By Hardcastle's RV Editors

10 min read6 products evaluated

A 13,500 BTU rooftop air conditioner is the standard size for most travel trailers and many fifth wheels. Because it fits the common 14 inch vent opening, the choice is between brand lines, weight, airflow and whether you want a heat element.

The six picks run from about 800 to 1,176 dollars. They include three Coleman-Mach models, a Dometic, a RecPro and a VEVOR.

What Matters Before You Choose a 13500 Btu RV Air Conditioner

Key buying criteria so you get the right fit the first time.

  1. Ducted or non-ducted

    A ducted unit sends air through ceiling ducts, while a non-ducted unit uses an air distribution box. Replacing one with the other usually means changes inside the coach. Check which your rig has and match it.

  2. Roof opening

    Most RVs have a 14.25 by 14.25 inch roof opening, which most of these units fit. A different opening needs an adapter. Measure the opening before ordering.

  3. Weight and profile

    A lighter unit eases the roof load and the install. A low-profile unit reduces drag and clearance. Check the stated weight and height.

  4. Heat element vs cooling only

    A 5,600 BTU heat element warms a chilly morning but is not a heat pump. Cooling-only units are simpler. Decide whether you want heat from the unit.

  5. Power draw

    A 13,500 BTU unit draws a lot at startup. A soft start helps on a generator. Check the amp draw if you run on 30 amp or a small generator.

Before You Bring One Home

Is 13,500 BTU enough for a travel trailer?

For most trailers up to about 30 feet, yes. Longer or heavily glazed rigs may need two units.

What mistake do buyers make?

They ignore ducted vs non-ducted. Check your rig first.

Is the Dometic worth the premium?

If you want a light unit with a trusted brand, yes. The VEVOR costs less.

How do I install a rooftop unit?

Remove the old unit, set the new one on the gasket and secure it from inside. Connect the power and test.

Should I add a soft start?

Yes, for generator use. A soft start cuts the startup surge.
