If you live in Port St. Lucie, you probably know that your air conditioner (AC) is prone to gradual wear and tear. Even air conditioning systems that have been expertly installed and maintained are exposed to wear and tear during everyday use.

AC repairs can be extremely costly, which is why you should schedule routine inspection and maintenance with skilled AC technicians to ensure your unit functions optimally. In addition, it’s essential to understand the most common air conditioning problems in Port St. Lucie so that you can implement the best preventative measures.

Here are the common AC problems experienced by homeowners in Port St. Lucie

AC refrigerant leak repair

AC Refrigerant Leak

AC refrigerant leaks are a common problem that’s not easy to detect because they occur along coolant lines. Stains near the air conditioning system indicate problems. When the refrigerant in your AC begins leaking, you may experience varying temperatures, and the system will not perform at its best. We can perform a leak check on the system and find the issue pretty quickly.

Air Conditioner Running Constantly

Your air conditioner is supposed to turn off periodically during operation, even on hot days. But if it won’t shut off, it means there is a serious problem. Multiple things can make the AC run constantly. These include issues with the thermostat, electrical parts, clogged air filters, or compressor.

To troubleshoot this problem, check the AC‘s thermostat batteries and replace them if they are worn out. If the batteries are in good shape, confirm the thermostat setting to ensure the cooling mode is correctly adjusted. You may also want to check and reset the circuit breaker if it’s tripped. If nothing works, contact a professional to help identify and fix the problem.

No Cool Air Flowing

This is one of the most common AC problems. It occurs when your AC fails or stops to send air to the outside while in operation. This problem can also appear when the air sent out doesn’t provide any cooling effect. Things that can affect airflow include a tripped circuit breaker, a worn-out blower belt, and low refrigerant levels.

Having a qualified HVAC professional on your side to perform routine system tune-up can alleviate this problem. An experienced technician will fix existing issues, check for wear and tear, and prevent potential breakdowns.

AC System Freezing

Ice buildup around your air conditioning system means the unit is struggling to keep your home cool. Your AC system can freeze due to low coolant levels, stuck contractors, insufficient airflow, blow motor problems, and low outside temperature. The best way to address this problem is to get a technician to check ducts, blower fan, and condenser for any interference.

AC Making Noises


You should pay attention to your AC if it starts making strange noises. These noises could indicate a series of problems, which can result from a refrigerant leak which can generate a hissing. A clicking sound could mean a relay issue, and screeching noise indicates a compressor problem. A buzzing sound means there are some faulty electrical components. On the hand, rattling or thumbing noises are a sign of motor or blower issues.

Inadequate Maintenance

Even if your AC unit is expertly designed and installed, it needs regular servicing to perform its functions optimally. Failing to do so can make air filters and AC coils dirty, affecting their performance or even leading to premature failure.

Drainage Problem

A clogged drain pipeline can also affect your system’s performance. Dirt, dust, and algae are common causes of drainage systems. Poor water drainage can cause a series of problems and encourage the growth of fungus, mold, and mildew. This can also cause foul odors and gasses to enter your home. The best way to eliminate this issue is to ensure that your drain line is frequently inspected, cleaned, and serviced.
