Great content. Please post more!😊

Should have checked before fixing it

Checking for carbon monoxide is the first thing you should of done. I wouldn’t be wasting your time on maintenance. Especially on a 20+year unit. Condemn it and move onto the next one.

Why were you getting a reading from a natural draft furnace and water heater.

Great job. Like MikeyPipes says "hacks bring me stacks". Will you start making videos again?

I think you could have visually looked at that flue pipe and noticed that there was a problem Houston

Have tenant tap on lineset at a/h with a wrench ... go around to each unit on roof and listen.... sound really travels...

Could have not powered the reversing valve from downstairs with 24 on and off and had the guy listen for the valves clicking on and off ?

Dude you need to get your self some electric tools to get those screws out. Or if you do use them

Great Video.

Great job! Once I found out it was an old furnace with a pilot light, I would have stopped there, disabled the furnace, and just made sure the ac was working. Reason being, had it not been for the cracked flue pipe with the leak, the customer would have continued using it until it messed up again. In addition, those old furnaces are just a waste of time to clean and fix! At any rate, that was a thorough job. Post the installation if you can. Thx

Prefab C-boxes from the supply houses transition better than a collar to a box like you did. That being said, great job but tapered is better. I also like to duct mastic everything instead of silicone. Just put your metal together and paint away. Different strokes for different folks. No criticism here, just trying to help.

so no combustion analysis or visual heat exchanger inspection, to determine if the heat exchanger has a failure? so you found 5 feet of old flue pipe that needed to be changed and your hoping to get a change out. stop posting this type of video unless your trying to find your self in court. yes the furnace is old, yes single wall flue pipe leaks when it is new. those PPM well check OSHA standard. you found no CO in the air flow in the office area. word of advice from a very long time licensed pro take your red sticker and stick it in your brown hole hack. you would be fired for ethics reasons at my shop.

On the white wire

If his electric heat strips are on then he would have 24 volts going out from the unit to the air handler

Red to y would show 24 volts you have to go from common to y

Or you could wire nut the thermostat wire together and olm the wires out

This is why hvac guys should carry a toner I know it would still be a lot of work but you could find the right unit for sure

Nice job dude. Only so much you can do with it. It’s not your fault she has to pay twice. She has learned a Valuable lesson and you gained a customer for life.

An auto garage with 13ppm. Better call 60 Minutes.

First thing.. grate job.! You will get more business wen people know what kind of work you do. And how you do what's right for your customers.. trust me on that ..

Weird! The rest of the installation looked legitimate. It’s bad enough it’s a central return. But a piece of flex instead of a plenum? Crazy!

I curious if when they were installing it they could have just moved the whole unit out a few inches & redid the gas line and the vent pipe instead of smashing the duct up. Or used a multi takeoff on the return plenum and use two smaller pieces of flex to make up the right size for the return air?

I own an HVAC company and I would have her take the company at fault to small claims court. That install is an abomination and I would have them reimburse her for your time and repairing the system to working or to manufacturer specification.

Furnace is old so definitely needs to be replaced. But what’s the reason your going to be replacing it ? Is it because you found 15 PPM CO2 on the flu pipe ? As far as I know on a flue pipe you always find less than 100 PPM and it’s normal, even tho the limit is 400 PPM..

Very nice work ! Under-sized returns. See 'em all the time.

Wow! There is a God

Doesn't look bad but I hate when people don't put filter back grills in so now the whole duct line gets dirty I guess you do it this way so you can go back in a few years and charge them again to clean the return instead of spending a few more dollars and putting in a filter back grill in that would prevent having to clean the return in a later date

Noway to ring wires out

Use some lights

I c that here in my area return way 2 small helpers learn basic installs but not proper sizing 12 x 12 wow.

Great work! What should something like this cost?

Props for doing the right thing. You're absolutely right, honesty is the best policy and best business practice, always. Curious about that voltage reading on the new thermocouple. 242 VDC? I'm thinking it's probably 24.2 mV DC (millivolts).

So the duct work just needed to be replaced? Or should no unit be producing C02?

You should come in the house with your CO detector on. If its running or soon as you restore heat it will be detected. Check HE before you waste your time..

Nicely done. Gotta take care of the customer

Wow good thing you checked...

You mention customer didn’t want to pay for weekend service call. What’s the typical charge for weekend call during heat season?
