Humidity issues with ducted Mitsubishi heat pump

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.

Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!

by Private User from Bowmanville on Twintech Heating and Cooling

Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.

Twintech installed a Goodman furnace and ac init. Very professional install, both units are working well.

We had Grant and Greg Dainty quote to replace our 20 yr old furnace. I have known them for years and have had other jobs done by them ( AC and Pool Htr). The price was very reasonable and the job was completed in one day.

by Rick. F. in Pickering on Twintech Heating and Cooling

TwinTech was the right choice. Our consultation with Dave set the tone. Professional and knowledgeable, we even received a follow-up call within hours of our install completion, wow! TwinTech arrived as scheduled to install our A/C unit. Within minutes of arrival Greg noted and explained a few out of code faults on our furnace installed by another company, problems fixed, thanks TwinTech. Greg, Grant and "Subaru" Pete were meticulous start to finish. Highly recommended!

Twintech replaced our aging +20 yrs old Furnace & AC with the variable high efficiency Napoleon Furnace matched with the Goodman AC. Sales guy ,Dave was great, gave a no pressure estimate, explained about the Government Rebate program which they took care of completely including arranging the home energy audit. On the scheduled day Greg and his team arrived on time, did a great job and completed the same day , extremely professional and courteous, cleaned up everything , tested the system, Greg took his time to explain the setup. Very impressed with the Napoleon Furnace 9600 which did a great job in maintaining a comfortable temperature last winter and now with the hot weather the Goodman AC cooled the house in much less time than the old AC unit could ever. From start to finish Twintech were great and have no hesitation in recommending them 100%.

by Private User Pickering, ON on Twintech Heating and Cooling

The Twintech team did an excellent job installing our new Goodman air conditioner. They were polite and professional. Greg was knowledgeable and clearly experienced. Thank you Twintech for bringing our cooling system up to current regulations. Job well done!

by Y. M. from Pickering on Twintech Heating and Cooling

Dave from TwinTech was very knowledgeable, professional and thorough in the buying process. He helped us to identify the best furnace for our home and our budget. When we needed a new filter a year later and seemed to have a problem finding the right one, I called Dave up and he delivered a filter to me the next day! The cost was on par with other retailers, but it was this unexpected personal service that really was impressive. The furnace? Works like a charm.

by JLH from Pickering on Twintech Heating and Cooling

Imagine, it's 5 minutes after the midnight countdown New Year's eve and the furnace quits. We called TwinTech fully expecting to leave a message and actually spoke with Greg, one of the owners! We had an immediate repair early the next morning & a new furnace within the week. We have entrusted TwinTech with all our home HVAC service needs for over 6 years. That's why this week with an opportunity to purchase a new BBQ, we called them 1st to see about a gas line install. It's chicken on the grill tonight! They are efficient, reliable, honest, hard working, and -- attentive is an understatement.

by Curtis, Ajax on Twintech Heating and Cooling

Wonderful customer service, starting from the job quote (Dave), to the clean install, to the follow-up. Twintech is a small company which installed my Napoleon furnace, A/C, John Wood tank, and ran the line for my gas dryer. The installation was completed as promised in one day. The work area was kept very clean, and they even took care of my old rental tank. The professionalism and wonderful customer service is second to none. They completed all of my rebate paperwork, and now I'm getting $2000 back! You will not be disappointed if you hire this company for your project.

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all!
