Mini Split for RV Garages in the Phoenix Metro Area

RV garages are one of the fastest-growing home features in the Phoenix metro area — particularly in communities like Queen Creek, San Tan Valley, Gilbert, Chandler, Peoria, and Surprise where larger lot sizes allow for the oversized structures needed to house an RV. A proper RV garage in Arizona needs dedicated climate control — and a ductless mini split system is the most effective and efficient solution.

Why RV Garages in Arizona Need Dedicated Cooling

• Massive thermal mass: RV garages are large — typically 1,200 to 2,500 sq ft — with high ceilings (14–16 feet) and often minimal insulation
• Metal and concrete construction: Common RV garage materials absorb and radiate heat aggressively
• Large overhead doors: RV garage doors have significant air infiltration and thermal conductance
• Extreme interior temperatures: An uncooled RV garage in Phoenix in July reaches 135–145°F — hot enough to damage your RV's interior, seals, batteries, and electronics
• Work and hobby use: Most RV garage owners use the space for maintenance, hobbies, and projects requiring human-tolerable temperatures

What Size Mini Split Does an RV Garage Need?

• Small RV garage (800–1,200 sq ft): 24,000 BTU (2 ton) — single zone
• Standard RV garage (1,200–1,800 sq ft): 36,000 BTU (3 ton) — single zone or 2-zone
• Large RV garage / shop combo (1,800–2,500 sq ft): 48,000–60,000 BTU — multi-zone or commercial mini split

Mini Split vs. Window Unit vs. Portable AC for RV Garages

• vs. Window units: Mini splits are 2–3x more efficient, far quieter, don't require a window opening, and can handle the BTU demands that window units can't match
• vs. Portable ACs: Portable units recirculate heat back into the space and are woefully undersized for Arizona's heat. They are temporary solutions at best
• vs. Mini splits: Nothing competes for an RV garage application in Phoenix metro's climate

Electrical Requirements for RV Garage Mini Splits

Large RV garage mini splits (2 ton and above) require dedicated 240V circuits with appropriate amperage. Many RV garages already have significant electrical service due to RV plug requirements — we coordinate with your electrical panel capacity.
