A&B Air Conditioning - Tyler's Best HVAC Repair

Common signs include your outdoor AC unit humming but not starting, frequent system shut-offs, or a noticeable delay when cooling kicks in. In Tyler, our intense summer heat causes AC systems to run longer and harder, putting extra strain on capacitors. This frequent cycling accelerates wear and tear, making capacitor failure one of the most common HVAC repairs we see locally.

Short cycling is often caused by an oversized unit, a dirty air filter restricting airflow, or a malfunctioning thermostat. In our Tyler climate, a refrigerant leak or a frozen evaporator coil due to high humidity can also be culprits. This constant stopping and starting wastes energy and causes undue wear. Our technicians can diagnose the root cause, which is often a quick fix, to restore efficient operation and prevent further damage to your compressor.

Regular maintenance is key. We recommend a professional tune-up twice a year—before summer and winter. This includes cleaning coils, checking refrigerant levels, testing capacitors and electrical components, and ensuring proper airflow. For homeowners, consistently changing your air filter (every 1-3 months) is the single most effective step. This simple habit helps prevent overheating and strain on components, reducing the risk of the capacitor failures and short cycling we frequently repair.
