How Do I Control the Temperature of My Central Air Conditioner?

Published in HVAC Systems 2 mins read

You primarily control the temperature of your central air conditioner using the thermostat.

Here's a breakdown of how it works:

  • Locate Your Thermostat: This is usually a small device mounted on a wall, often in a central location in your home.

  • Thermostat Types: Thermostats come in various forms:

    • Manual Thermostats: These have a dial or slider that you physically move to set the desired temperature.
    • Digital Thermostats: These have a digital display and buttons or a touchscreen to set the temperature.
    • Smart Thermostats: These connect to your Wi-Fi network, allowing you to control them remotely via a smartphone app. They also often learn your preferences and can automatically adjust the temperature based on your schedule.
  • Adjusting the Temperature:

    • Increasing the Temperature: Typically, you'll find "Temp Up" or "+" buttons to raise the set temperature. Press these repeatedly until you reach your desired setting. The AC will run less frequently to maintain this warmer temperature.
    • Decreasing the Temperature: Similarly, look for "Temp Down" or "-" buttons to lower the set temperature. Press these until you reach your desired cooler setting. The AC will run more to maintain this cooler temperature.
  • Understanding the Set Point: The temperature displayed on your thermostat is the set point. This is the temperature your air conditioner will attempt to maintain in your home.

  • Factors Affecting Temperature: Remember that external factors like sunlight, insulation, and the number of people in the house can affect how quickly the air conditioner can reach and maintain the set point.

  • Energy Saving Tips: A few degrees difference in your thermostat setting can significantly impact your energy bill. Consider raising the temperature slightly when you're away from home or asleep.
