Buying Guide: Key Purchase Considerations
- Coil type compatibility: Evaporator vs. condenser coils may require different cleaners; check whether a product is labeled for evaporators, condensers, or both.
- No-rinse vs. rinse-needed: No-rinse formulas offer quicker turnaround for busy HVAC setups, but some applications may still benefit from light rinsing.
- Foam action and contact time: Thick foams improve dwell time on grime but require careful application to avoid overuse.
- Dilution controls: Sprayers with automatic mixing (like Coil Cannon) ensure consistent concentration, reducing waste and user error.
- Safety and compatibility: Look for corrosion inhibitors and NSF registrations where applicable, especially for systems near food areas.
- Environment and odor: Citrus scents and neutral formulations can help with indoor air quality considerations.
