Choosing the right air comfort gear depends on the job. Do you need a sensor that lets an air conditioner adjust on its own? A control board for heating and cooling? A blower for a gas floor heater? Or a full kit to measure airflow and humidity across your home? The four products here cover those jobs, with prices from USD 91.67 to USD 1,119.35.
Quick take
The 390000453 SENSOR AIR is the entry point at USD 91.67 and focuses on temperature sensing. The 1173838 control board, at USD 249.97, is a drop-in replacement for regulating heating and cooling. The Williams 2102 blower, at USD 505.26, is designed to circulate heated air from vented gas floor heaters faster. The CPS ABMSTR kit, at USD 1,119.35, is the most comprehensive choice, with an air flow meter, temperature/humidity data loggers, a static pressure meter, and a carrying case.

- Control and regulation: 1173838 control board as a drop-in replacement for heating/cooling.
- Moving heated air: Williams 2102 blower for compatible vented gas floor heaters.
- Whole-home measurement: CPS ABMSTR kit for airflow, temperature, humidity, and static pressure.
Product notes
International Comfort Products 390000453 SENSOR AIR
The 390000453 is the lowest-priced product here at USD 91.67. It senses room temperature and adjusts an air conditioner's speed and intensity to maintain a comfortable temperature. That makes it a good match when you want automatic temperature response without paying for broader measurement tools. The trade-off is that its role is limited to sensing; the focus is narrower than the control board, blower, or balancing kit. If your existing system can act on a temperature signal, this sensor is a simple way to add that input.
International Comfort Products 1173838 Air Conditioner Control Board
The 1173838 costs USD 249.97 and regulates heating and cooling operations. It is a direct drop-in replacement for HVAC systems, and the listed safety features support equipment warranty. That makes it the most relevant choice if you need a new control board for an existing system. Its price sits between the sensor and the blower, so it is priced in the middle. The control board handles control and regulation.
WILLIAMS COMFORT PRODUCTS 2102 Blower,Circulate Heated Air 36FK85
The Williams 2102 blower costs USD 505.26 and is designed to circulate heated air faster throughout a room. It is listed as an accessory for free-standing vented gas floor heaters, with a voltage rating of 120V. If you have a compatible gas floor heater, this blower gives you a direct way to push warm air away from the floor. The limitation is that it is specific to vented gas floor heaters, so it doesn't cover central A/C sensing or general control-board work. It costs more than the control board but less than the full measurement kit.
CPS Products ABMSTR Easy-Hood Master Air Balancing/Comfort Kit
The CPS ABMSTR is the highest-priced product at USD 1,119.35. It includes an ABM-200 air flow/environmental meter, six TS-100 temperature/humidity data loggers, an SPM-K1 static pressure meter and probe kit, and a case. The listed capabilities include air flow velocity, air flow volume, dry bulb and wet bulb temperature, relative humidity, dew point, and more. This is the product for someone who wants a broad picture of indoor conditions across several locations. The limitation is the price: it's the most expensive item here by a wide margin, so it's a bigger investment than a single-room sensor or blower.
Final recommendation
Match the tool to the task. For the least expensive first step into automatic temperature response, go with the 390000453 SENSOR AIR. If your system needs a control board, the 1173838 is the part to compare. If you own a vented gas floor heater and want warm air moving faster, the Williams 2102 blower fits that scenario. And if you're ready to measure and balance the air across your home, the CPS ABMSTR kit gives you the broadest set of instruments at the highest price.
