Add a Supply in the group Hall of Shame"Yes! He sealed the connected connection with Furnace Tape and not 'Duct Tape'! Very seldom do we see this!"
John Nicholas replied to Sean Lintow Sr's discussion RESNET & Confirmed Ratings - no more fake numbers in the group Best Practices (Residential)"Got mine Also! Thank God!"
John Nicholas replied to Craig Bird's discussion Sources for duct insulation savings"REM allows you to estimate the length of supply and return duct based on the size of the home and # of registers. I have never done so, but it also allows you to directly enter the length. On two new Energy Star Homes I measured the…"
John Nicholas replied to Home Energy Magazine's discussion UV light in Furnace?"Indoor air quality starts with a lot of things! The last item you do is filter. Why allow everything into your home and then try to find it and remove it.
Large High efficiency filters at the air handler create more problems then…"
John Nicholas replied to Jack Baikoff's discussion Measuring fresh air intake ducted to a return and no way of measuring from outside."Ted,
Thanks. I had to pull the image of and lighten it up to make out the details down there. It looked like a duct with no bottom in the original."
John Nicholas replied to Jack Baikoff's discussion Measuring fresh air intake ducted to a return and no way of measuring from outside."Ted,
That is a sealed combustion furnace. We don't know what the hot water heater is.
If that is someones idea of mechanical ventilation to meet ES 3.0, I believe they missed a class somewhere. Code compliance for fresh air in this area…"
John Nicholas replied to Jack Baikoff's discussion Measuring fresh air intake ducted to a return and no way of measuring from outside."Set up your blower door and duct pressure testing. Get a duct leakage to the outside, with the vent open. Then repeat with the vent taped off. That would be the amount of air flow in CFM at 25pa through the duct. If you are wanting the…"
John Nicholas replied to Kari Sauder's discussion horizontal venting in the group Hall of Shame"You didn't even need a level to show the negative slope on those. Wow! Scary Indeed! The only thing worse would be disconnected before the chimney - and these might have been!"
John Nicholas replied to George Kopf's discussion ASHRAE 62.2.2010 and the $20 app"OK! In the 89 standard it was simple to get a number. You ran a blower door. Looked at the map, picked an N factor for height and exposure. Since I am near a border of two different zones, and no one has been able to tell me where…"
John Nicholas replied to TJ Ewing's discussion Furnace Blower Fan on 100% of the time - Good or Bad or it depends? in the group HVAC"I consider that in 6. Combustion Pollution Control. It means low level CO monitoring and CO detectors for the high level immediate issues."
John Nicholas replied to TJ Ewing's discussion Furnace Blower Fan on 100% of the time - Good or Bad or it depends? in the group HVAC"Steps to Indoor Air Quality by Priority:
1. Test for and Mitigate Radon as found.

Energy Auditors Rock! They Depressurize!
You’ve been in the attic, the crawl spaces or basement, climbed up and down any stairs several times. There have been some questions from the home owner and perhaps from the kids in the house.
