Beating the Heat in Lawrenceville, GA
As the county seat of Gwinnett County and one of Metro Atlanta's most vibrant cities, Lawrenceville, Georgia has no shortage of warm, humid summer days. With temperatures regularly hitting the 90s from June through August, and humidity that makes it feel even hotter, having a well-functioning and efficiently operated air conditioning system is essential. Henson Heating Air and Plumbing has been helping Lawrenceville homeowners stay cool, and here are our top summer cooling tips for your home.
Smart Thermostat Settings for Lawrenceville Summers
How you operate your thermostat has a significant impact on both your comfort and your energy bills in Lawrenceville:
- 78°F when home – The optimal setting for comfort and efficiency in Gwinnett County's summer climate
- Raise to 82-85°F when away – Don't turn the AC completely off — the system will have to work harder to cool back down, and humidity can damage your home
- Use ceiling fans effectively – Running fans in occupied rooms allows you to raise your thermostat by 4°F without discomfort
- Invest in a smart thermostat – Programmable and smart thermostats can reduce your cooling costs by 10-15% through automatic temperature adjustments
- Night setback strategy – Lawrenceville summer nights are often cooler than days. Use programmable thermostat schedules to take advantage of these cooler periods
AC Maintenance Tips for Lawrenceville Homeowners
Your air conditioner works hard during Lawrenceville summers. Keep it performing optimally with these maintenance steps:
Monthly Filter Checks
During Gwinnett County's summer cooling season, your AC runs nearly continuously. Check and replace air filters monthly — a clogged filter is one of the most common causes of reduced cooling efficiency and system breakdowns.
Outdoor Unit Care
Keep the area around your outdoor condenser unit clear. Remove grass clippings, leaves, and debris. Trim vegetation back at least 2 feet from all sides. Rinse the unit with a garden hose periodically to clean dirt from the coils.
Condensate Line Maintenance
Lawrenceville's high humidity means your AC produces significant condensation. A clogged drain line can cause water damage and system shutdowns. Use a wet/dry vacuum to clear blockages or pour vinegar down the line monthly to prevent algae growth.
Professional Service
If you haven't had a spring tune-up, call Henson Heating Air and Plumbing immediately. Don't wait for your Lawrenceville AC system to fail on the hottest day of the summer — preventive service is always less expensive than emergency repairs.
Reduce Heat Gain in Your Lawrenceville Home
The less heat your home absorbs, the less your AC has to work. Lawrenceville homeowners can reduce cooling load with these strategies:
- Window coverings – Close blinds and curtains on windows facing south and west during afternoon hours when solar heat gain is highest
- Door seals – Check weatherstripping on doors. Gaps allow hot Lawrenceville outdoor air to infiltrate your conditioned space
- Attic insulation – Adequate attic insulation prevents heat from radiating down into living spaces, significantly reducing cooling loads
- Cooking alternatives – Use outdoor grills, slow cookers, or air fryers instead of the oven on hot days to reduce indoor heat generation
- Hot water activities – Run dishwashers and washing machines in the evening when temperatures are lower
Identifying AC Problems Early in Lawrenceville
Catching AC problems early prevents expensive breakdowns during Gwinnett County's peak summer heat. Watch for these warning signs:
- AC running constantly without reaching the set temperature
- Unusual sounds: grinding, squealing, clicking, or banging
- Warm air coming from vents when the thermostat is set to cool
- Ice visible on refrigerant lines or around the indoor unit
- Unusually high electric bills
- Excess humidity indoors (you feel sticky even with the AC running)
- Water puddling around the indoor air handler

Frequently Asked Questions: Summer Cooling in Lawrenceville, GA
What's the ideal humidity level for a Lawrenceville, GA home in summer?
Indoor relative humidity should be maintained between 30-50% for comfort and to prevent mold growth. In Lawrenceville's humid summer climate, your AC naturally removes moisture, but if humidity stays above 60% indoors, a whole-home dehumidifier may be needed. Signs of excess humidity include condensation on windows and a sticky, clammy feeling indoors.
How can I tell if my Lawrenceville AC is low on refrigerant?
Signs of low refrigerant in a Lawrenceville home include: the AC blowing warm or slightly cool air, ice forming on the refrigerant lines, the system running constantly without reaching the thermostat setting, and higher than normal electricity bills. Low refrigerant requires a licensed HVAC technician — it's illegal to add refrigerant without proper certification. Call Henson Heating Air and Plumbing for a diagnosis.
Why does my Lawrenceville home feel so humid even with the AC running?
Several issues can cause excess humidity in Lawrenceville homes even with the AC running: the system may be oversized (running in short cycles that don't adequately dehumidify), it may have low refrigerant, the evaporator coil might be dirty, or the home may have significant air infiltration. A professional inspection from Henson Heating Air and Plumbing can identify the specific cause.
Is it worth getting a smart thermostat for my Lawrenceville home?
Absolutely. In Lawrenceville, GA, where cooling systems run for 6+ months of the year, a smart or programmable thermostat can save 10-15% on cooling costs. With Georgia Power rates, that can mean $100-$200 or more in annual savings. Modern smart thermostats also provide valuable insights into your system's operation and can alert you to potential problems early.
How often should I have my Lawrenceville AC serviced?
Most HVAC professionals recommend annual service — ideally a spring tune-up before the cooling season begins. However, for older systems (10+ years), semi-annual service is worth considering. Given Gwinnett County's demanding summer climate, well-maintained systems last longer and perform better. Henson Heating Air and Plumbing offers maintenance plans to keep your Lawrenceville system running optimally.
What AC efficiency rating should I look for when replacing my Lawrenceville AC?
For Lawrenceville, GA and the greater Gwinnett County area, we generally recommend a minimum of 16 SEER (Seasonal Energy Efficiency Ratio). Given Georgia's long cooling season, higher efficiency systems (18-20+ SEER) provide excellent returns on investment through significantly lower electricity bills. Our Lawrenceville technicians can help calculate the payback period for different efficiency options based on your home's specific characteristics.
