Why Your Caravan Air Conditioner Needs a Specialist (It's Not Like Home AC!)

A caravan or motorhome air conditioning unit is a very different beast to the one cooling your house. It’s designed to be bounced around the country, run off generators, and handle extreme sun.

You can’t trust a standard repair guy with this setup; you need an expert who understands the unique mechanical and electrical strains of a mobile aircon unit.

Tricky Power Systems (12V/240V)

Caravan air conditioning runs on complex, multi voltage systems that household electricians don't usually touch.

⚡ Dual Power: Your system has to run off standard 240V site power and often off battery power (via 12V or solar).

🔎 Expert Check: Our technicians are great at finding these tricky power problems. They make sure your unit runs efficiently without draining your batteries or tripping your generator.

Vibration & Sun Stress on Your Air Conditioner

Your roof unit is always being battered by the elements, so if it's not fitted properly, it breaks down too soon.

🫨 Vibration Damage: Constant road vibration loosens screws and shakes parts out of alignment. We fix the mounts to stop noise and prevent expensive compressor failure.

🌧️ Weather Leaks: We make sure all roof seals and plumbing connections are good, which prevents leaks that can ruin the ceiling and wiring of your caravan.

Our Full Service: Guaranteed Reliability Before You Go

Before you hit the road, your caravan aircon needs more than a quick look over!

Our complete service finds all the hidden problems before they turn into a major breakdown when you're touring.

We check everything to make sure your AC is ready for the long haul.

Stopping That Annoying Vibration & Noise

Road travel puts immense strain on a roof unit. Our service targets the physical issues that make the unit noisy and inefficient:

🫨 Vibration Check: Constant road vibration shakes everything out of alignment and loosens screws. We fix the mounts to stop the noise and save you from an expensive compressor bill.

🧼 Deep Clean: We deep clean the coils to get rid of mould and dirt. That's the key to making sure you get the best cooling and heating everywhere in your caravan.

Checking Compressor Health & Power Draw

The compressor unit is the heart of your air conditioner; if it goes, your whole system is dead!

⚙️ We run checks to look at the compressor and make sure the refrigerant gas is spot on.

🔋 We check the unit's power use against the battery. That's how we make sure it runs efficiently and won't flatten your battery or trip the generator.
