Heat pump repair and installation in Atlanta, GA covers diagnosing and fixing a system that moves heat rather than generating it, or replacing one that has reached the end of its useful life. A heat pump handles both heating and cooling through a single outdoor unit and air handler, making it a common choice in Atlanta’s climate, where winters are mild enough that a heat pump can carry the load most of the season without leaning heavily on backup heat.
Atlanta’s weather puts a specific kind of wear on these systems. Summers along the BeltLine corridor or in a renovated Virginia-Highland bungalow can run long and humid, keeping the outdoor unit working hard from April well into October. Then a hard cold snap arrives in January, and a system that coasted through a warm December is suddenly running at full demand. That swing is where problems surface.
The housing stock here adds another layer. Inman Park Craftsmans, mid-century ranches in Grant Park, newer townhomes near Ponce City Market, and high-rise condos in Midtown can all share the same street but have very different duct layouts, air handler locations, and electrical setups. The age and condition of what’s already in the home shapes every repair and every new installation.
All Purpose Heating and Air Conditioning has been doing this work in Atlanta for more than 35 years. Our crews are across the city on a daily basis. We know the neighborhoods, the housing types, and the specific demands this climate puts on heat pump equipment.
A heat pump gives you signals before it fails completely. Knowing what to look for saves you from a cold house on the wrong night.
Blowing cool air in heating mode. This is the most common complaint we hear. The system runs, air moves, but the house stays cold. The cause is usually a reversing valve that has stuck in cooling mode, a low refrigerant charge, or a refrigerant leak. None of those fix themselves.
Ice on the outdoor unit. Some frost in cold weather is normal. A unit encased in ice that does not clear during the defrost cycle is not. A failed defrost control board, a bad defrost sensor, or restricted airflow can all cause this. Atlanta’s occasional ice storms can accelerate the problem if the unit is not properly positioned or protected.
Auxiliary heat running constantly. Heat pumps in Atlanta rely on auxiliary or emergency heat strips during hard cold snaps, but that backup should kick in briefly, not run for hours at a time. Constant aux heat usually means the heat pump itself is not producing enough capacity, which points to a refrigerant issue, a failing compressor, or a reversing valve problem.
The system is past its expected service life. Industry guidelines generally put heat pump lifespan in a range of roughly fifteen to twenty years, though actual longevity depends on maintenance history, run time, and installation quality. Many of the older homes in Buckhead or the Old Fourth Ward are still running systems that were installed well before the current owners moved in. If your unit is approaching or past that range, repair costs and replacement costs need to be weighed honestly.
Every job starts with a real diagnosis. We do not guess and we do not replace parts hoping for the best. A technician checks the refrigerant charge, tests the reversing valve, inspects the defrost board and sensors, measures electrical draw at the compressor and capacitors, and looks at the air handler and blower motor. You get a clear picture of what is wrong before any work begins.
For a new installation, sizing comes first. Atlanta’s humidity load matters here. A unit sized only for temperature will struggle with moisture control in a long summer, and an oversized system will short-cycle, leaving the air clammy and wearing out the compressor faster. We size based on the actual home, including square footage, insulation, window area, and duct condition.
On a repair, the sequence typically runs from diagnosis to parts sourcing, then refrigerant recovery and recharge if needed, reversing valve or defrost component replacement, electrical checks, and a full startup test to confirm the system is moving through both heating and cooling cycles correctly.
On a replacement, we remove the old equipment, address any duct or electrical issues that the new system requires, install and connect the outdoor unit and air handler, pressure-test the refrigerant lines, charge the system to spec, and run a complete startup sequence before we leave.
What drives cost and timeline is straightforward. A repair on a single failed component is faster and less expensive than a full system replacement. Replacing only the outdoor unit when the air handler is old and mismatched can create efficiency and reliability problems, so that conversation happens upfront. System size, the condition of existing ductwork, and whether electrical service needs updating all affect the scope. Request your estimate to get a real number for your specific situation.
All Purpose Heating and Air Conditioning works across Atlanta and the surrounding metro. Whether you are in a Midtown condo, a bungalow in East Atlanta, or a newer build further out, we have crews running routes through these neighborhoods regularly.
If you want a broader look at everything we handle for Atlanta homeowners and commercial customers on the heating and cooling side, our Atlanta HVAC services page covers the full picture, from seasonal tune-ups to full system replacements.
For heat pump work specifically, including repair diagnostics, refrigerant service, defrost system repairs, and new installations, our heat pump services page walks through what each type of job involves and what to expect from the process.
Atlanta summers are long, and when the cooling side of your heat pump is not keeping up, that is its own urgent problem. Our Atlanta AC repair page covers the cooling-mode issues we see most often in this climate, including refrigerant leaks, capacitor failures, and airflow problems that show up after a hard summer of use.
We also serve Alpharetta, Conyers, Peachtree City, Newnan, and McDonough. Give us a call or request your estimate and we will get someone out to take a look.
