What Causes Most AC Problems

McKinney’s long, hot summers and heavy humidity put a lot of strain on cooling systems. Units run longer and harder here than in milder climates, which means components like compressors, capacitors, and coils wear out faster than homeowners might expect.

Dirty air filters and clogged coils are two of the most common culprits behind AC issues, since both force the system to work harder just to keep up. Low refrigerant, electrical problems, and worn fan motors also show up often, especially in systems that have gone a season or two without maintenance.

Age matters too. Older systems tend to develop more frequent issues as parts wear out, and once a unit passes the 10- to 12-year mark, repairs can become more frequent and more costly. Staying on top of small problems early is the best way to avoid a bigger breakdown later.
