Review on 🔍 Manometer - RISEPRO Digital Air Pressure Meter and Differential Pressure Gauge - HVAC Gas Pressure Tester by Tres Carmon

A very inexpensive way to measure duct pressure in an HVAC system. (Be sure to get a set of probes as well) This simple and inexpensive pressure gauge has solved a longstanding problem with our furnace. Our oven overheated and shut down and the service technician didn't know why. Was it a problem with the furnace, the duct, the coil? I used this gauge to measure the supply and return pressure and found that they were too high compared to the oven spec. It turns out that our house was previously remodeled and a large stove was added without expanding the air ducts. Thus, the existing air ducts were not sufficient to move the amount of air expelled from the large furnace, and it overheated and was blocked as a precaution. I added and lengthened ducts to bring the print closer to spec and now the oven works. great and the house warms up much more evenly. This manometer provided important information to understand what was going on and what to do about it. Excellent investment!
