I verify the temperature rise, and only if it's out of range will I start checking ductwork and fan speeds.

Sorry but Im kinda floored nobody replied to this question.
My HVAC guy says nobody does TESP tests yet all I read and watch on internet is HVAC pros doing this like a doc taking your blood pressure.
Thoughts? Cheers

HVAC Help / Static Pressure test
Last post by Brian270 - May 30, 2026, 07:28:11 AM
Hi,
We converted our home from in floor hydronic to forced air which included running ductwork and installing a furnace/HRV/AC.
Looking back and doing research throughout, there were no manual J,D or S completed, it was designed solely by Installer experience and the least intrusive way to the home.
Now that we are at this point, I believe the only thing we can do to ensure the system is working optimally is perform a static pressure test for furnace efficiency and wait for winter to hope that we have appropriate heat throughout our home..
Everything I read, mentions checking the Total External Static Pressure with a monometer to ensure the system is balanced and not overworking the fan.
My HVAC installer didn't do this yet and we are ready to close out this install.
Should I request this test?
Thoughts please.
Cheers

Administrator... Thank you for the reply, that solidifies my thoughts from other searches.
Glad I stumbled across this forum and that you took the time to reply. Thank You!
I have read this same thing in a few places. I will show my installer this and hopefully he understands.
He's a reasonable fella and an awesome HVAC system installer just not big on the electrical part of things.
We are just finishing converting our 5 level home over from all in-floor hydronic heat to forced air. There where no ducts in the house so its been a big job but minimal intrusion because of planning and his critical thinking skills.. We are happy with this install but just the final details to button up.
I have one more question/concern I will post separately.
Cheers

I believe that model of HRV requires 4 wires for the interlock.

Quote3.3.2 UNIT INTERCONNECTION WITH CENTRAL FORCED-AIR SYSTEM (R/C/G/GF)
These connections must be done if you want the unit to force the central forced-air system blower operation when ventilating.
NOTE: These connections are required for installation confi guration T-4. Refer to section 2.2 for more details.

You connect the 1st wire between the R terminal on the HRV and the R terminal on the furnace.

You connect the second wire between the C terminal on the HRV and the C terminal on the furnace.

You connect the 3rd wire between the GF terminal on the HRV and the G terminal on the furnace.  Remove the G wire coming from the thermostat, that is already on the furnace G terminal, and marette it to the 4th wire from the HRV G terminal.

HVAC Help / Interlocking Trane and Venmar
Last post by Brian270 - May 29, 2026, 08:29:58 AM
Hi all, We just had a Trane S9V2 furnace and Venmar V130H65RT installed.
The HRV controller will make the furnace fan ramp up when choosing min, med, or high but I have to have the furnace fan set to on all the time for this to work.
If I set it to auto, the HRV will kick on but the furnace fan will not.
How should this be wired so the HRV controls the on/off and speed of the furnace?
Right now there are only 2 wires from furnace to HRV
Cheers

It's possible your gas detector meter is detecting trace mercaptan.

Why did Enbridge issue a warning tag on the furnace, if the water heater was the problem?  What Clause did they use?  And who cleared the warning tag on the furnace?

Without a manometer to test the gas piping system, you could perform a dial test at the gas meter.

Make sure no gas appliances will run during this test.  You may want to unplug the water heater.  Any standing pilot appliances would need to be turned off so no gas is being used.  Mark the 0.01m3 (metric gas meter) or 1/2ft2 (imperial gas meter) dial on the gas meter.  The dial on the gas meter should not move past your mark.  A hour long test should be sufficient.
 
If it does, there is a gas leak somewhere.  I would then turn the furnace gas shut off (on the gas piping) to the off position, and repeat the dial test.  If there is no longer a leak then it's likely gas is leaking past the furnace gas valve, out the orifices.
