Purchasing a bigger air conditioner will not necessarily improve your comfort during the heat. Actually, when an air conditioner is too large for the area it needs to cool, it is less effective and efficient than a properly sized air conditioner. The reason is that an oversized air conditioner will reach the thermostat’s set point before it can properly dehumidify the area. This makes the room feel uncomfortable and humid. You need a trained professional to size your air conditioning unit.
If your home has a central air conditioning system, make sure the fan shuts off simultaneously with the compression. This is typically done by setting the fan to “auto.” Do not use the central system’s fan to circulate air. This job is best accomplished by adding fans to individual rooms to improve air circulation http://air-conditioning-toronto.ca.
Consider adding a whole-house fan instead of using the air conditioning. A whole-house fan is useful in various climates and can cool your home by circulating cooler air throughout the house and allowing warm air to leave through the attic. The fan is most effective at cooling down your home by using it during the cooler times of day. Your home will remain cooler throughout the hotter times of day without the fan being used.
Tips for Cooling:
- In the summer, set your thermostat to a higher temperature and ensure your humidity controls are working. Your cooling bills will be lower when there is a smaller difference between the outdoor and indoor temperatures.
- Avoid turning your thermostat to an abnormally low setting when you turn on your system. The lower setting will not cool your home faster and may result in excessive cooling. This also makes your utility bills unnecessarily expensive.
- Add an interior fan to use in conjunction with a window air conditioner to help spread the cooler air throughout your home. Using a fan does not cause a significant increase in energy use and can help cool the space more effectively.
- Do not place appliances that generate heat near your thermostat. This can include televisions and lamps.
Tips for Long-Term Savings
- Consider replacing your old air conditioner with an energy efficient one. Look for models labeled with ENERGY STAR® and EnergyGuide. Room air conditioners with energy-efficient qualifications are 10% more efficient, while the qualified central systems are more efficient by 15% vs a standard system.
- Depending on your climate, you might also want to install an evaporator cooler or whole-house fan.
