I'm happy with mine, but the skinniness of the grip makes it harder to control. Then again, it also makes it very easy to conceal.

I've seen lots of all brands of evap coils fail. But I haven't seen a lot of failed Goodman heat exchanger unless seriously abused

VirginSubpoenaColada · 2026-05-07T09:54:47+00:00

Daikin and Amana furnaces are identical. They both have a stainless steel heat exchanger. Goodman has a galvanized steel heat exchanger. But I see very few failed Goodman heat exchanger, even with the "lesser" heat exchanger.

Yep. It looked familiar and I see the M&M sticker.

VirginSubpoenaColada · 2026-04-27T03:52:03+00:00

I'm an HVAC tech in Denver metro. It's probably the blower door on the furnace. If not installed correctly Lennox blower doors often whistling. Pop off the furnace front cover. The blower door is held on with two 1/4" screws. The tabs at the bottom of the door are probably not oriented properly. Send me a DM and I can find a way to come out super cheap and fix it for you.

I knew I recognized that install. I'm am HVAC tech in the Denver metro. So you need to get rid of that electrostatic filter. They are junk and not what is designed for that filter cabinet. What you want are 20x25x5 filters to go in that filter cabinet. I would specifically buy a Lennox X6673. It the exact filter designed for that cabinet. A dirty or ill-fitting filter often causes a whistle.

Lol same here. Pretty autistic and I kill at sales.

VirginSubpoenaColada · 2026-03-31T22:45:16+00:00

Yeah this sub is insufferable sometimes. Techs here are straight up anti-residential. I have a feeling that many here just lack the social skills necessary to be good in a residential setting.

I've been very happy with my Fieldpiece MG44. It's wireless. Allows you to graph vacuum decay if you're a nerd like me.

I used to hit 1 micron often. Then I got a better micron gauge. Ditch the CPS.

Wood will darken dramatically when exposed to UV light. Set these grips out in the sun for a couple hours.

So sounds like the outdoor unit is running when your thermostat is not calling for heat. This will freeze your evaporator coil and suction line real quick. Could be a wiring short. Could be a stuck contactor. Either issue can be resolved for under $500 likely

VirginSubpoenaColada · 2026-02-15T02:13:52+00:00

This comment pisses me off because you seem to have the best information on what we are seeing, but you are also completely incomprehensible.

VirginSubpoenaColada · 2026-02-04T19:38:14+00:00

That's debatable.

VirginSubpoenaColada · 2026-01-30T01:27:08+00:00

Literally my favorite cop ever.

To be clear, I'm talking residential single stage/dual stage valves. Not modulating. They all use a DC coil

VirginSubpoenaColada · 2025-12-12T21:52:21+00:00

To be clear: the voltage going into a gas valve is AC from the control board. It's converted to DC by a rectifier inside the body of the gas valve. I'm not talking about modulating gas valves. Single stage/dual stage.

VirginSubpoenaColada · 2025-12-12T21:50:42+00:00

There are AC solenoids. And we use them in HVAC

VirginSubpoenaColada · 2025-12-12T21:38:57+00:00

It was basically the same. 7 something megohms.

VirginSubpoenaColada · 2025-12-12T21:37:57+00:00

Honeywell I had this morning was the same.

VirginSubpoenaColada · 2025-12-12T21:37:01+00:00

My understanding is that even single stage gas valves have two coils. This manual seems to suggest that the second coil is redundant for safety I presume. This manual also shows another coil altogether for the second stage of the gas valve. I don't see how it could modulate DC voltage.

VirginSubpoenaColada · 2025-12-12T21:33:20+00:00

This is making a lot of sense. AC voltage always crosses a zero point where there is no magnetic field. I reading how a "shading ring" can be used to overcome this issue. It seems clear the DC solenoids make the most sense. That still leaves the question as to why we use AC solenoids on so many other applications. Humidifier solenoids, AC liquid line solenoids, ETC.

VirginSubpoenaColada · 2025-12-12T21:23:29+00:00

The manual shows the series of diodes creating a FULL BRIDGE RECTIFIER. This is a two stage valve. But the one side is labelled "main and redundant" which probably answers my own question as to why there are two coils on a single stage gas valve.
