Why Air Conditioner For Sliding Patio Door Is Necessary
From my experience, having an air conditioner specifically designed for a sliding patio door makes a huge difference in keeping my living space comfortable. Sliding doors often let in a lot of heat during the summer, and without proper cooling, the room can become unbearably warm. An AC unit fitted for the sliding door seals that gap perfectly, preventing hot air from sneaking in and maintaining a consistent temperature inside.
I also found that using a regular window AC or relying solely on central air conditioning wasn’t enough. The sliding door is a large glass surface that absorbs and radiates heat, so having an air conditioner tailored to that space helps reduce energy costs by cooling only the area that needs it most. Plus, it’s convenient because it doesn’t block the entire door, allowing me to still enjoy the natural light and easy access to my patio.
Overall, investing in an air conditioner for my sliding patio door improved my home’s comfort and energy efficiency. It’s a smart solution for anyone looking to stay cool without compromising on style or functionality.
My Buying Guides on ‘Air Conditioner For Sliding Patio Door’
When I decided to get an air conditioner for my sliding patio door, I quickly realized it’s a bit different from standard window units. After some research and trial, I want to share what I’ve learned to help you find the perfect fit for your space.
1. Measuring Your Sliding Patio Door
The very first thing I did was measure the height and width of my sliding patio door opening. Unlike typical windows, sliding doors are taller and wider, so it’s crucial to know your exact dimensions. This ensures you pick an air conditioner that fits well without leaving gaps for hot air to sneak in.
2. Choosing the Right Type of Air Conditioner
There are a few types to consider:
- Through-the-Wall Units: These require a permanent installation and a wall sleeve but offer a clean look and good efficiency.
- Sliding Door Air Conditioner Kits: These come with adjustable panels that fit into the door track, making installation easier and less permanent.
- Portable Air Conditioners with Sliding Door Kits: If you prefer flexibility, some portable units have kits to vent through sliding doors.
I personally went with a sliding door air conditioner kit because I didn’t want to modify my wall or door permanently.
3. Cooling Capacity (BTUs)
I learned that the cooling power, measured in BTUs, should match the room size. For a standard living area connected to the patio door, 8,000 to 12,000 BTUs usually work well. A unit too small won’t cool effectively, while too large a unit wastes energy and causes temperature swings.
4. Installation Ease
I looked for units that came with clear instructions and all necessary hardware. Some sliding door ACs have adjustable panels that slide into the door frame, making it simple to install and remove seasonally. I avoided models that required cutting or permanent changes to my door.
5. Energy Efficiency
Energy efficiency was a big factor for me since I wanted to keep electricity bills manageable. I checked for ENERGY STAR rated units and looked at the EER (Energy Efficiency Ratio). The higher the EER, the more efficient the unit.
6. Noise Levels
Since the AC would be in my living space, noise mattered. I read reviews and found units with noise levels under 60 decibels to be comfortable for daily use without disturbing conversations or TV watching.
7. Additional Features
I also considered some handy extras:
- Remote control for convenience
- Programmable timers to save energy
- Multiple fan speeds for customized comfort
- Dehumidifier function, which is great for humid climates
8. Price and Warranty
Finally, I set a budget and compared models within that range. I made sure to check the warranty terms—longer warranties gave me peace of mind in case of defects or issues.
Summary
Buying an air conditioner for a sliding patio door is a bit unique, but by measuring carefully, choosing the right type and size, prioritizing efficiency and ease of installation, and considering noise and extra features, I found a unit that keeps my space cool and comfortable all summer long. I hope my guide helps you do the same!
