AC replacement services in Ravenel: Upgrade your cooling comfort


What our AC replacement service includes

Precise system sizing for your home’s needs 

We don’t just swap out equipment and leave. Our comprehensive AC replacement starts with a thorough assessment of your home’s specific cooling needs. We measure your space accurately, evaluate insulation levels, check window placement, and consider local climate factors to determine the perfect system size for your home. This careful sizing process prevents the common problems of oversized units (short cycling and poor humidity control) or undersized systems (inability to cool adequately on hot days).

Quality equipment built for coastal environments 

We install American Standard and Rheem systems built to withstand Ravenel’s challenging coastal environment. These units feature corrosion-resistant components that stand up to salt air, variable-speed technology for superior humidity control, and comprehensive warranty protection. Most systems we install offer SEER ratings between 16-20, providing significant efficiency improvements over older 10-12 SEER units typically found in homes built before 2010.

Complete ductwork evaluation and optimization 

Your ductwork gets special attention during replacement too. We evaluate existing ducts, seal leaky connections, add insulation where needed, and ensure proper sizing for balanced airflow throughout your home. This comprehensive approach addresses the entire system, not just the equipment itself.

Smart control integration 

We also integrate smart thermostats that learn your preferences, adjust automatically to save energy, and allow remote control via smartphone. These advanced controls typically save an additional 10-15% on cooling costs while giving you unprecedented control over your comfort.

“Blanton’s didn’t just replace our AC unit like the other companies wanted to do. They found serious duct leaks in our attic that had been wasting nearly 30% of our cooling. Their complete system approach has made every room comfortable for the first time while actually lowering our power bills.”

— Michael, Ravenel Homeowner

What Our Customers Say

Overall amazing experience with these guys. We did major duct work and new AC unit which they installed the next day. Guys were here for 12.5 hours working very hard to get the job finished but due to part issue bc of manufacturer they had to come back. They came back the next day with the right part and finished the job. Kyle D especially worked extremely hard – working through rain and high heat to finish the work. Give that man a raise!

Will Jackson and Jacob Nettles from Blanton & Sons just finished installing a new heating and ac system at my home. They were prompt, diligent, efficient, and took the time to explain everything to me. They even came back after completing the project to make sure everything was working properly. In addition to demonstrating exceptional competence at their craft, Will and Jacob were extremely polite and friendly. They showed great respect for my property and cleaned up the work area very well. I will be recommending them to everyone.

We had a new AC system installed by Wallace and team. It was a big job and was well coordinated. The complex work AS20 seer was worked on for over ten hours to full operation. The clean up was thorough and all techs were courteous and helpful. Great job everyone – thank you!!


How do I know it’s time to replace my AC instead of repairing it again?

A few signals together usually make the case: the unit is past 10–15 years old, repairs are becoming frequent or expensive, your power bills keep climbing, or it can no longer keep the house comfortable in peak heat. When a major component like the compressor fails on an aging system, replacement is almost always the better investment than the repair.

How much does it cost to replace an AC system in Charleston?

It varies with home size, the efficiency level you choose, and any ductwork that needs attention, so the honest answer comes from an in-home assessment. As a reference, full system replacements in this market commonly fall in the several-thousand-dollar range and up.

Every replacement includes a $0 dispatch fee to assess, a written price upfront, removal of the old system, and financing — including 0% for 12 months for qualified buyers. Call (843) 256-6454.

Will a new, higher-efficiency AC really lower my energy bills?

Usually yes, and the difference can be significant if you’re replacing a system that’s 12+ years old. Efficiency is measured in SEER2; older units often sit far below current models, so a new system can meaningfully cut cooling costs over a long Charleston summer. We’ll show the efficiency options and a rough payback so you can weigh upfront cost against monthly savings.

Should I replace my outdoor and indoor units together?

Generally, yes. Pairing a new outdoor condenser with an old indoor air handler (or vice versa) often means a mismatch that undercuts efficiency, strains both components, and can complicate warranty coverage. Replacing them as a matched system delivers the performance and lifespan the equipment is rated for.

Can I replace my AC and add whole-home air quality or filtration at the same time?

Yes, and it’s an efficient time to do it — the system is already open and the technicians are on site. Many homeowners pair a replacement with a dehumidifier or air purification upgrade for our humid climate. Mention it when you schedule and we’ll include the options in one combined quote.
