My new house has a stove vent hood with that uses 8" ducts. Where it exits the wall the exhaust duct has one of those hooded vents with a damper in it. When the wind blows, the damper opens and then bangs shut. It's a plain sheet metal damper and does not have a spring. It's loud and annoying...

I had an HVAC company install 24k Mitsubishi mini splits in my new shop. The day after they called and told me it went fine but that I need to replace the breakers with 20a ones. The breakers the electrician installed for those circuits was 25a or 30a, I can't remember which. Wiring was supposed...

I got a quote for two 24k mini splits for my 2260 sq ft shop in Oregon. They quoted two different units and I'm trying to decide which to go with. Daikin 22.0 SEER2, 12.0 EER2, 10.0 HSPF2 R-454B RXM24WVJU9 and FTXM24WVJU9 For $600 more: Mitsubishi 23.5 SEER2, 13.35 EER2, 10.5 HSPF2 R-454B...

A downside to getting an ag exemption to build my shop is that the county considers it commercial. When I was in the planning dept getting the permit they said that the toilet room has to meet ADA specs. The sink's going to be outside the toilet room so its easier to use to wash up. I can find...

The concrete for my pole barn style shop is going to start this week. The contractor wants to use a curing agent. I'd planned on applying a sealer like TS210 after the concrete cured, but the instructions for it say that the surface must be clean and free of the curing agent. Can pressure...

The concrete contractor who is going to pour my shop floor says the local plant has switched to low carbon cement, sometimes called 1L or PLC. Here is a FAQ I found from a company that sells products to make it easier to work with: https://curecrete.com/lowcarbonfaq/ The contractor says that it...

My new house in Oregon is going to have a heat pump water heater. They're a lot more efficient than regular electric water heaters. We also have a separate garage with a small shop area that's going to be used to store and work on bicycles and an upstairs apartment. We need a water heater for...

I'm trying to guesstimate the annual kwh usage for the house and shop I'm getting built in Southern Oregon. 2300sq ft house, 800 sq ft apartment, 2240 sq ft heated and cooled side of the shop. It'll all be mini splits (seven air handlers!). It's all electric, planning for heat pump water...

If you look at a member's profile there's a count of posts, reaction score and points. What are points? What is reaction score? How are they calculated?

The electrician is doing some of the wiring on the shop. I had the idea of running a 120v wire to the a switch by the man door (next to the light switches) which I would use to trigger a solenoid that switches power to the 5hp compressor. When I leave for the day I would flip that switch off...

I'm planning on a 10k two post overhead lift for my new shop. It will be used to lift vehicles from Miata-sized to water cooled VWs to 3/4 ton diesel truck. The lifts I'm considering (Forward I10, Weaver's version of the I10, Challenger CL10A) can be installed in normal or wide, or narrow...

The new house and shop will have a total of six garage doors with openers. Yes I'm fortunate, I know. Or maybe just stupid. The garage's doors are 10x10 and 8x10 (8 high) while the shop's are 12x12. All will be moderately insulated. I want wall mount jackshaft openers for all of them. Are...

My 40x56 shop and attached 40x24 farm equipment storage is 500' from the house. I'm finishing the electrical plan for the electrician and was going to add some smoke detectors. Wifi so I can hopefully get some indication if they're going off when I'm not in the shop. But I got to wondering, are...

The concrete guy I want to use for my shop says he usually does a nominal 4" slab which comes out to 4-4.5" as he works to guarantee the 4" minimum. He says he normally puts in 3'x3'x8" footers where the two post lift will go. The lifts I want to use spec 4.5" depth. If you have to cut out a...

This is in Oregon so reasonably current codes. It'll need plumbing and electrical inspections. Also does the fan need to exhaust out the roof or can it go out a wall? They're 14' high walls if that makes a difference.

We want to put solar and backup (preferably batteries) in the house we're getting built in Oregon. I can find a ton of info on determining the loads on an existing house you're living in and nothing on how to do it for a house that's not finished yet let alone lived in. Just in case anyone's...

The existing garage on our place in Oregon has a ~330 sq ft room next to the garage bays. It's current got a concrete floor. At the back is a set of stairs that lead to an upstairs apartment. The apartment and stairs are going to get some sort of laminate flooring. The downstairs room is going...

It's not too hard to sharpen a flat head screwdriver that's gotten a little rounded off. But can it be done for a Phillips head? I have a couple older ones that I have had for many decades where the edges of the business end have gotten a little rounded off or damaged over the years. A new...

We're considering solar for our house that's being built in Oregon. But I read here https://berthub.eu/articles/posts/the-gigantic-unregulated-power-plants-in-the-cloud/ that most panel+inverter systems connect to the manufacturer's servers to upload data and download firmware. Are there any...

We bought a farm in Oregon! We're idiots. Here's some background: Over five years ago I go serious about building a shop on our 20ac in the Santa Cruz mountains in California. I was getting back into cars from a long spell of mostly working on motorcycles and bicycles, which don't need much...
