Performed ac maintenance. Came across some issues with 2017 Ameristar 4 ton single stage system. No float switch, capacitors getting below tolerance and high starting amps. Homeowner elected to make preventative repairs today. Installed ss1 float switch, explained if drain clogs up, thermostat will go blank. Installed turbo200x on outside unit. Turbo mini for indoor blower. Also installed 4 ton start assist kit. System cooling at this time, let homeowner know to order the 20x30x1 air filter online because it’s a unique size. System cooling and operating better than I got here.
