Heating and air conditioning service built around Charleston
Nobody in Charleston wants to spend a day waiting on a technician with a four-hour window. We quote a 2-4 hours target response time for this ZIP and hold crews locally so that number is realistic.
In the 29424 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Charleston29424 HVAC questions, answered
Why is my system short cycling?
Short cycling in Charleston most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in South Carolina, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Charleston we see algae and dust clogging drain lines constantly during April through October. It is a fast fix but ignoring it ends in ceiling damage.
Are your technicians licensed and insured?
Every technician dispatched into Charleston is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
How quickly can a technician get to Charleston?
For the 29424 service area our target response time is 2-4 hours from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
What does a new system cost in Charleston?
A complete residential replacement in the 29424 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
