Frigidaire FFRA0511R1 – Specifications

While this is a pretty powerful unit, it costs about average to operate, and we wouldn’t recommend that it be used for rooms or spaces much larger than the manufacturers’ recommended 150 square feet. There is a window kit included with the air conditioner.

Frigidaire FFRA0511R1 – Efficiency

The Energy Efficiency Ratio of the Frigidaire FFRA0511R1 means that this unit will not win awards for efficiency, as it’s below the industry average of 11.24. Airflow may not on the face of it be the most powerful, but it will be perfectly fine in a room of 150 square feet. While this unit is well accredited in terms of its safety standards, the lack of Energy Star certification for many will tell its own tale.

Frigidaire FFRA0511R1 – Convenience

As a window air conditioner in 2018, the Frigidaire FFRA0511R1 is about as no-frills as they come. It will do its job, but without the benefits of remote controls, timers, sleep or energy-saver modes. It does have auto-restart, however, which is a handy setting if you live in an area that’s prone to outages, and you want your air conditioner to resume at your pre-sets.

Best Window Air Conditioner Review – Frigidaire FFRA0511R1 – Our Verdict

We liked the Frigidaire FFRA0511R1. It’s a strong machine for a small apartment or small to medium sized bedroom. However, don’t look to this machine if you’re looking for ‘bells and whistles’ in the form of energy saving or automatic features that will enable a fine degree of customization that accords to your daily schedule.

Frigidaire FFRA0511R1 - Our Verdict
This is quite basic but it really gets the fundamentals right. It's pretty efficient, easy to install, and dehumidifies at a rate of just over 1 pint per hour.
Frigidaire FFRA0511R1 - ProsFrigidaire FFRA0511R1 - Cons
Strong on the fundamentals, easy to install, and has a window-mounting kit included.Pretty basic on the little touches, such as remote control, auto and sleep mode and other fine detail features.

 

 

2. Best Window Air Conditioner Review – hOmeLabs 5000 BTU Window Air Conditioner

IMAGE SOURCE: AMAZON

This hOmeLabs AC unit is great for quick cooling of small spaces (up to 150 square metres), and its quiet operation makes it perfect for living and resting places such as bedrooms and small living rooms. A compact AC unit, measuring 16in wide x 15.4in high (12in deep), it offers seven speed settings, and can cool the temperature in a hot room within 10 minutes. Numerous window air conditioner reviews praise the unit’s user-friendliness and efficiency.

hOmeLabs 5000 BTU – Efficiency

While this has an average EER of 11.1, and it’s also welcome that it is Energy Star certified, what is less favourable from an efficiency point of view is the lack of information on its safety standard certifications. However, with seven cooling speeds and two fan speed settings, it’s difficult to quibble with a unit that will significantly cool down a 150 square feet room in less than 10 minutes.

The user will also be able to move the top slats approximately 40-degrees left or right and control the direction of the air flow from the top vent.

Best Window Air Conditioner Review – hOmeLabs 5000 BTU – Our Verdict

Like the Frigidaire product above, this is a very basic unit, but it will certainly do the job for a small living space such as a small apartment, bedroom or RV. It is very basic, however, and lacks the extra features that make other units so popular.

hOmeLabs 5000 BTU - Our Verdict
Your view on whether this constitutes good value for money will depend on how much you value features over cooling power, and if you're prepared for the fact that this is best suited for a small space only.
hOmeLabs 5000 BTU - ProshOmeLabs 5000 BTU - Cons
Pretty efficient and fast cooling performance, and great customer support makes this a winner for a 150 square feet space.Lacks the features that would make for a customizable, automated cooling schedule that can be tailored to your daily movements.

 

 

3. Best Window Air Conditioner Review – Frigidaire FFRA1222R1 12000 BTU 115V

IMAGE SOURCE: AMAZON

This compact air conditioner for window-mounted installation (mounting kit included), with standard 115V electrical outlet can quickly cool rooms of up to 550 square feet, with dehumidification of up to 3.8 pints per hour. The unit has an Energy Efficiency Ratio (EER) of 1.9, while its multi-speed controls, 24-hr timer and remote control make it a user-friendly winner, with features such as auto cool, energy saver mode, sleep mode, fresh air vent, exhaust control, 8-way air direction and washable mesh filter with ‘check filter’ alert.

This has a below-average EER of just 10.9, however, its powerful 12000 BTU will be more useful for medium to larger sized spaces. It’s also a pretty effective dehumidifier, stripping some 3.8 pints of moisture from the atmosphere every hour. While the lack of Energy Star certification is a bit disappointing, especially given the three fan speeds, we have to be more positive about a unit that has a suite of safety credentials.

This is a bit of a mystifying category in that on the face of it the Frigidaire FFRA1222R1 seems to tick every box of features that should make for a more energy efficient cooling and dehumidifying experience, and yet as we have seen already, it fails to run in an efficient manner. However, it does have sufficient features to make this if not energy-efficient, certainly much more convenient to operate than many smaller less powerful units.

And not only is there a handy tilt-out filter feature for easy cleaning access, but also an indicator to alert you when the washable anti-bacterial mesh filter needs to be cleaned. There is also an extra long cord (6.5ft) enabling easy placement.

Best Window Air Conditioner Review – Frigidaire FFRA1222R1 – Our Verdict

With no fewer than five operational modes and three fan and cooling speeds, this Frigidaire is a feature-rich unit at its price point. The energy efficiency rating is quite low, and the lack of Energy Star certification and the quite high estimated annual operating cost is a bit of disincentive if you’re planning on running this unit for long periods of time.

Frigidaire FFRA1222R1 - Our Verdict
What seems promising at first glance ultimately proves a bit disappointing in terms of energy-efficiency.
Frigidaire FFRA1222R1 - ProsFrigidaire FFRA1222R1 - Cons
Reliable brand, robust construction, rich in features with a high degree of customization to your daily schedule.Not the most energy-efficient machine of all the air conditioners reviewed for this post.

Best Window Air Conditioner Review – Koldfront WAC10002WCO 10,000 BTU Window AC – Our Verdict

This is a very efficient air conditioner for the space it’s recommended to be used in. It’s powerful and will cool down your space quickly and without fuss. There is good customer service available, although the warranty cover is not quite as generous as that provided by some of the other manufacturers here.

Koldfront WAC10002WCO - Our Verdict
One of the more energy efficient units that we reviewed for this post, the Koldfront WAC10002WCO is a fine performer, but might not work quite so well if your desired room size is much larger or smaller than the recommended 450 square metres.
Koldfront WAC10002WCO - ProsKoldfront WAC10002WCO - Cons
This is rich in features, very easy to use and easily be customised to your daily routine so that you have a comfortably cool living environment when you most need it.It's simply not as efficient as you'd expect if you apply it to spaces larger or smaller than the recommended 450 square metres. Also, the warranty cover is not as generous as some manufacturers provide.

While this will be an obvious attraction, from the LG brand, together with the data on energy efficiency and safety, some will be put off by its limited warranty cover, and the operational noise might be a little loud for some tastes too.

This is quite a decent air conditioning unit for medium sized spaces. It's energy-efficient and easy to use, but the limited warranty cover might be a disincentive to some prospective customers.

Haier ESAQ406P Serenity Series – Help & Support

Although the Haier website is the gateway to a fairly comprehensive range of after-sales supports, the one-year warranty to cover the compressor will be a crushing disappointment to many prospective customers.

Best Window Air Conditioner Review – Buyers Guide

This guide to the best window air conditioners aims to help you identify what to look for in a unit, determined by your own circumstances (in particular, room size), and enable you to conveniently create a cool, comfortable space during hot summer months.

No one likes hot, humid air. It’s very tiring to live and work in, and while there are always solutions available such as a quick swim or even vacationing in cooler climes, these options are not available to everyone. However, the best window air conditioner units are a pretty cost-effective solution to such a quandary.

They can be easily installed and don’t require major renovations or even much in the way of superficial upheaval within the home. You may not even have to move furniture to make way for them. All of these units are energy efficient, and while some are more energy efficient than others, they will all help cool down your desired space without costing you a fortune.

Small window air conditioners are very effective at cooling a room. You may be tempted to stick with your portable appliances, which to be fair, work very well and require no installation at all. However, they are simply not as efficient as a window AC unit.

 

 

Best Window Air Conditioner Review – How We Evaluated The Units

In our evaluation of the best window air conditioner units, we paid particular attention to the cooling ability and energy efficiency. They have to be able to maintain a comfortable temperature of your choosing. If it can’t do this, it’s not doing it’s job. We also considered factors such as how well the machine can distribute cool air, and how many different modes it has (i.e., fan only, dehumidifier only, etc).

We also considered each unit’s energy efficiency rating (EER) and attempted to estimate how much it will cost to operate the machines over a year. We considered user-friendliness, as manifest through convenience of operation, remote controls, programmable timers, and other features.

The units’ designs were also considered, in terms of heaviness and ease of installation. And noise was another hugely important factor that we considered when evaluating just how effective these machines are.

 

 

Best Window Air Conditioner Review – Factors to Consider

Here are the primary factors you need to consider when you are looking for a new window air conditioner.

 

Cooling Capabilities

The most important thing to look for in the best window air conditioners is how well a unit cools. We looked at each unit and considered the size of room it should be used in. It is important to note that a big, bulky machine may not be the right choice for you. Always know your room size and purchase accordingly. The Btu or British thermal units is a measure that will tell you the room size a unit suits best – this is something all our reviews have noted. Simply put you don’t want a unit that is too big or too small for your home.

It is also important to be aware of how much air will be coming out of your unit and how powerful that airflow is. You can find this out by taking note of your machines max airflow which is indicated by the cfm or cubic ft per minute which all devices tell you.

 

Energy Costs & Certifications

Be aware of how much a product’s annual running costs. Where possible, we’ve attempted to do this on the basis of a usage period of eight hours a day for three months, an industry-standard formula. Also, the EER of a product is important—the higher the EER, the more efficient the unit. The average EER is 11.24 – anything below this and you will start to see your annual energy bill rising.

Certifications should also be considered. Energy Star, UL listings and AHAM certs are all things we looked for in our reviews. Products that are Energy Star rated are 20-30% more efficient than what’s legally required. UL Listing means it has been tested by the independent body Underwriters Laboratories. AHAM deals with the Association of Home Appliance and Manufacturing, which certifies the build quality of your machine according to industry standards.

 

Portability & Design

You will want to know how easy the best window air conditioners units are to move, install and how long they will last in your room. You don’t need a burdensome unit to install so keep an eye out for weight and how well they will sit in your space. An average weight we have identified is about 60 pounds as a guide.

You don’t want any leaking air and you want to know that your window air conditioner will includes some kind of window kit that seals any open spaces. These kits tend to identify the weak point in these systems, as improper installation allows cool air to escape the room and hot air to enter the house.

 

Operation Modes

No matter what unit you decide to go for you will want to know what extra operation modes are offered by your product. This will allow you to determine how a window air conditioner will work for you depending on your needs. Look out for things such as fan only modes, extra cooling modes etc. An adjustable fan speed will allow you to maximise the cooling comfort of your room.

Those of us that live in humid spaces will know how important it can be to remove that excess moisture from the air. Therefore, you should be on the lookout for a dehumidify mode on your unit. This element is contained in most window units and saves you the hassle of having to purchase a dehumidifier separately.

Always be on the lookout for a sleep mode as this can really be of use during the night to give you a comfortable night’s sleep without allowing your room to get too cool.

 

Our Verdict & Recommendations

We think that all of these machines will work well as cooling machines, but of course, it’s a case of different strokes for different folks. It all depends on circumstances, and hopefully this guide will enable you to make correct decision for you.

  1. You can’t go wrong with the Frigidaire FFRA0511R1, and it’s right that you have it at Number 1. It’s fast and effective. A brilliant AC unit.

  2. Koldfront 10,000 BTU 115V is the one which I recommend. This is the one which I bought recently and it is working smoothly, also the maintenance cost is less.

  3. Wow, it’s interesting that you have provided us these best window air conditioner reviews. I’ve been searching this kind of information all along as we’re planning to install another 2 air conditioning units.
