LF: Furnace replacement

[G-ZUS]

Any recommendations for a furnace replacement? My 43 year old furnace is starting to make all sorts of weird noises while running.

My mom used GI Joe and had really. Good things to say. She's a cranky old lady, and Jody took good care of her.

My personal recommendation is to get the lowest efficiency and lowest tech furnace you can.

Thank's, I have sent a quote request to them.

Are you selling anytime soon? If not, keep the furnace and replace the blower.

I had a house with a furnace of about the same age. Started making some noise, sourced a new blower for like $80 and put it in in about 30 min. Just food for thought.

Might be interested in your old furnace.

New blower motor like cjbair said and or bearings on a pulley and it'll be like new.

Just used Jody @ GI Joe a couple months ago. Good shit.

+1 for Advanpro, I've had really good experiences using them.

interesting thread. Is the general consensus that newer high efficiency furnaces are a lot more problematic than older ones? Just moved into a new place that has 29 year old furnaces and was planning to replace them in the next few years but now re-thinking this.

That's what I've heard. The older the better for reliability as far as I know.

Yea I’d see if you can find a repair person to fix it not someone that will just try to squeeze your wallet and sell you on a new unit.

Furnaces are stupid simple. If you can change your oil you can pretty much service anything on a basic furnace.

There is really nothing that can go wrong with your furnace that warrants a replacement other than the heat exchanger (and just in my experience due to the price and potential availability of an exchanger for your model) and even some of the leak tests techs do on them are snake oil. Since it’s making a noise it’s not the heat exchanger obviously so it should be a reasonable fix that you could probably do yourself.

May seem daunting but once you tear into yours you’ll be shocked at the simplicity

I have an older furnace (maybe 90s?) that's running a high voltage line to my thermostat. Do you guys have any recommendation for a guy they can come run some wires and turn it into a low voltage line so I can use smart thermostat like EcoBee or Nest?

I have two of these en route that i ordered by mistake (and company would not cancel the order):

Just looking for what i paid for it which was $110 CAD each after shipping/USD conversion.

I ordered them because i was told i had a millivolt system but turned out i had a standard 24V system. They should also work for a high voltage system too. It should be quite easy to wire in yourself and i could probably help you if you're not comfortable. Not an HVAC guy but learned a lot about these systems recently doing research. Basically you plug your high voltage lines into this box, then wire the lines going up to your thermostat into it as well. The smart thermostat will trigger the relay to turn on your high voltage system. This box also has a built in transformer that will give you a "c (common) wire". One issue is that you'll need 3 wires going up... if you only have two wires going up you can either fish a new wire up or use something like a 'fast stat common maker' which is basically a multiplexer. Nice thing about fishing a new wire is you can pull a 7-wire bundle up which will give you some extra wires that you can use for humidifier control.

EDIT: another option is to go with Mysa instead of nest/ecobee. Mysa works natively with line voltage systems

As long as natural gas prices remain this low, the pay back period on new HE furnaces will be decades out.

yep, keep the dinosaur as long as you can, mine's form the 70's, installed new in the house, only issues i have had is blower motors... new furnaces are very unreliable based on experiences with friends and family... keep the old one til the heat exchanger rots through... you'll never pay back the savings with an HE one because that money will go to repairing it.

possibly a dumb question, but if it gets to the point where the Heat exchanger starts cracking/rusting/rotting through, would that increase risk of a CO leak?

There needs to be a perfect storm of conditions before you have CO in your home. Crack needs to be exposed to airflow with a combination of a failed inducer blower. It's pretty rare, but it does increase the risk. Problem is most companies that find leaks won't work on the furnace anymore for liability reasons. It's also a wonderful scare tactic/sales tool.

Ah good to know. That’s one thing I’ve always been paranoid about with my older furnace even with two CO detectors in the house

No more than idling a car in your basement.
