Air conditioning vs heat pump in France: which do you need, and what grants apply in 2026?

In France you will hear both “climatisation” and “pompe à chaleur”. They are closely related, and the difference matters for your comfort, your bills and the grants you can get.

Air conditioning vs heat pump: what’s the difference?

• Air conditioning (climatisation) moves heat out of your home to cool it down.
• A reversible air-to-air heat pump (PAC air/air) is essentially the same equipment working in both directions: it cools in summer and heats in winter. Most modern split “air con” systems sold today are in fact reversible.
• An air-to-water heat pump (PAC air/eau) heats water for your radiators or underfloor heating (and often your hot water). It replaces a gas or oil boiler and usually does not cool.

Which one is right for you?

• You mainly want to be cool in summer, in an apartment with electric heating or collective heating: a reversible air-to-air system is usually the best fit.
• You want to replace an old gas or oil boiler in a house with radiators: an air-to-water heat pump is usually the right choice.
• You want both comfort and lower winter bills in a home with electric radiators: a reversible air-to-air system can heat far more efficiently than old convectors.

Grants and help in 2026

This is where the choice really matters:

• MaPrimeRénov’ (the main state grant) does not cover air-to-air heat pumps or air conditioning. It does cover air-to-water heat pumps, for owners in the eligible income brackets, with amounts that depend on household income. Since 1 September 2026, the scheme focuses on low-carbon heating, and the highest-income bracket is not eligible for heat pump funding.
• CEE energy-saving bonuses (primes énergie), paid by energy suppliers, can apply to both air-to-air and air-to-water heat pumps if the equipment meets efficiency requirements. Amounts vary with income and the supplier’s offer.
• Reduced VAT: works in homes over two years old usually benefit from a reduced VAT rate instead of 20%, with the lowest rate (5.5%) reserved for qualifying energy-efficiency works such as air-to-water heat pumps.

Two conditions catch many people out: grants generally require an RGE-certified installer, and the grant application must usually be made before you sign the quote. Sign first and you may lose the grant.
