Caravan Air Conditioning Prices: What to Expect

Jul 12, 2025

Roasting in your caravan like a Sunday lunch? Caravan and motorhome air conditioning costs range from £300 to £2,000, depending on type and setup. Want cool comfort without burning your wallet? Keep reading to find the best unit for your needs—and dodge costly cooling blunders.

The Bottom Line: What to Budget for a New Air Conditioner

A Quick Overview of the Price Range for Different Types

Caravan and motorhome air conditioning typically costs between £300 and £2,000.
This wide range depends on the type of unit, the brand, and energy efficiency ratings.
Roof-mounted, portable, and split systems all come at different price points. Some are better for larger caravans, while others suit smaller spaces or tight budgets.

Understanding the Two Main Costs: The Unit and the Installation

When budgeting, keep in mind that there are two separate costs: the air conditioning unit itself and the installation. The unit price varies significantly by type.
Installation, on the other hand, can add £200 to £500 to your total bill. This depends on whether it's a simple plug-in or a more complex rooftop fitting.

Why the Cheapest Unit Isn't Always the Best Value

It might be tempting to go for the lowest price. However, cheaper units often have lower energy efficiency or shorter lifespans. Spending more upfront on a high-quality model can pay off in the long run.

You’ll save on energy bills and enjoy fewer maintenance issues down the line.

Breaking Down the Costs: Unit Prices by Type

Rooftop Air Conditioners: Price and Feature Comparison

Roof-mounted systems are among the most popular options.
They cost between £800 and £1,500. These units provide strong cooling for larger caravans but often require a professional installation.
They also need to be securely mounted to prevent leaks and structural damage.

Under-Bunk (or Under-Bench) Models: What to Expect

While not discussed in depth above, under-bench units are another option for space-conscious caravans. They tend to fall within a similar price range to rooftop models.
Their appeal lies in their low-profile design and quieter operation.
However, installation may require more planning due to limited airflow paths.

Portable Air Conditioners: The Budget-Friendly Option

If you want something more flexible, portable air conditioners offer a solid solution.
These are priced between £300 and £700. They don’t require any structural installation and can be moved around the van as needed.
Ideal for those who only travel during hotter months or want a plug-and-play option.

Some models include smart features or compact designs tailored for smaller caravans.
Comparing features is key to finding the best value in this category.

The Hidden Cost: Installation Fees

Typical Costs for a Professional Rooftop Installation

If you're opting for a rooftop unit, expect to pay between £200 and £500 for professional installation.
This price covers sealing, wiring, and ensuring a safe, stable fit.
A correct install is essential to prevent leaks and long-term damage to your caravan.

Factors That Can Increase Installation Costs (e.g., custom wiring, structural work)

Installation costs can rise if your caravan needs extra structural support.
Custom wiring or ventilation routing might also be necessary.
Older caravans or unique layouts may require additional labour.
Always request a detailed quote before installation begins.

DIY vs. Professional Installation: A Cost-Benefit Analysis

DIY installation can save money upfront.
However, you’ll need the right tools and know-how.
Improper installation may void the warranty or cause performance issues.
Professional installers ensure everything is done correctly, which could save you money in future repairs.

Factors That Influence the Overall Cost

Key Features That Affect the Price

Reverse Cycle (Heating and Cooling) vs. Cooling Only

Reverse cycle air conditioners provide both heating and cooling.
They cost more initially but offer year-round use.
If you travel in colder months, this dual functionality is well worth considering.

Inverter Technology and Energy Efficiency

Units with inverter technology operate more efficiently by adjusting compressor speed.
They typically cost more than basic models but consume less energy.
Over time, this can lead to noticeable savings on power usage.

Brand Reputation and Warranty

Premium brands like Dometic and Truma come with higher price tags.
However, they often offer longer warranties and better after-sales support.
Buying from a trusted brand can be a smarter long-term investment.
