When Texas heat hits full throttle (and you’re sweating in places you didn’t know could sweat), a reliable RV air conditioner isn’t just a luxury — it’s survival. Whether your old unit finally tapped out or you’re upgrading for better cooling power, a properly installed RV A/C system makes every trip more comfortable, safe, and enjoyable.
As Certified RV Technicians, we install rooftop A/C units almost daily, and we’ve seen just about everything — from 20-year-old dinosaurs barely hanging on, to brand-new units that weren’t installed correctly from the start. So let’s walk through what goes into a professional RV A/C installation and what RV owners should expect.

🔧 Why Replacing Your RV A/C Matters
An air conditioner doesn’t just “go out.” It usually gives warning signs, like:
Uneven cooling or warm air
Loud grinding or squealing
Freezing coils
Tripping breakers
Water leaks inside the RV
Sometimes repairs make sense. Other times — especially with older units like the Dometic Brisk II or a failing Coleman Mach — replacement is the safer and more cost-effective option.

❄️ What’s Involved in an RV A/C Installation?
1. Safe Removal of the Old Unit
We disconnect power, lift the old rooftop unit, and remove the ceiling assembly inside.
Many older RVs have brittle seals or damaged gaskets — we catch those before they cause leaks.
2. Electrical & Compatibility Check
We verify:
Correct amperage
Proper wiring
Thermostat compatibility
Duct vs. non-duct systems
This is where DIY jobs often go wrong (and why they end with smoke or crying).
3. Installing the New Rooftop A/C
We mount the new unit, replace the gasket, torque everything to manufacturer specs, and ensure the seal is watertight — the Texas storms are not forgiving!
4. Inside Assembly & Thermostat Setup
We install:
New ceiling plenum
Return air filters
Thermostat (if needed)
Proper airflow adjustments
5. Full System Testing
We check:
Temperature drop
Fan speeds
Compressor cycle
Airflow in every duct
Breaker load
You get the peace of mind knowing it’s cooling like it should.

💰 How Much Does an RV A/C Installation Cost?
On average, RV A/C installations range from:
$1,200–$2,800 depending on
Brand (Coleman, Dometic, Furrion)
13.5K vs 15K/18k BTU
Ducted vs non-ducted
Thermostat/control board needs
At RV Rescue Rangers, we provide upfront estimates and honest recommendations — no upsells, no guesswork.

🧰 Why Choose a Certified RV Technician?
Because your RV isn’t a house… and it’s not a car either.
It’s a rolling puzzle of electrical, HVAC, and structural systems that all have to work together.
A professional ensures:
No electrical hazards
No roof damage
No leaks
No warranty issues
Plus, a correctly installed A/C runs colder, lasts longer, and performs better in extreme heat.
