5 Tell-Tale Signs Your AC Is FailingSummer is heating up fast here in West Volusia County, FL. How is your air conditioner holding up?

In our hot, humid climate, you won’t make it very long without a functioning AC unit. But how can you tell if yours is about to break down?

Watch for these five tell-tale signs your AC is failing. If you spot any, call a technician for residential HVAC services as soon as possible.

Warm Air or Minimal Air Flow Coming from the Vents

When your air conditioner runs, you should feel a steady, refreshingly cold breeze coming from every supply register. If the air is warm or flows weakly from the vents, you’ve got a problem.

Warm air could be caused by a refrigerant leak or blockage in the refrigerant line. This isn’t something that can work itself out—the problem will only become more severe if you continue to operate the air conditioner.

Poor airflow could signal a problem with the blower fan, or the AC compressor could be on its last leg. There might also be a blockage in the ductwork. Either way, you should call an AC technician to take a look.

Loud Noises or Strange Smells

After years of relying on the same AC unit, you should be very familiar with how it sounds by now. A sudden eruption of squealing, grinding, scraping, bumping, or banging almost certainly means something is wrong. From a loose part to a bad motor, it’s essential to address the problem before it gets any worse. Turn off the AC immediately and call a professional for help.

Similarly, strange smells are also a cause for concern. A musty smell could point to mold in the system, while a pungent burning order might mean the wiring insulation has burned out. Have a professional diagnose the problem before you run the AC again.

Short Cycling

Typically, your air conditioner should run for several minutes every cycle. This gives it a chance to not only cool off the house but to remove humidity as well. Short cycling can be caused by a failing compressor, clogged air filter, or low refrigerant charge. Don’t stand around guessing what’s wrong—call a technician for a diagnosis and repair.

Home Comfort Problems

Do some rooms feel warmer than others? Something could be affecting the airflow. Is it too humid in your home? Your air conditioner could be short cycling. In Florida’s hot climate, you can’t afford to have an air conditioner that only does half its job. The problem might be repairable, or your AC might be failing for the final time. The only way to find out is to call an HVAC technician.

High Utility Costs

Even if you have automatic payments set up on your electricity bills, you should always assess them for unexpected changes. Sometimes, a skyrocketing bill is the result of an error on the utility company’s end. But most of the time, it’s a sign that your air conditioner is failing.

Call your utility provider to find out if a higher-than-usual charge was a mistake. If not, it could mean you have a broken thermostat switch, or a sudden leak has sprung up in the ductwork. Your air conditioner might also simply be reaching the end of its lifespan. This is a common culprit of high energy bills, especially if your unit is over 10 years old.
