Weather in Florida is pretty hot nearly all year round, so it’s important for your air conditioning system to be functioning properly and working efficiently. It’s easy to come to expect that cool air will start blowing when you turn it on, but what happens when hot air starts filling your home? Or what do you do when you come home to a hot house that you were expecting to be cool?

At Modern Services, our team of AC specialists knows exactly what to do. Instead of calling us for air conditioning repair after your system has already stopped working, it’s best to know the signs that it may need repair before it breaks — and you’re left dealing with a hot house and a frustrated family. Even though it may take an expert to actually repair the AC unit, the signs are fairly easy to recognize once you know what they are. If you have any questions or need to schedule an emergency AC repair, give us a call today! We provide service throughout western Florida and we’re always just a call away.

7 Top Signs Your Air Conditioning System Needs Repair

It’s Blowing Hot Air

This one may be fairly obvious, but if you put your hand over a vent and you feel warm air, it’s a very good indicator that you need to call a technician. First, take a look at your thermostat to make sure it’s set to the cooling mode. Then try lowering the setting to below the existing temperature in the home. If the air is still warm, there may be an issue with the compressor, or airflow may be restricted. Don’t wait too long to call for AC repair as this could have an impact on your electricity bills.

Insufficient Airflow

Without proper airflow, the entire system won’t be able to function properly. This could be due to a blockage in the ductwork, or there may be a clogged filter, a broken motor, and even something more serious. If this issue frequently occurs, you may want to consider installing an energy-recovery ventilator, which will inject fresh air into the system every time the system cycles.

Frequent Cycles

An air conditioner should turn on and off as your home is cooled, the temperature slowly increases, and cools again. However, when this cycle occurs too frequently, or the AC is only on for 30-second intervals, it could be a sign that there is a clogged filter, the system is low on refrigerant, or the air conditioner is too big for the space. Replacing the filter can be done yourself, but if that doesn’t fix it, a professional air conditioning repair technician should take a look to determine the source of the problem.


There’s no doubt that Florida is a humid state, but your home shouldn’t feel humid when the AC unit is working properly. An air conditioning system should automatically regulate humidity levels, so if your home feels especially muggy, the unit could be the wrong size, the thermostat is set to the wrong setting, or you may simply have an older unit that can’t keep up with the workload. An AC unit can last between 15 and 20 years, so if yours is getting up there in age, contact a technician for a professional opinion on what to do next.

Water Leaks

Air conditioners produce condensation when it converts warm air to cool, but the water should never leak into your home. If you notice pools of water around the unit, there may be a leak in the system, which can lead to the unit not working properly, not to mention serious structural issues in your home. Schedule an appointment for AC repair as soon as you can.

Bad Smells

No one wants to put up with a foul smell in their home, and your air conditioning unit can produce a few odors.

  • Moldy or Mildew: If there is excess moisture in the system, it can lead to mold or mildew growth that can eventually emit an odor.
  • Cigarette Smoke: If anyone in the house has smoked, the smell could accumulate in the filter and evaporator coils.
  • Stinky Feet: When the evaporator coils are dirty, condensate drain pans are clogged, or there is stagnant water.
  • Burning: A motor may be overheating or wiring could be burned. Mechanical and electrical issues should be taken care of as quickly as possible.
  • Sulfur: This could be a sign of a gas leak.
  • Dirty Trash: Small critters can get caught in your duct system, producing a dirty trash smell.

Unusual Noise

You’re probably familiar with the normal start-up noises from your air conditioner, but when you start hearing a rattling, buzzing, whistling, or grinding sound, there’s something wrong. The seriousness of the problem will depend on the noise, so give an air conditioning repair company a call to thoroughly inspect the system.
