proper use of your home’s air conditioning system

• Understand the Air Conditioning System: Familiarize yourself with the type of air conditioning system in your home. It could be a central air system, window unit, or a split system. If you have an evaporative cooler (also called a swamp cooler) scroll down to the next section.
• Set the Thermostat Efficiently: Set the thermostat to a comfortable but energy-efficient temperature. For cooling, the U.S. Department of Energy recommends a setting of 78°F (26°C) when you’re at home and active, and higher when you’re away.
• Close Doors and Windows: Keep doors and windows closed while the air conditioning is running to prevent cool air from escaping and warm air from entering.
• Use Fans Strategically: Use ceiling fans or portable fans to circulate cool air more effectively. Fans create a wind-chill effect, allowing you to set the thermostat a bit higher while maintaining comfort.
• Replace or Clean Air Filters: If your home has a central air system, regularly replace or clean the air filters according to the manufacturer’s recommendations. Clean filters ensure optimal performance and air quality.
• Close Blinds or Curtains: Close blinds or curtains during the hottest part of the day to block out sunlight and reduce the heat entering your home.
• Avoid Drastic Temperature Changes: Avoid setting the thermostat to a significantly lower temperature than the outside air. This doesn’t cool the space faster but can lead to energy wastage.
• Seal Windows and Doors: Check for drafts around windows and doors. Seal any gaps with weather stripping to prevent cool air from escaping and warm air from entering.
• Use Programmable Thermostats: If your home has a programmable thermostat, use it to create cooling schedules based on your daily routine. This helps save energy when you’re not at home.
• Limit Use When Away: When leaving your home for an extended period, consider turning the air conditioning system off or setting it to a higher temperature to conserve energy.
• Report Maintenance Issues: If you notice any unusual sounds, leaks, or performance issues with the air conditioning system, report them to your property manager promptly for maintenance.
• Keep Outdoor Units Clear: If you have a window or split system, ensure that the outdoor unit is free from obstructions such as plants or debris. Adequate airflow enhances efficiency.
• Regular Cleaning: Keep the air vents and indoor unit clean from dust and debris. Regular cleaning ensures better air quality and system performance.
• Communicate with Property Manager: Maintain open communication with your property manager regarding any concerns or issues with the air conditioning system. They can arrange for maintenance or repairs as needed.

Proper use of your home’s evaporative cooling system

• Understand the Evaporative Cooling System: Familiarize yourself with the evaporative cooling system in your home. This system uses water to increase humidity and cool the air, making it different from traditional air conditioning. 
• Set the Right Airflow: Ensure that doors and windows are partially open to allow proper air circulation. Evaporative coolers work by drawing in fresh air from outside, so ventilation is crucial for effective cooling.
• Maintain a Comfortable Humidity Level: Evaporative coolers add moisture to the air. Aim for a humidity level between 40-60% for optimal comfort. If humidity becomes too high, it can impact cooling efficiency.
• Run the pump for a few minutes before switching to cooling mode: For an evaporative cooler to work, the pads must first be saturated with water. Give your system a few minutes to saturate the cooling pads by running it in “Pump” mode (if available) before turning on the fan to “Cool” mode.
• Set the Right Cooling Mode: Evaporative coolers often have different modes such as “Cool” and “Vent.” In warm weather, use the “Cool” mode, and switch to “Vent” when you only want air circulation without additional cooling.
• Use Fans for Circulation: Use ceiling fans or portable fans to improve air circulation within the home. This enhances the cooling effect of the evaporative cooler.
• Close Windows When Not in Use: When the evaporative cooler is turned off or not in use, close doors and windows to prevent warm air from entering the home.
• Monitor Outdoor Air Quality: Pay attention to outdoor air quality. If outdoor air is very humid or polluted, it can impact the performance of the evaporative cooler.
• Report Maintenance Issues: If you notice any unusual sounds, leaks, or performance issues with the evaporative cooling system, report them to your property manager promptly for maintenance.
• Emergency Shut-Off: Familiarize yourself with the emergency shut-off procedures for the evaporative cooler. If you encounter a problem, contact your property manager or maintenance team promptly.
• Communicate with Property Manager: Maintain open communication with your property manager regarding any concerns or issues with the evaporative cooling system. They can arrange for maintenance or repairs as needed.

A quick guide to thermostats

General information:

The temperature you set on a thermostat is the temperature the heating or air conditioning system will attempt to maintain. Setting a very high or very low temperature on your thermostat will not heat or cool your home faster. For example, if it’s cold inside and you want it to be 72 degrees, setting your thermostat to 80 degrees will not heat it up faster than if you simply set it to 72 degrees (but it will continue heating past 72 degrees until it reaches 80 degrees inside). Set the temperature you want your thermostat to maintain in your home and give the system time to heat or cool to that temperature.
