Complete Technical Specifications

Accurate specifications are essential for ensuring vehicle compatibility and power system planning. We provide detailed technical data to help fleet managers and dealers select the right 13,500 BTU replacement AC for their specific application. Review the data below to match your power configuration and cooling needs.

Cooling Capacity and Coverage Area

Our 13,500 BTU air conditioner is rated to cool approximately 300 to 400 square feet of insulated living space. This capacity effectively manages heat in standard travel trailers, medium-sized RVs, and large truck sleeper cabs. For vehicles over 28 feet long or with poor insulation, we recommend installing two AC units or upgrading to a 15000 btu rv air conditioner.

Voltage Options (110V / 220V / 12V / 24V DC)

We offer multiple power configurations to meet the needs of global markets and different vehicle types.

• 220V / 110V air conditioner Models:
  Standard for RVs and campers when using shore power or a generator.

• 12V/24V DC Models:
  Ideal for truck sleeper cab air conditioners and off-grid vans, running directly from the battery bank without needing an inverter. This efficient DC air conditioner design is perfect for heavy-duty commercial fleets.

Operating Power and Startup Surge

Understanding power consumption is crucial for sizing generators and solar systems. A standard 115V 13.5K rooftop air conditioner typically requires 1250 to 1500 watts of running power. However, the compressor needs a momentary “surge” of power to start, which can peak between 2800 and 3000 watts. We offer optional soft-start capacitors to reduce this surge, making it possible to run on smaller generators.

Current Draw and Generator Requirements

In a standard 115V system, the unit draws approximately 11 to 13 amps of current during normal cooling operation. We recommend having at least a 3000-watt generator so the AC can run comfortably alongside other onboard appliances. For 12V RV air conditioner models, the current draw is higher (typically 40 to 60 amps), requiring a powerful alternator and battery bank.

Unit Size, Weight, and Roof Thickness Compatibility

Our low-profile RV air conditioner is designed to minimize wind resistance and clearance issues.

• Weight: Approximately 75-90 lbs (34-41 kg), ensuring it doesn’t overload the vehicle’s roof structure.

• Roof Thickness: Adjustable mounting bolts make it compatible with standard roof thicknesses from 1.5 inches to 5.5 inches.

Technical Data Sheet

Compatibility and Installation Guide

Proper fit is the most important factor when upgrading a mobile AC system. Our 13,500 BTU replacement air conditioner is designed for universal compatibility. Whether you are a manufacturer installing new units or a dealer doing retrofits, our design ensures seamless integration.

Ducted vs. Non-Ducted System Options

Our units support both air delivery methods to match your vehicle’s design.

• 13,500 BTU Ducted Air Conditioner:
  This model connects directly to your RV or bus’s existing roof ductwork. It distributes cold air through ceiling vents, efficiently cooling multiple rooms.

• 13,500 BTU Non-Ducted Air Conditioner:
  Ideal for pop-up campers and truck cabs, this type uses a ceiling assembly (air distribution box) to blow air directly from the unit into the main living space.

• Note:
  The rooftop unit is often the same; the interior ceiling assembly determines whether it is ducted or non-ducted.

Retrofit and Upgrade Compatibility

This AC system is an ideal replacement (13,500 BTU) for old or damaged RV air conditioners. It uses the industry-standard 14-inch x 14-inch (360 mm x 360 mm) roof opening. If you are replacing an AC from a major brand, our system will likely fit directly into the existing space. This “universal” design eliminates the need for expensive roof modifications or cutting.

Installation Steps Overview

Installing a new rooftop AC unit is straightforward.

1. Safety First: Disconnect all power sources (shore power and batteries).

2. Remove Old Unit: Remove the old ceiling assembly from inside, disconnect the wires, and lift the rooftop unit off.

3. Clean Surface: Clean the roof area around the opening to ensure a waterproof seal.

4. Install New Unit: Place the new 13.5K AC unit over the opening, ensuring the gasket aligns properly.

5. Secure and Wire: Bolt the unit down from inside using the ceiling assembly and connect the 110V or 12V power wires.

Required Tools and Estimated Time

Professional installation typically takes 60 to 90 minutes. Experienced DIYers can also complete the job with basic hand tools.

• Tools Needed: Phillips screwdriver, socket wrench set, putty knife for sealant, electrical tape/connectors.

• Team Lift: The rooftop unit weighs about 80 lbs; we recommend two people lift it safely onto the vehicle roof.

13,500 BTU vs. 15,000 BTU — Which One Should You Choose?

Choosing the right size is critical for comfort and power management. Many buyers think “bigger is better,” but upgrading to a larger AC isn’t always smart. Here’s how our 13,500 BTU replacement AC compares to the larger 15,000 BTU model to help you guide your customers to the right choice.

Cooling Performance Comparison

The main difference is cooling capacity. A 13,500 BTU air conditioner is designed to effectively cool vehicles up to 25-28 feet long and maintain a comfortable temperature difference (ΔT) of 18-22°F from the outside air.

• 13.5K Unit:
  Great for medium-sized RVs, truck sleeper cabs, and bedroom units in large fifth-wheel trailers.

• 15K Unit:
  Better for large Class A RVs or vehicles operating in extreme desert heat (above 100°F).

Power Consumption Differences

Power supply is the biggest deciding factor.

• 30-Amp Limit: If your vehicle uses a 30-amp power supply, a 13.5K BTU air conditioner is the safer choice. It draws about 12-13 amps, leaving roughly 17 amps available for other appliances like a microwave or water heater.

• Breaker Tripping: A 15,000 BTU unit can draw 15-16 amps. On a 30-amp connection, running a 15,000 BTU AC and a microwave at the same time could easily trip the main breaker.

Climate-Based Recommendation Guide

An AC that’s too powerful can actually reduce comfort. If the AC is too powerful (for example, installing a 15,000 BTU unit in a small camper), it will cool the air too quickly and cycle off frequently (“short cycling”) before it can remove humidity.

• Choose 13,500 BTU:
  Good for humid climates or smaller spaces. It runs longer cycles, effectively removing moisture from the air, making the space feel drier and more comfortable.

• Choose 15,000 BTU:
  Only for very large spaces or dry, extremely hot environments where maximum cooling capacity is the only priority.

How many square feet will a 13,500 BTU air conditioner cool?

A 13,500 BTU air conditioner will typically cool 300 to 400 square feet of insulated space. In a mobile setting like an RV or camper, this cooling range is ideal for vehicles up to 26 to 28 feet long. Factors like window tinting, insulation (R-value), and exterior color can affect the actual cooling range.

Is a 13,500 BTU air conditioner good?

Yes, it is the industry standard. A 13,500 BTU air conditioner unit offers the best balance between cooling performance and energy efficiency. It effectively cools most medium-sized RVs without overloading the standard 30-amp electrical system, making it the most versatile and popular replacement choice.

Will a 3000-watt generator run a 13,500 BTU air conditioner?

Yes, a 3000-watt generator is generally sufficient to run a 13.5K rooftop air conditioner. However, you must carefully manage other appliances. If the AC compressor starts while a microwave or hair dryer is running, it could overload the generator.

What size generator do I need for a 13,500 BTU air conditioner?

We recommend a generator with at least 3000 watts for reliable operation. If you plan to run other high-power appliances simultaneously, or if you are at high altitudes (where generator performance drops), a 3500-watt generator is recommended for a safer margin.

How many amps does a 13,500 BTU air conditioner draw?

On average, a 13,500 BTU air conditioner will draw 11 to 13 amps when the compressor is running (on 115V power). During startup, the current can briefly spike to 18-20 amps.

What size inverter do I need to run a 13,500 BTU air conditioner?

To run this unit on battery power, you need a powerful inverter system. We recommend a 3000-watt pure sine wave inverter. Modified sine wave inverters can damage the sensitive electronics in the AC unit or cause the motor to overheat.

Will a 3500-watt generator run a 13,500 BTU air conditioner?

Absolutely. A 3500-watt generator handles the startup surge of a 13,500 BTU air conditioner with ease. It also has plenty of reserve power to run lights, a TV, or a refrigerator at the same time.

How many watts to start a 13,500 BTU air conditioner?

Starting requires much more power than running. When the compressor starts, expect a momentary power draw of 2800 to 3000 watts. Installing a “soft start” capacitor kit can reduce this power requirement by up to 50%.
