The issue in this case could be as simple as poor air exchange in the room. A door that has improper provision for return air will cause poor airflow at the register. There are simple things that can be done to properly balance a system. Assuring adequate return air is first and foremost. If you typically keep doors closed in your home, as I do, there should be a minimum of 1/2" space under the door to allow for return air draw. When I built my own home, I installed return air ducts in every bedroom, to insure proper airflow. Also, removing the register and checking for debris in the duct is advisable. That's something that is almost always overlooked at final cleaning.

There are numerous things that can be done to improve the systems performance as well. Taping the joints in all the accessible duct work with foil tape will go a long way to improving efficiency. Insulating exposed trunk lines and duct piping will help as well.

It is possible that the system itself doesn't provide adequate return air. This is sometimes identified by a vacuum sound at the return air grill. If you hear it sucking, chances are the system is starving itself.

You are probably the 1 out of 10 then.

I've done work for many builders over the years and one thing dictates the quality that's built into a home and that is budget.

Almost every budget minded home buyer expects "a good price", which 9 out of 10 will define as a good square foot number. After all, bigger is better, right?

The problem is, if you want a 2,000 square foot house for 200,000 dollars, sacrifices must be made in the quality and the efficiency of the materials and systems. Often leading to complaints by the homeowner that the builder was a hack.

Quality costs money. A 1200 square foot house with the same budget can be built tighter, more efficient and with better quality throughout, but then the builder doesn't get the job because his price was the same for a house that's 800 square feet bigger.

When people lose the "super size me" mindset, you might start seeing higher quality homes built again.

I guess I'm just fortunate to work for the 10% of people that associate quality with value.

Real good post!!!

Educating consumers about the differences in workmanship really needs to be done better and become more mainstream.

I think the housing crisis and malpractice of most builders within the last 10 years has really opened the eyes of a lot of people. Couple that with "green" building techniques and we are starting to step in the right direction........maybe.

Yeah my statement is broad at first glance, but I know what I see and I'm 100% correct and its horrible. Regardless of customers wanting wine on a beer budget contractors need to use subs who know what they are doing. There are minimum guidelines to follow and they aren't being acknowledged on a massive scale. HVAC is the most complicated of the main construction trades and as a result there are more HVAC contractors that don't know their ass from a hole in the ground.

Have him do a "heat loss" on the house to determine if the furnace is properly sized and also assess the duct situation. I'm sure he'll say that the furnace is oversized and the duct is not sized correctly either. If this is the case I would make a big stink and threaten the builder if he doesn't fix it. These damn builders need to get their nose rubbed in their sh!t more often, they hire the cheapest subs and cut corners everywhere to make more $$$ then when you have a problem they tell you to change your filter...
I agree. I work for a general contracting business building new homes. Yesterday i was doing some plumbing when to my suprise, some mexicans came to do the hvac. Im not racist, but the mexicans were clearly unskilled with the installation. I wouldnt doubt they messed up the sizing. I sized the ducts for that housr based on the unit they installed, and furnace is oversized and ducting is crap

Stupid losers. This is the norm and home buyers have no idea. Mexican workers usually steer clear of HVAC because there is so much to it, I suppose its only a matter of time till contractors figure out that they will work for much less and they can still collect payment even though the system is in shambles.
