Zank's Heating & Air Conditioning - Walworth's Expert HVAC Repair

A cracked heat exchanger is a serious safety issue, as it can allow carbon monoxide to leak into your home. Signs include a strange, chemical-like smell (formaldehyde), soot around the furnace, visible cracks on the burner, or a burner flame that flickers yellow instead of steady blue. Our Walworth winters mean furnaces work hard, increasing stress on components. If you notice any of these signs, shut off your furnace immediately, ventilate your home, and call Zank's for an urgent safety inspection. We use specialized tools to detect even hairline cracks that aren't visible to the naked eye.

In the Walworth climate, a poorly installed system often leads to uneven heating and cooling, skyrocketing energy bills, frequent breakdowns, and reduced equipment lifespan. Common issues we find are incorrect refrigerant charge, improperly sized ductwork that restricts airflow, and faulty thermostat placement. These mistakes force your system to work harder, causing premature wear. Zank's follows strict manufacturer specifications and local building codes for every installation. We ensure proper sizing, airflow, and calibration so your new system delivers optimal comfort and efficiency from day one, protecting your investment.

Look for a contractor who performs a detailed Manual J load calculation to right-size your equipment for your specific home—not a rule-of-thumb guess. They should also conduct a thorough duct inspection and explain the installation process clearly, including clean worksite practices. A quality installer, like Zank's, will test system performance after installation, checking static pressure, temperature differential, and refrigerant levels, and provide you with the data. We ensure your system is not just installed, but commissioned for peak performance, giving you peace of mind and long-term reliability through our harsh Wisconsin winters and humid summers.
