    Air returns for a small space?

    One of the guys I talk to suggested adding a return to the bedrooms so the hot air could get out of the room in the event that the door was closed. So I am looking to put a small vent in the bedrooms and hop over the wall and dump it into the common area where the intake grill is for the AC...

    How long should a water heater's hot water last?

    My tenant tells me the hot water doesn't last more than 15 minutes. Its a 30 gallon electric water heater tank. I checked both elements for conductivity, and I checked the thermostats and replaced the bottom one because I thought maybe it needed it. Kicked on the breaker, I can put my ear to...

    Air Quality Hacks?

    I am doing renovations work and the air is full of dust and its driving me nuts. I was going to buy an expensive air purifier for a few hundred bucks, but I did a search and found lots of guys using a box fan with regular furnace filters taped on to clean the dust out of the air. I have...

    One P trap or two?

    I am splitting a bathroom in half and adding an additional tub. The tubs are only a 2x4 apart back to back. Using the existing drain, splitting it in two using a long radius y adapter. So the drains are exactly 32.5 inches apart. Do I need one P trap before it goes into the larger 2" drain...

    Anyone know how to fix a car bumper?

    GF hit something on the highway, it has cracked the bumper cover. No missing pieces, so I was going to just glue it back together and sand and paint the spot and see how close I can get to fixing it for the $500 she doesn't have for a new one. Its a clean crack/split on the bottom of the...

    Romex inside Conduit, I'm sure this is bad.

    I am changing the layout of the kitchen, moving the sink to the island, and will want to have power over there. I can run the bare romex under the floor and back up into the island no problem, but it would be nice to have conduit so I can add wire if necessary and mostly to protect it from...

    I am replacing/relocating the heat pump in my condo, and I am looking to install a new condensate drain. The drain runs under the floor between units and outside the building.

    So I got a buddy of mine who is building a giant garage, but its going slowly because he has a job and no helpers. So I'm trying to install mini-splits but I can't put the hangers on the outside wall because the siding isn't up yet. So I'm trying to hang siding now. I know they need something...

    Preparing a Garage for Storage.

    Two things I am primarily concerned with are Mold and Bugs while storing a long term car project that I just don't have time to work on but I can't let go of just yet. Here is the garage I started with: Its a small garage that is 12' x 20'. One man door, one un-insulated garage door. One...

    Making Compressor Hanging Brackets

    My buddy picked up a couple mini-splits for his garage project and I'm helping him install them. He wants a clear walkway under the eaves so he doesn't have to step over refrigerant lines, so that got me thinking about hanging the compressors from the wall. I could buy wall mounts, or I could...

    Can I get a 60+ foot line set?

    Quick question, can I order Copper line set longer than 50'? I just installed a new AC system in my condo, and it needed roughly 55 feet of line. So now I have 45 foot coil taking up space that I will probably use on the house when the time comes. Can I order a 60+ foot 3/4" & 3/8" copper...

    Why does this Mini Split Freeze up when I don't have it blasting?

    So I have had this mini-split for more than 5 years, and its been great. I turn it on when I go to bed and turn it off when I get up in the morning. Lately I have been leaving it on all day instead of turning it off like I used to. I thought that cranking it up to 80 and just letting it run...

    Do AC Capacitors matter?

    I'm looking at the caps on my 3.5 ton system and thinking its been really hot lately and I was going to order a backup. Looks like I have a 5MF and a 50MF caps, that seems standard. POCFD555 vs POCF5 + POCF50 My neighbors tossed their AC and I scavenged the spare parts and they had a combined...
