HVAC Repair Columbia SC | Call Gonzo Heating and Air

A few key signs point to a dirty evaporator coil, a common issue in our area. You might notice your AC is struggling to cool your home, running constantly, or your energy bills have spiked without explanation. Reduced airflow from your vents and ice forming on the refrigerant lines or the indoor unit are also strong indicators. Our Gonzo technicians can perform a thorough inspection and cleaning to restore your system's efficiency and airflow, which is crucial for managing Columbia's heat.

Yes, a failing start capacitor is a very common culprit for that humming sound and failure to start, especially during our peak summer strain. The capacitor provides the necessary jolt to start the compressor and fan motors. When it weakens or fails, the motors can't engage. This is a repair we handle frequently. It's important to address it quickly, as trying to force the system to run can damage the more expensive compressor. Give us a call for a fast diagnosis and replacement to get your cool air flowing again.

We recommend a professional tune-up at least once a year, ideally in the spring before the heavy cooling season. Our Gonzo maintenance visit includes checking and tightening electrical connections, testing the capacitor for proper function, cleaning the evaporator coil to maintain airflow and efficiency, and ensuring the entire system is operating safely and at peak performance. This proactive service is the best way to catch small problems before they lead to a breakdown on the hottest day of the year here in the Midlands.
