As part of its Energy efficiency program, Joseph Élie offers a complete test of your heating equipment.       The technician goes to your home to carry out the test.       With the Combustion analyser unit, the Joseph Élie technician probes the furnace so as to evaluate the performance of the equipment.           Following the analysis of the heating equipment, the Joseph Élie Sales’ advisor communicates the results to the owner.     Illustrations : Kimi Kimoki
