Here Are 10 Reasons Why Your AC is Not Blowing Cold?

As the summer heat rises in Florida, there’s nothing worse than your air conditioner not working properly. You turn it on, expecting cool air to rush out, but all you get is warm or even hot air. So, what’s going on? What’s causing this annoying issue? What can you do to fix it? In today’s blog, we’ll look at 10 of the most common reasons your AC isn’t blowing cold and offer some DIY solutions to help you when your AC is not blowing cold.

10 Reasons Why Your AC is Not Blowing Cold 

There are lots of different reasons why your AC might not be running as well as it should. It could be something as simple as setting the thermostat wrong or having a dirty filter, or it could be something more complicated like needing to replace some parts. We’ll go over some of the things you should look out for before you call for HVAC repair or AC installation people.

1. Wrong Thermostat Settings

Most of the time, the main cause of the problem is not the AC itself, but can be a malfunctioning thermostat instead. It is extremely important that you make sure that the temperature setting is set to cool and not heat as this can make the AC blowing warm air rather than cold air. 

2. Dirty or Clogged Air Filter

A clogged air filter can obstruct airflow and reduce your AC’s cooling effectiveness. Dust, debris, and pollutants accumulate over time, obstructing airflow. Depending on usage, it is suggested that you change or clean your air filter every 1-3 months. A clean filter ensures proper airflow, allowing your air conditioner to perform optimally.

3. Refrigerant Issues

The refrigerant component of an air conditioner is essential for the efficient cooling of the air. A defective refrigerant can cause your AC not blowing cold air. It is responsible for the circulation of heat from the air inside the system and the release of heat from the outside. If there is a leak in the refrigerant, the air conditioner will not be able to effectively cool the air. This puts added pressure on the compressor, specially in the hot and humid weather of Florida, that may lead to compressor failure and massive repair bill. Therefore, it’s always best to call local electrical experts who know the weather to diagnose and fix this ASAP. For example, if you’re in Jupiter FL, contact Jupiter AC repair experts or if you are in Stuart FL, contact Air Conditioning Repair Stuart FL.

Symptoms of a refrigerant issue may include a hissing sound, an accumulation of ice on the line, and a continuous warm airflow. Professional HVAC technicians can identify the source of the leak, fix it, and replenish the refrigerant with the appropriate amount. 

4. Compressor Problems

The compressor is an important part of your air conditioner because it compresses the refrigerant to cool the air. If your air conditioner isn’t working properly, it may blow warm air. Electrical problems, motor failures, or damage can all cause compressor problems. Unfortunately, compressor problems usually necessitate the services of an HVAC professional.

5. Inadequate Maintenance

Regular  maintenance is essential to keep your AC running at its best. Neglecting maintenance can lead to various issues such as AC not blowing cold. Over time, components can wear out or deteriorate, affecting the performance of the machine. Scheduling annual maintenance by a professional can help eliminate these problems and prolong the life of your AC.

6. Blocked or Dirty Evaporator and Condenser Coils

The evaporator coils and the condenser coils work together to exchange heat and cool the air. If these coils are dirty or clogged with dust and other debris, they are unable to transfer heat effectively. This leads to a decrease in cooling capacity and eventually the AC will blow warm air. Cleaning these coils regularly can help prevent this problem.

7. Faulty Fans or Motor

Your Air Conditioning System (AC) is equipped with fans that assist in the circulation of air and the expulsion of heat. A malfunctioning fan or appliance can disrupt the airflow in your home and cause warm air to blow through your home. It is recommended to Inspect the fans and their motors for damage or any unusually visible noise. If any issues are detected, contact HVAC repair professionals.

8. Electrical Problems

If your AC isn’t running as well as it should, most likely the AC is not blowing cold, it could be because of electrical problems. Things like bad wiring, tripping breakers, and a faulty capacitor can all mess with the AC’s ability to cool down the air. If you don’t want to deal with electrical problems yourself, it’s a good idea to get help from a local  electrician or a HVAC technician. That way, you won’t have to worry about any safety risks and get someone who understands the local weather-related issues, permits, grounding wires, etc..

9. Ductwork Problems

If your air conditioner is running smoothly but you’re still getting hot air, it could be a sign that your ductwork isn’t working properly. If your ducts are leaking, have gaps, or aren’t insulated, it could mean that cool air isn’t getting to where it needs to go in your home. Get a professional to take a look and seal up your ducts to make sure your cooling system is running as it should.

10. AC Size Mismatch

If you recently installed a new AC unit or moved into a new home with an existing unit, the size of the AC may not be suitable for the space it’s required to cool. A compact unit will struggle to cool the area, whereas a bigger one may cycle on and off too frequently, not allowing enough time to properly dehumidify and cool the air. Consult with an HVAC professional for AC installation to ensure you have the right dimension of AC for your space.
