Are you asking yourself **why does my AC blow hot air**? In this guide, you'll learn the top reasons your air conditioner might be and:

- [Discover solutions to keep your home cool and comfy](#solutions-to-common-problems)
- [Learn when it's time to call in the experts](#when-to-call-a-professional)

And so much more! Let's dive in.

## Common Reasons Why Your AC Is Blowing Hot Air:

### 1. Thermostat Settings

Incorrect settings can cause the air conditioning unit to blow warm air. The thermostat acts as the control center for your air conditioning system. I remember last summer, I was confused when my house started feeling warm. After hours of frustration, I realized I had accidentally set the thermostat to heat instead of cool. A simple switch made all the difference! It is crucial to check your thermostat and ensure it is on "cool" and the temperature is lower than the current room temperature. Additionally, make sure your thermostat is not out of battery and replace them if necessary.

### 2. Clogged Air Filter 

![Dirty Filters](https://res.cloudinary.com/dbcmnng4b/image/upload/v1697630489/dirty_filters_2ff7e1df9b.jpg)

A dirty air filter can restrict airflow and reduce the unit's efficiency. The filter in your AC system plays a vital role in maintaining indoor air quality and performance. We have had clients contact us about their allergies and inability to find the cause. After our team inspected their AC, we discovered the filter was full of dust and pet hair. Replacing it not only improved the air quality but also the temperatures in the house. Over time, the filter can become clogged with dust, debris, and other particles, obstructing airflow. When airflow is restricted, the air conditioner has to work harder to cool, resulting in warm air blowing into the room. Cleaning or replacing the air filter is essential to prevent this issue.

### 3. Refrigerant Issues 

Low refrigerant can impact cooling efficiency. Refrigerant handles absorbing heat from indoor air and transferring it outside. The AC will struggle to cool the air if the refrigerant level is low. As a result, your air conditioner might be blowing warm air or fail to cool the room. Have an HVAC expert check and fix refrigerant leaks for the best cooling.

### 4. Electrical Issues

Faulty capacitors or breakers can hinder proper cooling. Electrical components, such as capacitors and breakers, are crucial in operating your unit. If these components malfunction or fail, it can disrupt the cooling process and cause your AC to not blow cool air. A broken capacitor can stop the AC compressor from starting, and flipped breakers can keep the unit from turning on. It is best to have an HVAC technician diagnose and repair any electrical issues to restore proper cooling functionality.

### 5. Evaporator Coil Issues 

A dirty or [frozen coil](https://www.hvac.com/expert-advice/no-cool-air-a-frozen-coil-may-be-the-cause/) can impede cooling. The evaporator coil absorbs heat from the air, allowing the AC to cool down. But, over time, the coil can accumulate dirt, dust, and other pollutants, reducing its ability to absorb heat. Also, suppose the coil becomes frozen due to restricted airflow or refrigerant issues. In that case, it won't be able to cool the air. Keep the evaporator coil clean and maintained for efficient cooling.

### 6. Condenser Issues 

Blocked or dirty condensers can decrease cooling efficiency. The condenser unit, located outside, plays a vital role in releasing heat absorbed from indoor air. If dirt, debris, or plants block the condenser fins, they can stop heat from escaping, making the cooling less effective. It's essential to clean and maintain the condenser to avoid blockages and keep the cooling at its best.

### 7. Ductwork Problems 

Blockages or holes in the ducts can lead to warm air flowing through the house. The ductwork in your home carries cooled air from the AC to each room. If your [ducts have leaks](https://cielowigle.com/blog/how-to-find-air-duct-leaks/) or blockages, the air can escape or be restricted, resulting in warm air throughout the house. Inspecting the ductwork and repairing any leaks or blockages is essential to ensure proper airflow and cooling.

You can keep your home cool by addressing these issues and implementing the suggested solutions. Remember that maintaining your AC and calling in experts when necessary will help you stay cool and comfortable all year round!

## Solutions to Common Problems:

Knowing when to call an HVAC expert is crucial for maintaining the optimal performance of your air conditioning system. Some AC problems are simple, but some signs indicate you should call a professional.

### 1. Unusual Noises 

If you hear strange or [loud noises from your AC](https://www.angi.com/articles/5-hvac-system-sounds-you-dont-want-hear.htm) unit, it indicates something is wrong. Rattling, grinding, or banging sounds suggest a loose or damaged component, such as a motor or fan blade. It's important to avoid attempting DIY fixes for these issues, as it can be risky and may cause further damage or injury. The best action is to call an HVAC professional to diagnose the problem and provide the necessary AC repairs.

If your AC turns on and off, it could indicate an underlying issue. This behavior, known as short cycling, can be caused by various factors, including a bad thermostat, dirty filters, or an under-sized AC unit. It can use more energy and wear out your system faster. Getting HVAC experts to fix your air conditioner is best.

### 3. Weak Airflow

If your AC vents have weak airflow, it might be due to a faulty blower motor or blocked ducts. You can quickly check and clean the air filters. But, it's best to call a professional for blower motor or duct issues. An HVAC technician will be able to identify the root cause of the weak airflow and take the necessary steps to restore proper ventilation.

### 4. Foul Odors

If your AC system emits unpleasant odors, such as a [musty or burning smell](https://www.trane.com/residential/en/resources/blog/does-your-air-conditioner-smell-heres-what-it-means/), it's essential to address the issue. Mold or mildew growth, a malfunctioning electrical component, or a problem with the refrigerant can cause these odors. Finding and fixing the smell alone can be challenging and might not solve the issue. An HVAC expert can inspect your system, identify the cause of the odor, and provide the appropriate solution.

### 5. Frequent Repairs

If your AC keeps breaking down or has the same problem often, there's likely a more significant issue. While it may be tempting to continue attempting DIY repairs, it can cost you more in the long run. An HVAC expert can find and fix the problem and give you a lasting solution, ensuring your AC works for years.

Remember: Fixing your AC without the right skills can be risky and might cancel your warranty. Call an HVAC expert to handle any [air conditioner repairs](/services/ac-repair) for safety and the best results. They'll make sure your system works well for a long time.

In conclusion, regular [air conditioner maintenance](https://www.energy.gov/energysaver/maintaining-your-air-conditioner) and timely repairs are crucial for optimal performance and longevity of your A/C system.

Save Money with an Energy-Efficient AC

Many homeowners and business owners looking to create healthier environments turn to air purifiers. Whether it’s for odor control or the removal of germs, there are decisions to be made about where air purifiers are most effective.

The air conditioner at your home or business has the critical job of keeping the place cool and comfortable throughout the year but the indoor air quality at your home or business is just as important.

Some property owners choose to include an air purifier within their air conditioning unit, allowing airflow, temperature, and quality to work in tandem. So do they work, and are they worth it? The following are just a few things to consider when asking yourself these questions.

![Air Purifier|priority](https://res.cloudinary.com/dbcmnng4b/image/upload/v1676829016/Air_Purifier_7f0a2cb3d5.jpg)

#### Understanding What an Air Purifier Does in Your Air Conditioner

You may be familiar with the process of swapping out traditional box filters every couple of months. The inclusion of an air purifier for an air conditioner takes the cleansing process a step further.

Incorporating it into the air conditioning system is generally an attempt to capture particles, viruses, pollutants, and allergens more effectively before they ever enter your air ducts and spread through the property. In-duct or those that go inside your air handler unit are some of the options to consider.

#### Evaluate the Benefits

Air pollutants can cause severe respiratory issues, particularly for those with known allergies or asthma. Including an air purifier for your air conditioning unit is an added preventative step towards achieving a cleaner, healthier air to breathe in a living and working space. Some individuals find that this added barrier against germs keeps viruses at bay throughout the year. A third-party study revealed that RGF’s REME HALO® air purifier technology has an efficacy of 99.9% against COVID-19.

 #### Cost Considerations 

The cost of an air purifier for an air conditioner paired with the price of installation can be quite an investment for property owners. The decision to have one installed is often something to save and plan for in advance.

While having it installed into an existing air conditioning unit can be costly, timing can affect that final price tag. In general, it’s less expensive to have it included with the purchase of your new air conditioning unit.
