Thoughts on the Goodman GSX13 Air Conditioner

It's a 2 ton system gusherb

And yes, the humidity creeps up a bit when I am at work at I put the t-stat to 78. The house will get 80-81 on a typical day w/o the AC running with full sunshine (which we have not had much of lately!)

When I am around all day weds, sat and sun, the humidity is in the range I noted.

Oh, I was reading 1.5 ton somewhere but yeah 2 ton is probably too big for your home. I don't remember your exact square footage but homes these days could easily get away with 1.5 ton up to 1,800 sqft or so if they're not full of windows. Our main levels load calc came in just a hair over 24,000 BTU's needed, its 1,900 sqft and lots of glass on the sunny sides at a design indoor temp of 72 And outdoor temp 92 degrees. The 2.5 ton system could hold 72 well into the high 90s maybe even low 100s.

My upstairs RH can creep up into the mid 50s pretty fast on cool damp days, I have the Honeywell Prestige thermostats dehumidify mode setup so it slows the blower down if RH goes above set point and this summer that feature has been a godsend with all the wet cool days we've had. Usually pulls RH back down into the upper 40s within 5-10 minutes.

Still running good

Had some "hot" by PA standards days recently. The Goodman didn't break a sweat no pun intended. I did finally get some condensation on the suction lines, but I digress.

I am pleased with the performance of this unit. I runs quieter than the WH/Heil at the condo and is quieter, by a large margin, that dad's non eco-certified R22 RUUD heat pump.

Naturally time will tell how well it holds up. Research indicates Goodmans sometimes blow the start capacitors. This is easily changed on my unit. I also learned the indoor coil is all aluminum. Research again indicates this is more reliable than copper but I'll hold judgement until I have had the unit for a while.

Last month light bill totaled $68.16 (220v Union made Bradford-white 50 gal. WH)

West Penn Power, A First Energy company, is charging me 7.3 cents per kilowatt. Also a digital "smart" meter was installed during construction.

That's an extremely good electric rate. Ours is around 10 cents a KWh here, and they plan to raise rates in order to fund a grid modernization by 2020.

Our July usage was the lowest I've ever seen it, coming in at 1,440 KWh's. Usually it's 1,900 for July. It was that cold. I expect August to be 17-1,800 Kwh's.

Well summer is over

and the AC unit gets break. Suffice it to say, it ran very well, kept me comfortable at a reasonable price in terms of energy usage. It is a mixed bag labor wise: the Furance was built in a union plant, the AC was built in a non union plant. Both are in Tennessee!

So now I have one season of AC behind me, getting ready to shift to heat mode. I'll see how the furnace carries the freight this winter. This is my first rodeo with GOodman brand HVAC products. Naturally like anything else, they work fine when new. Time will tell how well they hold up. As I have learned, a good installation is key. You can take a top of the line Trane and do a hack job and will perform like shit and probably give up the ghost before the warranty runs out.

So far as I can tell, my unit was correctly sized and installed. I feel that will go a long way towards satisfactory performance and longevity.
