Q&A
Why does my AC compressor overheat so often in Edinburg?
Our intense South Texas sun and high summer temperatures cause AC units to run constantly, putting immense strain on the compressor. Common local causes are dirty condenser coils restricting airflow, low refrigerant levels, or a failing fan motor. AJs technicians perform a thorough diagnosis to pinpoint the exact issue, clean your system, and make repairs to prevent future overheating and compressor failure.
What are the signs of a failing AC capacitor in my home?
In Edinburg, a failing capacitor often shows itself with your AC unit humming but not starting, random system shutdowns, or reduced cooling power. You might also hear a clicking sound from the outdoor unit. This is a common repair we handle. Replacing a faulty capacitor promptly can prevent further damage to the compressor and restore full cooling function to your system.
How can AJs help prevent these common AC failures before they happen?
Our preventative maintenance service is specifically tailored for the Edinburg climate. We clean condenser coils to prevent overheating, check electrical components like capacitors and contactors for wear, verify refrigerant levels, and ensure all moving parts are lubricated. This proactive care helps your system run efficiently, reduces strain, and can prevent up to 85% of common breakdowns during our hottest months.
