Professional HVAC Service in Florence

Florence homeowners don't call an HVAC company on a good day. They call when the AC dies in a heat wave, when the furnace clicks but never lights, when one bedroom stays ice cold no matter what the thermostat says. Charleston HVAC built its local reputation on those calls: answering fast, arriving with stocked trucks, and fixing the actual fault instead of selling a new system. From quick capacitor swaps to full heat pump conversions, our technicians handle every job with upfront pricing and no pressure, and we treat your home like it belongs to a neighbor, because around here, it does.

Complete Heating & Cooling Services for Florence Properties

Heating and cooling around here covers a lot of ground: older gas furnaces on the older streets, newer heat pumps in recent construction, ductless mini-splits in additions and converted garages, and rooftop units on commercial buildings. Our team works on every one of those systems. Our technicians have years in the field, and we've learned how the weather here, the age of local homes, and local code affect the way a system runs over time.

On the residential side, we take care of everything from quick fixes, like a failed capacitor, a burned contactor, a dirty flame sensor, or a seized blower motor, to tracking down refrigerant leaks, complete system replacements, and ductless additions. We size every new system with a proper load calculation instead of a rule of thumb, so you get even temperatures and reasonable utility bills instead of a unit that short-cycles itself to an early death. Our seasonal tune-ups clean coils, verify refrigerant charge, test safety controls, and check static pressure, still the most reliable way to extend equipment life.

For commercial property owners and managers nearby, we service the rooftop units, split systems, and dedicated ventilation equipment that restaurants, shops, offices, and apartment buildings depend on. We understand that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, stock common parts on the truck, and schedule work around your operating hours whenever we can.

Fast HVAC Response in Florence

If your heat or air quits, how fast help shows up matters more than anything else. For that reason, we keep our schedule flexible across the area and put a real person on the phone. Urgent calls usually get a technician within a day, and we prioritize a failed furnace in a cold snap or a dead AC in the heat ahead of routine work.

Here's what we see most often when something breaks at home: warm air from the AC, a condenser that hums but won't start, a furnace that ignites and shuts off, a breaker that keeps tripping, an evaporator coil that has iced over, a condensate drain backed up into the furnace cabinet, or a thermostat that has gone blank. Most of them come down to parts already on our trucks: capacitors, contactors, igniters, flame sensors, universal control boards, and common fittings. You get the price before any work starts, with no surprises on the invoice.

If your AC has iced over, the most helpful thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and damage the compressor. If a furnace is short-cycling or you smell something burning, turn it off at the service switch and call (843) 268-6960. A few minutes of caution can head off a much larger repair.

Getting More Years From Your HVAC System in Florence

A little routine care makes all the difference between a system that runs for years and one that breaks down in the middle of a heat wave. Our advice for homeowners is a short list: a new filter every one to three months, two feet of clearance around the outdoor condenser, a gentle rinse each spring for the condenser coil, and a professional tune-up every spring and fall, so small issues get caught early.

The age of your equipment plays a big role. With regular service, a central air conditioner typically lasts 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts acting up, like rising energy bills, rooms that never reach the setpoint, or one repair after another, it's time to plan a replacement. A planned replacement is cheaper and is far less stressful than scrambling for a new system during the worst heat wave of summer.

Small problems don't stay minor when they're ignored. Take a weak capacitor: replacing it is a quick, inexpensive repair, but if it's ignored for a season, it can burn out the compressor, and just like that a minor fix becomes a full system replacement. That's why we encourage homeowners to save our number in their phone and call at the first sign of trouble. Catching it early saves time and money and spares you a miserable night.

Common HVAC Problems in Florence

Most local HVAC failures give warning signs before they happen. A breaker that trips every few days, a condenser that hums louder each month, rooms drifting further from the thermostat setting, a musty smell at startup. These are the early symptoms of failing capacitors, refrigerant leaks, dirty coils, and duct problems, and caught early they're an affordable repair. Ignored, they take out compressors and heat exchangers, the two most expensive parts in the system. We diagnose the cause, not just the symptom, so small problems stay small.

Local HVAC Experts

As a locally-operated HVAC company, we understand the unique challenges homeowners here face. From capacitors that quit in a heat wave to igniters that fail on the first cold night, our technicians know what to look for and how to fix it.

Why Florence Residents Choose Us

We answer quickly, arrive prepared, and fix the cause, not just the symptom, checking the airflow, charge, and electrical conditions that killed the failed part in the first place. Pricing is agreed up front and doesn't move. Whether it's a same-day AC repair or a planned system upgrade, the job is done right on the first visit.

HVAC FAQ for Local Residents

All major brands, including Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can source brand-specific components quickly when a repair requires them.
Start with the simple checks: confirm the thermostat is set to cool and has fresh batteries, look at the filter to see if it's clogged, and check the breakers for both the indoor and outdoor units. If none of that helps and the outdoor unit is humming without starting, or you see ice on the copper lines, shut the system off to protect the compressor. Then call (843) 268-6960 and we'll send a technician to your home as fast as we can.
It comes down to age and which part failed. Under about 10 years, most component failures are worth fixing. Past 15 years, or any time a compressor or heat exchanger fails, replacement is usually the smarter investment, especially given how much more efficient new equipment is. We give you both numbers straight and let you make the call. We'd rather earn your trust than sell you a system before you need one.
For a lot of homes, yes. Ductless mini-splits work especially well in room additions, converted garages, sunrooms, and older homes that never had ducts. Our approach starts with sizing each zone to the actual room, followed by thoughtful placement of the indoor and outdoor units and a clean install of the line set, condensate drainage, and electrical connections. If central air would be the better choice for your layout, we'll let you know.
Yes, and for most homeowners it's the smartest money you can spend on a system. Each spring and fall, a technician cleans the coils and burners, checks the refrigerant charge and combustion, tests capacitors and safety controls, and measures airflow from supply to return. Catching problems during a tune-up costs far less than a breakdown in the peak of summer, and the energy savings usually cover the cost of the visit.
Yes. We repair all major brands of air conditioners, furnaces, heat pumps, and ductless mini-splits. When a system is beyond saving, we handle the entire replacement: removing and disposing of the old equipment, installing a properly sized new system, and testing it in every mode. You get a clear quote for each option before deciding.
Fast. We cover the whole area with same-day appointments for most calls, and no-heat and no-AC calls get top priority. Our trucks are stocked with the most frequently needed parts, including capacitors, contactors, igniters, and motors, so most repairs are diagnosed and finished in a single visit. Call (843) 268-6960 and we'll give you an honest arrival window.
It depends on what's wrong. Most repairs come in between $150 and $650, depending on the failed part and the type of system. A full replacement generally costs around $5,000 to $12,000 installed, with size and efficiency making the difference. Before we begin, you'll get a clear quote based on the diagnostic, and that number doesn't change.
