GottyGee, you had to brag. Here's my case study...

Two story home, 3500 sq ft Dallas TX. Equipment 12 years old. Past electric bills - lets not talk about it.

Old Configuration:
-4 tons downstairs
-5 tons upstairs
-Duct taped ductwork, kinks, excessive duct lengths, no mastic
-Average duct leakage
-Improperly sized & balanced supplies and returns
-Condensers against sun exposed SW brick wall

Replaced with:
-5 tons of variable speed Goodman 16 SEER 410A
-10 zones with variable position dampers
-24h Programmable temperature for each zone through web page
-Condenser placed in shade, same SW wall
-New line set per Goodman specifications (1 1/8" & 3/8")
-Engineered R8 Ductwork
-Sealed ductwork

The System was installed 5/17/07, after which several days of ductwork followed (air conditioned attic). The total home consumption from 5/17 to 6/17 was:
1462 KWH / 31 days
47 KWH / day

Average high: 86F
Average low: 73F

The occupied rooms have been set to 77F, unoccupied rooms to 87F (unoccupied daytime 5/days/wk). The kitchen and family room never exceed 81F. The 5 Ton Goodman has plenty of capacity to cool the home down from 87F to 77F at the peak hour. If the humidity ever creeps up above a user setpoint (currently used 65% humidity limit) in the occupied rooms, then the temperature set point is automatically lowered by software, resulting in lower humidity (morning hours).

Being Dallas - August will be the true test. The 77F set point has been a very conservative set point, but the zoning and humidity lowered set point assures that the occupied space is always comfortable and the electricity consumption is minimized.

What’s that thing I keep hearing: Properly installed Goodman…

Now would be a good time to confess – There is a 3HP pool pump running in the back yard; however, it is variable speed, just like the Goodman air handler.
