For every challenge, there is a solution. While traditional air conditioning in a house or office building may help cool the majority of a large space, there are certain problem areas that need additional solutions. This could be a window that faces westward or an upstairs bedroom that collects lots of heat. Often, those problem spots can make the whole rest of the house system work overtime. This is increased costs and maintenance issues.

As energy costs increase during the summer months, and as concerns about climate change grow, wouldn’t it be nice to have something to help offset running your inefficient air conditioning all day and night just to cool one area?

To be more energy efficient, a well-placed mini window air conditioner will do the trick. It can work on cooling that one room or spot. This will stop it from taxing the rest of the system.

There are many expensive, window units out there. These have digital displays, remote controls, timers, and programming.While these can be useful for more permanent solutions, sometimes a good old-fashioned manual window unit is the right tool for the job. In this article, you’ll find everything you need to know about the Frigidaire Window-Mounted Unit in order to determine if it is the best window AC unit for you.

Frigidaire FFRA0511R1 5,000 BTU Small Window Air Conditioner

Frigidaire FFRA0511R1 Small Window Air Conditioner

  • 5,000 BTUs
  • 41 pounds weight
  • Room Size: 150 square feet
  • 2-year limited warranty

Product Information

This unit is a 5,000 BTU mini-compact air conditioner for window-mounted installation. It is small and lightweight, at only 41 pounds, which makes for easy installation. Installation kit is not included, however, and expert installation is available for an additional cost.

Given the BTU capacity of the unit, it is suitable for cooling up to 150 square feet of space. Other similar models are available with higher BTU capacities for use in larger spaces.

This model offers 2 cooling speeds and 2 fan speeds, while the models with higher BTUs offer 3 of each. It also has 2-way air directional control. The unit is very affordable, at under $200 and with free shipping. However, the buyer might need to pay for installation by an HVAC certified technician, which is an additional $100 at checkout.

It comes with a limited 2-year warranty, with an additional 3-5 year warranty on the sealed system, which includes the compressor, condenser, evaporator, and tubing.

This air conditioner is equipped with mechanical controls, meaning that all temperature adjustments are done via dials located on the unit itself. No remote control is available.

Easy to Use

This mini window air conditioner has a low power start-up with an effortless restart operation. The controls are mechanical rotary controls for both the cooling speed and the speed of the fans on fan mode. This gives you more reliable, custom controls at your fingertips without worrying about a digital display not working.

The dehumidifier removes 1.1 pints per hour and drains all the excess water outside. This helps to remove not only condensation but also excess moisture and humidity from a room. The luxury of having cool, dry air blowing on you in a summer’s heat is not to be missed.

Small and Flexible

This unit is small enough and the window kit is flexible enough that it should fit most windows. Be sure to check the specifications first before you buy. With the compressor outside of the window, noise is reduced, and all exhaust stays outside, so no unnecessary hoses are needed.

A common concern with window units is that you are blowing outside air directly into your room. To give you peace of mind, the Frigidaire uses antibacterial mesh filters with slide-out access. The filters are easily cleanable with a simple kitchen faucet and replaceable quickly afterward.

The accessories that come with the kit allow for easy installation. At just 41 pounds, it is easy to lift and install. With an extra-long cord, you do not need to worry about being too close to a power source. You do need a 115-volt electrical outlet, which should not be an issue for most locations. The automatic restart allows the unit to restore previous settings when power returns after a blackout or power outage.
