The Ultimate Buying Guide: Soft Starts for Your RV AC
Does your RV’s air conditioner make a loud “thump” when it starts? Does it cause your lights to dim? If so, you need a soft start for your RV AC. A soft start is a small device that makes your AC unit start up more gently. This guide will help you choose the best soft start for your needs.
What are the Key Features to Look For?
When you shop for a soft start, keep these important features in mind:
- Compatibility: Make sure the soft start works with your specific RV AC unit. Check the wattage and amperage requirements. Some soft starts are universal, while others are made for certain brands or models.
- Ease of Installation: Look for a soft start that is easy to wire. Many are designed for DIY installation, but some might need professional help.
- Protection Features: Some soft starts offer extra protection for your AC unit. These can include surge protection or overload protection.
- Durability: RVs are often on the move. Choose a soft start that is built to last and can handle vibrations.
Important Materials
Soft starts are usually made with high-quality electronic components.
- Capacitors: These are key parts that store energy. Good quality capacitors help the soft start work smoothly.
- Circuit Boards: The internal circuit board should be well-made and protected from moisture and dust.
Factors That Improve or Reduce Quality
Several things can make a soft start better or worse.
- Improved Quality:
- Reputable Brands: Buying from well-known brands often means better quality and customer support.
- Good Reviews: Read what other RV owners say about the soft start. Positive reviews are a good sign.
- Warranty: A good warranty shows the manufacturer stands behind their product.
- Reduced Quality:
- Cheap Materials: Very cheap soft starts might use lower-quality parts that don’t last as long.
- Poor Wiring Instructions: If the instructions are hard to understand, it can lead to installation mistakes.
- Lack of Protection: A soft start without surge protection might not protect your AC from electrical spikes.
User Experience and Use Cases
Most RV owners install a soft start to improve their experience.
- Quieter Starts: The biggest benefit is the much quieter start-up. No more sudden jolts or loud noises.
- Reduced Power Draw: Soft starts help your AC use less power when it first turns on. This is great for your RV’s electrical system, especially when running on a generator or shore power with limited amps.
- Extended AC Life: By reducing the stress on the AC’s motor during start-up, a soft start can help your air conditioner last longer.
- Use Cases:
- Boondocking: If you camp without hookups and rely on a generator, a soft start lets your generator start the AC more easily.
- Campgrounds with Limited Power: Many campgrounds have 30-amp service. A soft start helps prevent tripping the breaker when the AC kicks on.
- Protecting Electronics: Dimming lights or other electronics acting strangely when the AC starts will be a thing of the past.
