Had this issue on a job. Polarity was fine, board was not functioning properly and needed to be replaced. Thanks for the help!

Really helpful video! Thanks.

I find myself in need of a new furnace...my old Trane has a cracked heat exchanger. You have answered many of my questions in a manner that I could understand. I do have another question. If I go to a two stage gas furnace and lock it into second stage, how should the tech be evaluating the compatibility of my existing duct work? My house is about 1650 square feet and my old 120,000 btu 80 percent furnace did well. I really appreciate your help!!

Is there any way to hook up a kill switch or shut off rather than just turning the fuel off?

What do use to clean the burners?

ANDY,GOOD INFO. THANKS

Got that problem on an air temp furnace

Everyone should run the numbers. For me, I would likely never recoup the cost of a 90%+ furnace. The cost savings isn’t there. The fact they have more parts that can fail is another issue on top of not getting the money back.

Iam owning a HVAC Company with 1 employee. I make 220.000 Euro a year. I do heatingpumps, oil heating systems and ACs in germany. I have permissions for 2 bigger cities for working on natural gas heating systems. Also i do jobs for both cities. Actually our hourly rate begins at 78,50 Euro exkl. salestax. People call me after they fired their hvac guy.

I dont know how this video came up i was watching how to fix a HDMI on a xbox but watched it anyways

What state are from? When temperature is at 0 F (outdoors) a chart says you cant go over 25% humidity inside? Is this accurate?

I have a issue of a gas furnace throwing a reversed polarity code, and my polarity is exactly like it needs to be occording to your video what could be my issue?

EXACTLY 😎🤟

Didn't fix my issue. Still flashing same codes. I have no multi meter.

About to go try this right now because that's the code mine is throwing.

Just had a Lennox installed through Costco in Orange County - we are very happy - customer service was great even after installation for return follow up work that needed to be addressed

My furnace the vents has been blowing out cold air last couple days, maintenance was here all day yesterday trying to fix it but they didnt vents are bloing out cold air as I type this and its 8 degrees outside. I have it set at 72 and its reading 67. Should I call a company that gives free quotes

Grandaire 1 stage $8k VS Goodman 2-stage $10k…….. thoughts in FL?

For the house what can you run on this?

dude thank you so much for this video. i just froze my ass off for the night

The reason it died on initial start up is that you forgot to turn off the choke, I believe.

Not a valve change, just the actuator.

Great video!! Just a quick question would 2 stage be better for a house which has less optimal insulation? Parts of the house has cold spots and half of the second floor is above garage and is usually colder during winter and warm during summer. Any thoughts?

Get a drill that fits the holes and clean them up

Hi Andy, I have a problem with my furnace in that the main squirrel cage fan is moving in a very strange jerky fashion and it will not come up to speed. Could that kind of behavior come from reversed polarity? I tried to do your tests but mine was different. The leads were covered in plastic boxes. I was also wondering if I just tried to swap those 24v wires and it doesn't fix it, could that damage the circuit board further?

This is the stupidest video I’ve ever wasted my life watching. Are you trolling? Yeah no shit working 90 hours a week will get you more money. we want to know how to earn more money because we are slaving away making $18 an hour

Thank you so much. My family now has heat tonight. Thank you

Thanks for your video! I have a situation like this now: gas valve doesn't open when ignitor glows, there is voltage less then 1v send to gas valve. When I start to check the voltage on the transformer, it suddenly starts to work (gas starts to burn), but it will fail again after half a day. Has been like this in the past 2 days. The error code is 6 flash (Trane XL80): 115 VAC power reversed polarity or poor grounding. I replaced the control board a few years ago myself, can't remember for what reason.

Got a brand new Lennox stage 2 furnace installed. At high output (is that stage 1?) it makes this annoying high pitched noise through the ducts. I don't know what to call it; sound resonance? I'm so disappointed because it's louder then my old furnace at. Maybe it's blowing too hard through my ducts? Should/can I reduce the speed of a blower somewhat? Maybe by 15%. I live in Canada. Winters can be vicious so I'd still like to retain furnaces' ability to power up when needed. Any input would be appreciated.

It won't damage embroidery?

Wrong, many models are exactly the same except longer warranties are priced higher…. Different model numbers with different prices and warranties. Bad deal…. Bad business practices…

Boom! Fixed first try on the new control board. Thank you!!!

Now it makes Sense since you put it that way... Thank you Man 👍👍

Dumb question but realistically how did the voltage get reversed in an existing furnace? Reason I ask is I just replaced my motor ECM and it's reversed.

Información muy útil. Gracias 👍🏼

Higher efficiency often means sacrificing longevity.

Good video.... i have one on getting into hvac on my channel as well

I have an idea to turn a psc motor into a psuedo variable speed motor. It would require 2 relays and a timer. When you get a Y call for cooling, the Low speed tap will be energized for 2 minutes. After 2 minutes, a relay will kill power to relay energizing the Low speed tap and switch it to the normal high speed tap for the remainder of the call for Y. I figure this set up will dehumidify better and also keep the evap coil from freezing by only allowing the Low speed for 2 minutes. Thoughts?

Is this something an HVAC tech would be willing to do ? Seems like 90percent of HVAC companies want to only push new units. It’s disgusting what that industry has turned into. I’m in the Memphis area and it’s shameful. I did manage to install a new Control board after being quoted $1,000.00 by a local HVAC guy. Now there is a flashing code for reverse polarity and I’m nervous about attempting to remedy it myself.

RHEEM

Got quotes of 5 ton Day n Night 14.5 SEER HVAC system, all 3 were Elite Dealers, the $11,000 one has suspended license, 2nd one is licensed and is family business, cut from $16;000 to $12,500, same equipment, 3rd one is licensed and also family run, very honest guy, $9,500, he came with a team of 7 including himself, replaced the system with new condenser, evaporator, gas furnace, Wi-Fi thermostat, same model number and equipment as the other two, did all the details as stated on other 2 quotes in less than 3 hours, very efficient, very clean, the system is running perfectly., he registered the system for warranty right away, I got the warranty certificates via email the same night. This is in LA, you need to do lots of research and get many quotes.

I keep my water heater OFF except when i take a shower. saves $20-25/month.

I've been in my new place for a year. I spent a few months planning. I replaced the 20+ year old A/C+furnace with a cold climate heat pump. I replaced the original aluminum clad windows and sliding doors with new Andersen ones. That alone cut the heating used by 70%! I had the loose blown attic insulation removed and added 4 inches of closed cell spray foam changing the attic to conditioned space. I changed the old gas hot water tank with a instant electric hot water unit. The attic doesn't warmer than 90 even in Arizona summers. In the past winter, it was reaching 100 in February. I updated all the electrical to meet the 2017 NEC or later swapping out every switch and receptacle. And this before I install a solar+battery system.

Just in time for thanksgiving

What about ground level crawl space 18 " height. Cooling not needed, heat only 4 months max per year.

Calibrate / Adjust your hygrometer with a saturated-salt test in a ziploc: kosher salt in a dish with a bit of water in it, put it in a ziploc, put your hygrometer in that bag, 24 hours later, it should read 75.0%, if not, adjust your hygrometer; of that hygrometer can not be adjusted to match 75%, discard it.

For nostril/sinus dryness/bleeds : put some olive oil on a Q-Tip .. and you know what to do next, I am sure.

Good video thanks!

What is a reasonable price for new duct work? 10 runs (10ft-30ft each). 2000 sq ft ranch, single story, AC in attic center of the home.

Im a truck driver at the moment but Am looking at Going into HVAC thanks for the video’
