One more crawler

[selfemployed]

Removed 12 yr. old Williamson horz. gas through that crawl door, cooling coil, old supply plenum and 55 gal. trash can of paste board boxes and oil furnace part from origional furnace. Installed furnace, coil, pump, humid., plenum and AC cond. Added to old slab because of slope. http://ww2.imagewiz.net/images/hvac/52076_Hpim0277.jpg. http://ww2.imagewiz.net/images/hvac/52077_Hpim0276.jpg. http://ww2.imagewiz.net/images/hvac/52078_Hpim0282.jpg. http://ww2.imagewiz.net/images/hvac/52079_Hpim0283.jpg.

Nice looking job. I hate those crawl space jobs. I have one scheduled later next week, I'm not looking forward to it. However the job I'm doing is A\c only. A/H hung from joists.

[sline-dawg]

"tire tracks across your back , i can see you had your fun "looks good... the bald one will be proud.

[rushin]

Sweeeet!!
I hated crawls so much that I was starting to hate my job.
Then I switched to the darkside(technician) now crawls are hit an miss.
So did you have to lay the plastic down?

[Senior Tech]

It's jobs that look like this that show there are true professionals out there...all you gotta do is find'm!
SWEET JOB!

[selfemployed]

Soreness has gone away. Got another one this week. Airhead -Nice looking lines on your 2 spd. install too. Had my cloths spread out across the basement too. She just put in brand new carpet and painted. Furnace wasn't to heavy after removing blower assembly.

[BaldLoonie]

Beautiful!

Most would dump the hum drain & A/C drain right into the crawl. Good to see the pump. Good idea using a Space Gard instead of someone going down every month to change the filter!

[selfemployed]

Thanks, Sorry about the smug on the space guard.;) Had to use float switch and container instead of aux. drain line. Has a removable lid with trap door in top to check switch. Sterilite 2qt. Varibit will crack plastic but hot 1 1/8" copper makes nice hole for 3/4" pvc. Condensate line use to drain into basement shower.

[Stamas]

****, around here we'd call that a basement!
Nice job. Don't they have to insulate in that area?

[selfemployed]

Would help. Built in 56'.

[BaldLoonie]

We're stuffin the boys in the hole today to remove an electric furnace and replace with same plus coil. It serves a greenhouse right by his front door. Just called them to remind them to take lots of pictures! Only thing the salesman didn't do is sell a media filter :(

It's a nice looking installation from an HVAC standpoint, but let's take a look at the "stand" the unit is sitting on.

Concrete masonary units (aka cement blocks) are not intended to be used in the orientation shown. They have no allowable design strength through the webs along this particular load axis. (The hollows cells should always be oriented vertically).

While the grout cells provide a convenient chase for the condensate piping, and the blocks may give adequate service for the actual weight of the unit, using blocks in this fashion is considered a poor practice from a structural engineering and load-bearing safety standpoint.

Many erstwhile home auto mechanics have been crushed by cars held up (or not help up) by cement blocks oriented in this fashion.

[griff man]

Blocks look good to me; nice and neat looking.
Whats that clear container the over flow is going into I have never seen that.

[billygoat22]

Slick trick with the "micro-drainpan" and float switch

Holy S$!t, Cliff Claven has entered our web-site. I would be more than thrilled to have a furnace installed by you or your Co. Those blocks aren't going anywhere.

...and the color tone of the violet purple poly vinyl chloride pipe adhesive really clashes with the earth tone colors of the single unit residential heating device...don't you think, those who can't...COMPLAIN!

One of the prettiest crawl jobs I've ever seen. It's for sure you have a tubing bender and know how to use it.

[selfemployed]

There are six blocks under the furnace and the statement about which way they should be when building is true. No problem here. The container is a Sterilite 2qt. with a trap door in top and safety switch mounted inside. No where to run aux. drain line to a conspicuous location. I need to quit using primer it does clash but will pass insp. The water heater b-vent and the furnace b-vent tie together and common b-vent into tile lined chimney in crawl space. Had to derate common b-vent capacity and then use vert. chimney height to prove it would work correctly. Meeting inspector at job to see if he agrees, just in case.

[Collin]

I kinda figured you common vented them. Did you confirm the flue is clear from top to bottom? Just a thought.

I for one, love the visual of the condensate pipe running through the brick.:D

[selfemployed]

I did when I common vented the old furnace and water heater after I got rid of the ultra-vent on the old furnace 6yrs. ago. Did check at draft hood on water heater when both were working after I started new furnace. I'll go back and do the visual thing just to be sure and safe. Thanks

[karen2krn]

You call that a crawl space? I'll take that any day over some of these Houston attics in august

[grasshopper]

Looks great for a crawl space job for sure!! I hope you are proud of that job.

We are not allowed to vent the furnace that way here though.

[jason e hvac]

you must work out of a truck looking at the rusty gas fitings.me too.

[hvac3901]

looks really good, but

is that condensate trap vent in the middle of the trap?

[dartbyu]

Question? Why cinder blocks?,Why not use super strut and hang the unit??

[selfemployed]

Some of the pipe fittings were reused must be the last installer didn't get the bubble soap of of them. But yes I work out of my truck. The tee is just for clean out thats why it's caped but if the line was longer I would use an open vent. Cinder blocks just worked for this job some I do use unistrut, as in my post (the last crawler). FYI this job failed inspection. 1- stand pipe 3/4" from B-vent. 2- Not enough pitch on coil drain line. Code requires 1" from B-vent and 1/4" per ' fall on line. I corrected both and it passed. No problem :D

[photon]

looks good

[selfemployed]

Thanks

[the_guru]

very nice work indeed. even tho its in a crawl space u guys dont use a over flow pan under the unit ? we like to use an extra pan somehwhat as a selling pitch,makes the homeowner feel more comfortable,and my self for that matter... i bet it was painful =/... vnj tho,i like alot.

Nice job Scott. One of the better looking crawls that I have seen. Still prefer the basement though! :D

[selfemployed]

Where have you been? raleigh. Glad to hear you haven't fallen off the earth. Hope your summer has been good so far.

[dakers]

Raleigh, Pilot Mountain, High Rock, Greensboro...
Got to go to Chapel Hill and Hillsboro Tuesday and Charlotte late next week. Been "rollin'".

[2hot2coolme]

Crawl spaces are a MOTHER to work in. Especially when draggin all your tools in and the equipment...Fuuuuu#@
Good work!
