Description
The Packard TQS41 is a combination relay and capacitor hard start kit engineered to dramatically improve the startup performance of single-phase air conditioning and refrigeration compressors. By integrating both a start relay and a start capacitor into one compact assembly, the TQS41 delivers a powerful torque boost at startup — reducing the time the compressor spends in the high-amperage locked-rotor condition and relieving stress on the entire electrical system.
Hard start kits like the TQS41 are a go-to solution for compressors that struggle to start, especially on low-voltage circuits, long line sets, or aging equipment. The combination design simplifies installation by eliminating the need to source and wire separate components, making it a reliable choice for HVAC/R technicians in the field.
Key Features
- Combination design integrates start relay and start capacitor in one unit
- Boosts compressor startup torque for faster, more reliable starts
- Reduces locked-rotor amperage draw to protect wiring and contactors
- Ideal for low-voltage conditions, long line sets, and aging compressors
- Compact assembly for straightforward field installation
- Compatible with single-phase air conditioning and refrigeration compressors
- Helps extend overall compressor and system service life
Applications
- Residential and light commercial air conditioning systems
- Refrigeration equipment with single-phase compressors
- Systems experiencing hard-start or no-start conditions
- Preventive maintenance upgrades on older HVAC/R equipment
Why Use a Hard Start Kit?
Compressors are the hardest-working component in any refrigeration or air conditioning system, and startup is when they are most vulnerable. A hard start kit like the Packard TQS41 reduces startup time and amperage, protecting contactors, capacitors, and wiring from premature wear. It is a cost-effective upgrade that pays dividends in equipment longevity and fewer service calls.
