is quote reasonable?

changing from open to closed loop on 3ton unit. got price of $12,000 plus taxes for 3 loops 500ft . this includes flow center and hookup. i will have to do trenching and backfill myself and electrical. I live in eastern canada. fair price?
thanks in advance.

 

I paid $20 a foot for closed loops here on Long Island, NY last fall.

 

sunny, was the drilling $20 a foot?

 

Yes, drilling, grouting with bentonite, bringing the pipes into the house and pressurizing them.

 

Is that 3 bores of 500' depth or 3 bores at 250' depth (500' of tube per 250' bore)?

Bores cost ~10 per foot here in FL.

 

this was for 3 trenches 250ft horizontal.
thanks.

 

Expensive

I'm from western Canada, which means 98% of the US is closer to you than me, but that seems expensive. If you are truly doing your own trenching and they are just putting in pipe.

To switch over..
-size ground loop
- size circulating pump
- dig trenches
- install piping
- build header
- pressure test
- add antifreeze, purge, pressurize
- day of interior plumbing
- backfill to grade

Should get all of that for the $ you mentioned.

 

thanks guys for input. i guess this will be a diy project.
