⚡ Why We Installed a Hard Start Kit
Most homeowners have never heard of a hard start kit—but it can make a huge difference for an aging air conditioner.
On this 22-year-old system, the compressor was pulling 52 amps on startup, which is well above where it should be. Every time the A/C started, it put a huge amount of stress on the compressor.
After installing a hard start kit, the startup current dropped to 24.7 amps—cutting the starting load by more than half.
So what does a hard start kit do?
✅ Gives the compressor an extra boost when it starts
✅ Reduces the electrical strain during startup
✅ Helps older systems start easier, especially in hot weather
✅ Can extend the life of a compressor that's still in good working condition
It's important to know that a hard start kit isn't a magic fix for a failing compressor. But when used on the right system, it can reduce wear and help keep an older unit running longer.
If your air conditioner struggles to start, makes the lights dim, or is getting up there in age, it may be worth having it checked before it leaves you without cooling on a 90° day.
