They arrived on a Sunday and fixed the issue in 20 minutes!
Diagnostic service call on 2003 WeatherKing furnace. System is triggering rollout switch. Had over 4,000 ppm in flue. The heat exchanger failed due to indoor coil being so caked up that the coil would freeze thaw and then run into the heat exchanger causing massive amounts of rust and weak spots eventually causing a significant crack in exchanger. Heat exchanger is under warranty.
Upon arrival I found a 1988 Lennox overheating due to heat exchanger being compromised. Customer is going on vacation to Las Vegas for a week and will make a decision after they get back. Recommend replacing unit asap. Will write up estimate on a 80% and 90%.
During investigation found that the blower cap has exploded and coated the low voltage wiring with oil from capacitor on a Carrier furnace.Also found blown 5 amp fuse and a blown primary transformer. Checked blower winding, windings on blower motor are going out. The way the furnace is currently, can not diagnose any further problems until current issues are fixed.
