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.

Why North Charleston Homeowners Trust Us

Florence HVAC treats this community like our own backyard, because it is. We show up when we say we will, we diagnose before we quote, and we put real numbers on both repair and replacement so you can decide with facts instead of pressure. Our technicians are seasoned on everything from 20-year-old furnaces to inverter heat pumps, our trucks carry the parts that actually fail, and our work is checked in every mode before we go. It's the reason so much of our local work comes from referrals.

Your HVAC Questions Answered

Two things decide it: the system's age and what actually broke. Equipment younger than about 10 years is almost always worth repairing. Once it's past 15 years, or if the compressor or heat exchanger goes, replacement usually makes more financial sense, particularly with the efficiency improvements of new equipment. Our technicians will price both options honestly and leave the decision to you.
Most repairs fall between $150 and $650 depending on the part and system type, while full system replacements typically run from around $5,000 to $12,000 installed, depending on size and efficiency. Every job starts with a diagnostic and a written, upfront quote. The price you approve is the price you pay, with no surprise line items.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit focuses on cooling: cleaning the coils, verifying the refrigerant charge, testing the capacitor, and measuring airflow. The fall visit covers heating: cleaning the burners, checking combustion, and testing every safety control. Keeping up with both visits adds years to your equipment, helps prevent breakdowns during the worst weather of the year, and usually pays for itself in energy savings.
Check the thermostat mode and batteries, the filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has built up on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (843) 268-6987. We'll get a technician moving your way right away.
Every major brand, 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 calls for them.
Yes. Mini-splits are a great fit for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the room it serves, place the indoor and outdoor units carefully, and take care of the line set, condensate drainage, and electrical connections correctly. If central equipment is the better fit, we'll say so.
In most cases, the same day. No-heat and no-cooling calls take priority over scheduled tune-ups, and we'll tell you an honest arrival time as soon as you call (843) 268-6987. Once our technician arrives, the common failure parts are already on the truck, so the majority of problems get fixed without a second trip.
We do both. Most calls start as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from every major brand. When repair no longer makes sense, we manage the full replacement, from the load calculation and hauling off the old unit to installation and testing in every mode. Whichever way it goes, you'll see clear pricing for each option before anything happens.
