The Best Thermostat Settings for a Hot Summer

During the long, hot summer months, choosing the right thermostat settings is essential for maintaining indoor comfort while keeping energy costs under control. Proper thermostat settings not only help improve comfort but also reduce the workload on your HVAC system, allowing it to operate more efficiently. Here’s what you need to know about the best thermostat settings for summer, practical ways to maximize energy savings, and how to get the most from your cooling system.

Why 78°F Is the Ideal Summer Setting

The U.S. Department of Energy and leading HVAC manufacturers recommend setting your thermostat to 78°F when you are home and need cooling. In Visalia, CA, where summer temperatures often climb into the triple digits, this setting offers an excellent balance between comfort and energy efficiency. Benefits include:

• Improved system efficiency because your air conditioner cycles less frequently.
• Lower cooling costs, as increasing your thermostat by just one degree can reduce energy consumption.
• Less wear and tear on your HVAC system, helping reduce the need for air conditioning repair.

If your family prefers a cooler indoor environment, gradually increase your thermostat setting by one or two degrees every few days. You may find that you’re just as comfortable at a slightly higher temperature, especially when combined with other cooling strategies.

Optimizing Thermostat Settings While You’re Away

Allowing your air conditioner to run continuously while no one is home can significantly increase energy costs. When you’re away for work or running errands, setting your thermostat between 85°F and 88°F helps reduce unnecessary cooling. A programmable or smart thermostat can automatically return your home to a comfortable temperature before you arrive.

For extended vacations, avoid setting your thermostat above 90°F. Maintaining a reasonable indoor temperature helps protect your home’s furnishings, electronics, and indoor air quality. Many homeowners choose smart thermostats as part of their air conditioning installation because they provide convenient scheduling and improved energy management.

Humidity Control: An Important Part of Summer Comfort

Although the climate is generally dry, occasional increases in humidity can make your home feel warmer than the thermostat indicates. A properly functioning air conditioner helps remove excess moisture while cooling your home. That’s why routine air conditioning maintenance is essential. If your home continues to feel humid or you notice musty odors, consult an HVAC professional about solutions such as a whole-home dehumidifier.

Enhancing Comfort with Fans and Window Treatments

In addition to proper thermostat settings, several simple strategies can improve comfort while reducing energy use:

• Set ceiling fans to rotate counterclockwise during the summer to create a cooling breeze.
• Keep blinds and curtains closed during the hottest part of the day to block solar heat.
• Use ovens, dryers, and other heat-producing appliances during the evening whenever possible.

These simple habits help reduce the workload on your air conditioner and improve overall indoor comfort.

The Importance of Regular AC Maintenance

Keeping your air conditioner properly maintained helps ensure reliable performance throughout the summer. Scheduling annual air conditioning maintenance allows technicians to replace filters, clean coils, inspect refrigerant levels, and identify potential issues before they become expensive repairs. Regular maintenance also helps improve energy efficiency, extend the lifespan of your equipment, and reduce the risk of unexpected breakdowns.

Upgrade to a More Energy-Efficient Cooling System

If your current air conditioner is more than 10 years old or requires frequent repairs, replacing it with a modern, high-efficiency system may be the best long-term solution. Today’s systems offer improved SEER2 ratings, variable-speed operation, and smart technology that deliver greater comfort while using less energy. A professional air conditioning installation can also improve indoor air quality and lower your monthly utility costs.
