What I figured out is the following. The bathroom is less than 50 cubic feet, which supposedly means you use about the same size of fan, which is what is installed (50 cfm, cubic feet per minute). This fan uses a squirrel cage fan system. I vacuumed it out, and then blew it with compressed...

Thanks, both of you. I do have Panasonic "squirrel cage" fans. They are very quiet. I will go into the attic and look to see what the ducts look like. I can't do that until this weekend. When I bought these, I went through the calculations: volume of the bathroom; length of the ducts (and...

We have two small bathrooms that are side by side. One is a 1/2 bath, one is a full (but small) bath. I bought two 50cfm fans for them (in 2015- they are older). We had the ducting installed, and they connected both together and the output went to a soffit. We had the problem that when someone...

Thank you. Sorry for my delay in responding. I was building a home NAS (network attached server). For the last many months, I've been addressing my mother's failing health and have built up quite a list of projects, including these. Anyway, I found this too, which describes whether a...

I've been doing a bit of research...found this: Radon mitigation system info I reset the monometer to zero using his techniques, and then got this: Also realized there's a hidden, huge hole near the pipe, where I could feel air coming in. So, I caulked and spray foamed that...

Hi All, I have my "work" desk in the basement, right where the monometer is for the radon mitigation system. It seemed to have a low reading, and I thought the fan (in the attic, near our bedroom, can hear it in summer/with windows open) was a bit loud. So, I took a picture of the data...

I have a contractor coming Monday to redo our really, really crappy walkway into the house. We have a long driveway, with one lamp post near the house and none after that. The lamp post is near the house, then there's the walkway, then the lawn, which is next to the driveway. I was thinking...

I had the electricians install GFCI receptacles under our deck. They installed one GFCI receptacle that was switched (the entire receptacle is switched) in a single-gang box. They then ran outdoor romex over to a second double-gang box with two GFCIs in it. One receptacle is switched. They...

I like the conduit idea, as It helps to protect the wires.

I'm with you, there. Rented a house with multiple switches where I never did figure out what they did. I gutted a room in my raised ranch and redid a lot of the wiring (which I had inspected by the town). I paid for some of the wiring to get done, as I just couldn't do it all. The...

It's definitely a mixed bag. I like the GFCI on the outside, as then you know there's a GFCI in the circuit. And you know when they trip. They do sell testers, but then you have to test...and find what tripped. For instance, my wife's parents had a house. The box on the deck had a non-GFCI...

Thanks for those comments. When I had the oil serviced, the technician estimated an efficiency of 83% I think. The propane would be 95 percent efficient, so it's going to be fairly more efficient, but not hugely so for the price it takes to get there. And, my wife's brother is a plumber who...

That is good that you got all of that. My situation is a bit different. Dandelion's price was $37,000+ after all incentives. Hyper heat (two heat pumps, one with an air handler in the attic and one in basement, using existing ducting) was $32,000. But the Mitsubishi heat pumps run the air...

Interesting. In CT, I went with replacement of both AC units (one upstairs, one downstairs) with Mitsubishi heat pumps. These are so-called "hyper heat", which maintain high output down to zero. I will have to use our existing oil furnace for heat on really cold days. The geothermal was...

How many switches currently run to the fan? If there's only one, where does the fan part get its power from? Does the power run to the switch then to the fan? Or into the fan, connect to the fan part, then run from the fan to the switch and back up (and connect to the light)? I suspect...
