Comfort problems don't wait, and neither do we, so we keep our service menu broad enough to handle whatever your system throws at you. Below is a look at the everyday HVAC work we handle for homes and commercial properties across the area.
AC not cooling, blowing warm air, or not turning on at all? We diagnose and repair all makes and models, including condenser and compressor issues, refrigerant leak diagnosis, and anything else keeping your system from doing its job. Same-day AC repair is available, and we offer seasonal tune-ups and maintenance inspections to keep things running before problems start.
When the heat goes out, we respond fast. Heat pumps are the dominant heating technology across South Carolina, and we service them every day. Furnace repair is available for homes that have one. We handle airflow problems, uneven temperatures, air handler and blower issues, and full system failures. Emergency heating repair is available when you need it most.
Heat pump not heating, not cooling, or cycling on and off? We troubleshoot the full system, from the air handler to the outdoor unit, and get it back in shape. We also offer heat pump tune-ups and seasonal maintenance to keep efficiency where it belongs.
When repair no longer makes sense, we handle full system installations and replacements for homes and commercial properties of all sizes. You get up-front pricing before any work begins, and honest repair-versus-replacement recommendations so you can make the right call for your budget.
Leaking or damaged ductwork quietly drives up energy bills and creates hot and cold spots throughout the home. We inspect, seal, and repair ductwork to restore proper airflow and get comfort back on track.
Thermostat not responding, or ready to upgrade to a smart control? We replace outdated units and set up programmable and smart thermostats, including zoning and comfort-control systems that let you manage temperatures room by room.
We install air filtration systems, air purifiers, and air scrubbers that work with your existing HVAC setup to reduce dust, allergens, and airborne contaminants. Cleaner air makes a real difference, especially in a region where systems run hard year-round.
Mini-split systems are a strong fit for additions, converted spaces, and buildings without existing ductwork. We handle mini-split repair, installation, and full replacement for both residential and commercial applications.
We'll take care of the system from here.
Calling an HVAC company doesn't have to be stressful, especially when your system goes down in the middle of a South Carolina summer. We offer same-day and emergency service for no-cool and no-heat situations, including evenings and weekends. When temperatures outside are climbing and your AC is not running, waiting days for a technician is not an option.
Trusted by local homeowners and property managers for their heating and cooling, we show up ready to work and give you a clear picture of what the repair involves before anything is approved. No surprises on the bill. No pressure to approve work you're not sure about.
Experienced HVAC technicians. Code-compliant work. Professional service.

Berkeley County sits in the South Carolina Lowcountry, where summers are long, hot, and relentlessly humid, and winters stay mild enough that a hard freeze is the exception rather than the rule. That climate shapes which HVAC services matter most here, and the three below come up more than any others.
Coastal South Carolina humidity is not just uncomfortable. It drives up cooling costs, encourages mold growth, and makes indoor air feel heavy even when the thermostat is set where you want it. A whole-home dehumidifier works alongside your existing HVAC system to pull excess moisture out of the air at the source, rather than just masking the problem. We assess your current humidity levels, recommend the right equipment for your home's size and layout, and handle the full installation and integration. The result is air that actually feels comfortable, not just cool.
Heat pumps are the right fit for the Lowcountry. They heat and cool from a single system, run efficiently in mild winters without the cost of gas heat, and handle the long South Carolina cooling season without skipping a beat. The South holds the large majority of heat-pump homes in the country for good reason. We size the system to your home, walk you through equipment options, and handle the full installation and setup so you're not left guessing about what you got or how it works.
An aging central AC system running through a long, intense cooling season costs more every year and breaks down more often as it gets older. If your system is approaching the end of its useful life, a high-efficiency replacement pays for itself faster here than in most parts of the country. We assess your current setup, give you an honest read on whether repair or replacement makes more sense, and install a new system sized correctly for your home. We'll get the job done and the system running.
Property managers, building owners, restaurant operators, retail tenants, and warehouse operators all have one thing in common: a system that goes down costs money fast. We provide commercial AC repair, commercial heating repair, rooftop unit service, and full commercial HVAC system installation and replacement across the area. Same-day availability extends to commercial accounts, and you get up-front pricing before work begins so there are no billing surprises.
Our locally owned and operated HVAC technicians handle commercial work with the same attention they bring to residential jobs. Whether you manage a single storefront or a multi-unit property, we keep your systems running and your tenants or customers comfortable.
Getting your comfort problem handled starts with a quick call, but the best time to call is before a problem develops. Preventive maintenance is the most cost-effective thing you can do for a system that works hard through a South Carolina cooling season.
We recommend a spring AC tune-up before the heavy heat arrives and a fall system check before any heating demand kicks in. A tune-up visit covers a full inspection, cleaning, airflow check, evaporator coil cleaning, and thermostat calibration. You get an honest assessment of what we find, including honest recommendations on repair versus replacement, never an upsell. If the system is in good shape, we'll tell you. If something needs attention, we'll explain it clearly and give you a quote before any work is done.
We built this business around HVAC work like this, and we have been doing it in Goose Creek since 2008. When you call, you reach a local person who knows the area and can answer your questions directly. When a technician shows up at your door, it is someone who works here, not a stranger passing through. We treat your home the way we'd want ours treated, and we protect your floors and finishes while we work. That personal accountability is what a locally owned business is built on, and it is what keeps customers calling us back.
We make the repair and leave the home tidy.
Goose Creek is our home base, and we serve the broader Charleston metro and Berkeley County region on a daily basis. Our service area includes:
If you are nearby and not sure whether we cover your area, call and ask. We will give you a straight answer.
Yes. We offer same-day availability and respond to emergency calls for both no-cool and no-heat situations, including evenings and weekends. When you call, you reach a local person who can get a qualified HVAC technician dispatched to your address. Call (854) 296-6595 and we will get someone out as quickly as possible.
We are available every day from 5:30 AM to 9:00 PM. That coverage is intentional in a climate where a system going down on a weekend afternoon or an early weekday morning is a real problem. Call (854) 296-6595 any time within those hours and we will get you taken care of.
Yes. We handle residential and commercial HVAC work across Goose Creek and the surrounding Berkeley County communities. Whether you own a single-family home, manage a rental portfolio, or operate a commercial space, we service all of it. Same-day availability extends to commercial accounts as well.
Check that the thermostat is set correctly and that the circuit breaker for the unit has not tripped. If the system still will not respond, call us at (854) 296-6595. Do not attempt to force a system to run if it is making unusual sounds or showing signs of a refrigerant or electrical issue. We will get a technician out to diagnose it properly.
Warm air blowing from the vents on a cooling call, weak or restricted airflow, a system that starts and stops in short cycles, or unusual banging, squealing, or rattling sounds all point to a problem that is worth addressing quickly. In the South Carolina summer heat, a struggling system tends to deteriorate fast. Call us and describe what you are seeing and we will let you know how urgent the situation is.
The technician will inspect the system, diagnose the specific problem, and walk you through what was found and what the repair involves before any work is approved. Depending on the call, a visit may include refrigerant level checks, coil inspection, airflow testing, thermostat calibration, or component-level diagnostics. You get a clear picture of the work and the cost before anything is done.
We give you a clear estimate before any work begins, and we do not add charges for work that was not discussed and approved. If a technician opens up a system and finds something that changes the scope, we will explain it and give you an updated quote before proceeding. There are no surprise charges at the end of the job.
It helps to know the type of system you have (heat pump, central AC, furnace, mini-split), the approximate age of the equipment if you know it, and a description of what the system is doing or not doing. If the system has been serviced before, any notes on prior repairs are useful. The more context you can give us on the call, the more accurately we can prepare for the visit.
For routine maintenance or a non-urgent repair, scheduling a few days ahead is generally sufficient. During peak cooling season in the Lowcountry, demand is higher and lead times can stretch. For urgent or emergency situations, we offer same-day availability. Call (854) 296-6595 and we will give you an honest timeline based on current availability.
Frequent breakdowns on an aging system are often a sign that the equipment has reached the end of its cost-effective repair life. We will give you an honest assessment of whether continued repair makes financial sense or whether a replacement would serve you better in the long run. We do not push unnecessary equipment, and we will lay out the comparison clearly so you can make the right call for your budget.
When your heating or cooling system needs attention, Starn Heating and Air Conditioning is ready to help. We offer same-day availability, transparent up-front pricing, and work performed by qualified HVAC technicians who stand behind what they do. Residential or commercial, routine maintenance or emergency repair, we handle it all across Goose Creek and the surrounding area.

If you have questions after looking it over, call us and we will walk you through it.
| 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.
