In summer, high relative humidity, elevated air temperatures and bright sunshine can sometimes combine to produce an uncomfortable indoor environment. An air conditioning system can provide comfort for occupants by lowering the air temperature and the humidity level in the home. Options that are open to the consumer include a room air conditioner, a central air conditioner or a heat pump. The best choice of system will depend on your circumstances therefore, it is worthwhile taking the time to evaluate your needs. Does the whole house need to be air conditioned or would cooling in one or two rooms be sufficient Room air conditioners offer an effective, low cost approach to providing comfort in a small space, up to three rooms, with minimum installation effort. Central air conditioners and heat pumps are used to cool the entire space. Central air conditioners are cooling only products, whereas heat pumps provide winter heating as well. The cost of a heat pump is greater than that of a central air conditioner, which is greater than that of a room air conditioner. The choice between central air conditioners and heat pumps is examined in Natural Resources Canadas booklet Heating and Cooling With a Heat Pump. If you are currently renting your home or apartment or if you are planning to move in the near future, a significant investment in either a central air conditioning system or a heat pump probably does not make sense.

However, a room air conditioner can be moved with you and re installed in another residence. If your home has a central air duct system and an acceptable place to mount the outdoor unit, installation of a central air conditioner or heat pump should be straightforward. In bungalows with unfinished basements, the addition off a duct system may be relatively simple and inexpensive, but in other cases, this option is usually expensive and frequently impractical. In these cases, there are two other options for central systems Mini split units that distribute cooling by using two or three indoor sections connected to a single outdoor unit. Central air conditioning systems that use small diameter high pressure ducts, designed to facilitate retrofit installation through walls, floors and attic spaces. There are a number of things that you can do to reduce the need for mechanical cooling in your home, thereby minimizing the capacity and cost of the equipment that you purchase and the amount of electricity that it will consume. Actions you can take to reduce cooling requirements are as follows Caulk and weatherstrip to seal air gaps, and ensure that the attic and exterior walls are insulated to meet or exceed the minimum recommended levels to minimize heat transfer to the interior. Use awnings, blinds or drapes to keep direct sunlight from entering the living space. Deciduous trees planted on the south and west sides of the house and wide roof overhangs will reduce solar heat gain to the interior in summer, while having only a small effect on heating in winter. Light coloured exterior finishes will also help reduce solar heat gain year round. Turn on the kitchen rangehood fan when cooking, if it exhausts outside, and turn on the bathroom fan while bathing to minimize moisture buildup in the space. Select the right pipe size every time. The Refrigerant Piping Design program determines the minimum pipe size required to deliver refrigerant between the compressor. Turn off lights and appliances that are not needed. Plan heat and moisture generating activities cooking, dish washing, drying clothes and bathing for cooler morning and evening hours. Consider using appliances with time delay controls. In addition to generating heat and humidity at a less noticeable time after midnight, for example, your air conditioner will operate more efficiently in the cooler night hours. Select compact fluorescent lamps and energy efficient appliances, since they produce less waste heat than conventional products. The electricity consumed by a less efficient refrigerator, for example, is converted to heat, which is released into your kitchen. There are several common heat sources in a house. Becoming informed about all aspects of air conditioning your home is the way to ensure that the correct choices are made for your particular cooling needs. This booklet identifies the commonly available air conditioning equipment and discusses factors involved in selecting, installing, operating and maintaining an air conditioning system. It provides you with a sound basis for making a smart purchasing decision. Types of Air Conditioners. As mentioned previously, there are two basic types of air conditioners room air conditioners and central air conditioners. However, there are several different kinds within each type. Variations of room air conditioners are as follows Window mounted types are available for installation in single and double hung windows, as well as for horizontal sliding windows and even casement windows. Wall mounted units use a sleeve to allow for through the wall mounting instead of window mounting. Free standing portable units are easily moved on casters some require temporary ducting to the outdoors. Variations of central air conditioners are as follows A single package unit contains all the components and generally mounts through the wall or on the roof. Introduction Is the air coming from the vents in your car just not as cold as it used to be Youve likely run low on refrigerant in your AC system. Over time. Installing a Refrigerant Dryer Filter Unit on the Air Conditioning or Heat Pump Refrigerant Line. Once an air conditioner or heat pump system refrigerant leak has.

Ducting to and from the unit conveys air to and from the rooms. This type is not commonly used in residential applications. A split system unit consists of indoor and outdoor sections. The indoor heat exchanger, or coil, mounts above the furnace, inside the ducting. The outdoor section consists of the remaining components, and the two sections are joined by refrigerant lines connecting the indoor coil to the refrigeration components in the outdoor section. A mini split unit is similar to a split system but contains more than one indoor coil connected to one outdoor unit. Some mini split units have as many as three indoor units. These units are ideal for homes with new additions, as there is no need for ductwork. The indoor section simply mounts on an inside wall, the ceiling or the floor. The outdoor and indoor units generally have a very slim profile compared to conventional split systems. The efficiency of mini split units tends to be lower than other split systems, which needs to be taken into account when considering such a unit. A mini duct unit is a central air conditioner where the indoor section is installed in the attic, and air is distributed through plastic pipes in partition walls to outlets and inlets. These units can be retrofitted in homes with electric or hydronic baseboard heating that have no ductwork. Finally, water cooled residential air conditioners can be connected to city or well water. Check with local authorities to determine if water cooled equipment is permitted. These types are seldom used in Canadian applications, even if permitted, because operating costs would include electricity, as well as water and sewer charges. The remaining sections provide more information on the two basic types of air conditioners. Coming to Terms with Air Conditioners. Here are some common terms you will come across when comparing and determining the best choice for air conditioners.
