At Ashley Brothers Heating & Cooling, we know just how important a functioning air conditioning system is—especially during those sweltering summer months. Whether you’re at home or running a business, when the AC starts acting up, it quickly turns into an uncomfortable (and sometimes even dangerous) situation. Fortunately, most common AC problems can be fixed quickly and efficiently—if you know what to look for and have the right team on your side. In this post, we’re pulling back the curtain on the most frequent issues our technicians see in the field, and how we resolve them fast so you can stay cool and comfortable.
When Your AC Won’t Turn On
One of the most common issues our customers call us about is a unit that simply won’t turn on. If you’re wondering “why is my ac not working?”—this is often the first sign. Several factors could be at play here, and our experienced technicians always begin by checking the basics: thermostat settings, power sources, and circuit breakers. Believe it or not, a tripped breaker or dead thermostat battery is often the culprit.
If the power supply isn’t the issue, we then look into deeper mechanical problems such as a failed capacitor, blown fuse, or malfunctioning contactor. These are critical components that regulate how and when your air conditioner powers on. Our team carries a full inventory of replacement parts to ensure we can swap out faulty pieces on the spot, eliminating long wait times and keeping your home cool.
Because we know every hour without AC is a big deal, Ashley Brothers Heating & Cooling is structured for rapid response. Our trucks are stocked, our techs are trained, and our dispatch system is designed to get us to your doorstep as quickly as possible.
AC Blowing Warm Air
Another frequent concern we hear is that the air conditioning unit is running—but it’s blowing warm air instead of cool. This frustrating problem can have a few different causes. One of the most common is restricted airflow, typically due to a dirty air filter or a blocked return vent. During a service call, our team checks the entire air pathway, replacing filters and clearing blockages to restore full function.
Another potential issue is a refrigerant leak. Refrigerant is the lifeblood of your cooling system, and if levels drop too low, your AC simply can’t cool the air. Signs of a leak include hissing noises, frozen coils, or reduced airflow. If we suspect a refrigerant issue, we’ll run diagnostic tests to locate the leak, seal it properly, and recharge the system to manufacturer specifications.
Compressor problems and faulty thermostats are also suspects in this scenario. Our comprehensive diagnostic tools allow us to determine exactly what’s wrong without guesswork, giving you an accurate quote and a clear repair plan on the spot.
Strange Noises from the Unit
Air conditioners should be heard, not noticed. A slight hum or the sound of rushing air is normal—but if your unit starts to grind, squeal, rattle, or buzz, it’s time to call the pros. Odd noises are often the first sign of a part that’s wearing out or already broken.
Grinding noises often indicate a problem with the motor bearings. Squealing could mean a belt is loose or worn. Rattling might point to loose hardware or debris inside the unit. Buzzing can stem from electrical issues, including a failing capacitor or a contactor that won’t engage properly. These types of problems rarely go away on their own and usually get worse with time, so fast intervention is key.
At Ashley Brothers Heating & Cooling, we prioritize these service calls because we know the sound is more than just annoying—it’s a signal of deeper trouble. We’ll isolate the sound, identify the faulty part, and either repair or replace it on the spot. In most cases, we can restore your AC to full function during the same visit, thanks to our commitment to fully stocked vehicles and trained staff.
Water Leaks and Drainage Issues
It’s not unusual for homeowners to call us in a panic after noticing water pooling around their AC unit. Although it may seem alarming, this is actually a common and usually fixable problem. Most AC systems create condensation as part of the cooling process, and that water is typically channeled away through a drain line. If that line becomes clogged, broken, or disconnected, you’ll end up with water where it shouldn’t be.
When we respond to these calls, our first step is inspecting the drain line and clearing any obstructions—often caused by dirt, mold, or algae buildup. In more severe cases, we may need to replace the line or address issues with the drain pan. If left unchecked, drainage issues can lead to mold growth, water damage, and even electrical hazards, so we take every leak seriously.
We also check the evaporator coil for freezing, which can cause overflow when it thaws. If we find frozen coils, that typically indicates restricted airflow or low refrigerant—both of which we’ll resolve as part of the same service. That’s one of the key reasons why our customers trust our ac repairs: we get to the root of the problem instead of applying temporary fixes.
Uneven Cooling Throughout the Home
Have you ever walked from one room into another and felt a dramatic difference in temperature? Uneven cooling is one of the more subtle but persistent AC problems we fix. This often happens due to issues in the ductwork—such as leaks, blockages, or poorly designed layouts that fail to deliver balanced airflow.
Our team uses airflow meters and infrared technology to diagnose these inconsistencies. If we find leaks in your ductwork, we’ll seal them with professional-grade materials. If poor design is the issue, we’ll recommend and implement adjustments to balance your system better. In some cases, the issue is with zoning, or the need for better thermostatic control in larger homes. We can install smart thermostats and zoning systems to give you precise control over each area of your home.
Sometimes, the root cause is as simple as a neglected air filter or an AC unit that’s not appropriately sized for your space. During every call, we conduct a full system evaluation to ensure your cooling setup is optimized for efficiency and comfort. Our air conditioning tips are always customized to your home’s layout and your lifestyle needs.
Preventative Maintenance: Our Best Fix is the One You Don’t Need
While we pride ourselves on being fast and efficient at solving problems, we’re even bigger believers in stopping them before they start. One of the best things you can do for your AC system is to invest in routine maintenance. Our preventative maintenance services are designed to catch small problems before they become big repairs—and keep your system running smoothly all season long.
During a typical maintenance visit, we’ll inspect every component of your system: from refrigerant levels and electrical connections to fan motors and filters. We’ll clean the coils, test for efficiency, and make minor adjustments that can extend the life of your unit. You’ll get a full report on the condition of your system and practical advice on how to fix ac problems before they interrupt your comfort.
Many of our clients sign up for our seasonal maintenance plans, which include priority scheduling, discounted repairs, and peace of mind that your AC is ready to handle even the hottest days. If you’ve ever asked yourself “why is my ac not working” in the middle of July, you know the value of being proactive.
Conclusion
At Ashley Brothers Heating & Cooling, we believe in service that’s fast, friendly, and always focused on long-term value. Whether it’s your first time calling us or you’ve been with us for years, we treat every home like it’s our own—and every system like it’s mission critical. When you need ac repairs, we’re just a call away.
We’re here to keep your home comfortable, your AC running at its best, and your summer stress-free. Stay cool—and remember, the sooner you call, the faster we fix it.

Living in St. Louis means dealing with a wide range of weather extremes. From sweltering, humid summers to bone-chilling winters, the HVAC system in your home isn’t just a luxury—it’s a lifeline. When your air conditioner fails during a heatwave or your furnace breaks down during a cold snap, waiting hours or even days for help can be both uncomfortable and dangerous. That’s why emergency HVAC repair is not just a convenience but a necessity for St. Louis homeowners. Having access to 24 hour HVAC repair in St. Louis can mean the difference between a minor inconvenience and a full-blown crisis.
The Unpredictable Nature of HVAC Failures
HVAC systems are machines, and like all machines, they can break down—often at the most inconvenient times. Unfortunately, breakdowns don’t stick to business hours. You might discover your furnace isn’t working at 3 a.m. on a snowy January night, or your air conditioner may quit during a Fourth of July heatwave. These situations can be more than uncomfortable—they can be hazardous, particularly for families with infants, elderly residents, or individuals with health conditions that require a regulated indoor climate.
In St. Louis, where the weather can change dramatically within a 24-hour period, these scenarios are not uncommon. The high humidity in the summer exacerbates the heat, making indoor conditions stifling without air conditioning. Likewise, a sudden cold front in winter can quickly lead to freezing indoor temperatures. That’s why homeowners can’t afford to wait until regular business hours to resolve HVAC issues. An AC repair emergency needs to be handled as soon as it occurs, and that requires services that are available at all times of the day and night.
Safety and Health Concerns
One of the most critical reasons emergency HVAC repair services are so important is safety. Extreme temperatures can have serious health implications. In the summer, excessive heat can lead to heat exhaustion or heatstroke. In severe cases, it can even be life-threatening, especially for the elderly or very young. In winter, the risks include hypothermia and complications from pre-existing conditions aggravated by cold air. Even pets can suffer from temperature extremes if the HVAC system fails unexpectedly.
24 hour HVAC repair in St. Louis ensures that you and your loved ones are protected no matter when an HVAC failure occurs. It’s not just about comfort; it’s about maintaining a safe and livable home environment. Waiting for hours or days for service during an HVAC crisis can increase the likelihood of medical emergencies. Having a reliable service provider on call around the clock is one of the most proactive steps a homeowner can take to safeguard their family’s health.
Additionally, when HVAC systems are down, there’s an increased risk of secondary damage to the home. Pipes can freeze and burst in the winter without adequate heating, and high humidity without air conditioning can lead to mold and mildew issues. Both scenarios can cause costly damage and require extensive remediation. Emergency HVAC services can prevent these issues before they escalate, saving homeowners money and stress.
The Peace of Mind That Comes with 24/7 Availability
There’s something incredibly reassuring about knowing that help is just a phone call away, regardless of the hour. For homeowners, that peace of mind is invaluable. Whether it’s a holiday, a weekend, or the middle of the night, knowing that your emergency HVAC repair needs can be addressed immediately brings a sense of control during stressful times.
In St. Louis, where HVAC demand peaks during the extreme weather months, standard repair services may become overwhelmed, leading to long wait times. But 24/7 services prioritize emergencies, ensuring that urgent issues are resolved swiftly. This immediate response reduces the duration of discomfort and minimizes potential damage to your home.
Moreover, companies that offer 24 hour HVAC repair in St. Louis often have highly skilled technicians on call who are trained to handle a wide range of emergencies. These professionals arrive prepared with the tools and parts needed to make on-the-spot repairs, further speeding up the process and ensuring quality service. Quick resolution means your home gets back to normal faster, allowing you to rest easier.
Cost Versus Value: Why It’s Worth It
Some homeowners hesitate to use 24/7 emergency HVAC services due to perceived cost. It’s true that after-hours service might come at a premium. However, when weighed against the potential costs of delaying repairs—such as emergency room visits, home damage from burst pipes or mold, or even temporary relocation—the value becomes clear.
In St. Louis, where weather can be harsh and change rapidly, waiting until morning or the next available appointment simply isn’t practical. The benefits of 24/7 heating and cooling service extend beyond immediate repair. It’s also about maintaining the long-term integrity of your HVAC system and the comfort of your living space. Emergency services often include thorough diagnostics and preventative tips, helping you avoid future breakdowns and extending the life of your equipment.
Additionally, many companies offer service plans or memberships that include priority emergency service, waived after-hours fees, and discounts on parts and labor. These plans make 24/7 service more accessible and cost-effective in the long run. For St. Louis homeowners, investing in such plans can pay off significantly when the inevitable emergency occurs.
Choosing the Right Emergency HVAC Partner in St. Louis
Not all HVAC companies are created equal, especially when it comes to emergency services. St. Louis homeowners should seek out providers with a proven track record of reliability, speed, and expertise. Reviews, certifications, and service guarantees are all indicators of a reputable emergency HVAC repair company.
Look for companies that explicitly advertise 24 hour HVAC repair in St. Louis and ensure they have real humans answering the phone around the clock—not just voicemail or automated systems. Communication is critical in emergencies, and a company that responds quickly and clearly is one you can trust.
It’s also wise to establish a relationship with a local HVAC provider before an emergency happens. Schedule routine maintenance, get to know their technicians, and ask about their emergency protocols. That way, when you’re facing an AC repair emergency or a midnight furnace failure, you’re not scrambling to find a trustworthy provider—you already have one on speed dial.
Conclusion
The benefits of 24/7 heating and cooling service for St. Louis homeowners are numerous and significant. From ensuring safety during extreme weather, to providing peace of mind and protecting your home investment, emergency HVAC services are a crucial resource. Don’t wait until a crisis strikes. Be prepared and proactive by choosing a dependable emergency HVAC partner who can keep your home safe, comfortable, and functioning—no matter what time it is.

When the summer heat hits its peak and your home feels more like a sauna than a sanctuary, the last thing you want is an air conditioner that refuses to do its job. Few things are more frustrating than a malfunctioning AC, especially when it’s supposed to be your shield against the sweltering sun. But before you resign yourself to sweaty days and sleepless nights, take a closer look at the possible reasons why your AC isn’t cooling. Often, the problem can be pinpointed and resolved with a little know-how, saving you from unnecessary discomfort and costly repairs. In this blog post, we’ll explore common reasons your AC might be failing and offer actionable ac repair tips and solutions to get your home feeling cool and comfortable again.
Common Culprits Behind Inefficient Cooling
There are numerous factors that can hinder an air conditioner’s ability to cool a space effectively. One of the most frequent issues is a clogged air filter. Air filters trap dust, dirt, and allergens to maintain air quality, but when they become too dirty, they can restrict airflow. This reduced airflow forces your system to work harder, and over time, it hampers its cooling efficiency. If your AC seems sluggish, this is one of the first areas you should check.
Low refrigerant levels are another common problem. The refrigerant is the chemical responsible for absorbing heat from inside your home and releasing it outdoors. If there’s a leak or the levels are insufficient, your AC won’t be able to complete the cooling cycle efficiently. Unlike a clogged filter, dealing with refrigerant is not a DIY task. If you suspect this is the issue, professional ac repair is essential.
Another often overlooked culprit is a dirty condenser coil. Located in the outdoor unit, the condenser coil releases the heat absorbed from your home. When it’s coated with grime, it can’t perform this function effectively, which leads to poor cooling. Regular ac maintenance should include cleaning this component to ensure it’s operating at peak performance.
Finally, incorrect thermostat settings or a malfunctioning thermostat can lead to cooling issues. It might sound trivial, but sometimes the problem lies not with the unit but with the device telling it what to do. Always verify that your thermostat is set to “cool” and that the temperature is set lower than the room’s current reading. If your thermostat is battery-operated, replacing the batteries might also solve the problem.
The Importance of Routine AC Maintenance
Most air conditioner problems are preventable with regular ac maintenance. Just like a car needs oil changes and tire rotations to stay roadworthy, your AC needs attention to remain efficient. Maintenance routines should be performed at least twice a year—ideally in the spring and fall—to prepare for the heavy demands of summer and winter.
A typical maintenance check will include cleaning or replacing filters, inspecting and cleaning coils, checking refrigerant levels, testing the thermostat, and ensuring that all electrical connections are secure. While some of these tasks can be done by homeowners, such as changing filters or cleaning the accessible parts of the unit, a licensed technician should handle the more technical aspects.
Regular maintenance does more than just improve cooling efficiency. It extends the lifespan of your air conditioner, improves indoor air quality, and lowers your energy bills. An AC system that has to work harder due to neglect will consume more power, putting a strain on both your unit and your wallet. Moreover, staying on top of maintenance reduces the likelihood of sudden breakdowns during the hottest days of the year when HVAC professionals are hardest to book.
When to DIY and When to Call the Pros
It’s tempting to take a DIY approach to ac repair, especially with countless online tutorials promising quick fixes. While certain tasks are safe and manageable, others can be dangerous or cause more harm than good if not performed correctly. Understanding where to draw the line is essential.
Cleaning or replacing the air filter is a safe and necessary DIY task that homeowners should do regularly. Keeping the area around the outdoor unit clear of debris is another task that can help ensure proper airflow. Also, resetting a tripped circuit breaker or verifying thermostat settings are simple steps you can handle yourself.
However, if the issue involves refrigerant, electrical components, or internal parts of the unit, it’s best to leave it to professionals. Improper handling of refrigerant can pose serious health risks and even legal consequences due to environmental regulations. Electrical repairs, too, can be dangerous and should only be undertaken by certified technicians.
Calling in the experts also ensures that the problem is diagnosed accurately. What might seem like a simple issue on the surface could be a symptom of a more complex underlying problem. By relying on professional ac repair services, you can rest assured that your system is in capable hands, and you’ll avoid the risk of making the problem worse.
Understanding the Role of System Age and Sizing
Sometimes, the reason your AC isn’t cooling efficiently isn’t due to malfunction, but rather due to the age of the unit or incorrect sizing. Air conditioners typically have a lifespan of 10 to 15 years. As they age, their efficiency naturally declines. If your system is over a decade old and has required multiple repairs in recent years, it may be more cost-effective to replace it with a newer, more energy-efficient model.
Additionally, the size of your air conditioner relative to the space it needs to cool plays a crucial role. An undersized unit will struggle to keep your home at a comfortable temperature, running continuously without achieving the desired results. Conversely, an oversized unit will cool the space too quickly without adequately dehumidifying it, leading to a cold yet clammy atmosphere.
Proper sizing involves calculating the load based on your home’s square footage, insulation, windows, and other factors. This is not something that should be guessed or estimated—it requires a professional load calculation. If you suspect that your AC’s poor performance is due to improper sizing, it’s worth consulting with an HVAC expert who can evaluate your system and recommend the right solution.
Future-Proofing Your Cooling System
Once your current issues are resolved, the focus should shift toward preventing future problems. Implementing a long-term ac maintenance strategy will ensure your unit remains in peak condition year after year. Investing in a maintenance agreement with a trusted HVAC company can be a smart move, as these plans often include scheduled inspections, priority service, and discounts on repairs.
Additionally, smart thermostats can enhance your system’s efficiency by allowing you to program cooling schedules and monitor performance remotely. Some advanced models even alert you to maintenance needs or unusual activity within the system. These tools help you stay proactive rather than reactive, which is key to maintaining a comfortable and efficient home environment.
It’s also wise to keep an eye on your energy bills. A sudden spike could indicate that your AC is struggling and needs attention. The earlier you catch potential issues, the easier and cheaper they are to fix. Simple steps like sealing air leaks, insulating ducts, and using ceiling fans to circulate cool air can also support your air conditioner’s performance.
Lastly, don’t forget to consider environmental factors. Shading your outdoor unit with plants or a cover (without obstructing airflow) can help it operate more efficiently. Likewise, using blinds or curtains to block sunlight during the hottest parts of the day can reduce the cooling load inside your home.
Conclusion
Staying vigilant and informed is the best defense against an underperforming AC. Whether it’s making minor adjustments, performing routine maintenance, or calling in the pros for ac repair, each step you take contributes to a more comfortable and energy-efficient living space. The next time your air conditioner starts to falter, you’ll be equipped with the knowledge to act quickly and effectively, keeping your cool no matter how high the temperature climbs.

When the heat of summer rolls in, there’s nothing more comforting than a well-functioning air conditioning system. However, air conditioning units, like any other home appliance, are susceptible to problems over time. Whether it’s a system that suddenly stops cooling, a strange noise emanating from the vents, or a musty odor, these common AC problems can be a real headache. As a homeowner, it’s tempting to want to fix things yourself, especially when it seems like a simple problem. But when should you roll up your sleeves and tackle the issue, and when should you call a professional HVAC technician? In this blog, we’ll explore common AC issues and provide HVAC repair tips, so you can determine when it’s time to get your hands dirty and when you should call in the pros.
Understanding Your AC Unit and the Importance of Proper Maintenance
Before deciding whether to fix an air conditioner that won’t cool yourself, it’s essential to understand how your air conditioning unit works. Air conditioners are complex systems designed to cool the air in your home by circulating refrigerant and transferring heat from inside the house to the outside environment. Over time, parts of the system may experience wear and tear, or dirt and debris can accumulate, causing the system to operate inefficiently. Regular maintenance is crucial to keep the system running smoothly and avoid costly repairs. Some common maintenance tasks include changing the air filters, cleaning the condenser coils, and ensuring that the thermostat is calibrated properly.
Routine maintenance can prevent many issues, but it’s not always enough. Understanding the complexity of your system can help you determine when to address problems on your own and when to call in a professional. The next section covers some of the most common air conditioning issues and helps you decide if they’re DIY fixable or require expert intervention.
Common Air Conditioning Problems and DIY Fixes
There are a number of air conditioning issues that homeowners may be able to fix themselves. Some of these problems are relatively simple to diagnose and repair, while others may require more extensive expertise. Below are a few common AC problems and HVAC repair tips to help you assess whether you should try to fix them yourself or call a pro.
1. Clogged or Dirty Air Filter
One of the most common air conditioning problems is a clogged or dirty air filter. Air filters are designed to trap dust, dirt, and other particles from the air, preventing them from entering the AC unit. When the filter becomes clogged, it restricts airflow and can cause the air conditioner to work harder, resulting in poor cooling performance or even system failure.
Fortunately, this is an easy fix for homeowners. Replacing or cleaning the air filter is a simple task that can be done in just a few minutes. Most air filters need to be replaced every one to three months, depending on usage. If you haven’t checked your filter in a while, this is the first thing you should do when your AC isn’t cooling properly.
2. Thermostat Issues
Sometimes, an air conditioner might not be cooling your home because the thermostat is malfunctioning. This could be due to dead batteries, incorrect settings, or a broken thermostat. In many cases, the issue can be resolved by simply replacing the batteries or adjusting the settings on the thermostat. However, if your thermostat is not responding at all, it could be a sign of a deeper issue, such as a faulty wiring connection or a failed sensor.
Testing your thermostat is straightforward—set it to a lower temperature and check if the AC kicks on. If the system doesn’t respond or the temperature doesn’t change, you might need to replace the thermostat or get it recalibrated. Replacing a thermostat is typically a task you can do on your own, but if you suspect wiring or sensor issues, it’s better to call in a professional.
3. Frozen Evaporator Coils
Frozen evaporator coils are another common AC issue. When the coils freeze, the air conditioner will stop cooling properly, and ice may start to form on the coils. This problem is usually caused by poor airflow, low refrigerant levels, or a dirty air filter. If you suspect your evaporator coils are frozen, the first step is to turn off the system and let the ice melt. Once the coils have thawed, check the air filter, clean the coils, and ensure the airflow is not obstructed.
If your coils freeze again after taking these steps, it could indicate a refrigerant leak or a more serious issue. While thawing the coils and cleaning the system can sometimes solve the problem, if it persists, it’s best to call a professional HVAC technician to inspect the refrigerant levels and diagnose the underlying issue.
When to Call a Professional HVAC Technician
While some air conditioning problems can be fixed on your own, others require the expertise of a trained HVAC professional. Calling a technician is often necessary when dealing with more complex issues or when you’re unable to fix the problem on your own. Below are a few signs that it’s time to call a professional for help.
1. Low or Leaking Refrigerant
Refrigerant is the substance that helps cool the air in your home. If the refrigerant level is low or if there is a leak, your air conditioner won’t be able to cool your home efficiently. Unfortunately, diagnosing and repairing refrigerant leaks is not something you can do yourself, as it involves working with chemicals and handling specialized equipment. Low refrigerant is often a sign of a leak, and the leak must be located and sealed before the system can be refilled. An HVAC professional will have the necessary tools to find and repair refrigerant leaks and recharge the system with the appropriate amount of refrigerant.
2. Electrical Issues
If you notice that your AC system isn’t turning on, is tripping the circuit breaker, or is blowing hot air, the issue could be electrical in nature. Problems with the electrical components of your system, such as the capacitor, compressor, or wiring, can be dangerous to handle on your own. Electrical repairs are often complex and can pose a serious risk of injury or further damage to your system if not done correctly.
When in doubt, it’s always safest to call a professional when electrical problems arise. An HVAC technician has the training and expertise to safely diagnose and repair electrical issues, ensuring that your system is functioning properly and safely.
3. Strange Noises or Odors
Air conditioners are designed to operate quietly, so any strange noise or odor could indicate a serious problem. Grinding, squealing, or rattling sounds might suggest that a part has become loose or is malfunctioning. Additionally, if you notice a musty or burning smell coming from your AC vents, it could be a sign of mold growth or an electrical issue.
While some sounds, like a rattling fan blade, can be fixed by homeowners, other noises or odors require professional intervention. An HVAC technician can inspect your system, locate the source of the noise, and make the necessary repairs. For any smell that indicates a potential fire or electrical hazard, it’s crucial to turn off your system and call a professional immediately.
Weighing the Pros and Cons of DIY vs. Professional Help
When it comes to air conditioning issues, it’s important to know when to tackle a problem yourself and when to call in a professional. Simple issues like clogged filters or thermostat malfunctions are often easy fixes that you can handle on your own. However, problems that involve refrigerant, electrical components, or complex mechanical issues should be left to trained HVAC professionals to ensure safe and effective repairs.
If you’re unsure whether to DIY or call a pro, it’s always better to err on the side of caution. Attempting complex repairs without the necessary expertise can lead to further damage or even injury. By staying proactive with regular maintenance and knowing when to seek professional help, you can keep your air conditioning system running efficiently and ensure that your home stays cool and comfortable all summer long.
