- In this Video we go over a Mitsubishi SUZ/SVZ Combination installation. WIth efficiency ratings and a pricepoint that is hard to beat, this product is a fantastic middle ground between a single stage system and a fully variable speed system.
Wow an actual clean install.
Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) czcams.com/users/postUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.
beautiful work boys, This is exactly what I was looking for to see how a proper and professional job should be done. Nice to see the decible reading with the isolation mounts!
Damn, cleanest install I've seen 👍
Nice installation.
Great work! Very clean installation inside and out!
Looks good nice install, wonder when I can use heat dumped outside by compressor to heat water?
Thanks for providing the decibel on the outside unit. Any idea about the noise generated by the air handler inside? Also is the air handler a variable speed unit?
Great Install and love the finish product!
I am also having increased electric bill with these units.. This is my 2nd year now.
1- PUZA36NHA7 Hyper Heat Outdoor Condenser
1- PVAA36AA7 Multi Position Heat Pump Air Handler (1st Floor)
1- PUZA30NHA7 Hyper Heat Outdoor Condenser
1- PVAA30AA7 Multi Position Heat Pump Air Handler (2nd Floor)
Last year my electric bill went up to $1,160 in the winter and in the summer my bill is low as $176. I had the HVAC servicing team come many times to trouble shoot this unit.
We set our temp at 70-71 degrees in the winter. We notice the unit is constantly running to maintain the temp. the outside temp is 32-36degrees today and I feel like the machine was running most of the day. (70%) The service tech is saying to get heating strips and this way machine wont work as hard. But that is another thing going on the grid which will increase my electric usage. Any thoughts or suggestion?
Troubleshoot:
Did a blower door test to detect any leaks, and I passed.
Check refrigerant levels to ensure no leaks- passed
change air filters-
ask them to do another heat loss calculation. I was told the im oversized for the house by 7
Please help!
Hi there. Looking to transitioning to a heat pump. Do you mind sharing your approx. location, house size, and heat pump size? And why do you have 2 heat pumps? Thanks!
These are precision charged machines. If the charge is overcharged or undercharged they will use more energy. Possibly the system is not sized correctly for your home. $1100 is VERY excessive as these systems are extremely inefficient. I’d call a different service company with more experience/knowledge to troubleshoot. They can actually measure the kW useage in real time. Also, the other question is how is your window quality? What about insulation? Is your home losing more heat than the system can transfer?? These are all questions as your whole home is a system, not just the machine
Great video. Agree that would like to see ducting.
What size line set does that have. Thinking about installing one in my home, installing a new lineset won’t be easy. Just wondering if I could use the old one and just flush it.
Great video and thanks for sharing. Would you recommend moving to this electric unit even if you currently have natural gas in the home?
Yes. Many people have done it. You don’t need it. That’s a heat pump hot water heater as well next to the unit. Save money by not lying for gas. Save more money by getting Tesla solar.
Awesome would have been nice to see the duct layout though
Yup, thought the same - also, would have liked more detail on the upgraded filter. Gave them a thumbs up non the less.
Unclear if house location in snow belt as outdoor unit does not meet most codes for ground height clearance for snow/ice. Why a return plenum in attic??
Is that product special for the US market from Mitsubishi Electric?
I just installed a mitsubishi 4 ton hyper heat unit with 2 air handlers. We're still under construction but my 1st electric bill came in at $285. I pooped my shorts when I saw that. Compared to the $103 gas bill at the house we are currently in. I'm hoping I didn't make the wrong decision in the long run by going all electric on this build.
John, I am just wondering if that was above what your normal electric bill is at your current place. My house is all electric-a mobile home-at 1865 sq ft, with no heat pump systems. That $285 is my electric bill in January and February, using a propane stove to supplement on colder days (at about $28 a week). Hopefully, your bills go down significantly after your construction is complete.
Hi John, lots of factors go into heat pump system design. If you are on natural gas and depending on the size of your home, it is possible that it may be cheaper to Heat with gas by a small margin. Every home is unique In the amount of heating or cooling it requires and factors like climate, utility company rates and indoor temp setting play large roles in the effectiveness and payoff of these systems. Hope this helps!
From everything I've seen, natural gas is probably cheaper than heat pumps whenever the COP drops below about 1.50 on the heat pump. That varies but could be 10-20F or so. Disable the hyper heat or backup heat though unless you really really need it.
@@matsudakodo yeah I flipped the breakers on the backup heaters.
How have your bills been since?
How many BTUs is this unit for heat
Thanks for sharing your experience. I am also looking to replace my aging central hvac ( NG/ AC ) by such a system.
what is the model and size of this heat pump / air handler combo and what home size it is heating / cooling in which climate zone ? Will it be possible to share some data on its electricity consumption ( KwH ) while heating ? Is the efficiency close to COP of 3 with ambient at 35-40 F as claimed my Mitsubishi for their ducted system ?
I have a 3400 sq ft home - two level - with good insulation in Bay Area, CA. I am looking to install two 30K BTU ducted Mitsubishi heat pump. But I am super scared of running high electricity bill as it is very expensive here and hence, my request for sharing your observation of KwH uses and COP of these systems. Thanks.
I would suggest watching the video Technology Connections did on Heat Pump systems. In many cases, Heat Pumps perform as well if not better than conventional furnace systems.

Do you install hvac in Florida?
What does something like this cost?
Hello there, With this combo what type of thermostat did you used? I am planning to install the same combo and home owner wants Nest Thermostat. Can you recommend using the Nest with this setup?
Yes you can but you have to order the transformer that would be built into the Mitsubishi unit.
Would that set-up work with an 1865 sq ft mobile home for both the heating and water heater? My ducting is in the crawl space, with the cold air return in the ceiling. I live in Sequim, BTW.
Hi Kris, this system is great for a manufactured home, and dollar for dollar is likely the best heat pump system you can get for reliability, comfort and noise. I hope this helps!
Hey guys, a couple of questions. Why is the air handler upside down? Not criticizing, just wondering, and would adding an extra filter not cause restriction to the air handler which was designed with the restriction with its own designed filter?
downflow unit
What the unit cost? Install cost? Location? Btu?
At what outside temperature do you guys still work on the outside unit? TXV ,reversing valve, those type of repairs. Do you make the customers shovel the snow around the unit or do your mechanics shovel the snow also? If you lose power for a day or longer how long do you need for the crankcase heater to be active before starting the unit back up?
Oddly specific questions...
So specific questions seem odd to you. Obviously you don't do this for a living,@@redsadventures5654
Great job! What brand of surge protector is that?
Intermatic AG3000
Do the mitsubishi splitter/ junction boxes turn coolant off to unused units, or does it simply split it?
I have noticed on my system (2 air handlers) that if I have the first floor on heat and the second floor on fan, the second floor unit still continues to produce heat? Is there any way to fix that? Thx.
No good way to fix. In heat mode, refrigerant will be sent to both zones. In cooling, it will only send refrigerant to the zone that is calling for cooling. All brands do the same thing unfortunately!
@@marrsheatingandairconditio5891 Thank you, that's what I feared.
@@marrsheatingandairconditio5891 Isn't this a Mitsubishi VRF system where there is an expansion value on both indoor units/air handler, and also on the outdoor heat pump so that it can control the temperature individually and more precisely for each indoor unit?
I-wave is supposed to be installed on the return side of the ductwork (;
We certainly try to do that to treat the coil. We really added this last minute and due to the unit width we didn’t have room to install in the blower compartment. We also didn’t want to install before the filter. The good news, our climate is very dry, so hardly any latent load type issues, such as coil growth. But yes I agree, coil should get treated!
Fail on protection needs ICM493
How much ?
So the heat pump water heater refrigerates the garage while you are trying to heat the house? Kinda dumb.
cameraman should've been in front of the camera instead of Kyle. Kyle was doing just fine
What would be the best thermostat for the intelli-heat and gas furnace setup you would recommend?
How much?
I'm in Northern California, and I got a quote of ~$20K with this system (1 SVZ indoor air handler and 1 SUZ outdoor heat pump), but also including electronic dampers for the ducts to zone both levels.
@@stevepon7810 Phew, that was for just installing the unit?
