A good rule of thumb is the “5,000 rule”: multiply your system’s age (years) by the estimated repair cost. If the result exceeds $5,000, replacement is usually the better investment. Other key replacement indicators include a system older than 12–15 years, repeated refrigerant leaks, compressor failure, or refrigerant type R-22. Our technicians will give you an honest, no-pressure assessment during the free in-home estimate.
