In an aspect, an HVAC system includes an inducer motor to provide combustion airflow, and a pressure sensor to measure an output airflow pressure of the inducer motor. The HVAC system may initiate the inducer motor, and receive a pulse width modulation (PWM) signal from the inducer motor, wherein the PWM signal indicates a PWM signal of the inducer motor corresponding to a predetermined airflow pressure of the inducer motor and measured by the pressure sensor. The HVAC system may compare the PWM signal to a baseline value, and control the inducer motor based on the comparing of the PWM signal to the baseline value. The HVAC system may also generate a status notification of the combustion airflow of the HVAC system in response to the comparing the PWM signal to the baseline value.

A system faults to a return air sensor integrated within a heating, ventilation, and air conditioning (HVAC) unit. The system transmits a signal to a remote sensor. The system determines that a return signal is not received from the remote sensor. The system obtains a temperature reading from the return air sensor. The system determines whether the temperature reading satisfies a temperature setting stored in the memory. In response to determining that the temperature reading does not satisfy the temperature setting, the system enables heating or cooling of the HVAC unit until the temperature setting is satisfied. In response to determining that the temperature reading satisfies the temperature setting, the system disables heating or cooling of the HVAC unit.

The present disclosure provides systems, apparatuses, and methods for monitoring building efficiency by a heating, ventilation, and air conditioning (HVAC) system. In an aspect, an HVAC unit including a memory and a processor coupled with the memory is disclosed. The processor may be configured to establish a current building efficiency state value of a current run cycle of the HVAC system. The processor may also be configured to determine an building efficiency state deviation value based on a difference between an average building efficiency state value of a set of previous building efficiency state values and the current building efficiency state value. The processor may further be configured to determine whether the building efficiency state deviation value satisfies a building inefficiency threshold. The processor may also be configured to provide an indication including an inefficiency status to a device associated with the HVAC system based on a determination that the current building efficiency state satisfies the building inefficiency threshold.

A flame sensor for a furnace of a heating, ventilation, and air conditioning (HVAC) system includes a sensor body and an electrically conductive member of the sensor body. The electrically conductive member is configured to be disposed within a flame region of a burner of the furnace and configured to receive electrical current from a controller of the furnace. The flame sensor also includes an anti-oxidation coating disposed on an outer surface of the electrically conductive member and configured to transmit the electrical current from the electrically conductive member. The anti-oxidation coating is configured to contact a flame produced by the burner and expose the electrical current to the flame.

The present disclosure relates to a gas valve assembly for a furnace. The gas valve assembly includes a gas valve including an inlet flange having an outer geometric profile and defining a gas inlet of the gas valve. The gas valve assembly also includes a bracket having a mounting panel, a first support flange, and a second support flange, where the mounting panel extends between and is integral with the first support flange and the second support flange. A slot is formed in the first support flange and defined by a portion of a perimeter of the bracket. The outer geometric profile of the inlet flange corresponds to a profile of the slot, and the slot is configured to receive and abut a portion of the outer geometric profile. A passage is formed in the second support flange and configured to receive a gas flow from the gas valve.

Embodiments of the present disclosure are directed to a furnace that includes a blower configured to operate to force a fluid through the furnace, a motor having a rated speed, in which the motor is coupled to and configured to actuate the blower, and a controller configured to receive data indicative of an operating characteristic of the furnace and regulate operation of the motor to be at or below an operational speed limit. The controller is configured to set the operational speed limit based on the data indicative of the operating characteristic of the furnace, such that the operational speed limit is less than or equal to the rated speed of the motor.

A furnace system includes a burner assembly configured to generate combustion products within a primary combustion zone comprising one or more burners. The furnace system includes a panel disposed downstream of the burner assembly along a flow path for the combustion products, where the panel includes at least one panel opening. The furnace system also includes a secondary combustion air gap defined by one or more spacers disposed between the burner assembly and the panel, such that a secondary combustion zone is established between the burner assembly and the panel and/or downstream of the panel. The secondary combustion air gap is downstream from and external the burner assembly.
