Understanding Your RV's Air Conditioning Needs

Before we jump into specifics, it's critical to have a grasp on what your RV needs. Size, power source, climate, and your travel habits all influence the type of air conditioning parts and accessories that will best suit your vehicle.

Larger RVs might need more robust cooling solutions, while those roaming in moderate climates may prioritize differently than tropical adventurers. When selecting parts, consider how they'll work with your specific model and whether they're designed to meet your personal comfort requirements.

Coleman and Dometic: Why Brand Matters

Coleman and Dometic are the titans of the RV air conditioning world. They are renowned for their reliability, efficiency, and array of compatible parts and accessories. When browsing for upgrades or replacements, sticking with a trusted brand means you're investing in quality and ensuring compatibility with your existing system.

Ceiling Assemblies: More Than Just Vent Covers

Your RV's interior comfort starts at the top—quite literally—with the ceiling assembly. This component is the cockpit of your AC unit, housing controls, vents, and filters. When shopping for aDometic or Coleman ceiling assembly, look for:

  • Compatibility with your specific AC model
  • Durability and ease of cleaning
  • Options for integrated air filters
  • User-friendly control panels, if it includes one

Keep an eye out forcracks, damage, or discoloration as signs that it might be time for a replacement. A well-maintained ceiling assembly not only ensures consistent airflow but also contributes to the overall aesthetic of your RV's interior.

Navigating the World of Soft Starts

Particularly if you frequent campsites with limited or unstable power supplies, you'll want to consider a soft start for your RV air conditioner.Soft starts gradually ramp up the electrical demand when the AC kicks in, rather than the sudden jolt of power typically required.

BothColeman and Dometic offer soft start kits that can help protect your RV's electrical system and potentially extend the life of your air conditioner. When choosing a soft start, make sure it's compatible with your unit's specs and take note of the ease of installation—some might require professional installation, while others could be more DIY-friendly.

Heat Strips: Bringing the Warmth When You Need It

Even in paradise, nights can get chilly, and you'll be grateful for a bit of heat without having to run a separate furnace.Dometic and Coleman heat strips add heating capability to your AC unit, efficiently keeping you cozy during colder weather.

When shopping for a heat strip, double-check that it fits your specific air conditioner model. Additionally, consider the wattage to ensure it provides enough heat for your space without overloading your RV's electrical system.

Filters: The Unsung Heroes

Air conditioner filters might not be the most glamorous part of your RV AC system, but they're arguably one of the most important.Regularly cleaning and replacing your Dometic or Coleman RV air conditioner filters can vastly improve air quality and prevent strain on the system by ensuring optimal airflow.

Check the size and type of filter required for your unit, and stock up—having extras on hand can come in handy, especially during extensive travel. Remember, a clean filter is a simple and effective way to enhance efficiency and prolong your RV AC's lifespan.

Thermostats: The Gatekeepers of Comfort

Your RV's air conditioner thermostat is the brain behind your temperature control, allowing for precise adjustments to your environment. If you're experiencing inconsistent climate control or notice your system struggling to maintain set temperatures, it might be time to inspect your thermostat.

ForDometic and Coleman thermostats, compatibility is key. Evaluate programmable vs. non-programmable options and consider features such as digital displays or remote controls for added convenience.

Pro Maintenance Tips

To get the most out of your RV air conditioner and its new parts and accessories, adopt a proactive approach to maintenance:

  • Inspect Regularly: Check all AC components before and after trips, especially if your RV has been idle for an extended period.
  • Clean Filters Often: At a minimum, clean your AC filters every 90 days, or more frequently in dusty environments.
  • Test Your Thermostat: Before hitting the road, ensure your thermostat settings yield the desired temperatures.
  • Install Soft Starts Early: Adding a soft start kit before peak season can help manage the stress on your RV's electrical system during high-demand periods.
  • Monitor Your Ceiling Assembly: Periodically inspect for damage or blockages that could impede airflow.
  • Be Heat-Smart: Use your heat strip judiciously, relying on it for supplemental heat rather than as your primary heat source in freezing conditions.

By following these tips and keeping up with regular maintenance checks, you'll be far less likely to face unexpected issues during your travels.


Upgrading and maintaining your RV air conditioner parts and accessories is essential to ensure a comfortable and relaxing atmosphere in your home on wheels. By focusing on quality products from Dometic and Coleman, keeping a diligent maintenance schedule, and understanding the specific needs of your vehicle, you can sit back, relax, and enjoy your adventures no matter the temperature outside.

As you embark on your next journey, remember that your RV air conditioner is more than a luxury—it's a tool that, when properly cared for, can elevate your traveling experience beyond measure.
