HVAC Services Zapata TX | Call Ferny's A/C & Refrigeration

Yes, a failed capacitor is one of the most common reasons for a sudden AC shutdown in our heat. It's a critical component that helps your compressor and fan motors start. At Ferny's, we keep common capacitor types in our service trucks for Zapata homes. We can typically diagnose and replace a faulty capacitor on the same day you call, getting your cool air flowing again quickly.

An iced-up evaporator coil is often caused by restricted airflow (like a dirty filter) or low refrigerant levels, both common issues here. It is a problem that needs prompt attention. Running your system with a frozen coil can damage the compressor. We recommend turning the system to 'fan only' and calling us. Our technicians will thaw the coil, find the root cause—whether it's a leak or an airflow issue—and make the necessary repair to prevent it from happening again.

The single most effective step is to change your air filter regularly, especially during peak summer months. A clean filter ensures proper airflow, which helps prevent evaporator coils from freezing and reduces strain on the entire system, including capacitors. We recommend checking it monthly. It's a simple, neighborly tip that can improve efficiency, lower bills, and help avoid many common breakdowns in our South Texas climate.
