7 Rules That Tell You Whether to Repair or Replace Your HVAC System
If you are sitting with a repair quote in front of you in a home on Oenoke Ridge, these seven rules are for you. π‘
First, if the system is more than fifteen years old, any repair is borrowing time, not buying it. π
Second, if you have had two or more service calls in the past three years, the pattern is telling you about remaining lifespan more clearly than any technician's optimism can. π
Third, if the current system carries a SEER rating below 14, a modern replacement will operate measurably more efficiently and the difference in utility costs will partially offset the investment over time. π
Fourth, apply the $5,000 rule: multiply the system's age by the quoted repair cost, and if that product exceeds $5,000, replacement wins on the math. πΈ
Fifth, if your home's comfort has been inconsistent despite repeated service visits, the equipment may be undersized, oversized, or simply no longer capable of delivering what the home needs from it. π‘οΈ
Sixth, if your system uses R-22 refrigerant, which has been federally phased out, every recharge will cost more than the last one and the refrigerant is not going to become cheaper or more available. β οΈ
Seventh, if you plan to stay in the home more than five years, a new high-efficiency system is an investment in both daily comfort and eventual resale value that repeated repairs on aging equipment will never be. ποΈ
