These are the problems behind most local repair calls. Only a technician can confirm the cause. - **Blowing warm air**: Often a failed capacitor, a stopped outdoor fan, low refrigerant from a leak, or a clogged filter choking airflow. - **Not turning on**: Thermostat settings or batteries, a tripped breaker, a condensate safety switch, or a failed contactor. - **Frozen coil or iced lines**: Usually restricted airflow or low refrigerant. Turn cooling off and let it thaw before the technician arrives. - **Water around the indoor unit**: Humid Georgia air means a lot of condensate. A clogged drain line backs it up into the pan or onto the floor. ## When to call an HVAC contractor in Marietta - The breaker trips again after one reset - The outdoor unit hums but the fan doesn't spin - Ice forms on the lines or comes back after thawing - Water keeps collecting at the air handler or stains a ceiling - Burning smell, grinding, or banging - Any refrigerant, electrical, or gas work ## Georgia climate and local considerations in Marietta **Cooling is a long season here.** Marietta sits in metro Atlanta's humid subtropical climate, where air conditioners work through long summers and also have to pull moisture out of the air. More than 90% of Georgia households use central air conditioning ([U.S. EIA](https://www.eia.gov/consumption/residential/reports/2009/state_briefs/pdf/ga.pdf)). A system that runs constantly but leaves the house feeling sticky may be oversized, low on refrigerant, or struggling with airflow. **Many Marietta homes buy power from the city.** Marietta Power is a city-owned electric utility created in 1906 that serves more than 45,000 electric customers in Marietta and parts of Cobb County ([City of Marietta](https://mariettaga.gov/827/About-Us)). It held rates flat for 2026, and Georgia's Public Service Commission survey ranks it the second-most affordable residential provider in the state ([Cobb County Courier](https://cobbcountycourier.com/2026/02/no-electric-rate-increase-for-marietta-power-customers-in-2026/)). If your summer bill jumps while rates are flat, that points to your equipment working harder, not a rate change. **Heating matters too.** Georgia homes split almost evenly between natural gas and electricity as their main heating fuel (U.S. EIA), so a Marietta home may have a gas furnace with a separate AC, or an electric heat pump that handles both. That affects what a technician checks and what a replacement involves. **Check the license.** Georgia requires HVAC contractors to hold a Conditioned Air Contractor license from the State Construction Industry Licensing Board, overseen by the Georgia Secretary of State. You can look up a license on the Secretary of State's verification site before work starts. Replacements generally need a permit; ask the contractor who pulls it. ## Repair or replace your AC in Marietta? There's no single age or dollar figure that decides it, but these factors matter most: how old the system is, what failed (a capacitor is a small repair; a compressor or coil is a major one), the repair quote, how efficient the system is, whether it was sized correctly for the house, and its overall condition. Systems that use R-22 refrigerant deserve a closer look. New R-22 hasn't been produced since 2020, and the EPA notes servicing costs may rise as supplies shrink. A leak in an older R-22 system is often where replacement starts to make more sense. ## HVAC questions from Marietta **How much does AC repair cost in Marietta?** There's no Marietta-specific price survey. HomeAdvisor's 2026 national data puts most AC repairs between $172 and $664, averaging about $417, plus a diagnostic fee of $75 to $200. Evenings and weekends usually cost more. **My Marietta Power bill went up but rates didn't. Is my AC the problem?** It may be. Marietta Power held rates flat for 2026, so a big jump usually means more usage. A dirty filter or coil, low refrigerant, leaky ducts, or an aging system all make an AC run longer. A technician can check refrigerant levels, airflow, and the coils. **Why is there water around my indoor AC unit?** Air conditioners remove a lot of moisture in Georgia's humid summers. If the condensate drain line clogs, water backs up into the pan or onto the floor, and a safety switch may shut the system off. Turn the system off and call a technician. **How do I check an HVAC contractor's license in Georgia?** Georgia licenses HVAC contractors as Conditioned Air Contractors through the State Construction Industry Licensing Board. Look up the contractor's name or license number on the Georgia Secretary of State's license verification site. **Is Georgia HVAC Repair a Marietta HVAC company?** No. Georgia HVAC Repair is an independent referral service.
