Styles & brands we work with
AC Not Blowing Cold Air in Marietta
AC not blowing cold air in Marietta is the single most common call we get, and it usually comes down to one of a handful of causes: a failed capacitor, low refrigerant, a clogged condenser coil, or a blower motor that’s given up. The fix ranges from $150 for a simple capacitor swap to $650 for a compressor-side repair, parts and labor included.
Capacitor Failure: The Five-Minute Culprit
The capacitor is the small cylinder that gives your compressor and fan motor the jolt they need to start. In Marietta’s long, muggy summers, capacitors work harder and fail faster, especially on units that cycle constantly through July and August. A weak capacitor often still lets the fan spin, but the air comes out warm. We test this first, because it’s cheap to replace and expensive to ignore, a dead capacitor left running can cook the compressor.
Field Vignette: A 58°F Save Off Whitlock Avenue
Last July, our tech rolled up to a 1972 split-level off Whitlock Avenue where the condenser fan spun but the air blew warm. The culprit was a weak dual-run capacitor, a five-minute test caught it before the compressor cooked. We replaced it, checked the refrigerant charge and static pressure, and had the Trane unit blowing 58°F air within the hour. That’s the difference between a $250 repair and a $4,000 compressor replacement.
Refrigerant Recharge: When Low Charge Means Frozen Lines
A refrigerant recharge, that’s refilling the fluid that moves heat out of your home, is needed when a system has leaked charge over time. Marietta’s 1960s through 1980s ranch homes often still run R-22 systems, and those aging evaporator coils corrode and leak. If you see ice on the copper lines or hear hissing at the indoor unit, shut it down and call us. A proper charge adjustment runs $200 to $500, but we always leak-test first. Adding refrigerant to a leaking system is just buying time.
AC Service in Marietta
AC service in Marietta means more than a seasonal tune-up. It’s the proactive work that keeps your system from failing during the first heat wave or the surprise cold snap that catches Cobb County off guard in January. A full AC service and system check runs $80 to $200, and it includes the checks that matter most in this climate: coil condition, capacitor strength, refrigerant level, and airflow measurement.
Pollen and Coil Cleaning: Marietta’s Springtime Tax
Oak and pine pollen from Marietta’s spring bloom cakes outdoor condenser coils. By June, that layer of yellow-green film is dropping SEER2 efficiency and tripping high-head-pressure switches. A condenser coil cleaning runs $120 to $250 and should happen every spring here. Skipping it can cost you 10 to 15 percent in efficiency, and in August, that’s real money on a Georgia Power bill.
The “Marietta Split”: When 1970s Ductwork Meets a Cold Snap
Here’s something you won’t read on a national HVAC site. Marietta’s inland position, 300-plus miles from the Gulf, means winter cold snaps hit harder than in nearby Atlanta suburbs. Heat pumps in 1970s split-levels often run through undersized ductwork, and when a surprise freeze drops temperatures into the teens, those systems switch to emergency heat and the blower motors choke against high static pressure. The result is warm air trickling out of vents while the outdoor unit runs full tilt. If you’ve fired your heat pump on a cold night and heard the blower laboring, that’s the Marietta split, and it’s a familiar sight for local techs. We check static pressure during AC service calls, because fixing the fan motor before it fails is far cheaper than replacing a burnt-out ECM blower.
Common AC Repair Problems We See in Marietta Homes
- Pollen-clogged condenser coils. Marietta’s oak and pine canopy is beautiful in April and brutal on AC equipment by June. A clogged coil trips high-pressure switches and forces the compressor to work harder, cutting years off its life.
- R-22 refrigerant loss in aging ranch homes. Homes built from the 1960s through the 1980s often still run R-22 systems. The evaporator coils in those units corrode, leak charge, and cause frozen lines and no-cool calls. We can still service these systems and recharge them where supplies allow.
- Blower motor failure from undersized ductwork. Split-level homes in Marietta frequently have ductwork sized for a smaller system than what’s installed. The blower works against that resistance every cycle, and eventually the motor burns out. It’s a predictable failure we see often.
- Thermostat drift and calibration issues. Marietta’s temperature swings between humid summers and freezing winter mornings cause cheap thermostats to drift. A calibration issue can make your system short-cycle or run constantly, and it’s a $100 to $200 fix that looks like a much bigger problem.

FAQs About AC Repair in Marietta
Marietta’s spring pollen bloom, mostly from oak and pine trees, coats outdoor condenser coils and forces your system to work harder to shed heat. By late May, that layer of pollen can cut efficiency by 10 to 15 percent and trip high-head-pressure switches. A coil cleaning in April or early May is the most cost-effective preventive step for Marietta homeowners. Call (478) 662-5175 and we’ll clean yours for $120 to $250.
Yes, and it’s the Marietta split. Heat pumps in 1970s split-levels often run against undersized ductwork, and when winter cold snaps hit, the blower motor strains against high static pressure. We check static pressure and blower motor health during every service call, because catching this before the motor burns out is a $200 fix instead of an $800 replacement. If your system switches to emergency heat and still struggles, call us, we’ll diagnose it properly.
In Marietta’s long, humid summers, capacitors work harder and degrade faster than in milder climates. We recommend testing the capacitor during a spring AC service visit every year, and then again if you notice the fan spinning but the air blowing warm. Testing takes minutes. Replacing a failing capacitor costs $150 to $350. Ignoring it can destroy the compressor, which is a $3,500 to $7,500 system replacement.
Yes. Pollen that coats your outdoor coil isn’t just an efficiency problem, it also recirculates through return ducts and into the home when the system runs. Homes in Marietta with older, leaky ductwork pull pollen from crawl spaces and attics into the air stream. A coil cleaning plus checking your filter setup and duct connections addresses this. It’s part of what we look at during AC service.
Yes, we can. R-22 is no longer manufactured, but reclaimed and limited supplies remain available, and many Marietta homes from the 1960s through 1980s still run on R-22. We’ll leak-test the system first, and if the leak is in the evaporator coil, we’ll give you a straight answer on whether repair or replacement makes more sense. A refrigerant charge adjustment runs $200 to $500. Call (478) 662-5175 for a free estimate.
