AG3000 HVAC Surge Protector With TPMOV Technology
The AG3000 HVAC Surge Protector by Hliay offers comprehensive surge protection specifically designed for HVAC systems. It features triple protection covering line-to-ground (L-G), line-to-line (L-L), and line-to-neutral (L-N) surges. This surge protective device uses TPMOV technology to effectively guard against dangerous power surges that might otherwise cause costly damage.
The unit is enclosed in a waterproof casing suitable for outdoor installations and includes an LED indicator that monitors the protector’s status, providing instant visual confirmation of protection activity. A 5-year warranty is included, underscoring its reliability and manufacturer support.
BXST 140J Surge Protector Voltage Protector Plug
The BXST 140J is a compact surge protector designed for home appliances including refrigerators and air conditioners. This plug-in device cuts off power automatically when voltage exceeds safe limits, preventing damage from both overvoltage and undervoltage situations. It features adjustable settings accessible via buttons to tailor high and low voltage protection thresholds, as well as delay time settings, enhancing its adaptability across different devices.

A key feature is its 3-minute delayed compressor start, preventing damage caused by rapid cycling when the appliance attempts to restart post-power outage. This delay increases the lifespan of connected HVAC units and prevents unnecessary breakdowns.
EIIDAR HVAC Surge Protective Device for Indoor/Outdoor Use
The EIIDAR surge protector focuses on controlling instantaneous overcurrent and voltage bursts, protecting HVAC equipment from damage caused by sudden surges and lightning strikes. It supports line-to-line (L-L) and line-to-neutral/ground (L-N/G) protection methods.
The device is suitable for both indoor and outdoor installations featuring simple wiring. It has a clear double green LED indicator design for easy status monitoring, helping users quickly verify protection functionality.
Buying Guide for Air Conditioner Surge Protectors
Type Of Protection
Look for surge protectors that provide multi-mode protection such as line-to-ground (L-G), line-to-line (L-L), and line-to-neutral (L-N). Comprehensive protection modes cover the most common and dangerous surge pathways in HVAC wiring.
Surge Absorption Capacity
Higher surge current capacity (measured in kiloamps) means better protection. Devices with a 20kA capacity or greater handle larger power spikes and tend to last longer during multiple surge events.
Voltage Range And Adjustability
Voltage protective settings should cover the expected operating envelope of your home power system. Products with adjustable thresholds allow customization to match local voltage conditions and appliance sensitivities.
Delay Start Feature
A delay in the compressor’s restart post power outage helps prevent damage caused by rapid cycling, a feature especially useful for air conditioners and refrigerators.
Installation Location And Weather Resistance
For outdoor HVAC units, choose surge protectors with waterproof and flame-retardant enclosures (e.g., IP65 rating). Indoor units can opt for smaller, less rugged designs.
Status Indicators
LED indicators provide real-time feedback on the device’s operational status, allowing users to confirm protection without complex testing.
Warranty And Support
A multi-year warranty (typically 3 to 5 years) and responsive customer service add value, providing peace of mind and protection against potential defects.
Compatibility
Ensure the surge protector’s amperage and voltage ratings are compatible with your air conditioner model and local electrical standards.
