It's cold INSIDE! | DIY gas valve change | Can I fix the furnace myself?!

[@fernandor1369]

HVAC tech here, looks good to me for a diy job. Only thing I would say is to have the gas pressure tested with a manometer to insure the correct pressure is entering and exiting the valve. Pipe wrenches come in handy when working on gas valves and lines.

[@craigbraswell4269]

Same as I was thinking. Also. He's lucky it's natural gas and not LP gas, or else he could really cause some damage without a manometer.

[@DadItYourselfDIY]

The HVAC tech that did my troubleshooting verification didn't say anything about a manometer. What is that?

[@fernandor1369]

[@DadItYourselfDIY]

Yeah?

[@danieltku]

Good video on replacing the valve. After seeing how it is done. I can decide whether to tackle this or call HVAC for a quote.

[@DadItYourselfDIY]

Exactly!

[@eastboundtrucking]

just wondering if you should check the outlet gas pressure on the gas valve?

[@DadItYourselfDIY]

The pressures were preset on the valve and marked. Seemed pretty straightforward. But I'll research that.

[@TheCowboysdude]

Should be testing both... to make sure that the inlet pressure is good as well.

[@DadItYourselfDIY]

@TheCowboysdude seems to be working perfectly.

[@craigbraswell4269]

If I were you, I would either call back the service company or invest in a manometer to check your 1st + 2nd stage manifold gas pressure to be safe. The factory will usually get pretty close, but sometimes it can be off by 30%.

[@DadItYourselfDIY]

Great advice.

[@toddm9501]

Just had this exact problem. $188 for the Honeywell gas valve which had to be shipped to our guy. And labor was $162. That was including the 3 days where he came out to diagnose. $375 total.

[@DadItYourselfDIY]

Not a bad price.

[@A_Well_Traveled_Man]

If that was my price, I would have taken that all day... Even though I know how to do it four hundred bucks, because he has the nanometer, and he could have checked it the meter itself and the dope that you would need to use.Would have justified it

[@DadItYourselfDIY]

[@craigbahruth]

Get a bench vise. Can have bolts with wing nuts, lock washers so you can install/remove vise when you need it. Just a idea 💡. 👊✌️

[@DadItYourselfDIY]

I need to get a permanent bench first!

[@StephenGertsch]

My furnace started to short cycle. It would fired up and run ~1 minute then would shut off only to fire up a couple of minutes later.. then repeat this cycle. Had a local HVAC tech come out to diagnosed the problem. He was almost sure it was a faulty the gas valve that was unable to "hold" the main gas solenoid open. He quoted $2500 to replace the gas valve and ignitor-pilot light assembly (which he said he always does when replacing a gas valve). I suspect his quote had more to due with the fact the furnace was 41 years old and he was more interested in selling me a modern more efficient model. The $2500 quote was his way of helping me do the "right" thing to replace a furnace that was well (+20 years) beyond its service life. I challenged the quote as being too high and he could not really justify the parts and labor costs. Went to my local appliance parts store and picked up a replacement compatible valve and new ignitor assembly; cost me $350. The original gas valve was a 5-wire model and the replacement was 4-wire. Fortunately the wiring diagram pasted to the inside of the furnace access cover was still readable. I was able to determine the 5-wire to 4-wire mapping. Hardest part was rerouting the existing pilot gas line to the pilot light gas port. Had to straighten, rebend sections and shorten the line to get it routed to the new location on the replacement gas valve. Needed to purchase a small diameter tube bender (Harbor Freight $10). Also needed to change a 3/16" spade connector to 1/4" spade connector on a one (exhaust air flow pressure sense) wire. Wife is happy furnace is working again.

[@DadItYourselfDIY]

You went a lot further than I would have! Bravo on your bravery and where with all!

[@TheCowboysdude]

2500 is VERY excessive... too much.

[@Username_87]

Sooo not DYI…😫thanks for letting me see what my furnace needs. At least I can just tell them what to replace versus them trying to sell me a whole new furnace. Mines only 3 years old.

[@DadItYourselfDIY]

I was willing to let them do all the work and pay for it. I just wasn't willing to wait an extra week for them to do it. You're going in with your eyes open!

[@snakeeyes1649]

HVAC technicians are like mechanics they take advantage of your ignorance and markup everything. It’s disappointing. As soon as people learn how to do things themselves, you see them posting hate. Kudos my friend!

[@DadItYourselfDIY]

Thank you for that. While I'm not an HVAC tech, I do have training in very similar systems.

[@techdaddy7955]

No we don't. Us techs don't make the pricing. We charge what our companies make us charge. You think we are out there to screw over the customers that keep us in a job? We actually think the cost of repairs we have to charge is ridiculous. At least us good techs anyway

[@DadItYourselfDIY]

@techdaddy7955 I agree, it was definitely his company. He literally told me how to fix it, saving a ton of money.

[@techdaddy7955]

@DadItYourselfDIY a good tech will do that. We would rather provide knowledge than anything. I've walked people through fixing thier furnaces over the phone on after hours just to try and save them the cost of after hours service call fees

[@DadItYourselfDIY]

@techdaddy7955 That's super cool!

[@brucezas1]

You're wrapping the tape backwards. Wrap it the same direction you screw on the valve which is clockwise in this case. Otherwise it can unwind when you screw it in.

[@DadItYourselfDIY]

It's confusing, but I got it right in the end.

[@MrJujubean]

I thought the exact same thing. Looked like he was unraveling the tape as he was tightning the valve plus he kept turning the gas valve back and forth as he was tighyning gas pipe.was pretty chincy with the soap bubbles too

[@DadItYourselfDIY]

@MrJujubean Doing my best out here. Thanks for watching. One year later, still works, no one has died.

[@bonobobros4960]

i hope someone can answer my question, my gas valve is bad on my trane xb, got an estimate for 650 installed but the estimate show 218 for a burner cover, what is that? is it a scam charge? 650 seems high but i'm not ready to do the dyi on this job . thanks

[@DadItYourselfDIY]

They wanted $800 to just do my valve, so the added parts and labor to do the burner cover seem about right for the market. Looks like the burner cover is a $100 part. images.app.goo.gl/r1YyrinuKXN1TVGy7

I did not. I don't have a "manometer"

[@jamesslagle6686]

I got sorta the same model, Brant's came out and told me it's gonna cost me $400+ parts, I've never tried to install one myself, But being a single income family of 4. I can't afford that. The part alone is only $130, The guy told me it would be around $300 for just the part... But it wouldn't be in until next week and then wouldn't be able to install it until next friday. But like I said I looked it up, Saw the part for $130. What should I do?

[@DadItYourselfDIY]

I ordered mine from Amazon and had it the next day. I cannot tell you what to do. If you are mechanically inclined, then it's something you can handle. If you are unsure about any of the steps, then ypu should let a professional do it.

[@elektrokinesis4150]

you should check manifold pressure to be sure you don't risk carbon monoxide, and also soot buildup which could mean a future heat exchanger replacement if it cracks from uneven expansion

[@DadItYourselfDIY]

Saw that in the comments. I have a manometer on the way. My furnace is out in the garage, so there is that.

@@DadItYourselfDIY it's probably within 10% of spec already, but its good to be safe

[@DadItYourselfDIY]

@elektrokinesis4150 Agreed!

[@DadItYourselfDIY]

@elektrokinesis4150 Is it standard or do I need to look in the manual for the inlet and outlet pressures?

[@elektrokinesis4150]

@@DadItYourselfDIY It should be written on the furnace unit in inches WC as manifold or outlet pressure, not to be confused with inlet pressure. If not then look in the manual. The reason why it needs to be adjusted is that natural gas is not always the same pressure or flow rate. Depending on the building and pipes used, you can have different amounts of restriction.

[@bighossirv868]

Did you adjust fuel at all

[@DadItYourselfDIY]

I did not. Went with factory settings and assumed the city meter is set to the correct delivery pressure.

[@johnthreadgill2843]

How much money did you save

[@DadItYourselfDIY]

I was quoted $600 plus parts to replace. The service call was $150. I bought the valve for $100 on Amazon Prime. So me doing it was about $250. Had I had them order the part and install it, it would have been, $150+$100+$600. So, I save $600 (assuming they didn't mark up the parts)

[@Shenmue06]

​@@DadItYourselfDIY $600 dollars for parts 😳!!! That's beyond ridiculous!! They were trying to charge you $600 dollars for a hundred dollar valve, some pipe dope and tape 🤦. Like seriously how do those people sleep at night when they're robbing people like that.

[@TheCowboysdude]

Well I see a few issues..... I'm glad you were able to fix it... but.. your connector inside that connects two pipes together should be a union... I wouldn't use just yellow gas tape... I'd use paste or both... that gas valve should ALWAYS be tested and testing to see if you have gas by unhooking the line...not a good idea... that's why we test inlet and outlet pressure directly on the gas value... ALWAYS. NOT really a wise idea this really isn't a DIY project... again, glad you got it working but I'd advise against doing this yourself unless you know what you're doing. Be careful tightening down your gas valve you could have stripped the threads...

[@DadItYourselfDIY]

Thanks for the advice!

[@frankjgornickjr3676]

@@DadItYourselfDIY Hello I really like this video. Very well done and informative. I am going to replace the valve on my furnace. I was wondering since it seems to have been a while, when were you going to post the follow up video. I would be most interested in seeing it and learning more.

[@chris-bm7jh]

Another thing to consider is whether you’ll even be saving any money attempting this DIY yourself. Gas valve testing and replacement requires specialty tools, equipment and material that can really add up. And some of the tools and material you may not use again, unless of course you have to replace another valve. Learning how to use these tools and materials and testing and replacing the valve itself is also a time-consuming process. A furnace gas valve making noise will require different tools and techniques than a gas valve with an electrical issue. By the time it’s all said and done, a job that would most likely take you a day or two can be done safely and professionally by an HVAC professional in much less time.

[@DadItYourselfDIY]

Great advice. I got lucky for sure.

[@Shenmue06]

A gas manometer is $50, a couple of pipe wrenches is $30, pipe dope and tape is probably $20 and the gas valve is probably around $80-$200 dollars. That's only around $200-$250 dollars which is much better than $800 dollars!!! There's plenty of videos online that teaches you how to do it. I would much rather spend a hour of time and spend $200 than to pay someone $800. I'm a pipefitter though so messing with threaded pipe and gas lines is something that I do for a living. A HVAC technician already owns those tools so charging $800 to replace this valve is ridiculous. I definitely would have replaced it on my own. I think that at least 1/3-1/2 of the population is smart enough to turn off the electric, gas and watch a couple of videos to install it themselves. Half of the population on the planet probably doesn't have enough common sense to shut off the gas/electricity or to properly tighten the pipes so I understand why some people are better off calling HVAC technicians. I understand that HVAC technicians are hard working people that are trying to make a living but $800 for this valve replacement is ridiculous. Just my opinion.

Hello handsome much time without see your videos

[@Shenmue06]

There's no way that I would pay someone $800 dollars to do this job. HVAC technicians are like car mechanics. They 100% overcharge for their work. My gas furnace ignitor knob recently broke because it's made out of cheap plastic. If I would have called a HVAC technician to fix it they most likely would have attempted to replace the entire valve instead of installing a new knob. I was reading online that they have to replace the entire valve because of regulations which im sure would have costed $500-$800. I purchased 2 replacement knobs for $10 dollars online. An aftermarket company makes replacements. I didn't see any replacement knobs from the manufacturer that makes the valve which im sure they do on purpose for profit and regulations. They want you to spend a bunch of money not replace a $10 dollar plastic knob. The aftermarket knob looks and works identical to the oem knob. The aftermarket knob manufacturer made a smart business decision to make those knobs because it probably only costs them a couple dollars to make them and it's something that people need. Personally if I was you I would have purchased and used some pipe dope. It's super cheap so there isn't a good reason not to use it. I also recommend spraying the lines better with water that has a good amount of dawn dishwashing liquid in it. I'm a pipefitter so I can honestly tell you that it's common for people to get leaks so you definitely want to use thread Seal Tape, pipe dope and spray it down really good with dawn dishwashing liquid/water. You honestly made a smart decision doing it yourself. Most issues with central air units and furnaces are things that you can fix on your own as long as you do some research with online videos. I've fixed multiple of these issues on my own. Back in the 90's you would have had to call a HVAC technician but now there's information and replacement parts online. I even replaced my furnace fan on my own. A HVAC technician would have probably expected me to buy an overpriced fan of their choosing and charged me hundreds to install it. If someone is considering doing this stuff on their own they need to make sure that the electric and gas are completely shut off. If you shut the electric and gas line off, find good deals online for replacement parts and watch videos it's totally worth doing it on your own. I found an used replacement fan online that looked nearly new and it saved me a ton of money. Charging $800 dollars to fix your gas valve is beyond ridiculous! $800 dollars for a hour long job is crazy! They probably purchase the parts for a cheaper price than normal, they would have drove 15min to get to your house, spent 30min to install it and another 15min to drive back to their shop so they definitely don't deserve $500-$800. I could understand if it was $300 because the valve might be $100 dollars and then $150-$200 dollars for a hour of their time but definitely not $800! What HVAC technician companies don't understand is that they lose money for charging so much because a lot of people decide to do it on their own to save money. If they would have charged you $300-$400 you probably would have decided to have them install it and they would have still made a good profit for their time.. I'm guessing a gas valve would be $50-$200 dollars so charging more than $400 dollars for the job is ridiculous. That's my personal opinion.
