Immaculate Heating and Air Conditioning has served Gastonia and Gaston County since 1998, handling the full range of residential and commercial heating and cooling work that keeps homes comfortable and businesses running. Whether you need a same-day AC repair, a new furnace, a heat pump installation, or a seasonal tune-up, we show up ready to do the job right. Call for a quote today.
Family-owned. Locally rooted. Comfort is our business.
Whether it's a one-time repair or a full system replacement, we cover the complete scope of HVAC work for homes, rental properties, offices, and commercial spaces across the area. That means AC repair and service, heating and furnace repair, heat pump service, full system installation and replacement, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality solutions, and seasonal maintenance.
Homeowners count on us when the system goes down in the middle of a Carolina summer. Property managers and commercial operators count on us for reliable scheduling and prompt response, even for last-minute comfort calls. Whatever the situation, we come prepared to diagnose it, fix it, and get your system back to full performance.
Leave the heating and cooling to us.
When your air conditioner stops cooling, the problem could be a refrigerant leak, a failed capacitor, a compressor issue, or a restricted airflow problem. A qualified HVAC technician will run through a systematic diagnosis: checking refrigerant levels, testing electrical components on the low-voltage control side, inspecting the condenser and evaporator coils, and verifying airflow through the system.
We offer same-day AC repair for urgent situations. If your home is heating up fast and you need someone out quickly, call us and we will get a technician on the way.
A pre-season tune-up covers coil inspection and cleaning, refrigerant level verification, low-voltage control component checks, and a full airflow test. Getting this done before the summer heat arrives in Gaston County means your system is ready to handle the load when temperatures climb. Small issues caught in spring cost far less than an emergency repair in July.
A furnace that won't heat, short cycles, or blows cold air is telling you something is wrong. Common faults include ignition failures, heat exchanger issues, blower motor problems, and control board errors. Our technicians work on both gas and electric furnace systems, running through a thorough inspection on every service call to find the root cause rather than guessing at a fix.
Code-compliant HVAC work on every job means you can trust the repair is done safely and correctly. Same-day and emergency furnace repair are available when the heat goes out and waiting is not an option.
A fall furnace tune-up is the simplest way to protect your heating system before Gaston County winter arrives. We inspect the heat exchanger, test ignition, check the blower, verify the thermostat is communicating correctly, and look for any wear that could turn into a failure mid-season. Catching a cracked heat exchanger or a failing ignitor in October is a much better outcome than a no-heat call in January.
Seasonal maintenance is not just about avoiding breakdowns. It keeps the system running at its designed efficiency, which shows up in your energy bills over time.
Gastonia sits in a true four-season climate. Summers are hot and humid, winters are mild but real, and the seasonal humidity stays elevated for much of the year. That combination puts steady demand on both the heating and cooling sides of a home's HVAC system, and it explains why the three services below come up most often for local homeowners and property managers.
Aging equipment that struggles through a July heat wave or an unexpected cold snap is a sign the system has reached the end of its useful life. A full furnace and AC replacement addresses both sides at once, which often makes more sense than patching an old system that keeps failing. The process starts with an honest assessment of what you have, followed by equipment sizing for your specific space and a clear estimate before any work begins.
We handle the full installation from start to finish. Let us handle the install and the permits.
North Carolina sits in one of the strongest heat pump adoption zones in the country, and for good reason. The Gastonia area's mild winters mean a heat pump runs in efficient heating mode for the bulk of the cold season, without the sustained deep-cold conditions that push heat pump efficiency down. New heat pump installation includes proper sizing, refrigerant line set work, and thermostat configuration to get the most out of the system.
For spaces without existing ductwork, or for additions and outbuildings, ductless mini-split systems are a practical option we install and service as well. Heat pump repair and seasonal tune-ups are also available if you already have a heat pump that needs attention.
In a humid Carolina summer, the air can feel warmer than the thermostat reads because excess moisture is doing as much work on your comfort level as the temperature itself. A whole-home dehumidifier integrates directly with your existing HVAC system, pulling moisture out of the air across the entire house rather than just one room. The result is air that feels cooler at the same setpoint, less strain on the AC equipment, and better indoor air quality overall.
Humidity control also matters for the structure of the home. Sustained high indoor humidity contributes to mold growth, wood warping, and dust mite populations. Addressing it at the system level is a more effective solution than portable units in individual rooms.
Not every HVAC company works the same way, and the difference shows most clearly on an installation job. We start with a proper assessment of the space, load calculation, and an honest conversation about equipment options that fit the building and the budget. Equipment is sized for the actual space, not just swapped for whatever was there before.
The name on our trucks is our own, and we protect it. That means we protect your floors and finishes while we work, we clean up completely when the job is done, and we stand behind what we install. Whether it is a central air installation for a new home, a full HVAC replacement for a commercial property, or a system upgrade for a rental unit, you can call for a quote and we will give you a straight answer on what the job involves and what it will cost.
A thermostat upgrade is one of the more straightforward ways to get better performance out of an existing HVAC system. We install programmable thermostats, smart thermostats including Nest and Ecobee, and standard replacement units. If your thermostat is unresponsive, reading the wrong temperature, or not communicating with the system correctly, that is also a diagnostic service call we handle.
Leaky ductwork is one of the most common reasons a home heats or cools unevenly. When conditioned air escapes through gaps and unsealed joints before it reaches the living space, the system runs longer and works harder to hit the setpoint. We inspect ductwork, locate leaks, seal problem areas, and repair damaged sections. If you have rooms that never seem to reach the right temperature, ductwork is often part of the answer.
Whole-home air purifiers, UV air purifiers, HEPA filtration systems, and air scrubbers all integrate with the existing HVAC equipment to address what standard filters leave behind. In a humid climate like Gaston County's, indoor air quality is a genuine concern, not just a selling point. Mold spores, dust, pollen, and other airborne particles circulate through the system every time it runs. Upgrading the filtration side of the equipment addresses that at the source.
Your time matters, so we keep the HVAC job on schedule. For property managers, office operators, retail spaces, and restaurant operators, that means showing up when we say we will, diagnosing the problem accurately the first time, and completing the work without dragging out the timeline.
We service commercial AC systems, commercial heating equipment, rooftop units, and multi-zone systems. Qualified HVAC technicians handle the work on every commercial job, and we coordinate scheduling to minimize disruption to your tenants or customers. Commercial HVAC maintenance agreements keep systems running between repair calls and help avoid the kind of failures that shut down a business on a hot afternoon.
We'll have your system running again in no time.
A no-heat call in January or a no-cool call in August is not something you schedule around. When the system goes down completely, when a heat pump stops responding, when the furnace quits overnight, that is an emergency and we treat it like one. Same-day response is available for urgent situations, and we come prepared to diagnose and repair on the same visit whenever parts allow.
We find the fault. We make the repair. We restore the comfort.
If you are dealing with an HVAC emergency right now, call (980) 463-9789 and we will get someone to you as quickly as possible.
We have been doing this work in Gastonia since 1998, which means 28 years of residential and commercial HVAC experience in this specific climate and this specific community. The technicians who show up at your door are qualified HVAC professionals who take the work seriously and treat your home or building with respect.
The name on our trucks is our own, and we protect it. That accountability is what has kept local homeowners, landlords, and business operators calling us back for nearly three decades.
We serve Gastonia and the surrounding communities throughout Gaston County, including Mount Holly, Belmont, Dallas, Cramerton, Stanley, and Lowell. If you are nearby and need heating or cooling service, we can get to you.
When you call, a real local person gathers the details about your system and situation and gets you on the schedule. A qualified HVAC technician arrives within the agreed window, runs a thorough diagnosis, and walks you through what was found and what the repair or replacement will involve before any work begins. We give you a clear picture of the cost upfront, complete the work, and clean up before we leave.
For urgent situations, same-day service is available. Call (980) 463-9789 and we will let you know the earliest opening and get someone headed your way as quickly as possible. For planned visits and seasonal tune-ups, we can usually schedule within a short window depending on the time of year.
Check your thermostat settings and make sure the system is set to the correct mode and temperature. If the thermostat looks fine and the system still will not respond, call us at (980) 463-9789 rather than resetting the equipment repeatedly, since some faults need a technician to diagnose safely. We offer same-day and emergency response for no-heat and no-cool situations across Gastonia and Gaston County.
Yes. We are available every day from 6:00 AM to 9:30 PM, including weekends. If your system goes down and you need someone quickly, call (980) 463-9789 and we will treat it as the urgent situation it is.
We discuss pricing with you before any work begins. After the technician diagnoses the system and explains what is needed, you get a clear cost picture covering parts and labor. If the scope changes once we are into the job, we talk to you before we proceed. There are no surprise charges for work you did not agree to.
That depends on 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. We give you an honest assessment rather than defaulting to replacement when a repair is the right call. If the system is aging and breaking down repeatedly, we will walk you through the replacement options and what the upgrade would realistically cost.
You will get a clear arrival window for your technician. When they arrive, they will introduce themselves, assess your system, and explain what they are seeing before recommending any work. We keep the communication straightforward so you are never left guessing about what is happening or what it will cost.
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 and we can talk through how to handle it for your specific job.
Call us at (980) 463-9789 as early as you can and we will find a new time that works. We understand schedules change, and we would rather reschedule than have a technician show up when you are not ready.
We serve customers throughout Gaston County, including Belmont, Mount Holly, Dallas, Cramerton, Lowell, Stanley, and surrounding communities. If you are outside our usual area and want to confirm coverage, call us and we will give you a straight answer.
Make sure the technician will have clear access to the indoor air handler or furnace and the outdoor unit. If you have pets, keeping them away from the work area helps the technician move efficiently and safely. Having a general sense of when the problem started and any symptoms you have noticed, such as unusual noises, uneven temperatures, or error codes on the thermostat, is helpful but not required.

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.
