1. What is R‑32 refrigerant and why is it preferred?

R‑32 (difluoromethane) is a single-component refrigerant with a Global Warming Potential (GWP) of ~675—about one-third that of R‑410A’s 2,088. As a result, it offers excellent cooling performance and lower environmental impact.

Its efficiency gains also reduce operating costs. According to the EPA’s SNAP program, R‑32 is an approved substitute refrigerant that aligns with new regulations favoring low-GWP options.

---

2. Are R‑32 systems safe to install and use in homes?

Yes—with conditions. R‑32 is classified as A2L, meaning mildly flammable. However, packaged units are factory-sealed, and certified HVAC technicians use the right equipment and safety protocols during handling.

Technicians must follow guidelines set by ASHRAE safety standards (details here: NFPA standards) and be certified under Section 608. Proper installation ensures no risk to homeowners.

---

3. How do SEER2 and EER2 ratings affect performance?

SEER2 (Seasonal Energy Efficiency Ratio) and EER2 (Energy Efficiency Ratio) tell you how efficient the unit is. With DOE updates, packaged ACs must meet at least 14.3 SEER2 and 11.5 EER2 to qualify for rebates and incentives.

R‑32 packaged units commonly range from 16–18 SEER2, translating to 20–30% lower operating costs than older R‑410A systems. ENERGY STAR certification further highlights efficiency and eligibility for savings programs.

4. What does proper installation of a packaged AC involve?

Installing a packaged unit is more than dropping it off your porch:

• Electrical prep – correct voltage and breaker sizing

• Placement – stable pad, clearance, drainage, and accessibility

• Refrigerant charge – precise R‑32 fill

• Duct or vent connections – sealed and sized for airflow

• Testing – amps, pressures, airflow, and thermostat settings

Following guidelines from the Department of Energy’s HVAC handbook (summary here: DOE maintenance tips) ensures proper installation and warranty validation.

---

5. Can I claim rebates or credits for buying an R‑32 packaged AC?

Absolutely. As of 2025, you may be eligible for:

• Federal tax credits up to $600 under the IRA (Form 5695)

• Utility rebates ranging from $200–$1,200 via Energy Star and state programs

• Combining incentives – stack local and federal offers for greater savings

The DSIRE database is your best tool to find local rebates. Always confirm eligibility by using your unit’s model number.

6. How long will my R‑32 unit last, and how do I maintain it?

Lifespan: 15–20 years, depending on lifestyle and care.

Maintenance basics:

• Monthly: Replace filters

• Seasonally: Clean coils, outdoor area, and inspect condensate lines

• Annual: Pro tune-up – test pressures, refrigerant charge, connections, and controls

According to ENERGY STAR, routine care improves system efficiency by up to 15%, increasing lifespan and preventing breakdowns.

7. What are common repairs—and what should I budget?

Realistic cost guide for U.S. homeowners:

• Compressor replacement: $1,200–$1,500

• Fan motor: $200–$300

• Coils: $500–$800

• Control boards or relays: $400–$700

When repair costs exceed 40% of replacement, it often makes sense to install a new high-efficiency unit—especially with current rebates.

---

8. Packaged unit vs Split system—what should I choose?

Packaged AC:

• All-in-one, outdoor unit

• Simple install, easier service

• Good for tight spaces or rentals

Split system:

• Compressor outside, air handler inside

• Better flexibility in installation choices

• Typically quieter and may offer higher efficiency

Choose a packaged system when space or simplicity is a priority—especially if you want faster installs and easier maintenance.

---

9. Are R‑32 units legal everywhere in the U.S.?

Yes—R‑32 use is approved by the EPA and not restricted by any state, including California. However, technicians must be certified, and installations must meet local building and electrical codes. Always verify contractors’ credentials for compliance.

---

10. What should I ask my HVAC contractor before buying?

1. Are you R‑32 certified and Section 608 licensed?

2. What are the unit’s SEER2/EER2 ratings and AHRI certification?

3. Do you handle all rebate paperwork?

4. Can I review your installation and service documentation?

5. What kind of maintenance plan can you offer?

A transparent contractor with clear answers is worth their weight in gold.
