I just bought a two story, 1700 sq ft home approx 22 y/o house. I have total of 19 vents/ducts in the house. But I have a problem with the two of them. One vent/duct on the second floor is not blowing any air al all. And the other vent/duct same on the second floor, blows cold air first in about couple minutes then it'll start blowing hot air. For me, it is not normal even though it is still blowing air. What could be the problem? How much will it cost for these 2 ducts to be fix? And I also would like to mention that all the vents/ducts on the first floor are not blowing enough air. Will it help to have a professional to clean the air ducts? Will it improve the air flow?Thanks experts.

Most of them are located on the ceiling except for one that is located in one of the closet. I am pretty sure that it is not for the aire return.

Well - there is more dormant air in vents going to the second floor. The air in them, when the furnace starts blowing, is cold. That has to be blown through before you feel the warm air.
Cleaning the ducts will help with particulates in the air - but probably not affect the force of the flow. You might have the furnace serviced - could be the blower isn't up to snuff..
Also - as for the duct that does not blow at all - all the ducts coming from the furnace have shut-off levers on them. Go down to where the furnace is to see them. It will be a little lever. If the lever is pointing in the same direction as the duct - it's "open". If the lever is turned so it's across the duct, it's closed. Turn it to open the baffle inside the duct, and you should have air flow again.

It is possible that one or two duct lines have come loose or broken, and that you are blowing warm air into the attic. You need to crawl into the attic through the opening in your ceiling and examine the ducts. It might help if the heater was running while you are up there, as you might feel where the leak is. Be very careful where you step, as the drywall ceiling will not carry your weight. Step only on the ceiling joists.
If there is a leak, hopefully you can make the repair using tape. Although many people use duct tape, it is better to use the aluminum tape with adhesive that you'll find in the heating section of Home Depot or Lowe's.
You should also change your air filter periodically. A clogged air filter could be restricting your air flow. Unless you have allergies or asthma, cleaning the air ducts would be of little help. In fact, that might be how your two air ducts were damaged.

its pretty normal for a vent off in the middle of nowhere to be a little cool at first.
the vent that isn't blowing at all may be a crushed/unhooked piece of flex. no big deal. there might even be a shut off damper on that branch line.
don't waste your money on duct cleaning. most of those guys are rip off artists.
you need to have the furnace inspected.any furnace 22 years old will be on its last leg, so be prepared for bad news . if you have an air conditioner that is original to the house, the "A" coil is likely plugged with debris. this will slow air flow. if your furnace and a/c is 22 years old, it would be wise to replace them with modern high efficiency units....the energy savings over 5 years will pay for the new units.

CAT gave you some good answers. In addition I would contact 2-3 HVAC companies and have them inspect the system and do a HEAT/COOLING ANALYSIS to determine the proper size furnace for your residence. If the house is 22 years and the furnace is the same, it might be time for a new one.
It is basically impossible to give you any costs on repairs and or replacements. It varies by company, the area you live in, the furnace efficiency.
Insist on a heat/cooling analysis. Many contractors will only use square footage as a guide and that is wrong. If the HVAC company will not do the analysis, find another one.

As far as the duct that does not blow anything it is most likely located on or by an inside wall. This is a cold air return and it will not blow out any air it pulls air in.
The other that takes a little bit to blow hot air that is normal as well.

Call a heating and cooling specialist. Your heating unit may need to be replaced.
