Geothermal Cost Factors in SPARROWS POINT

- →Loop type: Vertical loops (150–320 ft deep) cost more but need less land. Horizontal loops require 5,000–10,000 sq ft of yard space but are cheaper to install where land is available.
- →Home size: Most residential systems run 2–5 tons. Plan for $4,000–$8,000 per ton of system capacity, all-in.
- →Getting multiple quotes: Prices from SPARROWS POINT-area contractors can vary 15–25%. Comparing at least 3 quotes is the single easiest way to reduce your cost.
