Starn Heating and Air Conditioning has been handling residential and commercial HVAC work in Goose Creek since 2008. For more than 18 years, we have been the team local homeowners, landlords, property managers, and business owners call when the heating or cooling system needs attention. We're proud to be the HVAC company this community calls first.
Our locally owned and operated HVAC technicians live and work in this area. When you call, you reach someone who knows Goose Creek, knows the climate, and knows what it takes to keep a home or building comfortable through a long South Carolina summer or a cool winter stretch.
Experienced HVAC technicians. Code-compliant work. Professional service.
Whether you need a same-day repair, a full system replacement, or a seasonal tune-up, call (854) 296-6595 for a quote.
Comfort problems don't wait, and neither do we, which is why we keep a full range of HVAC services ready for residential and commercial customers across Berkeley County.
We handle AC repair and service, heating repair, heat pump service, full system installation and replacement, thermostat and smart-control upgrades, ductwork repair and sealing, indoor air quality improvements, and seasonal maintenance. Whether you own a single-family home, manage a rental portfolio, or run a commercial space, we have the experience to get the job done right.
Trusted by local homeowners and property managers for their heating and cooling, we bring the same level of care to every call, from a quick diagnostic to a complete system overhaul.
When your AC stops cooling, blows warm air, or quits running altogether, we diagnose the problem and fix it. A service visit covers refrigerant leak diagnosis, condenser and compressor inspection, airflow troubleshooting, and a full check of the system to find what went wrong and why. We'll get the job done and the system running.
No heat in the house is a problem we take seriously. We repair air handlers, blower assemblies, and furnace components when your heating system stops responding or fails to keep up. The focus here is repair and getting the system back online. Heat pump heating is covered in more detail further down the page, but whatever type of heating system you have, we can service it.
Heat pumps are the dominant system in the South Carolina coastal climate, handling both cooling and heating in one unit. When a heat pump stops cooling in summer or loses its heating capacity in winter, we diagnose and repair the issue. A service call covers refrigerant levels, reversing valve function, coil condition, and overall system performance. We'll take care of the system from here.
When a system is too old to repair cost-effectively, or when a building needs a new installation from scratch, we manage the full process. We assess the space, recommend the right equipment, and handle the installation with code-compliant HVAC work from start to finish. A new heat pump or central AC system is a significant investment, and we make sure the job is done properly.
Leaky or damaged ductwork drives up energy costs and creates uneven temperatures from room to room. We inspect, repair, and seal duct systems to restore proper airflow and improve efficiency. If some rooms feel stuffy or never quite reach the set temperature, the duct system is often the place to start.
A thermostat that does not respond accurately, or an older model that cannot communicate with a newer system, can undercut the performance of even a well-maintained unit. We install, replace, and configure thermostats and smart controls, including zoning setups that let different areas of the building run at different settings.
Stale air, dust buildup, and persistent odors are often signs of a filtration system that is not keeping up. We install air filtration upgrades and air purifiers that work with your existing HVAC system to improve what your household or building is breathing. Whole-home dehumidification, which makes a significant difference in this region, gets its own section below.
A maintenance visit before the cooling season starts is one of the most cost-effective things you can do for an HVAC system in the Lowcountry. We clean evaporator coils, check refrigerant levels, inspect electrical connections, test system controls, and flag anything that looks like it may cause trouble before the heat arrives. We make the repair and leave the home tidy.
Getting your comfort problem handled starts with a quick call, and for many homes in the area, a mini-split is the right answer. Ductless systems work especially well for sunrooms, additions, older homes without existing ductwork, and spaces where running new ducts is not practical.
We install, repair, and service mini-split systems for both residential and commercial customers. A ductless setup gives you zoning flexibility, quiet operation, and efficient performance without the cost or disruption of a full duct installation. If you are weighing a mini-split against other options, we can walk you through the comparison on the call.
The Lowcountry climate is defined by long, hot summers, persistent humidity, and mild winters that rarely push into hard-freeze territory. That combination shapes which HVAC services matter most here. Calling an HVAC company doesn't have to be stressful, and when you call us, you get honest recommendations on repair versus replacement, never an upsell.
Goose Creek and the surrounding Berkeley County area deal with high ambient humidity for most of the year. A standard air conditioner removes some moisture as it runs, but it cannot keep up when outdoor humidity is consistently high. A whole-home dehumidification system integrates directly with your HVAC equipment and manages moisture levels independently of whether the AC is actively cooling.
The difference is noticeable. Clammy air, musty odors, and elevated mold risk all trace back to humidity that an AC alone cannot control. We assess your current system, recommend the right capacity for your space, and handle the full installation. For most homes in this area, it is one of the most impactful comfort upgrades available.
Heat pumps are the system of choice across the South Carolina coast because they handle both cooling and mild-winter heating from a single unit. When temperatures stay above freezing most of the winter, a heat pump is more efficient than a gas furnace and eliminates the need for two separate systems.
We install new heat pump systems for homeowners replacing aging equipment and for properties moving away from older setups. The installation process covers equipment selection, proper sizing for the space, and code-compliant HVAC work through completion. We walk you through what to expect before we start and leave the site clean when we finish.
A long cooling season puts serious hours on a central AC system. When a unit reaches the end of its useful life, replacing it with a high-efficiency model pays back in lower utility bills, better comfort, and improved humidity management throughout the home.
The replacement process starts with a proper load calculation to size the new system correctly for your home. Oversized units short-cycle and leave humidity behind. Undersized units run constantly and still fall short. We size, select, and install the right equipment for the space, and we explain the options clearly before any work begins.
When the system goes down in the middle of a South Carolina heat wave, or when the heat stops working on a cold night, waiting is not an option. We offer same-day availability and respond to emergency calls for both no-cool and no-heat situations.
We protect your floors and finishes while we work, and we treat your home or building with the same care we would want in our own. When you call, you reach someone who can dispatch a qualified HVAC technician to the address, not a recording.
Local crew. Real technician on the phone. Quick to respond.
Call (854) 296-6595 any time you need emergency HVAC service.
We work across both sides of the market. On the residential side, that means homeowners, landlords, and property managers who need reliable service across one property or many. Rental properties and multi-unit buildings get the same quality of work as owner-occupied homes, and we understand the scheduling pressures that come with managing tenants.
On the commercial side, we service offices, retail spaces, and small commercial buildings that need their systems maintained and running without extended downtime. Commercial HVAC work involves larger equipment, more complex controls, and tighter timelines. Our team handles code-compliant HVAC work across both settings, and preventive maintenance plans keep commercial systems performing between service calls.
We built this business around HVAC work like this, and we have been doing it across the Charleston metro and Berkeley County for over 18 years.
Our primary service area is Goose Creek, and we also serve customers in Hanahan, Ladson, Summerville, North Charleston, Moncks Corner, Jedburg, Sangaree, and Wando. If you are nearby and not sure whether we cover your address, call and ask. We will tell you straight.
What a repair or replacement costs depends on the type of system, the scope of the work, the equipment involved, and the condition of what is already in place. We do not publish flat rates because no two jobs are identical, and a number pulled from a general range rarely reflects the actual situation.
What we do instead is give you a clear, honest quote before work begins. The call takes a few minutes. We ask about the system, the symptoms, and the property. From there we can give you a realistic picture of what the job involves and what it will cost.
Qualified technicians. Code-compliant work. Fair rates.

The South Carolina cooling season is long and puts serious hours on HVAC equipment. A spring tune-up catches small problems before the heat arrives, when a breakdown is most disruptive and technician demand is highest. A visit covers coil cleaning, refrigerant level checks, airflow verification, and thermostat calibration. Staying ahead of maintenance also extends equipment life, which matters when a system runs hard for eight or nine months a year.
The Goose Creek area deals with high ambient humidity for most of the year, and a standard air conditioner cannot keep up with it on its own. A whole-home dehumidifier integrates with your existing HVAC system and manages moisture levels independently of whether the AC is actively cooling. The result is air that actually feels comfortable rather than clammy, and it reduces the conditions that encourage mold growth inside the home.
Heat pumps handle both heating and cooling from a single system, and they run efficiently in the mild South Carolina winters without the cost of gas heat. The South holds the large majority of heat-pump homes in the country for exactly this reason. A properly sized heat pump handles the long cooling season and provides reliable heating when temperatures drop, making it the most practical system for most homes in this climate.
If a system is approaching or past 12 to 15 years of age, requires frequent repairs, or is running inefficiently through a long cooling season, replacement often makes more financial sense than continued repair. A high-efficiency replacement pays back faster in the South Carolina climate than in most parts of the country because of how many hours the system runs each year. We give you an honest comparison before recommending either path.
An AC that runs continuously without cooling the space is often dealing with a refrigerant issue, a dirty evaporator coil, restricted airflow, or a failing compressor. In some cases, the system is undersized for the space or is fighting humidity levels it cannot manage on its own. A diagnostic visit identifies the specific cause so the right repair is made rather than guessing at parts.
Unusual sounds are almost always a sign that something mechanical needs attention. Banging can indicate a loose or broken component inside the air handler or outdoor unit. Squealing often points to a worn belt or bearing. Rattling may mean debris in the system or a loose panel. Running a system that is making these sounds can turn a minor repair into a larger one, so it is worth calling us to take a look.
Uneven temperatures from room to room are usually caused by duct leaks, an undersized or improperly zoned system, blocked vents, or airflow restrictions somewhere in the distribution system. In some cases, the issue is a room that was added without accounting for the additional load. We diagnose the cause rather than just adjusting the thermostat, and we address it at the source.
The technician inspects the system, runs diagnostics, and identifies the root cause of the problem before recommending a course of action. For installations and replacements, we perform a load calculation to size the new equipment correctly for the space. We explain what we found and what we recommend before any work is approved, and we do not add scope without discussing it with you first.
Additional charges can come up if the technician opens the system and finds a secondary problem that was not visible during the initial assessment. When that happens, we stop and explain the new finding before proceeding. We do not add charges for work that was not discussed and approved. A clear estimate before work begins is part of how we operate on every job.
Older systems sometimes have installation or configuration issues that do not meet current code requirements. When we identify a code issue during a repair or replacement, we explain it to you before doing anything about it. Work performed by our qualified HVAC technicians is done to current code standards, and we handle the necessary corrections as part of the job rather than leaving them for later.
We have been in this community since 2008, and the business has grown because we do the work right and treat customers fairly. When you call, you reach a local person who knows the area. When the technician shows up, it is someone who takes the work seriously.
We're proud to be the HVAC company this community calls first, and we back that up with honest recommendations on repair versus replacement and code-compliant HVAC work on every job. We do not push unnecessary equipment or upsell services you do not need. We tell you what we found, what it will take to fix it, and what it will cost.

| Service Type | What It Covers | Best Suited For | Good to Know |
|---|---|---|---|
| Heat Pump Repair and Service | full system diagnostics, air handler and outdoor unit, short-cycling and efficiency issues, seasonal tune-ups | heat pump owners dealing with a system that heats or cools poorly or cycles on and off | A heat pump that short-cycles is often responding to a refrigerant, airflow, or sensor issue that gets worse if left alone through a full season. |
| Full System Installation and ReplacementMost Popular | residential and commercial installs, honest repair-versus-replacement assessment, correct sizing for the home or building, upfront pricing before work begins | homeowners and property managers whose system is aging, failing repeatedly, or no longer cost-effective to repair | A correctly sized replacement system runs more efficiently and breaks down less often than an oversized or undersized unit, so proper load calculation matters before any equipment is ordered. |
| Seasonal Maintenance and Tune-Ups | full system inspection and cleaning, evaporator coil cleaning, airflow and refrigerant check, thermostat calibration | homeowners who want to avoid breakdowns and keep the system running efficiently through the season | We recommend a spring AC tune-up before heavy heat arrives and a fall check before any heating demand. Preventive maintenance is the most cost-effective thing you can do for a hard-working system. |
| Emergency HVAC Service | same-day and evening availability, no-cool and no-heat response, weekend availability, quick dispatch | any home or business with a system that has stopped working and cannot wait for a standard appointment | We are available every day from 5:30 AM to 9:00 PM. When you call, you reach a local person who can get a qualified technician dispatched to your address. |
| Thermostat and Smart-Control Installation | programmable and smart thermostat replacement, zoning and room-by-room control, system compatibility check, setup and calibration | homeowners who want better comfort control or whose thermostat is unresponsive or outdated | A smart thermostat or zoning upgrade is one of the lower-cost improvements that can make a noticeable difference in both comfort and monthly energy use. |
| Ductwork Repair and Sealing | duct inspection and leak diagnosis, sealing and repair, airflow restoration, hot and cold spot correction | homes with uneven temperatures, high energy bills, or rooms that never get comfortable | Leaking ductwork can quietly waste a significant portion of conditioned air before it ever reaches the living space. Sealing it is one of the most practical efficiency upgrades available. |
| Heating and Furnace Repair | heat pump and furnace repair, airflow and blower issues, uneven temperatures, emergency heating service | any home or building that has lost heat or is heating unevenly | Heat pumps are the dominant heating technology in the Lowcountry, and we service them every day alongside the furnaces still in use across the area. |
| Whole-Home Dehumidification and Humidity Control | whole-home dehumidifier installation, integration with existing HVAC, humidity level assessment, mold and comfort improvement | Lowcountry homeowners dealing with heavy indoor humidity even when the AC is running | Coastal South Carolina humidity can make indoor air feel uncomfortable even at the right temperature. A whole-home dehumidifier addresses the moisture at the source rather than masking it. |
| High-Efficiency Central AC Replacement | aging system assessment, high-efficiency equipment selection, correct sizing for the home, full installation and startup | homeowners with a system approaching end of life that is driving up energy bills or breaking down repeatedly | A long South Carolina cooling season means an inefficient older system costs more here than in most parts of the country. A replacement pays for itself faster in this climate. |
| Indoor Air Quality and Air Filtration | air filtration system installation, air purifiers and air scrubbers, allergen and dust reduction, integration with existing HVAC | households dealing with dust, allergens, or air quality concerns, especially in homes where systems run hard year-round | In a region where HVAC systems run nearly continuously, the air handler circulates whatever is in the ductwork. A filtration upgrade works with the system already in place. |
| Heat Pump Installation | new heat pump sizing and selection, full installation and setup, single system for heating and cooling, efficient performance in mild winters | homeowners replacing an older system or building a new addition who want one efficient system for both seasons | The South holds the large majority of heat pump homes in the country for good reason. In the Lowcountry climate, a heat pump runs efficiently through the long cooling season and handles mild winters without the cost of gas heat. |
| AC Repair and Service | diagnose and repair all makes and models, condenser and compressor issues, refrigerant leak diagnosis, same-day availability | homeowners or tenants with a system that is not cooling or not running | Catching a small refrigerant or airflow problem early almost always costs less than waiting until the system quits in peak heat. |
How do I know if I should repair or replace my system?
We look at the age of the equipment, the cost of the repair relative to the system value, and how often it has needed attention recently. As a general guide, if a repair costs more than half the price of a replacement and the system is over ten years old, replacement usually makes more financial sense. We give you an honest read on both options and let you decide. We do not push equipment when a repair is the right call.
What are the signs that my AC or heat pump needs attention now rather than later?
Warm air blowing on a cooling call, weak airflow from the vents, a system that starts and stops in short cycles, unusual banging or squealing sounds, and a sudden spike in energy bills are all signs worth acting on quickly. In a South Carolina summer, a struggling system tends to deteriorate fast. Call us, describe what you are seeing, and we will let you know how urgent the situation is.
How often should I schedule maintenance or a tune-up?
Twice a year is the standard recommendation: a spring AC tune-up before the heavy heat arrives and a fall system check before any heating demand kicks in. In the Lowcountry, where cooling season is long and systems run hard, staying on a regular maintenance schedule is one of the most practical ways to avoid a breakdown at the worst possible time.
Transparent Upfront Pricing
We give you a clear quote before any work begins, and we do not add charges for work that was not discussed and approved. If something unexpected comes up during the job, we explain it and get your approval before moving forward.
What does a seasonal tune-up actually cover?
A tune-up visit includes a full system inspection, evaporator coil cleaning, airflow check, refrigerant level review, thermostat calibration, and an honest assessment of anything that needs attention. If the system is in good shape, we will tell you. If something needs work, we explain it clearly and give you a quote before anything is done.
Why is one room in my home always hotter or colder than the rest?
Uneven temperatures usually point to a ductwork problem, an airflow restriction, or a system that was not sized correctly for the home. Leaking or disconnected ducts can starve certain rooms of conditioned air while others get too much. We inspect the duct system and the equipment to find the source and fix it rather than just adjusting the thermostat and hoping for the best.
How do ductwork leaks affect my energy bills?
Leaking ducts can waste a significant portion of the conditioned air your system produces before it ever reaches the living space. That means the system runs longer to hit the thermostat setpoint, which drives up energy costs and adds wear to the equipment. Sealing the duct system is one of the more practical efficiency improvements available in an older home.
Same-Day and Emergency Availability
We are available every day from 5:30 AM to 9:00 PM, including evenings and weekends. When your system goes down in the middle of a South Carolina summer, we respond quickly and show up ready to work.
What causes a system to short-cycle, and is it serious?
Short-cycling means the system turns on and off in rapid succession rather than running a full cooling or heating cycle. It is often caused by a refrigerant issue, an oversized system, a dirty coil, or a failing component. It puts extra wear on the compressor and should be diagnosed before it leads to a larger repair. Call us and we will get a technician out to check it.
Do I need to be home when the technician arrives?
For most service and repair calls, yes, an adult should be present to give access to the equipment and to review what the technician finds before any work is approved. For commercial properties where a facilities contact can provide access, we can work with whatever arrangement makes sense for the site. Just let us know the setup when you call.
Work Performed by Qualified HVAC Technicians
Every job, from a routine tune-up to a full system replacement, is handled by qualified HVAC technicians who take code-compliant work seriously and treat your home with care.
How does your pricing and estimate process work?
We give you a clear estimate before any work begins. If a technician opens a system and finds something that changes the scope, we explain it and provide an updated quote before proceeding. There are no charges added at the end for work that was not discussed and approved. You know what the job costs before we start.
What should I know about whole-home dehumidification in the Goose Creek area?
Coastal South Carolina humidity is one of the more common comfort complaints we hear, even from homeowners whose AC is working correctly. A standard central AC system removes some moisture as it cools, but in a climate this humid it often is not enough. A whole-home dehumidifier integrates with the existing HVAC system and pulls excess moisture out of the air at the source. We assess your current humidity levels, recommend the right equipment for your home, and handle the full installation.
Is a heat pump a good choice for a home in the Berkeley County area?
Heat pumps are well suited to the Lowcountry climate. They handle both heating and cooling from a single system, run efficiently through mild winters without the cost of gas heat, and are built for long cooling seasons. The South has the highest concentration of heat pump homes in the country, and Berkeley County is no exception. We size the system to your home, walk you through the equipment options, and handle the full installation and setup.
Call (854) 296-6595 and we will give you a straight answer on what your system needs and what it will cost.
