I had a furnace fail once and called a HVAC company. They charged me $250 to come out and diagnose that it was the flame sensor and clean it. It's a good idea to know what to do and it's a good idea to clean it every year.
Amen to that, thanks for the feedback David.
I have one better. They serviced the furnace then routed the a/c drain line higher than the catch basin. Destroyed my furnace because I didn't notice it for months. The exchanger was rusted badly.
Before you call an HVAC co, ask for references from a friend or neighbor or a trade association. Most cos. are honest and some not!
For $250 they should have at least replaced the sensor as it's a $15 part..............
HVAC companies hire morons that couldn’t make it as plumbers
It is amazing how much dust collects inside of a unit. “A Good old fashion cleaning” was a great way to explain that part of the video. Great video Scott and Dave!
Thanks Josh 👊
Thanks bro! We appreciate the support! Cheers

@@EverydayHomeRepairs You got it!
It's smart to do the annual furnace cleaning DIY. Last time I had a tech do it, he slapped "condemned" stickers on my perfectly functional furnaces due to "cracked heat exchangers." Showed me grainy pictures with hairline fractures on them.
I got a second opinion. They told me the first outfit was notorious for the "cracked heat exchanger scam." That was 5 years ago. 18yo furnaces still running great.
MY Goodman Furnace was working properly, all components seem to be working properly, but the furnace won't keep the running after it ignites, looks like it's going to start then shuts down. The problem was this furnace is 4 years old and the black feed pipe that the burners attach to have brass fitting for each burner with holes where the gas comes out. Those holes were partial covered with carbon. I took the black pipe off, removed the brass fitting and pushed a tip cleaner through the hole in each one, put it back together Bingo furnace works fine. I also took the Flame sensor out and used fine sandpaper to clean it. So simple to do.
@@briananderson6142 most likely was the flame sensor
@@gtarules1 It was both the Flame sensor and the gas feed from the pipe that feeds the burner end. It was partially blocked with carbon that slowed the gas flow. You can't buy an extra flame sensor in Canada without a gas ticket.
Great video Scott. I followed your instructions and brought back to life my old furnace. much appreciated
This is by far the most CLEAR and concise instructional video I have found, and also explains everything in detail. I hope there are two others just like this one that go into more detail about cleaning the blower wheel and evaporator coils! Thanks!
That was nicely explained. I haven’t seen any such a easy process for maintenance. I never checked my furnace for 15 years. This year just before the winter I decided to call a professional for checking. He came opened cover cleaned the sensor, removed little dust with brush and VOILA. He didn’t even check the filter.
$150 +HST. In less than 10 min.
Now next service in 10 years, and by my self.
Thanks for video.
@Sammy He charged you $150 and he didn't check the filter? Well, at least you know who not to call for service the next time you need it!
You probably don't want to wait 10 years before doing the next maintenance on your furnace. Once a year is the recommended interval.
Right at 3:30, the words Sensor and Ignitor are actually printed on the panel. That helps as well. 😊
Solid video. My furnace was acting up earlier this year. I know a guy who has been in the HVAC business for years. These were some of the steps he talked me through over video chat.
Nice, thanks for the feedback!
Yes sir, you are spot on! Regular preventive and servicing of literally every piece of equipment in a standard home requires due diligence.
Great tips on the flame sensor! I have a wood working shop by the furnace and have to clean it regularly!
Thank you bro you save me lots of money it’s refreshing to see a video that’s so well explained thank you
Happy to help!
Thanks for this video. Easily just saved me a couple hundred dollars by showing the issue with the flame sensor. Instant success!
Thanks for the tips. Easy to follow, and very timely this time of year.
Great instruction and information. I converted from oil to a gas furnace 3 years ago and the HVAC installer recommended the first furnace cleaning to take place now that the furnace is 3 years old in order to maintain the warranty. Wow! what a difference from an oil furnace. My father was an oil burner mechanic until the late 50's, but he continued to do furnace cleaning for friends and others as a side hustle for many years and I helped him as a kid. We would vacuum pounds of black soot out of the furnace, the flu and the base of the chimney. Several measurements were taken and several adjustments were made to calibrate flue draft, burn temperature, pump pressure, cleaning and setting electrode gap, spray nozzle replacement, check and tension the fan motor belt and oil the shaft bearings, electronic photo flame sensor cleaning or replacement plus a host more. Finally you'd change the filter(s), re-prime the fuel pump and you'd be ready for another heating season. I'll continue to have the HVAC specialist in every 3 years until the warranty expires, but now I'll do my own annual maintenance in between and after the warranty. WHAT A DIFFERENCE?.....and simple procedure!
Wow! I have a fuel oil furnace and until last year have had it serviced every fall. I can tell you that of the 3-4 companies I used over the years, no one did all the things your father did! How do you find a conscientious and responsible person/company to do everything necessary when you’re a single 71 year old lady? 😳
@@BobbieJeanM you want to find an hvac shop with good reviews from a service like Angie's List. These companies work hard to keep good reviews on that site, im telling ya....
This is a good general check for a DIYer, and it's something I do every other year. The times I don't do it myself I pay a local company to do a little more detailed tuneup that includes inspecting the heat exchanger for structural issues like corrosion, current draw tests to check the operation of the electrical components, and actually removing and cleaning the burners. It's a system that's worked well for me for a lot of years. As for the filter change interval, I use a pleated filter with a midrange MERV and change it every other month. I run my HVAC system fan constantly, so I felt 2 months would be better than the filter company's 3 month claimed life. You don't want to allow a filter to become too restricted; the real reason furnaces have filters has to do with protecting the internal components, not the air quality in your rooms. Using very high MERV filters restricts the air flow and causes your blower motor to work harder than normal. The same can happen with lower MERV filters if you leave them in too long.
Thanks for sharing this knowledge with everyone! Most of the time homeowners just assum hvac guys are doing a good inspection when in reality they’re probably browsing the web on their phone for an hour down there 😂 It’s just nice to be educated with your hvac system which you clearly are! Cheers friend
I bought the cheapest furnace I could find 25 years ago, a Goodman, installed it myself, and it's just been chugging along for 25 years now heating a 100 year old home in Montana winters. Never been inspected or cleaned. I did have to put a new ignitor in it once, and we change the filter every 3-6 months but other wise it's set it and forget it. I will definitely buy another Goodman if this one ever dies but it was under $1000 25 years ago and it owes me nothing at this point. Had I been spending even $100 on inspections the last 25 years I'd have already wasted more money than a new one will cost.
@@bryanhersman4037 wow, you'd be lucky to pay $2000 for one now! Let me know if you do 😆
Thanks for the info! I'm on it, confidently!
I don't why I watched this video--I don't have a furnace. Good information to keep in the back of my head.
Good, clear explanation. Thank you, this info will be useful to me.
Great vid, would love to see the same / similar maintenance for electric heat - baseboard homes.
Good basic video, just had my heater go out as its getting cold here in Chicago and remembered I didn't do any maintenance this year, didnt panic, followed this video and cleaned everything off changed the filter and BAM back up to 70 degrees in no time. THANKS!
I think we all should be cleaning the flame sensor after every heating season.
Excellent. information given was very clear and concise.. Thank you
Great presentation, well appreciated!!!
Greatly appreciate this video and all the tips plus the safety part of it to.
Glad it was helpful!
Very good and clear description. Nice that it was the same furnace I have.
Yeah those Goodman furnaces are Super
Common 👍
Great video!!! I want you thank you both very much for your detailed expertise in your fields. I am a newer followers but already have used your videos to help me get through a lot of DIY projects that have saved me a lot of money. My son and I will be working on our furnace tomorrow to get ready for the weather change. Thank you again!!
As an hvac technician this scares the crap out of me. What's your gas control pressure set at? Properly sized vents? What was CO/O2 from combustion analysis? Ambient CO?
😂😂😂😂
@@robertotorres284 CO poisoning incoming
@357 Don't be mad because people don't want to hire you. Did you go on the HVAC technicians page and say stop giving away our secrets your killing me over probably not. So you decide you're going to come comment on my thank you to him like I won't say anything and just let you talk shit. This is what happened when Covid hit and technicians were too afraid to go to people's houses. They had to fix stuff on their own and smart technicians saw a way of making money using social media by helping them through social media and are now probably making more money than they did before Covid. So just type away keyboard warrior and continue not making any money!
@@robertotorres284 i make over 6 figures and can easily prove it if you want 😉 you're a dumby handyman who may kill his whole family cause you're cheap and can't hire professionals. Oof
Awesome. I knew how a furnace worked but I still learned something here. Thanks.
Thanks for watching! Cheers man
Coleman made good furnaces too! lol
Outstanding. Great work yall. Thanks pleyas !!!
Excellent informational video.
Very timely. Thanks, Scott.
You bet!
Great information. Thank you
Bro ty for your videos. Helped me out a lot!
I think I have had that problem twice over the decades with the flame igniter. Thanks.
Very valuable information. Thank you for sharing
Thanks Hassan 👊
Thanks for sharing this.
CT - clng $195, sometimes more.
Thank you so much for this video.
Dang! Thanks for the feedback.
Thanks Great video - FYI-- Blow out air lines on air pressure sensing (vacuum) switches - Some of these air switches has two contact - one on the front one on the back .... check both!
yellow powers both switches - brown and orange are the two different outputs signals. Inducer housing pressure and collector box pressure (check square tubing vacuumed sensing signal). This may apply to your unit.
nice job, thanks
First time having a furnace, and I did not know this sensor needed maintenance. I bought a mini screwdriver ratchet bit set from Harbor Freight! A small multi stubby screwdriver would work also for tight spaces. Thank you for your video help it's much appreciated!
As a homeowner, you should always have a spare hot surface ignitor and flame sensor by the furnace too.
Thank you, I will keep spares.
Great, my furnace was shutting off, I cleaned the flame sensor. You saved 100 bucks and I feel warm now. Thank you
Happy to help!
Probably closer to $200 or if after hours on a weekend, closer to $400 or 500 bucks
Excellent video!
Thanks!
very good video great information
Definitely change your thermostat batteries every year when you do your smoke detectors. My batteries leaked almost damaging the thermostat. Had to clean the battery connective and a bit of stuff on the circuit board before the new batteries worked.
This was so useful. Thank you so much.
You bet!
Really helpful stuff! Definitely made the inside of my furnace less intimidating
watching this before the winter storm coming
Very good info
I just cleaned the 'flame sensor' on my 4 year old Daikin Furnace, it was cycling on and off every 2-3 minutes, not super cold outside so that kept it kinda warm and had time to view your videa. Probably a million with similar info on here but I watched yours and Problem Solved ! Thanks ! ! !
Awesome sauce. Glad you saved some money and were able to do it quickly. The best part of all is that when it does it again, and it will, you will know exactly how to fix it! Cheers
Id keep a spare next to the furnace at all times. Replace both the hot surface ignitor + flame sensor at about the 10 year mark.
GREAT!
Also oil the draft motor shaft to bushing points yearly with a few drops of car motor oil in a bottle with a long neck or use zoom oil.
Also use your long narrow flexible refrigerator coils cleaning brush and clean the blower cage fins once every 5-10 years.
Take care
Thank you
Nice my man. Be proud
I took my rod out but it was L shaped on the end. Had a terrible time getting it out. I noticed the bend and was able to get it out once I realized. It was corroded so it was good to clean it. Thanks for the video. Everything is so expensive these days. It’s nice to prevent things from falling.
Right if and if you call an HVAC company they might come out and tell you you need new furnace.
@@crand20033 This Is what they seem to do. I took my car into Honda for repairs recently and they told me I needed all new rotors, brake pads were down to 1 mm, callipers need to be replaced. Cost? $2,890. I took my car to an independent repair shop and the guy showed me the brake pads. 5 mm left on all of them. I saw it with my own eyes. Nothing wrong with any part of the brakes. Callipers working fine. They lied. I avoided a huge bill.
@@ds99 Dealers are the biggest rip-offs.
@@crand20033 They lie like thieves. As much as I like Honda vehicles, I don’t know if I’ll buy another one.
@@ds99 They overcharge for sure.
Nice tips, thanks for that
You bet!
Thank you sir. Do you have a video for fuel furnace maintenance?
Thanks
Interesting that he touched on the Combination smoke detector. that's what brought me to this video. to maintenance my furnace as per my FD recommendation after a visit to my home because of the Combo detector falsely went off.
Thank you so much for posting this! I'd had three different companies come by to look at my furnace, they dinked around with it for about three hours each and said they had no idea what was wrong with it, but charged me through the roof for looking at the furnace. (Not a lot of great service out here.)
Wow, I’m sorry to hear that. Did someone eventually get it figured out?
@@diyhvacguy Yep, eventually, the fourth guy said, "Oh, you don't do your own yearly maintenance and cleaning? That's weird, nobody would think to check that." Turned out I'd been using a cat litter that made a little too much dust in the basement, and soot had built up. Changed to a different brand, and now I know how to clean my furnace, thanks!
@@kerikrogel9126 wow! That’s really weird. Glad they got it figured out 👍🏽 cheers
Both furnaces shown in this video have the same code violation: the gas supply line should have a sediment trap AKA drip leg before going into the furnace (although in some cases this is installed within the furnace, before the gas supply feeds any furnace components).
@@stevebabiak6997 theres probably about .05% homeowners that would install that into the gas line if it wasnt there. Just sayin....
Thanks.
Great video
Pretty good tips and I do that myself usually every other year except filter replacements obviously. Why every other year you might wonder? Because I simply forget to do it on a yearly basis with everything that is going on. I also keep a manual near by for a quick reference and I have purchased a few spare parts to keep near the furnace like hot surface igniter and a flame sensor thingy which are not that expensive but will save your bacon on a -35 January day. Might get a pressure sensor too, as this is a failure point on some furnaces from what I understand. Motor lubrication is not required according to my manual but I still wonder that one point myself.
I would love to see a video like this about oil furnaces. I'm sure there are some differences.
YOU DID PERFECT JOB 👍👍👍👍👍👍👍👍👍👊👊👊👊👊👊BASICS NICE SIMPLE TO THEPOINTS👍👍👍👍👍
Thank you like your video, quick question I have a smart Honeywell thermostat and recently when I started running the heater the thermostat will shut off and restart several times but the heater stays running any help would be great if possible thank you
1 quick question on the flame sensor. Removing the flame sensor is easy put upon reinstallation do you want to censor to be right in the middle of the burner or to the side? It seems ours is alittle off center of the burner. A pic would be good if possible. Love the channel and your very clear with everything👍
I use an air compressor to clean the filter outside..works like a charm
i tell all my customers to pick a holiday. that day is thermostat battery day.
Any chance you can demonstrate this on a gas boiler as well? Thanks for all the content.
One thing that is helping me pay attention to this video is that I have the exact make and model of this furnace. Now I have no excuses!😝
I took a label maker and printed out my furnace make and model number on the outside. Alot easier when on the phone getting parts.
@@srobeck77 Great idea.
Good information. Disappointed that you didn’t cover cleaning burners.
Checking the mfd of that capacitor while you’re in there cleaning the blower section.
Nice to see you adjust gas pressures and do a combustion analysis
Let me know when one of your videos get a homeowner killed?
Money saver!...👏👏👏👏
My furnace has a screen inside the air intake pipe that needs to be cleaned. It is where the pvc intake pipe connects to the intake of the furnace, this was a course screen to trap bugs, bats etc, original Bryant part. Scotch Brite or steel wool on flame sensor, clean out moisture condensation trap.
I always date the furnace filter when replacing.
Great video especially for me because I have a 20 year old Amana furnace that looks identical to the one in the video.....I clean both the flame sensor & the igniter with 600 grit sand paper every fall.....The only major problem I have had with my furnace was after about 10 years it started to leak water from somewhere from inside the top portion.....Called the installer to look at it and he did absolutely nothing to fix it so after winter was over I took it apart and found out the plastic recope cover(The thing the inducer motor is attached to) was cracked at 3 out of the 4 corners.....Replaced it and she has been running great for going on 20 years now.
Id recommend installing a new flame sensor and hot surface every 10 years at the latest. So at 20 years, I wouldnt bother cleaning them anymore, just replace them.
@@srobeck77 Yeah I'm on my 2nd set of ignitor/flame sensors in those 20 years.
@@Riley_1955 mine started sending infrequent ignition error codes at the 4 year mark and then was locked out just this year after only 6 years until I replaced them both. I always keep a spare next to the furnace. Thats pretty early to be failing, maybe it was a defect.
Cant wait to see how long the new HSI lasts for. I was showing the new one compared to the old one to the wife and she friggin grabs the new one (never supposed to touch them). I go why the F would you touch it, goddamn it....
@@srobeck77 Nothing wrong with either one I just replaced them both about every 7 years just to keep on top of things and all previous ones were kept as spares.
Good points, the draft inducer motor on mine failed a few years ago, changed it out, then noticed it has bushings instead of bearings and needs a little oil once a season.
This is a new style pilotless gas furnace. The older style has a flame sensor that's a thermocouple for the pilot light (which doubles as the the igniter), has no hot surface igniter, or draft inducer motor. Inspecting the burners for corrosion and periodically cleaning them is necessary as the old furnaces have cast iron burners with thin flame openings that can develop rust during the "off" season, (especially if the furnace is in a basement). Some older units have bimetal limit switch assemblies with mechanical contact switches whose contacts can become pitted and require polishing or replacement.
By "new" you mean the standard for the past 30 years now on furnaces? Hot surface ignitors have been around a long time now LOL
Most sleazy service guys try to sell you a new flame sensor instead of just cleaning it. Thanks for being honest and showing how to maintain it.
Yea, its ridiculous how much hvac guys are taking advantage of people. They find any way they can!
How do you know that most would sell you a new flame sensor? I work in the industry and that has not been my experience. It's way more common to clean the sensor and rarely are they replaced. So, curious where your getting your information?
@@furnaceworlddispatchemail4831 Lol right. Aren't these handymen on here hilarious? Dudes furnace is prob 30 years old with a hole in the primary. These CO induced comments
@@furnaceworlddispatchemail4831 i know a few service guys through companies ive worked for that definitely sell the homeowner new parts when the old ones work fine, flame sensors and thermocouples are among the most common. It definitely happens unfortunitely, you will see this in alot of service work. Theres alot of shitty people out there
All these know it diyers eventually need to call a professional and then piss and moan about having to pay a premium for the service and knowledge of an experienced technician. Most homeowners are clueless as to what it takes to own and maintain a service company. When I get a new customer with the “everyone is a crook or so and so tried to rip me off” that’s a huge red flag and I drop them like a bad habit.
You need to put videos out on a package units
Wish you would do one for an oil furnace
Omg, the hacks are multiplying! 😂😂
Hmmmm, great video guys. I had a new furnace placed about three years ago and it has been solid, however this winter it smells very dusty. So I started exploring. I sucked out a lot of dust out of my ducts with my shopvac and just had two long extension to the hose. I have my calendar set to replace the furnace every 10 weeks, which seems ideal. But I never took time to look further into the operation of the furnace. We are always: Let's call someone.... which never happens. But this video encourages me to at least take the cover off the furnace and see if I can identify the parts. I always have the attitude: If I don't know what I am supposed to do... I will read up and even if I am not certain I will call the maintenance guy in our condo and pay him under the table to show me what to do. There are actually very good drawings on the inside of the furnace, I saw that when they put it together in our crawl space.
👍🏻 Thank you.
You bet!
Do you habe a video to turn off gas heater for house? Idk if i should turn off switch or gas line first. There is a separate gas line for house heater
Merv 15 carrier infinity electric air cleaner filter says to change once a year. Is this a good or bad practice?
Being in the HVAC business I can tell you that paying for a yearly furnace check up is a complete waste of money.
I went to the Dollar Store to buy a dollar bill to clean the flame sensor and it cost me $1.25 because of inflation. I'm going to save it for next year incase prices go up again!
I prefer a trap on the evaporator condensate drain separately piped from the tee or standpipe of the furnace condensate drain.
I need this kind of info for an oil fired forced air furnace.
My daughter has terrible allergies that seem to be related to our house. Is there anywhere in the furnace that might be a possibility for mold build up?
You should go over cleaning the condensate trap on these high efficiency units .
Plug the end of the hose and dump 1/3 vinegar mixture and let sit for 10 min. Nuff said : P
He mentioned that he has a video on his channel for how to clean the blower motor but I can't find it. Can you possibly post a link to that? Thank you!
Is there a reason the flame sensor or condensate drain wouldn't be checked or tended with a regular maintenance service?
My furnace had dirty filter which was causing the furnace to turn off due to over heat. After changing the filter still had issue, getting error code. I compared the error code it was a fuse that was triped due to over heat. Reset that now everything works perfectly.
Had a yearly furnace check. The tech did everything but to check the vent, chimney, pipe. It was rusted with many holes. Totally missed it. I replaced it.
It’s better to use a $100.00 bill to clean flame sensor. Thanks Ted .
I had my newer furnace fail twice from something very simple and it had to do with with my humidifier and the condensation pump , there’s this clear plastic tank behind the upper access panel that I believe is part of the humidifier system , it gets gummed up and trips the safety circuit , the other time condensation pump wasn’t pumping out because the GFI tripped and that tripped a circuit in the furnace and it happened at the worst time . My furnace guy said he couldn’t make it to my house for two days and it was cold so he asked me how my mechanical abilities are and I told him and when he was satisfied he gave me a few common things to check and I was able to get it going both times . All these furnace add on’s can be a pain in the neck form a the safety features they have .
Yeah, the need for a condensation pump on the high-efficiency furnaces is a pain especially in rental units. Almost guaranteed to fail at least once in a 3-5 year span.
@@EverydayHomeRepairs , at least it’s something that can be disconnected and manually drained , if I turn the water off for the humidifier . I’m not a furnace repair guy but my furnace guy gave me the common causes ,now after watching your video I took notes and put them on a note pad on my phone for quick reference
Do you do a yearly maintenance for an electric home furnace?
Hand fasteners, aka thumb screws
I've had my furnace for 38yrs not one problem. The only though is you have to disassemble the moter from the squirrel cage just to oil the bearings. I like a pilot light. It keeps humidity from collecting. Never had any long term success with quartz lit anything . All good things must end. I'm going to get me a new one soon. Why? I've pressed my luck enough. Damn I hate to give the Intertherm up.
I would have wanted to see info on how to choose a replacement filter based on MPR / MERV specs. I have read that a too restrictive filter (like perhaps a MPR 2200) can put stress on an HVAC system. Is that true? Very helpful video - and timely!
Yes, it's absolutely true. I recommend the basic pleated filters.
Yes, a overly restrictive filter can definitely have some negative effects. I wouldn’t advise doing a higher merv rating then needed. Anything above merv 12 is considered hospital grade and not really needed for residential applications. I’ll be coming out with a video on this subject soon! Cheers
Not an expert, but yes, I've also read the finer filters stress the system. To mitigate this, you'd want a thicker filter (like the 4" ones instead of the 1".
@@diyhvacguy Agreed, above merv 12 is stressing out your fan motor too much. At that point, just vacuum your house more and shampoo it annually
