Pricing questions, answered straight
Are these prices quotes?
No — they're typical installed ranges for the Charleston market so you can plan. Your actual price depends on your home and is confirmed in writing, for free, before any work begins.
Why are the ranges so wide?
Because homes are. Equipment tier, ductwork condition, electrical scope, code requirements, and where the equipment lives (attic, crawl space, elevated flood-zone platforms) all move the number. The factors are listed under each project.
How accurate are the monthly payment figures?
They're illustrations using standard loan math at the stated terms — not offers. Goodleap confirms your actual rate, term, and payment at the quote. The 18-month no-interest option reflects our current advertised promotion with a new install, limit one per customer.
Can rebates lower these numbers?
Often, yes — incentives reduce what you finance. See our Rebates & Incentives Center for what currently applies in the Charleston market.
