Derek M. (California)

HVAC Contractor

I have put a few soft starts in before for customers who
have generator applications, but I just put this on my own home AC unit, and I am experiencing a quieter unit and seeing a monthly reduction on my utility bill every month during peak use. Incredible product!

Jeremiah F.

Maryland Homeowner

I have a 4-ton Amana and as our unit is getting older, it has gotten a lot louder. It’s right outside our kitchen window and next to our patio where we entertain. We’re so happy to have the SoftStart Home installed because it made our unit instantly quieter. We also have solar and are considering adding batteries, so our unit is now prepared for that as well.”

Kent H. (Texas)


I have a 3-ton Lennox AC that I installed the SoftStart
Home on. It was a quick installation, super easy to follow
the instructions, looks nice and clean, and I couldn’t be happier

By cutting the start-up amperage draw so drastically, you’ll notice…

  • Your A/C or heat pump starts and runs quietly, day or night.
  • No jarring thump or flickering lights when the A/C or heat pump starts.
  • The low-amperage start-up will extend your compressor’s life.
  • And no more low-power start-up problems during brown-outs, black-outs or emergencies by using a generator or battery backup.
