• 2 – 120 VAC A/C (no heat pump)
• 0 – Standard (no solar, no condensate pump)
• 4 – 15,000 BTU
• A – Internal revision code
• 8 – Compressor vendor (Tecumseh)
• 7 – PTCR/Capacitor start kit
• 6 – White textured shroud

• Prefix (first 3–5 digits)

🔢 Coleman-Mach Model Number Breakdown

Each digit or character in the model number represents a specific attribute of the unit:

 

 

🧠 Example: Decoding

•              → R-410A refrigerant

•              → Standard profile Mach series

•              → 120V A/C

•              → Aftermarket, no solar or condensate pump

•              → 15,000 BTU

•              → Internal revision

•              → Tecumseh compressor

•              → PTCR/Capacitor

•              → White textured shroud

This unit is a 15K BTU, standard profile, 120V A/C with a Tecumseh compressor and white textured finish, designed for aftermarket installation.

 

📍 Where to Find Model Numbers

•             Rooftop Unit: Under the shroud, typically on the driver’s side or near the evaporator/fan motor

•             Ceiling Assembly: Behind the plastic grille, on the metal framework

Coleman-Mach Model Number Breakdown

Each digit or character in the model number represents a specific attribute of the unit:

Digit/Character	Meaning	Options / Notes
1st Digit	Refrigerant Type	4 = R-410A (current standard) 3= R-32 (eco-friendly, high-efficiency alternative to R-410A)
2nd Digit	Series/Profile Type	5 = Mach 10 (Low Profile) 7 = Mach 8 (Ultra Low Profile) 8 = Mach (Standard Profile) 9 = Polar Series
3rd Digit	Function & Voltage	0–1 = Heat Pump 2–3 = A/C 120V = Even numbers 240V = Odd numbers
4th Digit	OEM vs Aftermarket	0–3 = Aftermarket 5–8 = OEM (RV Manufacturer)
5th Digit	BTU Rating	0–1 = 8K 2–3 = 11K 4–5 = 15K
6th Character	Revision Code	A, B, C, etc. (internal design changes)
7th Digit	Compressor Vendor	8 = Tecumseh 6 = GMCC 9 = Rechi 7 = Boyard
8th Digit	Start Kit / Capacitor	6 = None 7 = PTCR/Capacitor 8 = Relay/Capacitor 9 = Soft Start Kit
9th Digit	Shroud Color/Finish	5 = White Polished 6 = White Textured 7 = Black Polished 8 = Black Textured
10th Digit	Misc Features	2 = Standard Top Mount 3 = Non-Ducted Quiet (NDQ) 4 = Ducted Quiet (DQ) 5 = RoughNeck 6 = MarineMach
