As a 25 year install, all furnaces have issues but the majority of issues i see is lack of maintenance on the homeowners part. Those two points are 100 percent the cause of most issues
💯😂 very true… that’s why we only install high efficiency furnaces when homeowners are aware of the maintenance and understand the damage basic things like not changing the filter will do
A few years ago I asked two great service techs if they would install a high tech furnsnce in thier own homes. Both said no. A million dollar house that I wired up had 2 by 6" fully installed exterior walls and over R50 in the attic. HVAC company talked him into installing two high tech tech jigh efficiency heat pumps. ( One fir tirst floor & other gor sevond floor). House had natural gad for the emergency backup. First year under free warranty both heat pumps broke down. Second yesr same thing but it cost him slmost $500 im labor. I told him to just run the jouse on nstural gas and next three years did not have any cold weather ecoensive setvice calls. Running on gas was chesper over all & s lot more dependable.
So high efficiency furnaces break because installers are unable to read and follow the installation instructions. I'm glad none of that applied to my two DIY installations in 2008 that are still performing flawlessly, after replacing only a 12-year old ID fan that became noisy. Oh, and put bird screening on both vent pipes; bird beaks in the ID fan stopped one of mine from turning, found and corrected at the beginning of a heating season checkup.
@@chadschafer3890 Not so for Goodman which provided an intake screen. I drilled holes in a cap to make a duplicate for the exhaust, rather than use an open tee. Use of nothing, as in the video, invites trouble, as I found out with two birds entering my 2" pipe and navigating two bends to the ID fan to die.
@@robertmeredith3940 There's a reason the didnt include one for the exhaust. Its not because they ran out of them. Again feel free to read the manual before you have no heat one day and wonder why
@@chadschafer3890 I did have no heat one day - because I had no filter on the exhaust. The furnace has run for about 12 years since then at temperatures down to -10F with no problems. No regrets. No more bird problems. Your choice.
Robert I don’t disagree lol… idk what the manual says for each unit on the market off the top of my head but we have less issues with birds / rodents etc (or toddlers… I’ve pulled toy cars out of exhaust before lol, the parents loved that one) but that’s why I prefer to put screens on them. Less callbacks
I've had a 95% unit since 2016 and it's been great once I got the installation issues fixed. Definitely less forgiving than the 80% ones. Still, it has been good overall and I hope they get even better. My gas bill reduction has practically paid for the entire unit already. Thanks for the video!
Right on that’s great to hear! It’s all about taking care of them and a proper install… sometimes there’s a few kinks to work out in the beginning but glad you’re enjoying it :)
Kind of off topic, but could you explain altitude derate for heat pumps? I have a Mitsubishi PUZ-HA30NKA1/PAA-A30AA1 and am at 5800ft (COS). Does this mean I'm really only getting ~24K BTU from my condenser? Thank you!
My understanding is that it technically has to do with airflow not the capacity of the condenser, since the refrigeration circuit is sealed the condenser itself doesn’t derate. At 5800’ you’re moving about 15% - 20% less air than Sea Level so the derate is based on CFM of air coming from the air handler / head unit inside, so the actual output is effectively lower because airflow is lower. But often times the head units can move more than the required minimum per ton of cooling/heating so sometimes with the settings and airspeed adjustment you can counteract this

Yikes… that’s different than high efficiency furnaces but sounds like an issue that should have been caught under warranty.

well if you read and followed the that same install manual you would see putting screens on vents is against their rules
