The Charleston29402 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Breaker trips every time the system starts
Loud banging on start-up (compressor slugging)
Yellow or orange burner flame instead of steady blue
Thermostat reading several degrees off from reality
No cool air, or air that is barely cooler than the room
Pilot light or hot surface igniter failing repeatedly
Heating and air conditioning service built around Charleston
Long humid cooling seasons with coastal salt exposure that shortens condenser life without regular maintenance. Across the 29402 area that translates into a steady stream of failed capacitors, clogged filters, dying blower motors and refrigerant leaks — most of which we can diagnose and repair in one visit.
In the 29402 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.

Charleston29402 HVAC questions, answered
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
How quickly can a technician get to Charleston?
For the 29402 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.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Charleston, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
What does a new system cost in Charleston?
A complete residential replacement in the 29402 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.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
How often should I change my filter in 29402?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Charleston with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
