PECO utility and manufacturer rebates depend on current program, system, and homeowner eligibility. Financing may be available for qualifying customers with approved credit, subject to current lender terms.

When should HVAC replacement enter the decision?

Age is context, not a verdict. Compare safety findings, repair history, parts and refrigerant availability, measured performance, comfort, warranty coverage, and complete written repair and replacement scopes before replacing serviceable equipment.

Which local-home conditions can change installation scope?

Older borough homes may have limited mechanical space or ducts, while larger and newer plans may have zoning and humidity concerns. A proposal should identify the home's actual access, distribution, electrical, venting, drainage, and permit needs.

Compare complete installed scopes

Ask for load-based sizing, matched equipment, efficiency ratings, controls, duct and electrical work, startup measurements, warranty terms, available rebates, financing terms, and total price. Central AC replacement generally ranges from $4,500 to $12,000; standard 80% AFUE furnaces $4,500 to $5,500, 95%+ AFUE furnaces $5,500 to $7,500, and premium two-stage or modulating furnaces $7,500 to $10,500. Compare current program rules rather than assuming an incentive applies.
