RV AC & Cooling Service in Hobe Sound, FL
RV AC repair in Hobe Sound, FL. Rooftop AC, thermostats, refrigerant, ductwork, dual systems, compressors. Call 772-758-0499.
In South Florida, your RV's AC isn't a luxury. It's survival equipment. From April through October, interior temperatures can hit 130 degrees F without cooling. That puts stress on every component: compressors, capacitors, fan motors, thermostats, and ductwork. When your AC stops blowing cold, you've got hours before the heat becomes dangerous for you, your pets, and your electronics.
TL;DR

DetailsCommon Issues We See in Florida
Florida's heat creates a unique AC torture test. Your rooftop unit runs 8 or more months per year, often cycling nonstop for 12 to 14 hours a day in peak summer. That's double the runtime compared to an RV in Michigan or Colorado. According to Dometic's maintenance guidelines, AC units in high-use environments need coil cleaning every 6 months and capacitor inspection annually. We see capacitor failures more than any other AC problem in Hobe Sound. A $15 capacitor that overheats and pops can shut down your entire cooling system on the hottest day of the year. We also see a lot of mold in ductwork. Florida's humidity feeds mold growth inside the ducts, especially when the AC cycles off overnight and condensation sits in the system.

RV AC & Cooling Service FAQ
Common questions from RV owners in Hobe Sound and Martin County.
Why is my RV AC blowing warm air?
Most common causes: low refrigerant, bad capacitor, dirty evaporator coil, or a failed compressor. We'll diagnose which one and give you a price before starting. Capacitor failure is the #1 cause we see in Florida.
How much does RV AC replacement cost?
A single rooftop AC unit replacement typically runs $1,200 to $2,500 installed, depending on the brand and BTU rating. Repair of existing units ranges from $95 to $800.
Can you add a second AC to my RV?
Yes. Dual AC installation is one of our most popular services. You'll need a 50-amp electrical system to run two units simultaneously. We handle the full installation including mounting, wiring, and zone control setup.
How often should I clean my RV AC coils?
In Florida, every 6 months. Dometic recommends annual cleaning, but our climate demands more frequent maintenance. Dirty coils reduce cooling efficiency by up to 30% and force the compressor to work harder.
My RV AC smells musty. What's causing it?
Mold in the ductwork or on the evaporator coil. Florida's humidity is the perfect breeding ground. We clean the coils, treat the ducts with antimicrobial solution, and check the condensate drain to prevent future growth.
Is R-22 refrigerant still available for my older RV AC?
R-22 has been phased out, but we can still recharge existing R-22 systems with reclaimed refrigerant. For older units, we may recommend upgrading to a new R-410A unit, which is more efficient and uses readily available refrigerant.
Why does my RV AC freeze up?
Low refrigerant, restricted airflow (dirty filter or blocked return), or a failing fan motor. All three cause the evaporator coil temperature to drop below freezing, forming ice. We'll find the root cause and fix it.
Can you install a mini-split in my RV?
We can, though it's not common. Mini-splits work well in larger Class A motorhomes with enough wall space for the indoor unit. We'll assess your rig and give you an honest recommendation on whether it makes sense.
