Things to Consider

As we mentioned earlier on, there are so many different air conditioning units out there—a ton more than just the ones highlighted on our list.

So, to help you choose the best, we’ve created this guide to help you work through your buying decision.

As the heat goes up, your price of the best air conditioner shouldn’t have to. These appliances can be an inexpensive and energy-efficient alternative to keeping you cool, even during the hottest days.

Benefits of an ac unit at home

If you’re still on the fence about investing and installing an air conditioner in your home, we want to introduce you to a few benefits that come along with keeping it cool during the summer months.

Especially if you live in a hot state like Florida, you really shouldn’t give air conditioning installment a second thought—this type of investment should really be a no-brainer.

If the heat isn’t persuasive enough, here are some more benefits of having AC in your home (or workplace):

It can be a major benefit to your health—in so many different ways. Whether you’re worried about ousting bugs, insects, and parasites in your home or you’re preoccupied with breathing quality for your family, an AC unit can help get rid of those pesky creatures as well as provide fresh air to help reduce the possibility of asthma attacks.

Instead of paying for a gym membership, installing AC in your home can give you a cool environment (literally) to work out in. Instead of trying to beat the heat in the great outdoors, an indoor workout with AC can not only help you stay comfortable while exercising, but it will also make the process that much more pleasant.

It helps improve sleep. Falling under the category of being a health benefit, getting a good night’s sleep can lead to several other health improvements. Sleeping in a cooler environment can help increase the quality of your sleep, which can do wonders for you in general.

If you have an at-home office, it can help improve your work performance and prevent electronics from dangerously overheating. Getting work done can already be hard with all the distractions from family to household chores (or even entertainment options with more fun things to do with your time)—so, why make it harder on yourself? Installing AC in your home can help keep the comfort to a maximum and your productivity, as well. 

How does an air conditioner work?

Think learning about how an AC works is way too complicated for you? To help break the process down into simpler, easy-to-follow steps, we would advise you to watch the following video:

Know your air conditioner brand

When it comes to most products that have a longer warranty and can affect the health of your family, paying a bit more of a premium for a higher-quality brand can benefit you more than it can hurt you financially.

To help ensure that you’re getting premium product, we would definitely suggest going with the quality brands listed here, like the Friedrich Chill Series EP08G11B or the well-known Frigidaire FFRH1822R2.

Features to consider while buying the best air conditioner

Having the right air conditioning unit, however, is just as important as installing one in the first place. To help you find the proper size, type, and other details, this guide should be thorough enough to breeze you through the process.

Choose the type you need

One of the first steps in the buying (and choosing) process of finding an adequate air conditioning unit for not only your budget but also your home (or workplace) is going to be figuring out the type of air conditioning unit you need.

Although you might have heard of quite a few options out there on the market, two of the most common options of air conditioners are going to be portable and window—less popular types are also through-the-wall and built-in air conditioners.

If you simply need air condition in one direction, window air conditioners work best! There are also other options that do a great job of having the air on a swivel to help circulate it throughout the room.

You’re also going to have to make the educated decision to choose from various air conditioning systems, from ductless mini-split systems to central air systems.

Consider the room space

To help you choose, you need to consider the room and home space to best define what kind of type you need.

Depending on the size of your room or area—whether it’s as small as 100 square feet to as large as 1,000 square feet, you’ll need to choose a unit that has as little as 5,000 BTUs (which can help you save spending money on unnecessary power) like the Arctic King WWK05CM91N or has as many as 20,000 BTUs and up, like the Koldfront WAC25001W, which has 25,000 BTUs.

The location of the room, as well as the size, is also extremely important—which will dictate how many BTUs you need.

For example, if your room or area is sitting in the sunlight, you’ll need to have an increase of BTUs for your desired unit—like the 25,000 BTU-powered Koldfront WAC25001W.


The last thing you would want after you’ve invested time, research, and money into the installment of an air conditioning unit is to have one that simply makes a ruckus (even if you have a cool environment now to sleep in—the sound can possibly keep you up).

Generally, the generation of noise typically comes from the type or number of fans. If you need help choosing an air conditioning unit based on the noise level, check out the reviews and comments on the product (do a bit of research) to help see which brands and models keep it quiet—even if set on high.


The ability to control the temperature—as well as additional other features that can provide an overall beneficial experience—are also important to see before you buy.

Some models, like the SereneLife SLPAC8, come with additional features that can not only give you optimal control but also keep it comfortable in the comfort of your own home.

Some additional controls, like the one featured with this unit, include a built-in dehumidifier, digital touch button control panel, remote control, 24-hour timer, and a very generous seven feet in power cord length.

What is CEER?

You might have heard of this term before. Although you might know that it’s a good thing, you might not be exactly crystal clear on what it means—we’re here to help.

The “CEER”, the “Combined Energy Efficiency Ratio”, is a set standard that has recently upgraded the air conditioning market that has been officially stated by the Department of Energy.

The CEER is important when it comes to energy efficiency, measuring the energy it takes the air conditioning unit to use while it’s on as well as while it’s on standby.

The units featured on this guide go all the way up to 22.5.

Unit size

As we already mentioned previously on our guide, the issued size of the air conditioner can play a major role in how efficient it will be when working in your home or space. It can also have a direct impact on how well it actually even fits into your home.

Installation easiness

After you’ve done all that research, investment in time, and in money, the last thing you would also want is to have a difficult time with installation.

If you’re not planning on hiring a professional to install the air conditioner for you, you need to be aware that the various styles, types, and sizes of units will come with a different type of installation process.

Most units—especially when sold from the manufacturer will come with an instruction manual to help ease the process. However, if needed, you can also look up how-to videos to have a more visual learning tool.


Making the investment of cool air in your home goes a long way—hopefully.

Taking the warranty or guarantee into account can also play a huge role in the buying process. When ordering directly from the manufacturer, you’ll 100 percent have access to a guarantee or warranty for the unit.

Most of the units on this guide will come backed by a minimum of one year to as long as five years, like with the Friedrich Chill Series EP08G11B.

Cleaning easiness

Maintaining your unit has a crucial impact on the lifetime of your unit—no matter what the warranty says. There’s no use of having a longer warranty if you’re not keeping up with maintenance.

It’s advised to regularly clean and maintain your unit based on the manufacturer’s advice to help keep it in working order and pristine condition.


Depending on your budget, you will still have pristine air conditioner units available to you in your price range.

Even our most budget-friendly options still have the features that you would find in the most premium of choices, which makes the appliances quite accessible to the everyday user.


If you’re investing in an appliance like this one, you’ll definitely want one that can withstand time as well as use. Let’s face it—especially during those summer months, you’re going to be using it excessively!

If you have a question about the durability of your air conditioner appliance that you may think can only be answered with time, take a closer look at the manufacturer and if they’ve done a “durability test”. Most will have that labeled on their site that they’ve done long-term tests. These experiments are done normally under stronger and more straining conditions which will never be the case in a normal situation.

There are three major durability tests. They are:

  • The Continuous Operation Test
  • The Compressor Reliability Test
  • The Waterproofing Test

Cleaning tips

Although cleaning might not be your favorite thing in the world—yes, there are some people out there who love it—this task and responsibility can help with the maintenance of your air conditioning unit and getting the best years of it as possible.

Depending on the type of unit you have, the cleaning process may change quite a bit.

Central Air Unit

You need to make sure the power is completely turned off.

After doing so, you can begin with the air conditioner condenser using a vacuum and soft bristle.

Your AC Unit interior is next—which can also be cleaned with the vacuum hose.

Finally, remove and replace the air filter. Once all is thoroughly cleaned, you can then put all the parts back in and turn the power back on.

Again, make sure the power is completely turned off.

Front plate removal goes first—followed then by a thorough vacuuming near the coils.

You should then check the drain pan—which is located at the base of the unit. You might need to clean or replace them depending on the rust or blockage.

Next (and finally), check the filter to see if it needs to either be cleaned or replaced.


Before you buy—and definitely before you think about installing an air conditioning unit, you should make sure you read the answers to these most frequently asked questions.

You either might have had these questions before or you never knew you needed them answered before you read them!

How to install air conditioning units?

Although we definitely suggest consulting an expert when it comes to installing a central air conditioner, here are a few tips to help you out with the process.

You’ll first need to check out if your local government actually needs you to have a permit because of HVAC work. This can be done through a contractor but can also be done on your own.

Once approved (if it was required), you’ll then have the contractor or installer take the old air conditioner apart and remove it (if you have one).

Once the old is out of the way, new duct systems need to be installed or older ones need to be repaired to ensure optimal function.

Before installation begins, you need to prepare the area in which you’re going to be installing the unit. Refer to the manufacturer’s instructions on whether or not you’ll need a concrete pad or rooftop supports. This might be different depending on each air conditioning unit.

You also should check with a professional about whether or not you need to install or replace your outdoor AND an indoor unit. Once this is done, you should connect both units. This will involve the refrigerant and electrical lines as well as the drain piping.

Once everything is done, connect a new or existing thermostat to your unit.

How long ac units last?

After everything is installed and ready, you might be curious as to how long a unit will last. Although each unit is different, most units will generally last up to 15 years. However, if maintenance is not cared for regularly, this can be drastically reduced.

How do I find the CEER rating on my AC unit?

As we explained earlier on this guide, the CEER is a “combined energy efficiency ratio”, which helps dictate how efficient the energy is of your unit.

This number will be found located on the outside of your appliance. You can also look your particular unit’s model up on the AHRI website.

How does an HVAC system work?

To have your air conditioning unit work as effectively as possible, you should try and inform yourself about how it works—even to the most intricate of parts.

If you’re wondering about the HVAC system, which stands for heating, ventilation, and air conditioning, which are all functions of an air conditioner unit. This combination of systems helps you control various indoor settings to help regulate the environment and temperature to give you the best comfort possible.

The four different parts of the unit work together—from the air conditioner cooling the air found outside the home or area to the ventilation system, which replaces and exchanges the air within a space. It is a sort of purifier, which of air indoors and involves the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gases.
