About this product

A hard-start kit is cheap insurance for your AC compressor — it lets the compressor reach full running speed up to 10× faster on startup, reducing stress on the motor and extending compressor life.

What it does

A hard-start device is a capacitor/potential-relay combo that provides a burst of extra torque to the compressor at startup. This Kickstart T05 is OEM-approved by Ducane, Goodman, and York for permanent install in 1-3 ton single-phase AC and heat pump compressors (208-265V).

Why you'll want it

  • Extends compressor life — every startup cycle without a hard-start kit strains the motor windings
  • Cheap insurance vs. a $1,500-$3,000 compressor replacement
  • Helps units start cleanly in low-voltage conditions (brown-outs, long wire runs)
  • OEM-approved for permanent installation

Installation

Wired in parallel with the existing run capacitor by a qualified technician. Install time is typically 10-15 minutes. No modifications to the compressor itself.

Common questions

Is this needed on new equipment?

Not strictly — most new AC units start fine. But installers often add one anyway because it protects the compressor (the most expensive component) at a low upfront cost.

Will this void my warranty?

No. Kickstart is OEM-approved by Ducane, Goodman, York, and others. It's designed for permanent install.

What tonnage does this cover?

The T05 covers 1-3 ton (single phase) compressors. For 3.5-5 ton, use a different model — call us.

Common questions

Will it fit my unit?
It covers single-phase 1–3 ton AC, heat pump, and refrigeration compressors at 208–265V.

Is it genuine?
Yes — this is the genuine RectorSeal Kickstart T05 (96503), not a look-alike copy.

Does it ship nationwide?
Yes — we ship it nationwide with tracking.

Saved $2,400 vs local contractor

Got quoted $9,200 from a local HVAC contractor for a furnace replacement. Found Furnace Direct and got the exact same Goodman unit for under $5k delivered. My installer couldn't believe the price and installed it in one day. Runs perfectly.

Fast shipping, exactly as described

Ordered on a Tuesday, pallet arrived Friday. Unit was packed well, no damage, all factory sealed. Andrew answered my sizing question over the phone and got me the right model. Couldn't be happier with the purchase.

Installer said same one he'd buy at supply house

My HVAC guy said he pays basically the same price at his wholesale supply house. The markup contractors add is insane. Furnace Direct cut the middleman out entirely. Will recommend to everyone I know.

Heating my 2,200 sq ft home perfectly

Installed my 96% AFUE furnace a couple months ago. Heats my 2,200 sq ft home perfectly, and my gas bill dropped noticeably compared to the old unit. Great product, great price, great experience from start to finish.

Saved enough to pay for the install

Math was simple: 3 contractor quotes all over $8k. Furnace Direct plus local installer was under $5,500 total. Saved enough to basically pay for the install myself. Quality is identical to what contractors charge a fortune for.

No-pressure, honest pricing

Called a few HVAC companies first — every single one wanted to schedule an "in-home consultation" before giving me a price. Furnace Direct just showed me the price. Bought online, shipped next day, done. This is how it should work.
