Southern Room too hot
 
1 Attachment(s)
Hey guys! It's me again. This thread is a little different from last time. I had a "specialist" come in an install a duct fan. The friggin' thing is so loud though!

Now, the air comes out of the vent full blast (almost) but the air isn't that cold at all compared to the northern rooms.

I don't know what else to do. He even recommended growing a tree in front of the house or getting one of those shade things. HUH? Come on! I know there's someone out there who has the same problem but has a fix? What about the people in 113 degree climates, like Arizona?

I thought about a window unit.... but due to theft and security issues.... I rather not. People are getting too bold these days.

I have attached a picture of my house. The room with a window is the problem room. As you probably notice, it's the only room that sort of "sticks out" from the rest of the house. Many of the neighbors' homes are built the same way and as a result, they don't even use their rooms.

How does the duct work run? Does it run through a crawlspace or basement, or a attic? If it is in the attic, I would be checking the insulation around the duct work, to make sure that it is secured, and not allowing warm attic air to bet through.

It runs through a basement with an open ceiling.

Sounds like your duct isn't sized correctly and will need to be remade for the system to work right. Here's a random link to a manual J (calculating heat gain/loss) and a manual D (duct design) if you want to DIY

2 things to try...1st. Providing your filters and fan blades are clean, try running your furnace fan on constantly for about a day..if temperature is satisfactory..have a relay/electronic control board installed to run the fan on constant low speed and switch to high speed when thermostat calls for cooling.when in cooling mode. This circulates the cool air throughout the house providing even temperatures throughout. Most furnaces are equipped with multi speed fans these days..2nd..suspect you may need roof vent for attic above that portion of roof. Hot air will get trapped making the room too hot...I'm betting on the constant fan making a huge improvement...also make sure there is a return duct in the room or leave the door open or install grille in door to promote best circulation possible

Agree about the duct sizing. Booster fans are nothing more than bandaids on a poorly designed duct system. Assuming the system is large enough for the house, then you should be able to adequately cool the whole house if you can get enough air into the room (that's where Manual D comes into play).

That said, duct replacement can be expensive, and other suggestions (like running the fan continuously) might help the situation.

How much does anyone want to guess, that there is not enough return air on the system.

I would go with a seperate unit such as a Mitsibusi split unit. Bonus rooms are always problems to heat and cool.

Problem is, that does not appear to be a bonus room, but a part of the orig. build.

Kinda like the garage was put before the room.

LOL. I've been busy contacting multiple sources regarding this problem. I apologize guys. I've been taking all of this in consideration and I'm not rich. Personally, the only reason why I think he installed the booster fan was to make a quick buck.

All in all, it looks like I'll have to settle for a portable air conditioning unit. I'd like to go window, but times are hard and people are crazy nowadays.

The only thing is, emptying the accumulated water, even in a condensation recycling unit, must be emptied from time to time.

Also, the humidity in the room is not extreme, but I rather have cool air at all times :\

Did you try running the furnace/AC Unit fan continuously to see if the room temperature improved. Usually works.:thumbsup:

I actually have some nice UV curtains in. The room is completely dark 24/7. I would have thought that might make a difference... but no lol :huh:

I will forward this information to the HVAC guy. He mentioned something about finding out if the fan speed can be increased. He also said that increasing the speed might not be a possibility because it could actually decrease the dehumidifying affect.

I will mention that to him though. Also, wouldn't running the fan 24/7 significantly lessen the life of the fan? :(
