Taking advantage of cooler temperatures at night by keeping your windows open is a great idea. Close them first thing in the morning, and keep your shades and curtains drawn when it's sunny outside to prevent the sun from heating up the house.

Cooking outside on your grill is another way to keep the heat out of the house.

To accurately measure the temperature of your air conditioning system's performance, use an infrared thermometer to gauge the air temperature differential between the air coming from your supply vents and the return air.

Measuring the temperature of the air being expelled from your air conditioning system is crucial. To do this, locate the supply vent, verify that your infrared thermometer is correctly calibrated, position the thermometer so it's directly facing and perpendicular to the opening of the supply vent, and activate the measurement function to obtain a reading for the temperature of supply air.

Taking several measurements at different spots around the return vent is essential for accuracy. This will give you a reliable indication of your system's performance.

Here are some key steps to measure your AC's efficiency:

By following these simple tips, you can maximize your home's AC efficiency and stay cool and comfortable all summer long.

Maintaining the right temperature differential is crucial for AC performance. The ideal air temperature coming out of AC vents should be between 14 to 20 degrees Fahrenheit cooler than the return air temperature.

Running your HVAC equipment for at least fifteen minutes before measuring temperature is essential. This ensures you're assessing performance under stable operating conditions.

If the return air enters at 95°F, the air coming out of the supply vents should ideally be between 75°F and 81°F. This temperature range ensures comfort and energy efficiency in your living space.

Maintaining temperatures within this range prevents undue stress on your HVAC system, which could lead to higher utility costs or excessive wear.
