Here is what we take care of:
Reach out and we'll get it diagnosed today.
Before a small issue turns into a full breakdown, it pays to have someone take a look. When we arrive for an AC service call, we work through the system methodically: checking refrigerant levels, inspecting the condenser and compressor, testing airflow, and examining the evaporator coil. If your AC is not cooling, blowing warm air, or has stopped working altogether, we find the cause and explain what it takes to fix it.
Annual AC maintenance is one of the best ways to avoid a mid-summer emergency. A tune-up catches worn parts, low refrigerant, and airflow problems before they turn into expensive repairs. We offer no-pressure estimates, priced up front, so you know what you are looking at before any work begins.
For older units that are no longer keeping up, we can walk you through your air conditioner replacement options and help you choose a system that fits your home and your budget. We'll take care of the system from here.
What sets our technicians apart is straightforward: they diagnose the real problem and fix it right. A furnace repair visit covers the heat exchanger, igniter, blower motor, and control board. If your furnace is not heating, blowing cold air, or has stopped working entirely, those symptoms usually point to one of a handful of common failures, and we know where to look.
We also service boilers for customers with hydronic heating systems, so if you have radiant or baseboard heat, we can help there too. We stand behind every system we service, whether it is a quick igniter swap or a more involved repair.
Fall is the right time for a furnace tune-up. Getting the system checked before the cold sets in means fewer surprises when you actually need the heat. And when a furnace has reached the end of its useful life, we handle furnace replacement and installation for a wide range of systems and home sizes. Call and we'll get your heat or AC back on.
Cobb County sits in a genuine four-season climate. Summers here are hot and humid, winters are cool enough to demand a reliable heating system, and the swing between seasons puts real wear on HVAC equipment. That combination shapes the work we do most often in this area, and it is why the three services below come up again and again for local customers.
When a system is aging, losing efficiency, or failing repeatedly, replacing the furnace and AC together often makes more sense than patching one piece at a time. A paired replacement means both sides of the system are matched, sized correctly, and installed as a unit. You get better efficiency, more consistent comfort, and a longer service life than you would by mixing old and new equipment. We assess the existing setup, recommend the right system for the space, and handle the full installation from start to finish. Customers often ask about HVAC replacement cost upfront, and we provide clear pricing before any work begins.
Kennesaw's climate is well-suited to heat pumps. Winters here are mild enough that a heat pump handles the heating load efficiently, and the long cooling season means the same unit earns its keep all year. Heat pump adoption has been rising steadily across Georgia and the broader Southeast, and for good reason: one system handles both heating and cooling, and it does so efficiently in a climate that rarely sees extended deep freezes. We install heat pumps in new builds and as replacements for aging equipment, and we service and repair existing systems when they stop heating or cooling as they should.
High humidity is a real comfort problem in Georgia summers, and a standard air conditioner only does so much. When the air feels heavy and damp even with the AC running, a whole-home dehumidifier addresses what the cooling system cannot. It works alongside your existing HVAC equipment to pull excess moisture from the air throughout the house, not just in one room. The result is a more comfortable indoor environment, less strain on the AC, and better overall air quality. We install whole-home dehumidifiers and integrate them with existing systems. We pull the permit. We install it to code. We stand behind it.
Ready to get the comfort back? When the heat goes out on a cold night or the AC fails in the middle of a Georgia summer, you need someone who can respond the same day. We offer same-day availability and after-hours response for urgent situations, because a system-down call does not always happen during business hours.
We handle no-heat and no-cool emergencies for both residential and commercial customers. When we arrive, we protect your floors and finishes while we work, and we get straight to diagnosing the problem. The goal is to get your system back online as quickly as possible with a repair that lasts. We'll take care of the system from here.
Property managers, office managers, and building owners in the Kennesaw area rely on us for commercial heating and cooling work. We service rooftop units, handle commercial AC repair and commercial heating repair, and provide ongoing HVAC maintenance for offices, retail spaces, and multi-unit properties. Work is performed by qualified HVAC technicians with experience on both residential and commercial equipment. Residential HVAC. Commercial HVAC. One number for both.
We know that HVAC repair cost, installation cost, and replacement cost are real concerns for homeowners and business owners alike. Our process is simple: a technician assesses your system, identifies the problem or the full scope of work, and gives you pricing before anything is done. No surprises at the end of the job.
Whether you are calling about a repair estimate or trying to understand what a new system installation will run, we walk you through the numbers plainly. Our no-pressure approach means you get the information you need to make a good decision, and we are not going to push you toward work you do not need. Call and we'll get your heat or AC back on.
We serve Kennesaw and the communities around it across Cobb County and into the neighboring towns that make up this part of northwest Georgia. Our service area includes Marietta, Acworth, Smyrna, Powder Springs, Austell, Woodstock, and Canton. When you call us, you reach the people who actually show up. We are locally owned, personally accountable, and familiar with the homes and buildings in this area.
We work throughout Kennesaw and the surrounding Cobb County communities, including Marietta, Acworth, Smyrna, Powder Springs, Woodstock, Canton, Holly Springs, and Dallas. If you are not sure whether we cover your location, the fastest way to find out is to call us at (470) 995-9879.
Yes, same-day availability is our goal for urgent no-heat and no-cool situations. We know a system-down call does not always happen during regular business hours, so we do our best to respond quickly when the situation is serious. Call (470) 995-9879 and let us know what is happening so we can get someone out to you.
Call us at (470) 995-9879 and describe what your system is doing. We will ask a few quick questions, confirm your location, and get you scheduled as soon as possible. For urgent situations, we prioritize same-day response whenever the schedule allows.
For emergency no-heat and no-cool calls, we aim for same-day response. For routine repairs and tune-ups, we typically schedule within a day or two depending on current demand. Call us directly and we will give you an honest estimate of when we can be there.
For most jobs, yes. A technician needs access to the equipment and, in many cases, needs to walk through the system with you before and after the work. If your situation makes that difficult, call us and we will talk through what access arrangements make sense.
It helps to know the approximate age of your system, the make and model if you have it, and a clear description of what the system is doing or not doing. That information lets us give you a more accurate sense of what the visit will involve and how long it might take.
We price the work before anything starts and do not add surprise fees after the fact. If a technician uncovers something additional during the job, we will explain it and get your approval before proceeding. Our no-pressure approach means you are always in control of what gets done.
Deposit requirements vary by job scope. For a full system installation or replacement, we will discuss payment terms with you when we go over the estimate. Nothing is required before you have seen the pricing and agreed to the work.
A straightforward diagnostic or repair visit generally takes one to three hours. A full system replacement or installation will take most of a day depending on the complexity of the job and the condition of the existing setup. We will give you a time estimate when we schedule so you can plan accordingly.

From a quick AC tune-up to a full system replacement, we cover the complete range of heating and cooling work for Kennesaw homes and businesses. Every job gets the same attention: a thorough diagnosis, upfront pricing before work begins, and qualified HVAC technicians on the job from start to finish. Whether you are dealing with a system that stopped working or planning ahead for a seasonal checkup, the table below shows what we handle and what to expect from each service.
| Service | What the Service Includes | When You Need It | Good to Know |
|---|---|---|---|
| Heat Pump Repair & Service |
| Homes with a heat pump as the primary heating and cooling source | Heat pumps handle both seasons, so a problem in one mode often affects the other; early service avoids a full-season loss of comfort |
| Heat Pump Installation |
| Kennesaw homeowners looking for a single system that handles both heating and cooling efficiently year-round | The local climate is well-suited to heat pumps; mild winters and a long cooling season mean the system earns its keep in every season |
| Ductwork Repair & Sealing |
| Homes where some rooms are harder to heat or cool, or where energy bills have crept up without a clear reason | Leaky ducts can account for a significant share of conditioned air lost before it reaches the living space; sealing them improves comfort and efficiency |
| AC Repair & Service |
| Homeowners or businesses with a central AC that is underperforming or not running | Catching a small refrigerant or airflow problem early usually costs far less than waiting for a full breakdown in peak summer heat |
| Emergency HVAC Service |
| Anyone whose system has gone down completely, especially during extreme heat or cold | We prioritize same-day response for system-down situations because a Georgia summer or a cold winter night does not wait for a regular appointment |
| Indoor Air Quality & Air Filtration |
| Households concerned about allergens, dust, odors, or overall air quality inside the home | Upgrading filtration works alongside your existing system without requiring a full equipment replacement |
| Thermostat & Smart-Control Installation |
| Homeowners who want better temperature control, scheduling flexibility, or remote access from a phone | A smart thermostat upgrade is one of the lower-cost improvements that can meaningfully reduce how hard your system works day to day |
| Whole-Home Dehumidification & Humidity Control |
| Georgia homeowners who feel the air is heavy and damp even when the AC is running | A whole-home dehumidifier addresses moisture throughout the house, not just one room, and reduces strain on the cooling system at the same time |
| Full System Installation & ReplacementMost Popular |
| Homeowners replacing an aging or failing system, or building owners upgrading to a more efficient setup | We pull the permit, install to code, and stand behind the work; replacing both sides of the system at once avoids mismatched equipment problems |
| Furnace & AC System Replacement |
| Homeowners whose furnace and AC are both aging, or whose system has had repeated repairs without lasting results | Replacing both units together means matched equipment, better efficiency, and a longer service life than mixing old and new components |
| Heating & Furnace Repair |
| Any home or building where the heating system has stopped working or is not keeping up | Most furnace failures trace back to a handful of common parts; a diagnostic visit pinpoints the cause before any work is quoted |
| Seasonal Maintenance & Tune-Ups |
| Any homeowner or property manager who wants to avoid emergency calls and keep the system running efficiently year-round | A pre-season tune-up is the most reliable way to catch worn parts and low refrigerant before they cause a breakdown at the worst time |
How do I know if my AC or furnace needs to be replaced rather than repaired?
Age and repair history are the two biggest factors. A system that is more than 15 years old and has needed multiple repairs in recent seasons is usually approaching the point where replacement makes more financial sense than continuing to patch it. We assess the condition of the equipment during the service visit and give you an honest read on whether repair or replacement is the better value for your situation.
Why would a system stop heating or cooling even when it is running?
The most common causes are low refrigerant, a dirty coil, a failed component like an igniter or reversing valve, or an airflow restriction from a clogged filter or blocked duct. The system can run without actually conditioning the air when one of those problems is present. A diagnostic visit identifies the specific cause so the repair addresses the real issue rather than a symptom.
How often should we schedule maintenance and tune-ups?
Once a year for each side of the system is the standard recommendation. An AC tune-up in spring before the cooling season and a furnace or heat pump checkup in fall before the heating season gives you the best chance of catching problems before they turn into emergency calls. Homes with older equipment or heavy year-round use benefit from keeping that schedule consistently.
Transparent Upfront Pricing
We give you the numbers before any work starts. If something additional comes up during the job, we explain it and get your approval before proceeding.
Is HVAC installation and replacement work permitted and inspected?
Yes. We pull the permit and the work is inspected to meet local code requirements. That protects you as the homeowner and ensures the installation is done correctly from a safety and efficiency standpoint. We handle the permit process as part of the job.
What are the signs of a refrigerant or airflow problem?
With a refrigerant issue, you will typically notice the system running longer than usual, ice forming on the coil or refrigerant lines, or the air coming from the vents feeling less cold than it should. An airflow problem often shows up as uneven temperatures between rooms, weak airflow at the registers, or the system cycling on and off more frequently than normal. Either situation is worth a service call before it causes further damage.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually point to a ductwork problem, an airflow imbalance, or a room that is not well-served by the existing duct layout. Leaky or disconnected ducts are a common cause, as is a damper that has shifted out of position. In some cases, the issue is with the equipment itself. We diagnose the source and explain what it would take to correct it.
Code-Compliant Work on Every Job
We pull the permit and install to code on every replacement and installation. That protects your home and makes sure the work holds up to inspection.
What does a seasonal tune-up actually cover?
A tune-up is a systematic check of the whole system. On the cooling side, that includes inspecting the condenser and evaporator coil, checking refrigerant levels, testing airflow, cleaning the drain line, and confirming the thermostat and controls are working correctly. On the heating side, we check the heat exchanger, igniter, blower motor, and safety controls. The goal is to catch anything that is worn or out of spec before it causes a breakdown.
Can a dirty filter or coil actually hurt system performance?
A dirty filter restricts airflow, which forces the system to work harder and can cause the evaporator coil to freeze. A dirty coil reduces the system's ability to transfer heat, which means it runs longer and uses more energy to reach the set temperature. Both problems are easy to prevent with regular filter changes and annual maintenance, and both can cause real damage if left unaddressed for too long.
Same-Day and Emergency Availability
For no-heat and no-cool situations, we prioritize same-day response. A system-down call in a Georgia summer or a cold winter night does not wait, and neither do we.
How does whole-home dehumidification help in a Georgia summer?
A standard air conditioner removes some moisture as it cools, but in a climate with Georgia's summer humidity levels, it often cannot keep up. A whole-home dehumidifier works alongside the existing HVAC system to pull excess moisture from the air throughout the house. The result is air that feels more comfortable at a higher thermostat setting, less strain on the cooling equipment, and better overall indoor air quality.
How do estimates and pricing work before a job starts?
We assess the system or the scope of work first, then give you pricing before anything is done. For a repair, that means a technician diagnoses the problem and explains what the fix involves and what it costs. For an installation or replacement, we walk through the options and the numbers before you commit. We do not add fees after the fact, and we do not proceed with additional work without your approval.
What should I expect from an emergency or same-day service call?
When you call for a no-heat or no-cool situation, we ask a few questions to understand what the system is doing, confirm your location, and get a technician scheduled as quickly as the day allows. Our goal is same-day response for genuine system-down situations. When the technician arrives, they get straight to diagnosing the problem and explain the repair options before work begins.
Call (470) 995-9879 and we will talk through what your system needs, give you honest pricing, and get you scheduled as soon as possible.
