Tune up suwanee. Completed tune up. Found blower and coil clean. Flame sensor and ignitor clean. Inducer motor is running high amps and could burn out. Capacitor for blower is very weak and needs to be replaced. Combustion is good. Air flow is good. Coil does have rust and corrosion on it indicating copper thinning. System has no secondary water safety to protect furnace from water damage or surge protection or indoor air quality.
