Common AC Problems We Repair in the Columbia Area

South Carolina's long cooling season stretches from April well into October, putting significant stress on AC equipment across communities like Lexington, Irmo, Chapin, and throughout Richland and Lexington counties. High humidity alone accelerates wear on components that homeowners in drier climates rarely worry about.



Our technicians commonly repair refrigerant leaks that reduce cooling capacity and can damage the compressor over time, failed compressors that leave a system running without producing cold air, frozen evaporator coils caused by restricted airflow or low refrigerant, faulty capacitors and contactors that prevent the outdoor unit from starting, dirty condenser coils that cause overheating and shutdown, thermostat malfunctions causing short-cycling or uneven temperatures, and clogged condensate drain lines that are especially common in humid Midlands summers.

How Do You Know If Your AC Needs Repair?

Your system often gives clear warning signs before it fails completely. You may need air conditioning repair if your unit is blowing warm or barely cool air, making unusual grinding or squealing noises, cycling on and off more frequently than normal, producing musty or burning odors, or causing a noticeable spike in your energy bill without a change in usage. Scheduling repair early, before a minor issue becomes a major one, is almost always the more cost-effective path.

Our Air Conditioning Repair Process

Shealy HVAC keeps the repair process straightforward and transparent. Here is what to expect:


1. Schedule a diagnostic appointment by calling (803) 796-1923 or submitting a request through our contact page.

2. System inspection by a licensed technician who checks refrigerant levels, electrical components, airflow, and coil condition.

3. Clear diagnosis and honest recommendation so you understand exactly what failed before any work begins.

4. Repair and testing with the technician verifying the system is cycling correctly, cooling efficiently, and draining properly before leaving.

5. Follow-up guidance on maintenance steps that may help extend the life of your equipment.

 

Should You Repair or Replace Your AC Unit?

If a system is under 10 years old and the repair cost is modest relative to the unit's value, air conditioning repair typically makes financial sense. If the system is 15 or more years old, has required multiple repairs in recent seasons, or uses refrigerant types being phased out, replacement may offer better long-term value. Our technicians provide an honest assessment either way, and we carry free estimates on new and replacement units so you can compare options without pressure.
