2. Best Budget (Under $1,000): Coleman-Mach 48203-069 MACH 3 Plus

Coleman-Mach 48203-069 Signature Series MACH 3 Plus Medium-Profile Air Conditioner, 13,500 BTU, Textured Black

• Cooling: 13,500 nominal BTU
• Airflow: 320 CFM
• Coils: large evaporator and condenser coils with raised lance fins
• Shroud: textured black, medium profile

Check Price on Amazon

Why it made the list: No credible 13,500 BTU rooftop unit sells under $700, so we raised this award to Under $1,000. It sits within a few dollars of our overall pick, but it is the lowest-priced credible 13.5K unit and a natural swap for older Coleman owners. It holds 4.1 stars across about 50 ratings.

Highlights:

• Stated 320 CFM airflow
• Large coils for heat transfer
• Textured black shroud

Trade-off:

• Listing does not say which ceiling assembly or controls are included, so confirm before ordering

Best for: Owners replacing a Coleman rooftop unit who want the same brand and footprint.

3. Best Premium / Upgrade Pick: Dometic Penguin II Low Profile, 13.5K

Dometic Penguin II High Efficiency Low Profile Rooftop Air Conditioner, 13.5K BTU, Polar White, Cool Only

• Cooling: 13,500 BTU, cool only; 115V

• Housing: EPP foam shroud, rib-reinforced base pan
• Controls: works with Dometic CCC2 or CT thermostats, single or multi-zone (sold separately)

Check Price on Amazon

Why it made the list: The Penguin II is Dometic's low-profile rooftop unit, and the listing says its shape cuts wind resistance while its EPP foam housing keeps weight down. It works in ducted or non-ducted setups and ties into Dometic's multi-zone thermostats, which matters in larger coaches. It holds 4.0 stars across about 140 ratings.

Highlights:

• Low profile for less drag and roof height
• Ducted or non-ducted use
• Multi-zone thermostat support

Trade-off:

• No controls included; you need a compatible thermostat and ceiling hardware

Best for: Motorhome and fifth wheel owners with Dometic thermostats or ducted ceilings.

This guide is researched and compared; we did not test these units. We kept only 13,500 BTU rooftop units sold new on Amazon and left out models the maker no longer lists. We compared voltage and size, build and safety details, installation needs, features and warranty and value. Specs come from Amazon listings, and rating averages and counts showed how each unit is received.

Size & form factor

• 13500 btu: The standard rooftop size for most trailers and smaller fifth wheels.
• 15000 btu: More cooling for larger or sunnier rigs, with higher power draw.
• Low profile: Shorter shrouds like the Penguin II reduce height and drag.
• Ducted: Sends air through ceiling ducts to several vents.
• Non ducted: Blows air straight down from a ceiling assembly.

Type

• Rooftop: The standard RV install over a 14 x 14 inch opening.
• Quiet: Look for a published dB figure like RecPro's.
• Low profile: Better for tall rigs and low garages.
• Heat pump: Adds efficient heat in mild weather; see our best rv air conditioner with heat pump picks.
• Ducted: Quieter and more even; our best ducted rv air conditioner guide covers them.
• Non ducted: Simpler and common in trailers.
• Inverter: Variable-speed compressors that ramp up gradually.
• 12v: Battery-powered units for off-grid rigs; see our best 12v rv air conditioner guide.
• Portable: Window or floor units, not rooftop replacements.

Features worth paying for

• Heat pump: Useful for shoulder seasons; our three picks are cool only.
• Heat strip: An electric add-on that takes the chill off; check if your ceiling assembly supports one.
• Remote: The RecPro includes one; many others rely on a wall thermostat.
• Soft start: An add-on that eases startup surge, helpful on small generators or 30 amp service.

Match specs to your rig (30A/50A, 12V/120V, dimensions)

All three picks run on 120V shore or generator power, not 12V. A single 13,500 BTU unit suits 30 amp service, but running a second unit usually needs 50 amp. Check the roof opening, roof load and height, since shrouds range from low to medium profile.

Installation: DIY or pro

A same-size swap on an existing 14 x 14 opening is a common DIY job for handy owners with a helper, since these units weigh roughly 80 to 115 pounds per their listings. New openings, ducted systems and thermostat wiring are best left to an RV technician.

Power use & boondocking

A rooftop AC is the biggest power user in most RVs; RecPro lists 1,300 W. Boondocking takes a generator sized for the startup surge or a large battery and inverter system.

Warranty & support

None of our three listings states a warranty length. Check terms with RecPro, Coleman-Mach or Dometic, and ask whether DIY installation affects coverage.

How much should you spend?

• Under $700: No credible 13,500 BTU rooftop units at this price.
• Under $1000: Solid 13.5K units like the RecPro and the MACH 3 Plus.
• Under $1500: Inverter and heat pump 13.5K models.
• Under $2000: Premium low-profile units like the Penguin II.

A 13500 btu rv air conditioner fits most travel trailers and smaller fifth wheels, and it is usually the right size when you replace a factory 13.5K unit. It draws less power than a 15,000 BTU model, which helps on 30 amp service and smaller generators. Long rigs in hot climates may need a 15K unit or a second AC. If you have searched for best 13500 btu rv air conditioner reddit threads or 13500 btu rv air conditioner reviews, our practical answer stays the same: match the BTU to your rig's size and climate. That goes for the best 13500 btu rooftop ac for rv and the best 13500 btu camper air conditioner alike.

What is the best 13500 btu RV air conditioner?

The RecPro 13.5K Non-Ducted is the best 13500 BTU RV air conditioner for most owners. It includes a remote and touch panel, lists a 59.7 dB noise level and has the strongest rating pool in this size. The Coleman-Mach MACH 3 Plus is the budget pick, and the Dometic Penguin II is the premium choice.

What size RV air conditioner do I need?

Most travel trailers and smaller fifth wheels use a single 13,500 BTU unit. Larger rigs, hot climates or lots of windows may need 15,000 BTU or two units. Your electrical service matters too: 30 amp rigs usually run one AC, while 50 amp rigs can often run two.

How long does a RV air conditioner last?

Makers do not publish a fixed lifespan. Life depends on how many hours it runs, road vibration, roof seals and maintenance. Cleaning filters and coils, keeping the roof gasket sealed and checking the fan motor help it last. Replace it when cooling drops sharply or repairs cost close to a new unit.

Is a RV air conditioner worth it?

Yes, if you camp in warm weather. A rooftop AC keeps the RV livable for sleep, pets and electronics, and it removes humidity. If you only camp in cool mountain spots in spring and fall, fans and shade may be enough, but most summer campers rely on one.

How do you clean a RV air conditioner?

Wash the return air filters in warm soapy water and let them dry. With power off, remove the shroud and gently clean the coils with a soft brush or coil cleaner, and clear leaves from the drain area. Check the roof gasket for leaks while the shroud is off.

What is the most reliable RV air conditioner brand?

Dometic, Coleman-Mach and RecPro all sell 13,500 BTU rooftop units with established rating pools on Amazon. Reliability depends more on the model, installation quality and maintenance than the brand. Look for a clear warranty, easy parts availability and solid owner ratings before you choose.

The RecPro 13.5K is our best 13500 btu rv air conditioner for its built-in controls, published noise level and strong ratings. The Coleman-Mach MACH 3 Plus is the budget pick, and the low-profile Dometic Penguin II is the premium upgrade. Check price on Amazon, and see all sizes in our best rv air conditioner guide.
