When the air conditioning stops working in an RV or motorhome, Texas heat can turn a trip into a miserable experience very quickly. Kool2U provides professional mobile RV AC repair in San Antonio, New Braunfels, Boerne and surrounding areas.
​
We service both major types of RV air conditioning systems:
• Dash and chassis AC that cools the driver and passenger area while traveling
• Rooftop and house AC that cools the RV living area
​
Kool2U can come to your home, RV park, campground, storage facility or other supported location to diagnose and repair many RV AC problems where the vehicle is located.
​
RV AC not cooling?
​
Have the RV make, model, approximate year, location and whether the problem involves the dash AC or living area AC available when you call.
​
RV Dash AC & Rooftop AC Repair
“RV AC repair” can mean two very different systems.
​
RV Dash & Chassis AC
The dash AC operates similarly to the air conditioning system in a car or truck and cools the driver's cab while the RV is being driven.
These systems typically include:
• Compressor
• Condenser
• Evaporator
• Refrigerant lines
• Expansion device
• Blower motor
• Electrical controls
• Refrigerant and pressure sensors
Kool2U specializes in automotive AC diagnostics, refrigerant leak detection and repair.
​
RV Rooftop & House AC
The rooftop or house AC cools the RV's living area when connected to shore power, generator power or another supported electrical source.
These systems may involve:
• Rooftop AC units
• Thermostats
• Fan motors
• Capacitors
• Compressors
• Control boards
• Electrical circuits
• Airflow problems
• Freeze ups
• Drainage problems
Kool2U can diagnose and repair many problems affecting RV living area AC systems.
​
Mobile RV AC Repair That Comes to You
Moving a large motorhome solely for AC diagnosis can be inconvenient, especially if the RV is already parked at a campground or storage facility.
Kool2U provides mobile RV AC service at locations including:
• RV parks
• Campgrounds
• Homes
• RV storage facilities
• Commercial facilities
• Fleet yards
• Other supported service locations
Mobile service can eliminate an unnecessary trip to an RV dealership or repair facility for many AC problems.
​
RVs & Motorhomes We Service
Kool2U provides AC diagnostics and repair for many recreational vehicles, including:
• Class A motorhomes
• Class B motorhomes
• Class C motorhomes
• Camper vans
• Travel trailers
• Fifth wheels
• Toy haulers
• Other supported recreational vehicles
Service requirements vary by RV and AC system.
Call 210 374 5727 with the make, model and type of AC problem so we can determine the appropriate service.
​
RV Dash AC Problems We Diagnose
Kool2U diagnoses RV chassis and dash AC problems including:
• Dash AC blowing warm or hot air
• Weak cooling
• Intermittent cooling
• AC cold while driving but warm at idle
• Refrigerant leaks
• Compressor problems
• Condenser failures
• Evaporator leaks
• Expansion valve problems
• Blower motor failures
• Electrical faults
• Pressure sensor problems
• Wiring problems
• HVAC control problems
• Repeated refrigerant loss
​
RV Rooftop & House AC Problems We Diagnose
Living area AC systems can fail for very different reasons than automotive dash AC systems.
Kool2U diagnoses problems including:
• Rooftop AC not turning on
• AC running but not cooling
• Weak airflow
• Unit freezing up
• Fan not running
• Compressor not starting
• AC cycling on and off
• Thermostat problems
• Electrical failures
• Capacitor problems
• Control problems
• Unusual noises
• Water or drainage issues
• One AC unit working while another does not
​
RV Dash AC Leak Detection
Refrigerant leaks are a common cause of poor dash AC performance.
Large RV systems can contain long refrigerant lines and multiple connections, making some leaks difficult to locate.
Kool2U uses its proprietary AC diagnostic and leak detection process to help identify the source of refrigerant loss before repairs are recommended.
Potential leak sources can include:
• Refrigerant hoses
• Hose crimps
• O rings and fittings
• Compressors
• Condensers
• Evaporators
• Service ports
• Expansion valves
• Connections and seals
Finding the actual leak can prevent repeated recharges and unnecessary parts replacement.
​
RV AC Recharge & Refrigerant Service
If an RV dash AC system is low on refrigerant, Kool2U evaluates the system to determine why.
Depending on the vehicle and system, service may include:
• Refrigerant recovery
• Vacuum testing
• Leak testing
• Refrigerant recharge
• Pressure testing
• Temperature testing
• Verification of AC performance
Kool2U services supported R134a and R1234yf systems, as well as other supported mobile AC applications.
​
RV Dash AC Compressor Diagnosis
An RV dash AC compressor can be expensive to replace.
Before recommending replacement, Kool2U evaluates whether the compressor has actually failed or whether another issue is preventing the system from operating properly.
Possible causes can include:
• Refrigerant loss
• Electrical problems
• Compressor clutch or control faults
• Pressure sensor failures
• Restricted refrigerant flow
• Condenser airflow problems
• Internal compressor failure
Our diagnostic first approach is designed to identify the cause rather than simply replace parts based on symptoms.
​
RV Rooftop AC Electrical Diagnosis
Many rooftop and living-area AC failures are electrical rather than refrigerant related.
Testing may involve:
• Power supply
• Thermostat operation
• Capacitors
• Fan motors
• Compressor starting circuits
• Control boards
• Wiring and connections
• Breakers and protection devices
• Temperature controls
Correctly identifying the electrical failure can prevent unnecessary replacement of an entire rooftop AC unit.
​
One RV Can Have Multiple AC Problems
An RV may have:
• A dash AC problem
• A rooftop AC problem
• Multiple rooftop units
• More than one problem at the same time
For example, the dash AC may have a refrigerant leak while a rooftop unit has an electrical or airflow problem.
Because Kool2U works on both types of systems, we can help determine which system is actually causing the complaint.
​
RV AC Diagnosis Before Parts Replacement
Kool2U takes a diagnostic first approach.
A system that does not cool properly does not automatically need a compressor.
A rooftop unit that will not start does not automatically need to be replaced.
A dash system that is low on refrigerant should not simply be recharged repeatedly without determining why the refrigerant is escaping.
Our goal is to identify the underlying problem before recommending the repair.
