How do I know it's not merely a blockage? How would I access the pan to check whether it is a blockage?
Also, I am concerned about "spending good money after bad." If this is a major job costing $1500, should I be considering updating the evaporator to something newer rather than spending $1500 to keep an old, old unit going?
Thanks for your help!
Thanks! The part that confuses me, however, is this:
Last night when it cooled off... I turned the A/C off all night. When I couldn't bear it anymore today in the heat I turned it back on, and it was at least 5 cycles of the A/C going an and off before the leak start again.
So the water problem occurs periodically, not all the time. If the problem were rust, whose location would likely be at the bottom of the pan (not on the side 1" from the bottom), the water would leak whenever the A/C unit is running. But that is not the case. the water leaks just periodically when the unit is running after about five cycles. That suggests an overflow, resulting from the exit being largely, but not completely, blocked.
What do you think?
I do greatly appreciate your help! Nearly done then :-)
Ok, what would I expect to pay for:
1) Overflow issue/blockage?
2) Replace coil?
3) Replace whole evaporator?
4) Replace whole system including outdoor unit?
We currently have 4 ton unit which is honestly a little underpowered for this house in Los Angeles.
Blockage issue around a hundred bucks. Coil is the entire evaporator (Called an evaporator coil). That normaly runs between 1200 to 1600, which is in price range he quoted. New evaporator and outdoor would be in 3000 to 4000 range (depending on size, brand and SEER) And if you decided to replace furnace also, another 2,000 for furnace.
Got it! Thanks for all your help :-)
You have been fantastic and will get glowing feedback and a tip ;-)
Also, along the lines we are currently thinking now, it seems indicative of a partial blockage of the drainage line to the outside of the house along the side of the house. The water that drains there appears to be not as much as I would expect but significant enough that it IS clearly draining.
If there is a partial blockage of this drainage, it would make sense then that the backup when the A/C is periodically cycling during the heat of the day that the partial blockage causes an eventual overflow, but when it's left off for a while, it drains sufficiently so that when A/C is turned back on it takes several cycles to overflow again.
If there is a blockage of this drainage as opposed to a blockage at the evaporator to the PVC pipe, what is the best bet to get the drain cleared?
I've heard about a product named Mighty Pump -- are you familiar and would you recommend this sort of approach?
Ok, last question... LOL...
The blockage is likely to be at the exit of the pan.
How can I gain access and poke my finger in the hole and clear the blockage?
