Fujitsu indoor fan stops when temp reached

Hello, we had Fujitsu ductless units installed few days ago (ASU24RLF, ASU9RLF1). Indoor unit’s fan stops completely on all 3 indoor units when temperature is reached. Does anyone know how to disable this and have the fan run nonstop? The manual specially mentions “The fan will operate at a very low setting during Monitor operation”. https://www.greenbuildingadvisor.com/question/fujitsu-indoor-fan-stops-when-temp-reached


Air Barrier(s) for Unvented Roof Assembly (beams-T&G-plywood- rigid foam-plywood)

Hi all. I’m in the process of building my house with Faswall blocks, a type of ICF. All blocks are placed and filled with concrete and we’ll drop in the roof beams in a few weeks. I’m trying to get my roof assembly dialed in and have several questions. I’ve read the articles posted here on rigid foam roof insulation as well as on buildingscience.com and have consulted with a few friends in the energy efficiency/weatherization business.  I still have few questions as this is my first build and I want to get it right. I live in Wenatchee, WA,…


Insulating around embedded girder beam in basement

Hello, I wanted to insulate my basement walls with 2″ of EPS foam boards, glued to the wall, followed by a 4″ stud wall of unfaced fiberglass batts. Climate zone is 4-5, Maryland.  My question is about insulating around my foundation’s girder/beam joist that is embedded into the concrete block wall (see attached picture). I have seen other articles on here mentioning that insulating around embedded joists is not a good idea, as it increases rot potential, I am curious if this applies to this girder. It is the main girder of the home, therefore supporting much of the house!…

New construction with propane lease and locked in agreement for 2 years

After a year of house hunting, we finally landed a home within a school district of choice. The home is set to deliver in April 2023 and fingers crossed the propane prices drop by then. Not too hopeful on that price drop, so I began looking into this HVAC topic more closely. The home is in the Philly suburbs, so I think Zone 4A. The setup:1. We are tied to propane for heat, cooking, fireplace, water heating (Navien NP240A tank less). Dual zone heat with 2 Lennox ML193UH070 furnaces and 2 Lennox 13 SEER AC units (model 13AC XN030-230-26). I…


retrofit stem wall insulation

We are having a custom home built in cold climate, Zone 6a, with a walkout basement. The slab has 3″ PS foam under a 4″ slab with hydronic heat tubing near middle of that slab depth. Basement walls are mix of 8″ poured concrete and 2×8 framing. While I would have preferred interior insulation of the footings and slab edge, that didn’t happen. The contractor had previously installed 3″ foam on exterior of all concrete basement walls, but nothing similar was done for footing portion of the conventionally framed walkout walls. Of course there will be interior insulation, but slab…
