Hanahan homes and businesses run on heating and cooling equipment that works hard through a long, humid season. When something goes wrong, or when a system is simply due for replacement, the job needs to be scoped correctly before anyone shows up. We cover everything from a single failed component on a system that is otherwise sound to pulling out old equipment and installing a new one from scratch.
Call (854) 296-6595 any day from 5:30 AM to 8:30 PM and someone who knows the trade picks up.
The town draws a mix of residential homes and smaller commercial properties, and the work reflects that. A homeowner dealing with an AC that stopped cooling overnight has different needs than a landlord trying to get a rental back in service before a new tenant arrives. We handle both, and the process is the same either way: scope the job on the call, confirm the price before scheduling, and carry out the work at the property. We serve Hanahan and the surrounding area across Berkeley County.
Some spaces were never meant to be cooled by a duct system, and forcing ductwork into them rarely works well. A sunroom addition, a converted garage, a bonus room above the main living area, or a space that sits at the far end of a long duct run are all candidates for a ductless mini-split. These systems handle both heating and cooling from a single unit, which makes them practical in a region where the heat pump is already the dominant technology.
Installation involves mounting the air handler inside the space, running a refrigerant line set to the outdoor unit, and wiring the controls. There is no ductwork to design or route, which keeps the job cleaner and faster than a full central system installation. If a room in the property is consistently uncomfortable regardless of what the thermostat says, a mini-split is often a more direct solution than trying to rebalance the existing duct system.
We also service and repair mini-splits that are already installed. A unit that is not cooling or heating the way it should gets the same diagnostic approach as any other system: check the refrigerant charge, inspect the line set, assess the air handler and the outdoor unit, and work from what the equipment actually shows.
A system that runs for hours without bringing the space to the set temperature is telling you something. The fault might be a refrigerant charge that has dropped, a coil that is fouled enough to block heat transfer, or a duct system leaking conditioned air into an unconditioned space. It might also be a sizing problem, where the equipment was never right for the load the property puts on it. The diagnostic separates those causes and points to the right correction.
In this part of the country, gas furnaces are uncommon, but heat pumps with electric auxiliary heat are standard. When auxiliary heat stops engaging or a heat pump cycles on and off without completing a heating cycle, the fault is often in the control board, the reversing valve, or the sensor that tells the system what mode to run in. We trace the fault to the component rather than quoting parts before the diagnosis is done.
The air handler is the part of the system most homeowners never think about until it fails. A blower motor that is drawing too much current, a capacitor that is on its way out, or a coil that has accumulated enough debris to restrict airflow all show up as performance problems before they become full breakdowns. A musty or burning smell when the system starts is often the first sign. Catching it at that stage is less disruptive than waiting for the system to stop running entirely.
A full central AC installation covers the outdoor condenser, the air handler, the refrigerant line set, the ductwork connections, and the thermostat. When the existing duct system is staying in place, we assess it before the new equipment goes in. Ductwork that leaks or restricts airflow limits what a new system can do regardless of its efficiency rating. If sealing or repair is needed, that gets factored into the scope before the installation is scheduled.
A burning smell at startup often points to dust burning off a heating element that has not run in months, but it can also indicate a motor that is overheating or wiring that is beginning to fail at the equipment. A musty smell is usually biological growth on the evaporator coil or inside the duct system, which is common in a climate where the air handler handles significant moisture. Neither one should be ignored, and both are diagnosable on a standard service visit.
On properties with electric air handlers and heat pump systems, the heat exchanger equivalent is the heating coil inside the air handler. A coil that is cracked, corroded, or fouled affects both heating performance and air quality. If indoor air quality is a concern or the system has been producing unusual smells on the heating cycle, an inspection of the air-side components is a reasonable starting point.
Getting your comfort problem handled starts with a quick call. When a system stops working entirely, that call gets treated as urgent. The person who answers can scope an emergency visit on the phone, ask the right questions about the equipment and the symptoms, and tell you what the visit covers before anything is booked. We take calls every day from 5:30 AM to 8:30 PM.
For rental properties and commercial spaces where tenants or customers need to stay comfortable, the scheduling conversation includes what the property requires. A business that cannot close for a repair and a rental unit that needs to be habitable before a move-in date both factor into how the visit gets set up. That is worked out on the call, not after the technician is already on site.
You hear what the repair involves before you agree to it. That applies whether the call is about an emergency or a planned visit.
Seasonal maintenance is not just a filter swap. A proper tune-up before the cooling season covers refrigerant pressure, coil condition, electrical connections at the equipment, blower performance, and thermostat calibration. Each of those checks catches a different category of fault. A refrigerant charge that is slightly low reduces efficiency and puts extra load on the compressor. A coil that is beginning to foul reduces heat transfer before it causes a visible problem.
For heat pumps, which handle both heating and cooling in this region, a pre-season check also covers the reversing valve and the defrost cycle. A heat pump that cannot switch modes correctly will underperform on one side of the year even if it seems fine on the other.
After the visit, you get clear notes on what was checked and what was found. That record is useful the next time the system needs attention, and it gives the property owner a current picture of where the equipment stands.
Replacing a system with the same size that came out is not the same as replacing it with the right size. The load a property puts on its HVAC system depends on the square footage, the insulation, the window area, and how the space is laid out. Any of those can change over time. An addition, a window replacement, or an attic insulation upgrade all affect what the new equipment needs to handle.
Load calculations done properly on a replacement account for the actual condition of the property. A system that is undersized runs constantly and never fully satisfies the space. One that is oversized short-cycles, which wears the equipment faster and leaves humidity levels higher than they should be. Getting the sizing right at the point of replacement is what determines how the system performs for the years after installation.
This matters more in a climate with a long, demanding cooling season. A system that is matched to the property runs more efficiently and puts less wear on its components than one that is fighting a mismatch from day one. How a job in Hanahan usually runs is walked through on the page listing our HVAC services.
The price for any HVAC job reflects what the fault turns out to be, what has to be accessed to correct it, and whether a repair or a replacement is the answer that makes sense for the equipment. A refrigerant leak that is straightforward to locate and seal is a different scope than one that requires recovering the charge, isolating the leak in a line set that runs through a finished wall, and recharging the system.
For a replacement, the quote accounts for the equipment selected, the scope of the installation, and whether the existing ductwork and electrical connections at the equipment are in condition to support the new system. If duct sealing or repair is part of what the property needs, that is discussed before the work is scheduled, not after.
Older equipment is assessed on its own merits before a replacement is recommended. Some systems have a repair that is cost-effective and extends their useful life. Others have reached a point where continued service costs more than replacement over any reasonable timeframe. The diagnostic produces the information needed to make that comparison, and the price is confirmed before anything is scheduled.

We cover Hanahan and the communities around it in Berkeley County, including Goose Creek, North Charleston, Charleston, Ladson, and Sangaree. Whether the property is a single-family home, a rental unit, or a small commercial building, the work is handled locally and scoped before the visit is set up.
If you are searching for HVAC repair, maintenance, or installation in this part of the county and you are not sure whether your address falls within the service area, call (854) 296-6595 and we will confirm it on the call.
Ask what the repair costs relative to what a replacement would cost, whether the repaired component is likely to cause further faults in related parts, and what the system's overall condition looks like. A straight answer to those questions gives you the information you need to decide whether the repair makes sense or whether the money is better applied toward replacement.
Yes. A property with several systems, whether a multi-unit residential building or a commercial space with multiple zones, can be assessed and serviced as a single job.
Call (854) 296-6595 and describe the property, the number of units, and what each one needs so the visit can be scoped and priced as a whole.
Heat pumps are the standard choice across this region because they handle heating and cooling in a single unit and perform efficiently through mild winters and long cooling seasons. For most properties in Hanahan, a heat pump is the practical answer. A ductless mini-split is a better fit for spaces that cannot be served by a central duct system, such as an addition or a converted room. The right answer depends on the property, and that is worked out during the scoping call and the visit.
If the system is making unusual noises, producing a burning smell, or tripping the breaker repeatedly, switch it off and call (854) 296-6595.
If it is running but underperforming, leaving it on is usually fine while waiting for a scheduled visit. When you call, describe what the system is doing and we will advise on whether it should stay on or off.
Call (854) 296-6595 and describe the system and the symptoms.
The person who answers can scope the visit on the phone and tell you what the diagnostic covers and what it costs before anything is booked. For a rental unit where a tenant is waiting on a repair, that information helps you make the scheduling decision quickly. We work around the access situation at the property, and that is part of the conversation when the visit is set up.
We handle both residential and commercial HVAC work in Hanahan and the surrounding area. Small commercial buildings, office spaces, and retail properties are part of the regular workload, and the process is the same as for a home: the job is scoped on the call, the price is confirmed before anything is scheduled, and the work is carried out at the property.
Call (854) 296-6595 to talk through what a commercial visit covers.
Yes. A clogged filter restricts airflow enough to cause a range of symptoms including reduced cooling, ice on the coil, and the system running longer than it should. Replacing a dirty filter takes a few minutes and sometimes resolves the issue without a service call.
If the system is still not performing correctly after the filter is changed, call (854) 296-6595 and describe what you are seeing.
A system that is aging, running less efficiently, or showing early signs of trouble is easier to deal with on a schedule you choose than on the one a breakdown forces.
Call (854) 296-6595 any day from 5:30 AM to 8:30 PM to get a quote, book a tune-up, or talk through a replacement before the season puts pressure on the timeline.
We take heating and cooling work in these nearby communities as well: North Charleston, Charleston, Ladson.
