Sunday morning I walked out into my garage to find two huge water spots in the ceiling. The condensate drain line that comes out of my air handler in the attic had clogged up, and it turns out the contractor who originally installed the system didn't connect the secondary drain line to the drip pan. They ran the pipe for it and everything, but were too lazy to cut it and install a 90° PVC elbow.
It's been 10 years since the house was built, and Alabama's statute of limitations for construction work is 6 years - so having the original idiot that installed it come back and fix it isn't an option. Plus I don't want someone that daft touching anything in my house again.
I need to replace the OSB beneath the drip tray and air handler, since I found mold on its underside when I tore open the garage ceiling. I plan on placing two 2x4s beneath the air handler and lag bolting some hefty screw-eyes into them on either side, and then lag-bolting two more screw eyes into the roof joists above. Then I'll use two ratchet straps rated for the load to lift the whole thing a few inches off the plywood.
Next I'll demo the soaked plywood (I have underside access since I tore open the garage ceiling), slide some new sheets in, and screw everything down. Does anyone see a problem with this plan? Some concerns I had were:
- How much flex will the refrigerant lines have? Enough to lift the whole thing several inches?
- How fragile are air handlers typically? And how heavy are they? (I'm not sure what size mine is off the top of my head - it's a 1700 sq ft home.)
- I may have to add some auxiliary bracing to the roof trusses if they can't handle the load. (They're 2x6s)
I've already had two AC companies give me a $3k quote for the work over the phone, and I have one guy give me a $1,350 quote after looking at the situation first-hand. first two want to disconnect the entire system to do the work, which I think is completely unnecessary. The third guy that gave me the cheaper quote said they'd just have to disconnect the trunk line. Am I crazy for trying this myself, or are they all just trying to rip me off?
