Humidity issues with ducted Mitsubishi heat pump
Posted On: September 5, 2023
Hello, wondering if others have experienced difficulty maintaining comfortable humidity using a Mitsubishi hyper heat ducted system.
I think the heart of the matter is that they try to be too efficient and can maintain temp well but ignore the importance of humidity.
I have an old inefficient carrier ac downstairs which works great at keep the lower level cool and dry.
My upstairs unit is the heat pump.
I tend to use dry mode as it seems to work better than cool mode since it will try to run longer by keeping the fan speed low and the coil cold.
However, it only really significantly brings down humidity when it's first turned on.
And it does this really well initially.
It can drop eh by like 10% in an hour.
You can repeat this effect by continuing to lower the set point but then you just end up chasing uncomfortably cold temperatures to meet humidity.
If I set it at 74 it will cool until it hits 71 degrees, then shut off and kick back on when it reaches 73.
I could run a portable dehumidifier but they are loud, need to be emptied often unless you have a drain nearby, and consume lots of power.
If I could just hack this thing to run less efficient, ramp up the compressor hit a set point shut off and do it again I think It would be more comfortable.
Or come up with a way to schedule it so that the set point is at 74 then shuts off at 73, unit waits to turn back on at 75 and repeat.
Any thoughts or suggestions?
Thanks.
Question from user Ok-Swan2736 at heatpumps at reddit.
Answer:
Dry mode is 100% cooling.
It could also be that your unit is oversized.
You satisfy temp setpoint before pulling any moisture out of the air.
This is not the fault of your unit, but of your installers system selection.

I had a really great experience with these guys. The salesman Bob was clearly very knowledgeable about everything to do with heating and cooling a home, spent a lot of time with us going over the details of the job, never rushed us and came back after the install to make sure we were happy. The installation crew was excellent, they covered the floors all the way from outside down to the basement furnace room, kept the place clean, got the work done on time and were very friendly. Ive got 15 years in the contracting/ construction industry and these guys are one of the most professional companys Ive dealt with. Great company!

Reviews for Twintech were good, and they did not disappoint. After an initial visit to discuss the suitable AC unit for replacement, an installation date was available in just a couple of days, and everything was installed without a hitch. Highly recommended

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !
