1-Air Conditioner size
Many factors are involved when determining what size of an air conditioner would have the required power output to cool or heat your home. These factors include the extent of exposure to the sun and the outside air, the thickness, and type of outside wall insulation, the size of the house, type and number of windows and outside doors, the ceiling height, the age of the house construction etc. Choosing the correctly sized of air conditioner is very important to cool or warm your house properly. An air conditioner or furnace unit that’s too small won’t cool or warm your house properly, and a unit that’s too big will cost more than necessary. If you live in Southern Ontario, you may use the charts beside to estimate the correct size of the heating or cooling product that you may need for your home.

2-SEER Values
Seasonal Energy Efficiency Ratio (SEER) is a cooling efficiency rating for air conditioners. The higher the SEER, the less electricity your air conditioner needs to cool your home. Higher SEER numbers indicate higher efficiency. The minimum SEER rating is 13 and the maximum is 21 SEER.
3-Installation distance/location
Before buying an Air Conditioner, consider where the outdoor unit will be placed. It is really important to talk with an HVAC technician to discuss the location where the unit will be placed. The heating & cooling professional will be able to give you the best option in terms of location and performance. The unit location will influence in the unit performance, the longer the distance between the indoor and the outdoor unit, the lower the performance of the system. Another factor to be considered is the distance between the wall and the outdoor unit, this distance must be enough to allow the air flow easily. Also, don’t forget to check the city bylaws, each city has theirs owns regulations about Air Conditioner placement. In the end, the location where the AC unit will be placed is the homeowners choice, but an expert HVAC technician could help them to make a better choice.
