Hey friends, it’s Savvy Mavi, and today we’re talking about something that doesn’t get nearly enough love: HVAC maintenance. If you’ve just installed a shiny new R-32 AC and gas furnace combo—or you're considering it—you’re probably thinking about comfort, energy savings, and maybe even tax credits.
But here’s the thing: even the best system needs regular TLC to perform like a champ year after year.
Let’s get into the must-do maintenance tips that’ll keep your system efficient, your energy bills low, and breakdowns at bay.
✅ 1. Change Your Filters—Seriously
This might sound basic, but I can’t overstate how important it is. Dirty air filters restrict airflow, reduce efficiency, and make your system work harder than it should. That’s a recipe for higher bills and early wear.
-
How often: Every 1–3 months, depending on usage and indoor air quality.
-
Pro tip: Set a recurring phone reminder—it’s that important!
🌀 2. Keep Your Outdoor Unit Clear
Your R-32 AC condenser (that’s the outdoor part) needs room to breathe. If it’s surrounded by leaves, weeds, or snowdrifts, it can’t properly expel heat.
-
Maintain a 2-foot clearance around the unit.
-
Rinse the coils gently with a garden hose every spring.
-
Avoid placing items like mulch or decor nearby that could block airflow.
📆 3. Schedule Annual Professional Maintenance
Even if you’re a DIY queen or king, you need a pro once a year. A licensed HVAC technician can:
-
Check refrigerant levels (especially important for R-32 systems)
-
Inspect electrical components
-
Clean the burners and heat exchanger
-
Test system performance and safety
Bonus: Keeping a regular service record may help preserve your warranty.
🔍 4. Inspect Your Ductwork
Leaky or poorly insulated ducts can waste 20–30% of conditioned air. That’s your money floating into your attic or crawl space.
-
Look for visible gaps or loose connections.
-
Feel for air leaks while the system is running.
-
Use foil-backed tape (not duct tape!) to seal small issues.
If your system feels weak or uneven, it could be a duct problem—not your AC or furnace.
🌡️ 5. Use Your Thermostat Wisely
Smart thermostats (which I highly recommend) offer features that support maintenance too:
-
Some alert you when it’s time to change your filter.
-
Others provide efficiency reports that help track performance.
-
Zoning systems allow you to use your equipment more efficiently and less often in unused spaces.

🌬️ 6. Listen to Your System
Unusual noises, uneven temperatures, or a system that’s running longer than usual are all signs something’s off.
-
Grinding or rattling may signal loose parts.
-
Hot and cold spots could point to airflow issues.
-
High humidity indoors may indicate your system isn’t dehumidifying properly (common in older units or undersized systems).
Catch small issues early, and you’ll avoid pricey repairs down the road.
🌎 7. Protect the Environment with Proper Refrigerant Care
R-32 is a more eco-friendly refrigerant with a lower Global Warming Potential (GWP), but like all refrigerants, it must be handled correctly.
-
Only certified HVAC pros should recharge or recover refrigerant.
-
If you ever notice an oily residue or hissing sound near the coil, shut off the system and call a technician. That could be a leak.
🔒 Final Thoughts from Mavi
I always say: comfort is an investment, not just a purchase. Your R-32 AC and gas furnace combo is already a step ahead in efficiency and environmental impact. Now it’s up to you to protect that investment.
A little regular maintenance goes a long way—and your system (and wallet) will thank you.
