A compressor that struggles to start is telling you something. Here are the five signs a hard start kit will help — before a hot day turns into a no-cool call.
1. Your lights flicker when the AC starts
That dip is the compressor pulling hard to get going. A hard start kit gives it the torque to start fast and clean.
Furnace Direct · Factory-Direct Pricing
Why pay a contractor's markup?
Buy the same name-brand AC system the pros install — shipped factory-direct to your door. No middleman, 5-star rated, and financing available.
Hesitation at start-up is strain on the motor windings. Reducing it extends compressor life.
3. It struggles on the hottest days
High head pressure makes starting harder right when you need cooling most.
4. The system is older
An aging compressor has less starting torque than it used to. A kit gives it a boost.
5. Long line sets or low voltage
Both make starting harder. The RectorSeal Kickstart T05 fits single-phase 1–3 ton systems at 208–265V.
Buy the genuine part. We ship authentic RectorSeal, factory-sealed, with the full manufacturer warranty — not the counterfeits flooding marketplaces. Nationwide shipping with tracking.
