My electrician did not place my mini split disconnect box exactly where I wanted it, and I don't really want to move it b/c it's already screwed in to the hardieplank siding. Is it ok if my mini split lineset crosses the electrical conduit holding the 14/3 wiring? The mini split lineset will...

I'm having a guy with an EPA cert do my mini split turn on, but I don't know if he's ever done a mini split before, so I am trying to educate myself as much as possible so I can help him out if necessary. My unit is a Mitsubishi MUZ-FH09NA. I've attached a couple of pictures. It only has a...

My house has two attached garages, a 2-car and a 1-car. I am turning the 1-car into finished (or semi-finished) space, complete with a ductless mini-split for HVAC. It will be used at least partially as a home office. No cars will be parked in it for the time being, though I could see the...

Installing a Mitsubishi hyperheat 9k unit in the next week or two. Having an HVAC guy do the pressure test, vacuum, and initial turn on, but I'll probably do the rest. 1) Mitsubishi calls for a 3" hole and wall sleeve. What are people using for the sleeve, and where are you buying it? Any...

Picture shows a 13x22 attached garage bay. House was built in 2010 and fully inspected and approved by the local AHJ, and this open wall was previously drywalled until I removed the drywall today. I'm having the walls spray foamed. All that is above this garage is an inaccessible attic space...

I know this may vary somewhat depending on code used, but just curious if anybody can point me to relevant provisions in commonly used building or energy codes. Question is: If I want to add a mini split for HVAC to my attached garage, am I technically required to fully insulate the garage up...

First, let me say I'm not trying to start a controversial discussion. From time to time on this forum when somebody mentions a DIY mini split install, somebody will show up and tell them what they did is technically illegal and requires an EPA cert. Does anybody know for certain whether or not...

I'm moving into a house that currently has an 8-way coax splitter in the telephone/data/video closet. See attached picture. It has a white cable going into a splitter port named "input." I assume that is the main cable line into the house from the cable box at the street. It then has a black...

Since there's so much activity regarding mini-splits these past few days, I figured I would seek the collective wisdom of the forum on this issue. Short version: Would ductless mini splits work for this floor plan (see picture)? Only interested in wall-mounted units. Ceiling cassettes are not...

Bought a house that has an attached 2-car garage, and then separately there is an additional attached 1-car garage, but the 1-car is kind of off to the side like the attached picture. The only way to access the 1-car garage is through the garage door, and there is no living space above it. It...

Let me prefix this by saying I'll be hiring a licensed HVAC tech to do this, but I just want to educate myself first. I want to add a 6-zone ductless mini-split (one condenser, 6 indoor units) to the 2nd and 3rd floors of a house. Four bedrooms on second floor, two additional rooms on third...

Something like this: https://climateright.com/mini-split-4000-12000btu-diy-quick-connect-air-conditioner-heater.html Seems reasonably similar to the MrCool DIY products in that it has a precharged lineset. But the electrical appears to simply be a 3-prong plug. Anybody ever use a product by...

I'm hopefully about 2 months out from building a detached garage. I'm trying to figure out whether it will be possible to connect a bathroom in the detached garage to the main sewer line in my home's basement. The garage will be in the rear of the property. It's a small lot, so the front of...

Is there a rule of thumb for how far to build your foundation from a tree? The tree in question is an arborvitae green giant (something like this: https://www.fast-growing-trees.com/Thuja-Green-Giant.htm). It's probably 6 or 7 feet in diameter, and is fairly mature so isn't growing very fast...

Two questions: 1) I know that Mitsubishi hyperheat units maintain full heat capacity down to 5 deg F or something like that. But is there a limit to the temperature differential that they can maintain? For example, assuming you have an appropriate sized unit, would it be able to maintain a...

House & detached garage below street level...? See attached pic. [Picture deleted--pm me if you want to see it] House and detached garage are several (~3-4) feet below street level, and the front of the lot slopes down towards the house and the garage. The cul-de-sac itself generally is a...

I've attached a picture of a main 200 amp panel that has two subpanels attached to it. One is breaker labeled "subpanel" and the other is the breaker above that labeled "garage." Do those breakers indicate that the bottom subpanel is a 90 amp subpanel? Or does the fact that there are two 90s...

See here for slab cracks: This is the slab of a detached garage of a house I recently looked at potentially buying. It has a loft on top of the garage. Not sure what type of foundation it has. The crack goes clear across the slab starting at garage door. And, as can be seen in video, it...

Assume detached garage is behind my house, about 30 feet away from the main sewer line in the basement of my house. If I want to add a bathroom to the detached garage, could I just run the sewer line from the detached garage into the basement of my main house and connect it to the sewer line...

Random question here. I might buy a pretty standard looking colonial, built in early 2000s, that has an eyebrow dormer in the center of the roof. Extremely similar to this: https://i.pinimg.com/736x/32/2c/29/322c29778d5db4d557cabf4237117c95--house-siding-options-window-styles.jpg. The house...
