A malfunctioning heat pump can’t do what it’s designed to do: keep your home comfortable year-round. During winter, a failing heat pump leaves your family in the cold.

When you call us for reliable heat pump repair in Madison, WI, you’re getting technicians who have spent decades working with these systems. We’ve seen every problem—from refrigerant leaks to faulty compressors to electrical issues. Our goal is to get your system working again efficiently and affordably.
Heat pumps are complex systems with multiple components that can fail. We regularly diagnose and repair these issues:
If your heat pump is low on refrigerant, it won't cool or heat effectively. We locate leaks, repair them, and recharge your system to optimal levels.
The compressor is the heart of your heat pump. When it malfunctions, your entire system stops working. Our technicians can often repair or replace compressors without replacing the entire unit.
Wisconsin winters can cause evaporator coils to freeze, reducing efficiency or shutting down the system entirely. We'll diagnose why this is happening and fix the underlying cause.
Faulty capacitors, contactors, or wiring can prevent your heat pump from starting or running properly. We test and repair electrical components safely and thoroughly.
Sometimes the problem isn't the heat pump itself—it's the thermostat that controls it. We troubleshoot and repair thermostat issues that affect your comfort.
If your heat pump isn't moving air, the fan motor may have failed. We replace fan motors and ensure proper airflow restoration.
Heat pumps go through defrost cycles in winter. When this cycle malfunctions, ice builds up and efficiency drops. We repair defrost controls and sensors.
Sometimes a simple troubleshooting step can identify the problem. If you notice any of these issues, it's time to call us for professional help:
We recommend never attempting major repairs yourself. Heat pumps contain pressurized refrigerant and high-voltage electrical components that require professional certification to handle safely. When in doubt, give us a call.
One question we hear often is: "What will heat pump repair cost me?" The honest answer is that it depends on what's wrong. A simple capacitor replacement costs far less than a compressor repair.

We'll help you understand your options and make the decision that makes sense for your situation. We also offer financing options to make repairs more manageable.
At some point, every heat pump owner faces the question: should we repair or replace? We'll give you an honest assessment based on the age of your system, the type of repair needed, and the long-term value of either option.
We believe in making decisions that are right for our customers, not just what's most profitable for us. If replacing makes more sense, we'll tell you. If repairing is the smart choice, that's our recommendation.
