When it comes to air conditioners, one size does not fit all. There are various types of air conditioners that cater to diverse cooling needs. Even if you’re replacing your existing air conditioner, it’s helpful to understand the pros and cons to help you make an informed decision about the best cooling solution for your space.
Central air conditioning systems are a popular choice for those seeking a whole-house cooling solution. In fact, according to the US Energy Information Administration, 75% of homes have central air conditioners as their cooling system. These systems work by distributing cool air throughout your entire home via a network of ducts and vents. They offer consistent and efficient cooling, ensuring a comfortable indoor environment during the scorching summer months.
One of the primary advantages of central air conditioning systems is their ability to cool large areas effectively. With the air conditioning compressor located outside the house, the cool air is evenly distributed through ductwork, reaching every room in your home. This eliminates the need for multiple individual units, providing a more uniform and reliable cooling experience.
Central air conditioning systems also offer the flexibility to customize temperature settings for different zones within your home. By installing zone control systems, you can adjust the cooling levels in specific areas according to your preferences, enhancing energy efficiency and personalized comfort.
While central air conditioning systems may require professional installation and initial investment, their long-term benefits, including consistent cooling, improved indoor air quality, and potential energy savings, make them a reliable and efficient choice for many homeowners.
Ductless mini-split systems offer versatile and efficient cooling solutions, consisting of an outdoor unit and one or more indoor units, connected by refrigerant lines. With easy installation and customizable zone control capabilities, ductless mini-splits are a popular choice.
One of the key advantages of ductless mini-split systems is their versatility. Each room or area can have its own individual air handler, allowing for personalized temperature control and independent cooling zones. They are also typically a less expensive choice compared to central air conditioning systems. Ductless mini-split systems are considered a high-efficiency option because they minimize energy losses associated with ductwork, and can be turned on and off independently in different areas.
If you decide a ductless mini-split system is the best type of air conditioner for your home, consider the number of indoor units required, the cooling capacity of each unit, and the overall system efficiency. Seeking guidance from HVAC professionals can help determine the best configuration and ensure proper installation.
Despite the name, heat pumps offer both cooling and heating capabilities. During the summer, a heat pump pulls the heat from your indoor air and transfers it outdoors in order to cool your home. During the winter, the process is reversed, and heat is extracted from the outdoor air and circulated indoors.
Heat pumps are known for their energy efficiency. Since they use electricity to move heat rather than generate it, they consume less energy and help to reduce your carbon footprint. Because they don’t use coolant or a dedicated heat source, heat pumps are typically the best type of air conditioning and heating system for homeowners living in milder climates, where extreme temperatures are less common.
When it comes to AC options for homes, window air conditioners and portable units offer convenience and flexibility.
Both window air conditioners and portable units provide targeted cooling for specific areas and are relatively easy to install. They are ideal for spaces where permanent installation is not an option or for renters who need a portable cooling solution.
Available to purchase on your own at most home improvement or appliance stores, window air conditioners and portable AC units are sized based on how many square feet you’d like to cool and have varying energy-efficiency ratings. For those looking to cool a larger space, window air conditioners are not the most efficient choice, as you’ll need many units to achieve the same cooling power as a central air conditioning system.
Air conditioner sizing is crucial for efficient cooling and energy savings. An undersized unit will struggle to cool your home, while an oversized one will cool too quickly, causing humidity issues and frequent on-off cycles, leading to increased energy consumption.
When choosing an air conditioner, you first need to understand the factors which can influence your cooling needs:
While it may be tempting to make an estimation based on room size alone, it’s essential to seek the help of an AC installation professional to help you calculate the best-sized air conditioner.
AC installation contractors take into account the various factors that can’t be summed up in a simple math equation. A local contractor will also be aware of how the local climate impacts the way an air conditioner will function in your home. After a thorough assessment of your home, they’ll be able to provide you with an air conditioner that matches your space’s cooling requirements precisely.
Additionally, AC professionals have the knowledge and experience to recommend energy-efficient models that will not only provide effective cooling but also help you save on your energy bills. They can guide you through the selection process, considering factors like SEER ratings (Seasonal Energy Efficiency Ratio) to identify air conditioners that meet high energy efficiency standards.
A quality air conditioner goes beyond cooling; it brings comfort, energy efficiency, and cleaner indoor air. When choosing the best air conditioner for your home, consider these key features:
Energy efficiency is a key consideration when selecting an air conditioner, as it not only reduces your environmental impact but also helps you save on energy costs. There are various ratings and factors to consider when evaluating the energy efficiency of different models. By understanding energy efficiency, you can choose the best air conditioner to promote sustainability and keep your cooling expenses in check.
The key to buying an energy-efficient air conditioning system is to reference the SEER (season energy efficiency ratio) rating. The SEER rating of a unit is the cooling output during a typical cooling season divided by the total electric energy input during the same period. The higher the unit’s SEER rating, the more energy-efficient your air conditioner system is.
When buying an air conditioner, look for a model with a high-efficiency SEER rating. Many new systems have SEER ratings as high as 26. Most air conditioner systems have a yellow and black “energy guide” sticker on the outside unit where the AC SEER rating is listed. If your air conditioner system is missing this sticker, look up your model’s serial number or call your manufacturer for more specific information.
When it comes to choosing the best air conditioner, energy efficiency goes beyond just the SEER rating.
Look for advanced features that can play a role in energy efficiency. Units with variable-speed compressors or dual-stage cooling can adjust their output based on your cooling demands, preventing unnecessary energy waste. And if you opt for an air conditioner with a smart or programmable thermostat, you gain precise temperature control, allowing you to optimize energy usage according to your schedule and preferences.
The overall design of the air conditioner is also important. Look for units with well-insulated cabinets, efficient fan motors, and improved airflow management. These features help to minimize energy losses and reduce your energy consumption. Choosing an air conditioner with high-quality construction and design ensures that you get the most efficient cooling performance while keeping your energy bills in check.
When choosing the best air conditioner, the upfront cost is often the first thing that comes to mind. However, there are many other things that come into play when considering the investment in an air conditioning system.
There are many rebates and incentives offered by manufacturers, energy companies, and government programs. Take advantage of these opportunities to maximize your savings and contribute to a greener environment!
These incentives can help offset the initial costs of purchasing and installing an energy-efficient air conditioner. When purchasing a new air conditioning system, do your research and ask your HVAC contractor about federal and local programs that may be available. With newer initiatives by the EPA, you can save hundreds, or even thousands, by choosing an air conditioner with a high-efficiency rating.
The installation and maintenance requirements of an air conditioner play a significant role in determining the ideal choice for your cooling needs.
Different types of air conditioners may have specific installation requirements. For example, central air conditioning systems typically require ductwork installation, while ductless mini-split systems need proper placement of indoor and outdoor units. By consulting with HVAC professionals, you can determine which air conditioning system is most compatible with your home’s existing infrastructure, ensuring a seamless and effective installation.
Regular maintenance is essential to keep your air conditioner running smoothly and efficiently. Some types of air conditioners require more frequent and involved maintenance than others. For instance, central air conditioning systems typically require regular filter changes, air conditioner coil cleaning, and professional tune-ups to ensure optimal performance. Ductless mini-split systems and window air conditioners also require filter cleaning or replacement.

Word of mouth, reviews, and certifications are excellent barometers for an AC contractor’s efficiency and reliability.
The journey to finding the perfect air conditioner isn’t just about an immediate investment, but also about considering long-term energy savings and environmental impact. Making an informed decision about the best air conditioners isn’t merely about cooling efficiency, but also about understanding the impact of your choice on the environment and your future energy bills.
Always remember, choosing an energy-efficient model could mean lower energy consumption and reduced carbon footprint, all while maintaining the comfort and cool you desire. From central air conditioning systems to heat pumps and ductless systems, there are AC options for homes to meet everyone’s needs.
Choosing the right size HVAC unit for your home can have a large impact on year-round comfort, energy efficiency, and the lifespan of your equipment. There is a process to determining the proper unit size for your space – and bigger isn’t always better. There are drawbacks to installing an improperly sized system – whether it’s too large or too small.
An air conditioner that’s too small can lead to overworked equipment that runs constantly, raising your utility bills and rarely reaching or maintaining desired indoor temperatures. Along with higher energy costs, an undersized system can also cause uneven cooling throughout your home.
While an oversized system will reach desired indoor temperatures quickly, this causes them to cycle on and off frequently. Repeating this cycle too often wastes energy and causes undue wear and tear on the unit. This can lead to a shortened equipment lifespan and higher maintenance costs. Plus, with air flow happening for only part of the day, humidity can rise making the home uncomfortable and possibly leading to harmful conditions like mold or mildew build-up.
There are three primary types of HVAC systems: split-system, ductless and packaged units.
Split-system Air Conditioners
The most common of the three, a split-system is an outdoor air conditioner or heat pump and an indoor furnace or air handler combo. The indoor and outdoor components work together to control the temperature and humidity levels within your home. A split-system provides a good balance of efficiency, budget, and low noise level.
Ductless Systems
A ductless system, often called a mini-split, consists of a single outdoor unit directly connected to one or more indoor units that distribute air throughout the home. Ductless systems require minimal modifications to your space to install and are often used to cool single rooms or small spaces. They can also be installed using multiple independent indoor units for environments where different temperatures are desired in different spaces.
Packaged Units
Packaged unit systems consist of a single outdoor unit that incorporates all of the mechanical components in one. A packaged system connects directly to your home’s ductwork, distributing heated and cooled air directly. Packaged units are great for homes with limited interior space or that lack the attic or basement typically needed for a furnace or air handler.
Before determining the specific system size that works for you, it’s good to learn about the efficiency and cooling capacity ratings associated with type is system you plan to install. Understanding Seasonal Energy Efficiency Ratio (SEER2) and capacity ratings - measured in tons or BTUh (British Thermal Units per hour) - can help you make a more educated purchasing decision.
What is a SEER2 rating?
A SEER2 ratio is a calculation used to measure the energy efficiency of a specific HVAC system. A unit’s SEER2 rating is reached by dividing its cooling output (over an average cooling season) by the total amount of energy used. The final number reflects a systems maximum efficiency rating under ideal conditions. Systems that use energy more efficiently have a higher SEER2 ratio. Most common systems have a rating between 14 and 16 SEER2, while more expensive, high-efficiency systems can have ratings as high as 22 SEER2.
What is a tonnage/BTUh rating?
Tonnage or BTUh ratings indicate the amount of energy it takes an air conditioner or HVAC system to remove heat from a home in a 1-hour period. Home air conditioners are typically rated in tons, but different manufacturers may rely on one or the other, tons or BTUh to rate their systems. A 1-ton rating is equal to a 12,000 BTUh rating. Ratings typically break at 0.5-ton points creating a 1.5, 2, 2.5, 3, and so on rating scale. Choosing the right system depends on the square footage of your home and the climate where you live. The larger your home, the higher capacity rating you will need.
While choosing a unit’s efficiency ratings is an important part of identifying the right air conditioner for you, there are many factors that play a role in determining ideal unit capacity. Among them, the square footage of your space and the climate zone you live in are the primary considerations.
Multiply your homes total square footage by 20 to determine the BTUh rating you will need to cool your entire home. Divide the BTUh number by 12,000 to get the proper ton rating.
While this basic calculation can give you a rough idea of the air conditioner size that’s right for your home, we strongly recommend against relying solely on a square footage calculation. There are many other factors that can affect the true BTUh rating of your home. We suggest scheduling a professional energy audit or dealer assessment to ensure you get the most from your HVAC purchase.
The information gathered in a professional energy audit will go a long way toward optimizing the efficiency of your system, maintaining year-round comfort for you and your family, and maximizing the lifespan of the system you choose.
A Manual J calculation, the standard BTUh assessment used across the industry, is the most precise measurement available for home HVAC capacity. In addition to square footage, the Manual J process takes a number of factors into account, such as:
- Climate zone
- Ductwork
- Number and style of windows
- Natural shade or sun exposure
- Quality and amount of insulation
- Number of people using the space
- Heat-generating appliances
Many utility companies offer Manual J audits and reports for free. If yours doesn’t, you can hire an HVAC dealer or energy auditor to perform your inspection.
