Why A/C Unit For RV Trailer is Necessary?

I have been traveling in my RV trailer for years now and one thing I can’t imagine living without is the A/C unit. It has become an essential part of my travels and here’s why.

Firstly, the summer heat can be unbearable at times, especially when you’re on the road with no shade or shelter. Having an A/C unit in my RV trailer allows me to escape the scorching heat and cool down in a comfortable environment. It makes my journey more enjoyable and less exhausting.

Moreover, RV trailers are usually compact spaces and can get stuffy quickly, especially if there are multiple people inside. The A/C unit not only cools down the temperature but also helps circulate fresh air, making it a more pleasant living space. This is particularly important for those who have respiratory issues or allergies.

Another reason why an A/C unit is necessary for an RV trailer is that it allows me to travel to different destinations without worrying about the weather conditions. Whether it’s a hot desert or a humid beach town, I know that I will have a cool and comfortable place to retreat to at the end of the day.

My Buying Guide on ‘A/C Unit For RV Trailer’

As someone who loves to travel and spend time in my RV trailer, having a reliable and efficient air conditioning unit is essential. After going through the process of choosing and purchasing an A/C unit for my RV trailer, I have compiled a buying guide to help others make an informed decision.

1. Determine Your RV’s Power Capacity

The first step in buying an A/C unit for your RV trailer is to determine your power capacity. Most A/C units require a 120-volt outlet with at least 15 amps of power. However, some larger units may require more power or even a separate generator. It is important to know your RV’s power capacity before making a purchase.

2. Consider the Size and BTU

The size of your RV and the climate you will be traveling in will play a significant role in determining the size of the A/C unit you need. BTU (British Thermal Units) is used to measure the cooling capacity of an A/C unit. The larger your RV or the hotter the climate, the higher BTU you will need. Generally, for small to medium-sized RV trailers, an A/C unit with 13,500 BTU should suffice.

3. Choose Between Rooftop or Portable A/C Unit

There are two types of A/C units designed specifically for RV trailers – rooftop and portable units. Rooftop units are permanently installed on top of your RV trailer and take up less space inside compared to portable units that sit on the floor. On the other hand, portable units offer more flexibility as they can be moved around and used in different areas such as tents or cabins.

4. Look for Energy Efficiency

Since an A/C unit can consume a significant amount of power, opt for one that is energy efficient to save on electricity costs while traveling. Look for models with Energy Star certification or high EER (Energy Efficiency Ratio) ratings.

5. Noise Level

As someone who values peace and quiet while camping, I made it a point to choose an A/C unit with minimal noise levels. Some models come with noise-dampening technology or adjustable fan speeds that allow you to control the noise level according to your preference.

6. Additional Features

Some additional features that you may want to consider when buying an A/C unit for your RV trailer include remote control operation, digital temperature display, built-in air purifier or dehumidifier, and programmable timers.

7. Read Reviews and Compare Prices

Before making a final decision, read reviews from other users who have purchased the same model you are considering. This will give you insights into its performance and any potential issues that may arise. Additionally, compare prices from different retailers or online stores to ensure you get the best deal.

In conclusion, choosing an A/C unit for your RV trailer requires careful consideration of factors such as power capacity, size/BTU needs, type of unit, energy efficiency, noise level, additional features as well as reading reviews and comparing prices. With this buying guide in mind, I am confident that you will be able to find the perfect A/C unit for your RV trailer that will keep you cool during all your travels!
