Duck River Heating & Air is a local HVAC company serving homeowners and businesses across Columbia, TN and Maury County. Our team handles air conditioning repair, AC installation, furnace repair, heat pump service, ductless mini-split systems, ductwork, thermostat upgrades, and indoor air quality work for every type of home in Middle Tennessee. Summers along the Duck River get hot and humid, and winter nights can drop below freezing, so your heating and cooling system works hard all year. When your central air stops cooling, your furnace won't ignite, or your heat pump starts blowing cold air in January, we diagnose the real problem and fix it the right way. We work on gas furnaces, electric furnaces, split systems, packaged units, and high-efficiency SEER2 equipment from major brands like Trane, Carrier, Lennox, Goodman, Rheem, and Daikin. Our services cover refrigerant leak detection, capacitor and compressor issues, blower motor repair, frozen evaporator coils, clogged condensate lines, airflow problems, and short cycling. We also offer seasonal AC tune-ups and furnace maintenance to help lower energy bills, extend equipment life, and prevent surprise breakdowns. If your system is aging or inefficient, we help you choose a properly sized replacement based on your home's square footage, insulation, and ductwork. For better indoor air, we install air purifiers, whole-home dehumidifiers, UV lights, and upgraded filtration. We proudly serve Columbia, Spring Hill, Mount Pleasant, Culleoka, Santa Fe, Hampshire, Williamsport, and nearby Maury County communities.
