Late spring in Georgia is when air-source heat pumps start working hard again.
After a mild heating season, your heat pump switches into cooling mode and suddenly has to deal with Atlanta humidity, pollen, dirty coils, clogged filters, afternoon thunderstorms, and longer run times. If your system is running but not cooling, blowing warm air, freezing up, short cycling, or making strange noises, now is the time to schedule service before the first major summer heat wave.
EcoMech provides air conditioning and HVAC service for Atlanta, surrounding suburbs, and communities across Georgia. EcoMech’s AC service page says their trucks are stocked for cooling repairs and recommends calling or texting 678-855-8140 for air conditioning repair needs.

Quick Answer: Why Is My Heat Pump Struggling in Georgia Right Now?
At this point in the season, the most common air-source heat pump issues in Atlanta and Georgia are:
- Dirty air filters from spring pollen
- Dirty outdoor coils covered in pollen, leaves, and grass clippings
- Low refrigerant or refrigerant leaks
- Frozen indoor coils caused by airflow or refrigerant problems
- Clogged condensate drains from heavy humidity
- Electrical issues after storms or long off-cycles
- Thermostat or control problems during the heating-to-cooling transition
Atlanta’s average daily high temperatures rise through May from about 76°F to 83°F, which makes late spring the start of real cooling demand for local HVAC systems.
- Dirty Air Filters From Georgia Pollen
Spring pollen in Atlanta can be brutal, and your HVAC filter catches more than you think. When the filter gets packed with dust, pollen, pet hair, and debris, your heat pump cannot move enough air across the indoor coil.
That can cause:
- Weak airflow
- Longer run times
- Uneven cooling
- Higher utility bills
- Frozen indoor coils
- Warm air from vents
ENERGY STAR recommends checking central AC and heat pump filters monthly, noting that dirty filters increase energy costs and can damage equipment.
What you can do
Check your filter. If it looks gray, clogged, bowed, or dusty, replace it with the correct size and rating.
What not to do
Do not run the system for days with a clogged filter. Poor airflow can turn a simple maintenance issue into a frozen coil or repair call.
When to call EcoMech
If the filter is clean but airflow is still weak, call (678) 855-8140. The issue may be the blower motor, ductwork, evaporator coil, or refrigerant level.
- Dirty Outdoor Coil After Spring Debris
Your outdoor heat pump coil has one major job in cooling season: release heat from inside your home.
If the outdoor coil is covered in pollen, dirt, mulch dust, leaves, grass clippings, or cottonwood, the system cannot reject heat efficiently. The heat pump may run constantly and still leave the house warm.
ENERGY STAR specifically recommends cleaning evaporator and condenser coils because dirty coils reduce cooling ability, increase run time, raise energy costs, and shorten equipment life.
What you can do
Clear leaves, pine straw, weeds, and debris around the outdoor unit. Keep shrubs and landscaping from crowding the system.
What not to do
Do not pressure wash the coil. High pressure can bend fins and damage the unit.
When to call EcoMech
If your heat pump is running all afternoon but the temperature is not dropping, schedule service. EcoMech can clean the coil properly and check refrigerant, airflow, and electrical performance.
- Low Refrigerant or Refrigerant Leak
Your heat pump should not “use up” refrigerant. If refrigerant is low, there may be a leak or another sealed-system issue.
Signs of low refrigerant include:
- Warm air from vents
- Ice on refrigerant lines
- Frozen indoor coil
- Long cooling cycles
- Hissing or bubbling sounds
- Higher electric bills
- Poor humidity control
ENERGY STAR notes that too much or too little refrigerant reduces efficiency, increases energy costs, and can reduce equipment life.
What you can do
Look for ice on the copper refrigerant line, listen for unusual sounds, and note whether the system is cooling less than usual.
What not to do
Do not use DIY refrigerant products or ask for a quick “top-off” without leak diagnosis. Refrigerant issues require proper testing.
When to call EcoMech
Call EcoMech at (678) 855-8140 if your heat pump is blowing warm air, freezing up, or struggling to hold temperature.
- Frozen Indoor Coil
A frozen coil is one of the most common “my heat pump is running but not cooling” problems.
A frozen indoor coil can happen because of:
- Dirty filter
- Low airflow
- Dirty evaporator coil
- Low refrigerant
- Blower motor issue
- Duct restriction
- Thermostat set too low for current conditions
As the coil freezes, airflow drops even more. Eventually, the system may blow little to no air.
What you can do
Turn the system off and let it thaw. Check the air filter. Look for water around the indoor unit as ice melts.
What not to do
Do not chip ice off the coil. Do not keep running the system while frozen.
When to call EcoMech
A frozen coil is a symptom, not the root cause. EcoMech can test airflow, refrigerant charge, blower operation, and coil condition to identify the real problem.
Frozen heat pump? Call EcoMech at (678) 855-8140.
- Clogged Condensate Drain From Georgia Humidity
In cooling mode, your heat pump also removes humidity from the air. That moisture has to drain away through the condensate system.
Georgia humidity can make condensate drains work hard. If the drain line clogs with algae, sludge, debris, or buildup, you may notice:
- Water around the indoor unit
- Musty smells
- System shutoff
- Wet ceiling or flooring near the air handler
- Float switch trip
- High indoor humidity
This is a high-priority repair because water damage can happen quickly.
What you can do
Look for water near the indoor unit or drain pan. Check whether the system has shut off unexpectedly.
What not to do
Do not bypass the float switch. That safety device is there to help prevent water damage.
When to call EcoMech
If your heat pump shuts off and you see water near the unit, call (678) 855-8140 or email service@ecomech.net.
- Electrical Problems After Storms or Long Run Times
Late spring and summer in Georgia bring thunderstorms, power flickers, high demand, and longer HVAC run times. That can expose weak electrical components.
Common heat pump electrical problems include:
- Failed capacitor
- Bad contactor
- Condenser fan motor issue
- Loose electrical connection
- Tripped breaker
- Control board issue
- Compressor starting problem
EcoMech lists common AC repair work including blower motors, condenser fan motors, refrigerant leak repairs, and other cooling system repairs.
What you can do
Check the breaker one time. Make sure the thermostat is set to Cool.
What not to do
Do not keep resetting a breaker that trips repeatedly. Do not open electrical panels or reach into the outdoor unit.
When to call EcoMech
If the outdoor unit hums, clicks, starts and stops, or will not come on, schedule service immediately.
- Thermostat and Mode-Switching Problems
During Georgia’s spring-to-summer transition, homeowners may switch between Heat, Cool, Auto, and Emergency Heat. Sometimes the thermostat setting is the problem.
Common thermostat-related issues include:
- System set to Heat instead of Cool
- Fan set to On instead of Auto
- Dead batteries
- Incorrect schedule
- Bad temperature reading
- Loose thermostat wiring
- Communication problem on newer systems
What you can do
Set the thermostat to Cool, lower the setpoint a few degrees, and set the fan to Auto.
What not to do
Do not start removing thermostat wires unless you are trained. Wiring mistakes can cause control issues.
When to call EcoMech
If the thermostat is blank, inaccurate, short cycling, or not communicating with the equipment, EcoMech can diagnose the system.
- Poor Humidity Control
In Atlanta, comfort is not just about temperature. A home can feel hot and sticky even when the thermostat says 74°F.
Poor humidity control may point to:
- Oversized equipment
- Short cycling
- Dirty coil
- Low refrigerant
- Poor airflow
- Leaky ducts
- Thermostat or control settings
- Drainage problems
A properly operating heat pump should cool the air and remove moisture. If the home feels clammy, the system may need service before summer demand gets worse.
When to call EcoMech
If your heat pump cools the air but the house still feels humid, call (678) 855-8140 for diagnostics.
- Weak Airflow or Hot Rooms Upstairs
Many Atlanta homes deal with uneven cooling once temperatures climb.
Common causes include:
- Dirty filter
- Blower issue
- Duct leaks
- Poor duct design
- Closed dampers
- Undersized return air
- Zoning problem
- Attic heat gain
EcoMech’s site highlights HVAC engineers and duct designers for Atlanta homes and commercial projects, which matters when airflow—not just equipment—is the real issue.
What you can do
Make sure vents and returns are open and not blocked by furniture.
What not to do
Do not close a large number of vents to force air to one room. That can increase system pressure and make performance worse.
When to call EcoMech
If some rooms are hot while others are comfortable, EcoMech can inspect the full system: equipment, airflow, ductwork, and controls.
