Want to put a firing range in your basement? You should probably test the STC (Sound Transmission Class)  of your existing structure.

What not to store in a server closet

About a year ago we completed a install at a clients small office (20 users).  The install went great, everything went very well, the install was very clean.  We warned the client we needed A/C for the closet, and could do it for a nominal cost, but they were insistant that they didnt need it.  So we told them to keep the room free of, well everything.....  So this is what I came upon when I opened the door ( wich has vents in it, but they were blocked...by 5000 styrofoam cups)... 

How to build your own attic fan...from an old furnace.

I recently finished replacing my entire HVAC system.  After I was all finished with the install I had a few things left over,  It bieng summertime I figured an attic fan for the garage would be smart. 

I started by stripping down the unit. I removed the heat exchanger, blowers, and everything that was not the frame.

 Then I removed the top of the unt where the heat exchanger used to live.  At this point I cut out a hole in the bottom of the unit 1/2" smaller than the air cleaner box. The unit used to take in air from the side, so I used a chunk of the scrap steel from the top of the unit to cover the hole.

 Next, comes the fabrication of the small chunk of duct work from the air cleaner grill/filter holder to the unit mounted above the rafters.

 After cutting out the hole for the aircleaner I mounted the blower above the rafters, and caulked the aircleaner to the bottom of the blower enclosure.

 Wiring the blower to a switch installed in the garage was next.

The blower/attic fan installed in its final position.  

Adding the filter and closing up the intake.

First Blog!

I decided to start posting after a number of people suggested other people might find the things we build, install, and configure mildly intresting.  So on with the show.
