714 WATERFORD RD replaced furnace with 90% single-stage 100,000 BTU York furnace

Blackburn & Davis Inc. is swapping out the furnace for owner Speed Austin P at 714 Waterford Rd, installing a 90% efficient single-stage York furnace (100,000 BTU / 4‑ton) in the basement with the condenser at ground level. This is a residential HVAC replacement for a single-family home, estimated at $6,039 and noted to require no new ductwork—so it looks like a straightforward furnace upgrade rather than a full system overhaul.
