What is a reversible air conditioning unit?
+
A reversible air conditioning unit (or air-to-air heat pump) reverses its cycle to cool in summer and heat in the shoulder seasons. It effectively replaces a direct electric heater while providing excellent summer comfort. The heating efficiency (COP) remains above 4 in the majority of cases.
How much does air conditioning installation cost?
+
For a single-zone wall-mounted split (one room), budget between 3,500 and 5,500 CHF all-in. For a multi-zone system (3 to 5 rooms), between 9,000 and 14,500 CHF depending on brand and technology. The quote is prepared after a technical visit.
Is a permit required to install air conditioning?
+
In Western Switzerland, installing an outdoor unit may require a declaration or permit depending on the municipality and co-ownership. I.ON handles all administrative steps. For buildings in co-ownership (PPE), the approval of the owners' assembly is generally required before installation.
What is the lifespan of an air conditioning unit?
+
The Daikin, Mitsubishi and Panasonic units we install have a typical lifespan of 12 to 20 years with regular maintenance. The manufacturer warranty is 5 years, extended to 10 years on certain premium references.
Does air conditioning consume a lot of electricity?
+
Modern models (class A+++ or SEER ≥ 8) consume three to five times less than an old unit. Coupled to your solar installation, summer consumption can be almost entirely covered by your solar production — at the moment it is highest.
What noise level does the outdoor unit produce?
+
Modern Daikin, Mitsubishi, Panasonic units produce 40 to 50 dB(A) at 1 metre, equivalent to a library. With careful placement (at least 3 metres from neighbouring windows, appropriate orientation), Swiss noise protection (OPB) standards are met without difficulty in residential areas.
Can air conditioning heat the whole house in winter?
+
Technically yes, but it is rarely the right choice in the Swiss climate. The COP drops in severe cold and air distribution from a split is less uniform than underfloor heating. For primary heating, an air-to-water heat pump remains preferable. Reversible air conditioning is ideal as a supplement or for shoulder seasons.
Is annual maintenance necessary?
+
Recommended to preserve the warranty and performance. Budget 200 to 350 CHF/year for a single-split, 350 to 600 CHF for a multi-zone. Maintenance includes filter cleaning, refrigerant pressure check and electrical connection inspection.
Are refrigerants environmentally friendly?
+
Units installed since 2024 use R32, whose global warming potential is three times lower than the previous R410A. Future European regulations will push towards R290 (propane) with very low impact, already available on certain premium references.
