This is a review of the Fan Handler model LA 277 fan speed head pressure control for air conditioners. Here is a buying link for the Fan Handler web site: www.fanhandler.com/index.php/... This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.

This works beautifully on my furnace. It keeps the air in my house moving very slightly and so when the furnace goes on you dont get a blast of cold air before the heat comes through the vents. It is also so quite you dont even realize it is running.

This type of Modulation, makes our home much more comfortable, and at the same time, our fuel bill has dropped ( : If we move, we are taking this with us!

Looks like a GOOD ONE IN YOUR TEST. I WOULD LIKE TO TRY IT. ESPECIALLY SINCE IT'S USA PRODUCT Good idea to use as a tool as well !!!!

Great review! I would think using thermal compound between the sensor and the liquid line would help it read more accurately and be more precise and responsive. Obviously insulating the temp sensor well is very important too.

You may be right. GFM

Seems to do the job and easy install. Thanks

Good information!! I like this idea better than an ECM motor personally. A little heat sink compound between the sensor and liquid line might speed up the sensors operation. Hope the knees are doing much better now

The compound may indeed help. I will be updating on the knee issue fairly soon. GFM

The sman's threw in the towel at the end there. They were like " No one needs AC in this weather , open a window please😢" . One question I have is how does it affect the temperature of the windings? They say >25% below fla causes excess heating in the windings shortening the motor life by 50%, but I would assume they are using pwm to control the fan speed in this case so that may not be an issue.
