FAQ:

Q: Do I need a hard start kit for my AC?

A: You should consider installing a hard start kit if you find yourself in one of these scenarios: If your air conditioner is already hard starting, you should contact a professional ASAP to investigate the problem. “How do I know if my AC is hard starting?”

Q: Do all single phase ACS have a hard start?

A: In the past, most single-phase ACs came from the manufacturer with built-in hard start devices, but many newer AC models don’t include a hard-start kit. If your air conditioner doesn’t have a built in hard start kit (your technician will let you know), you should consider having an AC professional install one.

Q: How do I know if my air conditioner is hard starting?

A: If you hear a stutter or clicking noise when you turn on your AC, and your AC doesn’t stay on for long, then those are signs your air conditioner is hard starting. Contact a Phoenix AC professional if your air conditioner/heat pump is hard starting. It could cause serious damage to your cooling system, so you should get it fixed ASAP.

Q: How does a hard start kit work on a compressor?

A: And if your compressor is already worn out, it requires even more electricity to get it to shift from “start” to “run” mode. That’s when a hard start kit saves the day: A hard start kit shortens the startup period of the compressor and reduces the amount of electricity it takes to start your AC.
