How to Choose the Right Air Conditioning System for Your Home: A Cool Guide from Sea to Shining Sea

How to Choose the Right Air Conditioning System for Your Home: A Cool Guide from Sea to Shining Sea

A Chilled Salute to the USA!

From the scorching summers of Arizona to the sultry heatwaves of Florida, from the shimmering plains of Kansas to the bustling cities of New York and California, homeowners and construction professionals across our beloved United States face the pressing need to combat our country’s varied temperatures. And what’s more American than ensuring our homes are as comfortable and welcoming as possible, whether we’re hosting a Fourth of July barbecue or retreating from the crowded celebrations of New Year’s Eve in Times Square? 

Welcome to our National Air Warehouse blog, a space we’ve carefully crafted with you in mind. Whether you’re a DIY enthusiast seeking to revamp your living space, a homeowner looking to cool down a sweltering summer, or a construction professional advising clients, we’re here to guide you through the ever-important process of selecting the right air conditioning (AC) system for your home. 


Understanding Your Cooling Needs: A Journey Across America

Just as the United States is known for its rich tapestry of diverse landscapes, climates, and experiences, so too are the cooling needs of its residents. From the beachfront homes along Florida’s iconic Space Coast to the historic estates nestled in Virginia’s Shenandoah Valley, selecting the right AC system isn’t a one-size-fits-all approach. 

To make an informed decision, you must first understand the cooling load of your home. This refers to the amount of heat energy that needs to be removed to maintain a comfortable temperature. Here’s how:

  1. Evaluate your geographical location: The average temperatures, humidity levels, and seasonal changes of your location will significantly impact your cooling needs. For instance, if you’re enjoying the sea breeze in Malibu, your AC system will face different demands compared to if you’re withstanding the dry heat of a Texas summer.
  2. Inspect your home’s layout and design: The size, orientation, and construction materials of your home will affect its heat absorption and retention capacities. Does your home have energy-efficient windows and insulation? Or do you live in a charming, albeit less efficient, colonial-style home in Boston’s Freedom Trail?
  3. Assess your personal comfort needs: Every family is unique. Some enjoy a crisp, cold home, while others prefer a mild coolness. Your ideal temperature range will dictate the cooling capacity required from your AC system.


Choosing the Right Air Conditioning System: Unveiling the Great American AC Tour 

Having assessed your cooling needs, you’re now ready to choose the perfect AC system for your home. There are four main types of residential AC systems:

  1. Central Air Conditioners: These are the most common systems in American homes, especially in large suburban houses like those found in the picturesque neighborhoods of Charleston, South Carolina. They cool air in a central location and distribute it throughout your home using ducts.
  2. Ductless Mini-Split Air Conditioners: Ideal for homes without ductwork, these systems are popular in urban dwellings like those iconic San Francisco Victorian homes. Each room has its own mini-split system, providing personalized comfort.
  3. Heat Pumps: A versatile choice, heat pumps provide both heating and cooling solutions. They’re a hit in areas with milder climates like the idyllic Napa Valley vineyards.
  4. Portable and Window Air Conditioners: Perfect for small spaces or temporary cooling needs. They’re the go-to choice for cooling down those quaint cabins in the Smoky Mountains or providing a breath of fresh air in a bustling Chicago apartment.


Factors to Consider when Choosing an AC System: Honoring the Pioneering Spirit of America

America is a land of pioneers, always moving forward and innovating. In that spirit, choosing the right air conditioning system also means considering several factors that cater to efficiency, sustainability, and the ever-evolving advancements in HVAC technology. 

  1. Energy Efficiency: Opt for systems with high SEER (Seasonal Energy Efficiency Ratio) ratings. Much like our pioneers, who had to make the most of their resources on the Oregon Trail, a high SEER rating ensures that your AC unit uses less energy for the same cooling output.
  2. Size of the Unit: The size of your AC unit should be proportionate to the size and layout of your home. Oversized or undersized systems, much like wearing a coat in the Florida Keys or a swimsuit in Alaska, can lead to inefficiency and discomfort.
  3. Installation and Maintenance: Consider the complexity of installation and the accessibility for regular maintenance. Just as the care is taken to preserve our cherished national parks, regular maintenance is essential to ensure your system runs optimally.
  4. Cost: Evaluate your budget and consider both upfront and long-term operating costs. It’s like planning a trip from the Statue of Liberty all the way to the Golden Gate Bridge—you need to plan for both the immediate expenses and those that will pop up along the way.

Conclusion: Embrace the Cool Comfort of Home, from Sea to Shining Sea

Choosing the right air conditioning system for your home is a significant decision, much like deciding which national monument to visit next. But with the right understanding of your cooling needs, knowledge of the different systems available, and consideration of crucial factors like energy efficiency, unit size, maintenance, and cost, you can confidently choose the system that will keep your home comfortable no matter the season.

Ductless Mini Split Sizing Guide

Ductless Mini Split Sizing Guide

Are you in the market for a mini-split heat pump? Before making a purchase, it’s essential to know how to size the system to ensure optimal performance and energy savings. A ductless mini-split system is an excellent way to heat and cool various areas of your home efficiently. The first step in choosing the right size mini-split for your home is to measure the specific dimensions of each room. With these measurements, you can determine the correct capacity needed to heat and cool each area effectively. It’s important to note that a system that is too small will struggle to heat or cool your space, while an oversized system will be inefficient and waste energy. Follow this mini split buying guide to help you choose the perfect size system for your home.

Why Proper Mini-Split Sizing is Important

Size matters when it comes to mini splits. Here are three reasons why:

  1. Comfort: An underpowered unit may not be enough for a room, while an oversized unit may struggle to maintain temperature and cycle on and off, causing wasted energy.
  2. Utility: An oversized unit can be inefficient in terms of initial and operating costs, space occupied, and power consumption. An undersized unit can lead to bigger bills as it needs to run for longer periods and on higher settings to cool the room.
  3. Short cycling: Oversized units can struggle to maintain the temperature in smaller spaces, resulting in more wear and wasted energy.

What Size Mini Split Do I Need?

A Guide to Choosing the Right Mini Split Size

If you’re looking for an energy-efficient way to cool your home, a ductless mini-split system can do the job. To ensure your mini-split can adequately cool your space, it’s crucial to choose the right size. First, determine the number of rooms you want to cool, and then calculate the square footage of those rooms. The capacity of the mini-split system is measured in BTUs, and the larger the space, the more BTUs are required. You can use a BTU-to-room sizing rule of thumb to estimate the mini-split BTUs per square foot needed for efficient cooling. Keep in mind that mini-splits can cool a larger area compared to portable air conditioners with the same BTU rating. Consider using a mini-split calculator to help you choose the appropriate size for your space.

To calculate the room size, follow these steps:

  • For square and rectangular spaces, multiply the length by the width.
  • For triangular spaces, multiply the length by the width, then divide by two.
  • For non-standard linear spaces, divide the room into squares, rectangles, or triangles as applicable, determine the size of each subplot, then add everything together.
  • For circular spaces, measure the diameter, divide it by two, square it, then multiply the result by π (3.14159265).

Other Factors to Consider

Aside from square-foot-to-BTU, several other factors can affect cooling performance, including:

  1. Heat load: The heat gained by the room from different sources such as insulation, windows, floors, ceiling, and location.
  2. Ceiling height: If higher than eight feet, increase your BTU total by the difference in height.
  3. Sunlight: If the room gets lots of suns, add 10%. Reduce the BTU by 10% if the room is heavily shaded.
  4. Room type: For kitchens, add 4,000 BTUs to compensate for heat emitted by appliances. For garages, consider the level of insulation and weather.
  5. Capacity: Add 600 BTUs for each additional person occupying the room regularly or for long periods.
  6. Insulation: Add 20% if the room is poorly insulated to compensate for heat loss.
  7. Location: Consider adding 30% BTUs if you live in the south or in climates that experience seasonal temperatures over 90 degrees Fahrenheit.

Indoor-to-Outdoor Unit Ratio

When installing a mini-split system, it’s important to consider the indoor-to-outdoor unit ratio. Multi-zone units allow you to connect several indoor units to one outdoor compressor. However, it’s important to ensure that the total load of the indoor units doesn’t exceed the outdoor unit’s capacity by more than 30%, depending on the model.

Proper sizing of a mini-split system is essential for optimal performance and energy-efficient cooling and heating of your home. Oversizing or under-sizing can result in reduced efficiency, higher energy bills, and premature wear and tear on the system. It’s important to consider factors such as the square footage of the space, insulation levels, and local climate, especially during heat waves when heat-related illnesses are a concern.

Using a mini-split calculator or consulting with a professional can help you determine the appropriate size and configuration for your mini-split system to ensure efficient and effective cooling and heating.

Casement Window Air Conditioners: A Guide

Casement Window Air Conditioners: A Guide

Casement windows offer a visually appealing option for homeowners, with better ventilation and natural light. However, standard rectangular air conditioning units may not be suitable for these windows. Luckily, there are casement window air conditioners available that are designed to fit perfectly. These air conditioners are specifically engineered to fit casement windows and provide effective cooling. The American Society of Heating, Refrigerating, and Air Conditioning Engineers recommends using properly sized and installed AC units to ensure efficient and comfortable cooling.


What are Casement Windows?

Casement windows are a great choice for well-ventilated rooms like kitchens and bathrooms. These windows open outwards through a crank handle, providing maximum airflow. They lack frames in the middle of the glass, offering an unobstructed view of the outside and letting in more light, similar to picture windows. Compared to sash windows, casement windows have stronger seals, making them more energy-efficient. To maximize the benefits of your casement windows, consider investing in a room-to-room Zoneaire portable air conditioner. These units are easy to install and do not obstruct the window, providing a cost-effective and space-saving solution for cooling your room.


What are Casement Window Air Conditioners?

When it comes to heating and cooling a single room, wall room air conditioners are a popular choice. These ACs, also called through-the-wall air conditioners, are installed directly into the wall, providing a more permanent heating and cooling solution than casement window air conditioners. Wall room air conditioners are designed to fit into a sleeve that is installed into the wall, with the AC unit then sliding into the sleeve. They are typically more energy-efficient than window units and can also provide better indoor air quality by filtering out pollutants and allergens. The size of the room is an important factor to consider when selecting a wall room air conditioner as they come in various sizes to accommodate different room sizes. For those looking for the best garage air conditioners, wall room air conditioners with heating capabilities are an effective option that can provide reliable heating and cooling throughout the year. Heating refrigerating and air (HVAC) professionals can provide advice on selecting the right unit for your garage or home.


Casement Window AC vs Other Window Air Conditioners

When it comes to cooling a room, homeowners have several options to choose from, including traditional window ACs, sliding window ACs, casement ACs, and mini splits. While traditional and sliding window ACs have a box-type body and are wider than they are tall, casement ACs are specifically designed to fit narrow, vertically-swinging casement windows. They are typically more expensive than traditional window ACs but offer a sleek and compact design that makes them ideal for narrow window openings.

Another option for cooling a room is mini splits, which do not require a hole in the wall as casement ACs do. Mini-splits consist of two units – an indoor unit and an outdoor unit – and are connected by a conduit. They are energy-efficient and easy to install, making them a popular choice for homeowners.

In summary, casement ACs are a great option for those with narrow, vertically-swinging windows who want a compact and efficient cooling solution. However, mini splits offer an even more energy-efficient and flexible alternative that does not require a hole in the wall. Ultimately, the best cooling solution depends on the homeowner’s specific needs and preferences.


Casement AC vs Portable AC

When considering options for cooling and heating a room, homeowners can choose between casement window air conditioners and portable units. Portable air conditioners are available in two types: vented and ventless. Vented portable air conditioners require an exhaust hose that must be directed outside through a window. On the other hand, ventless units are less efficient but do not need any windows for ventilation. The advantage of using portable air conditioners is that they do not obstruct the casement window and are more affordable and easier to install compared to window ACs. However, it is important to note that portable air conditioners with heat pumps are generally more energy-efficient and can save homeowners money in the long run, according to the Department of Energy. In summary, for those who want a cost-effective and space-saving option for air cooling and heating, a portable unit with a heat pump is worth considering.


How to Choose a Casement Window AC

When choosing a casement window AC, there are several things to consider:

  • Determine the window dimensions: All casement ACs are less than 15” wide. However, you need to take into account the crank window installation kit, which can add an extra inch to the total width. Manufacturers typically provide a minimum window width in the specs sheet. The industry standard is a 15 ½” minimum window width. Make sure the AC’s specified minimum window width and maximum window height fall within your casement window dimensions.
  • BTU sizing: The cooling capacity of all AC units is measured in BTU (British Thermal Unit). While standard window ACs can go up to 15,000 BTUs, casement window ACs have a typical upper capacity of 8,000 to 10,000 BTUs owing to their narrower design. Use a BTU calculator to determine the required capacity for your particular room.
  • EER: EER stands for Energy-Efficiency Ratio, which is a measure of energy efficiency derived by dividing the BTU by the wattage. The higher the EER, the more energy-efficient the unit is.

Looking for the best portable AC unit for your casement window?

Look no further than the Frigidaire FFRS0822SE 8000 BTU Slider/Casement Window Air Conditioner.

  • This portable air conditioner unit is specifically designed for slider and casement windows, with an 8,000 BTU cooling capacity and 10.8 EER. It can cool spaces up to 350 sq. ft., depending on ceiling height.
  • The FFRS0822SE comes with electronic digital controls for easy use, as well as a full-function remote control. It also has a 3-speed fan, sleep mode, and auto restart in case of a power failure.

SEER Rating Guide: Choosing the Right Efficiency Rating for Your AC

SEER Rating Guide: Choosing the Right Efficiency Rating for Your AC

SEER rating, or Seasonal Energy Efficiency Ratio, is a critical factor in determining an air conditioning system’s energy efficiency. To get the best value for your money, it’s essential to choose the appropriate SEER rating for your air conditioner. This guide will discuss SEER and whether a higher rating is worth the annual operating cost, the difference in efficiency between a 16 and 14 SEER system, and whether a high or low average cost per kWh is better. Additionally, we’ll examine the impact of SEER rating on your income statement, taking into account your operating hours and electricity rates per kWh.


Understanding SEER

SEER stands for Seasonal Energy Efficiency Ratio, and it measures the efficiency of a new air conditioning system by comparing the cooling output to the energy consumed during a typical cooling season. A higher SEER rating indicates better energy efficiency and may be required to meet efficiency standards in some areas.


What is a Good Seasonal Energy Efficiency Ratio for an Air Conditioner?

The minimum SEER rating for air conditioners produced in the US is 14, as set by the US Department of Energy. However, SEER ratings can go as high as 23 for some high-end models. So, how do you know what a good SEER rating is for your air conditioner?

The answer to this question depends on several factors, such as the climate in your area, the size of your home, and how often you use your air conditioner. Generally speaking, if you live in a warm climate and use your air conditioner frequently, a higher SEER rating is recommended. Conversely, if you live in a cooler climate or use your air conditioner infrequently, a lower SEER rating may be sufficient.


Is a Higher SEER Rating Worth It?

When selecting an air conditioning system, a high SEER rating can lead to better energy efficiency and ultimately lower energy bills. However, it can also mean a higher initial cost. To determine whether a higher SEER rating is worthwhile, consider your budget, annual cost, and energy consumption patterns. By evaluating these factors, you can find a system that strikes a balance between efficiency and affordability, ultimately providing long-term savings and greater comfort.


How Much More Efficient is a 16 SEER vs. a 14 SEER?

Upgrading to a 16 SEER air conditioning system can provide a significant improvement in energy efficiency, with approximately 14% greater efficiency than a 14 SEER system. However, it’s important to note that SEER ratings do not account for cooling capacity, which is also a crucial factor to consider when choosing an air conditioner. It’s essential to select an air conditioning system with a SEER rating that matches your cooling needs to ensure optimal energy efficiency and comfort in your home. Consider consulting with a professional HVAC technician to determine the best SEER rating and cooling capacity for your specific needs.


What SEER Rating Should I Buy?

When it comes to purchasing an air conditioner, the SEER rating is a crucial factor to consider. A higher SEER rating means better energy efficiency and lower operating costs. However, the SEER rating you choose should be based on your specific needs and circumstances. Factors such as your budget, energy consumption habits, and climate in your area all play a role in determining the ideal SEER rating for your air conditioner. By choosing an appropriate SEER rating, you can ensure that you’re getting the most efficient system for your needs while also keeping costs manageable.


Is It Better to Have a High or Low SEER?

When selecting an air conditioning system, keep in mind that a higher SEER rating can indicate better energy efficiency, but it can also result in a higher upfront cost. It’s crucial to take into account your budget and energy requirements, such as your annual kWh consumption and cost, to find the perfect balance. Additionally, consider choosing a split system, which separates the condenser and compressor from the indoor air handler. This can provide more flexibility and potentially better energy efficiency by allowing you to only cool the rooms you’re using at any given time.


SEER Rating Calculator

To determine the operating cost of an air conditioning system based on its SEER rating, you can use a SEER rating calculator. Here’s how the formula works:

Divide the cooling system’s rated BTUs by its stated SEER rating to determine how many watts it consumes per hour.

Multiply the result by the number of hours the system operates annually to determine the total number of watts consumed on an annual basis.

Divide the total number of watts by 1000 to convert it to kilowatt-hours, which is how energy usage is billed.

For example, let’s say you have a 3-ton air conditioning system with a SEER rating of 15. The formula would be as follows:

36,000 BTUs (3 tons) ÷ 15 SEER

8 Air Conditioning Tips for Tampa Bay Homeowners

national air warehouse air conditioning tips

Having a home that is cool and comfortable is most important for your health and comfort. And if you are living in an area where temperatures reach up to 100 degrees on average, it’s especially important to get the most out of your cooling system. Here are some tips to help you keep your AC system running and save you from HVAC repair.

Fans can lower your AC costs.

If you have a ceiling fan and your air conditioner is working well, then you can use the fan to circulate the cool air around the room. This will also help keep closed doors from getting hot by adding some airflow as people come and go throughout the day.

Installing a programmable thermostat

Installing a programmable thermostat is an easy way to save money on your electric bill. If you’re handy and comfortable with basic electrical work, you can install one yourself. If not, you can call in a professional or hire an electrician to do the job for you.

Setting your thermostats offer convenience because they let us program our home’s temperature from wherever we happen to be at any given moment—no more running around turning up heaters every time someone opens a door!

Keep your air filter clean.

Keeping your air-conditioning filter clean will not only help your unit run at peak performance, but it can also save you money in the long run. A dirty air filter can cause it to work harder and longer, potentially causing it to break down sooner.

A good rule of thumb is to check your filters monthly and change them every three months if they aren’t easy to clean or if they seem worn out (if the seams are ripping). If you’re unsure if it needs changing, inspect them for mold or mildew growth on the edges of filters that are difficult to reach with a vacuum cleaner attachment.

Get rid of dust on the AC coils.

You can use a vacuum cleaner to get rid of dust from the coils. Avoid using water to clean them, as this could cause damage to the motor and other components. Also avoid using a broom or brush, as these can scratch the coils and create more problems than they solve. If you must use an abrasive cleaner, be sure it is nonabrasive; otherwise, you might end up damaging your AC unit even more!

Make sure the air conditioner is not in direct sunlight.

Place your air conditioner in a shady area, out of direct sunlight and away from heat sources. Since heat can build up inside the unit causing damage, it is important to place it in a spot where it will not be affected by direct sunlight or near any heat source such as a radiator or fireplace.

Install insulation around all windows and doors that lead outside.

The second step to improving the efficiency of your heating and air conditioning system is insulating all doors and windows leading outside. This can be done by adding insulation to walls, ceilings, floors and attics. Insulating the walls will help keep heat inside the home during winter months while preventing it from seeping through in summertime. Insulating ceilings helps to better regulate temperature because hot air rises up (and cold air falls down).

Seal any air leaks in your home (and replace weatherstripping)

Replace weatherstripping or reposition it. While you can buy new weatherstripping, you can also reposition the existing weatherstripping. Look at where air is coming in and apply more material to seal that area better.Close window coverings when you’re not using them. This will help keep cool air out of your home during the winter months, as well as reduce drafts around windows and doors year-round.

Air Conditioning service should be at least once per year

If you live in a hot climate, we highly recommend that you have your air conditioning (indoor and outdoor unit) serviced at least once per year to make sure your system is running efficiently. A poorly maintained heating and cooling system can cost you money and put your home at risk for damage caused by the buildup of mold, mildew, and bacteria.
The tips above are just a few of the many ways you can use to keep your home cool and improve indoor air quality. Saving on energy costs is important, and these tips will help you do that without sacrificing comfort or convenience—and with minimal effort!

Important Facts About Your Air Conditioner And The Environment

Are you an air conditioner user?

Research shows  It’s easy to see why. Especially in the south, summer months without air conditioning can be uncomfortable and miserable. In spite of the fact that about ⅓ of houses below the poverty line use air conditioning, it’s not cheap. In the US, an estimated 29 billion dollars. That includes repairs and energy costs.

If you’re looking to cut down on your energy costs, a programmable thermostat is one way to save a lot of money throughout the year. You can set it to turn off when you’re not around, or put it on a timer at night and save yourself around $180 per year. lower CO2 emissions. For each degree above 72F, you’ll save 120 lbs of CO2.

Another thing to keep in mind about your air conditioner: Whatever you’re using, it’s important to keep it in proper repair at all times. A well-primed air conditioner is generally safe for the environment, except for the energy usage it takes to run it and the greenhouse gases it takes to produce it. But a damaged or leaky air condition carries a risk of pouring CFC or CFM into the atmosphere.

With only 42% of air conditioner owner’s calling a professional when a repair is needed, that’s a lot of greenhouse gases being poured into the air. And a lot of energy to run your HVAC system when it starts to get dusty or wear down. Make sure to get your central air unit cleaned regularly, and have your window box air conditioners checked out by a certified professional as soon as you notice leaking or any other kind of damage.


Another option is a portable AC unit. Smaller AC units run on battery power, which significantly reduces your energy output, and there are eco-friendly options that use greener sources of fuel. Since they’re made to be smaller, they’re great for campers, and tiny houses. It means you can take them with you wherever you go, even if it’s just to the next room. That saves energy, the environment, and your wallet!

These days, it’s more common to have an air conditioning unit than a dishwasher, or even a garage. It makes sense. With global warming heating the planet, keeping cool in the summertime becomes even tougher to keep cool. But with about 2 tons of carbon dioxide, it’s a complicated situation. The heat leads to the air conditioner, which increases greenhouse gas emissions, which is slowly cranking the heat up. Air conditioners are a fact of life, but there are steps you can take to keep costs and CO2 missions to a minimum

Your Guide to Choosing a Standalone TXV: Sizing, Types, and Costs


In an earlier post, we covered the basics of the Thermostatic Expansion Valve (TXV) — what it does (and does not do), plus some of the considerations you have to make when deciding whether or not to add a TXV to your purchase or purchase a standalone TXV for an existing system. With newer systems, you may not have to make that choice at all, since a TXV is often already incorporated for efficiency purposes. However, if it becomes clear that you need to add a standalone TXV to your system, it is important to make sure you choose the right product for your system. Read on for more information about the sizing, refrigerant types, and costs of purchasing a standalone TXV.

The Right Model for Your System

When buying a standalone TXV, you have to choose one that is consistent with the cooling capacity of your system. The cooling capacity is a measure of your air conditioning system’s ability to remove heat from the air in your home in a certain amount of time. The unit of measure for cooling capacity is tonnage. Typically, a TXV is designed to work for systems that fall within certain tonnage ranges. That means you can find:

  • A TXV for 1.5 to 2 ton systems
  • A TXV for 2 to 3 ton systems
  • A TXV for 3.5 to 5 ton systems

Refrigerant Type

You may have heard that the R22 refrigerant is being phased out in favor of the more environmentally friendly R410-A. However, many homeowners still have legacy air conditioning systems that utilize R22, so you can find a TXV that is compatible with either one of these refrigerant types. When you are choosing between products, make sure that the TXV you buy is optimized for the refrigerant that your system utilizes.

Cost Considerations

If you’re buying a standalone TXV for an existing system, you can expect to spend around $100, or a little less. When considering the cost of a TXV, you may also want to factor in the warranty, which can add value the product. At the same time, you should also recognize that field installation presents a possible cost — unless you’re a home-builder or a do-it-yourselfer, in which case installation may be less of a concern.

Currently, National Air Warehouse offers a Goodman TXV (of any size) for $91.69, with free shipping. This product also comes with a one-year warranty. Contact us today to learn more about this TXV and all of our other products!
