What kind of air conditioner should we buy?

We are a family with young children in a residential apartment. What system should we install?

In this case, where the house is fully occupied, the recommendation is for a mini-central unit that will air condition the entire house. The price is reasonable, a uniform temperature will be obtained throughout the house and its operation will meet the requirements.

We are a family with older children who are not always at home (son is in boarding school, daughter in college, etc.). What system should we install?

In this case, where the house is not fully occupied, it should be divided into several units based on your daily living space, for example: install a small split unit in your bedroom in addition to a mini-central unit for the rest of the house. The air conditioner will accommodate you in your room, most of the time, and the mini will be activated when the house is fully occupied, thus you will consistently save on electricity (in such case, you must verify that there is room for to external condensation units).

We are an affluent family with young children, constructing a private home. What system should we install?

There are several alternatives:

A. A split air conditioning unit in your bedroom and mini-central units in the other areas (children’s rooms, living room, basement).
B. Air conditioning unit with variant refrigerant flow –You will save on the cost of connecting to the electricity and on ongoing electricity expenses, which will return the expense within 5-6 years (compared to the difference between this and a mini-central system).

We are a middle class family with older children who are not always at home constructing a private home. What system should we install?

Seeing that you do not require full output capacity and assuming there is enough room on the roof, you should install a split air conditioning unit in each room, for each child, in addition to a mini-central unit for the large spaces, such as the living room and kitchen or basement. In doing so, you will save electricity and the air conditioning will operate only in the occupied spaces.

We are a rich family constructing an extravagant private home. Money is no object for us and we want the best and most sophisticated air conditioning system. What system should we install?

There are two alternatives for houses like these:

A. A set of chillers (Carrier, Trane, Clementoni, MTI or equivalent).
B. VRF (Variant Refrigerant Flow) system (Mitsubishi, Daikin or equivalent) The chiller system is cheaper to install and more expensive on ongoing upkeep (maintenance and electricity).
The VRF system is more expensive to install but significantly more economical with electric consumption and maintenance.
We recommend the VRF system. In this case, you should consult and plan the installation with a senior engineer, who will adjust the system to the unique architectural plan and coordinate it with all other systems (electricity, drainage, construction, acoustics, etc.).

We are a poor family and we do not have the money for air conditioning. What are the options available to us for relief from the heat?

The least expensive option is fans, but please not that ventilation is only effective when the air is blown directly onto the skin! Seeing that this process causes perspiration to evaporate, we recommend installing relatively low costing fans in your proximity.
Ventilation in which the air is not blown directly onto the body is ineffective!

We are broke newlyweds and we can’t even afford a fan. What are the options available to us for relief from the heat?

First, close all windows and blinds to prevent the penetration of sun to the apartment. Secondly, seeing that the floor temperature is several degrees lower than room temperature, take of your clothes and lay on sheets spread on the floor.
