Daikin DZ9 🆚 Carrier Infiniti 24 SEER Heat Pump | 2024 Heat Pump Review

[@MFD541]

Update on our Diakin fit installation. They wound up installing the 3Ton 19.2 seer 2 D Z9 heat pump for the outside unit. So far we are liking it. Not super happy with the Diakin one thermostat, The room thermometers show 77° and the diaken. One thermostat shows 73 degrees. Runs super quiet and so far. Using about five dollars a day in electricity here on the border, south texas.

That’s awesome, the issue with the thermostat is calibration. In the installer settings you’re able to set the thermostat temp based on other thermostats. Same thing happened with mine, I think it was off by 2 or 3 degrees. Once we calibrated it to match the other thermostats it will stay put and be accurate but I’ve seen this first hand, simple fix

This is going to be a long comment; I’m sorry! I live in Albuquerque, NM. My house is currently heated by a 5-ton Train 80LX that is about 25 years old. As for cooling, it uses a Mastercool AD1C71 7000 Cfm. The house was built in 1972 and is about 2500 Sq. Ft. I currently have 39 Panasonic 350-watt solar panels and a Solaredge 10,000kw inverter that power the house. I currently use about 800ish kWh a month, but I generate 2 to 2.5 MHh a month. So I’m dumping a LOT of power back into the grid. I only get paid 7 cents on the dollar so it’s in my best interest to use my power first. OK with that out of the way I’ve been wanting to upgrade to a heat pump for both cooling and heating. First, I want to ditch Gas as I still have to pay for that, second, my house (being built in 72) is already an energy pig and I’d like to make it more efficient. I have been getting estimates on a central heat pump system. Compressor and air handler downward flow, closet is in the center of the house. The estimates have been ALLOVER the place from I need a 5-ton 24 seer, plus heating strips, plus hybrid gas furnace, and 3 220 lines with a 44K price tag. To a 5-ton 18 seer no heating strips are needed but it’s going to eat 17 panels worth of energy, but will only cost me 18K. To a buddy telling me to just get a unit online (he suggested a 5 ton 20 seer Rheem/Fujitsu currently on sale for 6500) and with KZbin’s help we can install it. They all say a heat pump won’t work if the temperature gets to 40F or lower and I need, anywhere from 10Kw heat strips to 25Kw heat strips. SO I AM TOTALLY CONFUSED! I thought heat pumps were more efficient than I’m being told! Do they really need 3 220-volt lines pulling 180 amps?! That sounds OUTRAGES, and not that efficient at all! Last summer I ran 5 10000 BTU window ACs to cool the house, you can’t tell me they are more efficient than a heat pump! So I need some advice, what do I believe? What size and seer Heat pump do I really need? Will it work in 40F weather? Do I need heat strips and if so what type? What would be an honest estimate for an installation? I really hope you can help me out on this one, I’ve talked to 23 companies here none of them say the same thing. THANK YOU for your time and consideration.

What’s are your thoughts on the Iwave air purifier . Would you put one in your home ?

[@MFD541]

Get the Nushield-R i, it Meets the new UL 2998 Zero Ozone Emission Certification. less ozone is better.

[@TheHVACDopeShow]

Ozone is somewhat controversial but it definitely is shown to affect people with asthma or sensitive respiratory systems. Besides that it does make the error feel “fresher” and I haven’t personally had any complaints on them, but we make it a point to advise other ozone free products in instances where people have sensitive respiratory systems.

[@TheHVACDopeShow]

And short answer is yes I would put one in my home, I haven’t yet but I’ve been happy with the air quality so far. I think it would be worth it for homes with large families because of germs from people getting sick etc, it would help keep the airborne viral load lower and keep people healthier in that respect.

I have a unique situation and found a few of your helpful videos. We moved into a new home in the Pacific Northwest. It's 9 years old, 2,900 sq ft and very modern in design with lots of south facing floor to ceiling windows. The problem is: 1. The 12" ductwork is undersized and limits us to a 3 ton unit (according to the contractor) 2. The heat gain from the southern windows will make the home 90 degrees inside when it's 45 degrees outside (we have blinds to help). 3. A ductless mini split would be extremely challenging due to the home's conditions Would Swapping from the current single stage AC to the Carrier 24HP get us any more cooling capacity since it could run continuously, rather than the on/off of the single stage? Is there any suggestion you have for this challenging situation?

[@TheHVACDopeShow]

Modify the ductwork to accommodate the load, or a mini split is a good option. Swapping to an inverter just means your running the AC for less $ but you really want to fix the airflow issues first anyways… not sure why the contractor doesn’t want to address airflow unless the ductwork is inaccessible which does happen and can make things difficult

I want to replace my HVAC in my miami condo in miami florida. 1500 square feet. The ducts already exist and there is space on the roof for my existing HVAC. BUT, I want to change the HVAC to a Pancake style because the condo was built to have a pancake. I am most concerned about dehumidification in the summer. I leafe the doors and winds open during winter. What do you recommend?

[@TheHVACDopeShow]

Would have to look at it to understand exactly what you’re referencing but if you currently have a “pancake” (first co unit?) air handler then getting a new one and pairing it with a different condenser on the roof is probably fine. Are you saying you have a different setup currently like air to water heat pump / central chiller ?

23 SEER2 😳 Dang it, just ordered two 20 SEER1 ACIQ’s 😫

[@TheHVACDopeShow]

Those are nice systems for the price, I don’t know that you’d notice a difference between these

[@michaelhatfull3305]

@@TheHVACDopeShowhuge difference with the humidity control in this. Please make sure you tell them correctly.

[@Litt1leMe]

To funny, I've been looking at these two. The only reason I haven't jumped is because of the new coolant standards.

[@TheHVACDopeShow]

Right on yeah we’ll have some new vids on those soon when they’re here!

We switched to Daikin a few months ago at our company. I’ve never seen so many failures in my career. Roughly 90 units installed and we’ve had 60 failures I. The first week. Swapped 4 units out completely. Worst decision we ever made. Going to carrier

[@TheHVACDopeShow]

That’s a lot of failures and we haven’t had that experience, I would rule out installation issues first because half the times callbacks are preventable issues like sizing or just small things that were missed (cardboard tab in a condensate pump)

[@rickybobby6386]

@@TheHVACDopeShow clogged coils from factory, 2nd stage compressor connection plugged in sideways, handful of bad compressors.

[@vbl20012k7]

Wow, 60 of 90 installed units failure is ... a really bad. I intend to get Daikin heat pump, but I may change my mind to switch to either Trane, Mitsubishi or Fujitsu.
