Ways to Save Money on Air Conditioning in Virginia
Virginia summers have a way of putting air conditioning systems to the test. Between the heat and humidity, it doesn’t take long for cooling costs to climb. The good news is that many of the best ways to save money on air conditioning are simple, affordable, and easy to build into your routine.
At McCarthy Services, we’re dedicated to helping Virginia homeowners get the most from their cooling systems. Whether you’re turning your AC back on after winter, looking to lower your monthly utility bills, or simply trying to stay comfortable without overworking your system, this guide provides practical tips that make a real difference.
Best Thermostat Settings to Lower Your Bill
Your thermostat setting has a bigger impact on cooling costs than almost any other habit. Instead of constantly adjusting the temperature throughout the day, focus on a schedule that balances comfort and efficiency. Learning how to save on air conditioning often starts with making small thermostat changes that reduce how hard your system has to work.
Start at 78°F: The U.S. The Department of Energy recommends setting your thermostat to 78°F when you’re not home. Adjust as needed to be comfortable when you’re home, if possible keeping it around the mid-70s.
Raise the temperature when you can: Increasing the setting by 7–10°F for at least eight hours a day, such as when you’re at work, can lower annual heating and cooling costs by up to 10%.
Sleep comfortably: Many homeowners prefer a modest nighttime adjustment rather than significantly lowering the thermostat.
Consider a smart thermostat: Smart thermostats can make these adjustments automatically for effortless savings.
Should You Run AC All Day or Turn It Off?
If you’re leaving for work, errands, or a trip, raise the thermostat temperature instead of cooling an empty house at your usual setting. Turning the AC off entirely may save more during an extended absence, but the home can take longer to cool when you return. Completely shutting off the AC for extended periods (especially in the summer) can also lead to increased humidity in your home.
How to Improve AC Efficiency
The average home spends around $1,900 annually on utility bills, with almost half of that going to cooling and heating. Improving energy efficiency can reduce these costs, so it’s worth learning how to save money on air conditioning.
Replace dirty filters: Check filters monthly during heavy summer use and replace them when they look clogged or dirty.
Keep vents open and clear: Move furniture, rugs, and curtains away from supply vents and return grilles.
Seal air leaks: Use caulk or weatherstripping around windows, doors, and other gaps where cooled air can escape.
Add or improve insulation: Can you improve AC efficiency with insulation? Absolutely! Proper attic and wall insulation helps slow heat transfer into the home.
Use ceiling fans correctly: Run fans counterclockwise in the summer so you can feel comfortable at a slightly higher thermostat setting.
Close curtains during peak sun: Cover south- and west-facing windows when afternoon heat is strongest.
Clear the outdoor unit: Keep your outdoor condenser clear of leaves, grass, and other debris.
Schedule AC maintenance: A professional checkup can identify worn parts, airflow restrictions, and other efficiency problems before they worsen.
When to Upgrade Older AC Equipment
If your cooling costs keep climbing even after you’ve adjusted the thermostat and stayed on top of AC repairs and maintenance, the system itself may be the issue.
One of the most effective ways to save money on air conditioning is replacing an older system that’s no longer capable of operating efficiently. Here are some signs it may be time for an upgrade:
Your system is 8–10+ years old: Older equipment is often less efficient than newer models.
Repairs are becoming more frequent: Repeated AC repair costs can quickly add up, making a new installation a great investment.
Energy bills keep increasing: Higher cooling costs without a clear cause may point to declining efficiency.
Your home never feels comfortable: Uneven temperatures, high humidity, or constant running may indicate your AC is no longer keeping up.
Major components have failed: Expensive repairs on an older unit often make a replacement the better investment.
Additional Tips and Resources
Looking for additional ways to save money on air conditioning? We recommend:
Checking Virginia Energy Connect: Search for rebates, tax incentives, and efficiency programs in your area.
Scheduling a home energy audit: Many Virginia utility providers offer in-home energy assessments that identify opportunities to reduce cooling costs.
Looking for utility rebates: Depending on your provider, you may qualify for incentives on smart thermostats, insulation, HVAC upgrades, or other energy-saving improvements.
Exploring weatherization assistance: Income-qualified households may be eligible for insulation, air sealing, and other upgrades that improve comfort and lower energy bills.
