Maryland Recently completed 12 ton geo system in our historic home

I finally pulled the trigger and had geothermal installed in our home. It definitely took a leap of faith and so far everything has been working well though its only been about 1 month. Our house is old (200+) but with an addition and these internals were the main thing that needed to be replaced to keep it around for the next century. With all of the rebates and tax credits it worked out to be an even better deal as a historic property.

House: 6000+ sq feet above ground
3000 sq ft masonry 2 levels +finished attic + unfinished basement with ductwork built 1760
3000 sq ft stucco 2 levels, unfinished attic, unfinished basement with ductwork built 2000

The new system:
5 -vertical wells were completed 400' each
3 -4 ton CM tranquility 30 units ( 1 package, 2 split)
3- new water heaters connected to the desuperheaters.

The old system:
2 -4 ton AC units
1- 3.5 ton AC unit
1 - 2 ton Mini Split
1- 1 ton window AC unit
3 - water heaters
Radiant heat Oil Boiler more than 50 years old
13 zones


26% federal tax credit
20% historic property state tax credit
25% county property tax credit for historic property
3000 MD energy administration Grant
4500 BGE tax rebate

A good deal in the end.

 

Outstanding!
Be sure to let us know how you get on, moving into winter. My house was built 1890 ish. A youngster compared to yours. I love my geo and would not trade it for anything.
