Factors Affecting Furnace Cost in Dundas
- Older home venting: Many Dundas homes built before 1990 have chimney-vented natural-draft furnaces. Converting to 96% AFUE condensing systems requires PVC sidewall venting — adding $200–$400 but delivering significantly lower gas bills.
- AFUE efficiency: 96% AFUE two-stage furnaces are the best choice for Rice County’s cold winters. The efficiency premium pays back through lower gas bills within 5–7 years.
- Home size: Dundas properties range from smaller older homes to newer builds. Correct BTU sizing prevents short-cycling and energy waste.
- Ductwork condition: Older Dundas homes may have aging or leaky ductwork. Duct sealing before installation maximizes new furnace performance.
- LP vs. natural gas: Some rural Dundas area properties use LP. Goodman furnaces are LP-compatible with field conversion kits.
