Introduction: Why Efficiency Matters with Your HVAC System
Your Goodman heating and cooling system already delivers a solid balance of performance and value—but are you getting the most out of it? Whether you’ve recently installed a new unit or are maintaining one you’ve had for years, small tweaks and upgrades can help your system work smarter, not harder.
This guide dives deep into the best ways to maximize energy efficiency with your Goodman system—using smart thermostat settings, filter maintenance, and ductwork optimization. Whether your goal is lowering energy bills, improving indoor air quality, or extending system lifespan, we’ve got you covered.
1. Filters: The Unsung Hero of HVAC Efficiency
Why Filters Matter
Your air filter isn’t just about catching dust—it’s a frontline defense for your HVAC system. Dirty or clogged filters:
-
Restrict airflow
-
Make your blower motor work harder
-
Lower SEER2 efficiency
-
Can lead to frozen coils or short cycling
How Often Should You Change Your Filter?
-
Standard 1-inch filters: every 30–60 days
-
High-MERV filters (11+): every 3–6 months
-
Homes with pets or allergies: monthly changes recommended
Tip: Goodman systems work best with MERV 8 to MERV 13 filters. Anything higher may restrict airflow unless your ductwork is specifically sized for high-resistance filters.
Smart Filter Maintenance Hacks
-
Set a recurring calendar alert to check your filter monthly
-
Write the install date on the filter edge with a marker
-
Consider a reusable washable filter (but clean it thoroughly every 30 days)
2. Smart Thermostats: Better Control, Lower Bills
Is Your Thermostat Helping or Hurting?
Manual thermostats are functional—but they can’t adapt to your schedule. Upgrading to a Wi-Fi or programmable thermostat (like the Honeywell T6 or ecobee Smart Thermostat) gives you the power to automate efficiency.
Recommended Settings for Efficiency
-
Summer cooling: 76–78°F when home, 82–85°F away
-
Winter heating: 68–70°F when home, 62–65°F away
-
Use the “auto” fan setting to avoid continuous operation
Goodman + Smart Thermostat Compatibility
Most Goodman systems (especially newer SEER2-rated units) work with:
-
Nest (Learning & Thermostat E)
-
ecobee (SmartThermostat, Lite)
-
Honeywell (T5+, VisionPRO)
-
Emerson Sensi
Installation tip: Always verify your Goodman control board has a C-wire or use a C-wire adapter.
3. Ductwork Hacks: Airflow Is Everything
Leaky Ducts = Money Out the Window
According to ENERGY STAR, homes can lose up to 30% of conditioned air due to duct leaks. That means your Goodman system might be working harder just to cool your attic or crawlspace.
How to Spot Duct Problems
-
Hot or cold spots in your home
-
Weak airflow from certain vents
-
Higher-than-expected energy bills
-
Visible gaps or damaged insulation on ducts
Efficiency-Boosting Duct Hacks
-
Seal leaks with mastic sealant or metal foil tape (not duct tape!)
-
Insulate ducts in unconditioned spaces (attics, garages)
-
Have a pro perform a Manual D duct test to check sizing and airflow
4. System Settings That Boost Performance
Fan Mode: On vs. Auto
-
AUTO (recommended): Fan only runs when heating or cooling is on
-
ON: Runs 24/7, improving filtration but increasing electricity use
If you’re using high-efficiency filters or trying to boost IAQ, ON mode can help—but watch for higher energy usage.
Compressor Delay Settings
Some Goodman thermostats support “compressor delay”—a feature that keeps the fan running briefly after the compressor shuts off, helping to:
-
Pull out remaining cold air from the coils
-
Boost dehumidification
-
Improve efficiency with no extra strain
5. Coil and Condenser Maintenance
Clean Coils = Better Heat Transfer
Dirty indoor (evaporator) or outdoor (condenser) coils reduce your system’s ability to absorb and release heat—making it less efficient and overworked.
Annual maintenance checklist:
-
Shut off power
-
Rinse the outdoor condenser with a hose (avoid pressure washers)
-
Use coil cleaner on evaporator coils if accessible
-
Remove leaves, debris, and weeds around the outdoor unit (at least 2 ft clearance)
6. Other Tips That Improve Efficiency
Zoning Systems
If you have a multi-level or large home, adding a zoned control system can significantly reduce energy waste. Goodman systems can integrate with basic zone dampers and multi-zone thermostats.
Ceiling Fans Help, Too
Use ceiling fans in the summer (counter-clockwise) to distribute cool air more evenly—allowing you to bump the thermostat up 2–3°F without feeling a difference.
Use a Dehumidifier
High humidity makes you feel warmer. A standalone or whole-home dehumidifier can reduce the load on your AC during muggy summer months.
7. Bonus: When to Call a Pro for Efficiency Gains
Sometimes DIY tips aren’t enough—especially if your system is:
-
Over 10 years old
-
Frequently short cycling or freezing up
-
Using R-22 refrigerant
-
Showing signs of undersized ductwork
A Goodman-certified HVAC technician can:
-
Perform a full system audit
-
Check refrigerant charge and airflow
-
Recommend duct resizing or SEER2 upgrades
-
Help determine if your system qualifies for 2025 energy tax credits
Conclusion: Small Changes, Big Impact
Getting the most out of your Goodman system doesn’t always mean replacing parts—it means optimizing what you already have. By paying attention to filters, thermostat settings, ductwork, and seasonal maintenance, you can reduce your utility bills, improve comfort, and extend the life of your system.
