HVAC Repair Nashville TN | Call R R S Heating and AC Service

This is a very common issue here, often caused by a clogged condensate drain line. Nashville's high humidity means your AC produces a lot of condensation. Over time, algae and mold can block the drain, causing water to back up. We can quickly clear the blockage, flush the line, and often install a safety switch to prevent future water damage.

This usually points to reduced efficiency, and a dirty evaporator coil is a frequent culprit. Dust, pet dander, and pollen circulating in your home can coat the coil, insulating it and preventing it from absorbing heat properly. Our thorough coil cleaning service restores airflow and efficiency, helping your unit cool your home effectively without overworking.

We recommend a professional tune-up at least once a year, ideally before the peak cooling season. Our maintenance visit includes checking and clearing the condensate drain, inspecting and cleaning the evaporator coil, checking refrigerant levels, and ensuring all components are working correctly. This proactive care is the best way to improve efficiency, prevent breakdowns, and extend the life of your system in our climate.
