Roy Cook Heating & Cooling - Louisville's Experienced HVAC Services

Yes, that's a classic sign of a heat pump reversing valve issue, which is a common repair we handle for Louisville homeowners. The valve is responsible for switching your system between heating and cooling modes. When it gets stuck or fails, your heat pump can't produce warm air. Our technicians will diagnose the valve and surrounding components to provide a precise, long-lasting repair to get your heat working again.

Uneven cooling between floors is a frequent concern in Louisville homes, often caused by issues like ductwork design, insufficient insulation, or an incorrectly sized HVAC system. We perform a detailed evaluation of your home's airflow, ductwork, and insulation to pinpoint the cause. Solutions can range from duct balancing and sealing to adding zoning controls, ensuring every room in your house reaches a comfortable temperature.

One of the most frequent emergency calls we get is for complete system failures during our hottest days, often due to neglected maintenance leading to compressor or capacitor failures. Another is for refrigerant leaks, which cause a gradual loss of cooling power. Regular preventative maintenance with us can catch these issues early and help you avoid a costly, uncomfortable breakdown during a Louisville heatwave.
