How Much Does RV AC Repair Cost in 2026?

Your RV AC quits in the middle of a Florida summer and the first question is always: how much is this going to cost? As someone who has been fixing RV ACs for 17 years, I can give you real numbers — not vague ranges from websites that have never held a wrench.

Common RV AC Repair Costs

Here is what we typically see at Sebastian RV Repair:

• Capacitor replacement: $150 - $250 (parts + labor). This is the single most common AC repair we do. Takes about 30 minutes
• Fan motor replacement: $250 - $450. The second most common failure, especially on units over 5 years old
• Compressor replacement: $400 - $800. At this price point, we often discuss whether a full unit replacement makes more sense
• Thermostat replacement: $120 - $280. Depends on analog vs. digital and brand compatibility
• Full rooftop AC unit replacement: $800 - $1,800 installed. Includes removal of old unit, mounting, wiring, and testing
• Refrigerant recharge: $150 - $300. Note: if your system is low on refrigerant, there is a leak somewhere that needs fixing

Why Prices Vary

Three factors drive the cost: the brand (Dometic parts cost more than Coleman), the age of your unit (older units may need discontinued parts), and accessibility (some rooftop units are harder to reach than others).

When to Repair vs. Replace

My general rule: if the repair costs more than 50% of a new unit and your AC is over 8 years old, replacement usually makes more financial sense. A new Dometic or Coleman rooftop unit will give you another 10-15 years of reliable cooling.
