Heat pumps typically last 15–20 years with proper maintenance. After the 10-year mark, efficiency tends to decline and repair frequency increases — so it's worth factoring in annual service costs when deciding whether to repair an older unit. In St. Louis's climate, regular tune-ups are especially important because heat pumps handle both heating and cooling loads. A verified technician can assess your unit's condition and help you decide whether repair or replacement makes more financial sense for your situation.
