Get your free estimateFast, Reliable Heat Pump Installation Across Johns Creek
A new heat pump installation in Johns Creek typically runs between $3,500 and $7,500, and the right unit for your home depends on square footage, zoning, ductwork condition, and whether natural gas is available on your street. Most Johns Creek homeowners we work with are replacing aging 1990s-era equipment in large custom homes, often with multi-zone systems that need careful integration, not just a box swap. We dispatch crews to Johns Creek neighborhoods from our metro Atlanta office, and our techs know the local housing stock well enough to spot problems before they become change orders. Call (229) 537-2086 for a free, no-pressure estimate on a heat pump sized for your actual house, not a rule-of-thumb guess.

Key takeaways:
- Heat pump installation in Johns Creek: $3,500 – $7,500 depending on size, SEER2 rating, and ductwork scope
- Large custom homes with multiple zones require a load calculation before any equipment is ordered
- We service Carrier, Trane, Lennox, and Goodman heat pumps, plus five other major brands
- Every quote is written, itemized, and fixed before we start. No surprises at the door.
Why Dalton Heating & Air Alpharetta Is Johns Creek’s Preferred Heat Pump Installation Company
Dalton Heating & Air Alpharetta operates under The Garrison Standard, a set of operating rules that has governed how we work since 2003. The Garrison Code, as our crews call it, is simple: arrive inside the stated window, put the price in writing before any work starts, do the job by the book, leave the site clean, and stand behind the work for a full year. That is not a pitch. It is the rule our techs are held to on every call in Johns Creek, and it is why homeowners in neighborhoods like Country Club of the South, Medlock Bridge, and St Ives tend to call us back when the second system in the house needs replacing.
Marco Benitez leads our installation crews, and he is particular about one thing on Johns Creek jobs: the load calculation. Johns Creek homes are not cookie-cutter. A 5,000 square foot house with vaulted ceilings and a finished basement has a different thermal profile than a 2,800 square foot ranch. Marco’s team runs the numbers on every heat pump installation so the unit you pay for is the unit your house actually needs. Oversized equipment short-cycles and leaves Johns Creek basements feeling clammy. Undersized equipment runs constantly and burns out compressors early. Neither is acceptable.
Our Heat Pump Installation team schedules Johns Creek jobs Monday through Saturday, and our live phone line is answered around the clock by a real person in our metro Atlanta office. If your heat pump fails during a July thunderstorm or an April cold snap, you will not get a voicemail queue.

Heat Pump Maintenance in Johns Creek
Heat pump maintenance in Johns Creek is a twice-a-year job that costs $80 – $200 per visit, and most homeowners see the value the first summer they skip it. A heat pump moves heat in two directions, so it works harder than a furnace or straight AC unit. In Johns Creek’s humid subtropical climate, the cooling season runs from April through October, and the heating season, while mild, still pushes equipment to run on defrost cycles during damp, near-freezing nights. Maintenance means cleaning the coils, checking refrigerant charge, testing the reversing valve, and verifying that the defrost board is not going to ice over when a cold front rolls through in January.
We also test airflow. That part is easy to overlook but hard to overstate on Johns Creek homes with multi-zone ductwork.
Coil Cleaning and Airflow Testing
A dirty evaporator coil forces the compressor to run hotter and longer than designed. In Johns Creek’s pollen-heavy spring, outdoor coils collect a layer of tree pollen and cottonwood fuzz that chokes airflow and drives up energy use. We clean the coils, measure static pressure, and flag duct restrictions before they take out a blower motor.
Reversing Valve and Defrost Cycle Check
Heat pumps in Johns Creek switch between heating and cooling dozens of times per season. The reversing valve is what makes that switch, and when it sticks, you get cold air in heating mode or warm air in cooling mode. We test the valve and the defrost sensor on every maintenance visit because catching a failing valve costs $80 – $200. Replacing a failed one later costs a lot more.
Geothermal Heat Pump Installation in Johns Creek
Geothermal heat pump installation in Johns Creek is a bigger project than an air-source system, but it is the right call for some of the larger, all-electric homes in the area, particularly on rural lots around the northern edge of the city where the yard has room for ground loops. A geothermal system uses the constant temperature of the earth, roughly 55 to 60 degrees a few feet down, to move heat instead of fighting outdoor air temperatures. In Johns Creek’s climate, that means steady cooling through July and August and stable heating in January without the efficiency drop that air-source heat pumps see when outdoor temperatures fall toward freezing.
The upfront cost on geothermal runs higher than air-source equipment, but the operating cost is lower. We do not publish a single price for geothermal because the loop field size, drilling depth, and excavation scope vary too much from lot to lot. What we do promise is a fixed, written quote before any work begins, and a full year of coverage under the 365-Day Done Right Promise if anything is not done to spec.

Loop Field Design on Rural Lots
Johns Creek has a mix of tight suburban lots and larger properties, particularly north and east of the Chattahoochee. On lots with open ground, we design horizontal or vertical loop fields based on soil type and available area. On smaller lots, a vertical bore field may be required. We evaluate the site before quoting so the loop is sized for the actual heat load, not a square-footage guess.
Ductwork Integration with Existing Systems
Many Johns Creek homeowners considering geothermal already have ducted forced-air systems. Geothermal units connect to existing ductwork, which keeps installation less invasive than some expect. The catch is that undersized returns in large custom homes, a common issue in 1990s builds, limit what any system can deliver. We measure static pressure and duct capacity before recommending geothermal, because a high-efficiency unit on restricted ductwork will never hit its rated performance.
Trusted Brands We Service in Johns Creek
Our techs are factory-trained on nine major HVAC brands, and on Johns Creek heat pump jobs we most often install Carrier, Trane, Lennox, and Goodman equipment. Each brand has strengths: Carrier and Trane lead on SEER2 efficiency and zoning compatibility, Lennox is common in newer Johns Creek builds, and Goodman delivers solid value on straightforward replacements where the ductwork is already in good shape. We stock common parts for these systems in our metro Atlanta warehouse, which means a failed control board or defrost sensor on a Johns Creek job does not wait on a two-week backorder. When we quote a system, we include the specific model number and the full warranty terms in writing. No vague promises.

AfterCommon Heat Pump Installation Problems We See in Johns Creek Homes
- Aging zone dampers in Country Club of the South and St Ives. Many original 1990s-era homes have powered dampers that are now stuck, stripped, or failed. New heat pumps get installed, and the upstairs still will not cool because the damper never opens. A proper installation includes checking and often replacing those actuators.
- Undersized returns in large, multi-zone homes. Builders in the 1990s and 2000s often cut return-air sizing to save space. The result is high static pressure that kills blower motors and compressors early. We measure this before recommending equipment.
- Oversized heat pumps on exposed rural lots. Johns Creek has no shortage of open, tree-sparse properties with nothing to block wind. Installers who skip the load calculation put in bigger equipment to be safe, and the unit short-cycles through humid summer days, leaving the house damp and clammy. A Manual J load calc fixes this before the unit goes in.
- Finished basements with separate systems. Many Johns Creek homes have a second heat pump or straight AC system for the basement. When one system fails, we check whether the two systems share ductwork or refrigerant lines before quoting a replacement. Assuming they are independent is an expensive mistake.

FAQs About Heat Pump Installation in Johns Creek
The problem is not usually the heat pump itself. In homes built in the 1990s and 2000s, powered zone dampers direct conditioned air to different floors, and after 20-plus years those damper actuators stick or fail, so air never reaches the upstairs ducts. The fix is to test and replace the damper actuators and control board when installing the new heat pump. Call (229) 537-2086 and we’ll diagnose your system before quoting equipment.
Start with a Manual J load calculation that accounts for the home’s exposure to wind and sun, not just square footage. Open rural lots see higher heat loss in winter and higher solar gain in summer, which changes the required tonnage. We run this calculation on every installation, and it typically takes under an hour. Call (229) 537-2086 to schedule a free load assessment.
Yes, and in many Johns Creek homes the basement already has a separate heat pump or straight AC unit. The key is verifying whether the two systems share ductwork or refrigerant lines before replacing either one. We inspect both systems during the estimate so you are not quoted for work that conflicts with the other unit. Call (229) 537-2086 to book a site visit.
In most cases, yes. High ceilings, especially open foyers and two-story great rooms, add a lot of conditioned volume, which means the heat pump runs longer through the cooling season. Higher SEER2 units cost more upfront but consume less electricity per hour, and the math usually works in a Johns Creek climate where the AC runs six-plus months a year. We quote SEER2 ratings side by side so you can see the numbers for your actual house.
Twice-a-year maintenance is the baseline: one visit before cooling season and one before heating season. In Johns Creek’s humidity, coil cleaning and drain line flushing matter more than in drier climates because mildew and algae build up faster in the condensate line. We also check refrigerant charge and reversing valve function. Each visit runs $80 – $200, and includes a written report of what was found.
