Trusted North Charleston HVAC Service
Comfort in North Charleston shouldn't be seasonal. Florence HVAC keeps local homes and businesses comfortable year-round with fast, professional heating and cooling service, from same-day AC repair to right-sized system replacements. We've worked in nearly every neighborhood in the area, which means we've seen how these systems fail locally and we arrive prepared, with capacitors, contactors, igniters, and motors already on the truck. Call (843) 268-6987 and we'll get the fix started.

Heating and Air Conditioning Service Across North Charleston
Heating and cooling around here covers a lot of ground: aging 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 code requirements affect the way equipment performs and fails.
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 refrigerant leak repair, full system change-outs, and ductless additions. We size every new system with a proper load calculation rather than guesswork, so you get even temperatures and sensible utility bills instead of a unit that short-cycles itself to an early death. Seasonal maintenance visits clean coils, verify refrigerant charge, test safety controls, and check static pressure, still the most reliable way to extend equipment life.
Local businesses receive the same care. An overheated storefront or a freezing office costs real money, so our commercial crews focus on getting to the cause quickly and keep common parts on board for rooftop units, split systems, and ventilation equipment. Property managers, restaurant owners, and retailers can ask us to work around their business hours whenever possible.
Fast HVAC Response in North Charleston
When your heat or air quits, how quickly help shows up matters more than anything else. That's why we keep our schedule flexible across the area and answer every call with a live person. Emergency calls typically see a technician within a day, and we treat no-heat and no-cool calls as top priority.
Common emergencies we handle include air conditioners blowing warm air, outdoor units that hum but won't start, furnaces that ignite and then shut down, breakers that trip whenever the system starts, frozen evaporator coils, clogged condensate drains backing up into the furnace cabinet, and thermostats that have simply given up. Our trucks carry the capacitors, contactors, igniters, flame sensors, universal control boards, and fittings needed to finish most repairs in a single visit. We provide upfront pricing every time, so you know exactly what the work will cost before we begin.
A few minutes of caution before we arrive can prevent a much bigger repair. A frozen air conditioner should be turned off at the thermostat with the fan set to "on", which lets the coil thaw safely. Running it frozen can flood the drain pan and damage the compressor. A short-cycling furnace, or any burning smell, means it's time to kill power at the furnace switch and call us right away.
Getting More Years From Your HVAC System in North Charleston
Many mid-season breakdowns start with maintenance that never happened, and the habits that prevent them are simple. Change your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and hose off the condenser coil once a year in spring. Then book a professional tune-up each spring and fall, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.
How old is your system? That number says a lot about what comes next. With regular service, most air conditioners make it to 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is beyond that point and is also showing rising bills, uneven temperatures, or frequent repairs, it's usually due for a planned replacement, which is almost always cheaper and easier on everyone than an emergency replacement in peak season.
The earlier you report a comfort problem, the cheaper it usually is. A weak capacitor is an easy, low-cost part to replace, yet the same part, neglected for a season, can take out the compressor and turn a simple fix into a full system replacement. Save our number in your contacts now so help is one call away the moment something sounds or feels wrong in your home. Early intervention saves time, money, and sleepless nights.
Typical Heating & Cooling Issues in North Charleston
Most local HVAC failures announce themselves before they happen. A breaker that trips more than once, 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 a quick visit. Ignored, they take out compressors and heat exchangers, the two most expensive parts in the system. We find the root cause instead of treating symptoms, so small problems stay small.
