Should I repair or replace my HVAC system?

Our repair or replace calculator is tailored to meet homeowner needs and incorporates insights from our Technical Advisors. It evaluates the system’s age, applies a $3,000 repair cost threshold, and considers the system’s warranty status.

• For systems under 5 years old: Repairs are usually recommended especially if there’s an active warranty that covers significant repair costs.
• For systems under 10 years old but older than 5 years: Repairs are typically suggested, as parts might still be covered under a standard manufacturer’s warranty if the equipment was registered and you were the homeowner at the time of installation.
• For systems over 10 years old with a repair cost under $3,000: In this scenario, a repair might still be the best choice, particularly if the repair is for a one-time fix like replacing a blower motor or coil.
• For any system where the repair cost exceeds the $3,000 threshold: Replacement may be more economical, but considerations such as one-time fixes and overall system performance should be evaluated.
• For any system over 15 years old: Air conditioners and furnaces can last up to 20 years, while heat pumps have a lifespan of up to 15 years. As HVAC systems age, they become more prone to needing repairs; however, you may want to weigh the repair cost against the price of a new system, especially if you use your HVAC system less frequently.

For detailed guidance tailored to your specific HVAC system, including warranty details and a comprehensive cost-benefit analysis, consult with our Technical Advisors. They can help ensure that you make the best decision based on your home’s particular needs and the long-term health of your HVAC 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.
