A heat pump installation in Dunwoody typically runs $3,500 to $7,500 depending on system size, ductwork condition, and whether your home needs electrical upgrades. Most installations take one to two days, and we handle the load calculation, permits, and paperwork so you’re not chasing down details.

Dunwoody homes present a specific set of challenges that generic heat pump installers miss. The housing stock here is heavy with 1970s and 1980s construction, original flex duct in attics, crawlspace foundations, and electrical panels that were sized for a different era. That’s not a reason to avoid a heat pump. It’s a reason to choose an installer who knows what they’re looking at. Our Heat Pump Installation team works Dunwoody every week, and we know what these houses need before the first box comes off the truck.

Mini Split Installation in Dunwoody
Mini Split Installation in Dunwoody is the smart play when you’re dealing with a 1970s or 1980s home that has no ductwork to a specific room, a converted garage, or a second floor that never cools evenly. Instead of tearing out drywall to run new ducts, we mount a slim indoor unit on the wall or ceiling and connect it to a small outdoor condenser with a three-inch line set. The result is zoned comfort without a full duct retrofit, and it often costs less than trying to force an old duct system to do a job it was never sized for. In Dunwoody, a mini split installation typically falls within the $3,500 – $7,500 range depending on the number of zones.
We see this most often in Dunwoody homes where the original single-zone system struggles to reach a second-floor bonus room or a kitchen addition that was never tied into the main trunk line. A mini split solves the problem at the source, with a dedicated thermostat for that one space.
When a Dunwoody Homeowner Should Choose a Mini Split
If you’ve got a room that’s always ten degrees off from the rest of the house, a mini split is usually the answer. No new ductwork, no drywall dust, no week-long project. We install and commission most single-zone mini splits in one day.
What a Mini Split Costs in Dunwoody
A single-zone mini split in a Dunwoody bonus room or garage conversion typically runs $3,500 – $5,500. Multi-zone systems covering two or three rooms fall closer to $5,000 – $7,500. The written price includes the equipment, line set, electrical connection, and a full-year written guarantee.
Heat Pump Maintenance in Dunwoody
Heat Pump Maintenance in Dunwoody is a twice-a-year job, and the timing matters more here than in drier climates. Pollen season in the spring clogs outdoor coils fast, and summer thunderstorms push humidity into crawlspaces where duct leaks live. A tune-up runs $80 – $200, and that includes a written report of what our technician actually found, not a vague checklist. We check refrigerant levels, clean the coils, test the reversing valve, inspect the duct static pressure, and verify the heat strips are staging correctly for Dunwoody’s mild but real winter demands.
If your heat pump was installed on original 1980s flex duct, maintenance is when we catch static pressure problems before they eat a blower motor. That’s a $150 – $700 repair on its own, and most of them are preventable with a consistent maintenance schedule.
What a Dunwoody Tune-Up Covers
We inspect and clean the outdoor coil, check and top off refrigerant if needed, test capacitors and contactors, measure airflow at the return, and inspect visible ductwork in the attic. You get a written price for anything we recommend before we do it. No surprise add-ons.

Why Maintenance Matters More in Dunwoody
Dunwoody’s pollen counts are consistently among the highest in metro Atlanta. That fine yellow dust packs into outdoor coils and cuts efficiency by 15 to 20 percent inside a single spring season. A clean coil is the difference between a heat pump that runs 12 hours a day in July and one that cycles normally.
Trusted Brands We Service in Dunwoody
We install and service Trane, Lennox, Rheem, and Goodman heat pumps, and we carry common replacement parts for all of them in our local stock, which means less waiting on a warehouse shipment for Dunwoody customers. If you already have a Trane air handler and want to stay in the same brand family, we’ll spec the matching heat pump. If a Goodman system makes more sense for your budget and home size, we’ll tell you straight. The equipment matters less than the installation quality, but the right brand matched to the right house is still part of the job.
We also service Carrier, York, Daikin, Bryant, and American Standard, so whatever is already in your Dunwoody home, we can work on it or replace it with a compatible system.

AfterCommon Heat Pump Installation Problems We See in Dunwoody Homes
- Collapsed flex duct from original construction. Many Dunwoody homes built in the 1970s and 1980s still have the original flex duct in the attic. After forty years of heat, humidity, and gravity, those runs collapse or kink, and a new heat pump will immediately show the strain as high static pressure and uneven temperatures.
- Undersized electrical panels. A 1970s-era panel often has no spare amperage for a modern heat pump with electric heat strips. We check the panel and load calculation before installation, so you’re not hit with a surprise subpanel upgrade mid-project.
- Renovated floor plans with old tonnage. Dunwoody homes have been through waves of renovation, additions, and kitchen remodels. Reusing the old tonnage on a changed floor plan short-cycles the compressor and does a poor job of pulling humidity out in July. Skipping the load calculation is the most expensive shortcut in the business.
- Attic-installed air handlers with poor return air. The original return drops in many Dunwoody attics are undersized, which strains the blower and makes the system loud. A new heat pump needs correct airflow to hit its efficiency numbers, and that often means a new return drop or a filter grille upgrade.

FAQs About Heat Pump Installation in Dunwoody
Because original flex duct from that era is often collapsed or kinked, and a new heat pump will push air through it at a pressure the old system could tolerate but the new blower motor won’t. High static pressure shortens blower motor life and causes uneven room temperatures. We inspect the duct runs and measure static pressure before we quote a heat pump installation in Dunwoody, and if the ducts need repair or replacement, that goes in the written price. Call (229) 537-2086 for an inspection and free estimate.
If your panel is original to the home and built in the 1970s or 1980s, there’s a decent chance it doesn’t have two spare breaker slots or the amperage headroom for a heat pump with heat strips. Our technician checks the panel rating, the existing loads, and the calculated demand before installation. If an upgrade is needed, we include it in the written quote, so there’s no surprise cost after the job starts. Call (229) 537-2086 and we’ll check it.
Yes, if it’s sized correctly and the ductwork delivers proper airflow. Dunwoody’s summer humidity is real, and an oversized heat pump will short-cycle and leave the air clammy. A properly sized system with a variable-speed air handler runs longer at lower output, which pulls more moisture out. If your crawlspace is adding humidity through duct leaks, we’ll find those during the estimate. Call (229) 537-2086 for a free evaluation.
Usually yes, but we want to know what the renovation involves. If you’re opening walls or changing the floor plan, the load calculation changes, and we’d rather install the system after the footprint is set. If the renovation is cosmetic, a heat pump goes in now and we’ll size it to the current house. Either way, we’ll give you a written price and a straight answer before you commit. Call (229) 537-2086.
Most likely the circuit is undersized for the system’s startup current, or the panel is marginal and the summer load is pushing it over the edge. It can also be a failing capacitor or a loose connection at the breaker. We trace the electrical path, check the nameplate load, and correct the issue, whether that means a new breaker, a new circuit, or a subpanel upgrade. Call (229) 537-2086 and we’ll get someone out to Dunwoody the same day.
We were called to a split-level on Meadowlake Drive where the original 1984 air handler and flex duct had never been touched. The static pressure was so high the old blower motor was pulling 1.2 inches, and two supply ducts in the attic were collapsed to half their diameter. We replaced the flex runs, corrected the plenum, and installed a properly sized Carrier heat pump with a new return drop. The temperature difference across the evaporator coil finally hit 18 degrees, which is where you want it on a Dunwoody summer afternoon.
