Your 4-ton R-32 AC and gas furnace combo is designed for comfort and high efficiency, but getting the best performance (and lowest energy bills) requires a few consistent habits and setup strategies.
Here is Tony’s practical, no-nonsense guide on how to keep your system running at peak performance while saving money and protecting your investment.
🛠️ Thermostat Programming for Efficiency
✅ Set your thermostat to 78°F (26°C) in the summer when you’re home, and higher when away.
✅ Use 68°F (20°C) in the winter while home, and lower while away or sleeping.
✅ Invest in a smart thermostat to adjust automatically and track usage.
Zoning tip: If you have a multi-zone setup, set unused areas a few degrees higher in summer or lower in winter.

🧊 Keep Filters and Coils Clean
✅ Replace filters every 30–90 days depending on pets, dust, and usage.
✅ Use MERV 8–13 filters to balance filtration and airflow.
✅ Clean the outdoor condenser coils at least once per season to maintain airflow.
Dirty filters and coils reduce efficiency and can increase energy usage by up to 15%.

🌬️ Maximize Airflow
✅ Keep vents and registers unblocked by furniture or rugs.
✅ Ensure doors between conditioned areas remain open for even airflow.
✅ Check that supply and return vents are free of dust.
Proper airflow reduces system strain, lowers energy bills, and improves comfort.
🌡️ Use Ceiling Fans and Blinds Strategically
✅ Use ceiling fans to circulate air, allowing you to set your thermostat a few degrees higher without sacrificing comfort.
✅ In summer, run fans counterclockwise to push cool air down.
✅ Close blinds and curtains during the day to reduce heat gain.
These small steps can reduce your cooling costs by up to 10%.

💧 Manage Humidity for Comfort and Efficiency
✅ Use your system’s “dry” mode if available during humid days.
✅ Keep windows closed during high humidity.
✅ Fix leaks that add moisture to your home.
Lower humidity levels allow your AC to cool more efficiently, making you feel comfortable at higher thermostat settings.
🧰 Maintain Proper Outdoor Unit Clearance
✅ Keep 2 feet of clear space around your outdoor unit.
✅ Trim back bushes and remove debris.
✅ Ensure the unit is level for proper drainage.
This ensures airflow and reduces strain on your system, enhancing efficiency.

🔄 Schedule Regular Maintenance
✅ Book annual professional maintenance for refrigerant level checks, electrical inspections, and burner cleanings.
✅ Keep a record of all maintenance to protect your warranty.
Preventive maintenance helps your system maintain 95%+ of its original efficiency over its lifespan.

💡 Upgrade for Efficiency
✅ Consider a smart thermostat to reduce energy waste.
✅ Use programmable zoning if applicable to reduce unnecessary heating or cooling.
✅ Ensure your home is well insulated to reduce system workload.
These upgrades can pay for themselves in 1–3 years through energy savings.
💰 Take Advantage of Rebates and Incentives
High-efficiency R-32 systems may qualify for: ✅ Federal tax credits under the Inflation Reduction Act.
✅ Local utility rebates for high-SEER systems.
✅ Special incentives for smart thermostat upgrades.
Check rebate eligibility on the DSIRE database.
