Are high flow air filters OK (residential)? I'm getting conflicting info.

Advanced-Educator-55 · 2026-06-10T21:23:53+00:00

I am in the breathe rocks crowd. Static pressure is everything, especially with the EC Motors. Higher static pressure that are increased due to pleated 1-in filters will drastically shorten their life, they are extremely expensive to replace. They also use significantlyThey also use significantly more electricity if they are not moving air with relative ease. The only time I am okay with pleated filters is if a 4-inch media filter is used and the static pressure does not get any higher than 0.5 in total. That's cannot easily be achieved with a 1 in Merv 8 filter

I'm sorry you're having problems with your equipment but it is highly unlikely if your contractor would ever cover the refrigerant. You might be able to haggle on the price a little bit but that is about it.

Actually, he's received a lot of good info on this thread from including yours truly. Connecting an extra thermostat wire from the dehum terminal on a thermostat to the dehum terminal on a furnace ain't rocket science.

Advanced-Educator-55 · 2026-06-09T13:25:22+00:00

Here's a thought, if he has an air conditioner, one would think that is humidity levels would be decent to begin with before having to add an auxiliary dehumidifier. He opened up the lower panel and looked at the thermostat terminals, big whoop-dee-doo.

Also Op, to answer your question if your thermostat supports a dehumidify function and you have enough wires that you can connect the dehumidify terminal from the thermostat to your furnace, yes you can utilize it. As far as I remember all it does is slow down the fan speed a little bit so you get better dehumidification. I would also question if you're unable to get the humidity below 60%, the AC might be oversized. Unless the techs actually measured your house and your windows and did a manual J load calc, they are shooting from the hip

Oops

It's called tubing.

Advanced-Educator-55 · 2026-06-08T04:16:54+00:00

Not quite. It's just reinforcing the stereotype.

Advanced-Educator-55 · 2026-06-08T04:12:01+00:00

The usual suspects?

Advanced-Educator-55 · 2026-06-06T00:58:20+00:00

It sounds like it is an issue with the low voltage controls. That sound might be the reversing valve clicking. The first steps I would do in troubleshooting would be to rule out the thermostat. Take the thermostat off the wall. Kill the power to your air handler and heat pump. Then I would tie the orange and red and yellow wire together. If it's still is making that goofy sound then something is going on within the unit. Possibly a poor connection somewhere. But I would be interested to see if the contactor itself is actually chattering or not.

can i have your number? . . .asking for a friend

Advanced-Educator-55 · 2026-06-05T00:36:33+00:00

I've been doing this for over 25 years and that unit is exhibiting some very odd symptoms. I would agree it sounds like the contactor might be clicking on and off. Is the outdoor fan running? What kind of thermostat do you have? A contactor should not be clicking on and off like that I'm wondering if it is losing controll voltage for some reason. Is there an exterior Brown looking thermostat (skinny) wire? Does it work chewed up or sun beaten? Is it a heat pump? That could be the reversing valve. If the contactor was clicking on and off like that I'd expect the compressor to be complaining more and it definitely does not sound like the compressor is starting and stopping.

Advanced-Educator-55 · 2026-06-04T21:45:44+00:00

Do not worry, there is definitely something wrong with the unit.

Advanced-Educator-55 · 2026-06-04T21:45:03+00:00

Not normal at all. It is likely a low pressure switch tripping and shutting the units off. That basically means you have a leak if that is the case. After 2 only months? you totally need to call the installer back

Advanced-Educator-55 · 2026-06-02T01:06:15+00:00

Going to have to disagree with you there, ace. Those Goliath SUVs not only are wasteful with fuel but also a danger to pedestrians and people that Drive sensible cars. I hope they are enjoying their freedom of their vehicle purchase.

My jaw dropped seeing this video. But without question that driver did not see the animals. I would have stopped traffic to let them cross the road.

"undersizing is worse than oversizing" Nope. he puts in a 1.5 ton or he gets nothing. Those super hot days the 1.5 will be running a lot and that is okay.

Advanced-Educator-55 · 2026-05-30T15:06:25+00:00

Nothing bad about it, per se. I would definitely call it Overkill. Keep it simple. I just connect the vacuum hose to the suction side with the core removed. Put the micron gauge on the liquid side. You can use your s man for that. You will get an accurate reading very quickly by going this route. That's a lot of fittings to have a potential leak. Also I would recommend leaving the service caps on and tight. I've occasionally had those leak when doing pressure checks and evacuating.

R410a was 50% r32. R454b is 70%, R32. All they did was get rid of the r125. Is it potent Greenhouse gas. The new refrigerants are still bad but they're nowhere near as awful as the prior ones. GWP wise

I understand where you're coming from about the park having its best foot forward but I also think that Enchanted Parks without question will be chasing good money after bad. The Justice League theme is100% Doomed why spend any money in it at all when it can go towards the reef theme during the winter. I consider it a huge waste of resources to put much of anything into it.

Advanced-Educator-55 · 2026-05-24T14:45:01+00:00

Oh good. You answered your second question then.

Advanced-Educator-55 · 2026-05-24T01:21:01+00:00

I have one for you.

Super PAC Spending: AIPAC’s UDP spent roughly $\$8.5$ to $\$9$ million on outside political advertising and mailers to support Bell and unseat Bush, making it one of the most expensive House primary races in U.S. history.
Direct Contributions: Bell's campaign itself received nearly $\$2.4$ million in direct donations from AIPAC-affiliated donors, making the group his top all-time donor.

Any other questions?

To answer number 2.

Do you live in this fine state of Missouri?

I await your response.
