A heat pump is an air conditioner that learned to run in reverse: in summer it moves heat out of your house, and in winter a reversing valve flips the refrigerant flow so the same compressor pulls heat from outdoor air and delivers it inside. Because it moves heat rather than generating it, a heat pump routinely delivers two to three times more heat energy than the electricity it consumes, which is why so many Dunwoody, GA homeowners are switching as older equipment ages out. Modern cold-climate models with variable-speed inverter compressors keep producing useful heat far below freezing, a genuine engineering leap over the units that gave the technology its old reputation.
Great heat pump performance starts with design work, and that is where Dunwoody HVAC earns your trust. A heat pump has to be sized for two loads, summer cooling and winter heating, and the design has to find the balance point where the outdoor temperature meets the unit's capacity curve. Our technicians run the load calculation, compare single-stage, two-stage, and variable-speed inverter equipment against your climate and ductwork, and plan the backup heat properly, either electric strips staged below the balance point or a dual-fuel setup with a gas furnace that takes over in deep cold. We also check your electrical service and ducts, since heat pumps deliver lower supply temperatures than furnaces and need solid airflow to feel comfortable.
Installation follows the same discipline as every Dunwoody HVAC system: line set pressure-tested and evacuated to a micron-verified vacuum, charge weighed in and confirmed with superheat and subcooling, the outdoor unit elevated on a stand where winter defrost drainage demands it, condensate handled properly, and the thermostat configured so staging, backup lockouts, and defrost behave the way the engineering intended. Then we commission in both modes, heating and cooling, and record the readings.

Warning Signs for Heat Pump Installation
Catching these issues early helps you avoid costly problems and protect your property. Watch for these telltale signs that professional help is needed:
- Rooms run hot in summer and cold in winter on the existing equipment
- An aging AC and furnace you would rather replace with a single system
- You want quieter, more consistent comfort than your current system delivers
- High heating bills from electric baseboard, propane, or oil
- You are moving toward an all-electric home or adding solar panels
- Local utility rebates make a heat pump switch more affordable
- Your existing equipment needs refrigerant recharges or big repairs to keep running
- You want one system, one outdoor unit, and one maintenance schedule
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. At the first hint of a problem, reach out to Dunwoody HVAC at (470) 200-3365 for a fast inspection.

Why Professional Heat Pump Installation Matters
Heat pumps punish installation shortcuts more than any other residential system because they work both sides of the year. A charge that is slightly off hurts twice, in cooling efficiency all summer and heating capacity all winter. A balance point never calculated means electric backup strips quietly carrying the house at several times the operating cost while the homeowner wonders why the bills did not drop. A thermostat left on defaults can run backup heat when the compressor alone would do, or fight the defrost cycle. And an outdoor unit set flat on the ground in a real winter sits in its own refrozen defrost water until the coil is a block of ice.
We design and install to prevent every one of those problems. Loads are calculated for heating and cooling, equipment is selected for its actual capacity at your winter design temperature, backup heat is staged and locked out properly, the outdoor unit is raised for defrost drainage, and the charge is weighed and verified instead of guessed. Commissioning covers both modes, including a check of the reversing valve and a full defrost cycle. Refrigerant handling is federally regulated, and inverter equipment brings electronics that reward careful setup. Installed correctly, a heat pump gives your home the quietest, steadiest comfort available.
Our Heat Pump Installation Process
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's exactly how the heat pump installation process unfolds:
Two-Season Sizing
We size for summer and winter together, locate the balance point for local winter temperatures, and check that the electrical service and ductwork can support the new system.
System Design & Firm Quote
We match compressor staging to your climate, choose between electric strip and dual-fuel backup, and quote one firm installed price for the system your home really needs.
Careful, Verified Installation
We pressure-test and evacuate the line set to a verified vacuum, weigh in the charge, elevate the outdoor unit for winter defrost drainage, and set up the thermostat's staging and backup lockouts.
Heating & Cooling Startup
We test the system in both heating and cooling, confirm the reversing valve and a complete defrost cycle, record split, amp draw, and charge readings, and walk you through everything before we leave.

Taking preventive measures can help you avoid costly heating and cooling problems down the road. Put these technician-approved steps to work around your property:
- Keep an eye on winter bills; a sharp increase usually means the backup heat is running too much
- Book twice-yearly maintenance so charge and defrost stay verified in both modes
- Keep temperature settings steady so the backup strips are not needed to catch up
- Give the outdoor unit open space all year, free of drifts and overgrowth
- Light frost and an occasional defrost hiss are normal in winter, but solid ice calls for service
- Gently hose off the outdoor coil every spring before cooling season
- Change filters on schedule; low airflow hurts a heat pump in both seasons
DIY vs. Professional Heat Pump Installation
A homeowner can swap a filter with ease, but diagnosing capacitors, refrigerant charge, control boards, and error codes calls for the equipment and know-how only a pro brings. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Sizing | Cooling load only, winter ignored | Both loads calculated, balance point found |
| Backup Heat | Strips run whenever, bills soar | Staging and lockouts set for your climate |
| Refrigerant Charge | Guessed charge that hurts all year | Measured charge confirmed heating and cooling |
| Defrost | Unit flat on grade, ices itself in | Elevated, drained, cycle verified |
| Thermostat Setup | Factory settings left in place | Thermostat set for staging and backup |
| Commissioning | Checked in one mode only | Verified in both modes at startup |
