I just had a new 80% furnace installed last year. It replaced my old one made in 1957. It was rusted bad leaking carbon monoxide. I was going to go with a 90+ furnace but the replacement parts cost $1000 or more, like the circuit boards. I bet the new furnace does not last that long. The new ones are made out of thinner steel, so you have to buy a new one ever 10 to 15 years.
Excellent information. I have a question though, when the heat leaves the ductwork when the fan stops, it has to go somewhere, so it must transfer through the walls of the duct into the confines of the building somewhere, so it's not really completely wasted, is it?
I watched a few videos done by you, however unfortunately could not find one on the 59 series carrier. Could you load one showing, removing, cleaning & reinstalling the burners? on 59 series carrier. Thanks
He forgot to mention HE furnaces are expensive to repair and prone to fail earlier then simple single mid efficiency ones.Mid blower fan around 300-max 500 HE 1k-1200 that's just the blower.So you saved money on gas then once something goes wrong pay back all the savings plus more.Most HVAC tech use simple furnaces in their own houses.
Only expensive to repair HE furnaces and Air Conditioners if they are more than one stage and more than one speed! You can get single stage, single speed HE furnaces and air conditioners! They will last longer given the simple controls, motors, and simple valves. If you get units that are more than one stage, thats where the parts become more expensive and less reliable! Plus dual and variable stage systems might be quieter when operating on low, but when they do ramp up during extreme temps to full capacity, they are louder and more prone to break down due to the more sensitive parts like inverters, modulating gas valves, and vfd drives that are under higher stress due to them having to be built for single phase power give residential single family homes are only single phase serviced power! Single stage systems don’t need vfd’s modulating gas valves and inverters to operate, just relays and contactors!
Great video. Can this system be controlled by a person that is not living in the unit? Like a building manager? My furnace flames goes out and when I complain they come back on. Very strange.
Have a over insulated row house with a 80% gas 35 year old furnace that on coldest month cost less then $115 including gas stove water heater & gas dryer Been trying to get my mom to replace her huge gravity feed gas furnace that is 65 years old. She had 1 service call in all that time ( bad thermostat ). Know somebody that had a gas furnace that used a power pile thermostat. Best thing it having no 120 or 24 foot power will run during a power failure. Great vid.
In a high efficiency furnace (2 pvc pipes) is the combustion process completely sealed and separated from the air that mixes into the home? I ask because a new Radon mitigation install has the outflow pipe outside the home within a couple feet of the intake pipe to the furnace.
If the furnace has two pipes (combustion air intake and exhaust) and is properly installed, then yes; you are not mixing the combustion process with house air. Combustion air comes from outdoors and combustion fumes are exhausted to outdoors. Your radon vent should terminate above the eaves.
@@HollisBrown thanks for the reply. In Canada, certain zones (mine included) you can't terminate the radon vent above the eaves due to extreme temperatures. It has to be terminated within inches of the exterior of the home. Otherwise they completely ice up.

Where can I find the video he mentions they would discuss later about exhaust/venting?

That is the problem with efficiency. It's expensive.

True but your lungs are irreplaceable. Better of spending money for potentially better air quality if a heat pump isn’t an option.

That would depend on the thermostat. Many modern thermostat can be remotely controlled.

I am very interested in your Mom's gravity furnace. Can you DM me a pic?

@@c.a.n.4202 O - Good to know...
That Radon exhaust tube should go all the way up to the roof line and a few feet above
@@Kiddro22 see my reply from a year ago
Nice video thank you so.much
