For any homeowners out there who are looking to replace their own ERV or do a DIY install, I would highly recommend the Broan AI Series ERVs. I just replaced my old, non-functioning Honeywell unit from 2002 with a Broan AI Series. I inquired with many different HVAC contractors about ERVs but all of them told me something along the lines of “don’t see the point in them as it’s just the equivalent to opening a window.” I’ve been watching Matt for a while so I knew this wasn’t true and that my builder obviously put one in for a reason. What sold me on the AI Series is the unit uses an auto-balancing procedure. Meaning, no need for a manometer, pitot tube, or having to manually adjust dampers. The unit has integrated motorized dampers and displays the incoming and outgoing CFMs. It also comes with a MERV 8 filter standard, upgradable to MERV 13. I looked at a couple different ERVs from Zhender, Honeywell, and Aprilaire. The Broan AI series sold me instantly for the reasons above, specifically the auto-balancing. The AI series also just looks likes it’s modern technology, compared to other brands. I’m really happy to have my fresh air system functioning again and even more happier to know I did it myself, saving thousands of dollars. I just need to wire the Broan touchscreen keypad for it now in my upstairs so I can monitor the status of the unit.
Im so glad I found your channel! I've watch so so many in the last month or so. I just love watching your videos, so informative and entertaining. Makes me want to build a new house. I just got an HRV and use it to exchange the air in my basement only. It put my Radon levels from over 8 to around 2 and under(it fluctuates a little). Also, I use the stale air exit from near the cat litter box which is also in the basement, so win win!
You didn’t scream, “on the build show!” I’m shocked! 😂 Thanks for another great video.
Interesting choice of install. I'm in northern ontario. I prefer to see the HRV supply dump into my furnace return. I also prefer to run my furnace fan on low at all times to maintain a better air blend across the floors and to allow the hrv supply to blend with the furnace/house mixed air. This also allows the hrv supply to always be distributed throughout the supply ducts reaching all areas and rooms. In the cold winters it's also nice to have the hrv dump into the furnace return to further condition that air to a comfortable temp (important to have the furnace fan on to achieve best results ducting it to the return, works as a whole home air handling system). Different climates do allow for a different install, being it's an ERV its differs slightly too.
In a more extreme climate where you get 100° summers with 70-90% RH and 5° winters dumping the ERV supply into the furnace return is a must. The supply air from the ERV being concentrated to a hallway will make that hallway very cool or very warm and muggy at the peak of the seasons.
If you bring in warm humid outside air to the ERV - exchanging with air from the bathroom and kitchen, is that not counter to the units function, given the bathroom/ kitchen air has a level of moisture. Perhaps waste outgoing air should be picked from a dryer area of the home. The unit is depending on clean dryer air to treat the incoming humid air. JAT
Thanks Matt!
On my shopping list! Thanks for great insights... as usual... Matt Risinger's standard.
I really need one of these. I have a brand new 900 sq ft home that is super tight. I often leave a window or door cracked open.
Matt, nice video I always enjoy watching them! You mentioned 3-4 feet between outside inlets, most other manufacturers of HRV/ERV recommend min. 6 foot apart. And I wouldn't even consider a connection to HVAC system at all, balance is almost impossible. I learned that the hard way!
Love his voice.
Hello, it’s a really good video. I gained alot of knowledge. One question rises. If you were to use it as stand alone unit, would this be the only source of fresh air to the house and your furnace will solely be heating up up cold air return?
Nice review! Does this unit have any sort of relay system to trigger increased intake when stand alone stove or bathroom exhaust fans turn on? How do you handle that?
Matt, Great video as always. I am wondering if you have ever installed this unit laying flat on the back cover vs chain hung or wall mounted. Panasonics literature doesn't say anything about whether you can do that at all.
Ha Mat what do u have anything for outside wood Boilers to heat ones home through HVAC an Hydronic flooring this time of the year
How much does that odd sized pre-filter cost to replace and who stocks them?
I saw the duct work you were using and I would not have it in my house. I took out all the flexible duct work and replaced it with rigid. Stays cleaner, less opportunity for mold to grow; and of course, when it comes to cleaning the ducts it is much simpler and thorough. When I bought my first house in Ohio I was flooded in 2003; not a problem of building but when you get 14" of rain in a week and then 7" in 45 minutes you are going to have a problem. When the rain stopped, the water left my property (1 1/4 acres) in less than 45 minutes - a new respect for moving water! During the flood, my basement (1,796 sf.) went from bone dry to 24" of water in about 15 minutes; the water came in through the basement windows and was strong enough to move a 5 gallon bucket of horse shoes and stakes the full length of the basement. I spent the night pumping out and was ready for the clean up crew the next morning. They started by putting two huge dehumidifiers in the basement and then on to the second floor and cleaning the ducts. They commented that it was good to have rigid duct work - much easier to clean. Then back to the basement to cut a large hole in the duct work and send their brushes up. Then shut everything down and leave the house for an hour while all the ducts were sprayed with a biocide. Repeated with another two days later that allowed us to stay in the house but with all fans turned off. Then the basement was dry enough to power wash the basement floors and walls half way up. Had to empty out the basement of furniture I was storing for my daughters (two houses worth), filled a 40 yd. dumpster and finally a new coat of paint on the walls and floor.Every house I have owned has been drained to daylight. This house has the strangest waterproofing system I have ever seen. The foundation was sprayed with hot tar, then a fiberglass mat was put over it along with a second coat of hot tar followed by 4" of rigid foam insulation. The inside is painted with two coats Ultra DryLux and then painted with a highly reflective SW white paint. The floor was painted with SW concrete paint. Fifteen months, no dampness, no dust. Whoever had this house built did it right. Even the crawl space has a 4" concrete floor!
I installed this 7 months ago - Minnesota residence - it’s working great - even in the cold temps we’ve been seeing. During most months it’s been on 60/60 minutes an hour. When really cold we knock it back to 20 every hour. Big difference in allergies, build tight ventilate right
The Panasonic ERV looks like a good product. Interestingly, the inlet filter looks exactly like the cabin filter in my Toyota Tundra. One might be able to get new inlet filters for this Panasonic ERV at Autozone.
You have no idea how valuable this is for a mushroom farmer
