Frequently asked questions (business)
Quick answers about our B2B services: commercial AC, maintenance, repairs and audits.
Do you only operate in Lille?
We cover Lille and the entire Lille metropolitan area. For multi-site businesses, we can plan interventions by zone and schedule to match your operational constraints.
Can you air-condition premises with no outdoor access?
Yes. When it is impossible to install an outdoor condenser (courtyard buildings, basements, back-of-shop units, enclosed plant rooms), water-cooled air conditioning is a suitable option. Heat is rejected through a water loop (building circuit, water chiller, adiabatic cooler or cooling tower depending on the site), without a conventional facade-mounted outdoor unit. Hecker & Frères Énergie (HFE) carries out a technical site survey to confirm feasibility, size the system and recommend the most appropriate solution.
Do you offer maintenance contracts for businesses?
Yes. We provide preventive maintenance contracts (scheduled visits, checks, tuning) and priority repair options. The goal is to reduce breakdowns, secure performance and optimise energy consumption.
Can you handle urgent repairs?
Yes, depending on availability and criticality. We can set up an approach tailored to your needs (prioritisation, occasional on-call coverage, common spare parts) to minimise downtime.
Can you perform an energy audit before work starts?
Yes. We carry out a site visit and assess your needs (usage, occupancy, capacity, constraints). We then provide a clear proposal including solutions, sizing, budget and timeline.
