  • Our repair or replace calculator uses the $5,000 rule, a widely recognized guideline in the HVAC industry, to help you decide whether to repair or replace your HVAC system. To use this rule, simply multiply the age of your system by the estimated repair cost. If the result is more than $5,000, it’s generally more cost-effective to replace the system; if it’s under $5,000, you might consider repairing it. However, your decision should also take into account factors such as the system’s frequency of use, its energy efficiency, and any remaining warranty coverage, as these can significantly influence the overall value and long-term cost-effectiveness of your decision.

    Here’s an example of how to use the $5,000 rule:

    • Cost of repair: $500
    • Age of unit: 12 years
    • $500 X 12 = 6,000 (the result is more than $5,000 so replace the system)
  • Minor HVAC repairs costing less than $500 generally warrant a repair, unless your system is older and frequently breaks down. In these cases, applying the $5,000 rule can help you decide whether to repair or replace your HVAC system.

  • Always check your warranty first. If it covers the needed repairs, especially costly parts or labor, HVAC repair is likely your best choice. However, if repair costs approach 50% of the price of a new system, consider replacement, particularly for older models.

  • An HVAC system typically lasts about 10 to 25 years on average based on factors such as usage, maintenance history, and the climate you live in. In moderate climates with less extreme temperatures, your HVAC system may last longer due to less strain on the equipment. Meanwhile, units in regions with more extreme weather may experience accelerated wear and tear, leading to a potentially shorter lifespan. Performing regular maintenance and making timely repairs is the key to improving efficiency and prolonging the life of your HVAC system.

  • Watch for reduced airflow, high energy bills, difficulty reaching desired temperatures, and frequent on-off cycles. These are signs your system may be becoming less efficient and could need HVAC repair or replacement.

  • Efficiency is measured by SEER, AFUE, and HSPF ratings. Older systems or those with low ratings use more energy, resulting in higher utility bills. If your system’s SEER rating is below 10, consider replacing the HVAC system to reduce energy costs. As a rule of thumb, if your system is older than 2006, your SEER is most likely 10 or below.

  • If your HVAC system uses ozone-depleting R-22, the high cost of this phased-out refrigerant combined with any significant repair needs often makes replacement a better option (and sometimes necessary if you can’t find the required refrigerant). Replacing an HVAC system that uses R-22 can save money and reduce your environmental impact.
