Diagnosed Bryant 925SA furnace with intermittent operation. Found corroded flame sensor causing improper flame rectification (0.5 microamps measured). Replaced sensor and verified proper signal at 3.2 microamps. Also discovered partially blocked condensate trap causing pressure switch to open during operation. Cleaned trap, verified proper condensate drainage, and measured draft inducer vacuum at -1.2 inches WC. Advised homeowner on importance of annual maintenance and proper humidifier settings during spring transition.
Investigated a heat pump that wasn’t providing enough heat. Discovered a clogged air filter restricting airflow and causing the system to overheat. Replaced the filter and cleaned the evaporator coil. Checked the refrigerant levels and ensured proper defrost cycle operation. The heat pump is now running efficiently with consistent heating output.
