FAQs

  1. How do I determine if an HVAC system needs replacement when evaluating a potential flip property?
    Check the system’s age (15-20 years is typical lifespan), inspect for visible rust or damage, verify if it uses obsolete refrigerants like R-22, test the functionality, and review maintenance records if available.
  2. What are the red flags in an HVAC inspection that indicate major problems?
    Strange noises during operation, uneven heating/cooling throughout the house, excessive energy bills, frequent cycling, visible rust or corrosion, refrigerant leaks, cracked heat exchanger, or damaged ductwork.
  3. How much should I budget for a new HVAC system in a flip property?
    Budget between $5,000-$12,000 for a complete system replacement, depending on home size, system efficiency rating, and regional costs. Additional costs may include ductwork repairs ($1,000-$5,000) if needed.
  4. Should I repair or replace an aging HVAC system when flipping a house?
    If the system is over 15 years old or repairs would cost more than 50% of replacement cost, replacement is usually more cost-effective and attractive to buyers. New systems also offer better energy efficiency and warranty coverage.
  5. What HVAC efficiency ratings should I look for in a replacement system?
    Look for minimum SEER ratings of 14-16 for air conditioners, AFUE ratings of 90% or higher for furnaces, and HSPF ratings of 8.2 or higher for heat pumps to meet current efficiency standards.
  6. How do I assess the condition of existing ductwork in a flip property?
    Check for visible damage, gaps, or disconnections, test for air leaks, inspect insulation condition, look for signs of mold or debris, and verify proper sizing for the system capacity.
  7. What permits are required for HVAC replacement in a flip project?
    Most jurisdictions require mechanical permits for HVAC replacement. Check local building codes and permit requirements before starting work, as unpermitted installations can cause issues during inspection or sale.
  8. How can I improve HVAC efficiency without full system replacement?
    Install programmable thermostats, seal and insulate ductwork, clean or replace air filters, service the existing unit, add zone controls, and ensure proper insulation in the home.
  9. What documentation should I maintain regarding HVAC work in a flip?
    Keep all permits, inspection certificates, warranty information, maintenance records, contractor invoices, and energy efficiency ratings documentation to provide to potential buyers.
  10. How does HVAC system condition affect property appraisal and sale price?
    A new or well-maintained HVAC system can increase property value by 5-10%, improve energy efficiency ratings, reduce buyer objections during inspection, and potentially speed up the sale process.
