will the scanner bring the rooms together automatically of do you bring the rooms together manually?
Automatically!
That’s a good point. Usually if you seal up just a few of the biggest leaks in the building, then it brings the latent load down a lot! The first house my wife and I bought, it had high humidity. As soon as I started looking around I saw gaping holes around the plenum going into the attic. That was actually most of the issue. I sealed that massive leak, and did some air sealing on top plates in the attic and the results were great. No humidity issues so long as the air conditioner was running. Later, we added a radiant barrier and tinted one south window, which decreased our heat load approximately 10% in that home. All this made the temperatures through the home more even, and the humidity was nice and comfortable. I did set up a relay on the air handler to dehumidify with a slower fan speed for mild days. It really helped. The ecobee controlled that. I wheeled out a portable dehumidifier at times when no a/c was on for long periods.
Great video again
Awesome!
Amazing video. I did so much Googling and nothing was as good as this. Thank you amazing person!
@@doccock1662 thanks!
Hello Tim, great information that you share with us. Where can I get a psychrmetric chart with the necesary info for AC application big enough to plot and play as you do in the board. What I found has to many info that is really dificult to see. Thank you in advance
@@germanagudelo6533 i havent found one yet either
This is great. Thankyou
Tim, loved your UDEMY course. Any plans to do more on HVAC? Blessings from Canada
I am developing an HVAC Fundamentals Course through Course Careers. It should release sometime before March. Thanks!
Hi Tim, thank you for sharing your knowledge and experience. I would like to have an idea of how much do you charge for the comfort consult and how many different services within the service you provide and its prices. I do energy audits over here in Dallas, Texas area and there are many customers that want the service but not willing to pay not even for the trip. Any advice is greatly appreciated
Here on the coast, there is a pain point for moisture problems, rot, mold and discomfort. I avoid using the word "Energy Audit" because it doesn't address any of those pain points. If you only approach your service from an energy perspective, people quickly realize they'll never get an ROI. Currently, I am getting $1500 for mine for a small home. If goes up from there. Not everybody is going to pay that. Focus on the communities that can or offer a financing package so they can afford it.
@timdestasiohvac Thank you so much
As always nice video again
thanks
What do you tell the customer when you find the home performance problem, when the system isn't necessarily oversized? Is that something that we can fix as an HVAC tech?
Great video definitely will help with the summer setup. I know people have asked but could you show us the heat settings. I'm sure with this winter blast we all could use the proper setup.
Just saw your video with Corbet and was impressed with your info. Retired/disabled Contractor from SoCal/NorCal moving to Jacksonville, NC and need to relearn HVAC concepts(HUMIDITY). thanks. Brian
You're welcome. And welcome to NC.
Take care of them you will miss them when they are gone!
Is this the same oem unit as the Fantech? it looks nearly identical
I don't know.
Fantastic video Tim. You have a way of making learning easy and fun. You buddy. Donald from DuctScience
Thanks my man!
Thanks Tim. This should be required viewing for HVAC techs.
I think so too!
My question is, if increasing the fan speed gives us the airflow needed with a higher static pressure, what is the problem that will occur, besides noise? Great video!
High static consumes more wattage, reduces ECM motor lifespan and can push/ pull condensate out of the pan and trap causing water issues.
@timdestasiohvac Thanks for the response. Makes sense to me!
Really wanting to buy a true flow grid to get the information it provides. I like and work in charlotte. What you found at your parent’s home is not uncommon. Here’s my issue/question; what would I do when there are 2 or more filter grills on the one system?
@@kevinjohnson4966 True Flow has a workflow for that.
My minisplit is pretty high ( 10ft ) so its usually reads almost 5 degrees warmer than the actual room temperature..will this smart thermostat correct this ?
@@itscard0man yes it will!
My installer wired W2 and theres no Y2 wire. Should i be concerned? Everything works.
Forgive me if you already have a video on this, I’m exploring my new build home and don’t want to break anything/be inefficient. My defusers all have flaps under the vanity vents, all flaps were in the shut position and bathrooms even taped shut covering half the flap any input is greatly appreciated just don’t want to hurt my system but I do want more flow with less hissing
Definitely open them up. You aren't going to hurt anything.
Nice job I have been using wrightsoft for almost 20 years now. Is amazing how far it's come. It takes some time, but you can remap your equipment, duct, fittings, and registers with current parts from your supplier. you can even attach pricing and labor hours so after your done with the draw you have a material list and even a proposal including parts, labor, and mark up. Save's a ton of time.
@@prestigehvac4538 they just had a big update. New look and 3d viewer added.
Quickly becoming one of my favorite HVAC tools!
Mine too man!
Great upgrades to what was already an invaluable tool.
Looks like a great tool. Need to do alil research. Buying it is alil confusing. Tools pretty pricey plus there’s like 10 adapters plates $98 a piece. Is it best to buy the tool and all the adapters?
@@TheBattery00 go to TECs site and use code TD2025 to save 8%
Great stuff! Thanks Tim.
Awesome demo and jealous of your blower door CFM number! :)
You don’t need the supco meter, your field piece allows you to test the seer rating on any unit
@@BryanLopez-wt4py which model
I found this video by accident, maybe because the facility I work at needs extremely dry air below -20 deg F and moisture is measured with PPM by weight which is far beyond the needs of typical HVAC. I have read and felt that adding humidity can make the room feel warmer, reducing humidity can make it feel cooler for a given temperature. Anyway this SHR concept is new for me. From various analysis and papers i.e. equations by Arden Buck. It seems these and the psychrometric chart you show is all based on the work by Goff and Gratch in 1946.
Good stuff! I never saw anyone explain SHR like this, mapped out and showing a target quadrant.
It’s a constant battle with load outs between too much/too heavy vs. that extra trip back to the truck. For AC/Heat pump I actually went lighter with 2 mb3's-one with tools for diagnosis electric, and the other with all the probes. If the call is an obvious electrical issue, I can leave the probe bag in the truck, otherwise it’s easy enough to carry in both. The other conclusion I drew regarding carrying less, is there are only a few things you can actually fully repair without making a return trip to the truck, so why bring the whole kitchen sink? So I made up smaller grab and go 'kits' for specific tasks that have all the tools/parts to complete that task. Motors kit, pvc/drain/condensate pump kit, copper tubing kit, sheet metal kit, etc. I do end up with some redundant tools, but that just means I get to buy more tools…:)
@@HVAC_Tips_Tricks_Calcs good plan
Any time you take something out you will need it . Nice load out
Most of the time if the air conditioner is working contractors don’t care about the rest of the home in my experience. But, that’s why I have a fun job!
Now you need to have a video series explaining how to troubleshoot systems using this.
For some reason your audio is only coming out of one speaker. (The left side works for me, and the right side is silent.) I just checked the speakers with another channel, so it's definitely this video.
I experienced the same as I watch while wearing headphones
Hell yeah, Thanks Tim!
An excellent video. It’s about air flow folks, a quality healthy air.
I basically have the same setup. What settings would you recommend for running heat on the ecobee? I seem to run into a problem where my heat pump is blowing lukewarm air and runs all night.
Well my mr cool system forced hot air it has a dehumidifier and a humidifier
@@mechanictaft4848 lol oh really? I definitely sense an abundance of hot air lol.
Thanks for your video ❤
Another nice video man as always I like to see it . Thanks
@@chesstime356 thanks man

Excellent information and presentation. Have been installing the A and B series for only the last 2 years in Northern California and set them only in AC mode only. Stilling learning through trial and error but I do agree with all your points. Keep us updated with new videos on future Bosch issues or repairs you encounter.
@@TheRealoldcar thank you
Another nice video Tim! I like the thorough simple explanation. Well done.
Thank you.
Thank you.
We love the Bosch, Philly has humidity but nothing like the Southern areas. The IDS lite is a great entry level product. We've had customers floor by the difference in sound level outside and electric cost to run the unit, coupled with comfort of a continuous flow of heated and cool airflow. The 20 seer high heat model in a cold climate cannot be beat. Previously we used Daikin or Fujitsu compact cassette blower mini split ducted units, which can work with existing duct system in some cases. Unless the existing duct system is a complete mess, Bosch will work. However, the use of Aero Seal process might be required.
@@dennistreacy3595 great comment!
I actually did my own ducts after watching a you tube video. I was able to do a DIY setup that worked pretty good! My return vent had so much collected dust in it, it looked like grey insulation. Every time the unit would come on we would start sneezing (this is a rental Condo)! The blower fan and coil had a lot of debris on them, it was a mess! After cleaning every thing; not only was there an immediately difference in the air quality. My electric/heating bill went from $270-320 a month to a steady $170-180!!!!! I have since placed a filter over the air return vent which I change every 3 months. Never had to do another cleaning and that's been 4yrs ago:).
The company I am with has been installing Bosch IDS systems for about 8 years now. We love them, amazing reliability, and amazing performance when properly sized and set up. We do not flip the switch, in 3 different Bosch classes we were informed it is simply not needed, one of the head instructors stated he doesn't understand why its even present, as its not needed. We mostly use the Bosch BCC100 thermostat, but now switching to the Bosch BCC110 as its replacing the BCC100. Bosch will work with most heat pump thermostats, we have also used several Honeywell models, along with PRO1. Ecobee is the only thermostat that has given us issues, and a Bosch rep I spoke with said it was a conflict of interest, as the Bosch board is trying to maintain constant coil temp, and the eco-bee using geo-fencing is trying to limit compressor run time based on occupancy, setpoint, runtime, etc. thus a conflict of interest. Now kudos to you if you have eco-bee and Bosch nesting together perfectly, (we finally resolved out issue after several callbacks ) so yes properly set up ecobee and Bosch can play nice together, but I will stick with Bosch's thermostat designed for the system and plays nice from the start, and continue to use PRO1 stats in the dumbed down configurations. Hope I didn't sound harsh, was a great video, I subbed, look forward to more content from you, and of course offering my .2 cents. Have a Merry Christmas!
