We have an old RTU heat pump that needs to be replaced on our flat roof. It’s too bad Daikin doesn’t make a Fit that can replace a package unit. I was thinking that we could maybe install the air handler in a linen closet but that probably would be more trouble than it’s worth. We’re probably going to have to go with another package unit because the AZ heat is almost here. Do you know when the IRA rebates are going to be available in AZ?
In Arizona we install the Bosch Heat pump inverter because it qualifies for the $2,000 Federal Heat Pump TAX credit. We’ve actually installed a few of these and so far love them it’s a very quiet package unit and the only inverter package unit on the market currently (at least that I’m aware of). My understanding is the federal tax credit is active and available in AZ? I know the Bosch equipment qualifies for the tax credit/rebates from SRP and haven’t heard otherwise.
Honestly I don’t think regular txvs are reliable 😂… I’ve seen them have issues too if anything they’re more reliable IMO and easier to troubleshoot because the system just tells you a specific error code of what’s happening. Bad “analog” TXV is usually not the TXV and usually airflow or any other misdiagnosis but they still do fail sometimes
Short answer I wouldn’t worry about that at all because to date we installed our first Daikin fit about 6 years ago I believe and haven’t replaced a TXV on them once. But since then we’ve replaced at least a few regular txvs that failed
Hi HVAC Dope Show, love your videos. I had a quick question about high efficiency media/electrostatic filters. I'm planning on purchasing a Daikin Fit (or similar) system in 2025 after Daikin moves to R32 in the USA. I know, in general you like Daikin equipment. I also know, in general, most HVAC installers recommend 4" media filters over electrostatic filters (because most home owners don't maintain electrostatic filters properly). Specifically, for a Daikin system, what filter solution would you recommend for my wife and I? She has severe allergies. Needs to be MERV13 equiv or better. I think the Daikin filter is electrostatic, isn't it? Would you recommend it? Or a Honewell or AprilAir 4" media filter instead? Do folks ever install these AFTER the blower (aka in the supply stream north of the evaporator coil)? Or are they always installed in the return prior to the blower? My thought is that it would be "best" to have a 1" fiberglass filter before the blower (aka on the return side to catch the large crap), and then place the 4"/high efficiency unit on the supply side (after the evaporator) so that you're sure 100% of the supply air is being filtered. Or does no one do that for residential installs? Thank you, and keep up the great work! -Jonathan
Jonathan thanks for the awesome comment! Very thorough post and I appreciate the detail… short answer is we’re making another video about Healthway which is a Merv 16 product (same as an N95 mask!) and it’s electrostatic as well as hepa. Filters are pricey but if you want high filtration this is the best but they are massive and have a lot of surface area to capture particles. The short answer on two filters (supply and return) is it will be too restrictive you’ll never get enough airflow that way. If you really want high filtration a merv 13 filter box with 4 or 5” filter, or a healthway merv 16 product is your best bet for your situation. Thanks again for the comment, will use this for several great discussion topics in some upcoming videos
That was only on 1st gen at ambient temps over 115F. So it was really specific to being at 115F+ temps and high humidity where it struggled. Daikin Fit enhanced doesn’t have this issue anymore, great question
Could you talk about a gas furnace-based base-board system conversion to a heat pump system? Is this possible? Do the new propane refrigerant heat pumps have enough oomph to heat water to temperatures that can heat a home set up this way? Would so appreciate your intelligence and experience with this type of conversion. THANKS!
Only with R290 monobloc systems when they come to the USA but the Cop (efficiency) drops as the water temps get higher… So to mitigate that they’re most efficient with radiant in floor heating because in floor radiant is normally a much lower water temp (95F-110F compared to 180F for baseboards). They’ll be here soon I hope but no eta yet because of regulations
@@TheHVACDopeShow So appreciate your quick response and in-depth overview of where we're at. I didn't realize that radiant systems work at such low temps which makes me think about overall system efficiencies.
Great information. I wish you serviced the Houston area. I currently have a Lennox 5 ton, 21 SEER, installed Septemebr 2009. Looking at replacing with a Daikin Unit. The Daikin Fit 17 (5ton) w/heat furnace is quoted at $17,624, where as the DX 9 (18 SEER/5 ton) is rated at $30,129. We rarely hit 115 degrees , but often hit 110-112 and have high humidity issues. Do you see a benefit in the DX9 over the Fit 17 in the Houston market? Thanks.
Thanks for the compliment and we hope to service the Houston area hopefully by Q4 of this year, but in the meantime that sounds like a reasonable quote. I wouldn’t be concerned, there’s a pretty big difference between 112 and 116 even though it doesn’t seem like much, but the Daikin fit should keep up fine. Did the local contractor have anything to say? Just curious because they’re a local and normally won’t recommend or sell equipment that won’t keep up in the climate. The DX9 is quite a step up but I don’t know that you’ll recoup the price difference ever in terms of efficiency. Both systems have a 12 year compressor guarantee so you’ll be trouble free / under warranty for most of the life of the unit with either choice. We’ve had several Texas subscribers comment about how happy they are with their Daikin fit so I think it will keep up fine with the humidity. Thanks for the comment!
@@TheHVACDopeShow - thanks for the feedback. The contractor was leaning to the Fit 17, stating the DX9 wouldn’t be much more efficient in a 5 ton as, as you said, wouldn’t come l close to recouping the cost difference. What I find interesting is that this contractor states there is a 2 year warranty on labor and a 12 warranty on parts, whereas as second contractor said that there is a 12 year warranty on parts and labor and that Daikin will reimburse the contractor the labor costs. Interesting.
Hi. Building a new house in Miami FL (I asked a question before - same guy)). Concrete foundation, no basement, one-story house, attic space where in the highest point is 5’, house ceiling is 8.5’, 2450 sqf under AC. Main windows are facing south and north. House perimeter in built with 8” CMU (concrete masonry unit). We use furring strips to separate CMU with drywall. In between furring strips there is masonry wall insulation. We use impact windows which are thick and really good for sound and whether insulation. Currently looking at the Daikin brand, more specific an inverter heat pump. Additional information: I do have enough space for a traditional unit. In Miami the highest temperature is 97-100 degrees in the summer time but with 100% humidity. After listening to at least 30 of your videos, I think I am looking at the Daikin Fit Het Pump DZ6VS or the DZ9VC. Questions: what tonnage? I am aware that there are many variables that should be taken into account, but if we take that Miami is in zone 1 in the climate zone map, that I have 2450 sqf under AC and that I am dealing with a new construction with bran new insulation, what should be the system’s tonnage? Can I install the Daikin Fit Enhance version? Do I have use the Daikin One Touch for the thermostat? Is there any other alternative? I know that I cannot use the thermostat such as the Nest. Can I install the Daikin One Premium Air Cleaner with either unit? Any suggestion as the paring Air handler? Thanks in advance, your videos are extremely helpful. After obtaining all this knowledge I am ready to find a local contractor. The one issue is that when I look at Daikin’s website, there is one local service provider and they are located in Ft. Lauderdale. That is concerning the day that I would need service.
Yes on the thermostat you have to use the Daikin one / touch etc, your contractor should do a heat load and be able to tell you what size. Yes the air cleaner will work.
And I would think the Fit dz6 is enough and dz9 is not needed even though efficiency is higher only because the space is somewhat smaller. My guess is with a well insulated home like that you’ll probably have a single 4 or 5 ton? But again you’ll need a load calculation done… glad you found the videos helpful 😁
@@TheHVACDopeShow Wanted to thank you for all the content and you put out. As a home owner I feel very comfortable looking for the contractor that would do my work. Thanks again and I look forward for new content.

And yes the AZ heat is creeping up on us quick lol! Almost over 100 this weekend.
Is the electric TXV as reliable as the more traditional TXV? Looking at getting a FIT but not sure on the long term reliability on the electric TXV
Honestly I don’t think regular txvs are reliable 😂… I’ve seen them have issues too if anything they’re more reliable IMO and easier to troubleshoot because the system just tells you a specific error code of what’s happening. Bad “analog” TXV is usually not the TXV and usually airflow or any other misdiagnosis but they still do fail sometimes
