HVAC Services Harrisburg SD | Call One Hour Heating & AC

A frequently failing pilot light in our South Dakota climate is often due to a dirty or faulty thermocouple, a draft blowing it out, or issues with the gas supply. Our technicians can quickly diagnose the root cause—whether it's a simple cleaning, a part replacement, or checking for proper venting—to restore safe, reliable heat to your home.

Signs of leaky ducts include uneven heating or cooling between rooms, higher-than-normal energy bills, excessive dust, and weak airflow from your vents. We perform thorough duct inspections and use specialized tools to locate leaks, then seal them properly. This improves comfort, enhances indoor air quality, and can significantly reduce your monthly energy costs.

Our comprehensive diagnostic service includes a full system inspection, checking thermostat operation, testing electrical components, assessing refrigerant levels (for AC), examining the heat exchanger and burners (for furnaces), and evaluating airflow through your ducts. This allows us to pinpoint any issues, from pilot light failures to duct leaks, and provide you with a clear, honest repair plan.
