Styles & brands we work with
Furnace Installation
Furnace Installation is the full replacement or first-time installation of a gas or electric furnace that heats your Marietta home during the colder months, typically from October through March when overnight lows in Cobb County regularly dip into the 30s. Most furnaces last 15 to 20 years, so if yours is older than that, short-cycles, or has needed multiple furnace repairs in the last two seasons, it’s time to look at replacement rather than another patch job. Halden Heating and Air Marietta installs furnaces of every major fuel type and efficiency tier, and the work falls within our standard $3,500 – $7,500 installation range, with a written price locked before we start. We’ll calculate the correct furnace size for your square footage rather than just swapping in whatever was there before.
Gas Furnace Replacements
If your current system is a gas furnace, we’ll check the heat exchanger, burner assembly, and venting as part of the install scope, not as an upsell. That matters because a cracked heat exchanger isn’t a repair item; it’s a safety item. Our replacement includes a full combustion safety check before we call the job done.
Electric Furnace Conversions
Some older Marietta homes still run electric resistance furnaces, which work but cost a lot to run. We’ll show you the actual operating cost difference between electric and gas or a heat pump before you commit. The written quote includes the equipment, the labor, and the removal of the old unit.
HVAC Installation
HVAC Installation covers the complete heating and cooling system: the indoor air handler or furnace, the outdoor condenser or heat pump, the evaporator coil, the line set, and the thermostat that runs it all. In Marietta, where summers push 90-plus degrees with humidity and winters still bring frost on the grass, a matched system matters more than a name-brand sticker. Halden Heating and Air Marietta replaces full HVAC systems starting around $3,500 and typically running to $7,500, depending on home square footage and the efficiency tier you choose. We size the system using a Manual J load calculation, which accounts for your home’s window exposure, insulation, and local climate data, not a rule-of-thumb guess.
Full System Replacement
When both the furnace and the AC are over 15 years old, replacing them together costs less than doing them separately. You’ll save on labor because we’re already pulling the old equipment and running new electrical and refrigerant lines once, not twice. The 365-Day Done Right Promise covers the entire scope.
Matched System Sizing
A mismatched system, where the outdoor unit doesn’t match the indoor coil, kills efficiency and shortens the compressor’s life. We only install matched systems from the brands we certify through, including Trane, Goodman, and Rheem. Your quote will show the model numbers of both the indoor and outdoor units before you sign anything.
Heat Pump Installation
Heat Pump Installation is the installation of a system that both heats and cools by moving heat into or out of your home, which is why heat pumps work so well in Marietta’s moderate winter climate. Because a heat pump doesn’t burn fuel, it can cut your winter heating bill compared to electric resistance heat, and in summer it operates essentially like a standard AC. Halden Heating and Air Marietta installs heat pumps in the same $3,500 – $7,500 range as a conventional AC, but the better comparison is to a full HVAC system, because a heat pump replaces both your AC and your furnace. We’ll show you the all-in number and a written price before we order the equipment.
Cold-Climate Air Source Heat Pumps
Modern heat pumps hold their efficiency down to much lower outdoor temperatures than the old units did. If your home currently has no natural gas line, or if your gas furnace is on its last legs, a modern air source heat pump is often the smarter long-term play. We’ll run the operating cost numbers for your specific utility rates here in Marietta.
Dual Fuel Systems
A dual fuel setup pairs a heat pump with a gas furnace, so the heat pump handles the mild Marietta winter days and the furnace kicks in on the rare nights when the temperature drops hard. It costs a bit more up front than a straight AC replacement, but we’ll show you the payback math before you decide. No pressure; the written quote stands either way.
Ductless Mini Split Installation
Ductless Mini Split Installation puts a compact indoor air handler on a wall or ceiling in a specific room or zone, connected to a quiet outdoor unit by a small refrigerant line instead of ductwork. It’s the best answer for Marietta homes with no existing ducts, or for rooms that never quite cool correctly, like a converted garage, a sunroom off Powder Springs Road, or a bonus room over the garage in Vinings. Halden Heating and Air Marietta installs single-zone and multi-zone mini splits, and while smaller single-room jobs can land below our main $3,500 – $7,500 range, whole-home multi-zone systems commonly fall within it. Every quote includes all electrical work, the line set, the wall mount, and the removal of old equipment if present.
Single-Zone Mini Splits
A single indoor unit connected to one outdoor condenser is ideal for a primary bedroom, an in-law suite, or a home office that runs hot. These installs are usually done in a single day. You’ll get a live arrival time for the crew and a written price before they roll up.
Multi-Zone Systems
Multi-zone mini splits let one outdoor condenser run up to four or five indoor heads, each with its own thermostat. That’s how you cool a 1950s Marietta ranches with no ductwork without tearing out walls to add it. We’ll map out which rooms get which size head, and why.
AC Replacement
AC Replacement is the removal of your old outdoor condenser and indoor coil and the installation of a new, matched cooling system designed for your home’s actual load. Marietta summers are humid enough that an underperforming AC isn’t just uncomfortable; it can make your whole house feel damp, and in homes with elderly residents or babies, indoor heat is a health risk we don’t take lightly. Halden Heating and Air Marietta handles AC replacements in the $3,500 – $7,500 range, and every single replacement starts with a load calculation, not a guess based on your old unit’s size. If your existing air conditioner is over 12 years old, uses R-22 refrigerant (which is no longer produced and has gotten very expensive to recharge), or has needed multiple AC repairs in the last two summers, replacement usually makes more financial sense than another patch.
Replacing R-22 Systems
If your current unit runs on R-22, also called Freon, you’re looking at refrigerant recharge costs that climb every year because the refrigerant itself is being phased out. Replacing that system with a modern unit that uses R-410A or another current refrigerant ends that problem entirely. We’ll dispose of the old refrigerant properly, which is a legal requirement, not an option.
Upgrading Efficiency Tiers
The efficiency of an AC is measured in SEER2, a rating that tells you how much cooling you get per dollar of electricity. A 14 SEER2 system and a 17 SEER2 system both cool your house, but the higher-rated one costs less to run every month. We’ll show you the price difference and the estimated monthly operating cost for each tier so you can make the call with real numbers.
Central Air Conditioning Installation
Central Air Conditioning Installation is the installation of a complete ducted cooling system: the outdoor condenser, the indoor evaporator coil, the refrigerant line set, and the thermostat, all working through your home’s existing ductwork. It’s the most common cooling setup in Marietta, especially in the subdivisions around Kennesaw AC Installation areas, Acworth, and Mableton where most homes already have ducts from the original build. Halden Heating and Air Marietta installs central AC systems in the $3,500 – $7,500 range, and the variance comes down to home size, the SEER2 efficiency rating you choose, and whether your ductwork needs modification. The written quote covers everything: equipment, labor, line set, electrical, and haul-away of the old unit.
Ductwork Assessment
Before we install a new central AC, we inspect your existing ductwork for leaks, collapsed sections, and poor airflow design. In older Marietta homes, poorly designed or leaky ducts can waste 20 to 30 percent of the cooling you’ve paid for. If repairs are needed, we show you photos and a separate line item, and you decide before we proceed.
Proper Refrigerant Charging
One of the most common reasons a brand-new AC doesn’t cool properly is that the installer didn’t charge the refrigerant correctly at startup. We weigh in refrigerant to the manufacturer’s exact specification using digital gauges and verify subcooling and superheat on every install. It’s a technical step you’ll never see, but it’s the difference between a system that cools for 15 years and one that struggles by year three.
Brands We Service
We install and service Trane systems, and we stock common OEM parts for their current lineup. Trane’s variable-speed compressors are a solid fit for Marietta’s hot, humid summers because they run longer at lower speeds, which pulls more moisture out of the air. If you have a Trane that’s still under warranty, we handle the warranty paperwork so you get every dollar you’re owed.
We also work extensively with Goodman and Rheem equipment. Goodman tends to hit a lower price point for the same efficiency rating, which matters if you’re replacing a system on a budget. Rheem’s modern heat pumps have a strong track record in metro Atlanta’s climate, particularly for their defrost controls during the occasional frost. Whether you have a Lennox, a York, a Carrier, or any other make, we can diagnose, service, and replace it. Bring us the brand and model number and we’ll tell you the truth about what it costs to keep running versus replace.

AfterSigns You Need a Pro Right Now
- Your AC is blowing warm air. This usually means low refrigerant, a failed compressor, or a frozen evaporator coil. Running it like this for days can turn a recharge into a full compressor replacement. Turn it off and call (229) 514-0545.
- Odd noises are coming from the outdoor unit. Grinding, squealing, or banging sounds from the condenser often point to a failing compressor or a loose fan motor. A compressor failure left unchecked can scatter debris through the refrigerant lines, ruining the indoor coil too. Don’t wait on a noise; the repair bill only grows.
- Your energy bill spiked with no change in usage. When an aging AC works harder to deliver the same cooling, the electric meter notices even if you don’t. A sudden 20 to 40 percent jump in summer usage is often the first sign of a capacitor, motor, or refrigerant issue. Catching it early keeps the repair under a few hundred dollars instead of a full replacement.
- Humidity inside your Marietta home feels sticky even when the AC runs. One of the jobs of a properly working AC is to remove moisture from the air. If your system is short-cycling or low on refrigerant, it cools the air slightly but leaves the moisture behind. That’s how you get that clammy, swampy feeling indoors, and it’s also how you get mold growth in ductwork.
- The system is over 12 years old and needs a repair you’d call “major.” A dead compressor or a leaking evaporator coil on a 12-plus-year-old unit is the point where repair costs start chasing replacement costs. If a single repair quote is over $1,500, we’ll show you the replacement math side by side so you can choose with clear eyes.

You’ll get before-and-after photos.
- 5
Post-install walkthrough and paperwork. After the system is commissioned, we walk you through the thermostat, the filter location, and the warranty. You get a written copy of the 365-Day Done Right Promise. If anything isn’t cooling right within a year, we come back at no charge.
How Much Does AC Installation Cost in Marietta?
A typical AC Installation pricing in Marietta runs $3,500 to $7,500, with the spread driven by a few factors you can control and a few you can’t. A smaller single-story home around 1,200 to 1,500 square feet in a neighborhood like Fair Oaks or Austell is usually on the lower end of that range. A larger two-story home in Vinings or Powers Ferry with high ceilings and lots of south-facing glass lands on the higher end. The efficiency rating you choose also moves the number: a base 14 SEER2 system costs less up front than a 17 SEER2 system, but the higher-rated one costs less every month on your Georgia Power bill. We’ll show you both numbers.
What affects the price: whether your ductwork needs sealing or modification, how far the line set needs to run from the condenser to the indoor coil, whether you need any electrical panel work, and whether you’re replacing just the AC or doing a full HVAC swap. The best way to avoid overpaying is to get a written, line-item quote that shows the equipment price, the labor price, and any extras separately. That’s exactly what we provide. There is no charge for the estimate, and the number we quote is the number you pay.
