Five months of heat, then storms on top of it

Mableton gets five months of real cooling load, May through September, with summer afternoons averaging 88°F. Your air conditioner is running most of that stretch, and the outdoor unit sits outside taking the heat the whole time.

Cobb County has also logged 70 damaging wind events and 22 hail events over the past ten years, with hail up to 1.75 inches. Wind can tear at the fins on your outdoor unit or throw debris into it, and hail that size can dent the cabinet or bend the coil fins enough to choke off airflow. If your air conditioner started struggling right after a storm, that is often why.

A new air conditioner would cut about $50 a year off cooling for a typical Cobb County home.

  • A new one at the federal minimum, 14.3 SEER2$340 a year
  • An older air conditioner$390 a year

Estimates for a typical Cobb County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Georgia fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when a part like a capacitor or contactor has failed.

Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.

Georgia requires HVAC contractors to hold a state license.

The State Construction Industry Licensing Board issues that license, and it belongs to the contractor, not to any single job. It covers the contractor's standing to do this work at all, not this particular repair.

For a repair on your air conditioner, that license is the thing accountable for the work. If the repair means opening the refrigerant lines, whoever does that also has to hold EPA Section 608 certification, a federal requirement that applies in every state on top of Georgia's license.

Why is my AC not blowing cold air?
The most common cause is a dirty air filter choking off airflow across the coil. When air can't move past the filter, the coil can freeze up and the air coming out of your vents turns warm. Low refrigerant from a leak causes the same thing, and that's not something you can fix by topping it off since it will just leak out again. A contractor needs to check airflow and refrigerant charge to find out which one you're dealing with.
Why is my AC leaking water?
Water around your unit usually means the condensate drain line is clogged. Algae and dirt build up inside that line over a cooling season and block the path water normally takes to drain outside, so it backs up and drips out where you can see it. A frozen coil that's thawing can also leave water behind once it melts. Either way, a contractor can clear the line or find out why the coil froze in the first place.
Why won't my AC turn on?
Start with your thermostat batteries and your breaker panel, since a dead battery or a tripped breaker will stop the system cold before anything else is wrong. If those check out, the capacitor that starts the outdoor unit's motor may have failed, which is a common reason a system goes quiet. With summer afternoons here averaging 88°F, a unit that won't start is worth getting looked at quickly. A contractor can test the capacitor and the electrical components to find the actual cause.
