Clogged Drain Line Caused Drip outside drip pan
Back in July my AC unit leaked into the ceiling of the 2nd fl. The service people cleared the clog from the end of the pipe by blowing nitronen I believe. No probem since then. I'm puzzled however due to the fact that the drip pan under the unit was not wet at all and the water leaked completely outside of it. The tech was not able to Id the root cause.
I'm facing $2500 in damage - covered by insurance - but am concerned this may happen again. Also ...I have a a 10 yr svc contract with the Co. that instaleld the unit 2 years ago. Any general opinions as to whether they are liable for at least the deductible I'll have to shell out? Unit is Lennox Signature. Thanks.
Info on Mimimum Clearances for HVAC Air Handler Install
First of all let me apologize for not updating you guys sooner. The disaster happened in my office - I've been w/o phone service and w/o internet for the last two weeks since the second floor was in containment; twice for mold abatement purposes. I'm writing this from a local community college and would like some help from anyone that can offer it. The root cause of the water leak was a PVC - sch 40 drain line which was thrown out of pitch apparently by the weight of the ducts that were sitting on top of it. The install is extremely tight. One of the techs said the installers put 15 pounds of .... in a 5 pound bag. Since the drain line had a negative slope water accumulated and over the winter froze. One of the elbows (90 deg on horiz plane) cracked at the top and when the line got clogged this summer the water level rose to the top of the elbow where it was cracked and started dripping a pooling on the ceiling of my second fllor. The water damage is about 5 feet by five feet on the ceiling where the insulation got wet, then went down into a closet (12X8 front face wall had to be stripped) and down into a carpet that was ruined with mold too.
After 2 air tests by an industrial hygienist and work by the abatement crew for the last 10 days, last Friday I still found mold and wet insulation along a 5ft area where the ceiling was cut. Here we go again... There is a lot more to the story ... I'll let you know when the book comes out - free copies for all here!
What I'd like info on now is on the minimum recommended clearances for installation of HVAC units. These are spelled out in NFPA 90A and 90B; so far I've had no luck in getting access to these. Anyone knows what the clearances should be? Generally my unit is installed in the peak of a cape with a steeply pitched roof - don't know the exact pitch. The space between the rafters at horiz plane of the top of the of the HVAC unit is 42". Squatting in front of the long side of the unit the width at the bottom between the unit and the rafters at its widest is 39 inches - this is the space you have to squat in front of the unit, to service it. The "front" (cold air exhaust side) is inaccessble (unless you disconnedt ducting) due to it being littered with ducting. Only one side of the unit is accesible - where the the connections are - drains - liquid refrig etc. Any clues as to whether this is within minimum accepted clearances? More to come.. At this point I'm wondering whether the unit should have been istalled in that tight space at all to begin with. Thanks for your help.
