Hey there!
I’m Mike Sanders, your go-to guy for no-nonsense HVAC advice. Today, we’re diving into R‑32 systems—better for the planet, better for your wallet. This page gives you everything you need: from install prep to hands-on troubleshooting. And don’t worry—I’ll include extra resources links along the way. Let’s get started!
🔧 1. Why Go R‑32?
-
Higher efficiency = lower bills: R‑32 offers better heat transfer and lower GWP than R‑410A.
-
Rebate-ready: Many utilities offer incentives once you install certified systems.
-
Simple footprint: Fewer components, fewer headaches.
🔧 2. Pre‑Installation Checklist (Revised)
-
Sizing matters: Use a reliable BTU calculator to get the right tonnage for your home’s square footage.
-

-
-
Electric prep: R‑32 systems often run on 208/230 V—verify your panel and breaker match the unit specs.
-
Ventilation needs: Double-check clearance around the condenser and air handler to ensure proper airflow.
-
Permits & codes: Always check with your local building department. Some towns require permits—even for homeowner DIY!
📦 3. Step‑by‑Step Installation Guide
Mike’s Straightforward Process—now with a real install video!
-
Unpack & inspect: Check line sets, handles, and panels. No bent fins or missing nuts.
-
Mount the outdoor unit: Place it on a solid level pad, away from debris and vents.
-
Install the air handler: Connect refrigerant lines, use nitrogen purge, bleed properly.
-
Wire it up: Install a 208/230 V disconnect, follow the wiring diagram, and ground it correctly.
-
Evacuate & charge: Pull vacuum, ensure deep pull, then charge per R‑32 specs—not R‑410A!
-
Startup & performance check: Run for 30 mins, then take superheat, subcooling, airflow, and ΔT readings.

🔍 4. Troubleshooting Hub
Common issues and fixes:
-
Low airflow?
⁃ Dirty filter? Replace or clean it
⁃ Blower speed? Adjust fan settings
⁃ Duct obstructions? Inspect supply runs -
No cool air?
⁃ Refrigerant leak? Contact a certified tech
⁃ Inverter malfunction? Check fault codes
⁃ Sensor misread? Inspect coil probe -
Odd sounds or vibrations
⁃ Loose mounting screws? Tighten 'em
⁃ Fan motor wobble? Replace bearings
⁃ Refrigerant pulsing? Adjust TXV
👍 Pro tip: Always check your error/fault history—most R‑32 units show errors in digital displays.
🔁 5. Maintenance & Seasonal Checks
-
Clean coils, change filters, inspect condensate lines, and test defrost sensors.
-
Document cooling capacity in spring, cleanup in fall.
