Hi -
I had a brand new furnace & a/c installed in Oct 2006. When I went to use the a/c in early May, there wasn't any cold air. The HVAC company came out a few times and finally decided to replace the coil on top of the furnance. They said it had a leak and that is where the refrigerent was leaking from. After the coil replacement, I noticed water around the furnace. They came back out and said that the evaporation pan has a bad weld and that is where the water is coming from. They have offered to replace both the coil and pan again.

My question - is there damage being done to the furnace by the water leak? Should I be pushing for more than replacement of the coil? My arguement is that I paid $9K for something that should work, not something that requires new parts after the first time I use it. Now I'm skeptical of all the equipement (Lenox).

Your help is appreciated!!

Something is wrong with this picture. Those coil pan assemblies should not leak especially since they replaced the coil and then it still leaked water.

I do not believe any real damage has been done to the furnace since this all happened over a short period of time so if they put in a brand new coil and pan assembly vacuum it down properly and recharge it should be OK.

I really hate it when new equiptment goes bad in a short time. It makes you think about weather you got a lemon or not.

You can push/ask for more but they are doing what they should to remedy your problem. Rare for a new coil to leak but not impossible. Sometimes is a bad installation that causes a sweat fitting to leak.

I know you meant to say braze if you were talking about a refrigerant line. Most if not all codes call for brazing of the high pressure refrigerant lines.

Now if it is a copper drain line connecting the pan to the drain you can just use standard 50/50 or 95/5 solder. Most lines we see are all plastic now a days.

First off it sounds like you had your share of bad luck or labor, if it is dripping water at the evap. coil it may well be the pan OR it may be low on refrigerant and iceing the coil. When the coil ices up and melts the condensate may drip past the condensate pan into the furnace. Another thing to look at is the condensate drain line trapped? It should be, Mike.
