Question Answers

Why does my Rapid City furnace keep turning on and off (short cycling), and how can you fix it?

Short cycling is common here, often caused by an oversized furnace, a dirty flame sensor, or restricted airflow. It wastes energy and strains the system. We'll diagnose the root cause—whether it's a simple sensor cleaning, adjusting airflow, or assessing your system's sizing—to restore normal, efficient operation and prevent premature wear.

My AC is leaking water inside my Rapid City home. Is this a clogged drain line?

Yes, a clogged condensate drain is a frequent issue in our area due to dust and algae buildup. This can cause water damage and system shutdowns. We perform a thorough drain line cleaning and, if needed, install a safety switch to prevent future overflows, protecting your home and keeping your AC running smoothly.

What HVAC maintenance do I need to prevent common Black Hills problems?

We recommend bi-annual tune-ups. In the fall, we focus on your furnace, checking the flame sensor and heat exchanger to prevent short cycles. In spring, we service your AC, clearing the condensate drain and checking refrigerant levels. This proactive care improves efficiency, prevents breakdowns, and extends the life of your system.
