Essential Tips in Repairing RV Air Conditioner


Summer is right around the corner, and it is the best time to hang out with family and friends. Well, an RV road trip guarantees an unforgettable experience to better enjoy the scenery. One thing to consider is the air conditioning system of the car to ensure a comfortable ride.

Not enough money to hire a technician? The good news is that you alone can easily repair a faulty air conditioning system. Knowing the basics on RV repairs will save you money, which include:

  • Sealed System

RV air conditioning has two main systems and one is the sealed system. It is responsible for the inner functions of the air conditioners to produce cool air. This part includes the condenser, evaporator, and compressor.

  • Air-moving system

In contrast, the air-moving system is made up of a motor and dual fans. Each fan is connected to the condenser and evaporator to circulate air inside the RV.

Such air conditioning systems have a chance to fail but there are ways to resolve it.

Common RV Air Conditioner Problems

The following issues often take place on RV air conditioning systems, including:

  • RV Air Conditioner Does Not Turn On

One of the best activities during an RV trip is grilling BBQs out of the woods. There are cases when you go back to the vehicle and the air conditioner is not delivering cold air.

The first thing to do is check the RV’s power supply and then plug it into a 110-volt outlet. If it works, you are all good.

Or maybe the problem is on the breaker, so have a quick check on it. Use a multimeter to test voltages if needed.

Do not ever call 911 right away when such things happen. Perform all the said remedies, and if none work, then you can ask a technician to help you.

  • RV Air Conditioner Gets Hotter

In some cases, the air conditioning system cannot keep cool air inside the RV for various reasons.

Among its potential causes is that maybe the air conditioner is now obsolete and demands a new unit. AC systems can last for a few years before replacement.

It is also normal for some RVs not to be able to sustain cold air during summer. It depends on the size of the vehicle whether you need to add another air conditioning system or not.

Last but not least, maybe the air filters are dirty. Grime buildup  impacts the overall performance of the unit, including its efficiency to deliver cold air.

  • RV Air Conditioner Freezes Up

An AC system could freeze up during harsh conditions. It may clog the air filters or cause leaks that affect its functionality.
