If you live in Atlanta and your AC stops working, you need it fixed immediately, a need that most HVAC services can oblige. But it’s also possible you could fix the problem yourself, saving time and money. Below, we cover some common AC problems and whether you should fix them yourself, or call an air conditioning repair Atlanta HVAC service.

1. Wrong setting on thermostat

It’s surprising how often a wrongly set thermostat is cause of poor cooling. If your air conditioner isn’t kicking on, check to see if your thermostat is accidentally set on “heat” or “off.” If it is, switch it to “cool” and your problem is solved.

2. Equipment isn’t receiving electricity

To see of your AC equipment is receiving electricity, check your electrical panel for blown fuses or tripped switches, as well as service switches and controls that regulate power to your AC equipment, including your outside compressor. Replacing a blown fuse, resetting a tripped switch, or resetting service switches and/or controls may start your AC. If it doesn’t, call an HVAC service.

3. Outside compressor isn’t working properly

If your compressor isn’t working, or is working ineffectively, you may solve the problem by checking your electrical panel or resetting the compressor’s power switch. If these measures don’t work, your compressor may have a clogged condensing coil. You can clean a clogged condensing coil by referring to your compressor’s maintenance guide. In most cases, however, clogged coils are cleaned by an HVAC service.

4. Air handler isn’t working properly

If your handler isn’t working, or is working ineffectively, you may solve the problem by checking your electrical panel, resetting the handler’s power switches (there may be more than one), or making sure its blower compartment door is securely in place. If these measures don’t work, you handler may have a clogged cooling coil or evaporator coil. You can perform coil maintenance by referring to your handler’s maintenance manual. In most cases, however, clogged coils are cleaned by an HVAC service.

5. Clogged Filter

An air filter removes dust, pollen, and other unwanted debris from airflow as it cycles through your system. Over months, this debris can accumulate and block airflow, resulting in poor cooling effect. In most instances, you can change a clogged filter by referring to your handler’s maintenance manual, or by accessing it from a large intake vent located on your ceiling (usually in homes with the air handler in the attic).

6. Registers in closed position

Some people close their registers for the winter if they have radiator heat, and then forget to open them in the spring. Before calling an air conditioning repair service to assess your problem, check to see if your registers are open.
