proactive or not? should I replace the attic fan at the same time when replacing the roof?

they replace the roofs in our home owners association. These units are 30 years old. I have an attic fan (they call it "Power Vent") which is probably also 30 year old, and comes on when temperature exceed a set limit.

The cost to replace or install a new fan is $235 while on the roof

The cost to replace a power vent retroactive is $340

These do not include the electrical connection, they say I need to call an electrician to do that, but the wires are right there and I think I can do it myself.

While my fan works, it is old and noisy. I am tempted to install a new one, unless the general wisdom says they don't build them like they used to do and the old one will probably last even longer than a new unit. what do you say?

If it's 30+ years old, I would replace it. The price difference alone would get me on board.

Connecting would be easy peasy as long as you remember to cut the juice before doing the connections.

Your HOA may not allow you to make the electrical connections out of concern for fire safety.

I'd replace it without a thought.

Not even a 2nd thought- probably even get some additional payback/savings in energy consumption. Gotta believe efficiency has improved over that time span.... and better to replace proactively than have it fail, have the higher cost to replace then + other cost impacts during period where you don't have that heat venting.

I would replace the 30 year old fan without hesitation.
It's spinning on borrowed time as it is.

Might be a good time to get higher airflow, or to get a very quiet one.

Technically an attic fan is a large fan, like a box fan or even larger, mounted in the wall with the flow directed outside. Ours has louvers that more or less keep the inside air, inside, when the fan is off.

It is turned on manually in the evenings, and the windows elsewhere in the house are opened. The fan sucks hot air out of the house and cooler air in through the open windows. Ours has a countdown timer as a switch, so it automatically turns off after an hour.

It puts out quite a breeze and does a nice job cooling the house down quickly after a hot day. It also removes evidence of cooking snafus relatively efficiently.

When we had our house re-roofed and re-sided last year, the contractor asked if we wanted our attic fan removed completely. It's certainly less necessary when you have air conditioning, but no way did we want to get rid of it!

I think he has a roof vent fan. Not a whole house fan.
Save a few bucks at roof replacemnt by not duplicating staging, crew labor and reflashing the fan.

Swap it out. I tried to keep an old fan limping along ( and successfully inhaled a lot of vaporized lead when re welding what turned out to be a crappy solder job .. oh ! My brains !). It was a wasted effort.

That is whole house fan. An attic fan vents the attic and hopefully, if sized and vented properly, will keep the attic and roof cool. Unless the attic fan can keep the attic roughly the same as the outside temp, in my opinion, it and the intake vents, are too small.

My attic fan has a temp and humidity sensor. Turns on at 85 degrees, or at 80% humidity. There are times in the spring and fall where it is 100% humidity and foggy. The fan can run for days, moving moist and foggy air through the attic. I have a manual power switch to shut it off during these times.

Replace with roof. Becomes part of the tax deduction.

Thanks folks, will go ahead and replace it. I think they install whatever fan they chose, same for all units, I don't know whether I can ask for a more silent model. I don't have time to shop for one.

you could likely reduce the noise with isolation washers when you mount it.

Likely a little lower leak risk if done with the re-roof rather than later on.

I mounted mine with some 3/8" silicone foam pads. between the mounting tabs and the stringers.
