Rising Sun Comfort Solutions | Certified HVAC Repair in Columbus, WI

Frozen components on a heat pump are a common issue in our climate, often due to refrigerant issues, airflow restrictions from dirty filters, or malfunctioning defrost cycles. First, turn the system to 'fan only' mode to help it thaw safely—never use sharp objects to chip away ice. We recommend calling us for a diagnosis. Our technicians can assess the root cause, whether it's a simple filter change or a more complex refrigerant charge adjustment, to prevent future freeze-ups and protect your system.

Our motto means we provide transparent, fair quotes without hidden fees. With 23 years of design and installation experience, we efficiently plan projects—from ductwork to full system replacements—which helps control costs. We pass those savings on to you. You'll get a quality installation for your Columbus home or business at a competitive price, with the confidence that our focus is on your long-term comfort, not an upsell.

Regular maintenance is key to preventing major repairs, improving efficiency, and extending the life of your system, especially with our variable Wisconsin seasons. Our maintenance service includes checking refrigerant levels, cleaning components, inspecting electrical connections, and ensuring your thermostat is calibrated. This proactive care helps catch small issues, like a failing thermostat sensor or worn parts, before they lead to a breakdown, saving you money and discomfort.
