18K Buying Guide

One 18,000 BTU platform. Three ways to control your RV climate.

Every 18K model gives larger RVs more cooling headroom. The real choice is simple: cooling only, light electric warmth, or heat-pump comfort for more seasons.

1

Summer heat only?

Choose the 18K cooling-only model for strong summer performance.

2

Need light electric warmth?

Choose the PTC model to take the chill off cool mornings.

3

Want the widest comfort range?

Choose Pro Max with heat pump for the most complete setup.

Quick buying notes

Use these simple rules before choosing your model.

Is 18K too much for every RV? Not every camper needs it. 18K makes the most sense for larger cabins, slide-outs, wide windows, hot regions, or older 13.5K/15K units that run constantly.
PTC vs heat pump? PTC is light supplemental warmth. Heat pump is the stronger built-in heating choice for broader shoulder-season comfort.
Can rooftop heating replace a furnace? No. PTC and heat pump models help with mild cold, but freezing conditions still call for a dedicated RV furnace.
Will it fit my RV roof? These models are designed around the common 14.25″ × 14.25″ RV roof opening, but confirm roof thickness, duct setup, clearance, and power before installation.
