If you’re looking for quick energy-saving tips that will show results right away, here are some easy and affordable changes you can make to start saving.
💡 1. Thermostat Tips — The First Step to Efficiency
Your thermostat is essentially the brain of your system. It controls when your system turns on, how long it runs, and the temperature of your home. By adjusting your thermostat settings, you can make a big impact on your cooling and heating costs.
Best Temperature Settings:
-
Summer: Set your thermostat to 78°F while you’re home and active. If you’re away for several hours or at work, increase it by 5–10°F (73°F or 74°F) to save energy without compromising comfort.
-
Winter: Set your thermostat to 68°F while you're home, and lower it to 60–62°F at night or when you're away.
Savvy Tip: If you don’t want to think about adjusting your thermostat all the time, use a programmable thermostat. This will automatically raise or lower your home's temperature based on your schedule, ensuring maximum efficiency when you're home and away.
📱 2. Upgrade to a Smart Thermostat
If you haven't made the switch to a smart thermostat yet, it's time to consider it. A smart thermostat learns your schedule, optimizes temperature control, and even adjusts based on the weather outside. Some models even let you control your system remotely from your smartphone.
Energy Savings with a Smart Thermostat:
-
Set it to automatically adjust when you leave home. If you're gone for work, the thermostat can increase the temperature in the summer and lower it in the winter, ensuring you’re not cooling or heating an empty house.
-
Track your energy consumption: Some smart thermostats offer energy usage reports, which allow you to see exactly where you’re saving and where you can improve.
Savvy Tip: If you upgrade to a Wi-Fi-enabled smart thermostat, you can control the system from anywhere, even when you're traveling. It’s a game-changer for busy homeowners who want to maximize efficiency without sacrificing comfort.
🧹 3. Change or Clean Your Filters Regularly
The air filters in your R-32 packaged AC system serve as the first line of defense against dust, dirt, and allergens. Over time, they can get clogged and reduce airflow, making your system work harder. Cleaning or replacing your filters is one of the easiest and most important maintenance tasks you can do.
How Often to Change Filters:
-
Standard filters should be replaced every 60–90 days.
-
Washable filters should be cleaned thoroughly (with warm water and mild soap) every 30–60 days, depending on how frequently your system runs.
Savvy Tip: Use high-efficiency filters, such as pleated or HEPA filters. These types capture finer particles and can help reduce energy consumption, especially if you have pets or live in a dusty area.
💡 3️⃣ Insulation & Sealing — The Hidden Efficiency Hack
While your R-32 packaged AC system is designed to be energy-efficient, insulation and sealing play a huge role in ensuring your system isn’t overworking itself.
🔒 Why Insulation Matters
Proper insulation ensures that the cool air stays inside and the hot air stays out, preventing your system from constantly having to fight against heat gain in the summer or heat loss in the winter. The better your home’s insulation, the less energy your AC needs to maintain a comfortable temperature.
Where to Insulate:
-
Attics and crawl spaces are common areas for energy loss. Adding insulation here can make a big difference in overall efficiency.
-
Windows and doors are another common source of air leakage. Consider weather stripping or caulking gaps to reduce air exchange.
-
Walls and basements may also benefit from extra insulation if your home is older.
Savvy Tip: Adding R-8 or higher insulation to ducts in unconditioned spaces (like attics or crawl spaces) can improve your system’s efficiency by up to 20%.
🛠️ 4. Seal Leaks in Ductwork
Leaky ducts can account for up to 30% of energy loss in a home’s HVAC system. If your ducts are poorly sealed, cool air escapes into walls, attics, or crawl spaces instead of cooling your living areas.
What to Do:
-
Inspect visible ducts for holes or cracks.
-
Use duct sealant or metal tape (NOT regular duct tape) to seal leaks.
-
Consider adding insulation around ducts to improve efficiency.
Savvy Tip: If your ducts run through unconditioned spaces, insulate them to prevent temperature loss and boost energy efficiency.
🔧 4️⃣ Optimizing Your System — Maximizing R-32’s Efficiency
R-32 systems are already highly efficient, but there are ways to get even more out of your system by ensuring it operates at its best.
🌬️ 1. Clean the Coils Regularly
The condenser and evaporator coils in your system need to be cleaned at least twice a year. Dust and debris can accumulate on these coils and block airflow, causing the system to run longer than necessary.
How to Clean Coils:
-
Use a soft brush or vacuum to remove dirt from the condenser coils.
-
For the evaporator coils, gently clean them using compressed air or a soft brush.
Savvy Tip: Cleaning your coils twice a year can improve cooling efficiency by up to 30% and reduce the risk of system failure.
⚡ 2. Adjust Fan Settings
Many people think the fan should always be running, but keeping your system’s fan running continuously can waste energy.
-
Set the fan to auto mode, so it runs only when the system is cooling your home.
-
Constant fan use without the system cooling is an unnecessary energy drain.
Savvy Tip: Keep your fan on auto mode to avoid running up your electric bill.
🌿 5️⃣ Zoning — Targeted Cooling for Maximum Savings
One of the biggest energy drains is cooling spaces you don’t use. If you have multiple zones in your home, you can maximize efficiency by cooling only the rooms you use most.
🏠 How Zoning Works
Zoning allows you to divide your home into separate areas that each have their own thermostat and cooling control. This way, you’re not cooling unused rooms, which saves you energy.
-
Zone cooling works best if you have a larger home with separate living areas (e.g., upstairs and downstairs).
-
Even if you don’t have a built-in zoning system, consider closing vents in rooms you don’t use often, like guest rooms or storage areas.
Savvy Tip: If your home is especially large, consider installing a ductless mini-split in rooms that need independent temperature control.
🌡️ 6️⃣ Off-Season Efficiency — Get Ready for the Cooling Season
Your R-32 system is likely used more in the summer, but it’s important to maintain efficiency during the off-season too.
🌞 Pre-Summer Maintenance
Before the heat hits, it’s a good idea to get your system cleaned and checked by a professional. This preseason inspection ensures the system runs optimally once the warmer months arrive.
Savvy Tip: Schedule an annual maintenance check every spring, right before cooling season begins. It helps avoid emergency repairs during peak heat.
❄️ Winter Mode Efficiency
If you have a heat pump function on your R-32 system, you can use it for energy-efficient heating during cooler months. Heat pumps are often more energy-efficient than traditional heating systems, especially in moderate climates.
Savvy Tip: If you live in a cold climate, make sure to set your thermostat lower in winter (around 65°F) to reduce heating costs while allowing your R-32 system to work efficiently.
🧾 7️⃣ Annual Professional Check-Up — Don’t Skip It!
Even though you can handle a lot of maintenance yourself, it’s essential to schedule an annual professional check-up.
🧰 What a Professional Does
-
Refrigerant check: Ensures the refrigerant levels are correct and topped up.
-
Full-system inspection: A technician will check for mechanical problems and perform a thorough cleaning.
-
Component calibration: The system will be calibrated to ensure it operates optimally.
Savvy Tip: Schedule your professional check-up during off-peak seasons (fall or spring) when service is less expensive and technicians have more availability.
🌍 8️⃣ Upgrading Your System for Even Greater Efficiency
Your R-32 system is likely already one of the most efficient models available. However, if your system is getting up there in age, it may be time to consider upgrading to an even higher-SEER R-32 model for long-term savings.
🔧 Considerations for Upgrading
-
Newer models typically have higher SEER ratings (Seasonal Energy Efficiency Ratio), meaning better cooling with less energy.
-
Smart thermostat integration: Pairing a new system with a smart thermostat can improve performance and efficiency even more.
Savvy Tip: Upgrading to a high-SEER model can save you up to 20% on energy bills over time. If you’re considering a system replacement, make the switch to the latest R-32 tech for maximum energy savings.
🧮 9️⃣ Climate Considerations — Adjusting Your System for Efficiency Based on Region
Understanding your local climate can help you fine-tune your system for optimum performance.
🌞 Moderate Climates
If you live in a place with warm temperatures (like California, Texas, or Florida), your R-32 system will operate most effectively with regular maintenance, minimal fan use, and smart temperature settings.
