Coleman Signature Mach 3 RV AC | 38263-069 | 13.5K BTU | Textured Black

Cool your RV reliably with the Coleman Mach Signature Mach 3 RV Air Conditioner (Part #38263-069) in textured black — the Signature-series variant of the popular 13,500 BTU Mach 3 platform. With 320 CFM of airflow matching the bigger Mach 15, R-32 next-generation refrigerant, and the same proven medium-profile design that fits any standard 14"×14" roof opening, this Signature Mach 3 delivers reliable cooling with a textured black shroud finish.

⭐ Textured Black Signature Finish

This Signature variant features a textured black shroud finish — a modern darker look that complements dark RV exterior color schemes with a non-polished textured surface.

Other Signature Mach 3 Finish Options

• Coleman Signature Mach 3 (38263-065) — Polished White
• Coleman Signature Mach 3 (38263-066) — Arctic White
• Coleman Signature Mach 3 (38263-068) — Polished Black

If you prefer the standard textured white shroud finish, see the Coleman Mach 3 Plus (38203-066) — Textured White. Same internal specs and performance across all — different shroud finishes.

13,500 BTU — The Preferred Mid-Range Choice

13,500 BTU of cooling — substantial output for most RV cooling scenarios:

• Mid-size to large travel trailers and fifth wheels
• Smaller motorhomes
• RVs in moderate to warm climates
• Setups with typical cooling loads (well-insulated, normal sun exposure, average size)

320 CFM Airflow — Matches the Mach 15

One of this platform's standout specs: 320 CFM of evaporator airflow — the same airflow rating as the much larger 15,000 BTU Mach 15. That airflow capacity makes this unit equally effective in both ducted AND non-ducted ceiling assemblies. Strong airflow pushes cool air through long ducted runs while still maintaining performance in non-ducted installations.

R-32 Next-Generation Refrigerant

Uses R-32 refrigerant — the next-generation low-GWP refrigerant that replaces R-410A in all new Coleman Mach production:

• Approximately 70% lower global warming potential than R-410A (GWP ~675 vs ~2,088)
• Zero ozone depletion potential
• Improved energy efficiency in many operating conditions vs R-410A
• Meets 2025 EPA AIM Act refrigerant requirements

The 38xxx prefix across all current Coleman Mach models indicates R-32 charge. Note: R-32 is classified as A2L (mildly flammable) — service must be performed by a qualified technician using appropriate equipment.

Built for Years on the Road

Shares Coleman Mach's engineering discipline across the lineup:

• All-copper tubing throughout the refrigerant circuit — no aluminum compromises
• Gas-flux brazed joints — higher integrity than standard soldering, resists vibration fatigue and thermal cycling stress
• Large evaporator and condenser coils with raised lance-style fins — maximizes heat transfer surface area
• Medium-profile shroud (13.8" tall) — lower aerodynamic drag than older standard-height units

Signature Mach 3 vs. Mach 15 — Which Should You Pick?

Same medium-profile platform, same 320 CFM airflow, same R-32 refrigerant, and same 14"×14" mounting standard as the Mach 15. The key difference: BTU capacity.

• Signature Mach 3 (13,500 BTU) — the right choice for mid-size to large RVs with typical cooling loads in moderate to warm climates; draws 13.1 amps
• Coleman Mach 15 (15,000 BTU + Heat Pump) — the right choice for large motorhomes, long fifth wheels, heavy cooling loads, or extreme heat climates; year-round comfort with integrated heat pump

For most RV owners not regularly camping in extreme summer heat, the Mach 3 is more than adequate cooling. The Mach 15's additional 1,500 BTU advantage matters most when sustained pull-down in high ambient temperatures or large/poorly-insulated spaces is needed.

Optional Heat Strip

For shoulder-season comfort without firing up the furnace, a compatible resistance heater assembly (sold separately) drops into the Signature Mach 3 to add electric heat capability. The unit itself is cool-only.

⚠️ Ceiling Assembly & Thermostat Sold Separately

The 38263-069 is the upper (rooftop) unit only. A complete installation requires:

• A compatible ceiling assembly — ducted or non-ducted (sold separately)
• A compatible thermostat / wall control (sold separately)

The unit ships with a pre-installed roof compression gasket on the base — no additional roof sealant required for the rooftop unit itself. Professional installation recommended given the unit weight, electrical connections, and need for a secure leak-free roof mount.
