I use an attachment to the drill that cuts metal. About 8 to 10 bucks when I bought it. Two, I use rivets. Simply drill a small hole, add the rivet then pop it. I would round the holes where that filter goes in too. Those rivets make it a lot more sturdy and are very inexpensive. The rivter was about 15 bucks.
@@TaddyDigest Yo whats up brotha. If the furnace is installed in unconditioned space wont the new return now screw with the the systems ability to heat and cool the rooms upstairs the way they were designed to?
What should you do in case of a gas water heater next to the furnace? Can you split the existing return ductwork and tie it to the other side of the furnace? Will it increase airflow?
I also have a hot water heater next to my furnace, like in one of the questions before. Can I split the existing duct return and tie it to the other side of the furnace. Will this work? Will air flow increase?
16 INCH ROUND IS GOOD FOR 1400 CFM, I HAVE THE SAME SENERIO. I REALIZE MORE RETURN IS BETTER BUT, DO YOU COUNT THE SQUARE INCH OF THE RETURN VENTS OF THE DUCT SIZE OR BOTH. EXAMPLE, ALL MY RETURN VENT ARE CLEARLY MORE THAN REQUIRED FOR 1400, BUT, MY RETURN DUCT JUST BEFORE MY 14OO CFM RETURN PLENUM IS A LITTLE
Is it ok to install a return in a garage? Isn’t there a chance for it to pull in carbon monoxide? Or is that considered a basement with a walkout garage looking door? Thank you Tad
As a licensed general contractor, I totally object to this practice, and any competent building inspector flag this as an egregious code violation. A garage is NOT a good place for a cold air return. It will positive pressurize the house at a large energy penalty unless there is a jumper duct from the house to the garage or there is an appropriate amount of supply ductwork conditioning the space in the garage, which in this case would be far too much for the space. Either way, they are creating unhealthy indoor air. For fire separation and safety, GARAGES SHOULD BE TOTALLY SEPARATED AIRSPACES FROM HOUSES, ESPECIALLY IF THEY HAVE CARS PARKED IN THEM. Read up on the ICC rules for garage construction if you doubt this. Far too often, HVAC work is about fixing something horrible by doing something bad. I am a general contractor tired of the abysmal standards of HVAC industry. Just because the air handler blows harder with this quick fix does NOT make the overall system more efficient, and it is unhealthy to mix garage and indoor air. Sometimes, partial knowledge is worse than complete ignorance.
I agree that's why in this video I explain that this is not being used as a garage anymore. Homeowner was remodeling and removing garage door and closing it in to make it a conditioned room. Thank You for sharing this knowledge
why say "No pun intended" when you still used the word cool. You acknowledged it in writing which means you could have said something different. Why even acknowledge No pun unless you actually meant the pun?
@@briannatarelli430 Im going to tell you why. Its because, it doesn't matter to me that it would have made a pun. I think puns aren't funny generally, and i dont want it to be a pun just because I used a common word like "cool" and we are both hvac technicians. It would be very low brow if I was like "cool!, pun intended! Hehe!" but maybe thats what you expect from a tradesman so you ask? What do you think Im a school girl or something?
imo this was a bad idea...ur taking to much return air from that basement area and not the living area...u should have tied the return into the living space some how..u can never have to much return but u want it from the space ur conditioning
@@TaddyDigest I know this would help supply and supply is my issue some but mostly return is my issue. Can I use this method to connect it to a drop down coming from the existing duct run?
Hey Teddy. No offense, but I cant believe my eyes that you posted it 😂. 1) Fire the guy, who put the screw towards the filter rack. He couldnt put the filter himself, how could the customer slide it in? 😉 2) Is it allowed in your state to put the return in the garage? (Risk of sucking car exhaust gases) 3) wont there be a negative pressure in the garage and positive pressure in the house?
That would never pass any code or inspection, especially when they go to sell the house. Hot ass air from the garage being used for return air regardless, if there park in there. That is what a hack does and an inspector would have a heart attack. I told you I would be around more. This is the kind of crap I expect from a hack of a DIYer. I hope nobody ever follows your advice or they will be in some trouble some day. Garages have far more than just exhaust fumes. All returns must come from inside the conditioned space when the air handler is installed in a garage or building that isn't livable space. There is no way you are EPA 608 or NATE certified. I bet you don't even have business liability insurance. Garbage work and can't even follow simple code and rules.
I'm glad you're around Keep reading those books buddy Sometimes you gotta do what you gotta do for the unit to work and for the customer to have heat and air. But I guess you wouldn't know am I right to assume? Let me know thanks for watching
Just to let you know is Actually 500 CFM’s times two for that 20 x 25 because theres 2 CFM for every one square inch of filter space…so you really only need 200 hundred more cfm
Great idea in theory but your not supposed to put a return in garages because of automobile combustion gases could enter house which means s a extremely dangerous hazard. Where I am the would be a code violation but more importantly the potential hazard is more of a concern.
@@TaddyDigest I’ve watched enough of your video to know you do things correctly and to a high standard so I was pretty sure you weren’t doing anything unsafe but not all that watch know these things and it could be an issue if someone does that without being well informed.
That filter fits like crap. Next time put the actual filter up to the furnace and trace the corners with a pencil instead of trying to transfer measurements with a tape. You can size your hole accurately and get the angles on better for a good fit. This technique of measuring works in a lot of situations BTW instead of transfering measurements.
i remember those days, and sometimes i miss them days... great cutting !
fresh out of school and still have a lot of questions, but slowly everything is clicking into place, Thank you Tad!
same here
I have a problem in heating mode where the flame is rolling out due to no having enough airflow
I use an attachment to the drill that cuts metal. About 8 to 10 bucks when I bought it. Two, I use rivets. Simply drill a small hole, add the rivet then pop it.

Is this Chattanooga?! That’s where I’m from and I’m in my first year of HVAC love your videos, they help a lot!
I'm in tennessee about four hours of Chattanooga

low air flow will cause a low side pressure. true coil will freeze line set will also freeze.sum times airflow is number 1 problem.
So we can cut an opening on the side of the furnace for the return?
yes
Where can I purchase the angles used for the air filter rack installation?
distributor/supply house or online
my furnace doesn't have a return, just open air then filter. do I need a return?
Having a return centrally located in the house will give you better comfort and efficiency for the equipment.

If my furnace has a 5 inch, Merv 11 filter, do I need to add air filter on 20"x24x1" return vent?
not sure
I do not know what size your ductwork or your unit is
@@TaddyDigest they are about 18-20 inch in diameter
What about safety concerning vehicle gas exhaust?
@@doeleen this is not a garage anymore it’s going to be a add on room
Who did the R/A on the left side😂😂. That looks goofy and looks like a DIY job😂😂
Wouldn't this cause suction pressure and head pressure to rise since your adding all that heat from the garage into the system?
Well, they are insulating the garage and turning it into a room, so it's going to be conditioned
Is it ok to install a return in a garage? Isn’t there a chance for it to pull in carbon monoxide? Or is that considered a basement with a walkout garage looking door? Thank you Tad
it's never ok to install a return in a garage
unless the house it being remodeled and the garage will be a room instead
Can you explain or point to a video about a Static Pressure Test.
I have one I just haven't posted it yet.I will post it soon
Can the system ice up with too much return? I've seen two returns on a 2.5 ton 16 and 14 flex on it.
Not enough return will cause it to freeze up
For a 3.5 ton unit shouldn't you have the unit operating at 400 cfm per ton on the furnace control board?
Yes that would be ideal
Use a muti tool with carbon blade works good keep the blade at an angle.
Why not just remove the 16” round and put a 20x25 duct in between the return drop and the filter rack? Seems like an unnecessary step.

undersized return can affect refrigerant pressure. Another thing I learned. Really cool. No pun intended..

Not sure I understand if 40 to 50 is a lot and you need to get to 70 you're still way off and you didn't solve the problem
