What to Look For When Buying a Mach 3 Plus RV AC
When you’re ready to invest in a new Mach 3 Plus RV air conditioner, keep these key factors in mind to ensure you make the best choice for your rig:
- BTU Capacity: Most Mach 3 Plus units offer 13,500 BTUs, which is suitable for many mid-sized to large RVs. Consider your RV’s square footage and insulation when assessing if this is enough.
- Airflow (CFM): A higher CFM (cubic feet per minute) means the unit can move more air, cooling your space faster. The 320 CFM offered by these units is generally excellent.
- Heat Element: Decide if you need an AC unit that also provides heat. Some Mach 3 Plus models include an electric heat element, offering year-round climate control.
- Shroud Material & Color: While mostly aesthetic, the color (white vs. black) can subtly affect how much heat your unit absorbs. Shroud material also speaks to durability.
- Construction Quality: Features like all-copper tubing and brazed joints indicate a more durable and long-lasting unit, reducing the chance of leaks and breakdowns.
- Profile (Medium/Low): A medium profile is common for Mach 3 Plus units. Consider roof clearance and overall aesthetics.
- “Signature Series” vs. Standard: Signature Series models often include enhanced features like improved coil design for better efficiency, so weigh if these upgrades are worth the investment for your RV comfort.
- Compatibility: Ensure the unit is compatible with your existing RV wiring and ducting (if applicable) or if you’re replacing an old Coleman-Mach unit, check for a direct fit.
Installation & Maintenance Tips for Your RV AC
Getting your RV air conditioner installed correctly is crucial for its performance. If you’re not comfortable with electrical work or heavy lifting, it’s always best to have a professional RV technician handle the installation. Once it’s in, here are a few simple maintenance tips to keep your Mach 3 Plus RV air conditioner running smoothly:
- Clean Filters Regularly: Your interior air filters can get dusty quickly. Check them monthly and clean or replace as needed to ensure optimal airflow and efficiency.
- Inspect the Shroud: Periodically check the exterior shroud for cracks or damage. A damaged shroud can expose internal components to the elements.
- Clear Debris: Keep the rooftop unit free of leaves, twigs, and other debris that can obstruct airflow or damage the coils.
- Consider a Cover: As seen with the BougeRV cover, using an RV AC cover during storage or off-season can significantly protect your unit from UV rays, harsh weather, and debris, extending its lifespan. Remember to remove it before use!
- Check Condenser Coils: If you’re handy, gently clean the condenser coils occasionally to remove dirt and grime, which can hinder heat dissipation.
