I am a new member of the forum. I unsuccessfully tried posting the following question:
"I have an Ultra Aire whole house system installed in my current 3600 sq ft home and it has worked well for 4 years.
I will be moving this summer and I could use some advice in modifying the HVAC system in our new (15 year old) home.
The home is single story, 4600 sq ft home on slab in southwest Florida. It has three a/c units, two of which are 10-15 year old, 2.5 ton units and one is a new 3.5 ton unit. I plan to replace at least one of the older units with higher efficiency unit and I am considering the XT 150H as a part of the new system. I should also note that we do not occupy the home in the summer months.
Can a system be configured using just one XT150H unit? and
Does including the XT150H in the system permit me to economize in any way on the cost of the new A/C components that I will be purchasing?"
I received the following message:
The board administrator has requested that you must provide some message content within your post. You cannot post only HTML, Images, EmotIcons or IFCode.
Perhaps you could post this and let me know why I could not post it.
Thanks, Ross Connecting the return of the dehumidifier to the return of one a/cs and discharging the dry air supply into the supplies of the other two a/cs should work well. Use a tee with balancing dampers to divide the dry air appropriately between the two a/cs. Doing an independent return from the open part of the house and supplying the dry air to the three a/cs supplies also works well. When the home is not occupied during the summer, all the interior doors should be left open, including closets. Also allow the dehumidifier fan to operate continuously to circulate the air throughout the home. I would suggest a/c set as high as possible with the fan in "auto". All of us would appreciate hearing of about your experience with UA in your present home. Thank you for continuing using Ultra-Aire in your next home. The UA XT150H is an excellent choice and should handle the new home. Ken
