The air sizzles, making your vision ripple with waves of heat. It’s not some parched desert – It’s just your house when the AC isn’t cold.
Luckily, you don’t have to sit around broiling in the high temperatures: There are a few things you can do to help fix the problem.
Assess the Problem
- Can I feel air blowing in the middle of the room as usual? How about next to the vent?
- Do I hear the AC running / feel it chugging away? Does it sound louder or weaker than normal?
- What is the thermostat doing? Are there any warnings on the screen? If I use a thermometer – or thermometer app – does it seem close to what the thermostat says?
- Are there puddles around the AC unit or do I see unnatural condensation?
Many issues can cause AC problems. By exploring the issue in detail, you’ll increase your odds of getting the right help and taking the proper corrective action.
After thoroughly describing the problem, you might find yourself in one of the following situations:
The AC Doesn’t Come On
Is your AC receiving power? Be sure it’s plugged into an outlet and that the outlet has power. Check whether you’ve tripped a breaker or blown a fuse.
Another culprit may be that your thermostat is set too high. Dial it down to a lower temperature to see if the AC will come on.
Finally, check to make sure no obstructions are blocking the airflow to the unit. Have you changed the filter lately?
Air Comes Out But Isn’t Cold
If your AC unit is blowing warm air, make sure that the thermostat is set to “cool” and that the temperature is lower than the current room temperature.
If the thermostat is set correctly and the AC still isn’t cooling, check to see if the outdoor unit is running. If it isn’t, there may be an issue with the power supply.
If the unit seems to struggle, you might have a problem with the evaporator coil – the bit that transfers heat from your home to the outdoor air. If this coil is dirty, it won’t be able to absorb heat properly and your home won’t get cool, which is why you ought to clean it annually.
No Air Comes Out Even Though the Unit Is Running
Does it seem like the outdoor unit is running, but the indoor unit isn’t blowing any air? There could be a problem with the blower motor or belt.
Do you hear your unit humming? This sound is likely an indication that the blower motor is trying to run but can’t. This could be the result of a faulty capacitor or a broken belt.

If you’ve checked all of these things and your AC still isn’t working properly, it’s time to call a professional AC company in Port ST Lucie. An experienced technician will be able to diagnose and fix the problem quickly so you can enjoy the cool again.
