Harrell Refrigeration Service | Professional HVAC Services in Metairie, LA

Uneven heating or cooling is a common issue here, often due to a faulty thermostat, wiring problems, or sensor errors. First, try replacing the batteries and ensuring it's level and clean. If the problem persists, our technicians can diagnose whether it needs recalibration, repair, or a modern upgrade to a programmable model for better efficiency and comfort in your home.

Mold in ductwork is a serious concern in our humid climate, as it can circulate spores and affect your family's health. We conduct thorough inspections using specialized tools to identify moisture sources and mold growth. Our service includes professional duct cleaning, addressing the root cause (like leaks or condensation), and recommending solutions like UV air purifiers or improved dehumidification to prevent recurrence.

Given our local humidity and frequent system use, we recommend bi-annual maintenance: a tune-up before summer and another before winter. This includes cleaning coils and drain lines to prevent mold-friendly clogs, checking refrigerant levels, calibrating thermostats, and inspecting ductwork for leaks or moisture. This proactive care improves efficiency, prevents major breakdowns, and safeguards your indoor air quality.
