Mark's Heating & Air: Certified HVAC Repair Serving Abbeville, SC 29620

Abbeville's humidity and airborne pollen can quickly coat your AC's evaporator coils, acting like insulation and forcing your system to work much harder. This leads to poor cooling and higher electric bills. Our team provides thorough coil cleaning as part of our maintenance service, restoring efficiency and extending your system's life to keep you comfortable all summer.

Yes, a clogged condensate drain line is a very frequent issue here, often caused by algae and mold growth in our humid climate. This can cause significant water damage. At Mark's Heating & Air, we clear the blockage with specialized tools, apply an algaecide treatment to prevent recurrence, and check the drain pan and safety switch to ensure your home stays dry and protected.

We recommend a bi-annual maintenance plan tailored for our local conditions. In the spring, we focus on your cooling system: cleaning those critical evaporator coils, flushing and treating the condensate drain line, and checking refrigerant levels. In the fall, we service your heating system. This proactive approach prevents most emergency repairs, improves efficiency, and gives you peace of mind.
