Installed on my 9-year-old 3-ton Carrier AC. AC showed 83 amps startup before installation. First start with EasyStart was 33 amps, and by the sixth start, it was down to 21.5 amps and whisper quiet!
I'm glad to have found this product on RVupgrades, not just because of the competitive price, but to support a company directly rather than through Amazon!
Wish I would have bought this sooner. Went from 110 amps startup to 28 amps. Makes startup of compressor completely smooth..
No, installing the Flex-Soft Starter will not void your AC manufacturer's warranty. It actually helps protect your equipment by reducing strain on the compressor and electrical components. Many HVAC professionals recommend soft starters for system protection.
With the Flex-Soft Starter installed, most 2-3 ton residential AC units can run on a 3000-3500W generator. For larger 4-5 ton units, a 4000-5000W generator is typically sufficient. This represents a significant reduction from the 6000-8000W generators normally required.
Most homeowners with basic electrical knowledge can install the Flex-Soft Starter in 60-90 minutes. We provide detailed step-by-step instructions, wiring diagrams for common AC models, and installation videos. If you're not comfortable with electrical work, any HVAC technician can install it in about 30 minutes.
