The heat wave is coming, we already feel it in Montreal and everywhere in Quebec. You probably feel it’s time to get a good wall air conditioner. Here are 3 important points to consider before purchasing one, once you have decided on your budget.
1 – THE POWER OF YOUR AIR CONDITIONER
First, calculate your cooling needs to choose the unit with maximum power, measured in BTU/hour (British Thermal Units).
An air conditioner that is too powerful will evacuate the heat of the house too fast and it will wear out more quickly. An air conditioner that is not powerful enough will work non stop without maintaining a comfortable temperature and will cost you a fortune in electricity.
Here is a table that can guide you:
POWER OF THE DEVICE AREA TO CLIMATE
9,000 to 12,000 BTU/hr Up to 10,000 sq.ft.
14,000 to 18,000 BTU/hr 1,000 to 1,5000 sq.ft.
24,000 to 36,000 BTU/hr 1,500 to 2,5000 sq.ft.
Discuss this with the representative who will take into account the layout of your home, the windows, the level of sunshine and insulation to give you the best advice on the ideal device for your needs.
2 – ENERGY EFFICIENCY
To make an eco-responsible and economical choice, Natural Resources Canada offers 2 energy efficiency codes that you will find in bold on the EnerGuide label of the model:
- a) Seasonal Energy Efficiency Ratio (SEER)
b) The Energy Efficiency Ratio (EER)
The higher these rates, the more energy efficient the unit is. SEER ratings range from 13 (the least effective) to 30 (rare on the market) and those of the EER range from 8 (minimum efficiency) to 14 (maximum effectiveness).
With a SEER of 14.5 and a EER of 12, a device will receive the EnergyStar rating. That means you could save between 30% and 40% on your electricity bill compared to models from 10 or 15 years ago. In addition, you can be proud to have made an eco-friendly choice!
3 – SPECIAL CHARACTERISTICS
Make a list of special features you want for your wall-mounted air conditioner. Whether it’s a low noise level, a timer, an automated shutdown system or a dehumidification option, you’ll save shopping time knowing exactly what you want.
TWO BONUS TIPS
1) Experts agree that a good quality device has a life of 12 to 15 years. By checking the duration of warranty of the device, you will have a reliable index of its quality. Do not forget to ask for a detailed copy of the warranty, covering important information such as parts and labor.
2) The installation of the unit is essential, so deal with industry professionals to make sure that your wall mounted air conditioner is installed to the standards and that it is waterproof and safe. And you also plan for regular maintenance on your unit.
