Compressor Start Assist: What Is It and Why Your HVAC System Needs It?
At Reeis, we understand that your HVAC system’s compressor is the heart of your air conditioner or heat pump, responsible for circulating refrigerant and ensuring your home stays comfortable. However, starting up the compressor can place a significant strain on your system, especially in older units or in extreme weather conditions. A compressor start assist is a valuable upgrade that can enhance performance and extend the life of your system. But what exactly is it, and how does it work? Let’s dive in.
What is a compressor start assist?
A compressor start assist is an electrical component designed to give your HVAC compressor an extra boost during startup. It consists of a start capacitor and a potential relay, which work together to momentarily provide additional power to the compressor, helping it start more efficiently.
How does an HVAC performance start assist work?
When your air conditioner or heat pump turns on, the compressor requires a surge of energy to begin operation. A start assist kit reduces the strain by:
- Delivering a temporary high-voltage boost to the compressor.
- Allowing the compressor to start faster and more smoothly.
- Reducing the wear and tear caused by hard starts.
Once the compressor reaches its normal operating speed, the start assist disengages, and the system continues running as usual.
Signs your HVAC system may need a compressor start up capacitor
If your HVAC system struggles to start or exhibits any of the following signs, a compressor start assist may be a beneficial upgrade:
- Frequent tripped breakers – A struggling compressor can cause electrical issues.
- Loud startup noises – A hard-starting compressor may make loud clicking or humming sounds.
- Delayed or failed startups – If your system takes longer than usual to start or doesn’t start at all, it could be due to a weak compressor.
- Older HVAC systems – Aging compressors often require additional support to function efficiently.
Benefits of installing a compressor performance boosting kit
- Extended Compressor Life – Reduces wear and tear, preventing premature failure.
- Lower Energy Consumption – Reduces the initial power surge, improving efficiency.
- Improved System Reliability – Helps prevent startup failures and unnecessary service calls.
- Enhanced Performance in Extreme Weather – Ensures smooth startups even in hot or cold conditions.
Risks of not installing an air conditioner start assist kit
If your HVAC system struggles to start without a compressor start assist, you may experience:
- Increased strain on the compressor, leading to early failure.
- Higher energy bills due to inefficient startups.
- Frequent system breakdowns and costly repairs.
Reduced comfort as your system struggles to maintain temperature.
Is a compressor start assist kit right for your HVAC System?
While not every HVAC system requires a start assist, it is particularly beneficial for older units, systems with long refrigerant line runs, or areas with frequent power fluctuations. If you’ve noticed any of the warning signs above, it’s worth having a Reeis professional assess your system.
Final thoughts on the hard start kit
A compressor start assist is a simple, yet effective upgrade that can improve your HVAC system’s performance, efficiency, and longevity. If your system shows signs of hard starts or inefficiency, installing a start assist may help prevent costly repairs and ensure reliable operation.
