8604 CHELTENHAM CT HVAC permit issued for 5-ton gas furnace and air conditioner

Chapman Engineering Corp is installing a new 5-ton gas furnace and matching air conditioner with full ductwork for the Parobek residence at 8604 Cheltenham Ct. Owner James S. Parobek Jr. lists the project value estimated at $25,000, and calculations dated 11/18/2025 show a heat gain of 54,482 and a heat loss of 94,311 with winter design 13 and summer design 91. The equipment will be in the basement with the condenser at ground level, so it looks like straightforward new-construction HVAC work rather than a big exterior overhaul.
