HVAC Help / Re: Dryer Vent to AC unit clea...
Last post by Admin - June 23, 2026, 03:57:12 PMYou could check to see if your municipality has any bylaws, but most do not and there isn't any building code requirement to place the AC a minimum distance from a dryer vent.
If it's a rental air conditioner and the dryer vent causes parts to fail prematurely, it will be the rental company's problem.
I would recommend hosing off the outdoor coil as it is your electric bill that will increase if the outdoor coil becomes plugged.
You could also install a secondary lint trap on the dryer vent to reduce the amount of lint blowing outside.
Post a picture of the wall where the dryer vent is located. There may be other code infractions that will force them to take action.
If you can, post a picture of the air conditioner installation outside as well.

HVAC Help / Dryer Vent to AC unit clearanc...
Last post by lturner19 - June 23, 2026, 03:06:07 PMHi all,
We just moved into a house in Ontario and noticed the AC unit is only about 6" away from the dryer vent outside. We can see the lint piling up in it and are hesitant to even turn it on. It is a rental and the company says it was installed in the house in 2019. A quick google search "highly recommends" the AC unit be 3+ ft from the dryer vent (I know I know, "google says").
Is there any law/regulation/requirement that confirms this??
The rental company says it's fine and "it was installed in 2019, so we're sure it's fine" and want to charge us 2500+ to move it away from the vent.
Have also reached out to manufacturer (Carrier) to see what their requirements are for installation but have yet to hear back.
Thank you

General / Unsafe, Uncertified Installati...

QuoteToronto, ON, June 18, 2026 -- Robert William Seager has been found guilty in the Ontario Court of Justice for working without a certificate on more than 300 gas appliances in the Durham Region.
The Court sentenced Seager to 30 days in jail, along with a $10,000 fine and a mandatory 25 per cent victim fine surcharge, bringing the total financial penalty to $12,500. He was also placed on probation for two years.
Seager was convicted of one count of doing gas work without being certified, in violation of section 6(1) of Ontario Regulation 212/01.
An investigation by the Technical Standards and Safety Authority (TSSA) found Seager carried out gas work without holding the required TSSA gas technician certificate and operated as an unregistered fuel heating contractor. He accepted payment for installations that were incomplete and deficient, requiring corrective work by others.
Investigators also found he improperly installed a water heater that contributed to property damage, and he worked on more than 300 gas appliances without certification across Durham Region.
"Unlicensed gas work poses a serious risk to public safety," said Owen Kennedy, Director of the Fuel Safety at TSSA. "Certified technicians are required to meet strict safety standards. When they operate without proper safety credentials, they put people and property at risk. TSSA will continue to take enforcement action to protect Ontarians."
In 2022, Seager was convicted and fined $4,000, plus the victim fine surcharge, for the same violation.
Residents who are concerned about work that may have been done by Robert Seager are encouraged to find a local TSSA-registered contractor to do a full inspection.
In Ontario, only fuel contractors registered with TSSA and individuals holding a valid gas technician certificate are legally permitted to work on fuel fired appliances. Before commissioning any fuel work, members of the public are encouraged to search for and verify registered contractors using TSSA's online Authorized Heating Fuel Contractors Lookup Tool.

HVAC Help / Re: Static Pressure test
Last post by Brian270 - June 06, 2026, 09:22:04 AMQuote from: Porcupinepuffer on June 06, 2026, 08:42:07 AMI would have liked to see the return air to the furnace done differently. I would have used two large radius elbows back to back between the filter rack and return air plenum. That would cut down static pressure on the return side.Thanks for your comments.
I also would have made a proper starting collar and transition from the supply plenum for the two supply trunks leaving the pair of pants. It shouldn't feed two trunks from a smaller opening if those two supply trunks were sized for what's needed. I do see the damper mostly closed for the smaller trunk, so maybe all that flow isn't needed.
I also would have liked to see some radius elbows used. Will know more once we do a heat rise and likely static pressure tests.
Yes, the damper is closed a bit to try and force a bit more to the upper floor. We are experimenting still but really need to know if the static pressures will allow us to pinch these back.
My installer is a great guy and did a really good job of helping with this rather large undertaking with minimal intrusion. It was a balancing act of getting enough heating/cooling to extreme parts of the house without ripping into walls and ceilings too much. We are hoping its going to work out.
So far it seems to work ok, in heat mode the upper bedrooms are a bit cooler than lower levels (hence damping the one trunk)and the whole system is rather loud but we aren't used to forced air so may take some getting used to yet. Cheers

If you are going to use the high MERV filters, then just change them regularly. Did they record the startup numbers in your manual?Thanks Hgye,
Start up numbers? What numbers should they have recorded?? I haven't seen anything.
