AfterHow Much Does Heat Pump Installation Cost in Marietta?
A full heat pump installation in Marietta typically runs between $4,800 and $9,200 for most single-family homes in 2026, with the average homeowner spending around $6,500 before any utility rebates or manufacturer incentives. That price includes the outdoor unit, the indoor air handler, refrigerant line set, electrical work, and labor. The spread comes down to system size, efficiency rating, and whether your existing ductwork needs modification.
If you’re comparing this against a traditional AC installation in Marietta, heat pumps generally run $1,100 to $1,900 more than a comparable central air system because the equipment itself costs more and the installation is slightly more involved. But here’s what that extra money buys you: the same unit cools your home in August and heats it in January. For many Marietta homeowners, that means no separate furnace, no gas line, and lower winter energy bills for the roughly 4 months a year we actually need heat.
Heat Pump Installation Cost Breakdown (2026)
Before we get into the factors that move these numbers, here’s the line-item reality of a heat pump install in Cobb County. These are the prices we quote in writing before any work begins, so nothing below should surprise you when you see it on an estimate.
| Cost Component | Typical Range (Marietta, 2026) | Notes |
|---|---|---|
| Heat pump unit (outdoor) | $2,800 – $5,400 | Depends on size (2 – 5 ton) and efficiency (SEER2 rating) |
| Air handler (indoor) | $1,200 – $2,600 | Matches the outdoor unit’s tonnage and coil specs |
| Refrigerant line set | $150 – $400 | Copper lines; longer runs from unit to air handler cost more |
| Electrical work | $200 – $700 | Includes disconnect box, whip, breaker, and any panel work |
| Condensate drain & pad | $100 – $350 | Includes a level composite pad or wall brackets if needed |
| Labor & installation | $1,500 – $3,200 | Half-day to full-day job; includes system startup and testing |
| Ductwork modifications (if needed) | $300 – $1,500 | Only applies when the existing ducts don’t match the new air handler |
| Permit & inspection | $100 – $300 | Required by Cobb County for any equipment changeout |
What you should expect to pay, all-in: $4,800 on the low end for a 2-ton, 14.3 SEER2 unit in a smaller home. Around $6,500 for a standard 3-ton system in a typical Marietta ranch or two-story. And $9,200 or more if you’re upgrading to a high-efficiency 20+ SEER2 variable-speed unit in a larger East Cobb or West Cobb home that needs some duct adaptation.
Two things drive the biggest swings in this table. First is efficiency rating. A 14.3 SEER2 base-model heat pump costs meaningfully less than an 18 or 20 SEER2 system, but the higher-rated unit will use 25 – 35% less electricity every summer. With Georgia Power’s current residential rates around 14¢ per kWh, that difference compounds fast in Marietta’s long cooling season. Second is equipment brand. We install every major residential brand (Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard), and parts pricing varies by manufacturer. A Goodman heat pump tends to run at the lower end of the table; a Carrier or Trane system at the higher end. The good news: the labor doesn’t change much by brand, so the price difference is mostly the hardware.
What Affects Heat Pump Installation Pricing in Marietta
Every house presents a different set of circumstances. Here are the factors that actually move your final price in the Marietta market, not the generic ones you’ll read on every other HVAC website.
- Home size and square footage. A 1,200-square-foot ranch in Marietta needs a 2-ton heat pump. A 3,200-square-foot two-story in East Cobb typically needs a 4 or 5-ton unit. Bigger equipment costs more, period. The tonnage is calculated from a load analysis (Manual J), not from the size of your old system, which was often oversized to begin with.
- Ductwork condition and configuration. Many Marietta homes were built before heat pumps were common here. If your ducts were sized for a gas furnace with high airflow temperatures, the new heat pump’s air handler may need transition fittings or minor duct modifications to deliver proper airflow. Homes with flex duct in unconditioned attics (common in Cobb County) may also need insulation or sealing work to hit the system’s efficiency numbers.
- Efficiency level you choose. The 2026 DOE minimum for heat pumps in the South is 14.3 SEER2. Every step up from there, say to 16 or 18 SEER2, adds $400 to $1,200 to the equipment cost. Variable-speed units with inverter compressors are the most expensive, but they’re also the quietest and most comfortable option for Marietta’s humidity.
- Electrical panel capacity. If your home has an older 100-amp panel or no available breaker slots, the heat pump install may require a subpanel or a panel upgrade. That alone can add $1,500 to $3,000, and it’s something an estimator will check before quoting. We flag it in writing so there’s no add-on surprise on install day.
- Access and location of the existing equipment. A ground-level outdoor unit with clear access in the backyard is a fast install. A unit tucked into a tight side yard with a fence, shrubs, or a deck overhang adds time and sometimes requires relocating the pad or adjusting the line set run. Attic air handlers in tight crawlspace sections of Marietta’s older bungalows add labor hours too.
- Removal and disposal of the old system. You’ll have an old outdoor condenser and indoor air handler that need to be removed, drained of refrigerant, and properly recycled. Most Marietta installers include this in the base price, but it’s worth confirming. At Brandt, removal and disposal are always in the written quote, never a separate line item.
One thing that does not change your price in a meaningful way: the time of year. Some companies charge a premium during the first heat wave of June or the first cold snap in January. We quote the same price in February as we do in July because the work is the same. A home comfort system should be priced on the job, not on the calendar.
Heat Pump vs. AC + Furnace: What Makes Sense in Marietta?
Marietta sits in a climate zone where this question actually matters. We get about 2,600 cooling degree days a year and roughly 2,300 heating degree days. That’s a fairly balanced demand profile, which is exactly when a heat pump earns its keep.
A traditional split system (central AC plus gas furnace) runs about $3,500 to $7,500 for the AC installation in our market, then another $4,000 to $7,000 if the furnace needs replacing too. So if both your AC and furnace are nearing the end of life, you’re looking at $7,500 to $14,500 for a complete system either way. A heat pump replaces both with one unit for $4,800 to $9,200, and it eliminates the gas line, the venting, the combustion risk, and the carbon monoxide concerns entirely.
Where a gas furnace still wins in Marietta: the coldest weeks of January and February, when natural gas at current Atlanta-area rates costs less per BTU than electric resistance backup heat. But modern cold-climate heat pumps hold their rated output down to about 17°F, which covers 98% of our winter nights. And for the remaining 2%, the unit’s auxiliary heat strips bridge the gap. Most Marietta homeowners we install heat pumps for never notice the switchover.
For older homes in the Marietta square area or near the historic district that never had central air at all, a heat pump is often the cleanest path. The ductwork requirements are the same as central AC, but you skip the gas piping and flue entirely, which can save $2,000 to $4,000 in chimney liner, gas line, and venting work.
How to Save on Heat Pump Installation
Saving money on a heat pump install in Marietta should never mean buying the cheapest equipment or hiring the lowest bidder. It should mean stacking legitimate incentives and timing your purchase sensibly. Here’s what actually works.
- Check Georgia Power rebates before you quote. Georgia Power runs seasonal rebates on qualifying heat pump installations, typically $200 to $500 for 16+ SEER2 systems. The rebate is applied at the time of installation by a participating contractor. We’ll walk you through the current rebate schedule and handle the paperwork so the discount comes off the front of the job, not as a mail-in you’ll forget to file.
- Take the federal tax credit on high-efficiency units. The Inflation Reduction Act’s 25C tax credit covers 30% of the project cost up to $2,000 for heat pumps that meet Energy Star’s efficiency requirements for the South. A qualifying 16 SEER2 or higher unit in Marietta typically clears that bar. That’s real money back on your federal return, and we’ll tell you in writing whether your selected system qualifies.
- Time the installation for shoulder season. Marietta’s installer schedules fill up hard in late May and June, and again in December and January. If you can plan the install for March, April, October, or November, you won’t necessarily get a lower price, but you’ll get more scheduling flexibility and often faster access to equipment. Some manufacturers run spring and fall promotions that trim $300 to $600 off the unit cost.
- Replace before the system dies completely. This one saves the most. A heat pump that fails in July during a heat wave often triggers an emergency replacement within 24 hours, and you’ll take whatever equipment is in stock rather than the unit that fits your home best. Planning a replacement when the current unit is 12 to 15 years old and still running gives you time to compare options and lock in pricing.
- Get a free estimate with a written price. Before you commit to any Marietta contractor, ask for a written estimate that itemizes the equipment, the labor, the permit, and the removal. If a company won’t put it in writing before the job starts, that’s a red flag. We provide a written price on every single job at Heat Pump Installation in Marietta, no exceptions. Estimates are free, and you can call (478) 662-5175 to schedule one.
What to Expect During a Marietta Heat Pump Installation
A full heat pump installation is a one-day job for most Marietta homes, occasionally spilling into a second day if ductwork modifications or panel upgrades are required. Here’s the sequence, step by step, so you know exactly what happens when the crew arrives.
- Pre-install walkthrough and written confirmation. The lead technician walks the job with you before any work begins, confirms the scope against the written estimate, and shows you the equipment being installed. You’ll see the unit’s model number and efficiency rating before it goes on the pad. The price you signed is the price you pay. No changed number at the end of the day.
- Existing equipment removal. The old outdoor unit and indoor air handler are disconnected, the refrigerant is recovered and properly recycled per EPA requirements, and the units are removed from the property. We haul everything away. You won’t have a dead condenser rusting in the backyard.
- Indoor air handler installation. The new air handler goes in first, whether it’s in the attic, a closet, or the basement. We set the unit on a vibration-isolating base or hang it from a suspension kit, connect the condensate drain with a proper P-trap, and seal the supply and return plenums.
- Outdoor unit placement and connection. The heat pump condenser is set on a level composite pad, elevated 3 to 4 inches above grade to keep it clear of Marietta rain runoff. The copper refrigerant line set is run from the outdoor unit to the air handler, brazed under nitrogen purge to prevent internal oxidation, and the system is pressure-tested for leaks.
- Electrical and controls wiring. A dedicated circuit is run from the panel to the outdoor unit’s disconnect box. Low-voltage thermostat wiring is connected, and a new thermostat is installed and configured if you’re upgrading to a smart or programmable model.
- Refrigerant charge and startup. The system is evacuated with a vacuum pump, charged to the manufacturer’s specified refrigerant weight (R-410A or R-32 depending on the unit), and the thermostat is set. We run the system through heating and cooling modes, measure the temperature split across the air handler, and verify that the defrost cycle engages correctly. You’ll see the unit producing heat and cool air before we leave.
- Final walkthrough and documentation. We show you how to operate the thermostat, explain the filter location and change interval, and hand you the warranty paperwork. Your written guarantee is included with the install. If anything fails within the coverage period, under our 365-Day Done Right Promise, we return and make it right at no charge. No argument, no re-quote, no runaround.
Every Brandt technician who walks onto your Marietta property has been background-checked and identity-verified under the Threshold Verified standard.

Heat Pump Brands We Install in Marietta
We service and install every major residential heat pump brand on the market: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Here’s the honest breakdown of how they compare for a Marietta homeowner.
- Carrier and Bryant are sister brands under the same parent company. Carrier’s Infinity line runs at the premium end with excellent humidity control, which matters in Marietta’s muggy summers. Bryant offers nearly identical engineering for $300 to $700 less per unit.
- Trane and American Standard share the same manufacturing. Trane’s variable-speed heat pumps are widely considered the durability benchmark, but you’ll pay a name premium. American Standard delivers the same compressor platform at a slightly more moderate price.
- Lennox makes some of the highest-efficiency heat pumps available, with the SL25XPV reaching 24 SEER. Parts availability in the Atlanta metro is strong, and their communicating thermostats are excellent if you want deep system diagnostics.
- Goodman and Daikin are the value leaders. Goodman offers the lowest equipment cost in the industry with solid reliability, and its parent company Daikin designs the compressors used in many other brands’ systems. A Goodman 14.3 SEER2 heat pump is frequently the right answer for a rental property or a home you may sell within 5 years.
- Rheem and York sit in the mid-range. Rheem’s RP17 and RP20 heat pumps are well-liked by our Marietta customers for quiet operation. York’s Affinity series offers strong efficiency at a competitive mid-market price.
The brand matters less than two other things: sizing and installation quality. A correctly sized Goodman beats an oversized Carrier every time. We calculate the load for your specific home, not by a rule of thumb, and we install every unit to manufacturer spec. That’s what determines whether you get 15 years of trouble-free comfort or a string of service calls.
When to Repair vs. Replace a Heat Pump in Marietta
If you already have a heat pump and it’s acting up, this is the question that matters. The short answer: if the repair costs less than 40% of the replacement value and the unit is under 12 years old, repairing usually makes sense. If you’re past that threshold, replacing is the better financial move.
Here’s the practical math. Heat pump repairs in Marietta typically run $150 to $650 for most issues: contactor replacement, capacitor, defrost board, refrigerant leak repair on an accessible line, or a blower motor. If your repair quote is $400 on a 9-year-old system that’s otherwise healthy, repair it. If your repair quote is $900 on a 14-year-old system that’s already had two service calls this year, you’re likely to spend more sustaining it over the next 3 years than a new system would cost annually over its 15-year life.
Specific signs that replacement is the right call:
- Compressor failure on a unit over 10 years old. A new compressor runs $1,800 to $3,200 installed, which is 40 to 60% of a full system replacement. It rarely makes sense on an aging unit.
- Refrigerant leaks in multiple locations. If you’ve had two or more leak repairs in three years, the system is telling you something. Older R-410A systems are still serviceable in 2026, so a single repairable leak is fine to fix. The third leak is your signal to move on.
- Your system is R-22. If your heat pump was installed before 2010, it may still run on R-22 refrigerant, which has been out of production for years. The refrigerant alone now costs $150 to $250 per pound, and most R-22 systems need 4 to 10 pounds for a recharge. That’s the point where a recharge costs more than any realistic repair value.
- Electric bills creeping upward. A heat pump that’s lost efficiency due to coil corrosion or compressor wear will show it on your statement. If your summer cooling costs have risen 20% or more compared to three years ago and you haven’t changed your usage patterns, the equipment is degrading.
If you’re on the fence, call us for a straight assessment. We’ll tell you honestly whether the repair is worth doing, and we’ll show you the numbers either way. Our repair work is priced in writing before anything starts, and every repair carries a written guarantee. If a repair fails within the guarantee period, the return visit is free under our 365-Day Done Right Promise.
Frequently Asked Questions About Heat Pump Installation Cost
How much does a heat pump cost for a 2,000 square foot home in Marietta?
A heat pump for a 2,000-square-foot home in Marietta typically runs $5,500 to $8,000 installed in 2026. That’s based on a 3-ton system, which is the most common size for a 2,000-square-foot Cobb County home with standard ceiling heights and typical insulation. If your home is exceptionally well insulated or shaded, a 2.5-ton unit might suffice. The labor and installation make up about 35 to 40% of that total, with the equipment accounting for the rest. Call (478) 662-5175 for a written quote on your specific home.
Is a heat pump worth the extra cost over central AC in Georgia?
For most Marietta homeowners, a heat pump costs $1,100 to $1,900 more than a central AC system of the same size and efficiency, but it replaces both your AC and your furnace. That’s not really an extra cost; it’s a consolidation of two systems into one. Since Marietta sees roughly 2,300 heating degree days a year, the heating mode gets real use from November through March. You eliminate the gas furnace entirely, along with its associated gas line, venting, and combustion safety considerations. Over a 15-year lifespan, most Marietta homeowners come out ahead financially by $2,000 to $5,000 compared to replacing an AC and furnace separately.
How long does a heat pump installation take in Marietta?
A standard heat pump installation in Marietta takes one full day, typically 6 to 10 hours from arrival to startup. If the job requires ductwork modifications, electrical panel upgrades, or relocation of the equipment pad, plan for a second partial day. We install the system, test both heating and cooling modes, and walk you through the thermostat before we leave. The estimate includes the complete scope, so you’ll know the timeline before the crew arrives.
What size heat pump do I need for my Marietta home?
Most Marietta homes need between 2 and 5 tons of heat pump capacity. The exact size depends on square footage, ceiling height, window area and orientation, insulation levels, and the home’s air leakage. A proper load calculation (Manual J) is the only correct way to determine this, and a 2,000-square-foot home usually lands at 3 tons while a 1,200-square-foot ranch lands at 2 tons and a 3,500-square-foot two-story lands at 4 to 5 tons. Anyone who quotes a unit size based on a rule of thumb without asking about your specific home’s construction should give you pause.
Does a heat pump require a permit in Marietta?
Yes, all heat pump installations and replacements in Marietta and unincorporated Cobb County require a mechanical permit, which typically costs $100 to $300. The permit ensures the installation meets Cobb County’s mechanical code and includes an inspection of the completed work. We pull the permit, schedule the inspection, and confirm everything passes before the job is considered complete. The permit cost is included in our written estimate.
Can you install a heat pump same-day or next-day in Marietta?
In most cases, yes. If your existing system has failed completely and you need heat or cooling immediately, we can typically install a heat pump within 24 to 48 hours in the Marietta area, depending on equipment availability for your home’s size. We keep a local inventory of common 2 to 4-ton units and can often accommodate same-day installation for standard configurations. Call (478) 662-5175 and a live person will answer, day or night, to schedule your install.
Do you offer financing for heat pump installation in Marietta?
Yes, financing options are available for qualifying Marietta homeowners, with monthly payments typically structured over 12 to 60 months. A standard heat pump installation financed over 48 months usually lands in the $140 to $230 per month range for a mid-size system, depending on your credit profile and the selected equipment. We’ll show you the full cost, the monthly payment, and the total interest before you sign anything. Nothing is financed or billed without your written approval.
