Kennesaw HVAC Company handles residential and commercial heating and cooling work across Kennesaw and the wider Cobb County area. Whether the call is about an AC that stopped cooling in the middle of July, a furnace that quit on a January night, a heat pump that needs replacing, or a full system installation in a new build, this is the number to call. Systems like yours are familiar ground in these neighborhoods. We know what runs here, what ages out first, and what the local climate puts these systems through season after season.
We pick up the phone. We scope the job. We book the visit.
When you call, someone who knows the trade answers. The job gets described, the price gets confirmed, and the visit gets scheduled before anything else moves. No pressure and no gimmicks, just straight HVAC answers. Call us and we'll handle the rest.
From aging systems to brand-new installs, we cover the full range of HVAC work for homes and commercial properties in Kennesaw and across Cobb County. That means AC repair and service, furnace repair, heat pump repair and installation, full system replacement, mini-split and ductless systems, and boiler service. The work runs from a single-room ductless unit in a garage addition to a whole-building replacement for a small commercial property.
Property managers and commercial clients call us for light commercial installs, multi-unit repairs, and scheduled maintenance on buildings along commercial corridors. Homeowners call about everything from a noisy condenser to a system that has simply reached the end of its useful life. The work is the same either way: figure out what the system needs, confirm the price, and get it handled.
We serve Kennesaw, Marietta, Acworth, Smyrna, Woodstock, Powder Springs, Austell, and the communities throughout Cobb County. If you are nearby and your heating or cooling needs attention, we can scope the job on the call.
Keeping a home comfortable starts with a system that runs right, and that means understanding what is actually wrong before any work begins. Every service call starts with a diagnosis. The technician who comes out checks the system, identifies the cause, and explains what the repair or replacement involves before anything is agreed. Here is what that looks like across the main categories of work we handle.
Georgia summers are long and they are not forgiving. When an AC stops cooling, starts blowing warm air, freezes up, leaks water, or keeps cycling off before the house reaches temperature, the visit covers a full diagnostic: refrigerant level and leak check, capacitor and contactor condition, condenser coil and evaporator coil inspection, and airflow through the air handler. The goal is to find the actual cause rather than replace parts until something works. The thermostat is confirmed as communicating before sign-off, so the system is verified to be running correctly before the visit ends.
Kennesaw winters are mild compared to much of the country, but a furnace that fails in January still needs fast attention. A furnace blowing cold air, cycling off before the house warms up, making a banging or rattling noise, or simply not igniting at all are all situations we handle. Heat pump heating systems fall into this category too: if the system is not producing heat in heating mode, the diagnostic covers the reversing valve, refrigerant charge, defrost cycle, and auxiliary heat strips. We'll get the repair scoped and scheduled.
Heat pumps are well-suited to Cobb County's climate. The winters are short enough that a heat pump handles the load most of the season, and the long cooling season is where the efficiency advantage shows up most. We handle heat pump repairs across all common failure modes: not heating, not cooling, short-cycling, icing over, or making noise. When a heat pump has reached the end of its life, we handle the full replacement, including sizing the new unit for the home.
Mini-split and ductless systems fall under this category too. For rooms without existing ductwork, additions, sunrooms, or detached structures, a ductless mini-split is often the right answer. We install and service these systems the same way we handle ducted heat pumps.
At some point, repair is no longer the right answer. A system that has failed repeatedly, is consuming more energy than it should, or simply cannot keep the house at temperature on a hot Georgia afternoon is a candidate for replacement. We handle whole-home HVAC replacement and new system installation, including central air installation for homes that are adding cooling for the first time.
The price is confirmed on the call before anything is scheduled, based on what the job involves. Code-compliant HVAC work on every job is not a tagline. It is what the installation requires to pass inspection and perform correctly over the long term.
Rooms that won't cool, rooms that won't heat, or a house where one end is always a different temperature than the other often point to the duct system rather than the equipment. Leaking ducts waste conditioned air before it reaches the living space, and the cause of an uneven house actually investigated is usually found in the ductwork, not the unit. We handle duct sealing, ductwork repair, and full ductwork inspection as standalone services and as part of larger system work.
Indoor air quality work runs alongside ductwork service. Air filtration installation, whole-home air filtration systems, UV air purifiers, and air scrubbers all connect to the existing duct system and address what is circulating through the home. In a climate as humid as Georgia's, what the air carries matters as much as what temperature it is.
A thermostat that is not reading correctly, not communicating with the system, or simply at the end of its life affects everything the HVAC system does. We install programmable thermostats, smart thermostats, and whole-home control systems. Before the visit ends, the thermostat is confirmed as communicating with the system and the schedule is verified as set correctly. A thermostat that was installed but not confirmed working is not a finished job.
The homes and systems in this area have their own demands, and timing the maintenance around the seasons makes a real difference. A spring AC tune-up before Georgia heat arrives covers coil cleaning, refrigerant level check, capacitor condition, blower and air handler inspection, and a full airflow check. A fall furnace or heat pump tune-up before the cold covers the heat exchanger, ignition system, filter condition, and thermostat calibration.
The reason to schedule maintenance before the season starts is straightforward: a capacitor that is weakening will fail on the hottest day of the year, not in April when the load is low. Catching it during a tune-up costs less and causes less disruption than an emergency call in August. A maintenance visit also turns up duct leaks, refrigerant loss, and airflow problems that have been building quietly.
We handle HVAC inspections as part of the maintenance visit, so the whole system gets looked at, not just the components that were scheduled. Pick up the phone and we'll get started.
Ready to get the comfort back? No heat in January and no cooling in a Georgia July are not situations that wait for a convenient appointment. When the system is down, the call gets answered, the job gets scoped on the phone, and a price is given before anything is scheduled. We take emergency calls every day, 9:00 AM to 8:00 PM.
Clear answers. Real pricing. Real fast response.
If the system is not running and the house is not comfortable, call. The visit covers a full diagnostic, and the scope of the repair is explained before any work begins. HVAC emergencies in Kennesaw and across Cobb County are handled the same way as any other call: the job gets described, the price gets confirmed, and the work gets done.
HVAC repair costs and replacement costs vary depending on what the system needs, what equipment is involved, and what the job actually requires. The honest answer is that the price is confirmed on the call, before anything is scheduled, based on a description of the system and the problem. There is no estimate given before the diagnostic, because a number given before the system has been looked at is not a real number.
What you should ask when you call: what does the service call cover, what does the diagnostic involve, and what happens to that cost if the repair goes ahead. Those are fair questions and they get straight answers.
We do not push toward a particular repair or replacement. The job is to tell you what the system needs and what it costs, then let you decide. No pressure and no gimmicks, just straight HVAC answers. We're ready to get your heating and cooling running again.
We serve Kennesaw and the communities throughout Cobb County, including Marietta, Acworth, Smyrna, Woodstock, Powder Springs, Austell, and Roswell. The housing stock across this area runs from older ranch homes and split-levels built in the 1970s and 1980s to newer construction in planned communities, with a mix of commercial properties along corridors like Barrett Parkway and Cobb Parkway.
Older homes often have ductwork that has never been sealed and original equipment that has been repaired several times over. Newer construction sometimes has systems that were sized for the build spec rather than for how the home is actually used. Both situations are familiar work, and the approach is the same either way: look at what is actually there, explain what it needs, and confirm the price before anything starts.
If you are in Kennesaw or anywhere in the surrounding area and need heating or cooling work handled, call to get the job scoped.
When you call, someone who knows the trade answers. That person can take a description of the system, discuss what the problem sounds like, and scope the job on the phone before anything is scheduled. The call is not routed through an automated menu or handled by someone reading from a script. Whoever picks up knows the trade and can scope the job.
Before any work begins, the scope of the job is explained and the price is confirmed. You are not asked to approve work before you understand what it involves or what it costs. That applies to a simple repair visit and to a full system replacement. The goal is that nothing about the visit comes as a surprise once the technician is on site.
The person who comes out starts with a full diagnostic of the system rather than going straight to a parts list. They identify the cause, explain what the repair or replacement involves, and give you the price before any work starts. If additional issues are found during the visit, those get explained separately before anything extra is agreed. The thermostat is confirmed as communicating correctly before the visit is closed.
A symptom like a system not cooling can have several different causes, and the right repair depends on what the diagnostic actually finds. A system that lost refrigerant last summer may have a slow leak that was not located the first time, or a capacitor that was marginal may have finally failed. The diagnostic is aimed at the root cause, not just the presenting symptom, so the recommended work can differ even when the symptom looks the same.
If the repair requires a part that is not immediately available, the situation gets explained on the visit and a timeline for the follow-up gets discussed. The diagnostic visit is not left open-ended. You will know what part is needed, what it involves, and when the follow-up can be scheduled. We will confirm the details before the technician leaves the property.
If something is not right after a completed visit, call (470) 995-9879 and describe what the system is doing.
The situation gets assessed on the phone and a follow-up visit gets scoped from there. A problem that is clearly connected to work we completed is handled without treating it as a brand-new service call. We want the system running correctly, not just closed out on the paperwork.
Appointment details are confirmed on the phone when the visit is booked. The date, the scope of the visit, and the service call rate are all covered in that conversation.
If anything changes before the visit, call (470) 995-9879 and we will update the booking.
We do not assume details carry over from a previous call without confirming them again.
Georgia's climate puts specific demands on HVAC equipment. Long, humid summers push cooling systems harder than in drier climates, and the shoulder seasons bring moisture that a standard AC system may reduce but not eliminate. Older homes in this area often have ductwork that has never been sealed and original equipment that has been patched rather than replaced. Systems like yours are familiar ground in these neighborhoods, and the diagnostic reflects what actually goes wrong here rather than a generic checklist.
A job that starts as a straightforward repair sometimes reveals a secondary problem once the system is open. Duct leaks found during a cooling repair, a heat exchanger that shows wear once the furnace is inspected, or a refrigerant leak that points to a corroded line set are all examples of work that expands once the actual condition of the system is visible. When that happens, the additional scope gets explained and priced before any extra work proceeds. Nothing gets added to the job without a conversation first.
We check the furnace. We check the AC. We leave it running right.
Kennesaw HVAC Company is available every day, 9:00 AM to 8:00 PM.
