Advice on oversized/mismatched tonnage -
Sorry for the graphic title but I'm pissed. Did my contractor screw me?
3-level townhome built new 1999
No basement, ground level entry
I used to have:
Comfortmaker 10 Seer upright split system in ground level laundry room
2.5 TN outdoor / 2.5 ton AC /2.5 blower w/ 50,000 BTU furnace.
System worked but after 10 years, parts started to die, so I figured an upgrade was in order
Now I just had installed:
Goodman 13 Seer upright split system in ground level laundry room
3TN outdoor / 3 ton AC / 4tn blower motor w/ 90,000 BTU furnace.
Contract said it was supposed to be 3 tons all around. But i knew something wasn't right because my new system is loud as hell! After I pulled the serial numbers, come to find out contractors gave me a 4tn blower motor. I hope this wasn't a scratch-n-dent he found on ebaby.
If it was just an oversized blower motor then I wouldn't be pissed, but within 1month of installation, the outdoor comp unit fan broke and damaged the coils. freon had a slow leak. at the inside unit, water isn't draining properly and has damaged basement hardwood and carpet. unit showing signs of rust on the inside due to excessive water. water is all over inducer fan, control board, everything!! it's been happening everyday for last 3 months. i replace 4 towels twice a day to soak up all the water. contractor not returning calls. oh did i mention, that the inducer fan kicks on by itself, and I only have the air on...no calls for heat! (needless to say, I had to physically unplug this fan, especially since water was pouring all over it)
Now that i'm going to have to replace the whole bottom furnace and start on a lawsuit with this Licensed Contractor, i'm wondering about that 4tn blower that i didnt ask for. yeah, air blows through vents stronger, but sure as hell isn't cooler. other than it being louder than I like, what other reasons can you think of that this 4tn is hurting more than helping? electrical bill? efficiency? overcooling/undercooling evap coils?
any assistance is appreciated

hopefully that guy will do the right thing and get u fixed up.
Yes you got shafted, also did you get more than one estimate and did you go with low bidder going from a 50000 btu furnace to a 90000 btu furnace is not acceptable the furnace Will not last will probably trip the high limit switch
Thanks Crispin, I hope so too.

Here's the info on the furnace, i hope the blower can be slowed down to match the rest of the system.
Most likely the sales person for the company just doesn't understand proper sizing and figured that more must be better. This unfortunately is the thought pattern of too many professionals in the HVAC industry, which is why it is important to go with a contractor that is willing to keep up on available HVAC training and not rely on what used to work.
Let's face it, the contractor screwed him/herself as well as the consumer. For less cost to the contractor, the proper sized equipment could have been installed. So many contractors see how little difference there is in cost to increase capacity to the next level that they think they are doing the consumer a favor by installing more then is needed.

No sir. He was licensed and bonded. In fact, I checked his license information and it's still good and current. No Pricing please I went with the middle of the road.

Interesting though, when the inducer motor kept coming on for no reason (since I was only calling for air), it actually pushed the hot water heater exhaust back towards the hot water heater. came home one day and smelled exhaust fumes all in the ground level. that was the other reason i physically unplugged the inducer motor.

i was typing this, i just went to Goodman Warranty site again. Not only does my name not show up under the warranty, but the warranty end date says 2016. I just bought this system in may 2011. I purchased the system with a 10year warranty in mind, meaning the warranty date should say 2021, correct?

With my new system, it's a 'hair' better but not significantly different on the top floor vs the older system. the only difference is that is seems to cool down a little faster, which is good i guess.
why is it dripping water for 3 months? after one day some one shoould of checked it! where is the water coming from?
