How long should your HVAC system last in Charlotte? Honestly, it depends. Overall, you should maintain your system no matter th season!
Most systems last between 10 and 20 years, but age alone doesn't tell the whole story. We've seen 12-year-old systems still running strong because they’ve been well cared for, while some 6-year-old systems are already struggling due to a lack of maintenance. The key question isn't, "How old is it?" but rather, "How is it performing?"
In North Carolina, a hot & humid afternoon can put a significant strain on your air conditioning and heat pump. So, once your system passes the 10-year mark, it's essential to monitor it more closely—especially before a hot August afternoon forces an unexpected decision.
Wondering what signs to watch for? We have put together a detailed breakdown on our blog. Be sure to check it out!
