A method for evaluating a heat exchanger of an air conditioning system includes measuring a pH level of a condensate of the heat exchanger and determining a condition of the heat exchanger in response to the pH level.

System and method for identifying clogged evaporator coil

Aspects of the invention are directed to condensate traps having a back portion and a front portion. The back portion includes a first passage enclosed between the first wall, a second wall, and a back wall. A first opening in the back portion connects the first wall and the second wall with a first float placed over the first opening and does not travel below the first opening and is prevented from leaving the first passage by a first constriction. The front portion of the condensate trap includes a second passage enclosed between the third wall and the fourth wall. A second opening connects the third wall and the fourth wall in the front portion and a second float is placed below the second opening such that it does not travel through the second opening and is prevented from falling below a predetermined level by a second constriction.

Condensate trap

A furnace with a condensing heat exchanger and a pH sensor, and a method of monitoring the furnace are provided. The furnace may include a condensate collector box and/or a condensate trap. At least one of the condensate collector box and/or the condensate trap may include pH sensor (e.g., disposed within the respective component). The pH sensor is configured to measure a pH level of the condensate from the condensing heat exchanger. The furnace may include a control board configured to receive the pH level from the pH sensor. The control board may be configured to trigger a notification and/or change the operation of the furnace (e.g., to dilute the condensate) based on the received pH level. The notification may include at least one of: an illumination of an indicator disposed on the furnace, and a transmission of a signal to a communicating device such as a thermostat.
