RV air conditioners work hard in Texas. Rooftop units bake in direct sun while trying to cool your interior, and the temperature difference they’re fighting can exceed fifty degrees on summer afternoons. When your AC struggles or fails entirely, the cause isn’t always obvious.

We diagnose and repair both rooftop and basement air conditioning systems. Common problems include failed capacitors, worn fan motors, refrigerant leaks, frozen coils, and control board failures. Sometimes the issue isn’t the AC unit at all—inadequate shore power, voltage drops, or thermostat problems can all present as air conditioning failures.

Dometic and Coleman units dominate the RV market, but we also service Advent, Furrion, GE, and other brands. If your unit is repairable, we’ll repair it. If replacement makes more sense—because of the unit’s age, refrigerant type, or repair cost relative to replacement—we’ll tell you that directly and explain why.

Maintenance extends AC lifespan significantly. We clean coils, check capacitors before they fail, verify refrigerant levels, and inspect the seals and gaskets that keep conditioned air inside your RV. For full-time RVers whose systems run most of the year, annual maintenance prevents the emergency calls that always seem to happen on the hottest weekend of summer.

RV refrigerators operate on principles different from residential units, and this difference confuses many technicians who learned on household appliances. Absorption refrigerators—the type found in most RVs—use heat and gravity rather than a compressor. They’re reliable when working properly but unforgiving when something goes wrong with their leveling, ventilation, or gas supply.

We repair both absorption and compressor-based RV refrigerators. Absorption units commonly fail due to cooling unit degradation, control board problems, thermocouple issues, and burner assembly malfunctions. Compressor units share more in common with residential refrigerators but have their own failure patterns related to the vibration and power fluctuations of RV life.

Norcold and Dometic manufacture most absorption RV refrigerators. We work on all models, including older units that other technicians refuse to touch and newer residential-style units that require different diagnostic approaches.

Refrigerator problems often present gradually—the unit stops getting quite as cold, takes longer to cool down, or works fine on electricity but fails on propane. These early warnings give you time to schedule service before complete failure. A refrigerator that suddenly stops entirely while running on LP gas might indicate a more serious problem with your propane system that affects other appliances too.

For units with failed cooling systems, we provide honest assessments about repair versus replacement. Cooling unit replacement is expensive, and for older refrigerators, that cost sometimes approaches or exceeds replacement cost. We’ll give you the numbers and help you make an informed decision.

RV furnaces operate on propane and 12-volt electricity, making them dependent on two systems that can each cause failures. A furnace that won’t ignite might have a gas supply problem, an ignition board failure, a faulty sail switch, a blocked exhaust vent, or simply a dead battery that can’t power the blower.

We service Suburban, Atwood (now Dometic), and other RV furnace brands. Common repairs include ignition board replacement, blower motor service, sail switch adjustment or replacement, thermostat troubleshooting, and gas valve diagnosis. We also address the ducting problems that cause some areas of your RV to roast while others stay cold.

Furnace maintenance matters more than most RV owners realize. Insects and mud daubers build nests in burner tubes and exhaust vents. Dust accumulates in blower assemblies. Combustion chambers develop cracks that create carbon monoxide risks. A pre-season inspection catches these issues before the first cold night when you discover your furnace won’t light.

Propane leak testing is part of every furnace service call. Your furnace connects to the same LP system as your water heater, refrigerator, and cooktop. Problems in the supply lines, regulator, or tank connections affect all these appliances and create safety risks beyond just equipment failure.

RV water heaters come in two main types: tank-style heaters that store six to ten gallons of hot water, and tankless on-demand units that heat water as you use it. Both types have their advantages and their common failure points.

Tank water heaters from Suburban and Atwood use propane burners, electric heating elements, or both. The anode rod inside the tank protects against corrosion but requires periodic replacement—a maintenance item most RV owners neglect until their tank develops leaks. We replace anode rods, service burner assemblies, test and replace electric elements, and address the control board failures that prevent proper operation.

Tankless water heaters from Girard, Truma, and other manufacturers offer unlimited hot water but depend on adequate water flow and proper gas pressure. Error codes on these units often indicate problems outside the water heater itself—low water pressure, inadequate LP supply, or electrical issues. Proper diagnosis prevents unnecessary parts replacement.

Winterization failures cause many water heater problems we see in spring. Water left in the tank or lines expands when frozen, cracking tanks and rupturing fittings. If you’re unsure whether your water heater survived winter storage, we can inspect for damage before you discover it through a flooded compartment.

RV electrical systems combine 120-volt AC power from shore connections or generators with 12-volt DC power from batteries. These systems interact through converters and inverters, and problems in one system often masquerade as problems in the other.

We troubleshoot and repair the full range of RV electrical issues. Shore power problems include damaged cords, faulty inlets, and progressive dynamics issues with transfer switches. Converter failures leave batteries uncharged even when plugged in. Inverter problems prevent 120-volt appliance operation when off-grid. Battery issues range from simple dead cells to wiring problems that prevent proper charging.

12-volt circuit problems cause mysterious failures throughout your RV. Lights that don’t work, slides that won’t extend, fans that won’t run, and water pumps that stay silent all trace back to the 12-volt system. We locate shorts, repair damaged wiring, replace fuses and breakers, and address the corrosion that plagues RV electrical connections.

For full-time RVers and those who spend significant time off-grid, we offer electrical system upgrades. Lithium battery conversions provide more usable power with less weight and longer lifespan than lead-acid batteries. Solar panel installations reduce generator dependence and extend your ability to camp without hookups. Inverter additions or upgrades let you run more appliances when away from shore power.

RV plumbing systems include fresh water storage and delivery, gray water collection from sinks and showers, and black water handling from toilets. Problems in any of these systems range from minor annoyances to situations that make your RV uninhabitable.

Fresh water system repairs cover water pumps that won’t prime or won’t shut off, leaking fittings and connections, failed pressure regulators, and water filtration systems. We locate leaks behind walls and under floors where water damage occurs invisibly until the problem becomes severe.

We service all RV toilet types including Thetford and Dometic gravity-flush toilets, macerating toilets, composting systems, and cassette toilets. Common repairs include valve seal replacement, water connection repairs, and addressing the pedal mechanisms that break with regular use. For toilets beyond repair, we can discuss replacement options that might better suit your usage patterns.

Holding tank issues include sensor malfunctions that give false readings, valve problems at the dump connections, tank damage, and vent blockages that create pressure problems. The sensors in holding tanks often fail or give inaccurate readings due to buildup on the sensor probes—sometimes cleaning restores function, other times replacement is necessary.

Water heater bypass valves, winterization systems, and low-point drains all factor into RV plumbing. If you’re preparing for winter storage or recovering from inadequate winterization, we can inspect your entire water system for damage and address any problems before they worsen.

RV roofs fail gradually and invisibly. Water intrusion begins at seams, around penetrations, and at the edges where the roof meets the sidewalls. By the time you notice water stains on interior ceilings, damage has been occurring for months or years.

We inspect and repair all RV roof types. Rubber roofs—both EPDM and TPO—require different sealants and repair approaches than fiberglass or aluminum roofs. Each material ages differently and fails in predictable patterns that experienced technicians recognize.

Sealant maintenance prevents most roof leaks. The caulk around roof penetrations—air conditioners, vents, antennas, skylights, and refrigerator vents—deteriorates with UV exposure and temperature cycling. Resealing these penetrations every few years costs far less than repairing water-damaged walls and subfloors.

We repair existing damage including delaminating fiberglass, punctures and tears in rubber roofing, failed seams, and soft spots indicating water damage to the underlying structure. For roofs with widespread deterioration, we’ll assess whether spot repairs make sense or whether the damage indicates need for more comprehensive restoration.

Roof inspections should happen at least annually and after any incident involving low-clearance contact. The cost of an inspection is trivial compared to the structural repairs that result from undetected water intrusion.

Built-in RV generators provide electrical independence from shore power, but they require maintenance that many owners neglect. A generator that sits unused for months may not start when you need it. A generator that runs without regular service will eventually fail, usually at the worst possible time.

We service Onan, Cummins, Generac, Champion, and other generator brands found in RVs. Routine maintenance includes oil changes, filter replacement, spark plug service, and fuel system inspection. We test electrical output to verify your generator produces clean power at proper voltage.

Common generator problems include starting failures from stale fuel or dead starting batteries, fuel delivery issues, carburetor problems in gasoline units, governor malfunctions causing speed instability, and electrical output problems where the engine runs but doesn’t produce proper power.

For generators that won’t run or won’t produce power, we diagnose before recommending repairs. Some problems—a failed control board, a damaged alternator—cost more to repair than the generator is worth, particularly on older units. We’ll give you honest numbers and let you decide.

Exercise schedules matter for generator longevity. Generators that sit unused develop problems from stale fuel, dried seals, and stuck components. Running your generator under load for thirty minutes monthly prevents many common failures.

Propane powers your RV’s furnace, water heater, refrigerator, cooktop, and sometimes your generator. The LP system that delivers gas to these appliances requires proper pressure regulation and leak-free connections throughout.

We test LP systems for leaks using professional detection equipment more sensitive than soapy water. Gas leaks create both safety hazards and operational problems—appliances running on inadequate pressure perform poorly or fail to ignite. A thorough leak test covers all connections from the tank through the regulator to every appliance.

Regulator problems cause symptoms that seem unrelated to gas supply. A failing regulator might allow your furnace to work while your water heater struggles. Regulators wear out over time and should be replaced according to manufacturer schedules, typically every ten to fifteen years.

Propane appliances require periodic inspection of burner assemblies, ignition systems, and venting. We check these components when servicing individual appliances but can also perform comprehensive LP system inspections that cover the entire propane installation from tank to appliances.

If your RV has been in storage, especially with the propane system shut off, air in the lines can prevent appliances from lighting on the first attempt. This is normal—it just takes time for gas to reach each appliance. Persistent ignition problems after clearing the lines indicate issues that need diagnosis.

Slide-outs expand your living space but add mechanical complexity. Hydraulic, electric, and cable-driven systems each have different failure modes and maintenance requirements.

Hydraulic slide systems use fluid pressure to extend and retract the room. Leaks, pump failures, valve problems, and seal deterioration all cause operational issues. We diagnose hydraulic problems, repair or replace failed components, and address the fluid contamination that causes many hydraulic failures.

Electric slide systems use motors and gear drives. Motor failures, stripped gears, broken shear pins, and control board problems prevent proper operation. Schwintek, Power Gear, and Lippert systems each have their known failure points and repair procedures.

Cable-driven systems are less common but still found in many trailers. Cable stretch, broken cables, and pulley problems cause slides to bind, move unevenly, or refuse to fully extend or retract.

Alignment issues cause binding and uneven seal contact regardless of drive system type. Slides that travel out of square put stress on mechanisms and allow water intrusion around seals. Adjustment often resolves operational problems without parts replacement.

Slide seals keep weather outside but deteriorate with UV exposure and wear. Damaged seals allow water intrusion and air infiltration that undermine your RV’s comfort and eventually its structure.

Your RV’s exterior includes multiple systems beyond the roof that require periodic attention. Entry door hardware wears out, baggage door hinges fail, and compartment locks break. Window seals deteriorate, allowing water intrusion and air leaks.

Running lights, clearance lights, brake lights, and turn signals are legal requirements and safety necessities. We diagnose lighting problems that might originate in the lights themselves, in wiring, or in the tow vehicle connection for trailers.

Ladder, bumper, and hitch repairs address the structural components that take abuse from road debris, parking incidents, and regular use. Proper repair maintains both function and appearance.

Fifth wheel pin boxes and king pins require periodic inspection for wear and proper lubrication. Trailer hitch components including jacks, couplers, and safety chains should all function properly before every trip.

We come to your location across the Texas Hill Country. Whether you’re at an RV park in Fredericksburg, a river campground near Ingram, a ranch property outside Center Point, or broken down on I-10 near Comfort, we bring tools and expertise to you.

Diagnosis comes first. We identify what’s actually wrong before recommending repairs. Sometimes the obvious symptom points to a less obvious cause—we look for the real problem, not just the superficial one.

We explain what we find in plain language. You’ll understand what’s wrong, what it takes to fix it, and what happens if you don’t fix it. For problems with multiple solutions, we’ll outline options with honest assessments of cost, longevity, and trade-offs.

Parts availability affects repair timelines. We stock common components, but some parts require ordering. When that happens, we’ll give you realistic timelines and help you decide whether to wait, pursue temporary solutions, or seek alternatives.

Our work is guaranteed. If we repair something and the same problem recurs due to our workmanship, we’ll address it.
