New Appreciation for my Goodman

[robertc65]

We had a power outage Wednesday morning as my wife and I were leaving for work. I'm not sure how long the power was off but when I came back home it seems that the AC had been running continuously for several hours. The thermostat was obviously confused as the desired temperature display was blinking 88 and the actual temperature (which was accurate) read 57 degrees. The outside temp was 91. I looked to see if the evaporator or condenser coils were frozen and they were just fine. I had no idea this AC unit could drop the temp so much. In my last house my 2 year old Trane unit could not lower the temp below 67 no matter how long it ran on 90 degree days.

That has nothing to do with the brand. Ever heard of Manual J and D?

Typical of an oversized system. Your home must be pretty humid at normal operating temperatures.

I was one one just like that today oversized by 2 tons. Gotta love those Janitrol/Goodman installers..

Sure are proud of that grossly oversized a/c???

I'll never know if mine can get colder than 74...

I know it has nothing to do with brand but I have been crying on this forum so much about my system I thought it was time to say something positive. Yes it is oversized but I have since added some registers and a return in the unfinished basement (which is in the process of being finished) which has extended my run times somewhat. Before I began to condition the basement the humidity would run around 55% when it was 85+% outside, now I have seen it as low as 45% on similar days. I guess I could say that the chronic oversizing Goodman installer did me a favor since now I don't have to worry about extra capacity for the basement. More than 3 sides of my basement are mostly above ground and I like it cold so it does require significant cooling.

Your ac cools your house to 57 in 91 degree weather. So much for manual j. Your ac must be grossly oversized and your power consumption must make the electric company happy. I couldnt imagine what size ductwork is the house it was to small for the orginal system and then you upsized ac i would be expecting to replace compressor awfully soon.

Thank goodness for Goodman.

At 57 degrees you're approaching a medium temperature unit(refrigerator). You probably have a unit twice as large as needed, and your if humidity is low, you have a flooded evaporator due to no load, which will eventually kill your compressor. Don't blame Goodman when your system takes a dump....

Dang the way I feel right now after a hot, humid hard day in Houston I wished mine would get to 57° oversize, undersized I could care less at this point.

Good luck cleaning up the mold in the walls, caused by condensation in the walls due to keeping the inside temp below the dewpoint of the outdoor air...
