Benefits Of A Second Ac Unit
Installing a second AC unit in your RV can be a great investment. It offers numerous benefits that can make your travels more comfortable and enjoyable. Let’s explore some of these benefits.
Enhanced Comfort
A second AC unit can significantly enhance comfort in your RV. It ensures that the entire space remains cool, even on the hottest days. Without it, certain areas may feel much warmer than others. A cooler environment means better sleep and a more pleasant living space. Everyone in the RV can stay comfortable, no matter where they are.
Improved Air Circulation
Improved air circulation is another benefit of a second AC unit. It helps distribute cool air more evenly throughout the RV. This prevents hot spots and keeps the air fresh. Improved circulation can also help reduce humidity levels. Lower humidity means less chance of mold and mildew. This can contribute to a healthier living environment for you and your family.
Types Of Ac Units For Rvs
Choosing the right AC unit for your RV can greatly enhance your comfort. The type of AC unit you select depends on your specific needs and the size of your RV. Here are some common types of AC units for RVs.
Rooftop Units
Rooftop units are the most popular choice for RVs. They are installed on the roof and can cool the entire RV efficiently. These units save space inside your RV. Rooftop units often come with different BTU ratings, allowing you to choose based on your cooling needs. The installation cost can vary, but it is generally higher due to the complexity of the installation.
Portable Units
Portable units offer flexibility and are easy to install. They can be moved around the RV to cool specific areas as needed. These units are usually more affordable than rooftop units. They do not require permanent installation, which makes them a convenient choice for many RV owners. Portable units are ideal for smaller RVs or those who need a temporary cooling solution.
Factors Affecting Installation Cost
Installing a second AC unit in your RV can improve comfort during travels. However, the cost can vary based on several factors. Understanding these factors will help you budget better and make informed decisions. Below, we discuss the key elements that affect the installation cost.
Unit Size And Type
The size and type of the AC unit play a significant role in the overall cost. Larger units are generally more expensive than smaller ones. They also require more power and might need additional modifications to your RV. Additionally, the type of AC unit, whether it’s a rooftop, portable, or window unit, can influence the cost. Rooftop units are often more expensive to install due to their complexity and the need for roof modifications.
Labor Charges
Labor charges can vary greatly depending on the complexity of the installation. If your RV requires significant modifications, labor costs will be higher. The location and experience of the installer also affect labor charges. Hiring a skilled technician might cost more but ensures a proper and safe installation. Always get a detailed estimate before proceeding with the installation.
Diy Vs Professional Installation
Deciding whether to install a second AC unit in your RV yourself or hire a professional can be challenging. Both options have their pros and cons. Understanding these can help you make an informed decision.
Pros And Cons Of Diy
Installing an AC unit yourself can save money. You won’t pay for labor. DIY projects also give a sense of accomplishment. They let you learn new skills. Yet, DIY installation has its risks. Mistakes can be costly. You might damage the RV or the AC unit. Lack of experience can lead to poor installation. This can reduce the unit’s efficiency. It might also void the warranty.
Advantages Of Hiring A Professional
Professionals have the expertise to install AC units correctly. They ensure the unit works efficiently. This can extend its lifespan. They also follow safety standards. This reduces the risk of damage. Hiring a professional saves time. You avoid the hassle of doing it yourself. Professionals usually offer warranties on their work. If something goes wrong, you have support. This peace of mind is worth the cost for many RV owners.
Estimating The Total Cost
Installing a second AC unit in your RV can enhance comfort during hot seasons. Understanding the cost to install this unit involves multiple factors. This guide will help you estimate the total cost, ensuring you stay within budget.
Cost Of The Ac Unit
The first expense to consider is the cost of the AC unit itself. Prices vary based on brand, model, and features. Below is a table summarizing the average costs:
Brand | Average Price |
---|---|
Dometic | $600 – $1,000 |
Furrion | $500 – $900 |
Advent | $400 – $800 |
Consider energy efficiency and cooling capacity when choosing a unit. These factors can impact long-term operating costs.
Installation Fees
Installation fees can vary based on the complexity of the job and labor rates in your area. Typically, professional installation can cost between $200 and $500.
Factors affecting installation costs include:
- RV type and model
- Existing wiring and ductwork
- Additional parts or modifications needed
For a more accurate estimate, get quotes from multiple service providers. Ask about any potential additional charges to avoid surprises.

Tips To Save Money
Installing a second AC unit in your RV can be a significant investment. But, with some smart strategies, you can save money without compromising on quality. Here are some practical tips to help you reduce costs while ensuring your RV remains cool and comfortable.
Seasonal Discounts
Timing your purchase can lead to substantial savings. Many retailers offer discounts during off-peak seasons. Consider shopping for an AC unit during the fall or winter. During these times, demand for air conditioners is low, leading to price reductions.
Another tip is to watch for holiday sales. Events like Black Friday or Memorial Day often have great deals on appliances. By planning your purchase around these sales, you can save a significant amount.
Price Comparison
Before buying an AC unit, take time to compare prices from different sellers. Online shopping platforms make this process easier. Check multiple websites to find the best deal.
Don’t forget to include shipping costs in your comparison. Sometimes, a slightly higher price with free shipping can be cheaper overall. Also, read customer reviews to ensure you’re getting a reliable product.
Consider checking both online and physical stores. Local stores might offer price matching or in-store discounts that aren’t available online. By doing thorough research, you can find the best price for your new AC unit.
Maintenance And Longevity
Installing a second AC unit in your RV can make a big difference. It provides comfort during hot weather. But keeping the unit in good condition is key. Routine maintenance and care can extend its lifespan. This saves you from costly repairs. It also ensures your unit works efficiently.
Routine Maintenance
Regular check-ups are important. Clean or replace the air filters every few months. Dirty filters restrict airflow. This makes the unit work harder. Check the unit’s coils. Clean them if they have dirt buildup. Inspect the fins and straighten them if they are bent. This helps the unit cool more effectively.
Look for leaks in the system. Fix them immediately to avoid bigger issues. Check the fan motor and lubricate it if needed. Keep an eye on the thermostat. Make sure it works properly. These small tasks can make a big difference.
Extending The Lifespan
Proper use can extend your AC unit’s life. Avoid running it non-stop. Give it breaks to cool down. Use it in moderate settings. This prevents overheating. Keep the vents open and unblocked. This allows better airflow.
Consider using a surge protector. It protects the unit from power spikes. Store your RV in a shaded area. This reduces the load on the AC unit. Cover the unit during winter. This protects it from dust and debris. Simple steps like these can help your AC last longer.

Common Installation Mistakes
Installing a second air conditioning unit in your RV can make your travels more comfortable. But, there are some common mistakes that can lead to problems. Avoiding these mistakes will help ensure your new AC unit works well and lasts a long time.
Improper Sizing
Choosing the right size AC unit is crucial. An AC unit that’s too small won’t cool your RV efficiently. On the other hand, a unit that’s too large will cycle on and off too frequently. This can lead to increased wear and tear.
Here’s a quick guide to help you with sizing:
RV Size | Recommended AC Unit (BTUs) |
---|---|
Under 200 sq ft | 5,000-7,000 BTUs |
200-300 sq ft | 8,000-12,000 BTUs |
Over 300 sq ft | 13,000 BTUs or more |
Inadequate Sealing
Proper sealing is important. Poorly sealed units can lead to air leaks. This reduces the efficiency of your AC unit. It also increases energy consumption.
Follow these steps for proper sealing:
- Ensure the AC unit fits snugly in the installation space.
- Use weatherstripping to seal gaps around the unit.
- Apply a high-quality sealant around the edges.
- Check for leaks by feeling for air drafts.
By avoiding these common installation mistakes, you can ensure your second AC unit operates efficiently. This will keep your RV cool and comfortable during your travels.
