When summer hits Georgia, the heat can be overwhelming. Your air conditioner becomes the most important system in your home, keeping you and your family cool and comfortable. But like any piece of equipment, your AC can break down when you least expect it.

At Comfort Guardians, we specialize in AC repair in Lawrenceville, GA, and we know that catching problems early is the best way to save money and avoid a total system failure. That’s why we’ve put together this guide to help you recognize the most common warning signs that your AC needs professional repair.

1. Your AC Is Blowing Warm Air

One of the most obvious signs of a problem is when your air conditioner runs but only produces warm air. This could be caused by:

• Low refrigerant levels

• A dirty or clogged air filter

• A failing compressor

If you notice warm air coming from your vents, it’s time to call a licensed HVAC technician. Ignoring the problem can strain your system and lead to higher repair costs.

2. Weak or Inconsistent Airflow

If the air coming from your vents feels weak—or some rooms are cooler than others—your AC may be struggling to circulate air properly. Common causes include:

• Blocked or leaky ductwork

• A broken blower motor

• Frozen evaporator coils

Poor airflow doesn’t just make your home uncomfortable; it also forces your system to work harder, driving up your energy bills.

3. Strange Noises or Odd Odors

Your air conditioner should run quietly. If you hear banging, grinding, squealing, or buzzing noises, it could be a sign of loose or broken components.

Unpleasant odors are also a red flag. Musty smells may indicate mold or mildew in your ductwork, while a burning smell could point to electrical problems. Both should be addressed immediately to avoid bigger issues.

4. Rising Energy Bills

Are your utility bills higher than usual—even though you’re running your AC the same amount? An inefficient system may be to blame. Issues like dirty coils, worn-out parts, or refrigerant leaks can make your air conditioner work harder to cool your home, wasting energy in the process.

A professional tune-up and repair can restore efficiency, lowering both your bills and your stress.

5. Frequent Cycling or Constant Running

Does your AC turn on and off more than usual? Or maybe it seems like it never stops running? Both can signal a serious issue. Possible causes include:

• A malfunctioning thermostat

• Low refrigerant levels

• Improper system sizing

Not only does this wear down your system, but it can also lead to premature failure if ignored.

Prevent Costly Breakdowns with Preventative Care

While repairs are sometimes unavoidable, scheduling regular AC maintenance can dramatically reduce the risk of unexpected breakdowns. Seasonal tune-ups help keep your system clean, efficient, and reliable—so you can stay comfortable all summer long.
