AC Not Cooling in Savannah GA
Your AC is running but the house won't cool down in the Savannah heat? Coastline Heating & Air finds the real cause fast and gets you cold air back — same-day, 7 days a week. Honest diagnostics, flat-rate pricing, no upsells.
Why Is My AC Not Cooling in Savannah GA?
When your air conditioner is running but the house just won't cool down, it's almost always one of a handful of causes — and Savannah's brutal summer heat and coastal humidity make every one of them worse. An AC that keeps up fine in May can fall behind fast once the temperature and dew point climb in July. Here are the most common reasons we find an AC not cooling in Savannah GA:
- Low refrigerant / refrigerant leak. The #1 cause of "running but not cooling." Without the right charge, the system can't pull heat out of your home. Leaks need to be found and sealed — just "topping off" is a temporary band-aid.
- Frozen evaporator coil. Low airflow or low refrigerant can ice the indoor coil solid. You'll feel weak airflow and warm air, and may see ice on the copper lines. Shut the system off (fan ON) to thaw and call us.
- Dirty condenser coil. Savannah's pollen, salt air, and grass clippings clog the outdoor unit so it can't dump heat. Coastal salt also corrodes coils faster than inland — a real factor near the marshes and rivers.
- Failed capacitor or contactor. Cheap parts that fail in the heat and stop the compressor or fan from starting. Common and fast to fix.
- Compressor problems. The heart of the system. A failing compressor means little or no cooling and needs professional diagnosis.
- Thermostat or wiring fault. A miscalibrated or failing thermostat tells the system to do the wrong thing.
- Clogged condensate drain. A backed-up drain trips the safety float and shuts cooling down in our high humidity.
- Undersized or aging system. A unit that's too small — or 12-15+ years old — simply can't keep up with a Savannah heat wave.
Troubleshooting: Try This Before You Call
A few quick checks can occasionally get your cooling back — or at least help our tech move faster:
- Set the thermostat to COOL and the fan to AUTO, a few degrees below room temperature.
- Check the breaker. Reset the AC breaker once if it's tripped. If it trips again, stop — that's a call for a tech, not a re-reset.
- Change a dirty filter. A clogged filter chokes airflow and is a leading cause of warm air and frozen coils.
- Make sure every supply and return vent is open and unblocked.
- Look at the outdoor unit. Is the fan spinning? Clear grass, leaves, and debris from around it.
- See ice on the refrigerant lines or coil? Turn cooling OFF and the fan ON to thaw it, then call us — running a frozen system causes damage.
If none of that brings the cold air back, the problem is internal. That's where we come in — same-day, with the parts on the truck to fix most failures on the first visit.

Frequently Asked Questions
Real answers to what Coastal Georgia homeowners ask us most.
Why is my AC running but not cooling in Savannah GA?
The most common reasons an AC runs but won't cool in Savannah are low refrigerant from a leak, a frozen evaporator coil, a dirty condenser coil (worsened by coastal salt and pollen), a failed capacitor, or a struggling compressor. Savannah's heat and humidity expose a marginal system fast. A proper diagnostic pinpoints the exact cause — Coastline's is $89 and rolls into the repair when you book same-day. Call (912) 445-1233.
How much does it cost to fix an AC that's not cooling in Savannah?
AC repair in Savannah typically runs $150–$450 for minor work (capacitor, contactor, thermostat), $450–$1,200 for mid-range work (refrigerant leak find and recharge, blower motor), and $1,200–$3,500 for major work like a compressor or evaporator coil replacement. The $89 diagnostic rolls into the repair total when you book same-day, and you get the price before any work starts.
Can you fix my AC the same day in Savannah?
Yes — most same-day Savannah requests get a technician on site within a few hours, and we stock the common parts (capacitors, contactors, refrigerant, motors) on the truck to fix the majority of no-cool calls on the first visit. For after-hours no-cool emergencies, Coastline runs 24/7 service across Savannah and Chatham County.
My AC is blowing warm air in Savannah — what's wrong?
Warm air from the vents usually points to low refrigerant, a frozen coil, a tripped outdoor unit, or a compressor that isn't running. Check that the thermostat is set to COOL, the filter is clean, and the outdoor fan is spinning. If you see ice on the lines, shut cooling off and run the fan to thaw it, then call (912) 445-1233 for fast diagnosis.
Why is my AC freezing up in the Savannah humidity?
A frozen evaporator coil is caused by restricted airflow (dirty filter, closed vents, failing blower) or low refrigerant. Savannah's high humidity makes icing more likely once airflow drops. Turn the system to OFF with the fan ON to thaw the coil, replace a dirty filter, and call us — running a frozen system can damage the compressor.
Does salt air near the coast affect my AC in Savannah?
Yes. Homes near the marshes, rivers, and islands around Savannah see faster corrosion on outdoor condenser coils from salt in the air. Corroded coils lose efficiency and can develop refrigerant leaks, which shows up as an AC that runs but won't cool. Regular maintenance — and a coil rinse — slows it down considerably.
Should I repair or replace an AC that won't cool?
If your system is under about 10 years old and the repair is straightforward (capacitor, contactor, leak, motor), repair is almost always the right call. If it's 12-15+ years old, uses old R-22 refrigerant, and needs a compressor or coil, replacement usually makes more financial sense. Coastline gives you an honest repair-vs-replace recommendation with no pressure.
Do you offer AC maintenance to prevent no-cool breakdowns in Savannah?
Yes — the Coastline Comfort Club includes two precision tune-ups a year, a 21-point inspection, priority dispatch, and 10% off any repair for $24/month. Bi-annual maintenance catches weak capacitors, low refrigerant, and dirty coils before they leave you without cooling in a Savannah heat wave — the single best way to avoid a no-cool emergency.
