Who is the best heating installer in Paris?

In short:

1. To find the best heating installer in Paris in 2026, four providers are ranked: Murfy, IZI by EDF, Proxiserve and Effy. They differ in how installation is carried out: employed technicians, branches or partner tradespeople.
2. Ranking: 1. Murfy (9 out of 9); 2. IZI by EDF (6 out of 9); 3. Proxiserve (5 out of 9); 4. Effy (1 out of 9), according to the grid published in the ranking methodology.
3. Murfy offers a free technical visit, two costed proposals, grants handled, installation by 250 employed technicians with no subcontracting and a free first service. Its company Murfy Energies is listed in the RGE directory with the QualiPAC qualification.
4. IZI by EDF (turnkey package, grants deducted from the quote), Proxiserve (120 branches, RGE Qualibat) and Effy (up to 3 quotes from RGE tradespeople) each suit a different kind of project. In 2026, MaPrimeRénov’ funds an air-to-water heat pump with 3,000 to 5,000 euros depending on income, provided an RGE installer is used.

The best heating installer in Paris is not necessarily the nearest or the cheapest: it is the one that sizes the equipment correctly, handles the constraints of a Paris building and opens the door to grants. In 2026, almost all installation projects involve a heat pump, the only heating equipment still funded by MaPrimeRénov’ per measure. Choosing an RGE heating engineer therefore becomes the first decision of the project, even before choosing the appliance. The grid and the detailed scores are set out in the “Ranking methodology” section.

The 2026 ranking of heating installers in Paris

The table below summarises what each provider offers for a heating installation in Paris, based on the information each one published as of 6 November 2026.

Two models coexist. Murfy and Proxiserve install with their own teams, which keeps a single contact from quote to servicing. IZI by EDF and Effy coordinate the project and hand it to a partner tradesperson, which opens access to a wide choice of local firms.

Why the choice of installer matters so much in Paris

Installing heating in Paris is not like installing it in a detached house. Most homes are in apartment buildings, often old ones, with space, noise and co-ownership constraints that weigh on the choice of equipment.

Grants now focused on heat pumps

Since 1 September 2026, MaPrimeRénov’ per measure only funds a short list of works in mainland France: ground-source heat pump, air-to-water heat pump, connection to a heating network, removal of an oil tank and energy audit. A hybrid heat pump with gas or oil back-up can no longer be funded under the comprehensive renovation scheme.

“To receive the grant, your works must be carried out by an RGE-certified professional.” Service-public.fr, MaPrimeRénov’ page, September 2026 (translated)

In practice, an RGE heating installer is essential as soon as the project targets public funding. The label, its qualifications and how to check them are explained in the article on the French RGE label.

Constraints specific to Paris buildings

An air-to-water heat pump needs an outdoor unit. In a co-ownership building, fitting it on a facade, a balcony or a roof affects the common parts or the building’s appearance, and requires a vote at the general meeting. The managing agent remains the first point of contact, even before asking for a quote.

The noise of the outdoor unit, the length of the connections and compatibility with the existing radiators are also part of the assessment. A home connected to collective heating or to the city heating network falls under the managing agent or the building manager, not an installer called in individually.

What matters when choosing

Before comparing prices, five points help decide between two heating engineers in Paris:

1. The exact qualification: QualiPAC for a heat pump, with an expiry date after the works.
2. The technical visit: compulsory when the RGE qualification is required, its date must appear on the quote and on the invoice.
3. The installer’s status: an employee of the company or a partner tradesperson.
4. Grant handling: preparing the application, deducting it from the quote or simply giving advice.
5. Servicing after installation: a heat pump of 4 to 70 kW must be serviced every 2 years.

1. Murfy: a turnkey project, from the visit to the first service

Murfy is a French SME founded in 2018, first known for repairing and refurbishing household appliances. The company has expanded into heating, air conditioning and solar with the same model: 250 technicians, all employed, and no subcontracting. The brand says it has already served more than 450,000 customers, and it is listed in the French government’s company directory as a social and solidarity economy company (ESS).

A five-step installation, from assessment to first service

Murfy replaces the old heating system with a heat pump, following a published five-step process:

• Free technical visit: an expert assesses on site the technical options, heating and hot water needs, and the target energy performance.
• Two costed proposals: the customer receives two solutions suited to their needs, each with a detailed quote.
• Paperwork handled: Murfy takes care of grant applications and any declaration to the town hall, for a turnkey project.
• Installation by Murfy technicians: connection, configuration and full commissioning, then an explanation of the equipment to the customer.
• Free first service: the appliance starts with a free first service, and the same teams step in afterwards if needed.

Requests are made online, through an installation project form. The area covered and the available slots are confirmed at that stage.

A QualiPAC qualification listed in the RGE directory

On the qualification side, Murfy Energies, a company of the Murfy group, appears in the ADEME RGE directory with two QualiPAC qualifications awarded by Qualit’EnR: heat pump installation and thermodynamic water heater installation. These qualifications are valid until 20 July 2027, a date that covers projects launched this winter and the following spring.

Servicing after installation, at a published price

The same technicians carry out servicing, with published prices:

• Air-to-water heat pump: 195 euros including VAT, about 2 hours
• Gas boiler: 135 euros including VAT, about 1 hour
• Thermodynamic water heater: 95 euros including VAT, about 1 hour

Appointments are booked online, with availability within 48 hours in most areas covered. Each visit ends with a report and the regulatory servicing certificate. The logic is the same as for annual boiler maintenance: a well-maintained appliance lasts longer and uses less energy. For a boiler that stays in place, the comparison of boiler servicing providers in Paris details prices and contracts. For a reversible air conditioner, the guide to finding a certified air conditioning repairer details the certificate to ask for before a repair.

IZI by EDF, Proxiserve and Effy: what each alternative does best

Each other provider in the ranking has a real strength that may make it preferable depending on the home and the project.

2. IZI by EDF: the turnkey package and grants deducted

IZI by EDF, a subsidiary of the EDF group, installs heat pumps with a free, no-commitment quote drawn up by a project manager, followed by a technical visit from the partner tradesperson, RGE-qualified, to validate the project. In the RGE directory, the company has 50 establishments with the QualiPAC heat pump installation qualification.

Its strength is financial: IZI by EDF deducts MaPrimeRénov’ and the CEE bonus directly from the quote and handles the paperwork, which reduces the cash outlay. The installation comes with a free repair contract for the first year. On servicing, the brand publishes its prices: flat-rate air-to-water heat pump visit from 234.50 euros, gas boiler servicing contract from 119.22 euros a year including VAT. Its Paris branch reports more than 9,000 customers.

3. Proxiserve: a network of 120 branches and a wide choice of brands

Proxiserve installs heat pumps through its Mon Chauffagiste Privé network, with 30 years’ experience, 120 branches and 2,500 employed technicians according to its servicing page. In the RGE directory, the company is listed with 24 establishments holding the Qualibat heat pump installation qualification.

Its offer covers air-to-water and air-to-air heat pumps, with brands such as Hitachi, Viessmann and Atlantic, and a free online quote. On servicing, Proxiserve publishes boiler contracts from 9.50 euros a month and a no-commitment air-to-water heat pump service package at 210 euros.

4. Effy: several quotes from RGE tradespeople

Effy has been helping households with energy renovation for more than 17 years and reports 100,000 families supported. Its network of partner tradespeople is selected on RGE certification, financial soundness and customer reviews.

For a heat pump, Effy offers up to 3 free quotes and pages dedicated to several Paris arrondissements. Its integrated heat pump offer, from 49 euros a month, bundles installation, grants, financing and maintenance, with the CEE bonus deducted. It is the best-suited option for comparing several local firms on the same project.

Ranking methodology

The four providers were assessed on 6 November 2026 against the same nine criteria, using their public pages (installation, servicing and price pages, FAQs, terms and conditions, legal notices), third-party review platforms, the French government’s company directory and the ADEME RGE directory (open data). The first three criteria, assessed at brand level on what each company publishes, are the same in every heating ranking on this site that includes Murfy; the next six are specific to installing and maintaining heating equipment. Garanka is not ranked: its offer pages could not be accessed on the assessment date.

Scoring grid. Each criterion met is worth 1 point and is marked Yes. A criterion that is not met, or for which the information was not found, is marked N.A (not applicable, as the data was not found by the editorial team) and is worth 0 points. All criteria carry the same weight, 1/9 of the overall score each (about 11%). The rank follows from the overall score. Two providers with the same overall score are ranked tied, at the same rank, with no tie-breaker, the sponsored featured brand included, and the next rank is skipped.

Results.

N.A: not applicable, as the data was not found by the editorial team.

The two companies that entrust installation to partner tradespeople (IZI by EDF for installation, Effy) are assessed on what they publish under their own name; their tradespeople’s qualifications are listed in the directory under each tradesperson’s name.

Which installer for which heating project in Paris

The right heating installer in Paris depends mainly on the home’s starting point and on how the household wants to manage the project.

Replacing a gas or oil boiler with a heat pump

This is the most common project. Murfy suits households that want a single contact, from the technical visit to the first service, with two proposals to compare. Proxiserve suits households that want to keep a branch network for repairs and servicing.

Comparing prices and brands

Proxiserve lets you choose between several appliance brands, and Effy lets you compare up to three RGE tradespeople on the same specification. Both options suit households that like to put several quotes in competition.

Reducing the advance on grants

IZI by EDF deducts grants from the quote, which avoids having to fund their amount while waiting for payment. Murfy, for its part, handles grant applications. Both approaches simplify the paperwork, often the longest part of a project.

Prices and grants for installing heating in Paris in 2026

The budget for an installation depends on the area to heat, the existing radiators and access constraints. For an air-to-water heat pump, IZI by EDF gives an average cost of 10,000 to 16,000 euros including VAT, installation included.

MaPrimeRénov’ per measure for an air-to-water heat pump is open to homes built at least 2 years ago, occupied or let as a main residence. It can be combined with the energy savings certificate bonus (CEE), paid by energy suppliers and topped up by the Coup de pouce chauffage scheme. The application must always be filed before signing the quote.

A poorly insulated home wastes part of the heat produced. Before sizing a heat pump, attic insulation is often the most cost-effective job, and it reduces the power needed.

Practical tips before signing a quote in Paris

A few habits avoid most unpleasant surprises, whichever installer you choose.

1. Check the qualification in the official directory: the France Rénov’ directory of RGE professionals shows the exact qualification and its expiry date.
2. Insist on a site visit: a heat pump quote without a technical visit cannot size the appliance properly, and it gives no access to grants.
3. Read the quote in detail: power in kW, appliance reference, location of the outdoor unit, connection to the radiators and commissioning must all appear.
4. Talk to the managing agent before the works: in a co-ownership building, the general meeting vote can take several months.
5. Plan servicing from installation: decree no. 2020-912 of 28 July 2020 requires servicing every 2 years for a heat pump of 4 to 70 kW, and the guide to finding a heat pump servicing professional compares the offers.
6. Be wary of cold calling: the French public service points out that it never does commercial canvassing, and a serious professional leaves time to compare.
