When it comes to keeping your home comfortable, heating and cooling are two of the biggest factors that affect your energy bills. If your system is old or outdated, it could be working much harder than necessary to maintain your indoor temperature. That means wasted energy, higher costs, and less comfort.
At Ashley Brothers Heating & Cooling, we believe that homeowners deserve clear, straightforward information before investing in new HVAC equipment. Whether you’re exploring energy-efficient furnaces in St. Louis or shopping for an energy-efficient air conditioner in Crestwood, MO, understanding what “efficiency” really means can help you make the smartest decision for your home and budget.
Let’s take a closer look at how efficiency ratings work, what makes modern HVAC systems more efficient, and how our team can help you choose and install the best system for your needs.
What Does “Energy Efficiency” Really Mean in HVAC Systems?
In the simplest terms, energy efficiency describes how effectively a furnace or air conditioner converts energy into heating or cooling. The more efficiently a system operates, the less energy it wastes, and the lower your monthly utility bills will be.
For example:
A high-efficiency furnace converts nearly all of its fuel into usable heat with very little waste.
An efficient air conditioner cools your home using less electricity while maintaining consistent comfort levels.
These systems not only reduce energy costs but also have a positive impact on the environment by lowering overall energy consumption.
At Ashley Brothers Heating & Cooling, we specialize in efficient HVAC systems in Crestwood, MO, that meet or exceed ENERGY STAR standards, ensuring top-tier performance and value.
Understanding the Key Efficiency Ratings
When comparing HVAC systems, you’ll encounter several efficiency ratings. These ratings help homeowners understand how much energy a unit uses and how effectively it performs.
1. SEER (Seasonal Energy Efficiency Ratio)
The SEER rating measures how efficiently an air conditioner or heat pump cools your home over an entire cooling season. The higher the SEER number, the more efficient the system.
For example:
Older air conditioners typically have SEER ratings of 8 to 10.
Modern systems start at 13 SEER, with high-efficiency models reaching 20 SEER or more.
A unit with a SEER rating of 18, for example, uses significantly less electricity than a 13 SEER model, translating into lower monthly bills. When shopping for an energy-efficient air conditioner in Crestwood, MO, our team will help you find the right SEER level for your home’s size, layout, and budget.
2. AFUE (Annual Fuel Utilization Efficiency)
AFUE applies to furnaces and boilers and measures how much of the fuel consumed is converted into usable heat. The higher the percentage, the more efficient the furnace.
Here’s a quick breakdown:
A furnace with an 80 percent AFUE converts 80 percent of its fuel into heat, with the remaining 20 percent lost through exhaust.
High-efficiency furnaces can achieve AFUE ratings of 95 percent or higher.
If you’re considering upgrading to one of the energy-efficient furnaces in St. Louis, our experts can explain how AFUE impacts your long-term energy costs and comfort.
3. ENERGY STAR Certification
ENERGY STAR is a nationally recognized symbol of energy efficiency. Systems that earn this certification meet strict performance and energy-saving guidelines set by the U.S. Environmental Protection Agency.
When you see the ENERGY STAR label on HVAC equipment, you can trust that it delivers measurable efficiency and savings compared to standard models. Ashley Brothers Heating & Cooling proudly installs and services ENERGY STAR-certified systems for both heating and cooling.
Features That Make Modern Systems More Efficient
Today’s HVAC systems are designed with advanced technology that helps homeowners save energy without sacrificing comfort. Here are a few of the most important features that contribute to higher efficiency:
Variable-Speed Motors
Traditional systems run at one speed — on or off. Variable-speed systems, on the other hand, adjust airflow and output based on your home’s temperature needs. This allows for consistent comfort and reduced energy waste.

Why Efficiency Ratings Are Worth the Investment
It’s no secret that higher-efficiency systems come with a larger upfront cost, but the long-term benefits make them a smart investment. Here’s why:
1. Lower Energy Bills
An energy-efficient system uses less electricity or fuel, which directly reduces your monthly utility costs. Over time, these savings can easily offset the initial installation price.
2. Increased Comfort
Efficient systems maintain consistent temperatures, reduce humidity, and provide quieter operation. Variable-speed motors and smart controls also eliminate frequent temperature swings.
3. Extended Equipment Life
Systems that operate efficiently experience less strain and wear, leading to longer lifespans and fewer breakdowns.
4. Eco-Friendly Operation
By using less energy, efficient HVAC systems reduce your home’s carbon footprint and support environmental sustainability.

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.

As the temperatures begin to rise and the cold winter months fade away, it’s time to start thinking about getting your air conditioning system ready for the warmer season. Spring is the perfect time to schedule an AC tune-up, ensuring your unit will keep you cool and comfortable throughout the hot summer months. Just as you would prepare your car for the road or your home for the winter, your air conditioner requires regular care to run efficiently. Over time, even the most reliable AC units can develop issues, so staying proactive with AC maintenance is essential for ensuring optimal performance. If you’re unsure whether your AC is ready for spring, here are some signs that it might be time for a tune-up.
Why AC Maintenance Matters
AC maintenance is not just a luxury but a necessity to keep your system running at peak efficiency. When your air conditioner is well-maintained, it operates more effectively, using less energy and providing cooler air while maintaining a lower energy bill. Regular inspections also help you catch minor issues before they become major problems, preventing expensive repairs or even the need for a full AC installation down the road. Just like how you wouldn’t drive your car for years without a tune-up, you shouldn’t let your AC go without regular care. Ensuring it runs smoothly during the hot months requires you to stay ahead of wear and tear and attend to issues as soon as they arise.
Signs That It’s Time for an AC Tune-Up
Many homeowners overlook the need for AC maintenance, only realizing the importance when their system fails unexpectedly. However, there are a few telltale signs that can alert you that your AC might need a tune-up before it breaks down completely. One of the first indicators is poor airflow. If you notice that the air coming from your vents is weak or inconsistent, it may be a sign of a clogged air filter, a malfunctioning fan, or a more serious internal issue. This reduced airflow can significantly affect your system’s ability to cool your home efficiently, leading to higher energy costs.
Another common sign that your AC might need a tune-up is the presence of strange noises. AC systems are designed to run quietly in the background, but if you hear unusual sounds such as banging, rattling, or screeching, it could indicate loose or broken components within the unit. These noises are usually a sign that something is wrong and should be addressed by a professional before the problem worsens. Additionally, if you notice any strange odors emanating from your air conditioner, such as a musty or burning smell, it could signal mold or wiring issues that require immediate attention.
Your air conditioning system’s ability to maintain a consistent temperature is another key indicator of its health. If you find that certain rooms are significantly warmer than others or that your thermostat seems to be reading incorrectly, this could be an issue with the unit’s calibration or its cooling function. You might also notice that your system cycles on and off more frequently than usual. This “short cycling” can be a result of an overworked compressor or a clogged condenser coil and should be looked at to prevent damage.
The Importance of Professional AC Inspections
While DIY troubleshooting can sometimes help identify minor issues with your air conditioning system, it’s essential to schedule professional AC inspections regularly to ensure that your system is operating at its best. A trained technician will be able to perform a comprehensive check of your entire system, inspecting components that might be difficult for the average homeowner to reach or assess. During an inspection, the technician will clean the coils, check for refrigerant leaks, examine the ductwork for leaks or blockages, inspect the thermostat, and assess the overall performance of the system.
By having your AC professionally inspected, you’re also ensuring that it remains under warranty. Many manufacturers require regular maintenance for the warranty to remain valid, and neglecting these inspections could lead to costly repair bills down the line. Additionally, an inspection can help you identify any potential hazards, such as electrical problems or faulty wiring, which could pose a safety risk if left unaddressed.
Scheduling AC inspections and tune-ups also allows you to plan for future repairs or upgrades. If your system is outdated or showing signs of wear, a technician can advise you on whether it’s time for an AC installation. By catching these issues early, you can avoid expensive breakdowns during the summer when you need your AC the most.
The Benefits of Regular AC Tune-Ups
Regular AC tune-ups are essential not only for improving the performance and longevity of your system but also for saving money in the long run. One of the key benefits of routine maintenance is that it can significantly reduce the chances of a system breakdown during the hot months. As your AC gets older, the parts inside it start to wear down, and regular tune-ups ensure that these parts are working efficiently and not causing unnecessary strain on the system. When everything is running as it should, your AC can cool your home more efficiently, reducing your monthly energy bills and the need for costly repairs.
Furthermore, an efficiently running AC system provides a more comfortable home environment. A system that’s well-maintained maintains optimal cooling throughout your home and prevents temperature fluctuations that can make it harder to find a comfortable spot. With routine inspections and tune-ups, you’re also contributing to better air quality. Clean filters and coils reduce the amount of dust, dirt, and allergens circulating through your home, which can improve the health and comfort of your family.
Perhaps one of the most significant benefits of AC maintenance is extending the lifespan of your system. Air conditioners are a significant investment, and regular care can help ensure that your unit lasts for years, delaying the need for an AC installation. If you neglect maintenance, you may find yourself needing a new unit sooner than expected, which can be a costly and unnecessary expense.
Preparing for an AC Installation
If your AC system is showing significant signs of aging or has failed to function properly despite regular maintenance, it may be time to consider an AC installation. As the summer months approach and temperatures rise, the last thing you want is to be left without a working air conditioner. If your system is over ten years old, it may be more cost-effective to replace it rather than continuing to repair it.
Modern air conditioning units are more energy-efficient than older models, meaning a new installation could actually save you money in the long run. Additionally, advancements in technology have made new systems quieter and more environmentally friendly. If you find yourself calling for AC repairs more frequently or your energy bills are climbing, it may be a sign that an upgrade is necessary. A professional technician can help you evaluate the best options for your home and budget, ensuring you invest in an AC system that will keep your home comfortable for many years to come.

Troubleshooting and Solutions
Check Refrigerant Levels
If you suspect low refrigerant levels, have a qualified technician inspect and recharge the system as needed. It’s crucial to address refrigerant leaks promptly to prevent further damage to the air conditioning system.
Clean or Replace Air Filters
Inspect air filters regularly and clean or replace them as needed to ensure optimal airflow and system efficiency. Dirty or clogged air filters can impede airflow and cause the air conditioner to blow hot air.
Schedule Professional Maintenance
Regular maintenance by a qualified technician is essential for keeping your air conditioning system in top condition. Schedule annual inspections and tune-ups to identify and address any potential issues before they escalate.
Repair or Replace Faulty Components
If your air conditioner is experiencing compressor issues, electrical malfunctions, or other mechanical problems, it’s crucial to have these repairs addressed promptly by a professional technician. In some cases, component replacement may be necessary to restore proper functioning.
Conclusion
A malfunctioning air conditioner that blows hot air can be a frustrating and uncomfortable experience, especially during hot summer days. By understanding the common reasons why air conditioners blow hot air and taking prompt action to address any issues, you can ensure that your home remains cool and comfortable year-round. Whether it’s low refrigerant levels, dirty air filters, or compressor problems, don’t hesitate to seek professional assistance to diagnose and repair the problem. With proper maintenance and care, you can keep your air conditioning system running smoothly and efficiently for years to come.
