    Repair or Replace: Common Questions

    How long does an HVAC system last in Southern Maryland?

    Most central air conditioners and furnaces last 12 to 15 years. Heat pumps run year-round in Southern Maryland’s climate, so they often wear out a little sooner, typically in 10 to 12 years. Regular maintenance is the biggest factor in reaching the high end of that range.

    What is the $5,000 rule for HVAC repair or replacement?

    Multiply the age of your system in years by the repair estimate. If the result is more than $5,000, replacing the system is usually the better investment. For example, a $450 repair on a 13-year-old system works out to $5,850, which points toward replacement.

    Should I replace my system if it uses R-22 refrigerant?

    R-22 refrigerant is no longer produced in the United States, so any repair that needs a refrigerant recharge has become expensive. If your system uses R-22 and needs a major repair, replacement is usually the more cost-effective choice."

    Will a new HVAC system lower my energy bills?

    In most cases, yes. Systems more than 10 to 15 years old are far less efficient than today’s high-efficiency equipment. Homeowners replacing an older system often see noticeably lower heating and cooling costs, especially when the new system is sized correctly for the home."

    Does Tri-County Aire offer financing for a new system?

    Yes. Tri-County Aire offers special financing for qualified customers on new Trane heating and cooling systems. Call 800-890-5123 to ask about current offers.

    Is the Repair or Replace tool a substitute for an inspection?

    No. The tool gives you a quick starting point based on your system’s age, repair cost, and warning signs. A Tri-County Aire technician can inspect your equipment and give you an honest recommendation. We won’t push a new system when a repair makes sense.
