Why Us
When summer heat meets AC problems in Charleston
When your air conditioner fails during Charleston’s intense summer heat, it quickly becomes more than an inconvenience—it’s an emergency that affects your entire household. Those sweltering days with 90+ temperatures and high humidity demand a functioning cooling system, and delays in repairs can make your home unbearable.
Reliable AC repair built for Charleston’s climate
Same-day emergency service
Breakdowns in 90-plus heat are urgent, so we prioritize emergency calls and show up ready to fix most problems on the first visit.
Comprehensive diagnostics
Our testing equipment pinpoints exactly what’s failing, so you get a targeted repair instead of expensive guesswork.
Fully stocked trucks
Our technicians carry common parts, refrigerant, and the specialized tools most Charleston repairs need — which is how we finish so many fixes same-day.
All major brands
We repair every major manufacturer, and as a Mitsubishi Diamond Contractor we go deep on ductless and heat pump systems.
Refrigerant Leak Detection
We find even small leaks that cause weak cooling and high bills, so the repair holds instead of failing again in a month.
Electrical repairs
Failed capacitors, burned contactors, and faulty wiring are common AC-failure culprits in this climate, and our licensed team fixes them safely.
“Mr. Brian arrived on time, identified the problem, ordered the part, and my A/C issue was solved. I will always choose Blanton’s. Thank you to all the Blanton’s team!”

the best HVAC services
At Blanton & Sons, we’ve been providing fast, reliable AC repairs for Charleston families since 1998, getting systems back online quickly even during the busiest times of the season.
Signs you need AC repair now
Warm air from the vents
If the system runs but blows room-temperature air, you may have a refrigerant leak, a failing compressor, or an airflow problem that needs a pro.
Strange noises
Grinding, squealing, banging, or clicking points to a mechanical issue that gets more expensive the longer it runs.
Short-cycling
An AC that turns on and off constantly is usually fighting an electrical fault, a thermostat issue, or low refrigerant — and wasting energy doing it.
Ice on the unit
Ice on indoor or outdoor components signals an airflow or refrigerant problem that can permanently damage the compressor if ignored.
Humidity the AC can’t beat
If your home stays clammy while the system runs, you may have a sizing problem, duct leaks, or failing equipment.
Why Charleston homeowners trust our AC repair
Fast comfort restoration. Most repairs are finished the same day you call, so you’re not waiting days for parts or a technician while the house bakes.
Honest pricing. We fix what’s actually broken instead of upselling. When a repair would cost more than half of an aging system’s value, we’ll tell you straight — and walk through AC replacement only if it genuinely saves you money.
Longer system life. Quality parts and proper repairs keep your AC running efficiently for years, pushing back the day you need a full replacement.
Fewer surprise breakdowns. We address the underlying cause, not just the symptom, so you’re less likely to lose cooling during the worst heat of the summer.

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!
Drew M.
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.
S. H.
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!!

Frequently Asked Questions
How fast can you get to my AC repair in Charleston?
Most AC repair calls in Charleston are handled same-day. We prioritize by urgency, and because our trucks are stocked with common parts and refrigerant, we fix the majority of problems on the first visit. Call (843) 256-6454.
Should I repair my AC or replace it?
A good rule of thumb: if a repair costs more than half of what your current system is worth and the unit is past 10–12 years, replacement usually wins. We give you an honest read either way and never push a replacement that doesn’t save you money. See AC replacement in Charleston.
Do you repair all AC brands?
Yes — we service every major manufacturer, and as a Mitsubishi Diamond Contractor we have particular depth on ductless mini-splits and heat pumps that are common in Charleston homes.
Why does my AC struggle with humidity even when it’s running?
In Charleston’s climate, an AC that runs but leaves the house clammy often has an oversizing issue, duct leaks, or a component problem. We diagnose the moisture issue, not just the temperature — pairing repairs with indoor air quality and dehumidification when it helps.
