Choosing the Right HVAC System Size for Your Mobile or Modular Home
Mobile homes require precise HVAC sizing. These homes typically have less insulation than stick-built homes and exposed underbelly ductwork, which affects heating and cooling needs.
Our NATE-certified technicians provide free load calculations specifically for manufactured housing based on:
- Mobile home square footage and model year
- Insulation levels (roof, walls, and floor)
- Window type and energy efficiency
- Underbelly condition and ductwork configuration
- Home orientation and shading
- Climate zone and coastal exposure
Mobile Home HVAC Sizing Guide
- 1.5-2 Ton Systems: Single-wide mobile homes up to 900 sq ft. Ideal for older mobile homes with basic insulation.
- 2-2.5 Ton Systems: Large single-wide or small double-wide homes (900-1,400 sq ft). Most common size for manufactured housing.
- 3-3.5 Ton Systems: Double-wide mobile homes (1,400-1,800 sq ft). Needed for larger modular homes or homes with poor insulation.
- 4+ Ton Systems: Large double-wide or triple-wide manufactured homes over 1,800 sq ft, or older mobile homes needing extra capacity.
Note: Mobile homes often need larger systems than stick-built homes of similar size due to less insulation and exposed ductwork.
