How To Save on Cooling Costs During Oklahoma’s Late Summer Heat

As summer drags into the dog days and beyond, late-season cooling costs take an increasing toll on household budgets.
During late spring, Tulsa residents may pay from $60 to $150 per month for cooling, while by late summer, that cost goes up to $120 to $300 per month.
ProThermal Heating and Cooling shares practical tips on how to save on cooling costs during the late summer heat.
1. Check Thermostat Settings
Try adjusting your thermostat to 78 degrees when you are home and 7-10 degrees higher when you are away to save up to 10% on energy expenses.
Consider investing in a smart programmable thermostat to make adjustments automatically or remotely, and you can make sure your indoor air is comfortable when you arrive home.
2. Improve Insulation
Check the insulation in your attic, walls, and floors. Look for gaps around windows and doors that allow air to escape. Proper sealing and insulation prevent paying for cool air only to have it escape into the outdoor heat. Your air conditioner will work under less stress, saving utility costs and extending its lifespan.
3. Use Ceiling Fans
Improved interior circulation provides a wind-chill effect without needing to actually reduce temperatures. Set fans to rotate counterclockwise in summer, and try moving your thermostat up four degrees to save money without sacrificing comfort.
4. Schedule Regular Air Conditioning Maintenance
One of the best tips for how to save on cooling costs is to schedule regular professional maintenance. Professional cleaning and inspections at least annually will keep your system running at peak efficiency, saving up to 15% on energy costs.
5. Use Blinds and Improve Shading
Shading against the sun’s radiant heat makes your air conditioner’s job much less stressful. Think about new trees, awnings, and structures like pergolas to provide extra shading for your house and the concrete and ground around it. Keep blinds and curtains closed during midday and late afternoon, especially those facing south or west.
6. Take Advantage of Natural Ventilation
Take advantage of natural ventilation during cooler evenings by opening windows and using fans to circulate fresh air. Refreshing interior cross-ventilation can stack energy savings by giving your HVAC unit an extended break during the coolest part of the day.
7. Limit the Use of Heat-Generating Appliances
Try using your microwave or air fryer during the daytime instead of heating up your oven or stove. Run your dishwasher and dryer at night to reduce the radiant heat that they discharge.
8. Consider Upgrades for Energy Efficiency
Older HVAC systems have significantly lower SEER energy efficiency ratings than newer models. Your home might also be a good fit for a ductless mini-split or heat pump system that can provide more targeted and less expensive cooling power.
