A heat pump is one of the best matches for our climate: it cools like a central AC all summer and reverses to heat the home through most of a North Georgia winter, using electricity efficiently instead of burning fuel. For many Cobb County homes it's the practical answer when both the AC and the heating are due for replacement.
The trade-off is that heat pumps lean on a backup heat source during hard freezes, and they're sensitive to correct refrigerant charge and airflow. We size the system with a load calculation, set up the backup or dual-fuel strategy properly, and service existing heat pumps so they defrost, stage, and switch modes the way they should.
Signs Your Heat Pump Needs Service or Replacement
Heat pumps show trouble in both heating and cooling modes. Call us if you notice:
- Weak cooling in summer or weak heating in winter
- The outdoor unit ices over and won't defrost properly
- Auxiliary or 'emergency heat' running far more than it should
- The system won't switch between heating and cooling modes
- Short cycling or the outdoor fan not starting
- Higher electric bills without a comfort improvement
- Loud grinding, buzzing, or a burning smell at the unit
How Our Heat Pump Service Works
Whether it's a repair or a full install, you get a clear diagnosis and a written price first.
- 1
Assessment & diagnosis
For repairs, we test refrigerant charge, the reversing valve, defrost control, capacitors, and airflow. For installs, we run a load calculation and evaluate ductwork and electrical.
- 2
Backup heat & dual-fuel planning
We set up the balance point and staging so the heat pump does the work in mild weather and the electric strips or gas backup engage only when it's genuinely cold — the key to keeping bills reasonable.
- 3
Written options & approval
We show you the readings or the equipment tiers, explain the trade-offs, and give a written price. Nothing chargeable proceeds until you approve.
- 4
Install or repair, then verify
We complete the work, verify heating and cooling performance, confirm the defrost cycle and mode switching, register any new-equipment warranty, and document the job.
Why Heat Pumps Fit North Georgia
Our winters spend far more time in the 30s and 40s than in a deep freeze, and that's exactly the range where a heat pump is most efficient — moving heat instead of generating it. Across a full year, running one system for both heating and cooling often costs less than a separate furnace and AC.
The honest caveat is the cold snap. When temperatures drop into the teens, the heat pump needs help, which is why we set the backup heat and balance point carefully instead of leaving the strips to run whenever they please.
Dual-Fuel: The Best of Both
If you already have gas service, a dual-fuel setup pairs a heat pump with a gas furnace. The heat pump carries the mild majority of the season efficiently, and the furnace takes over automatically when it gets cold enough that gas heat is the better value.
We configure the switchover point so the changeover is automatic and sensible. For homes without gas, a well-sized heat pump with properly staged electric backup does the job — and we'll tell you which path fits your home.
What Heat Pump Work Costs in Kennesaw
A new heat pump system lands in the same neighborhood as other full system replacements — Atlanta-area guides put comparable projects around $5,000–$12,500 depending on size, efficiency, and backup setup. Repairs track closer to AC repair pricing, commonly $150–$650. These are context ranges, not quotes.
Because a heat pump handles both seasons, the sizing and backup-heat decisions matter more than with a single-purpose unit. We quote after a proper assessment and lay the numbers out clearly, including any manufacturer or utility rebates available at install time.
What affects your price:
- System capacity, SEER2/HSPF2 efficiency, and staging
- Backup heat type — electric strips versus dual-fuel gas
- Ductwork condition and any electrical upgrades needed
- For repairs, the failed component and refrigerant involved
- Available manufacturer or Georgia utility rebates
