Reduce Air Conditioning Costs and Save Money

During this heat spell, you may feel helpless as you watch your cooling bill increase, but we’re going to instill some confidence back in you by telling you all the effective ways to reduce air conditioning costs… without having to suffer! Learn how to reduce summer cooling costs now and save money for years to come!

How to Beat the Heat and Reduce Air Conditioning Costs

1. Turn it up

For every degree you turn up the thermostat, that’s 5-10% of your hard-earned money back in your pocket, so operate your air conditioner at a higher temperature. To ensure lower operating costs, we recommend keeping your thermostat at no lower than 78 degrees. Raise the temperature to 84 degrees or higher when away from home. We suggest using a programmable thermostat so you can remotely control the temperature of your home.

Use ceiling fans in conjunction with higher temperatures to help keep you cool. The moving air will cool your skin and help you feel more comfortable. Operating at higher temperatures without also using some type of fan can start to feel a little too hot or stuffy.

2. Block outside heat sources

In order for that 78 degrees to feel more comfortable, you’ll need to minimize heat gain. That means closing any blinds or drapes to stop the heat from entering into your home. You can also help keep your home shaded by adding trees to block direct sunlight or using glare-free solar window screens.

Strategically placed trees can save you up to 30 percent on your home’s heating and cooling costs. That’s anywhere from $100-$250 annually.

3. Insulate your attic

Attic insulation is the “blanket” of your home, working to keep cold/hot air in its necessary placement, whether that’s inside or out, depending on the season.

You can save up to $600 annually by ensuring proper attic insulation. Check to see if your attic has adequate insulation by simply looking across your attic floor. A good indicator of a poorly insulated attic is if the existing insulation barely reaches the tops of the joists. You can test the R-value (level of insulation) of your attic with just one tool: a ruler.

However, if it not only covers the joists but is well above them, adding more insulation won’t save you all that much on energy costs. There are three different methods for adding insulation: roll-on or blanket, loose-fill or blown-in, and sprayed foam polyurethane.

4. Seal leaks

Your home could be letting in hot/cold air without you even knowing it! It’s time to inspect your home for any possible leaks, and repair them using the proper method. Check out House Logic’s “8 Easy Ways to Seal Air Leaks Around the House” for fool-proof ways to seal those pesky air leaks!

Whether there’s a massive leak in your ductwork, or a pinhole leak in a bedroom window, repairing them will definitely save on air conditioning costs. A little work can go a long way.

5. Change the air filter

One of the easiest things you can do as a homeowner to ensure your HVAC system operates at optimal efficiency is changing the air filter at the appropriate time. Have you ever vacuumed your home over and over again to no avail? If you don’t frequently replace your air filter, all that dust, dirt, and other debris continues to accumulate in your home no matter how well you clean.

Much like a vacuum, if you forgo changing your air filter, your system will start to lose efficiency and will eventually stop working. Dirty air filters can cause a variety of problems such as blocked airflow and poor indoor air quality. Remember to change your air filter every 30-60 days. Write on post-its, set calendar reminders, and write the date on your air filter when you replace it to help you remember this important home maintenance task.

The U.S. Department of Energy says that maintaining a clean air filter can lower your heating and cooling costs by 5-15 percent.

6. Schedule regular HVAC tune-ups

We’re already well into the cooling season, but that doesn’t mean it’s too late. We recommend scheduling annual tune-ups to ensure your system cools effectively. This will prevent breakdowns on summer’s hottest day when you need cool air the most.

Cassel Home Comfort’s certified, trusted technicians will inspect your entire system, even the nooks and crannies, to make sure it operates at optimal efficiency.

Should our technicians find a problem that needs repairing immediately, we will notify you and provide you with upfront pricing so that you can make an informed decision.
