A hard start kit is a field-installed accessory that includes a start capacitor and a potential relay to give a compressor extra "torque" during startup. This is particularly helpful for older Mobile Home AC Condensers that may be struggling to overcome high pressures or low-voltage situations. By getting the motor up to speed faster, the hard start kit reduces the heat buildup in the windings, extending the life of your Compressor. It can also prevent your lights from flickering when your ACIq system kicks on. We recommend these kits for any system with long Line Set runs or those located in areas with unstable power grids. You can find universal and brand-specific kits in our Accessories-Kits collection. It is one of the most cost-effective ways to "save" a compressor that is starting to show its age. Adding a hard start kit is a proactive maintenance step that provides peace of mind during the hottest months of the year.
