Immaculate Heating and Air Conditioning has served Gastonia and Gaston County since 1998, and the work we do today is the same work we have always done: show up, diagnose the problem honestly, and get the system running right. We handle the full range of heating and cooling work for homes and businesses across the area, from AC repair and furnace service to full system replacement, heat pump installation, ductwork repair, thermostat upgrades, indoor air quality, seasonal maintenance, and emergency calls when the system goes down without warning. Family-owned. Locally rooted. Comfort is our business.
We cover the complete scope of residential and commercial HVAC work. Whether it is a straightforward repair or a full system overhaul, our team handles it with code-compliant HVAC work on every job, so you know the result meets the standard it should.
Leave the heating and cooling to us.
Not every HVAC company works the same way, and not every contractor understands what this part of North Carolina actually demands from a heating and cooling system. Gastonia sits in the western Piedmont, where summers run hot and humid and winters deliver genuine cold snaps that push equipment hard. Both ends of the calendar matter here, and the services below reflect that reality.
When a system is aging, breaking down repeatedly, or simply not keeping up with the load, replacement is often the smarter call. We assess the full picture first: the age of the equipment, the repair history, the sizing relative to your space, and where efficiency gains are realistic. A properly sized, properly installed system handles both the sustained cooling demand of a Gastonia summer and the heating load that arrives when temperatures drop into the teens. Our technicians walk you through the options, handle the installation, and make sure the work meets code before we leave. If rooms in your home run warmer or cooler than they should, that is often a sizing or airflow issue we can address at the same time.
The Piedmont climate is one of the better fits for heat pump performance in the country. Winters here are cold enough to need reliable heating but mild enough that a heat pump operates efficiently through most of the season. Summers are long and warm, and a heat pump handles cooling the same way a conventional air conditioner does. We install both ducted heat pumps for homes with existing ductwork and ductless mini-split systems for additions, older homes, or spaces that need independent zone control. We protect your floors and finishes while we work, and we leave the space cleaner than we found it.
Humidity in Gastonia is not just a summer problem. It lingers into the shoulder seasons and works against your comfort even when temperatures are manageable. A portable dehumidifier handles one room. A whole-home dehumidifier integrates with your HVAC system and manages moisture across the entire living space, reducing the load on your air conditioner and improving the air quality your family breathes every day. Excess moisture also feeds mold growth and makes allergens worse, so this is not a luxury upgrade for most homes in this area. We find the fault. We make the repair. We restore the comfort.
Your time matters, so we keep the HVAC job on schedule and the communication clear from the first call to the final walkthrough. When something goes wrong with your system, the symptoms usually tell the story: the AC is not cooling, the furnace is not producing heat, the system is making noise it should not, a unit is leaking or freezing up, or the air coming out of the vents is the wrong temperature entirely. A service call starts with a thorough diagnosis so we know what is actually causing the problem before any work begins. We carry parts for the most common repairs, and we give you a straight answer on whether a repair makes sense or whether replacement is the better path. Prompt response, even for last-minute comfort calls, is how we operate.
Seasonal tune-ups matter more in a climate that runs both a heavy cooling season and a real heating season. A pre-summer AC tune-up and a pre-winter furnace or heat pump check catch small problems before they become emergency calls. We inspect the equipment, clean the components that need it, check refrigerant levels, test controls, and confirm the system is ready for the season ahead.
You shouldn't have to chase a contractor for answers, especially when a comfort problem is affecting your customers, your tenants, or your employees. We work with small businesses, offices, retail spaces, multi-unit residential buildings, and rental properties across the Gastonia area. Landlords and property managers rely on us for fast scheduling, honest assessments, and clear communication so they can keep their tenants comfortable and their properties in good standing.
The name on our trucks is our own, and we protect it. That means showing up when we say we will, doing the work right the first time, and being available when a commercial system goes down and the call is urgent. We handle commercial repair, replacement, and installation, and we keep the work code-compliant from start to finish. Let us handle the install and the permits.
What a repair or replacement costs depends on several factors: the type of system, its age, the scope of the work, and the parts involved. A refrigerant recharge is a different conversation than a full system replacement, and a heat pump installation in a home with existing ductwork is different from a ductless mini-split in a room addition. The only reliable way to get an accurate number is a call and an on-site look at the equipment. We give you a clear picture of what the job involves and what it will cost before any work begins. Call for a quote and we will get you scheduled.
We are based in Gastonia and have been working throughout Gaston County and the surrounding communities for more than two decades. In addition to Gastonia, we regularly serve customers in Belmont, Mount Holly, Cramerton, Dallas, Lowell, Stanley, Kings Mountain, and Bessemer City. If you are in the broader Charlotte-area region and are not sure whether we cover your neighborhood, give us a call. Chances are we do.
Common warning signs include the system running constantly without reaching the set temperature, unusual noises during operation, ice forming on the outdoor unit outside of a brief defrost cycle, and a noticeable drop in heating or cooling output. If your heat pump is more than 12 to 15 years old and showing any of these symptoms, it is worth having a technician assess whether repair or replacement makes more sense.
Short-cycling, where the furnace starts and stops repeatedly without completing a full heating cycle, is often caused by a clogged filter restricting airflow, an overheating heat exchanger, or a faulty flame sensor. Cold air from the vents usually points to an ignition failure or a problem with the heat exchanger itself. Both situations call for a proper diagnosis before any repair is attempted, since the underlying cause matters for both safety and long-term equipment performance.
A burning smell at the start of the heating season is often dust burning off the heat exchanger and may clear on its own after the first run. A persistent burning smell, or one that smells like melting plastic or electrical components, warrants a service call right away. A musty smell typically points to mold or moisture in the ductwork or on the evaporator coil, which is a common issue in Gastonia's humid climate and something we can address directly.
The most common causes are low refrigerant from a leak, a dirty or frozen evaporator coil, a failing capacitor, or restricted airflow from a clogged filter or blocked vents. Any of these can cause the system to run continuously without reaching the set temperature, which also drives up energy use. A technician will run through a systematic diagnosis to find the actual cause rather than guessing at a fix.
An undersized system runs almost constantly during peak weather without ever fully catching up to the thermostat setting. An aging system shows up as higher energy bills for the same output, more frequent repair calls, unusual noises, and uneven temperatures across the home. If your equipment is pushing 15 years or more and you are calling for repairs more than once a season, a replacement assessment is worth having.
Keep the thermostat set to a moderate, safe temperature rather than cranking it to an extreme in hopes of forcing the system to respond. If there is a burning smell or you suspect a gas issue, leave the home and call the appropriate emergency line before calling us. Otherwise, stay comfortable, keep pets and children away from the equipment, and have a general sense of when the problem started and what the system was doing when it failed.
Yes. For installations and replacements that require permits and inspections under North Carolina code, we handle that process. Code-compliant work on every job is the standard we hold ourselves to, and that includes making sure the paperwork side is handled correctly. Let us handle the install and the permits.
A repair makes sense when the equipment is relatively young, the fault is isolated, and the cost of the fix is reasonable relative to the remaining useful life of the system. Replacement makes more sense when the equipment is old, has a history of repeated failures, or is no longer efficient enough to justify keeping. We give you an honest assessment of both paths and the cost of each so you can make the decision that fits your situation.
Banging or clanking usually points to a loose or broken component inside the air handler or furnace. Squealing often indicates a worn blower motor belt or bearing. Rattling can mean debris in the system or a loose panel. Any noise that is new, persistent, or getting louder warrants a service call, since running a system with a mechanical fault typically makes the underlying problem worse and more expensive to fix.
When the evaporator coil freezes, airflow through the system drops sharply and the AC loses most of its ability to cool. The coil freezes when refrigerant is low, airflow is restricted by a dirty filter or blocked return, or the system is running in conditions it was not designed for. If you notice ice on the indoor unit or the refrigerant lines, turn the system to fan-only mode and call us. Running the compressor with a frozen coil can cause compressor damage.
Older homes in Gaston County often have ductwork that has developed leaks over time, insulation that has settled or degraded, and equipment that was sized for different conditions than the home has today. Conditioned air escaping through leaky duct joints before it reaches the living space is one of the most common causes of uneven temperatures. We inspect and seal ductwork and can assess whether the equipment sizing is contributing to the problem.
The technician will walk you through what was done, confirm the system is operating correctly, and answer any questions before leaving. We clean up the work area and protect your floors and finishes while we work. If the job involved a new installation or replacement, we will make sure you understand how to operate the new equipment and thermostat before we go.
A whole-home dehumidifier installs inline with your existing air handler and ductwork, pulling excess moisture from the air as it circulates through the system. Unlike a portable unit that handles one room, it treats the entire home continuously. In Gastonia's climate, where humidity stays elevated through much of the year, this reduces the load on your air conditioner, improves indoor air quality, and makes the home feel more comfortable at the same thermostat setting.
Yes. We install programmable thermostats, smart thermostats including Nest and Ecobee, and standard replacement units. If your current thermostat is unresponsive, reading the wrong temperature, or not communicating correctly with the system, that is also a diagnostic service call we handle. A thermostat upgrade is one of the more straightforward ways to improve performance from an existing HVAC system.
Immaculate Heating and Air Conditioning has been a working part of this community since 1998. When you call, you reach someone who knows Gastonia, knows the climate here, and can get your service scheduled without delay. We are locally owned and personally accountable for every job that goes out under our name.
If your system is down today, do not wait it out. A no-heat or no-cool situation in the middle of a Gaston County winter or summer is a real problem, and we treat it that way. Call (980) 463-9789 for a quote and let us get your system back where it belongs. We find the fault. We make the repair. We restore the comfort.

| HVAC Service | What It Covers | When You Need It | What to Keep in Mind |
|---|---|---|---|
| Indoor Air Quality and Air Filtration |
| households concerned about mold spores, pollen, dust, or airborne particles in a humid climate | In Gaston County's humid summers, upgrading filtration at the system level addresses air quality far more effectively than portable units. |
| Heat Pump Repair and Service |
| homes already running a heat pump that needs diagnosis, repair, or a seasonal check | North Carolina's mild winters make heat pumps a strong fit here; keeping one well-serviced pays off year-round. |
| AC Repair and Service |
| homeowners or businesses with an AC that has stopped cooling or is underperforming | Same-day response is available for urgent no-cool situations during peak summer heat. |
| Thermostat and Smart-Control Installation |
| anyone looking to improve system control, reduce energy use, or replace an unresponsive thermostat | A thermostat upgrade is one of the more straightforward ways to get better performance from an existing system. |
| Furnace and AC System Replacement |
| homes with aging equipment that struggles through summer heat or winter cold snaps | Replacing both sides at the same time often makes more sense than patching an old system that keeps failing on alternating seasons. |
| Seasonal Maintenance and Tune-Ups |
| homeowners who want to catch small problems before they become expensive failures mid-season | A spring AC tune-up and a fall furnace tune-up are the simplest ways to protect both sides of the system before peak demand arrives. |
| Ductwork Repair and Sealing |
| homes with uneven temperatures, high energy bills, or rooms that never reach the right setpoint | Leaky ducts are one of the most common causes of uneven comfort; sealing them often improves the whole system's performance. |
| Full System Installation and Replacement |
| homeowners or property managers replacing aging equipment or upgrading an undersized system | We size equipment for the actual space rather than defaulting to whatever was there before, which affects both comfort and efficiency. |
| Emergency HVAC Service |
| any situation where the system has gone completely down and waiting is not an option | We come prepared to diagnose and repair on the same visit whenever possible so you are not waiting an extra day for parts to be sourced. |
| Heat Pump Installation |
| homeowners upgrading from a furnace-and-AC setup or adding heating and cooling to a new space | Gastonia's mild winters mean a heat pump runs in efficient heating mode for most of the cold season, making it a strong long-term value here. |
| Whole-Home Dehumidification and Humidity Control |
| homes in Gaston County where high indoor humidity makes the air feel warmer than the thermostat reads | Sustained high indoor humidity contributes to mold growth and wood damage; addressing it at the system level is more effective than room-by-room portable units. |
| Heating and Furnace Repair |
| any home or building where the furnace is short-cycling, blowing cold air, or not responding | Emergency and same-day furnace repair are available when the heat goes out overnight or on a weekend. |
How do I know whether I need a repair or a full system replacement?
The honest answer depends on three things: the age of the equipment, how often it has needed repairs recently, and whether it is keeping up with the heating or cooling load in your space. A system that is 15 or more years old and has needed multiple repairs in the past couple of seasons is often a better candidate for replacement than another patch job. We give you a straightforward assessment after the diagnosis rather than defaulting to replacement when a repair is the right call.
What are the signs that my AC or furnace may be failing?
For an AC, watch for the system running constantly without reaching the setpoint, warm air from the vents, ice buildup on the outdoor unit, or a sudden spike in your energy bill. For a furnace, short-cycling, cold air from the vents, unusual smells, or a system that simply will not start are all signs something is wrong. Any of those symptoms is worth a diagnostic call before the problem gets worse.
How often should I schedule a maintenance tune-up?
Once a year for each side of the system is the standard. A spring tune-up gets the AC ready before Gaston County summer heat arrives, and a fall tune-up prepares the furnace or heat pump before the first cold snap. Skipping a season is not catastrophic, but it does mean small issues go undetected longer, which tends to turn into larger repair bills.
Same-Day and Emergency Availability
When the system goes down completely, we treat it as the urgent situation it is. Same-day response is available for no-heat and no-cool calls, and we are available 6 AM to 9:30 PM including weekends.
Is the HVAC work permitted and inspected to code?
Yes. We perform code-compliant HVAC work on every job. For installations and replacements that require a permit, we handle that process and the work is done to meet local code requirements. That protects you as the homeowner and ensures the equipment operates safely and correctly.
Why is one room in my house hotter or colder than the rest?
Uneven temperatures are usually caused by one of a few things: leaky or undersized ductwork that is losing conditioned air before it reaches that room, an airflow imbalance in the system, or equipment that is not sized correctly for the whole house. Ductwork inspection and sealing often resolves the problem, though we diagnose the specific cause before recommending a fix.
What do strange noises from my HVAC unit usually mean?
A banging or clanking sound often points to a loose or broken component inside the unit. A high-pitched squealing can indicate a blower motor bearing issue. A rattling sound at startup sometimes means debris in the system or a loose panel. None of these should be ignored, since what starts as a minor mechanical issue can escalate quickly. Calling for a diagnostic visit early is almost always cheaper than waiting.
Code-Compliant Work on Every Job
Every installation and repair we perform meets local code requirements. For jobs that require a permit, we handle that process so you are covered from start to finish.
Can a dirty filter or coil actually hurt my system's performance?
Significantly. A clogged filter restricts airflow, which forces the system to work harder to move the same amount of air. Over time that extra strain shortens the life of the blower motor and compressor. A dirty evaporator or condenser coil reduces the system's ability to transfer heat, which shows up as reduced cooling capacity and higher energy use. Changing filters regularly and scheduling annual coil cleaning are two of the simplest things a homeowner can do to protect the equipment.
What does a smart thermostat installation actually involve?
We remove the existing thermostat, verify the wiring is compatible with the new unit, install and configure the new thermostat, and test the communication between it and the HVAC equipment. For most homes, the process is straightforward. If the existing wiring does not include a common wire, which some older systems lack, we address that as part of the installation. You leave with a working, properly configured system, not just a new device on the wall.
Clean and Respectful Workmanship
We protect your floors and finishes while we work and clean up completely before we leave. Your home or building should look the same when we are done, minus the HVAC problem.
How does whole-home dehumidification work with my existing HVAC system?
A whole-home dehumidifier installs inline with your existing air handler and ductwork. As air circulates through the system, the dehumidifier pulls moisture out before the air is distributed through the house. The result is lower indoor humidity across every room, not just where a portable unit happens to be running. In a humid climate like Gaston County's, that makes a real difference in how comfortable the air feels even at the same thermostat setting.
Do I need to be home when the technician arrives?
For most service calls, yes. The technician needs access to the equipment, and you will want to be present to hear the diagnosis, ask questions, and approve any work before it starts. If your situation requires leaving access without being home, call us ahead of time and we can talk through how to handle it for your specific job.
How do estimates and pricing work before the job starts?
After the technician diagnoses the system and explains what is needed, we give you a clear picture of the cost covering parts and labor before any work begins. If the scope changes once we are into the job, we talk to you before we proceed. There are no charges for work you did not agree to upfront.
Call (980) 463-9789 to schedule service or request a quote, and we will give you a straight answer on what your job involves and what it will cost.
