If there was ever a region where a well-functioning air conditioning unit is vital to survival and comfort, it’s Jacksonville, Florida. While many people flock to the city because of its bountiful sunshine, having access to the cool relaxation of an A/C unit makes the worst of the heat more bearable. If your air conditioning unit is on and running — but not cooling your home or business — it could be due to one of these reasons. Common HVAC issues in St. Augustine include clogged air filters, clogged condensate lines, refrigerant leaks, frozen evaporator coils, electrical component failures, coastal corrosion, thermostat malfunctions, and poor indoor air quality. Clogged condensate lines can be prevented by pouring vinegar down the line or cleared by a professional.
Why is my HVAC unit running but not cooling properly?
If your HVAC system is running but not cooling your home, it’s typically because of these key issues:
- The thermostat may be set incorrectly (e.g., on “fan” instead of “cool”).
- Air filters or coils may be dirty or clogged, restricting airflow.
- The outdoor condenser unit may be blocked by debris or may have dirty coils preventing heat being expelled.
- Refrigerant levels may be too low (often from a leak), meaning the system can’t complete the cooling cycle.
- Major components like the compressor may be failing or electrical issues may be present, requiring professional repair.

Understanding Air Conditioning Systems
Air conditioning systems are intricate networks designed to keep your home cool and comfortable, even during the hottest Florida days. At the heart of every system are key components: the outdoor unit, which houses the compressor, condenser coil, and fan, and the indoor unit, which contains the evaporator coil and blower fan. These units work together to remove heat from your indoor air and circulate cool, refreshing air throughout your space.
Properly installed and maintained air ducts are essential for distributing cool air efficiently and maintaining high air quality. If ducts are poorly sealed or insulated, you could lose valuable cool air, leading to higher energy bills and uneven temperatures. That’s why our expert installation services focus on every detail, ensuring your system and air ducts are set up for optimal performance.
At AC Designs Inc., our technicians are skilled in working with all types of systems, including advanced heat pumps and high-efficiency furnaces.

1. Faulty or Broken Condenser
The purpose of your A/C unit’s condenser is to house the fan motor. If it’s faulty or broken, then the heat from your home or businesses can’t be properly dissipated. This, in turn, means that the structure never becomes cool. If the compressor inside the condenser is damaged, compressor replacement may be necessary to restore proper cooling.
2. Low Refrigerant Charge or Refrigerant Leak
Your A/C unit’s refrigerant is a vital aspect of its cooling function. It absorbs the excess heat inside before releasing it outdoors. If the refrigerant is low, it means that you may have a leak. Other signs include a bubbling or hissing noise and a build-up of ice on the outside unit and the refrigerant line. After addressing any leaks, a refrigerant recharge may be required to restore the system’s cooling capacity.
3. Dirty Air Filter
Regardless of what the manufacturer states on the air filters you purchase, you should replace them once per month. Regular filter replacement is essential to maintain optimal airflow and system efficiency. A dirty air filter makes it difficult for the A/C unit to circulate enough of the cooled air inside your home or business, which makes it hard to lower the inside temperature. Clogged air filters in HVAC systems should be replaced every 1-2 months during heavy use.
A dirty air filter can also restrict the flow of air so much that the evaporator coil freezes completely.
4. Dirty Outside Unit
The concept behind the functioning of an A/C unit is actually pretty simple. The evaporator, or inside the unit, absorbs the heat from indoors. This hot air is then transferred to the condenser which is the unit outside. The condenser can’t effectively do its job if it’s blocked with leaves, twigs and other debris, or if it’s dirty. A quick monthly inspection can help prevent your outside unit from getting too dirty or blocked completely. Regular coil cleaning is also important to ensure efficient heat transfer and prevent cooling issues.
Any cooling issues you’re experiencing with your commercial or residential A/C unit need the attention of a professional and experienced team that offers specialized services. A/C Designs has been proudly servicing Jacksonville with air conditioning solutions including maintenance, repair, installation and more. If you are concerned your HVAC system isn’t cooling like it should contact us today to schedule a comprehensive inspection.
Understanding Humidity Control
Living in St. Augustine, FL, means dealing with high humidity levels for much of the year, making humidity control a vital part of your home’s comfort and air quality. Proper humidity management not only helps maintain a comfortable temperature but also protects your home from the damaging effects of excess moisture, such as mold growth and warped furniture. On the flip side, air that’s too dry can lead to discomfort like dry skin and respiratory irritation. That’s why a well-maintained HVAC system is essential for balancing humidity and ensuring your indoor environment stays healthy and pleasant.
Modern air conditioning systems, heat pumps, and furnaces are designed to do more than just cool or heat your home—they also help regulate humidity. By integrating solutions like dehumidifiers and humidistats, you can keep moisture levels in check and prevent potential problems before they start. Professional dehumidifier installation is an effective way to manage excess humidity in your home, ensuring optimal performance and long-term protection. Proper ventilation, including clean and well-maintained air ducts, is another key factor in controlling humidity and improving overall air quality.
Routine maintenance is crucial for keeping your HVAC system working properly and ensuring it can effectively manage humidity. Scheduling regular tune-ups, cleaning your air ducts, and replacing filters all contribute to a system that runs efficiently, delivers top notch service, and helps lower your energy bills. Our experienced technicians are fully licensed and committed to providing quality service at fair prices, whether you need a new install, replacement services, or a simple repair.

Benefits of Regular Maintenance
Keeping your HVAC system in top shape is essential for maintaining comfort and air quality in your St. Augustine, FL home. Regular maintenance is the key to ensuring your air conditioning, heat pumps, and furnaces are working properly year-round. Coastal corrosion of HVAC systems can be slowed with regular cleaning and professional maintenance. Poor indoor air quality can be improved with filter changes, dehumidifiers, duct cleaning, and air purifiers. By scheduling routine service with experienced technicians, you can avoid frequent breakdowns, strange noises, and even mold growth that can compromise your indoor air quality and lead to costly repairs. Preventive maintenance helps identify and address potential issues early, reducing the risk of unexpected and expensive repairs.
A well-maintained HVAC system not only keeps your home cool during the hottest months but also helps reduce energy bills by running more efficiently. Regular cleaning and inspections of your air ducts and system components can prevent dust and debris from building up, ensuring that your air conditioning delivers clean, cool air throughout your house.
Frequently Asked Questions
Question: What are the most common reasons my air conditioning unit isn’t cooling my home?
Answer: Common reasons include a malfunctioning condenser unit, low or leaking refrigerant, a dirty air filter restricting airflow, or the outdoor unit being blocked by debris. Each of these issues can prevent the system from effectively cooling your space.
Question: How can a dirty air filter prevent my AC from cooling properly?
Answer: A clogged air filter limits airflow through the system, reducing efficiency. This can cause the evaporator coil to freeze, block cold air from circulating, and make the system work harder, all of which reduce its cooling ability.
Question: Why would low refrigerant or a refrigerant leak make my AC warm instead of cool?
Answer: Refrigerant absorbs heat from inside your home. If the level is low due to a leak or undercharge, the system can’t transfer heat properly, leading to warm air, poor cooling, and possibly ice buildup on the refrigerant lines.
Question: What role does the outdoor condenser unit play, and how can it stop the cooling process?
Answer: The outdoor condenser releases the heat pulled from your home. If it’s blocked by dirt, leaves, or debris, or if the fan fails, heat can’t escape. This stops the cooling cycle, even though the system appears to be running.
Question: When should I call a professional technician rather than try DIY fixes?
Answer: If changing the filter and clearing debris doesn’t help, it’s time to call a technician. Issues like refrigerant leaks, frozen coils, compressor problems, or electrical faults require professional tools and expertise to diagnose and fix.
