My apollo hydroheat evaporator coil has been leaking condensate water directly off of the coil and onto the floor (not the drain pan) below.
Unit is an apollo hydroheat 2.5 ton M 42, installed around 1993/94. Vertically mounted "A Frame" style coil on first floor with hot water heater in basement below appx 16 feet away.
Unit is 1800 sqft brick townhome center unit located in southern PA.
I think this has a been a problem since the house was built in 94.
This seems to leak much more on hot spells when the AC is running fairly continously for several days. I drilled a 1/4" hole in the floor board so that the water goes into a 5 gallon bucket in the basement below.
During these hot spells where temps are above 90F for several days, the unit can never keep the house less then around 80F.
I've had several HVAC tech's look at the unit including check charge, clean the coil, increase the fan speed.
I'm running out of options and money with solving this problem and am hoping someone here has more experience or insight. The one tech suggested replacing the coil, but also said he couldn't find anything wrong with the coil and that it would be very expensive.
Any help is greatly appreciated. I'm somewhat knowledgable with A/C systems (I'm a controls engineer for York Process Systems) so if you know of things I could check please advise.
