For a larger villa of 100 m2 or more, it is usually best to go for a combination of Single-Zone, Twin-Zone, and possibly a Multi-Zone system. However, we do not recommend a large Multi-Zone system for the entire residence because you risk being completely without cooling/heating if, for any reason, the main unit of the system ceases to function. With several smaller systems, you also get greater flexibility to, for example, choose to run only the units that are needed at any given time. Regardless of the system chosen, an indoor unit is installed in each room, while the outdoor units are either mounted on the house facade, balcony, terrace, or directly on the ground, depending on what is possible and what provides the best conditions for the system to efficiently cool the residence during the hot summer and provide sufficient heating during the winter months (A shaded location allows the system to operate more efficiently and economically, while a sunny location makes the machine work harder, potentially leading to increased future service needs). Check what applies to your house before ordering your system. Sometimes, outdoor units must be placed on the roof of the house, and this may require some additional components to, for example, channel away condensation water, etc. Contact projects@mrchris.ac if you want us to help you with this. It's an additional service that we charge for per hour. For some, it's worth paying for this and avoiding worries about anything going wrong with the building permit. Simple and easy and convinient.
In our example, the outdoor units are placed on the balcony and on the facade as close to their respective indoor units as possible. The piping from the indoor units can then be drawn directly through the exterior wall to the outdoor units, which is the simplest and most cost-effective way to install an AC-Heat Pump. Also, note that we have chosen to have an indoor unit in the kitchen as well. If the residence had an open floor plan between the kitchen and living room, one indoor unit would have been sufficient.
When it comes to larger residences, we always recommend a home visit by our technician so that we can, together on-site, assess the conditions of your residence. However, for a townhouse or a larger villa, you should always consider at least 2 Single-Zone systems and 2 Twin-Zone systems. We always recommend investing in a quality machine from a well-known brand, preferably a model with a slightly higher capacity than strictly necessary. This way, with proper care, you will have a system that will last for many years. You will get a system that can easily provide a comfortable indoor climate regardless of the season and extreme temperature fluctuations.
