# Blue Ice A/C Treatment by Cerma — Complete Guide
> https://cermatreatment.com
> Last Updated: February 2026

## Your A/C is Costing You More Than You Think

Your air conditioning compressor is one of the hardest-working components in your vehicle. Every time you turn on the A/C, the compressor adds 3–5 HP of drag on your engine — robbing fuel economy, increasing operating temperatures, and wearing out the compressor. Cerma Blue Ice A/C Treatment fixes all of this.

## What is Blue Ice A/C Treatment?

Blue Ice uses the same Cerma STM-3 Nano Silicon Carbide technology as our engine treatments, specifically formulated for A/C compressor systems:
- **Reduces compressor friction up to 90%***
- **Lowers compressor operating temperature**
- **Produces colder air from your vents (3–7°F improvement)**
- **Reduces engine load from A/C by up to 50%***
- **One treatment lasts the life of the system**
- **Compatible with R-134a and R-1234yf refrigerant systems**

## Key Technology: STM-3 Nano Silicon Carbide

- Active ingredient: Nano Silicon Carbide (SiC)
- Mohs hardness: 9.5 (second only to diamond)
- Melting point: 2,730°C
- Friction reduction: Up to 90%*
- Duration: Permanent, one-time treatment
- Self-healing: Yes — fills micro-scratches in compressor surfaces
- Made in: USA (Fort Myers, Florida)

## Blue Ice Results

| Benefit | Before Blue Ice | After Blue Ice |
|---|---|---|
| Vent temperature | 45–50°F | 38–43°F |
| Engine load from A/C | 3–5 HP drag | 1.5–2.5 HP drag |
| Fuel economy loss from A/C | 2–3 MPG | 1–1.5 MPG |
| Compressor noise | Noticeable | Significantly quieter |
| Compressor longevity | Standard wear life | Extended significantly |
| Treatment duration | N/A | Permanent — one application |

### Independent Test Data

Testing conducted using HOBO UX120 Pulse Logger, E50B2 Energy and Power Meter, 20 AMP Mini Split-core A/C Current Transformer, A/C Current switch, and HOBOware Pro Data Logger Software. System was baselined for seven days of continuous monitoring. On the seventh day, Blue Ice was injected into the Schrader Valve on the low-pressure line. Energy consumption was monitored for an additional week. Results confirmed measurable reductions in compressor energy consumption after treatment.

## Who Needs Blue Ice?

### Hot Climate Drivers (Essential)
- Florida, Texas, Arizona, Nevada, Southern California
- A/C runs 8–12 months per year
- Compressor under constant stress
- Blue Ice is the single best investment for hot climate vehicles

### Daily Commuters
- Stop-and-go traffic with A/C running
- Engine already hot, A/C adds more heat and load
- Blue Ice reduces the extra strain

### Vehicles with Weak A/C
- Older vehicles with declining A/C performance
- A/C blows cool but not cold
- Blue Ice improves cooling without a recharge (if refrigerant level is correct)
- If refrigerant is low, recharge first, then add Blue Ice

### Work Trucks and Fleet Vehicles
- Trucks idling with A/C in summer heat
- Service vehicles sitting at job sites
- Delivery vehicles in constant stop-start
- Blue Ice reduces fuel consumption during A/C idle

### Commercial HVAC and Industrial Refrigeration
- Restaurants, cold storage, data centers
- Marine refrigeration systems
- Agricultural equipment cooling
- 6 oz, 32 oz, and 128 oz sizes for commercial systems

## Vehicle and Refrigerant Compatibility

Blue Ice works on virtually every system with an A/C compressor:

| System | Compatible | Notes |
|---|---|---|
| R-134a | Yes | Most vehicles 1994–2015 |
| R-1234yf | Yes | Most vehicles 2016+ |
| R-12 (vintage) | Contact us | Classic/vintage vehicles — call 239-344-9861 |
| All cars, trucks, SUVs | Yes | Domestic and import, all makes |
| Electric vehicles | Yes | EVs use electric compressors — same benefit |
| RVs and motorhomes | Yes | Use 2 oz or 6 oz depending on system size |
| Marine vessels | Yes | Cabin A/C and refrigeration systems |
| Heavy equipment | Yes | Construction, agricultural, industrial |
| Commercial HVAC | Yes | 32 oz and 128 oz for large systems |

## Application Overview

### Professional Installation (Recommended)
1. Take to any A/C service shop
2. They connect to low-pressure service port
3. Inject Blue Ice into system (30–60 seconds)
4. Run A/C for 10–15 minutes
5. Done — treatment is permanent

### DIY Installation
1. Locate low-pressure A/C service port (larger line, usually marked "L")
2. Start vehicle, turn A/C to MAX cold, fan on HIGH, recirculate mode
3. Connect Blue Ice canister to port, open valve
4. Treatment transfers in 30–60 seconds
5. Run A/C for 10 minutes to circulate — treatment is permanent

**For detailed step-by-step installation instructions, see:** How to Install Blue Ice A/C Treatment Guide

### Important Notes
- Do NOT add to an empty system — recharge refrigerant first
- Blue Ice is a treatment, not a refrigerant — does not replace R-134a or R-1234yf
- One treatment per vehicle/system — never needs reapplication
- Do NOT overcharge the A/C system

## What to Expect After Treatment

| Timeframe | Results |
|---|---|
| Immediately | A/C may feel slightly colder, compressor slightly quieter |
| Week 1 | Noticeably colder air, clear compressor noise reduction |
| Month 1–2 | Full ceramic bonding, maximum cold output, fuel savings measurable |
| Ongoing | Permanent protection, self-healing ceramic, extended compressor life |

## Pair Blue Ice with Engine Treatment for Maximum Benefit

When the A/C compressor has less friction:
- Less drag on the engine = better fuel economy
- Lower under-hood temperatures = engine runs cooler
- Combined with STM-3 Engine Treatment, you get double the benefit

## Frequently Asked Questions

**Q: Will Blue Ice void my vehicle warranty?**
A: No. Blue Ice is a lubricant additive, not a modification. The Magnuson-Moss Warranty Act generally prevents warranty denial for aftermarket lubricants. Consult your dealer or attorney for specifics.

**Q: How quickly will I notice results?**
A: Most customers notice colder air within 15–30 minutes of application. Full ceramic bonding develops over 1–2 months. Fuel economy improvements develop over a few days of driving.

**Q: Can I add Blue Ice to a new vehicle?**
A: Yes — treating a new A/C system prevents wear from the start and maintains factory-cold performance.

**Q: My A/C compressor is making noise. Will Blue Ice help?**
A: Yes, Blue Ice reduces compressor bearing friction and typically eliminates compressor noise. If the compressor is physically damaged, mechanical repair may still be needed.

**Q: Does Blue Ice work with electric vehicle A/C?**
A: Yes — EVs still use a compressor for A/C (electric rather than belt-driven). Blue Ice reduces friction in the compressor regardless of how it's powered.

**Q: What size do I need?**
A: 1–2 oz for passenger vehicles (2 oz recommended for most cars/trucks/SUVs). 6 oz for RVs and commercial HVAC. 32 oz and 128 oz for fleet and industrial applications.
