Frequently asked questions about air conditioning
What is the difference between standard and reversible air conditioning?
Standard air conditioning only cools, whereas reversible air conditioning can also heat by reversing its refrigeration cycle. This is known as an air-to-air heat pump. Efficiency (COP) is excellent: 3 to 4 kWh of heat delivered per 1 kWh consumed. It is the most cost-effective 2-in-1 solution for cooling and heating.
How much does reversible air conditioning cost in Lille?
For a standard single-split, expect between €1,800 and €3,500 incl. VAT installed. For a 3-indoor-unit multi-split, between €5,500 and €9,000 incl. VAT. A whole-house ducted installation starts around €9,500 incl. VAT. All our quotes are free, detailed and include a sizing study.
Is reversible air conditioning eligible for grants?
No. Reversible air conditioning (air-to-air heat pumps) is not eligible for MaPrimeRénov' or the CEE heating boost scheme. Budgets shown on our website are fully installed prices incl. VAT, with no government grants.
How can reversible air conditioning improve my EPC rating?
Installing an air-to-air heat pump (reversible air conditioning) can, based on our field experience, improve your property's energy rating — by up to three bands in the most favourable cases, for example after very inefficient direct electric heating. Results vary with building condition, insulation and unit sizing. Even without government grants, it remains a worthwhile way to add value to your home. We cover this during your free pre-quote study.
