Services

Our services

Design, installation, repair and maintenance of heating, air conditioning, ventilation and refrigeration, for homeowners as well as businesses.

Feasibility study

Before any installation, we survey your building: heating, air conditioning and ventilation needs, for residential, commercial and industrial sites alike. An accurate survey avoids nasty surprises: an oversized unit wastes energy, and an undersized one keeps breaking down.

  • Sizing and panel layout for solar PV
  • Several studies to compare before you decide
  • Correcting a poorly done study

Installation

Once the study is approved, we order the equipment from a supplier and install it. Equipment costs money, but over time it pays for itself in energy you no longer buy.

  • New installation
  • Extension of an existing system
  • Modification or full replacement, even of a very old system
  • Hybrid system that combines solar and electricity

Repairs

We arrive in a van stocked with what's needed. Minor faults are fixed during the visit. For a bigger fault, we order the part from our suppliers and come back to replace it.

  • On-site diagnosis, with a written quote
  • Same-visit repair when the part is in the van
  • Part ordered, old part removed, new part fitted

Maintenance

Anything that moves needs servicing. We check that settings haven't changed after a power cut and that the system still delivers its expected efficiency, whether or not we installed the equipment.

  • Preventive: a full check-up and an activity report
  • Corrective: repairs identified during the visit
  • Routine: regular visits and a maintenance contract

Our fields

What we install and maintain

  • Heat pumps

    Older models and the latest generation, using air, water or ground.

  • Solar panels

    Surveys, layout and installation.

  • Condensing gas heating

    Installation and maintenance of modern gas boilers.

  • Air conditioning and ventilation

    Cooling, heating and refreshing the air in homes and offices.

  • Cold rooms

    Small, medium and large, at positive or negative temperatures.

  • Underfloor heating and cooling

    A floor that cools in summer and heats in winter.

  • Plumbing for heat pumps

    Not basic plumbing: the hydraulics heat pumps need.

  • Water system treatment

    Chemical treatment of heating circuits in homes and boiler rooms.

  • General electrical work

    The electrical side of our installations, and beyond.

Refrigerants: fully tracked

Refrigerants harm the greenhouse effect, so the State requires proof. When we detect a leak, we record where it was, repair it, return the unit to service and state how much gas was lost. Recovered gas goes for destruction, and the record is sent to the relevant authority. Every visit ends with a service record that includes this leak-tightness record.

New equipment only

We neither sell nor recommend second-hand equipment. No one can guarantee 15 years for a unit that has suffered electrical surges, power cuts or misuse, and handling refrigerant fluids requires certification.

All brands, through our partner suppliers

Mitsubishi, Daikin, Toshiba, Atlantic, Hitachi and others. We order from suppliers where we have an account, and directly from the manufacturers who train us.

    Boiler · Repair

    « J'ai été très impressionné par le soin apporté à la recherche et à la réparation de la source de notre fuite de fioul, ainsi qu'à l'entretien de la chaudière. Il est resté jusqu'à tard dans la journée, prenant beaucoup plus de temps que les deux heures qu'il avait estimées pour le travail, mais sans frais supplémentaires. (Ce serait 5 étoiles s'il nous avait prévenus plus tôt, la veille, lorsqu'il avait prévu de venir, qu'il avait été inévitablement retardé.) »
