What does everyone thing about Economizers?

[jrmech]

they are wonderful, they do not only do free cooling but constantly replace stale air in a building.

majority are not working because people have no clue on how they operate, so they just close off the dampers, jumper y1 to 2 and call it a day.

If you're a service tech never stand by a big RTU with an open economizer and smoke a doobie. Especially when it's at a parole office. Many years ago a top tech I knew did just that. Busted! (and fired)

That office must have looked like a Cheech and Chong movie....

Depends on the brand. If it's a a York I probably worked right for a year. Now if it's a Lennox I love them.

Other than that they are used a lot here as a source of makeup air. So it's important to keep them working

They are CLIMATE DEPENDENT.

Honestly if you one in my neck of the woods you know someone got shafted and sold an economizer that they'll never use.

Economizers are a great option if they are maintained. I usually find the screens plugged with dirt and the control boxes home to hornets or bees. Thats how i found out what a good bee killer coil cleaner is.

They make us a lot of money. Those motors are EXPENSIVE!

I found two on a roof recently that were installed so when the motor actuator was energized, it tried to pull the already closed dampers "more closed."

We'll work on that problem this fall, when they can really take advantage of the cool air.

I could go either way but I sure wish plumbers would take their vents higher when it's obvious what's going to sit on that curb next to it. Too often I have to stick a tall piece of PVC pipe over the little stub they left to keep the economizer from pulling in bathroom odors.

Very true

100% of new calls on roof tops the economizers do not work... and 100% of the time customer will not repair due to cost..... makes sense to have an economizer in Winnipeg as 40 below gives you ample free cooling

That's funny. I had a guy that smoked cigarettes and could not understand why I got upset when he'd pull the panels off a r/t unit and light up. I told him the smoke goes to the office and upsets tenets.
After he quit smoking , he understood.
The orginal controller by Honeywell was a problem. The sensor was horse hair or mylar and had a habit of failing in about a year. Pricy too. Glad to see solid state.
