Features that set our AC services apart
Experienced local technicians
Our team lives and works in Charleston, so we understand how local building styles and coastal air affect your cooling needs. Every technician undergoes continuous training on the latest AC technologies, with specific expertise in systems that perform well in high-humidity environments.
Comprehensive diagnostics
We don’t just guess at problems. Our team uses professional testing equipment to check refrigerant levels, measure airflow, test electrical components, and identify the true source of issues. This precision means we fix the actual problem, not just the symptoms.
Quality equipment and parts
We install American Standard and Rheem systems, selected specifically for their reliability in Charleston’s climate. When making repairs, we use manufacturer-approved replacement parts that maintain your system’s efficiency and warranty.
Same-day emergency service
AC problems don’t wait for convenient times. Our team provides emergency service when you need it most, including weekends and holidays. No one should suffer through Charleston heat when their AC fails.
Transparent pricing
You’ll always know what you’re paying before we start work. No surprise charges or hidden fees—just honest pricing from a company that values long-term relationships over quick profits.
Warning signs you need
AC service
Strange noises
New grinding, squealing, or banging sounds indicate mechanical problems that typically worsen over time. A clicking sound when starting up often signals electrical issues, while a constant humming that never stops could mean a frozen compressor.
Inconsistent cooling
If some rooms stay warmer than others or your system runs constantly but struggles to maintain temperature, you likely have airflow issues or an undersized system.
Rising energy bills
If your bills have jumped without corresponding use changes, your system is working harder than it should. This happens when components fail or you need maintenance.
Poor humidity control
Excessive indoor humidity means your AC isn’t properly removing moisture from the air, which can lead to mold growth and comfort issues.
Short cycling
If your system turns on and off frequently without completing full cooling cycles, it’s struggling with internal issues that waste energy and reduce cooling effectiveness.
The right AC service saves you money
We’ve helped families cut their summer energy bills by nearly 25% simply by repairing duct leaks and performing proper maintenance
Benefits of professional AC services
Charleston’s humidity creates unique challenges for AC systems. Beyond just controlling temperature, your AC needs to effectively manage moisture levels to prevent mold growth and maintain healthy air quality. Our technicians specifically address these local climate issues, helping you avoid that clammy feeling that comes with poorly functioning systems.
Many Charleston homes struggle with inconsistent cooling between rooms, especially in older buildings. We’ve helped families in historic homes solve temperature differences of up to 10 degrees between floors by properly sizing equipment and addressing airflow issues.
AC installation
When it’s time for a new system, proper installation makes all the difference. Our team helps you select the right size and efficiency level for your Charleston home, considering your specific needs and budget. We handle everything from removing old equipment to setting up your new system, including any necessary ductwork modifications. Installation typically takes 1-2 days, and we minimize disruption to your home throughout the process. Every installation includes system testing and optimization to ensure peak performance from day one.
AC replacement
If your current system is over 10 years old or breaking down frequently, replacement is the smart move for your home and wallet. Not only do newer units work better, they can reduce costs 20-30%. We handle the entire replacement process, from helping you take advantage of available rebates and financing options to properly disposing of your old system in an environmentally responsible way.
AC repair
When your system breaks down, quick, effective repairs restore comfort to your home. Our technicians diagnose and fix issues with all brands and models, carrying commonly needed parts in our service vehicles to complete most repairs in a single visit.
AC maintenance
Regular maintenance prevents breakdowns and extends system life. Our comprehensive tune-ups include cleaning coils, checking refrigerant levels, inspecting electrical components, lubricating moving parts, and testing overall performance.
Maintenance should be performed twice yearly—in spring before cooling season and fall before heating season. These visits typically take about an hour but save you money by improving efficiency by up to 15% and catching small issues before they lead to expensive failures.
Join our Comfort Club maintenance program for priority scheduling, discounted repairs, and automatic visit scheduling. Members experience fewer breakdowns and longer system lifespans, with the average properly maintained AC lasting 5-7 years longer than neglected systems.

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.
