A New Homeowner’s Guide to Understanding Your AC System in Summer

Congratulations on becoming a new homeowner! As you settle into your new abode, one of the essential systems you’ll rely on during the warmer summer months is your air conditioning (AC) system. Understanding how your AC works and how to care for it will ensure a comfortable and enjoyable summer. In this simple guide, we’ll walk you through the basics of your AC system and offer some helpful tips to keep it running smoothly all season long.

  1. Know Your AC Basics:

Before we delve into the details, let’s cover the basics of how your AC system works. An air conditioner is designed to remove heat and humidity from indoor air, providing cool and refreshing air in return. The primary components of your AC system are:

  • Compressor: Located in the outdoor unit, the compressor circulates refrigerant that absorbs and releases heat.
  • Evaporator Coil: Inside your home, the evaporator coil cools the air by absorbing heat from it.
  • Condenser Coil: This coil, situated in the outdoor unit, releases the heat collected from inside your home.
  • Thermostat: The thermostat allows you to control the temperature and settings of your AC system.
  1. Set Your Thermostat Wisely:

During the summer, setting the thermostat at the right temperature is crucial for comfort and energy efficiency. Aim for a temperature that keeps you cool without overworking your AC. A recommended setting is around 72-76 degrees Fahrenheit (22-24 degrees Celsius) when you’re at home. Consider raising the temperature a few degrees when you’re away to save on energy bills.

  1. Practice Regular Maintenance:

Keeping your AC system well-maintained is essential for its performance and longevity. Here are some simple maintenance tasks to remember:

  • Clean or Replace Filters: Dirty air filters can restrict airflow and reduce cooling efficiency. Check and clean or replace your filters every one to three months, depending on the type of filter and usage.
  • Clear Outdoor Unit: Ensure the outdoor unit is free of debris, leaves, and any obstructions that might hinder airflow. Keep plants and shrubs at least two feet away from the unit to allow proper ventilation.
  • Schedule Professional Maintenance: At least once a year, schedule a professional HVAC technician to inspect and tune-up your AC system. They’ll check refrigerant levels, clean coils, and ensure all components are in good working condition.
  1. Utilize Fans and Natural Ventilation:

To complement your AC’s cooling efforts, use ceiling fans or portable fans to help circulate the cool air. Fans create a wind-chill effect, making you feel cooler without lowering the temperature significantly.

  1. Sealing and Insulation:

Ensure your home is well-insulated and sealed to prevent cool air from escaping and hot air from entering. Check for any gaps or cracks around windows, doors, and ducts, and seal them to maintain a comfortable indoor temperature.


With these basic tips, you’re well-equipped to understand and care for your AC system during the warmer summer months. Remember to set your thermostat wisely, perform regular maintenance, utilize fans, and keep your home well-insulated. By following these steps, you’ll enjoy a cool and comfortable living space while saving energy and ensuring your AC system’s efficiency and longevity for years to come. Happy summer!
