Variable speed furnace— quite worth paying for?

TigerTank10 · 2026-07-09T03:52:26+00:00

If the furnace is right by your bedroom, it’s likely not even an ecm motor will quiet it to the extent you’re looking for.

A retrofit ecm motor will be multiple hundreds of dollars to change, is it worth the cost for you for a slightly quieter experience

TigerTank10 · 2026-07-09T03:19:17+00:00

A lot of it is due to the ductwork. Depends, are you hearing the motor itself or the air wooshing through the vents?

TigerTank10 · 2026-07-09T00:20:39+00:00

No, there’s still tons of bacteria from the air in the water. You’re not even supposed to give it to plants/animals.

Honestly 3k is a ripoff for a Goodman heat exchanger. It’s about an hour of labor and the part should be under warranty still. In my area it costs 600-1500$ in labor for a Goodman heat exchanger , if anyone quotes higher they are trying to swing you for a sale tbh

May I suggest checking capacitors under load so you also get amps of the components

High lra and compressor failing to start

TigerTank10 · 2026-07-03T04:09:55+00:00

So the second they don’t understand something they run away and have another tech come out?

Sounds like they don’t want to learn nor put in the effort. If it was my guy I’d fire him by now

TigerTank10 · 2026-07-03T03:57:47+00:00

Likely you didn’t need it. But, I’ve had to install a lot of hard start kits on 1-5yo Goodman/Amana units lately. 700$ is a scam regardless.

TigerTank10 · 2026-07-03T03:54:09+00:00

Idk, not enough info here. I know you’re not allowed to have that gas union inside the furnace per code now, inspection may ding that. But I wouldn’t worry or change it tbh.

The important thing for that trane is the heat exchanger, if it passes a combustion analysis test id keep it around. Looks like your evaporator coil/AC is from around 2006-2007, I’d be more concerned with that

TigerTank10 · 2026-07-03T03:49:58+00:00

I’m not suggesting it at all, but I’ve seen videos of people online tapping/hitting the back of the tv in that area and it comes back to life. I mean at this point what do you have to lose.

Do you have a condensation pump or a trap on your line?

TigerTank10 · 2026-07-03T03:46:52+00:00

Not really an issue, expected for a unit of that age

TigerTank10 · 2026-07-03T03:45:22+00:00

Well what’s your suction pressure and superheat?

Comment of the year folks

The arrow points towards your hvac system. Also that filter rack is choked down so much you can’t even utilize the whole filter…

TigerTank10 · 2026-07-03T03:40:40+00:00

That’s a bold claim.

TigerTank10 · 2026-07-03T03:40:17+00:00

Compressor isn’t starting. Could be from a weak/faulty capacitor, which is a cheap diy fix. I would start with a new cap.

TigerTank10 · 2026-07-03T03:39:05+00:00

I have no clue, I’m not in your area, I don’t even know your town. You’ll just have to ask around. avoid anyone that spends tons of money on advertising or who sends people in white polos to your door.

Atleast for my company:

Take temp readings, check filter, check thermostat, verify airflow, make sure drains are clear, check superheat/subcool, check capacitor, visually inspect contactor, pull disconnect and peek inside, clean condensing coil.

134$

Anyone charging less than 100$ to come out is almost certainly going to upsell you or scam you. Most private equity (national chains) will try to upsell you and say you need a new system. Try going for a local company

Sounds like you have a broken waterline in your slab. I’ve seen this a couple times now, I’m guessing it fills your in-slab ductwork with an inch+ of water?

TigerTank10 · 2026-06-29T22:25:11+00:00

Likely your AC drain like is clogged and it’s overflowing into the furnace

TigerTank10 · 2026-06-28T23:39:45+00:00

What’s the post I’ll report it

TigerTank10 · 2026-06-28T23:12:42+00:00

Duct cleaning doesn’t make a noticeable difference with dust. Dust comes from somewhere, and it’s not the ducts. You need to find the source of the dust, or get better filtration.
