Q2: Why Does Central Air Cost More in Older Homes?Homes built before the 1970s weren’t designed with HVAC in mind. You may need:

• New ductwork
  
• Electrical panel upgrades
  
• New returns and supply vents
  
• Drywall removal
  
• Asbestos abatement
  
• Reinforced attic platforms
  
• City of Beverly Hills permits
  

These add labor hours and sometimes require coordination with electricians or general contractors.

Q3: Do I Need New Ductwork?70%+ of older homes need new ducts.
Old ductwork is often:

• Not sealed
  
• Not insulated
  
• Too small for modern systems
  
• Leaking 25–40% of conditioned air
  
• Full of dust or mold
  

Cost of New Ductwork:👉 $4,000–$10,000+ depending on home size and access.
While expensive, new ducts dramatically improve efficiency and airflow.

2. High-Velocity Mini-Duct SystemSmall flexible ducts that require minimal wall cutting.
Cost: $12,000–$22,000
3. Ductless Mini-Split System (most affordable)If ducts are impossible, a multi-zone mini-split is the cheapest option.
Cost: $8,500–$18,500 depending on number of zones.
