I came across a video that said not to use greater than a MERV 10 air filter on HVAC system, as it said you could damage it if air flow becomes restricted when dirty resulting in a high pressure drop.

I cannot square how or what would be damaged. The motor amp draw will actually drop from less fan air mass, although I dont think the ODP motor winding cooling would be affected either as it is not in the HVAC air flow stream, I dont think. Even if TEFC motor. Even said youcould damage the evaporator, but really since there is less air to be cooled, the refrigerant would not absorb as much heat load as it should. Now obviously the system would not be as efficient as it would need to run longer for same effect, leading to reduced life cycle, but that isnt ”damage” in my mind.

Now I have seen compresor pumps fail as you increase the pressure ratio on the pump. You pull a greater vacuum on the inlet side with a normal discharge pressure, no different than raising the discharge pressure above the design. Pressure is heat, hence valves and such can fail. But in this instance, we are not considering a mechanical pump, just a fan, which is really a pump in itself. Surely they are not talking “damage” to a fan. But then again, it does increase the pressure ratio, or does it if it is pulling less amps?

Things to ponder. Guess I will go MERV 8 and call it a day.

Not as big a deal in the winter, but in the summer it can cause your A-coil to freeze up and it will start collecting H2O in the bottom of the air handler. This happened to me on a split system. Not sure if it will do the same on package unit. I use an 8 merv now. In place of the higher merv you can install a UV dust particle eliminator.

Wouldnt the hot gas bypass valve regulate the refrigerant so it doesnt freeze?
nm really..no big deal and I was somewhat messing around. Thank you though..

The PF guys do a good job helping eachother out with stuff like this. Gramps would be proud. There is a lot of knowledge collected over the lifetimes of all the regulars to the PF and this thread. I am glad I can ask you guys stuff from time to time.

Its sad to see what some of the other forum threads have devolved into. Theres insane amounts of complaining and panic just because CJH and staff have been very selective in the portal this year, and dont have many holes to fill in the roster. People are complaining like we suck or something, and looking to argue about literally anything. We have won 30 games in the last 3 seasons ....and have more than 50% of our 83man roster bluechips (ranked Top300 in class) for the first time since Fulmer was coach. 16 out of 25 recruits in the 2025 class alone are bluechips. Wonder when all the Negas will figure out the reason we aren't chasing guys in the portal is because Coach is happy with the roster and we spent the bulk of our $$$ there? We lost zero players of consequence to other teams. This staff has made HS recruits and retaining guys the priority. We are gonna be young next year at WR, LB, Oline, and Dline...those are listed from most young guys to least...but have enough talent to still be looking at a 9-3 year IMO. In 2026 we should make the playoffs and have a good shot at a Title. Lots of freshmen and sophomores will get much needed experience in 2025. I am as excited as I have ever been about UT football and other sports. Some people will never be happy it seems.

I get my degree in Construction Science in the fall from UT. They've done a good job of preparing us for the Construction industry as well.

On Season 1 Ep 3 of American Premeval, and that woman being guided by dude to a town, is getting on my nerves..always getting them in trouble.

Yeah shes not a good listener 😄. Sara is a good woman though. Isaac Reed (the guy that saved and guides her and her son, and 2 moons) is the Boogeyman though. Good at killing bad people, and using whatever he can get his hands on...

Wife: On the way home from her gym calls me and asks "Do you need anything from the store to make breakfast."

Me: "Yes. Sausage, bacon, and Honey Nut Cheerios."


She walks in the door with "healthy" Cheerios, oatmeal, a variety of hot teas, and yogurt.


Going to be a great weekend

Moral of the story...

Go get the stuff yourself instead of asking.

You may come out of it healthier and that will help prolong the longevity of your life with her.
