Suncourt HC300 EQ2 Equalizer Register Booster  Product Reviews

"I purchased this item when we were having 110 degree F. air temp. in Arkansas and our A/C just couldn't cool our living room below 78 degrees F. The room has a cathedral ceiling and about 25 ft X 15 ft. Our general impression was that it helped somewhat - but did not make a remarkable difference. This could be b/c the heat was so extreme that nothing would have helped. Our A/C is practically new and works well, so I'm not inclined to blame it. I would predict that the smaller the room and probably one w/o a cathedral ceiling would be ideal for this product - it definitely brings the air up and out better. Also, if you live in an area with desert or tropical conditions where temps are extreme, you'll likely feel 'luke warm' about this Register Booster. For the money, I'd do it again. We'll continue to experiment with it - maybe putting it in different rooms to gauge it's effectiveness. But, I'd say that if you have a large area to cool (and you know you're A/C is working properly), you may wish to invest in a air flow booster that technicians place in your duct work."

"Based on the other reviews, it sounds as though the EQ2 works for some people and doesn't for others depending on their individual room and HVAC configurations. I have an upstairs room with a vaulted ceiling that is 10 degrees Fahrenheit hotter or colder than the rest of the house. The room is more than 200 sq. ft., has only one vent, and is the farthest from the blower. I've had my EQ2 now for 3 years and it is still working fine. The EQ2 brings the temperature difference down to about 4 degrees, which is livable. I tried out the AirFlow Breeze that has 2 DC fans in it but it didn't work as well as the EQ2."

"Like everyone else I have a room that doesn't get the benefit of enough heat. Is is fed by a side duct off the main furnace duct - really a bad design because the heat on its way up three flights races past this duct and even a scoop doesn't cure the 5 degree deficit. I put this fan over one of the two outlets for this side duct, AND BLOCKED THE OTHER to prevent the fan from just pulling air from the other vent. It now has to pull from the furnace and the 5 degree difference disappeared. It is also on a thermostatic control."

"This product does not do what it is advertised to do. I would never purchase again."
