"Thanks for the clarification. I was in PHX last week at a Construction Instruction class (those guys know their stuff, denf worth it!). Without the humidity factor I can see a possibility for this working in this specific application. It would be…"
"I feel this ia dangerous train of thought. And i would consider the examples in there of sizing of systems are more on the very oversized scale. What climate are these referring to? But there is no talk of moisture removal in here. The number…"
"I have done 10 houses with aerobarrier. It is impressive! I thought at first it was a great idea but most likely a scam 2 good to be true. After the second house I was sold. It seals all the problem areas at the source point. Everything I have…"
"Turn those systems off when you leave the house. I have everything on a power strip so I can turn
it off when I leave the house. I am thinking of wiring in a switch to the outlet so its by the door for easy on/off when leaving or coming…"
"Kristoff Irwin had an episode on his Positive Energy podcast about this. He interviewed a guy with the epa (i believe) who is also doing his own research actively on larger systems.
Basically yes it does help but sometimes the cleaning can be…"
"If you are going for just a good system I would stick w the 3pascal limit and would aim for less. Any air not returning to the system from each room will be gained from elsewhere. Most likely outside air, adding load as well. Personally I would test…"
"South Wall. It will have the highest load needed for cooling/heating. the shade from the tree could help the outdoor unit operate more efficiently in the summer.
Look into a mini split with a sensor for hot/cool spots. It will direct airflow to…"
And I would have a system check on the 1st floor 1.5 ton unit to make sure it is performing up to spec. Then look to see if the system was sized right. If its a day care you might have a higher temp load on the system during the…"
"Running a ceiling fan actually heats up air. Allison Bailes has some great articles on it. I would set fans to slowest speed if you are having issues with the mini splits distributing air throughout the room. Otherwise you might be making them…"
"Where are the supply runs located? Look to make sure supply runs are sealed. I would second having a contractor make a filter rack and use cheap fiberglass filters. Ones that look like plastic strands dribbled over each other. It will be less…"
"Oversized A/C systems wont pull out enough moisture from the conditioned air. I would check to make sure the systems are set to the right fan speed. Make sure the filters are clean and appropriate for the filter rack. No merv 12 in a 1inch filter…"
