What Size AC Unit Do I Need for My Home in South Florida?

Congratulations! You’ve made the decision to have a new air conditioning unit installed in your South Florida home. Now the real decision-making process begins, as you need to choose the brand and type of unit, as well as the size. The other two decisions are important, but less crucial than the size, because you need to ensure that the AC unit you select is powerful enough to keep your entire home cool. Wondering what your options are and where to start? Here’s what you need to know in order to make this crucial “cool” decision.

Factors to Consider When Choosing an AC Unit for South Florida Homes

When selecting an AC unit for your South Florida home, it’s essential to understand that a variety of factors can influence your choice beyond square footage alone. These considerations ensure that the unit you pick will be efficient, cost-effective, and powerful enough to handle the Florida heat. Here are some additional factors to keep in mind:

• Insulation Quality: Proper insulation helps keep cool air inside and prevents heat from creeping into your home. If your home has high-quality insulation, you may be able to opt for a slightly smaller AC unit and still maintain comfortable temperatures.
• Home Layout: A single-story home and a multi-story home with the same square footage will likely require different cooling strategies. Multi-level homes may benefit from separate zoning or multiple smaller units for customized cooling control.
• Energy Efficiency Ratings: Look for air conditioners with high SEER (Seasonal Energy Efficiency Ratio) ratings, as they can save on energy costs and reduce your home’s carbon footprint over time.

What Size Do I Need in South Florida?

Before you call up your local AC service in South Florida, you first need to educate yourself about air conditioners in general. This will help you understand what you’re looking for and why. It all starts with your climate zone. Although you might be familiar with the USDA climate zones that are used to determine which plants will grow in your area, as far as air conditioning is concerned, this zone is a bit different. The United States has been divided into five zones based on average temperature. Zone one is the hottest, and not surprisingly, this is where Florida lies. This means that you’ll need a stronger air conditioner in order to remain cool in the summer months. Someone living in one of the cooler zones, such as zone five, which abuts Canada, will need an AC unit that’s smaller and less powerful, due to their climate. Another term that you need to be familiar with is the Manual J Calculation. This number is dependent on many factors, ranging from the square footage of your home to the number of windows and doors that it has. The overall ceiling height is another factor to consider. All of these things will help you determine the HVAC load, or strength of the AC unit, that you need to keep your home cool. Your local HVAC service in Pompano Beach can help you with this.

Why AC Unit Size Matters More in Humid Climates Like Florida

South Florida’s climate is not only hot but also extremely humid. This combination requires an AC unit that can handle high moisture levels effectively. If your AC unit is too small, it will struggle to cool and dehumidify the space, causing it to run constantly without achieving desired results. On the other hand, an oversized unit may cool the room too quickly, leading to inadequate dehumidification and a clammy feeling indoors. Choosing the right size ensures balanced cooling and moisture control, making your living space comfortable even on the most humid days.

How Many Tons of AC Do I Need Per Square Foot in Florida?

Given Florida’s intense climate, you’ll need an AC unit powerful enough to keep your home comfortably cool even during peak summer heat. In order to find one, there are some things that you can do, including:

• Know the Terms and General Sizing – When it comes to air conditioners, the HVAC team that you contact might as well be speaking another language. Thankfully, if you educate yourself on those terms, like the Manual J Calculation, the BTU calculation, and even the HVAC load, then you’ll understand what the consultant is talking about. This will help you make an educated decision.
• Ask Your Neighbors – If you live in an area filled with houses that are of a similar shape and size to yours, you can ask them how their AC systems are set up. They might have different zones, with different machines for each level, allowing them some customized control. They might also have units of a certain size, and you can ask how well they work to see if something similar will work for you.
• Contact the Experts – Of course, you can purchase and install a central AC unit in your home, but you’ll need an AC service in Pompano Beach for that. These experts can help you determine the right size air conditioner for your home, and even walk you through the different models and options. They’ll do everything from talk you through the process to installing the unit. One example is Natal Air Conditioning. We have over 30 years of experience in the South Florida area, and we’ll also beat any competitor’s new install price by 5%!

AC Size per Thousand Square Feet

Let’s break things down. If you have a home that’s a certain square footage, which size AC would you need?

How to Calculate Air Conditioner Size for a House?

There are two main ways to determine which AC size is needed. The Manual J Method, which we already went over, relies on numerous factors like:

• Square footage
• Insulation quality
• Number of windows and doors
• Ceiling height

There’s also a measurement called the BTU or British Thermal Unit. You’ll see the measurement listed on the air conditioners that you’re considering. In general, you’ll need many of the same measurements as you would for the Manual J Method, but calculating BTUs is a little simpler. Start with square footage of each room that will be cooled. This could be the entire square footage of a house, or one single room, depending on the type of AC unit that you’re choosing and where you want it to be located. Take that square footage and multiply it by 25. You’ll end up with a number that’s in the thousands. Now the fun begins. If your ceilings are more than eight feet high, add ten percent onto that number. Add another ten percent if the room is super sunny in the middle of the day, or subtract ten percent if it’s well shaded. If you plan on air conditioning your kitchen, you’ll need to add 4,000 BTUs. This will give you a number to aim for when selecting an air conditioner.

Why Consult an HVAC Professional for AC Sizing and Installation

While it’s possible to do research on your own, consulting with a trusted HVAC professional provides valuable insights that can help you avoid costly mistakes. Professionals can help:

• Conduct a Detailed Assessment: An experienced technician can calculate the specific cooling load for your home, factoring in insulation, window quality, and even landscaping.
• Recommend Energy-Saving Models: They can suggest AC units with high energy ratings that qualify for rebates or tax incentives, helping you save money upfront and in the long run.
• Provide Expert Installation: Proper installation is crucial for efficiency and longevity. A professional installation ensures that the system is configured correctly to maximize airflow and minimize wear and tear.

Should I Repair or Replace My Air Conditioner System?

There are few things worse than having to deal with a broken air conditioner in the South Florida heat. So, before the humidity and high temperatures get you, you’ll have to make a decision: to either repair or replace your AC unit. Which is the best option? How do you know when your AC system is beyond repair?

Before you call your local AC service in South Florida, here’s what you need to know.

Is It Better to Repair or Replace an AC Unit?

If your air conditioner has broken down and you’re trying to determine whether to replace or repair it, there are few things to keep in mind:

• How Old is the Air Conditioner? – Like every appliance, your AC unit has a lifespan that’s either longer or shorter than similar models based on how well it’s been maintained. If you have an air conditioner that’s more than ten years old, even if it was previously in good working condition, it might be time to replace it with a model that uses less energy, thus lowering your electricity bill while keeping your home cool. However, if your air conditioner is only a few years old, it might still be under warranty, making fixing it a better option.
• What’s Wrong with It? – Another factor to consider is the issue you’re experiencing with the AC unit. Typically, problems involve the compressor or other mechanical parts, which can be simple to replace. With that said, there could be larger issues, such as a leak somewhere in the system where you’re losing coolant, leading to a much more costly repair. If this is the case, then you’d be better off replacing the entire system.
• How Much will the Repairs Cost? – Generally, the cost of repairs is the main factor when it comes to choosing AC replacement versus repairs. If the price quoted to you is less than half of what a new unit would cost, then you can consider the repair option. On the other hand, if repairs cost almost as much as a new air conditioning unit, then you’re better off simply replacing the entire thing, especially if your current one is on the older side.

When Should You Repair or Replace Your Air Conditioner?

Of course, this question may come up in the middle of the summer months when you discover that your air conditioning system is much less effective than it’s been in the past. This, combined with high energy bills, may be a sign that your unit is in need of either replacement or repair, even more so if you discover that it’s no longer working on the hottest day of the summer.

In order to avoid this type of situation, it’s important to have an HVAC company come out during the off season to test your system and see if it needs routine maintenance. At this point, you might discover that it would be more effective to have a new air conditioner installed, and you’ll be able to do so while the weather is still relatively mild.

Is It Worth Fixing an AC Unit Older Than Ten Years Old?

Usually, the ten-year mark is the cutoff when it comes to deciding whether or not your AC unit should be replaced or repaired. Some say that air conditioners can run well for up to fifteen or twenty years, but there are many reasons why these are extreme examples.

Once your AC unit gets to the ten-year mark, its lifespan will begin to decline rapidly. It won’t be as effective as it once was, even with routine maintenance done yearly to keep it running. This means that it will have to work harder to keep your home cool, leading to higher energy bills.

Plus, older units weren’t built to the current Energy Star standards that newer ones are. Newer models will use less energy to run, making them both more efficient and less expensive as far as electricity is concerned.

So, the million-dollar question is: should you fix your air conditioning unit if it’s at the ten-year mark? It depends on your budget, the cost of the repairs, and whether or not you plan on staying in the home for the time being. If you plan on moving, then investing in a new HVAC unit may not be the best option. However, if you aren’t going anywhere and want to stay cool in the summer, then opt for that replacement.

Average Cost to Fix and Replace an AC Unit

One of the main questions that people are concerned with involves pricing. How much is it to replace your air conditioner? How much does it cost to repair it? The amounts of both of those options vary considerably.

For repairs, it depends on the overall parts that need to be replaced, as well as the labor involved in the repair. Some are done quickly with a small part that doesn’t cost much, while others fall on the other end of the spectrum. Keep in mind that any repairs that will cost more than half the price of a new unit typically mean that it would be easier to replace the entire thing.

As far as replacement costs are concerned, these vary as well. The size of your home, the overall power of the AC unit, the model chosen, and whether or not your current ventilation system is compatible with the new unit all need to be taken into consideration. This is something you’ll need to ask your local HVAC company at your consultation.

How To Lower Your AC Bill During the Summer Heat in South Florida?

Although there’s nothing quite like summertime in South Florida, you’ll need a place to beat the heat once in a while. Your home, complete with cold, refreshing air conditioning, can become that very space. However, there’s one thing to worry about when it comes to cooling off during this time of year: your electric bills. They tend to be on the higher side, even despite the fact that your AC unit is in good working condition. 

So, how can you deal with these rising temperatures and electric bills? Here are some pro tips to keep your AC bill at an affordable level. 

1 – Use Ceiling Fans

Did you know that you can adjust the position of the blades on your ceiling fans? With one simple switch from down to up, they’ll elevate the warm air in the room and keep it near the ceiling, allowing you to cool off appropriately. By installing a ceiling fan in every room, you’ll be able to raise the temperature of your HVAC system and take advantage of the natural air flow produced by the fans. This will lower your energy bills accordingly since you won’t need as much AC. 

2 – Turn the Temperature Up a Bit

What’s the difference between 70 degrees Fahrenheit and 67 degrees Fahrenheit? Quite a bit when it comes to your energy bills. The lower the temperature, the more your AC will run, causing it to utilize a lot of electricity. However, since a comfortable home can be obtained with a slightly higher temperature, in this example, 70 degrees, you’ll still be able to enjoy everything that your cooling AC has to offer while saving some money on your energy bills. It’s amazing what the difference between three degrees can mean when it comes to paying for electricity every single month. 

3 – Keep Your Curtains and Blinds Closed

When calculating the size of the air conditioner that you need for your home, you need to count your doors and windows. Even the best sealed ones will allow for some air to escape. Plus, windows that aren’t covered at all allow the sun in during the hottest parts of the day, making your sun-facing rooms feel as uncomfortable and warm as a greenhouse. In order to combat this, you’ll need to lower the temperature in your home, making your AC run more and therefore cost more to operate. Thankfully, you can keep the rooms cooler by closing your curtains and blinds in the summer, blocking that warm light from coming in. 

4 – Use Fans Whenever Possible

Although it sounds counterintuitive, because standard floor and desk fans use up electricity, they actually don’t use as much as a whole home air conditioner. If you want to lower your energy bills, then you’ll need some fans. By contributing to the overall air flow in your home, you’ll be able to keep the temperature a little higher, preventing those cringe-worthy electric bills. Plus, the air flow will make you feel better, especially if you have pets or allergies because the fans will take care of some of the fur and pollen in the air. 

5 – Choose a Programmable or Smart Thermostat

When it comes to thermostats, there are several options, two of which can save you money. A programmable thermostat allows you to set up the system to adjust to a certain temperature at a specific time. For example, you can have it set to warm up during the day when you’re at work, and then automatically lower it at 5 pm when you’re on your way home. This way, you’ll come home to a comfortable temperature. Smart thermostats are similar, but they use AI technology to determine what the best temperatures are for you based on the patterns that they pick up over time. 

6 – Have Your Air Conditioner Maintained

Maintenance is the key to not only having lower energy bills but also having an air conditioner that lasts longer. You should get your AC unit maintained by a certified HVAC company at least once a year, preferably before the warm season (aka – summer) starts. This way, they’ll catch any issues before they have a chance to get worse, thus keeping your AC in great working condition. Having it run efficiently is the key to not having to pay huge electric bills in the summertime. 

7 – Change Your Air Filters

Did you know that your AC unit has air filters on it? These are designed to filter the air before it’s moved through the vents throughout your home. If you have a lot of pets or have been doing some home renovations or maintenance, then your air filters are probably dirty and will need to be changed around once a month. However, if you don’t have pets or home renovations in progress, then every three to six months will do. Once your filters are clean, the air won’t be forced as hard through them, leading to an air conditioner that runs less. 

8 – Choose an Energy Star Appliance

Older appliances don’t have the Energy Star certification on them. This means that they aren’t set up to optimize energy usage and tend to use a lot of power in order to run. As a result, you’ll pay a premium for that cool indoor air all summer long. Thankfully, newer air conditioners are Energy Star compliant, so they use less energy even if they’re run every single day. If you truly want to save money on your energy bills, then upgrading your older AC unit to a newer Energy Star one is the best way to go.
