AC Repair for Creve Coeur's Full Range of Homes


Summer in Creve Coeur regularly brings heat indexes above 100°F, and a failing air conditioner isn't just uncomfortable it's a health concern for families with young children, older adults, and pets. Whether you're in a mid-century ranch near Creve Coeur Lake or a newer build off Olive Boulevard, AAA Home Services has the experience and equipment to get your AC running.


Creve Coeur's older housing stock homes built in the 1950s through 1970s may still have original refrigerant line sets and coils that are approaching the end of their useful life. Refrigerant leaks, coil deterioration, and aging capacitors and contactors are the issues we most frequently diagnose in these systems. Many of these units also use R-22 refrigerant, which is no longer manufactured and increasingly expensive. We'll give you an honest assessment of whether repair or replacement makes more sense for your situation.



For newer Creve Coeur homes with high-efficiency two-stage or variable-capacity systems, we bring the same diagnostic precision to communicating controls, variable-speed compressors, and zoned comfort systems.

R-22 Systems in Creve Coeur's Older Homes



If your air conditioner was manufactured before 2010, it likely uses R-22 refrigerant, which is no longer produced. Sourcing R-22 has become expensive. If your system has a refrigerant leak, we'll walk you through repair vs. replacement options honestly including the long-term cost of keeping an aging R-22 system versus upgrading to a modern R-410A or R-32 system with significantly better efficiency.
