Ductless Vs. Central AC: Which Cooling System Fits Your Home Best? 

Summers in Louisiana are characterized by long spells of heat and humidity, which should be well familiar to local residents and frequent visitors. During these sweltering—and sometimes unforgiving—periods, having access to a dependable air conditioning system is a must.  

In homes across Baton Rouge, Gonzales, Prairieville, and Denham Springs, residents often have to decide between replacing their existing systems with a brand-new central unit or switching to a ductless solution.  

Each of these choices offers its own unique set of advantages and trade-offs, so cost isn’t the only factor that they should consider. Other factors that come into play include comfort, energy use, and the overall design of the home. All of these play an important role in determining comfort level and energy costs.  

Here, we provide a detailed ductless vs. central AC comparison to give you a better understanding of how each system works. You can then decide which option will fit your household best when you need to shop for the best cooling system Baton Rouge has to offer. 

How Central AC Works 

 Central AC systems cool the air via the main system unit and distribute it through a network of ducts. They typically have a compressor, a condenser, and an evaporator coil, all of which work together to remove heat and humidity from the air. The cool air is then circulated throughout the home.  

Central AC systems are particularly effective in larger Baton Rouge houses where whole-home comfort is usually desired. The downside is that these systems generally require more intensive installation work, especially if the homes don’t have existing ductwork.  

This is less of an issue in neighborhoods such as Gonzales and Prairieville, where many of the homes were designed with ducts. With Central AC systems, it’s possible to have consistent cooling in every room, which makes it the ideal solution in areas where temperatures can soar into the 90s and humidity levels remain consistently high during summer. 

How Ductless Mini-Splits Work 

 Unlike central systems, ductless mini-splits don’t require ducts. Instead, they’re fitted with a single outdoor condenser connected to multiple wall- or ceiling-mounted air handlers. 

 Each of these air handlers is intended to cool a specific room or zone. Therefore, you get the benefit of targeted comfort where you need it most. 

 Ductless mini-splits are notable for their efficiency and versatility. Even the U.S. Department of Energy lauds their benefits in its guide on Energy.gov: Ductless Mini-Splits.  

 In older Baton Rouge homes where installing new ductwork is impractical or aesthetically undesirable, these systems are often the preferred option. Furthermore, they allow homeowners to cool only the rooms they occupy, which can help manage energy costs. For families in communities like Denham Springs, ductless AC in Baton Rouge is the most practical solution. 

Benefits of Central AC 

 Central systems are the preferred choice for homeowners who require whole-home integration. If you’re looking for consistent comfort with minimal visual impact, this is the way to go. Some of the benefits of central AC are:  

• Whole-home comfort: Provides even temperature control in every room. 

• Better aesthetics: Doesn’t require wall-mounted units that interfere with your interior design. 

• Higher home resale value: Can be an attractive selling point for prospective home buyers. 

• Integration: Easily connects with existing ducts—even heating systems! 

As mentioned previously, the downside is that installation and replacement of these systems can be costly. On the other hand, the seamless experience and property value advantages can offset these costs. For traditional layouts and larger homes, central AC is the clear winner. 

Benefits of Ductless AC 

 Given the spiraling cost of cooling a home, ductless HVAC vs. central air has become a common debate. For efficiency and flexibility, ductless systems are pretty hard to beat, offering the following advantages:  

• Energy efficiency: Reduces energy expenses by cooling only the rooms you use. 

• Easier installation: Doesn’t require intensive and potentially disruptive installation. 

• Flexible comfort: Individual room control allows for diverse cooling requirements. 

• Cleaner air quality: Practically no dust or debris buildup. 

Admittedly, having multiple indoor units can indeed increase your upfront expense. Even so, the long-term energy savings and comfort even out the cost over time. If you’re looking for modern, adaptable cooling, ductless AC warrants a close look. 

How to Decide Which Is Right for You 

 The choice between ductless and central cooling often comes down to your interior layout, long-term plans, and lifestyle preferences. When deciding which option is right for you, consider the following factors:  

 Central systems are the more affordable options over the long term, especially if you already have a duct system in place. That being said, ductless systems can also result in lower energy costs by allowing targeted cooling. 

 What about homes that don’t already have ducts? Or what if you have a traditional home where a typical duct system would be unsightly? Ductless systems are the clear solution because they don’t require major renovations. 

 In terms of quiet operation, both types of systems are pretty evenly matched. However, some ductless systems have a slight advantage with their near-silent indoor units. 

 If you’re concerned about preserving your home’s resale value, Central AC tends to be more appealing to traditional buyers. On the other hand, ductless systems are often preferred by energy-conscious buyers.

How Humidity Affects Your Air Conditioning Efficiency In Louisiana 

Louisiana summers are notorious for sticky, oppressive heat. In Baton Rouge, residents may notice their air conditioners running constantly but failing to maintain a comfortable temperature.  

 What some might not realize is that high moisture levels significantly reduce cooling efficiency. This can make homes feel warmer than the actual temperature.  

 Understanding humidity and AC efficiency can help homeowners achieve consistent temperatures, prevent moisture-related damage, and lower energy costs. You may also want to read up on EPA: humidity and indoor air quality reports to receive guidance on maintaining proper moisture levels while optimizing energy use. 

The Relationship Between Humidity and Cooling Efficiency 

Humidity directly affects how air conditioning systems perform. In Baton Rouge, the humidity often makes indoor air feel several degrees hotter, forcing AC units to run longer cycles.  

In many homes around Denham Springs, trapped moisture can linger in walls and ceilings, creating damp conditions that persist even when the AC runs continuously. High indoor humidity reduces the system’s ability to remove heat efficiently, leading to uneven cooling and increased wear on the unit. 

Air conditioning systems are primarily designed to remove heat, not moisture. When air contains excess water vapor, the AC has to work harder to condense the moisture from the air. This process slows cooling and can leave some areas of the home warmer than others. For example, a home in Gonzales may feel comfortable near vents while corners remain hot and sticky. 

Regular air conditioning services focused on humidity control can help maintain AC performance, protect equipment from overworking, and provide consistent indoor comfort. Homeowners who understand this relationship can take proactive steps to prevent humidity from leading to more serious problems. 

Signs of High Humidity in Your Home 

Humidity control is crucial in preventing structural damage, mold growth, and rising energy costs. Apart from exploring solutions such as AC upgrades, you may also want to consider purchasing a dehumidifier, a Baton Rouge essential.  

High indoor humidity isn’t always obvious. But it can manifest in ways that signal problems. Signs of excessive humidity include: 

• Condensation on windows or mirrors: Persistent moisture indicates too much indoor humidity. 

• Musty odors: Mold or mildew produces a noticeable scent that lingers in rooms. 

• Warping or damage to wood: Flooring, cabinets, and furniture may swell or crack from moisture. 

• Allergic reactions: Dust mites and mold spores trigger sneezing, coughing, or other respiratory symptoms. 

• AC not cooling: Humidity can be worsened by systems struggling to lower temperatures despite running continuously. 

Recognizing these signs early allows homeowners to install a dehumidifier or schedule professional service to correct humidity issues. Early action prevents minor problems from escalating into costly repairs, protects indoor air quality, and maintains energy efficiency. 

How High Humidity Increases Energy Bills 

Excess moisture in the home can dramatically increase energy consumption. In Baton Rouge, one family reported a 25% rise in summer utility bills. Their older AC system had to work overtime to remove both heat and humidity, leaving some rooms warm and others cool but damp. 

A Prairieville home experienced frequent AC cycling due to high humidity. Short, repeated cycles increased electricity use while failing to maintain consistent indoor temperatures. The homeowner resolved the problem with a seasonal HVAC tune-up and strategic dehumidifier placement, lowering monthly bills while restoring comfort throughout the home. 

Humidity also accelerates wear and tear on AC systems. Units that operate in high-moisture conditions are more likely to develop mechanical issues, which reduces their lifespan and increases repair costs.  

Solutions for Controlling Humidity 

Controlling Baton Rouge humidity requires a combination of equipment, service, and preventive strategies. Homes in Denham Springs, Gonzales, and other areas benefit from integrated approaches that target both heat and moisture. Recommended solutions include: 

• AC upgrades: Modern systems handle high humidity more efficiently, delivering consistent cooling and reducing energy bills. 

• Indoor air quality enhancements: HEPA filters, UV lights, and ventilation systems help manage airborne moisture and allergens. 

• Dehumidifiers: These reduce indoor moisture, lessening strain on the AC and improving comfort. 

• Improved ventilation: Ensures proper airflow, preventing stagnant, humid areas that promote mold and mildew growth. 

• Seasonal HVAC tune-up: Detects issues early, ensures peak system performance, and maintains long-term efficiency. 

Implementing these solutions allows homeowners to address high humidity comprehensively. Combining upgrades, professional service, and dehumidification ensures energy-efficient, comfortable homes year-round.

 AccuTemp is committed to supporting your goals to improve energy efficiency and reduce your energy bills. From simple habits to strategic upgrades, these proven methods will help improve Baton Rouge HVAC efficiency while protecting your home investment. 

Why Energy Bills Spike in Louisiana 

Louisiana’s climate is likely the single most significant factor contributing to the region’s high energy costs. Baton Rouge experiences hot, humid summers that last from May through October. During this period, it isn’t unusual for temperatures to climb into the 90s.  

In this harsh and unforgiving climate, air conditioners are forced to work longer hours, resulting in a significant increase in energy use. For many households, the main challenge is how to lower their AC bill without compromising indoor comfort. 

In Gonzales, the combination of heat and rapid population growth has increased the demand for reliable cooling solutions. Many of the newer homes in the area are pretty large, so more energy is required to maintain a consistently cool interior space. Without energy-efficient cooling strategies, monthly bills can easily rise faster than expected. 

Prairieville faces similar challenges. The high humidity levels in the area require air conditioners to work harder to reduce moisture inside, which increases utility expenses. Consequently, homeowners often wonder how to keep their AC bill low during the peak summer months, especially when children are home from school and indoor usage increases. 

Denham Springs’ blend of older and newer housing presents another issue. Many of the area’s older homes have outdated insulation or inefficient ductwork. This leads to air loss that puts extra strain on the HVAC system. For the area’s residents, applying common AC energy savings tips is essential to keep cooling affordable. 

Each of these communities highlights a different aspect of why energy costs rise in Louisiana. But the underlying issue remains cooling systems must work harder to maintain comfort in challenging conditions. 

Quick Tips to Improve Energy Efficiency 

The good news is that there are many immediate steps homeowners can take to see better performance and lower bills. Making these minor adjustments to daily habits can result in noticeable energy savings:  

• Adjust thermostat settings: Keep temperatures around 78°F when home and a bit higher when away. Smart thermostats make it easier to maintain consistent comfort. 

• Improve insulation: Adding attic insulation or sealing air leaks reduces strain on the system. 

• Use ceiling fans: Circulating air makes rooms feel cooler at higher thermostat settings. 

• Schedule HVAC maintenance: Professional inspections keep equipment running at peak efficiency. 

• Close blinds during peak sun: Reducing solar heat gain helps maintain a cooler indoor environment. 

These adjustments provide near-immediate methods for more energy-efficient cooling. Although they may not be replacements for professional solutions, they serve as practical ways for most households to reduce unnecessary energy waste. 

The Role of Regular HVAC Maintenance 

Professional service is one of the most effective ways to control costs. Just as cars need regular tune-ups, air conditioners benefit from scheduled care. Routine HVAC maintenance helps identify minor problems before they become expensive repairs, ensuring the system operates at its designed capacity. 

For Baton Rouge households, regular maintenance also extends the life of equipment. A well-maintained system doesn’t have to work as hard, which reduces energy consumption. Services such as coil cleaning, refrigerant checks, and duct inspections directly contribute to Baton Rouge HVAC efficiency and lower operating costs over time.

As the temperatures drop, the idea of no heat is a chilling thought. A simple furnace malfunction is one thing—a furnace not igniting burners is another. To help you maintain a safe living space throughout the cold months, we have created an outline of the most common reasons a furnace may stop igniting and ways to respond to the issue.

Top Causes of Furnace Ignition Issues

There are a variety of reasons as to why a furnace can exhibit ignition issues. Considering furnaces contain a series of internal components and are connected to other home systems, ignition issues can stem from numerous directions.

Before we go in-depth into each cause, it is important to call an emergency plumber if you smell gas in your house.

Now, here are the top causes of furnace ignition issues:

1. Gas Line Issues

Furnace not igniting burners? One of the most common reasons behind this issue is a blocked or clogged gas line. When the gas line is blocked or clogged, the furnace is unable to draw the natural gas needed to start and provide heating. The best solution for this problem is resorting to professional help. A certified heating expert can determine if any obstructions are causing the issue.

2. Defective Thermostat

Another potential culprit might not even be the furnace, but the thermostat. A faulty thermostat can have issues communicating with the furnace, leading to incorrect heating or no heat at all. Have a technician inspect the thermostat and, if it’s indeed defective, replace it to restore heating.

3. Clogged Furnace Filter

A dirty and clogged air filter can lead to several furnace problems, including ignition. Over time, the air filter becomes clogged due to the buildup of dirt and dust. The best method to prevent this is by changing the filter around every 90 days. This way, the furnace can work efficiently and supply sufficient heating.

4. Malfunctioning Igniter or Pilot Light

Has your furnace suddenly stopped igniting? It could be a failed igniter or the pilot light has gone out. You’ll need to determine which one isn’t working. If you hear a clicking noise but the furnace burners are not lighting, the problem most likely is related to the igniter. If the furnace runs for a couple of minutes and then shuts off, the pilot light may need replacement. Either way, this issue calls for professional assistance.

5. Dirty Gas Burners

Gas burners collect dirt and debris over time, limiting even burning at the proper height. This causes the thermostat to adjust to a lower temperature, forcing the heating system to work harder and even create a higher amount of carbon monoxide in the system.

If your furnace is not igniting or is heating your house inefficiently, the good news is that dirty gas burners are relatively easy to clean by a professional. A professional can blow compressed air through each one and wipe the outside with a brush or rag. In addition, you can also increase the amount of dusting you do to better keep dirt out of the furnace.

6. Damaged Flame Sensor

A furnace having difficulty staying lit could be the result of a damaged flame sensor. The flame sensor is a key component that is responsible for detecting the presence of the flame. A faulty flame sensor can lead to overheating and burnt parts. You will need professional attention to fix this issue but you can start by cleaning the air vents for your furnace and unplugging the unit.

7. Draft

A strong draft in your basement or attic can also prevent the pilot light from lighting. If high winds are present, the draft can potentially become more problematic. The pilot may also fail to light if your furnace has a broken or malfunctioning draft motor. Draft motors rely on drawing air from a chimney or vent and if there is a blockage preventing incoming air, the igniter won’t light and you might hear a faint humming.

Enlist the help from a heating expert if your furnace is not igniting. A professional will be able to accurately diagnose the issue and provide you with the necessary solution.

8. Loose or Damaged Electrical Components

For operation, furnaces depend on multiple electrical connections and components. A furnace not igniting the burners could be related to loose or damaged electrical components and connections. A licensed technician can inspect your unit for any loose connections or signs of damage. If there is damage, a professional will safely tighten or fix the electrical connections.

9. Tripped Circuit Breaker

Your furnace will fail to start if there is no power being relayed to it, making a tripped circuit breaker another possibility. Locate your circuit breaker and see if it’s been tripped. If it has, reset it and see if the furnace starts again.

10. High-Limit Switch Activation

The furnace will fail to turn on if its high-limit switch is activated—the feature that will turn off the furnace if it overheats. The high-limit switch is commonly activated when there is restricted airflow. Check the vents and ductwork for obstructions.

11. Control Board Problems

Another electrical-based issue that can prevent the furnace from igniting is the control board. This board controls various functions and when its components experience issues, ignition can fail to start. Since this is an electrical issue, turn to the help of a professional.

12. Clogged Exhaust Vents

Furnaces come with exhaust vents to expel harmful gases and when the vent is blocked, ignition can fail to start. A certified professional can inspect the vent for obstructions like birds nests, debris, or ice and clear them.

There are several noises homeowners hear when their furnace is in operation. A pop or click when turned on and a dull hum when turned off are completely normal. However, what happens when you hear more intense noises? If your furnace is making odd noises, there is a possibility something is wrong.

We understand the level of panic a noisy furnace can cause. These loud and unpleasant noises coming from your furnace could be the result of many factors or causes. Let’s break down the potential reasons for these furnace noises and what you can do about them. This will allow you to put these annoying noises behind you and enjoy an efficient furnace once again.

Common Causes of Strange Furnace Sounds

Hearing strange noises from your furnace is understandably frustrating. You’re also probably wondering why your furnace is making sounds in the first place. Let’s look over some of the common causes of a noisy furnace or heat pump.

1. Damaged Blower Motor

One of the likely causes behind a noisy furnace is a bad blower motor. The blower motor is responsible for pushing warm air out of the furnace and into the air ducts. Since the blower motor has several parts for operation, proper upkeep becomes even more important. A blower motor’s bearings can overheat, experience wear and tear, and simply age out.

What does a bad blower motor sound like? A damaged blower motor can emit several sounds like a high-pitched squeal, rattling, screeching, or even a whistling sound.

2. Dirty Gas Burners

If your furnace’s gas burners become too dirty, they can delay the system’s ignition for gas buildup within the combustion chamber. This occurrence leads to an alarming bang or explosion sound soon after ignition. The best way to prevent this from happening is to make scheduled inspections and cleanings a staple for your furnace.

3. Cracked Heat Exchanger

Another reason your furnace is making noise could be the result of a cracked heat exchanger. Heat exchangers are a thin metal shield between the blower and combustion chamber that prevents gas and combustion fumes from escaping.

While a loose component or panel in the furnace can lead to rattling noises, the persistence of this particular sound could be a sign of a cracked heat exchanger. A cracked heat exchanger should be addressed immediately to avoid carbon monoxide poisoning.

4. Loose Parts

A furnace system has a plethora of moving parts, components, and panels. Did your furnace start making strange noises when you turned it on at the beginning of the winter season? Loud ratting noises can be caused by loose parts in your heating system.

For a properly functioning furnace, all connections and parts must be tightened accordingly. Routine heating maintenance and system checkups allow technicians to tighten components and lubricate moving parts, preventing further issues.

5. Defective Ignition System

A furnace’s ignition system is responsible for creating the combustion needed for producing heat. When the ignition system becomes defective due to a broken sensor, faulty pilot light, or a malfunctioning ignition board, it’s common to hear a clicking sound if it fails to light.

If you notice this clicking sound, make sure to contact AccuTemp immediately so our technicians can fix the issue and get your furnace up and running again.

6. Loose Fan Belt

If your furnace has a belt-driven motor it’s possible that it can become loose and create squealing or screeching noises over time. When this happens, an HVAC technician will have to either adjust the belt or replace it with a new one.

Additionally, other components like shaft bearings can also produce the same noise. This is the result of loose components coming into contact with each other, which can also lead to bigger issues if left unaddressed. Whether it’s a thrown-off fan belt or loose shaft bearing, reach out to an HVAC expert to resolve the issue with precision.

7. Malfunctioning Blower Wheel

Even as a contributing component of the blower motor, an issue with the blower wheel creates a much different sound. If a blower wheel were to come loose, it would cast a large clanking sound as it comes into contact with the blower house casing. If you hear this noise, turn off the furnace to prevent future damages and contact an HVAC official to determine if repairs or heating replacement is the necessary route.

8. Electrical Issues

Maybe you’ve noticed a buzzing or humming noise. A dull hum from your furnace is normal, but if these sounds are especially loud, there could be an electrical issue within the furnace.

Various electrical issues within a furnace that could lead to these noises include:

• Old blower motor
• Faulty inducer motor
• Malfunctioning transformer
• Failing blower motor capacitor

Different Types of Furnace Noises and Issues

Let’s look at the different types of furnace noises and issues and directly pair them with each other. This will give you a better understanding of which type of noise is probably linked with a certain issue.

Scraping Noises

The presence of scraping noises most likely is related to the blower wheel. When the blower wheel is broken it can emit this sound, or when it’s loose it can grind up against the furnace’s other components.

Squealing Noises

Squealing noises are either the cause of issues with the blower motor bearings or the furnace’s belt. This type of noise can most likely be fixed with the tightening and lubrication of the blower motor bearings and an adjustment or replacement of the belt.

Whistling Noises

Whistling noises are also related to the blower motor. A high-pitched whistling sound can develop due to airflow issues with the blower motor and can be fixed by cleaning or replacing the air filter.

Banging Sounds

Banging sounds can be the result of:

• Ductwork issues
• Dirty gas burners
• Delayed ignition
• Cracked heat exchanger

Rattling Noises

If you’re hearing rattling noises, it’s commonly related to a loose panel. Panels, doors, and parts can all become loose over time and can be addressed properly with routine maintenance.

Buzzing Sounds

Buzzing or humming sounds within the furnace are commonly associated with electrical issues. Electrical issues with the fan or motor in your furnace are known to emit these noises and should be addressed by a professional.

Clicking Noises

In the event of clicking noises, the furnace is probably failing to complete its ignition process. Ignition issues can be linked to dirty gas burners, a damaged flame sensor, or a faulty ignition board or valve.
