Emergency HVAC Repair in Lexington, TN 38351 - Smith Heating & Cooling

A dirty evaporator coil often means your system is pulling in dusty air from your ducts. Our professional air duct cleaning removes that built-up dust and debris at the source. This prevents it from re-coating the coil after a repair, allowing your HVAC system to absorb heat more efficiently, run cooler, and lower your energy bills. It's a key step in maintaining a clean, efficient system.

Common signs here in Lexington include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound. Our technicians use specialized tools to locate the exact leak point. We then repair or replace the faulty component, evacuate the system to remove moisture and air, and recharge it with the correct, EPA-approved amount of refrigerant to restore cooling performance and efficiency.

It's often a combination. A repair, like fixing a refrigerant leak or cleaning the evaporator coil, addresses the immediate mechanical issue. However, if your ducts are clogged with years of dust, that clean system will struggle to push air through your Lexington home. We typically assess both. A repair gets it running correctly, and duct cleaning ensures the improved airflow reaches every room, giving you the full benefit of the fix.
