Richfield & St. Louis Park MN Furnace Guide: Inner-Ring Southwest Heating

Furnace Replacement in the Inner Southwest Suburbs

Richfield and St. Louis Park are two of the Twin Cities metro's most densely populated inner-ring suburbs, sitting immediately south and west of Minneapolis. Both cities feature primarily postwar housing stock—1950s and 1960s construction—that has been maintained, updated, and loved by successive generations of owners. With furnaces in these homes now on their second or third replacement cycle, understanding the specific needs of inner southwest metro housing is essential for making smart decisions.

Inner Southwest Metro Housing Characteristics

Richfield

Richfield is one of the metro's densest and most established communities, with the majority of homes built between 1945 and 1965. These ramblers and split-levels are typically 900-1,400 square feet—compact homes that require carefully sized furnaces. The tight neighborhoods and older housing stock also mean:

• Close proximity to neighbors requires quieter equipment (variable-speed or two-stage furnaces run more quietly than single-stage)
• Older ductwork may be undersized or poorly sealed
• Original masonry chimneys are common—evaluate before upgrading efficiency level

St. Louis Park

St. Louis Park has a mix of 1950s-1960s ramblers and a significant amount of 1970s-1990s construction as infill development occurred. The housing stock ranges from small 1,000 sq ft ramblers to larger 2,000+ sq ft two-stories. The broader range of home sizes means furnace selection is more varied here than in Richfield.

Correct Sizing for Inner Southwest Homes

Oversizing is the most common mistake in inner-ring suburb replacements. A 60,000 or 80,000 BTU furnace is often the right choice for smaller Richfield ramblers—many contractors reflexively propose 100,000 BTU equipment, which is oversized for a 1,000 sq ft home and will cause short-cycling and comfort problems. Insist on a Manual J heat load calculation rather than a rule-of-thumb sizing approach.

Typical Furnace Costs

Equipment (factory-direct Goodman): $650-1,200 for sizes appropriate to most inner southwest metro homes. Installation is quoted separately for your home — call (888) 762-1334 for the best savings. Purchasing factory-direct from Furnace Direct saves $500-1,200 on equipment versus traditional HVAC company markup.

Efficiency Recommendations

For homeowners planning to stay 7+ years in Richfield or St. Louis Park, 96% AFUE equipment makes clear financial sense given Minnesota heating loads. The chimney situation is often the practical deciding factor—if your masonry chimney is in good shape and also serving a gas water heater, evaluate the cost of re-lining versus converting to a direct-vent water heater alongside the furnace upgrade. Learn about 96% AFUE installation requirements.

Recommended Goodman Models

For most inner southwest metro homes, the Goodman GMSS96 (two-stage, 96% AFUE) in a 60,000 or 80,000 BTU configuration is the ideal choice—properly sized, efficient, and quiet compared to single-stage equipment. Homes with basements being used as living space or where noise is a priority should consider the Goodman GMVC96 variable-speed for even quieter operation.

Utility Rebates and Incentives

Richfield and St. Louis Park are served by CenterPoint Energy and Xcel Energy, both offering rebates for high-efficiency furnace installation ($200–$400). The federal 25C tax credit provides 30% of project cost up to $600 for qualifying equipment. These incentives meaningfully reduce out-of-pocket cost on 96% AFUE upgrades. (The federal 25C credit expired for equipment placed in service after December 31, 2025, so it does not apply to a 2026 installation.)
