Understanding Energy Consumption and How to Save Money This Season

As temperatures rise, so do energy bills – especially for homeowners relying on air conditioning to stay comfortable. Understanding how your air conditioner consumes energy and what factors influence usage is the first step to saving money this cooling season. With a few practical tips and a better grasp of your utility bill, you can reduce energy waste without sacrificing comfort.

What Affects Your AC’s Energy Consumption?

1. AC Unit Efficiency

The efficiency of your air conditioner, often measured by its SEER2 (Seasonal Energy Efficiency Ratio 2) rating, greatly impacts energy use. Higher SEER2 ratings mean the unit uses less energy to produce the same cooling effect. Older or poorly maintained units typically have lower efficiency.

2. Size and Condition of the AC System

An AC that’s too large or too small for your home wastes energy. Oversized units cycle on and off frequently, while undersized units run constantly trying to keep up. Additionally, dirty filters, clogged coils, or refrigerant leaks make your system work harder, increasing consumption.

3. Thermostat Settings and Usage

Lower thermostat settings cause your AC to work harder and longer, consuming more energy. Each degree cooler can add 3-5% to your cooling costs. Using programmable thermostats to adjust temperatures when you’re away or asleep helps minimize unnecessary energy use.

4. Home Insulation and Air Leakage

Poor insulation and air leaks allow cool air to escape and warm air to enter, making your AC run longer. Windows, doors, attics, and ductwork are common culprits. Well-sealed and insulated homes maintain temperature more efficiently.

5. Outdoor Temperature and Humidity

Hotter, more humid days increase the cooling load on your AC. High humidity means your system works extra to remove moisture from the air, which also uses more energy.

Tips to Improve AC Efficiency and Save Money

1. Schedule Regular Maintenance

Annual HVAC tune-ups ensure your system runs at peak efficiency. Our technicians clean coils, check refrigerant levels, and inspect electrical components to prevent issues that waste energy.

2. Change Air Filters Frequently

Clogged or dirty filters restrict airflow, forcing your AC to work harder. Replace filters every 1-3 months during heavy use.

3. Use a Programmable or Smart Thermostat

Set your thermostat higher when you’re away and lower before you return. Smart thermostats can learn your schedule and optimize cooling automatically.

4. Seal and Insulate Your Home

Seal gaps around windows, doors, and ductwork to prevent air leaks. Adding insulation in attics and walls keeps your home cooler naturally.

5. Use Fans to Circulate Air

Ceiling or portable fans help distribute cool air evenly, allowing you to set your thermostat a few degrees higher comfortably.

6. Limit Heat-Generating Activities

Run appliances like ovens, dishwashers, and dryers during cooler morning or evening hours to reduce indoor heat buildup. Monitor and control your energy use with these tips:

• Track your energy usage over time to identify spikes related to AC use or other appliances.
• Use online tools or apps offered by your utility to monitor daily and hourly consumption.
• Consider energy audits to find hidden energy waste and get professional recommendations.
