HVAC Services Dallas GA | Call Sub-Cool Solutions

Yes, a failed capacitor is one of the most common reasons for an AC to stop cooling abruptly, especially during our peak summer heat in Dallas. Sub-Cool Solutions keeps common capacitors in stock for most systems. Our technicians can typically diagnose and replace a faulty capacitor on the same service call, restoring your cooling quickly and efficiently.

The main signs are your heat pump getting stuck in one mode—only heating when you want cooling, or vice versa—or making a distinct hissing sound. Reversing valve issues are complex but repairable. Our expert technicians will perform a thorough diagnosis to confirm if the valve is faulty or if another component is causing the problem, providing you with a clear, upfront repair plan.

We use high-quality, OEM-equivalent parts to ensure durability. We'll provide the specific warranty details for your repair before any work begins, so you have peace of mind.
