Qualified HVAC Repair in Chapin, SC 29036 - Carrillo Heating and Air

This is often a clogged condensate drain line, a very common issue in our humid Chapin climate. As your AC cools the air, it removes moisture that drains away through a line. Over time, algae and mold can block it, causing water to back up. We offer professional drain line cleaning and maintenance to clear the clog and prevent future leaks and potential water damage.

This could point to a faulty reversing valve, a key component that switches your system between heating and cooling. Issues are common during our seasonal shifts in Chapin. The valve may be stuck, failing, or have an electrical problem. Our technicians can diagnose the exact cause, perform repairs, or recommend a replacement to restore your system's proper function for year-round comfort.

Preventative maintenance is key. We recommend bi-annual tune-ups: one in spring before cooling season and one in fall before heating season. These visits include checking refrigerant levels, cleaning coils, inspecting electrical components, and crucially—clearing your condensate drain line and testing the reversing valve operation. This proactive care can catch small issues early, improve efficiency, and extend your system's life.
