HVAC Repair Columbus OH | Call M & J Heating & Cooling Refrigeration

Columbus experiences significant humidity, especially in summer. Your AC's evaporator coil removes this moisture from the air, which then drains away via the condensate line. Over time, algae, mold, and mineral deposits from our local water can clog this line. A clog prevents drainage, leading to water damage, system shutoff, and potential mold growth. Our preventative maintenance service includes cleaning this vital line to keep your system running smoothly.

A frozen evaporator coil is often a symptom of restricted airflow or low refrigerant levels—common issues we see in Columbus homes. Dirty air filters, blocked return vents, or failing blower motors can cause it. When the coil freezes, your AC loses cooling power. Our technicians will safely thaw the coil, then diagnose and resolve the root cause, whether it's a simple filter change, a ductwork issue, or a refrigerant leak repair, to restore efficient cooling.

Absolutely. Many clogged drain lines and frozen coils are preventable with professional seasonal maintenance. Our comprehensive maintenance visit includes cleaning the condensate drain line and pan, checking refrigerant levels, cleaning coils, inspecting electrical components, and replacing your air filter. This proactive care improves efficiency, extends your system's lifespan, and helps avoid the inconvenient breakdowns that often happen during our hottest or coldest days.
