Heat pump installation on the Cote d'Azur, with English-speaking specialists
Nearly every heat pump fitted in a Riviera home is reversible: the same unit heats in January and cools in August. What trips up English-speaking owners is the rest: knowing which subsidy applies to which unit, and getting the full quote in writing.

Sizing and siting: what to settle with your heat pump installer
Two decisions shape how well a heat pump runs: how big it is, and where the outdoor unit goes.
The size should come from a heat loss calculation. Many Riviera houses are old stone buildings with patchy insulation, so a guess from floor area is usually wrong. An oversized unit keeps switching on and off, which wears it out early and pushes up the bills. Ask how they worked out the size. If the answer is floor area alone, get another quote.
The outdoor unit needs space for air to flow and shouldn't blow at a neighbour's terrace. Some communes set rules on noise and distance from the boundary, so ask the installer to check yours.

Climate and efficiency
Why do heat pumps work particularly well in the Mediterranean climate?
A heat pump pulls warmth out of the outside air, and the milder the air, the less work it does. The average January temperature in Nice is 8-10°C, far warmer than northern Europe.
Through the coldest months on the coast, a well-specified unit gives about 3.5 to 4 kWh of heat for every kWh of electricity it uses. Installers call that ratio the COP. A plug-in electric heater gives 1. The backup heater that Scottish or Swedish heat pumps rely on may never switch on here.
Inland is different. Grasse sits at 350m and villages like Gourdon at 500m or more, with frost and nights of -2°C to -5°C. If you live inland, ask whether the installer allowed for the altitude. They may suggest a slightly larger unit or a backup element.
System types
Which types of heat pump are available on the Côte d'Azur?
Most common
Reversible air-air split
An outdoor unit feeds one or more indoor units that blow warm or cool air into the room. Most Riviera apartments and villas end up with this. For a whole house on one outdoor unit, see our multi-split page.
Air-to-water (PAC air-eau)
Heats the water in radiators or underfloor heating, and usually replaces a gas or oil boiler. Small old radiators may need replacing.
Ground-source heat pump
Draws heat from pipes buried in the garden or from a borehole. On the coast it's only slightly more efficient than air-source and costs much more. It also needs land for the pipes, so suits larger plots.
Heating and cooling in one unit
Why is almost every heat pump on the Côte d'Azur reversible?
Because both seasons need it: mild winters, then 30-35°C in July and August. A valve that reverses the cycle lets one machine do both, and it costs little next to a second system.
Sized only for winter, a unit struggles on a still August afternoon. Sized for August, it's too big for winter and switches on and off all season. Ask whether the installer worked out the heating need and the cooling need as two separate figures, and chose a unit that meets both.
Before you read a devis, know that every subsidy is assessed on the heating side. The cooling never earns anything extra.

How much does heat pump installation cost on the Côte d'Azur?
These are pre-subsidy prices for installed systems in the Alpes-Maritimes and Var, including equipment, labour and basic electrical work. Major pipework changes and a new fuse board (tableau) are extra. Our heat pump cost breakdown gives figures by property size.
Figures are guidelines. Installation costs vary and subsidy rates change quarterly.
Confirm current amounts with your installer before signing.
Financial aid
What subsidies are available for heat pump installation in France?
Three schemes can apply: MaPrimeRénov', CEE credits and reduced TVA. Which ones you get depends on the type of heat pump. That's the misunderstanding we see most often.
MaPrimeRénov' does not cover a standalone PAC air-air installation, and hasn't since January 2025. Since most reversible splits on the Riviera are air-air, do not put MaPrimeRénov' in your budget for one.
MaPrimeRénov' is the government's main renovation grant, and the amount depends on household income. It covers air-to-water and ground-source heat pumps in your principal residence only, so a holiday home doesn't qualify. An air-air split can only be included inside a rénovation d'ampleur, a whole-house project that starts with an energy audit. Register at france-renov.gouv.fr before any work starts.
CEE (Certificats d'Economies d'Energie) are paid for by energy suppliers and are the main help for a reversible split. There's no income test or residence rule, and the installer arranges them. On the Côte d'Azur they come to only about 220-350 EUR for an air-air unit, because the coast is in the lowest-paying climate zone. The unit must also meet an efficiency threshold, so ask the installer to confirm it does. On air-to-water or ground-source, CEE comes on top of MaPrimeRénov'.
TVA réduite at 5.5% has applied to air-to-water heat pumps for years, against 10% for other work on a home over two years old. On a 12,000 EUR installation (the price with TVA at 10%) the gap is about 490 EUR. Air-air units have qualified only since 18 July 2026, and only if they meet an efficiency and connectivity spec. A cheaper split that misses it stays at 20% on the equipment and 10% on the labour, so check the rate on the devis. Our MaPrimeRénov' guide covers the application in full.
Coming from abroad
What's different about buying a heat pump in France?
UK
There's no Gas Safe equivalent: look for RGE, specifically the QualiPAC label. A UK heat pump only heats, so the cooling half of a quote here tends to get waved through. Check it as closely as the heating. The Boiler Upgrade Scheme doesn't apply, and MaPrimeRénov' won't cover the air-air split most people fit.
US
French installers size in kW, not BTU, so their figures will look different from an American quote. That doesn't mean the system is too small. American equipment won't run on French mains.
Germany
MaPrimeRénov' is the nearest thing to a BAFA grant, but the amount is set by your household income band. CEE credits have no German equivalent. The devis, a written quote before work starts, will feel familiar.
Choosing a contractor
What to look for in a heat pump installer on the Cote d'Azur
RGE certification for heat pumps. Ask for the QualiPAC certificate or an equivalent and check the expiry date, or look them up at the France Rénov' RGE directory. A certificate for solar or insulation doesn't cover heat pumps.
Local references for homes like yours. Twenty installations in Antibes apartments don't make a contractor right for a 300m2 stone bastide in the Grasse hills. Ask about your property type and altitude.
A full written devis before any work. It should name the make and model, the efficiency rating, the scope and exclusions, the parts and labour warranties, and any subsidy amounts. If a contractor won't write this down, move on.
Questions to ask: How did you size the system? Who services it after installation, and at what cost? Is the manufacturer warranty registered in my name?

Questions
Frequently asked questions about heat pumps on the Cote d'Azur
If your question isn't here, send it with your request and we'll answer it directly.
Most Riviera homes can take an air-source heat pump. On a site visit the installer should check where the outdoor unit can go, whether the electricity supply is big enough, and whether your radiators or underfloor heating suit it. Old high-temperature radiators may need replacing. An installer who sizes by floor area without visiting isn't doing the job properly.
Partly. MaPrimeRénov' is out, because it only pays for work on your principal residence. CEE credits have no residence rule, so a second home still gets them. Reduced TVA also applies to a second home, as long as it's over two years old and the unit qualifies. Ask the installer to show both on the devis.
A reversible heat pump is the same machine with a valve that lets it run backwards, so it cools in summer as well as heating in winter. Almost every split system sold on the Cote d'Azur is reversible. To be sure yours is, check that the manufacturer's spec sheet lists the model as réversible, not just the quote.
For most homes on the Cote d'Azur, yes. A reversible multi-split for a standard villa costs 4,000-8,500 EUR installed, with one set of equipment to service and one outdoor unit. If you have working gas or oil heating and only want cooling, a cooling-only split is simpler. Our reversible heat pump vs AC comparison covers where the line falls.
Yes, but it needs sizing for the altitude. Inland villages get frost and nights of -2°C to -5°C, which the coast almost never sees. Ask the installer whether they sized for your altitude. They may suggest a slightly larger unit or a backup element for the coldest nights.
It only covers air-to-water and ground-source systems in your principal residence. Get a devis from an RGE-certified installer, then register at france-renov.gouv.fr and wait for approval before any work starts. You can't claim for work already done. Once the job is finished, you submit the installer's invoice for payment.
