Staying Cool in Grayson, GA: Your Complete Summer AC Guide
Georgia summers in Grayson and throughout Gwinnett County are no joke. With temperatures regularly climbing into the upper 90s and humidity that makes it feel well over 100°F, your air conditioning system is the most important appliance in your home from June through September. Henson Heating Air and Plumbing has helped Grayson homeowners stay cool for years, and we've compiled our best summer cooling tips to help you maximize comfort while minimizing energy costs.
Optimal Thermostat Settings for Grayson Summers
One of the most common questions we receive from Grayson homeowners is what temperature to set their thermostat at during our brutal summer heat. The answer depends on your comfort preferences, but here are our recommendations:
When You're Home
The U.S. Department of Energy recommends 78°F when you're home during summer. While this might seem warm, setting it lower than necessary wastes energy and puts extra strain on your system during Georgia's hottest months. Most Grayson families find 74-78°F comfortable when combined with ceiling fans.
When You're Away
When leaving your Grayson home for more than a few hours, set your thermostat to 85°F. Every degree you raise the thermostat when you're away saves approximately 3% on your cooling costs. For Grayson residents who leave for vacation, keep the home at 85°F to prevent humidity damage and mold growth — don't turn the AC off completely during Georgia summers.
Using a Smart or Programmable Thermostat
One of the best investments Grayson homeowners can make is a smart or programmable thermostat. These devices automatically adjust temperatures based on your schedule, ensuring your home is cool when you need it and conserving energy when you don't. Henson Heating Air and Plumbing can install and configure a smart thermostat for your Grayson home.
Essential Summer AC Maintenance Tips for Grayson Homeowners
Regular maintenance between professional tune-ups is essential for reliable cooling all summer. Here's what Grayson homeowners should do throughout the summer season:
Replace or Clean Your Air Filter
During peak cooling season in Grayson, you should check your air filter every 30 days and replace it when it looks dirty. A clogged filter is one of the leading causes of AC problems in our area. It restricts airflow, makes your system work harder, and can cause the evaporator coil to freeze — leaving you without cooling on the hottest days.
Keep the Outdoor Unit Clear
Your outdoor condenser unit needs clear airflow to release heat effectively. Keep at least 2 feet of clearance around the unit by trimming back shrubs and vegetation. Don't stack items against it and clean any debris that accumulates around the unit. In Grayson, summer storms can leave leaves and debris around condenser units.
Check and Clear the Condensate Drain
Georgia's high humidity means your AC removes significant amounts of moisture from the air, which drains away through the condensate line. If this line becomes clogged, water can back up and damage your home. Check periodically for water near your indoor unit, and call Henson Heating Air and Plumbing right away if you notice any water pooling.
Use Ceiling Fans Wisely
Ceiling fans should run counterclockwise in summer to create a cooling breeze. Combined with your AC, ceiling fans allow you to raise your thermostat by 4°F without reducing comfort. Just remember: ceiling fans cool people, not rooms — turn them off when you leave the room.
Signs Your AC Needs Help During a Grayson Summer
Knowing when to call Henson Heating Air and Plumbing can prevent a minor issue from becoming a major breakdown. Contact us right away if you notice:
- Your Grayson home isn't reaching the set temperature even after running for an extended period
- Your AC is short cycling (turning on and off frequently every few minutes)
- You hear unusual noises like grinding, squealing, or clanking from your system
- Ice is forming on your refrigerant lines or indoor unit
- Your energy bill has spiked significantly without a corresponding change in usage
- There are musty odors when the AC runs (possible mold in the system or ductwork)
- Water is pooling near your indoor air handler
Energy Efficiency Tips for Grayson Homes
Beyond your AC system itself, there are many things Grayson homeowners can do to reduce cooling costs and keep their home comfortable:
Block Summer Heat at the Source
Close blinds and curtains on south and west-facing windows during the hottest parts of the day. Window coverings can reduce solar heat gain by up to 77%, significantly reducing the load on your AC system. Grayson homeowners might also consider reflective window film for particularly problematic windows.
Seal Air Leaks
Cool air escaping through gaps around doors, windows, and other openings forces your AC to work harder. Check weatherstripping and caulking around all exterior openings. Ductwork leaks are also a major source of energy loss — Henson Heating Air and Plumbing can perform duct testing to identify and seal leaks in your Grayson home.
Minimize Heat Generation Indoors
Cooking, running the dishwasher, and using the clothes dryer all add heat to your Grayson home. During the hottest summer days, grill outdoors, run dishwashers and laundry at night, and switch to LED bulbs throughout your home to reduce heat generation.

Frequently Asked Questions
What temperature should I set my AC to in Grayson during a summer heat wave?
During Georgia heat waves in Grayson, we recommend keeping your thermostat at 76-78°F when home and using ceiling fans to supplement cooling. Avoid setting it too low as this puts excessive strain on your system and can cause it to freeze up or break down during the hottest days.
How often should I change my AC filter during Grayson summers?
During the peak cooling season in Grayson and Gwinnett County, check your filter monthly and replace it as soon as it looks dirty — often every 4-6 weeks during heavy summer use. A clean filter is essential for efficient cooling and preventing expensive breakdowns.
Why is my AC running constantly but not cooling my Grayson home?
If your AC in Grayson runs constantly without reaching the set temperature, it could indicate a refrigerant leak, dirty coils, a failing compressor, or a system that's undersized for your home. Call Henson Heating Air and Plumbing right away — running a struggling system can cause further damage.
Is it safe to turn my AC off when I leave my Grayson home for vacation?
No — Grayson homeowners should never turn the AC completely off during Georgia summers. The extreme heat and humidity can cause moisture damage, mold growth, and can harm electronics and furniture. Set it to 85°F when away to balance efficiency with protection for your home.
How can I reduce my summer electric bill in Grayson without being uncomfortable?
Grayson homeowners can significantly reduce summer electricity costs by using ceiling fans to raise the thermostat 4°F, sealing air leaks, blocking solar heat gain with window coverings, and scheduling an AC tune-up to ensure the system is running at peak efficiency.
