Wall system
The wall-mounted air conditioning system is one of the most accessible devices on the market. It allows you to transform hot air into cold air when the temperature is excessively hot.
Composed of two units, one indoor and one outdoor, this system also dehumidifies the air through its filtration system. To optimize its performance and take advantage of all its benefits, it is advisable to call upon an expert such as Les Entreprises P. Theoret for its installation, maintenance, or repair.

Central system
A central air conditioning system draws warm air from inside and exhausts it outside. It distributes cool air more evenly than other systems. It is also the most environmentally efficient solution.
Whether it's for installation or repair, it's wise to call on professionals like us. Performing maintenance at least once a year is recommended and we can help you with that!

Heat pump, a 2-in-1 solution
A heat pump is the ideal solution if you are looking for a system that can both cool and heat your building. This type of unit works by using a compressor to circulate condensed or evaporated refrigerant between coils. It is this system that allows air to circulate between the interior and exterior of the building.
