Buying Guide for Air Conditioner Units for Crank Out Windows
Understanding Crank Out Windows
When I first considered getting an air conditioner for my crank out windows, I realized that these types of windows open outward by turning a crank. This design can limit my options when it comes to air conditioning units, so I needed to do some research. I found that it’s essential to choose a unit that can securely fit and operate effectively with this style of window.
Types of Air Conditioners
I discovered there are a few types of air conditioners I could consider. Window units are the most common, but I also explored portable air conditioners. However, since I specifically needed a unit for crank out windows, I focused on window units designed for easier installation in this type of opening. I wanted something that would not only cool my space but also fit my window style perfectly.
Measuring My Window
Before making any decisions, I measured my window to ensure a proper fit. I measured the width and height of the window opening, accounting for any obstructions. This step was crucial because I learned that units can vary significantly in size. Getting the dimensions right helped me narrow down my choices significantly.
Cooling Capacity
I also needed to consider the cooling capacity of the air conditioner, measured in BTUs (British Thermal Units). I found that for my room size, the BTU rating needed to be adequate to cool the space efficiently. I researched how to calculate the appropriate BTUs based on my room size and the number of windows, which helped me select the right unit for my needs.
Energy Efficiency
Energy efficiency became a vital consideration for me. I wanted an air conditioner that wouldn’t lead to exorbitant electricity bills. I looked for units with high Energy Efficiency Ratios (EER) or those that are ENERGY STAR certified. This gave me peace of mind knowing that I was making a choice that would save me money in the long run.
Installation Considerations
I learned that installation could be a bit tricky with crank out windows. I looked into various installation kits that cater specifically to these types of windows. Some units come with adjustable panels that can help fit the air conditioner securely. I wanted to ensure that it could be installed safely without compromising the window’s function.
Noise Levels
Noise level was another factor on my list. I personally prefer a quieter environment, especially during the night. I read through customer reviews and product specifications to find units that operate at lower decibels. This helped me find an air conditioner that would keep my space comfortable without being disruptive.
Additional Features
As I browsed through options, I considered additional features that might enhance my experience. Features like remote control, programmable timers, and multiple cooling settings caught my attention. These conveniences would make it easier for me to adjust the temperature as needed.
Budgeting for My Purchase
Finally, I set a budget for my purchase. I wanted to find a unit that offered the best value for my money. While I was willing to invest in quality, I also made sure to compare features and prices across different brands to ensure I was making a sound financial decision.
Final Thoughts
After thorough research and consideration of all these factors, I felt more equipped to choose the right air conditioner for my crank out windows. The right unit can make a significant difference in my comfort during the hot months. Taking the time to understand my needs and the options available ensured that I would make a well-informed decision.
